DSC (Dynamic Stability Control) is a system that has been installed on BMW, Jaguar, Ford, Mazda, Land Rover, and MINI vehicles. It is based on the anti-lock braking system and improves vehicle stability during driving. It also prevents wheels from slipping. The system enhances handling and safety during maneuvers.
DSC analyzes readings from the yaw rate sensor, lateral and longitudinal acceleration sensors, wheel speed sensors, and the brake pressure sensor. This allows it to calculate the actual direction of the vehicle’s movement. The steering wheel angle and accelerator pedal position are used to assess driver intervention.
If the actual direction of the vehicle’s movement differs from the intended one, the system activates the hydraulic unit. This increases pressure in the brake circuit. The rotational speed of one or more wheels is reduced, allowing the car to return to the intended path. Engine torque can also be adjusted if necessary.
DSC turns on automatically. If needed, it can be deactivated by pressing the button on the center console or in the display settings. This is recommended when driving on loose or soft ground or if snow chains have been installed.
