Perhaps one day in the future, the endless streets will be driven by self-driving and zero-emission vehicles. These vehicles not only communicate with each other, but their appearance also makes the city's traffic environment more green and efficient.
The car will search for the parking location on its own and then automatically charge it. In addition, they will be equipped with a wealth of in-vehicle communication and entertainment options. Passengers no longer need to “own†a car, and they can easily meet their travel needs by renting or booking on a smartphone.
These future visions are currently in their infancy, and the key to realizing this vision is time issues and the need for support from the public.
According to market research firm IHS AutomoTIve, by 2025, sales of electric vehicles (EVs) and hybrid vehicles (HEVs) will account for a quarter of global car sales.
As transportation continues to change, Texas Instruments (TI) is committed to driving cars toward greener, safer and more reliable. TI's technology can help HEVs reduce greenhouse gas emissions, while zero-emission pure electric vehicles also incubate new automated business models.
Today's full-hybrid cars can reduce fuel consumption by half, while plug-in hybrids can reduce fuel consumption by 80%.
At present, the new factory car contains more than 6,000 semiconductors, and this data will continue to grow substantially as cars are becoming more intelligent, such as battery management, traction inverters, car chargers and More and more automotive components, such as DC/DC converters, are gradually becoming electronic.
TI's engineers have been behind the scenes to help develop this trend, from automotive infotainment systems and power management systems to connectivity and advanced driver assistance systems (ADAS), where new semiconductor components are being developed.
In fact, some automakers already have a large number of their own car sharing models, and all major OEMs such as Google, Lyft, Tesla and Uber are developing driverless vehicles. Driverless trucks have also been tested on the road in the US, Europe and Australia.
back to the FutureSo far, HEV has been more popular with consumers than EV. This may be because although EV is more environmentally friendly, the cost is relatively higher, and the full performance of the gasoline internal combustion engine cannot be exerted. However, at the recent Paris Motor Show, almost all car manufacturers have introduced new electric or hybrid models.
The large-scale promotion of pure electric vehicles will take time. It is for this reason that TI has focused on the HEV innovation in the transition phase and the full electronicization of automotive power systems.
HEV brings fuel efficiency and automation, but the batteries used today are limited by the number of recharges and cruising range. In terms of HEV, TI is developing high-voltage technology, including battery management, sensors and advanced monitoring, as well as 12V dual power rails and an additional 48V rail for high-power applications for better fuel, battery and cost efficiency.
The popularity of consumer EVs outside urban areas has been limited due to lower range of cruising range and longer charging times. One solution is to increase the battery voltage to 800V, which will reduce the charging time to 20 minutes (up to 80%) and the range of 300 miles.
AutopilotBy monitoring road conditions, switching signals, and communication between vehicles, integrated circuits can make cars more autonomous. TI's sensors have been used in driver assistance and autonomous parking systems, with the ultimate goal of creating a fully automated vehicle.
Compared to most drivers, autonomous vehicles can achieve higher fuel efficiency, especially in urban environments where constant speed is required. At the recent Paris Motor Show, industry experts also announced that autonomous vehicles are safer and can significantly reduce the number of traffic accidents and reduce casualties.
By 2020, most automakers will introduce EVs that fully or partially autopilot.
According to IHS Automotive's forecast, with the increasing popularity of driverless cars, by 2035, the number of vehicles with a certain degree of autopilot will increase to about 21 million, of which about 4.5 million in the United States.
Looking to the futureSeveral factors are driving the growth of electric vehicles, including legislation specifically designed to reduce emissions, technologies that are integrated into consumer products to improve driving safety, and the transition from car ownership to mobile services.
