EBD Control

In ABS, electronic control is used so the rear wheel brake hydraulic pressure during braking is regulated by rear wheel control solenoid valves in accordance with the vehicle's rate of deceleration. The front and rear wheel slippages are calculated from the signals received from the various wheel sensors. EBD control is a control system which provides a high level of control for both vehicle braking force and vehicle stability. The system has the following features:

• To shorten the harness wires and enhance data transmission reliability, communication with other ECU is performed over a CAN (Controller Area Network).
• Fail-safe function ensures that safety is maintained.
• Diagnostic function provides improved serviceability.
• Because the system provides the optimum rear wheel braking force regardless of vehicle load and the condition of the road surface, the system reduces the required pedal depression force, particularly when the vehicle is heavily loaded.
• Because the duty placed on the front brakes is reduced, the increases in pad temperature can be controlled during front brake application to improve pad wear.
• Control valves such as the proportioning valve are not required.
