This function activates mechanical clamping if the vehicle must additionally be secured for hydraulic hold functions (Automatic Hold, Active Cruise Control with Stop & Go function), for example if the driver leaves the vehicle. The DSC control units detects if the driver leaves the hydraulically secured vehicle (CAN messages, e.g. seat belt buckle contact, door contact). The DSC then requests that the parking brake engage additional mechanical braking.
