DEVICE AND METHOD FOR PERFORMING A GEAR CHANGE OF A VEHICLE

摘要

The invention relates to a method for executing a gear shift step in a motor vehicle (100; 110) comprising an engine (220) and an automated manual transmission incorporating a clutch (230) and a gearbox (240), which method comprises the steps, during a gear shift procedure, of: - controlling a torque (Tc) in said clutch (230) in order to make it possible for said gear shift step to take place before a target speed (rpm*) of the engine (220) is reached; and, when said clutch (230) has stopped sliding, of controlling a torque (Te) of the engine (220) on the basis of the torque (Tc) in the clutch (230). The invention relates also to a computer program product comprising program code (P) for a computer (200; 210) for executing a method according to the invention. The invention relates also to a device for executing a gear shift step in a motor vehicle (100; 110) comprising an engine (220) and an automated manual transmission incorporating a clutch (230) and a gearbox (240), and to a motor vehicle that is equipped with the device.
