System Description

VDC


System Description

- Vehicle Dynamics Control system detects driver's steering operation amount and brake pedal travel from steering angle sensor and pressure sensor. Using information from yaw rate/side G sensor and wheel sensor, VDC judges driving condition (conditions of under steer and over steer) to improve vehicle driving stability by controlling brake application to 4 wheels and engine output.
- Brake force control function at booster fail detects driver's brake operations with the pressure sensor, judges a dysfunction in brake power of brake booster by using information from the vacuum sensor, and assists braking force by controlling brakes of four wheels.
- Brake force control function at braking hard detects driver's brake operations with the pressure sensor, judges a brake booster's maximum brake power function by using information from the vacuum sensor, and enhances more powerful braking force by controlling brakes of four wheels.
- During VDC operation, it informs driver of system operation by flashing SLIP indicator lamp.
- Brake force control function at booster fail alerts the driver to the dysfunction in brake power by turning on the brake warning lamp during brake force control function at booster fail operation.
- Electrical system diagnosis by CONSULT-III is available.
