The stabilization system controls the vehicle's dynamics in extreme conditions, such as when cornering at high speed. The risk of the vehicle skidding or drifting is significantly reduced under all possible road surface conditions.
Normally the stabilization system is always on. Only in certain exceptional cases, when wheel slip is desired, it is preferable to turn off the system.
Operation of the electronic stabilization system
The electronic stabilization system integrates the anti-lock braking system and both traction control systems. In addition to the information required for these systems, the electronic stabilization system control unit requires additional data supplied by highly sensitive sensors. The speed of the body movement around the vertical axis of the car, the magnitude of acceleration in the transverse plane, the pressure in the brake drive system and the angle of rotation of the steering wheels are measured.
Based on the data on the angle of rotation of the steering wheels and the speed of the car, the direction in which the driver intends to move is determined and it is constantly compared with the actual behavior of the car. If these factors do not agree, when the car begins to skid or drift, the stabilization system automatically brakes a certain wheel.
By means of the forces that arise when the desired wheel is braked, the car returns to a state of dynamic stability. When the car oversteers (tendency for the rear of the car to skid) braking action is applied to the front wheel, outside the turn, in case of understeer (tendency for the front of the car to drift outward around a turn) the rear inner wheel is braked.
