Abstract:
1. A method of carrying out a shift operation, when one of an electric machine has failed or an energy accumulator is full, in a parallel hybrid vehicle having an automated transmission with traction force interruption during hybrid operation, the method comprising the steps of: during an upshift, generating torque with the electric machine for synchronizing a transmission input by connecting a power inverter, which is actuated with an active short-circuit, to the electric machine; and braking an internal combustion engine, for load reduction, by actuating the power inverter with an active short-circuit and which is connected to the electric machine, if the internal combustion engine is coupled to the electric machine during the load reduction, to synchronize a transmission input with a torque generated by the electric machine.
