    Tampa's connected vehicle project aims to make driving safer

    There’s no doubt that connected vehicles are the way of the future, as any number of initiatives from all corners of the tech spectrum illustrate. The 5G Automotive Association (5GAA) for example, is a collaboration of vehicle manufacturers, tech companies and the telecoms industry that wants to come up with a more universal solution for our future mobility and transportation needs. Being connected is central to that. Complex problem However, this is a complicated and not easily solved issue. Standardising how vehicles, and indeed everything else from your household’s white goods to pets, prams and coffee percolators connect, is still far from clear. Whatever connectivity method is used, joining up the dots between vehicles, devices and people is certainly the way forward, particularly in urban areas where city populations are on the increase. One example in the USA aims to tackle the urban issue head-on. The Tampa Hillsborough Expressway Authority (THEA) connected vehicle pilot is a great new initiative designed with making streets in the Florida city safer and much more efficient. To do this, the city has been working with Siemens to develop a network of wireless boxes or Vehicle to Everything (V2X) roadside units (RSUs) that effectively join up those dots between vehicles. Connected tech This network of 46 roadside boxes is so far linked to around 1,000 car-owning volunteers along with 10 buses and ight streetcars. It’s just one of a handful of pioneering projects in the US, including one in Wyoming and another in New York City, aimed at streamlining traffic flow and cutting down on accidents. To do this THEA is utilising vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication technology to make it all work. The local authority signed an agreement with the US Department of Transport (USDOT) back in 2015 and the Tampa/Hillsborough Regional Expressway Authority (THEA) has been working alongside the Hillsborough Regional Transit Authority to implement the concept. They already had a solid foundation, after realising the benefits of all-electric tolling systems. The Connected Vehicle or CV project seemed like an obvious extension of that. Dynamic warnings For the Tampa project, CVs communicate using a two-way short-to-medium-range wireless tech called DSRC or Dedicated Short Range Communications, which is a bit like Wi-Fi. This doesn’t mean the car, bus or whatever it might be is automated or autonomous as the driver has full control at all times. However, it does mean the driver can receive a series of dynamic warnings on the go, including audio and visual indications for end of ramp deceleration and forward collision alerts, amongst others. We recently got to see the pilot in action and it boasts a number of potential solutions, all of which are tied into the connected vehicle concept. City officials even closed off a portion of the Lee Roy Selmon Expressway for us in order to illustrate the various facets of the project. Ther...

  • Israeli startup uses auto technology to fight COVID-19

    Israeli startup uses auto technology to fight COVID-19

    Standing in a lengthy line at a grocery store or sitting in a crowd at a sporting event once seemed like the most ordinary of activities. Amid the coronavirus outbreak, they’re unfathomable. For the world to reopen, governments and businesses must find ways to ensure gatherings of people don’t threaten the health of workers or consumers. Adasky, an Israeli auto-tech startup, thinks it has found a way to accelerate a return to something resembling a normal way of life. In regular times, Adasky develops thermal-imaging camera technology for use in driver-assist systems and autonomous vehicles. But two weeks ago, company leaders and software engineers met for a brainstorming session on how they could help thwart COVID-19. Within a matter of days, they cobbled together prototypes that relied on their camera technology’s ability to measure heat. Instead of detecting objects on a road, that capability can now be used to measure the precise body temperature of prospective buyers at a car dealership, sports fans — anyone in public places. “After what we are witnessing now, the world after is going to look different in many ways,” Adasky CEO Yakov Shaharabani told Automotive News. “Technology will overcome the need for us to do what we’re doing, which is isolating ourselves. Technology will, step by step, help us get back to the world we knew a few weeks ago.” This week, the company will deploy cameras for temperature-taking applications in multiple Israeli hospitals. Those field tests will serve as an important validation tool, though internal testing has revealed accuracy down to a hundredth of a degree. Of course, the cameras cannot discern whether a person has the coronavirus. They merely serve to spot elevated body temperatures, a telltale symptom. That alone might be an important tool for maintaining vigilance and reassuring workers and consumers alike that best public-health practices are being followed. “I can definitely see a situation not far from today when these thermal cameras will be in all public areas, kind of like fire extinguishers,” Shaharabani said. He said Adasky has already had conversations with potential users who see benefits in ensuring high-profile CEOs and senior government officials are not in proximity to anyone who has a fever. The camera is the same used for automotive purposes. What’s changed is the software. Normally, it detects heat at ranges needed for automotive applications, but the camera was tweaked to work at short ranges and focus on taking temperatures from a specific body part, typically the head. The cameras can work passively from afar — they don’t need to be held — and they can gather temperature information simultaneously on anyone in their field of view, avoiding the need for queues of people waiting to be scanned. At mass scale, Shaharabani says it’s possible the cameras would cost less than $100 each. Only a month ago, he would never have envisioned such a new line of prospective business. On March 23, Ad...
  • AR HUD Design Solutions

