Control device for compensating gearwheel clearance of gear wheels of e.g. single stage gear box in electric car, has drive shaft driven by motor, where rotation torque is controlled based on output signal and delivered from motor to shaft

摘要

The device (1) has a drive shaft (AW1) driven by a drive motor (9) i.e. electric drive motor, where rotational speed of the drive shaft is transferred to rotation speed of another drive shaft (AW2). A controller (2) i.e. PID controller, compares rotation speed alteration of the former drive shaft with a predetermined maximum permissible rotation speed alteration of the former drive shaft for the computation of a controller output signal (RA). A rotation torque delivered from the drive motor to the former drive shaft is controlled in dependence on the controller output signal. Independent claims are also included for the following: (1) a powertrain for a vehicle (2) a method for compensating a gearwheel clearance of gear wheels of a gear box.
