Safety first, Wei brand executives call on consumers not to trust assisted driving too much



IT House reported on August 18 that Wei Brand CMO Qiao Xinyu discussed the issue of autonomous driving technology on Weibo.

He said, “The industry says that 2022 is the first year of LiDAR, but I don’t see it. At present, many intelligent assisted driving does not cooperate with LiDAR, so I would like to share a few tips with you:

1. Assisted driving is not driverless, especially for vehicles without lidar, we cannot challenge fancy marketing at the cost of our lives;

2. In critical situations, active braking only applies limited braking to the vehicle in order to reduce the speed of the vehicle in the event of a possible collision.

In addition, for the “first year of lidar on the bus”, he said:

It is really not to install lidar, or to actually get on the car, but to really realize “urban assisted driving”. Some models of friends and merchants are also equipped with lidar, but only in high-speed conditions. For assisted driving, urban assisted driving is facing the application of urban road conditions with more complex road conditions, which is the “university” level.

Wei brand new models have realized intelligent navigation in cities such as intelligent following navigation path, intelligent traffic fork, intelligent identification of traffic lights, intelligent avoidance of obstacles, intelligent lane change, etc., which meet the intelligent assisted driving of high-speed and urban scenes.

I dare to say that this is the first high-end new energy source in China that realizes mass production of perception-oriented urban assisted driving.

As we all know, autonomous driving is currently divided into six levels from L0 to L5 in the industry, which is also the global industry reference standard for commonly used automated/autonomous vehicles. The six-speed standard is listed separately from no automation to assisted driving, partial automation, conditional automatic driving, highly automatic driving, and fully automatic driving. At present, most of the industry is in the L0 to L2 level, and the mass-produced L3 seems to be only the Honda Legend.

IT Home understands that the six levels can be briefly summarized as follows:

  • L0: The driver is fully driven

  • L1: The driving system can sometimes assist the driver to complete certain driving tasks;

  • L2: The system can complete some driving tasks, but the driver needs to monitor the driving environment, complete the remaining part, and at the same time ensure that there is a problem and take over at any time. The wrong perception and judgment of the automatic system can be corrected by the driver at any time. L2 can be divided into different usage scenarios based on speed and environment, such as low-speed traffic jams on loops, fast driving on highways, and automatic parking by drivers in the car;

  • Level 3: Some driving tasks can be accomplished and the driving environment can be monitored in some situations, but the driver must be prepared to regain driving control (when requested by an automated system). So at this level, the driver is still unable to sleep or take a deep rest. Due to the particularity of L3, the most meaningful deployment is to upgrade on high-speed L2;

  • L4: In certain environments and specific conditions, it can complete driving tasks and monitor the driving environment; L4 deployments are currently mostly based on urban use, which can be fully automatic valet parking, or directly combined with taxi-hailing service to do it. At this stage, within the scope of automatic driving, all tasks related to driving have nothing to do with the driver and passengers, and the responsibility for perceiving the outside world lies in the automatic driving system;

  • L5: All driving tasks that the automated driving system can perform under all conditions.

Also published“Automotive Driving Automation Classification” refers to L1-L2 as assisted driving, and L3-L5 as automatic drivingthe intuitive and detailed definition can more accurately convey the automation level of the vehicle and enhance the public’s awareness of the automation level.