    AR HUD Design Solutions

    There are different kinds of optical applications for HUD product, such as TFT (Thin Film Transistor), DLP (Digital Light Processing), and LBS (Laser Beam Scanning). The features of these techniques are as follows: •  TFT: Brightness 800~12000nits, projection becomes blurry when zooming in. Low light utilization, inefficient energy management that requires space and design for heat dissipation. •  DLP: Brightness 150lm @12W, 200lm @16W, with large projection size. Low light utilization, inefficient energy management that requires space and additional design for heat dissipation. •  LBS: Laser Bean Scanner, Brightness 25~50lm @3.7~6W, with large projection size. Easier heat dissipation. These optical projection techniques have been applied into automotive HUD products, like current HUD, WHUD and future AR HUD, in the market. HUD Display (2013~2018) uses TFT- LED panel, translating image that is projected information onto the vehicle windshield. It displays as 2D flat visual image, small virtual image with car speed, time, incoming calls and navigation, but its lack of distance perception and icons will block the front view upon driving. The WHUD Display (2017~2019) uses TFT-LED panel or DLP projection technique, projected the image directly to the windshield. However, poor brightness and contract might let the images being blurred and it doesn’t integrate to the front view, lacking of AR visuals with the driving environment. FIC LASER AR HUD (2019~Now) uses LBS projection, its high brightness makes it readable under the natural sunlight and provides distant perception (VID 2~20M). It is being able to see through the virtual images without blocking the front view. The HUD is relied on a projection device, optical technique and the light source in order to project the clear and correct information onto the car windshield. For this, FIC LASER AR HUD is using Laser as its light source and combing with optical glass design to create rich virtual images. An optical imaging element determines the shape, distance and size of the AR HUD images. The image appears to float freely over the road, the windshield acts as a deflecting subject. The AR HUD display composed by the following components: cover glass, curved mirrors, plane mirrors, diffusers (projection display), LBS, optical correction software, PCB/PCB assembly, SW flow chart, and housing/box-build. FIC designs AR HUD through design development, verification and analysis process, and cooperates with car manufacturer, windshield glass supplier and optical system supplier together, as working with car manufacturers to define imaging position, size and information, system integration, and final detection system and software testing in order to supply the best experience effect of the product. About FIC AR HUD image blending portions, the size of IP structure design & projection angle will affect the display image size and distance differently. The projection angle is from 5°, 10° to 2...

    Samsung announced that it will launch 600 million pixel image sensing: breaking the limit of human eyes

    With Samsung's ISOCELL HM1/HMX sensor, some mobile phones have taken the lead in carrying a 180 million pixel camera, bringing new possibilities for photographing. It was reported that Samsung is developing a 150 million pixel Nonacell image sensor. However, Yongin Park, executive vice president of Samsung LSI, said in the latest article published on the official website that they are preparing to develop a 600 million pixel (600 MP) sensor product, directly breaking through the human eye limit (about 500 million pixels). Similar to the current 108MP sensor's nine in one technology, at the scale of 600MP, Samsung is bound to use multi-pixel synthesis technology to simulate the background and improve the quality of the chip, which may require the introduction of new materials and other technologies. In addition, Yongin Park also mentioned that the Samsung LSI sensor can capture light waves beyond the human eye (450nm to 750nm away), such as ultraviolet sensor can be used to detect skin cancer, infrared sensor can be used for industrial quality control, etc. It is reported that Samsung's 600 million pixel CMOS size will be relatively large, which may not be for smart phone development, but for Autonomous driving, Internet of Things and other fields. ──Source: Mydrivers
  • Extending subsidies may not reverse EV decline

