Method for controlling the operating response of a hybrid drive of a vehicle
First Claim
1. A method for controlling an operating behavior of a hybrid drive of a vehicle, the hybrid drive including an internal combustion engine and at least one electric motor, and at least one of a drive shaft of the internal combustion engine and a drive shaft of the at least one electric motor being operatively connectible to a drive train of the vehicle, the method comprising:
- providing control signals for controlling the internal combustion engine and the at least one electric motor, wherein the control signals are based on a negative torque request and a transmission setting of the transmission, and wherein the control signals request a specified torque for transmission to the drive train; and
setting a vehicle-speed-dependent drag torque characteristic curve for the hybrid drive by the control of the hybrid drive, in such a way that the magnitude of the drag torque is independent of the speed of the internal combustion engine and the occurrence of step-wise torques in response to shifting down of the transmission is prevented.

Abstract
A method of controlling the operating response of a hybrid drive of a vehicle is described, the hybrid drive having an internal combustion engine and at least one electric motor as the drive motors, and the drive shafts of the drive motors being mechanically linkable to a drive train of the vehicle. A drag torque characteristic curve for the hybrid drive is established by targeted activation of the at least one electric motor.
