The safety of automobiles has always been considered the most important feature of automobiles and is a key driver of automotive technology development. In the new energy vehicle industry, there has recently been a big discussion about AEB. In addition to watching this discussion, the author was attracted by a third-party evaluation of BYD's AEB** on the Internet, so to speak, with this paragraph**, the author believes that BYD's intelligence level is much higher than the general stereotype, even in the first echelon of the intelligent driving level.
For driving, we generally know that a skilled driver with excellent driving skills must be a driver who can see far and can brake the car at a suitable distance before the risk occurs. And BYD's **, that is, in a high-speed environment, with 130km h for the stationary front car, 110km h for the front car that suddenly disappeared, and 110km h for the stationary front car at night, can effectively identify and automatically brake, then at least BYD's AEB level is quite high.
To put it simply, if you want to achieve automatic braking at 130km h, then the detection distance of the vehicle must be very, very far, and secondly, the obstacle must be accurately judged, if the obstacle is stationary, the vehicle will hit it before it has time to react, and if the car in front has been driving and the vehicle has automatically braked, then it is not only an overreaction, but also the risk of rear-end collision after the car, so this test** Under these three conditions, it is a great challenge for the detection and judgment ability of the vehicle, and behind these two capabilities is the system computing power of the entire AEB system.
As we all know, AEB (Autonomous Emergency Braking), that is, "Automatic Emergency Braking System", is an active safety assistance function, which is mainly composed of a distance measurement module, a control module (ECU) and a braking module. For the first time, BYD proposed the concept of a vehicle fusion perception platform, which integrates sensor data such as cameras and radars with real-time data of the vehicle, and indirectly sensing the physical sensing of the vehicle + indirect sensing by software algorithms, giving the vehicle a strong perception ability. The intelligent module on the vehicle is controlled and adjusted according to its own characteristics, and the control platform carries out scientific distribution algorithms, selects and makes decisions to accurately control various components of the vehicle, and realizes the efficient implementation of millisecond-level control response of the steering, driving and braking systems, and identifies early, corrects and accurately controls the danger before it occurs. In July this year, BYD released a high-end intelligent driving assistance system called "Eye of the Gods", and in the recent winter test, BYD's various models have successfully cleared customs, which fully proves that BYD's intelligent driving level is far underestimated.
At a speed of 130km h, BYD can achieve automatic braking, in fact, in China's current road regulations environment, it can already achieve absolute safety in all scenes. Of course, this is just a test**, AEB is the last line of defense to avoid driving risks, in short, no matter what, there are thousands of roads, safety first, everyone should be more careful when driving, and can not be taken lightly because of the advanced AEB system.
