Method for operating drive device, particularly hybrid drive device, involves varying conveying capacity of coolant pump depending on current operating temperature or current driving torque of electric machine

摘要

The method involves varying the conveying capacity of a coolant pump (9) depending on a current operating temperature or a current driving torque of an electric machine (4). The conveying capacity is varied with reference to an energy storage (8) that is electrically connected with the coolant pump. An independent claim is also included for a drive device with a current sensor.
