At the “Autonomous Driving Sub-Forum” of the 2020 China Electric Vehicles Forum held recently, Jiang Jingfang, Senior Vice President of Bosch Chassis Control System China, said that autonomous driving is the development trend of future cars, and it will also show a prairie prairie trend in China.
According to reports, Bosch is divided into three areas for commercial development in autonomous driving assistance. Up to now, in the field of automatic driving assistance, Bosch has helped more than 30 L2-level models in China to have single-lane automatic driving assistance functions. Higher-level research and development work continues in the two areas of parking.
Jiang Jingfang said that at this stage, L2 autonomous driving has been implemented, L2+ or L2.5 is just around the corner, L3 and above autonomous driving is still under discussion, and L4 and L5 autonomous driving needs more cooperation, including ICV, intelligent network connection, etc.
2018 is the first year of L2, and more and more models are equipped with this function to realize automatic following in the lane. In the past two years, Bosch has reached cooperation with Geely, Great Wall, Changan, SAIC and other OEMs, and the L2 has achieved mass production on more than 30 models. In addition, Jiang Jingfang said that the OEMs equipped with Bosch’s systems have already achieved mass production, and more models will be mass-produced in the future. At the same time, many OEMs have begun to go abroad.
In terms of parking assistance systems, Bosch and Daimler have cooperated in the development of automatic valet parking technology as early as 2015. Up to now, Bosch has more than 20 models on the market. The automatic parking assist can effectively search for a parking space, and the system can automatically steer, shift, and brake automatically to achieve fully automatic parking. Jiang Jingfang said that fully automatic parking assistance can bring users a good parking experience, so it has gradually become the mainstream of the market.
Jiang Jingfang revealed that this year, Bosch will mass-produce a remote-controlled parking assist car that relies on the fusion of ultrasonic radar and surround-view camera, and controls the car through a smart key or mobile phone.
In contrast, L3-level autonomous driving still faces many challenges. Jiang Jingfang said that L3 faces many bottlenecks, the number of sensors needs to be multiplied, the system cost is extremely high, and the security challenges are also very large. At present, the world is delaying the mass production of autonomous driving, and the development route of Bosch L3 autonomous driving in China is also being explored.
For L4 and L5 autonomous driving, it is also difficult to achieve. Jiang Jingfang believes that the industry needs more cooperation. In December 2019, the autonomous taxi jointly built by Bosch and Daimler was launched in San Jose, California, USA. For the past two or three years, the two parties have been working together to build autonomous driving systems and vehicle management software for Level 4 and above.
At the end of his speech, Jiang Jingfang emphasized that Bosch has been committed to building local technical capabilities in China, especially in the field of artificial intelligence and high-precision maps, and more partners need to be joined; all Bosch development projects take into account the driving environment and road conditions in China, At the same time, it also actively cooperates with industry law-making departments and industry leaders to jointly establish and improve autonomous driving regulations.
