Careful consumers will find that some of the new cars launched this year, such as Palio, Siena, Formerly and other cars, have the English letters of EBD on the braking items, and they are incompatible withABS(Anti-lockBraking System) Are linked together, often written as "ABS+EBD". What is EBD and why should it be linked with ABS?
The English full name of EBD is Electric Brake force Distribution. The Chinese literal translation is electronic brake force distribution. Then, with ABS, what does electronic brake force distribution do and what role does it play?
carBraking should emphasize stability and avoid braking deviation. The key to avoid braking deviation is the rear wheel. When a car is braked at a high speed, the rear wheel side slips (ie, lateral sliding) is the most dangerous situation. It will cause the entire car to undergo uncontrollable slewing motion, which is very prone to collision accidents.
During the braking process of a car, if the wheel is not locked, the wheel itself has the ability to withstand a certain lateral force. The car will not side slip under the action of general lateral interference force, but once the wheel is locked, the wheel will The ability to withstand lateral forces is immediately lost, and the car is prone to sideslip under the action of lateral interference forces.
Ordinary for assemblyBrakeFor most cars, it is inevitable that the wheels are locked and slipped during braking. Theory and practice have proved that on a straight road, if the front wheel locks and slips first during braking, the car can maintain a straight deceleration and stop, and the car is in a stable state. If the rear wheels lock up earlier than the front wheels, even half a second faster, the car will flick or spin under the action of the lateral interference force. The higher the braking speed, the

If the rear wheels lock up earlier than the front wheels, even half a second faster, the car will flick or spin under the action of the lateral interference force. The higher the braking speed, the more serious this phenomenon will be. Therefore, the first locking of the rear wheels is very easy to cause the vehicle to lose the stability of braking.
In order to prevent the rear wheels from braking first when the car is braking, engineers have developed a system that specifically detects the braking conditions of the rear wheels—EBD. EBD can control the braking process according to the weight of the vehicle and road conditions, and automatically compare the rear wheels based on the front wheels.tireIf it is found that there is a difference between the front and rear wheels, and the degree of the difference must be adjusted, it will adjust the automobile brake hydraulic system so that the hydraulic pressure of the front and rear wheels is close to the idealized braking force distribution. Therefore, before the ABS action is started, the EBD has balanced the effective ground grip of each wheel to prevent the rear wheels from locking up first, improving the balance of braking force and shortening the braking distance of the car.
EBD is actually an auxiliary function of ABS, which can improve the effectiveness of ABS. Therefore, some automotive technical performance has ABS+EBD projects.
