Outline of EBD Control Function
1) General
The distribution of the brake force, which was performed mechanically in the past, is now performed
under electrical control of the skid control ECU, which precisely controls the braking force in accordance
with the vehicle's driving conditions.
2) Front/Rear Wheels Brake Force Distribution
If the brakes are applied while the vehicle is moving straight forward, the transfer of the road reduces
the load that is applied to the rear wheels. The skid control ECU determines this condition by way of the
signals from the speed sensors, and the brake actuator regulates the distribution of the brake force of the
rear wheels to optimally control.
For example, the amount of the brake force that is applied to the rear wheels during braking varies
whether or not the vehicle is carrying a load. The amount of the brake force that is applied to the rear
wheels also varies in accordance with the extent of the deceleration.
Thus, the distribution of the brake force to the rear is optimally controlled in order to effectively utilize
the braking force of the rear wheels under these conditions.

3) Right/Left Wheels Brake Force Distribution (During Cornering Braking)
When the brakes are applied while the vehicle
is cornering, the load that applied to the inner
wheel decreases and the outer wheel
increases.
The skid control ECU determines this
condition by way of the signals from the speed
sensors, and the brake actuator regulates the
brake force in order to optimally control the
distribution of the brake force to the inner
wheel and outer wheel.
