The luck of BYD lies in Wang Chuanfu's determination to maintain independent research from the beginning to the end. If there is no technical reserve of ESP, it is very difficult to develop the technology of ONE-BOX alone. Why do you say that? Because the brake-by-wire is a product integrated on the basis of ESP, and the ONE-BOX technical solution integrates the functions of ESP. In fact, Bosch has long known that BYD has developed a BSC braking system similar to IPB, and knows that BYD has high technical strength to jointly develop IPB. Just like the new anti-skid technology dTCS jointly developed by BYD and Bosch, Bosch is interested in BYD's powerful motor control technology. The reason why Bosch chose to jointly develop with BYD is that BYD has a deep understanding and mastery of the three-electric technology. When the sensor detects that the vacuum level of the vacuum booster is insufficient, the electronic vacuum pump starts to work to maintain the vacuum environment. What should I do? One of the easiest ways is to keep the original vacuum booster of the fuel vehicle, and then connect the other end to the electronic vacuum pump. A pure electric vehicle has no engine, and without an engine, there is no vacuum. In other words, the engine provides auxiliary braking force to your brake pedal.īut here comes the problem. The reason why you can easily step on the brake pedal is mainly because the vacuum booster has sufficient vacuum, and the vacuum is provided by the engine power. If you don't believe it, you can step on the brake pedal a few times after turning off the car. If there is no vacuum booster, the brake foot will feel very hard, and it feels like you can't step on it at all.
In other words, the harder you step on the pedal, the harder the car brakes. This braking system mainly uses a vacuum booster to amplify the strength of your foot on the brake pedal.
