DSC (Dynamic Stability Control) is a system used in vehicles installed by BMW, Jaguar, Ford, Mazda, Land Rover and MINI. It is based on the anti-lock braking system and improves vehicle stability while driving. It also prevents wheel spin and improves handling and safety when manoeuvring.
How the DSC works
Here, the DSC analyzes the measured values of the yaw rate sensor, as well as the lateral and longitudinal acceleration sensors, as well as the wheel speed sensors and the brake pressure sensor. In this way, the actual direction of movement of the vehicle can be determined. The steering wheel angle and also the position of the accelerator pedal are used to evaluate the driver's influence.
If the actual driving direction differs from the intended one, the system activates the hydraulic unit here. Because this increases the pressure in the brake circuit and the speed of one or more wheels is reduced, which allows the car to return to the intended direction of travel. If necessary, the motor torque can be adjusted as needed.
DSC is switched on automatically. If necessary, it can be deactivated by pressing a button on the center console or in the display settings. This is recommended when driving on loose or soft surfaces or with snow chains.
