The invention relates to a method for taking up play in a drive system when a change in load occurs. The drive system comprises a drive engine (1), preferably an internal combustion engine, coupled to a drive line (2) in a vehicle, an electric motor (3) which acts on the drive engine (1) and/or the drive line (2) with a driving or braking torque, and which motor (3) is coupled to the drive engine or constitutes a part of the drive line, and a control system (4) for controlling the electric motor (3). The control system (4) sends a pulse to the electric motor (3) when a change in load occurs, a torque pulse taking up play in the drive line (2) before a torque stage from the drive engine (1) begins. The size of the pulse is selected from a matrix stored in a memory (12), depending on the current operating conditions. The invention also relates to an arrangement for implementing the method. <IMAGE> |