    Extending subsidies may not reverse EV decline

    SHANGHAI -- Beijing, aiming to help the electrified-vehicle sector pull through the coronavirus outbreak, last month extended subsidies for full-electric vehicles and plug-in hybrids for two more years. Despite the extra support, electrified-vehicle sales likely will shrink more severely than the broader new-vehicle market in the near future. It’s already happening. Equally impacted by the viral outbreak, demand for electrified vehicles fell much more than overall new-car and light-trucks sales in March, as well as in the first quarter. In March, while China’s overall new-vehicle sales slipped 43 percent to 1.43 million, combined deliveries of new EVs and plug-in hybrids dropped 53 percent to about 53,000. In the first quarter, total new-vehicle sales dropped 42 percent to 3.67 million. Demand for new EVs and plug-in hybrids slumped 56 percent to 114,000. In addition to the pandemic, China’s electrified-vehicle market hasn’t fully recovered from the blow when subsidies were drastically cut by Beijing in June 2019. Back then, when it intended to phase out the incentive program by the end of 2020, the government scaled back subsidies for EVs by 60 percent and halved the amount for plug-in hybrids. With the new cuts, full-electric passenger vehicles qualify for subsidies of up to 25,000 yuan ($3,531) and plug-in hybrid cars are granted a flat 10,000 yuan break. Even with the latest extension, it’s hard to predict how soon China’s electrified-vehicle market will shrug off the dampening effect of the subsidy cuts. With the global economy sliding into a recession, oil prices have tumbled. Prices of gasoline and diesel in China have dropped 27 percent and 30 percent, respectively, in the first three months. For car shoppers, the sharp decline in fuel prices has undermined the appeal of subsidies on electrified vehicles. It also remains to be seen to what extent the carbon credit program Beijing implemented last year can push automakers to expand electrified-vehicle output. The program requires passenger-vehicle makers to earn one carbon credit for every 100 vehicles they produce. It allots a fixed two credits for a plug-in hybrid and two to five credits to an EV depending on its range -- the longer the range, the higher the credits. Under the program, carmakers must earn an amount of credits equivalent to 10 percent of their annual output in 2019. The rate will rise to 12 percent next year. Reflecting the large number of electric cars churned out by Chinese carmakers such as BYD and BAIC Motor Co., China’s passenger-vehicle industry ended 2019 with a surplus of more than 3 million carbon credits, according to a tally the Ministry of Industry and Information Technology released last week. The huge surplus allows foreign automakers, most of which are short of carbon credits because of limited electrified-vehicle output, to purchase credits from domestic automakers at relatively low prices. And it explains why most international carmakers are sticking to t...
  • Accelerating battery charging speed, Stanford research uses AI as magic key.

    Accelerating battery charging speed, Stanford research uses AI as magic key.

    The key to the popularity of electric vehicles lies in whether the charging speed of batteries can be improved, which can gradually make charging as convenient as fuel charging. Both battery and electric vehicle manufacturers are committed to the research and development of fast-charging technology. A team from Stanford University, Massachusetts Institute of Technology and Toyota Research Institute published a new study in Nature, revealed how artificial intelligence could speed up the testing process required for novel charging techniques. The problem of battery fast charging is that under the condition of fast charging, the degradation rate of battery will be accelerated, and even the risk of overheating and fire. However, to evaluate the impact of different charging methods on the battery, hundreds of charging and discharging cycles must be carried out until the battery fails to test the battery life. Every new battery composition or every new charging method can only make out the results after such a long charge discharge cycle, and then it can be improved by waiting for hundreds of charging and discharging cycles to see how the new results are. It is conceivable that the speed of R & D is bound to be greatly encumberd. The research team applied artificial intelligence to solve the problem of time-consuming experiment. The research started in 2017 when Toyota Research Institute invested 35 million US dollars for research on artificial intelligence auxiliary battery, the original goal is to develop new battery materials. In 2019, the research team changed to use artificial intelligence to assist the computer to simulate the battery charging and discharging cycles. It only needs 9% of the actual charging and discharging test time, so it can evaluate 224 possible high-cycle-life charging processes in just over two weeks. Undoubtedly, this will greatly increase the research and development speed of fast charging. With the development of battery technology and charging technology, the service life is getting longer and longer. The time from charging and discharging cycle to the end of service life will be longer and longer. Computer simulation will be a compromise solution. First, find out the best possible technology through computer simulation, and then conduct field test, which can greatly reduce the time of trial error. Artificial intelligence is not only applied in the research stage, but also in the Canadian new business, GBatteries, uses artificial intelligence directly to accelerate the charging speed. When fast-charging, artificial intelligence can evaluate the battery condition at any time. Once it may cause battery damage, suspend charging to avoid irreversible damage to the battery. It can avoid damaging the battery and charge at the fastest possible speed. GBatteries technology is currently only applied to small batteries. When it is used in electric tools, the charging time can be reduced from 30-60 minutes to 11 minutes. However...
  • Digital Instrument Cluster Design Solution

