Device and method for control of a motor vehicle's propulsion

摘要

The invention relates to a method for automatic disconnection of the propulsion of a motor vehicle (100; 110) by means of a clutch (240) in a power train of the vehicle. The method comprises the steps of continuously determining a prevailing driving force (Fdriv) for propulsion of the vehicle (100; 110), and automatically opening said clutch (240) when said driving force (Fdriv) exceeds a predetermined value (THforce), in order to disconnect the vehicle's propulsion. The invention relates also to a computer programme product containing programme code (P) for a computer (200; 210) to implement a method according to the invention. The invention relates also to a device for automatic disconnection of the propulsion of a motor vehicle (100; 110) by means of the clutch (240) in the vehicle's power train and to a motor vehicle (100; 110) which is equipped with the device.
