The desired value of angular acceleration is calculated by the electronic brake control unit according to the following inputs:
- Steering angle sensor signal.
- Vehicle speed.
- longitudinal acceleration.
The difference between the desired angular acceleration and the actual yaw of the vehicle is the amount needed to measure oversteer or understeer. When such a difference is detected, the electronic brake control unit tries to stabilize the movement by braking one or more wheels. The degree of pressure on the brake pedal is constantly changing, so the pressure in the brake circuits is also constantly adjusted. In addition, if it is necessary to slow down the vehicle to maintain directional stability, the engine torque can be reduced.
The activation of the stability control system usually occurs during sharp turns in aggressive driving. When braking while the system is activated, the brake pedal may pulsate.
The stability control system can be manually disabled or enabled by pressing the traction control switch for 5 seconds.
