METHOD FOR THE FAILSAFE OPERATION OF A HYBRID VEHICLE FOR INITIATING, IN A CONTROLLED MANNER, A SUBSTITUTE MEASURE ALLOWING AN EMERGENCY OPERATION OF THE VEHICLE AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

A method for the fail-safe operation of a hybrid vehicle having an internal combustion engine, an electric motor, and additional vehicle assemblies. A substitute measure that then still allows the vehicle to be operated under emergency running conditions is initiated if a vehicle assembly fails. A performance quantity that is characteristic of the driving-dynamics situation in which the vehicle finds itself is recorded prior to initiating the substitute measure, and is compared to at least one limit value. The substitute measure is initiated if the limit value is exceeded or not attained. A device which includes a device for implementing such a method is also provided.
