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.
1. What is the use braking power distribution
during braking, the braking force may be applied on four different wheels according to road conditions, and continuously adjust to avoid slipping, rollover, etc., to ensure that vehicles safe and stable.
2. Advantages of the braking force distribution
can be larger when the sensing noise reduction ABS work, without adding any hardware configuration.
3. The technical principle of the braking force distribution
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 and lateral drift can be prevented, and shortening vehicle braking distance.
EBD is actually accessibility ABS, which can improve improve the effectiveness of ABS.
so in safety indicators, the performance of the car the addition of “ABS + EBD”.
In the brake when the four brake calipers of the vehicle wheels will actions to stop the vehicle.
However, due to road conditions have variation, coupled with the transfer of the center of gravity of the vehicle deceleration, the grip between the four wheels and the ground will vary.
The conventional braking system will be assigned the average power of the brake master cylinder to four wheels.
From the foregoing, such a distribution does not meet effective use of the braking force.
EBD system of the invention will be to make the best of the braking force applied.
4. Expand related braking force distribution
Some models do not turn but called called EBD brake control (CBC) (CurveBrakeControl).
In fact, the role of EBD almost.
Although during braking, anti-lock brakes to prevent the wheels from locking and can help maintain the steering control, but depending on the environment, if the emergency braking during cornering, the car is still 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.
cornering brake control signal from the ABS control use pressure in each brake applies a braking force to the driver even if half, can be obtained optimum braking effect.
Non-CBC cars usually continue straight ahead when the brake semi-curved.
Dynamic Stability Control system continuously monitoring the steering angle and the throttle position, determining whether the operation of turning oversteer or understeer initiator.
Then, the car will reduce engine power, and selectively braking each of the wheels, so that car back on the right track.
When the car at a speed of about 100km Fleet of Foot-speed rolling curve on the mountain, we can carefully observe the car body during cornering and the dynamic curved.
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.
RealOn occasion, the active suspension function at high speeds is the stability of the vehicle body, preventing excessive rapid transfer of the center of gravity.
It is the active body settling (falling 23mm) acting together.
After the active command to reduce the car body center of gravity settling, plus suspended in the dynamic driving in cooperation, better overall performance.
