Abstract

A method and an arrangement for operating a drive motor of a vehicle are suggested. A resulting desired torque for controlling the drive motor is pregiven in dependence upon the driver command torque and additional desired torque quantities. To limit the resulting desired torque, a motor minimum torque is provided which is derived from the lost torques and is dependent upon rpm.
