METHOD AND DEVICE FOR PLAUSIBILITY CHECKING OF A DRIVING TORQUE APPLIED BY AN ELECTRICAL ENGINE IN A HYBRID DRIVE OF A MOTOR VEHICLE

摘要

The invention relates to a method for plausibility checking of a driving torque applied by an electrical engine in a hybrid drive of a motor vehicle, wherein the motor vehicle is driven by the electrical engine (1) and/or an internal combustion engine (3), wherein it is inspected whether the driving torque (MdEres) applied by the electrical engine (1) is precisely determined. In order to ensure that the operating strategy is carried out correctly during driving operation of the motor vehicle and that a load point shift functions reliably in the drive train, according to the invention the driving torque (MdEres) applied by the electrical engine (1) is evaluated in respect of the accuracy thereof by means of a drag torque (MdVSchlepp) generated during an overrun cut-off by the internal combustion engine (3).
