As we all know, BYD's new energy technology is now recognized as the first echelon, whether it is DMI or E platform 30, any technology can be used to feed a car company. The chassis shortcomings that have been criticized before are also being made up at a rapid pace, with upper wishbone + five-link suspension, Yunyuan, and ITAC intelligent torque control technology making BYD's new energy vehicles have a comprehensive improvement in handling and comfort. The recent controversy between Wenjie and Xiaopeng about AEB has made everyone focus on the direction of intelligent driving, and many people have said that BYD's intelligent driving has dragged its feet.
Is that really the case?Let's take a look at the recent third-party review of the U8 AEB before making a conclusion.
AEB stands for Automatic Emergency Braking System, which is an active safety assistance technology that includes two functions: collision warning and automatic emergency braking. To put it simply, AEB uses radar and cameras to detect pedestrians, vehicles and other obstacles in front of it, measure the distance to the vehicle or obstacle in front, and then compare the measured distance with the alarm distance and safety distance, and when it is less than the alarm distance, it will trigger a collision warning, and when it is less than the safety distance, even if the driver does not have time to press the brake pedal, the AEB system will activate emergency braking, so as to avoid or mitigate the collision.
It can be seen that the AEB system is a very important active safe driving technology, and the detection distance and accuracy of the system, the speed of system response and the stability of system operation are very high. Let's take a look at the AEB system test released by Sina Technology for the Yangwang U8.
This test was mainly tested for U8 in three scenarios:1The speed of 130km h during the day, the front car is stationary, and the main test is the detection distance and accuracy of the system2.The speed of the vehicle is 110 km h during the day, and the vehicle in front suddenly leaves the lane and merges, mainly to investigate the response speed of the system3.At a speed of 110 km h at night, the vehicle in front is stationary, and the stability of the system is mainly investigated in low light. In all three tests, the U8 can do a good job of recognition and braking.
Many people may think that this is not the normal level of car companies, but it is not. At present, most models can only achieve car-to-car braking in the 60km h speed range, when the obstacles in front are replaced by pedestrians, two-wheeled vehicles and other small targets, the success rate will also decline to a certain extent, and some models that are good at intelligent driving can achieve 80-100km h braking, looking up to U8, the 130km h speed to achieve automatic emergency braking has absolutely refreshed the industry's cognition.
From this evaluation, it can be seen that BYD's so-called intelligent driving is not good but it is conservative in terms of active driving strategy, and in terms of active safety technology, BYD's technology feels that it is first-class, but there is usually less publicity, and many consumers don't know it. The low-key BYD pretended to be forced again this time.
