What is?
In the instant brake of the high-speed friction value calculated four tires, and then adjusted to match the braking force and frictional force, to ensure the smooth and safe vehicle.
2
what’s the use?
during braking, road conditions may be applied to the four wheels according to different braking forces, and constantly adjusted to avoid slipping, rollover, etc., to ensure safe and smooth vehicle.

advantages
greater sense of vibration noise can be reduced when the ABS is working, without increasing any hardware configuration.

Technology Principle
is usually expressed in English EBD, full name ElectronicBrakeforceDistribution, i.e., electronic brake force distribution apparatus. In the case where the emergency brake wheel lock, EBD before ABS operation has been balanced by the effective surface of each of the wheel grip, can beTo prevent drift and drift and reduce automobile braking distance. EBD is actually a secondary function of ABS, it can be improved to improve the effectiveness of ABS. So on the safety indicators, the performance of the car’s addition of “ABS + EBD”.
When the brakes, four brake calipers of the vehicle wheels will actions to stop the vehicle. However, due to road conditions have variation, together with the transfer of the center of gravity of the vehicle deceleration, the grip between the four wheels and the ground will be different. The average conventional brake system will assign the brake master cylinder to power four wheels. From the foregoing, this distribution does not meet the efficiency in the use of brake force. EBD system will be invented to make the best of the brake force application.

To develop
Some models do not turn but called called EBD brake control (CBC) (CurveBrakeControl ). In fact, the role of EBD almost. Although at the time of the brakes, anti-lock brakes to prevent the wheels from locking and helps maintain steering control, but depending on the environment, if the emergency brake when cornering, the car will still be in danger of sliding.
during cornering braking, anti-lock brake system with the CBC work, control the pressure of each wheel brake cylinder, thereby reducing the risk of oversteer and understeer. In this way, to achieve the optimal brake force distribution, so as to ensure stability when cornering brake. Turning the signal from the ABS brake control pressure in each brake control, even when the driver applies a braking force to one half, but also can obtain an optimal braking effect. Non-automotive CBC usually continue straight ahead at half-bent brake. Dynamic stability control system continuously monitors steering angle and throttle position to determine whether the turning movement caused understeer or oversteer. Then, the car will reduce engine power and selectively braking individual wheels, causing the car back on the right track.
When the car is rolling at a speed of about 100km in the mountainsFleet of Foot on the high-speed corners, we can carefully observe the car vehicle dynamics when cornering and out of the corners. When the car turns, due to the transfer of the center of gravity so that the outside of the vehicle body sinks, suspension compression pressure, the car roll exhibits signs. As a result of the active air suspension, the control electronics will automatically sink to the outside of the suspension is about to make it no longer pressure drop. The result is obvious and very effective, is to significantly reduce body roll and increase driving stability, so that passengers sit at ease and comfortable. Indeed, at high speeds active suspension function is to stabilize the body, preventing excessive rapid transfer of the center of gravity. It sedimentation and active body (decrease 23mm) acting together. Lower center of gravity makes the car after the Active Body settlement, plus suspension of cooperation in the dynamic traffic, better overall performance.
