Abstract
A method for preventing undesired movements of a motor vehicle combination (100) including a tractor vehicle (110) and a towed vehicle (112), where the tractor vehicle (110) has a parking brake system (280), the vehicle combination (100) has at least one electronically activable service brake system (270; 275) and is provided with movement detectors (210, 220, 230, 240, 250) and the parking brake system (280) is activated during desired standstills of the vehicle combination (100). The method includes the steps of:—continuously detecting (s320) movements of the vehicle combination (100) relative to a running surface on which the vehicle combination (100) is at the time; and—responding to detected movements of the vehicle combination by automatically activating (s330) service brake action of the electronically activable service brake system (270; 275). Also, a computer program product has program code (P) for implementing the method. A system for preventing undesired movements of a motor vehicle combination (100) and a motor vehicle combination (100) equipped with the system are disclosed.