    Digital Instrument Cluster Design Solution

    The virtual automobile cluster replaces the most representative parts of the existing cluster such as indicators and digits with a screen. Its advantage is that users can define their own instrument system to meet different requirements, which is more powerful, flexible and easier to connect with the network, peripherals and other applications. Virtual automobile instrument cluster benefits from more powerful graphics processing and display effect, more indicators are designed by quasi-physical method, which can effectively shorten the user's acceptance process. Multimedia entertainment information and basic vehicle information can also be displayed more logically, centralized display helps to improve driving safety, and driving sight does not need to switch frequently in multiple locations; in addition, simplicity The design can also leave more space for the ride area or storage. Although LCD technology is mature now, it is not only simple to install a LCD cluster on a car with a display screen. In fact, this is rather complex system engineering. After changing to LCD screen, first of all, the vehicle information presented to drivers is much richer than the traditional instrument cluster. The collection of information, the cooperation of LCD cluster and sensor, the precision adjustment of display instrument and so on, all need to be overcome one by one by the car manufacturers. And each vehicle must undergo strict high and low temperature test before mass production; as part of the whole vehicle, the instrument panel module should also meet the same high and low temperature test standards. But because the space in the dashboard bin is relatively small, and the GPU of the LCD module, the display screen and so on will heat up in the use process. The higher resolution of LCD screen, the higher the calorific value. Therefore, finding or developing a suitable hardware product for vehicle interior environment and matching a set of hardware environment to meet the requirements of vehicle use are also technical difficulty that the R&D team has to overcome. With 40 years of design experiences by implementing NXP solutions, FIC products coupled with rising digitization that leads to everything seamless connected. We offer wide range of edge computing cuts across the IoT, from S.M.B, building automation and to the most complex vehicle with variety of NXP solutions in order to design and produce automotive digital cluster for your special needs.
  • BYD's new blade battery set to redefine EV safety standards

    BYD's new blade battery set to redefine EV safety standards

    BYD has officially announced the launch of the Blade Battery, a development set to mitigate concerns about battery safety in  electric (EV). At an online launch event themed “The Blade Battery – Unsheathed to Safeguard the World”, Wang Chuanfu,  BYD Chairman and President, said that the Blade Battery reflects BYD’s determination to resolve issues in battery safety while  also redefining safety standards for the entire industry.  The Blade Battery has been developed by BYD over the past several years. The singular cells are arranged together in an array  and then inserted into a battery pack. Due to its optimized battery pack structure, the space utilization of the battery pack is  increased by over 50% compared to conventional lithium iron phosphate block batteries. While undergoing nail penetration tests, the Blade Battery emitted neither smoke nor fire after being penetrated, and its surface  temperature only reached 30 to 60°C. Under the same conditions, a ternary lithium battery exceeded 500°C and violently burned,  and while a conventional lithium iron phosphate block battery did not openly emit flames or smoke, its surface temperature  reached dangerous temperatures of 200 to 400°C. This implies that EVs equipped with the Blade Battery would be far less  susceptible to catching fire – even when they are severely damaged. The Blade Battery also passed other extreme test conditions, such as being crushed, bent, being heated in a furnace to 300°C  and overcharged by 260%. None of these resulted in a fire or explosion. He Long, Vice President of BYD and Chairman of FinDreams Battery Co., Ltd., covered four distinct advantages of the Blade  Battery including a high starting temperature for exothermic reactions, slow heat release and low heat generation, as well as its  ability to not release oxygen during breakdowns or easily catch fire. In the past few years, many EV manufacturers have fallen into a competition for ever-greater cruising range. When the range  becomes the prime factor to consider, this focus is then transferred to power battery makers, leading to unreasonable pursuits  of “energy density” in the battery industry. It is due to this unpractical focus on “energy density” that safety has been sidelined  from power battery development. BYD’s Blade Battery aims to bring battery safety back to the forefront, a redirection from the  industry’s tenuous focus on this crucial aspect.
