METHOD AND DEVICE FOR OPERATING A HYBRID VEHICLE

摘要

A method (110), a device (10), and a powertrain (70) are provided for the safe operation of a hybrid vehicle (20). The hybrid vehicle has at least one first (30) and one second (40) drive assembly. The drive assemblies in each case drive the hybrid vehicle, alone or jointly in a hybrid type of operation. The first drive assembly is operated using fuel from a fuel tank (50). An amount of fuel in this fuel tank is monitored. If the amount of fuel is smaller than a specifiable value, then a safety operation of the hybrid vehicle is activated. During the safety operation, the output of the second drive assembly is reduced if the hybrid vehicle is driven using a type of operation which negatively influences the driving dynamics of the hybrid vehicle in the case of a failure of the first drive assembly.

1. A method (110) of operation of a hybrid vehicle (20), wherein the hybrid vehicle (20) has a first (30) and a second (40) drive assembly,
wherein the drive assemblies (30, 40) in each case drive the hybrid vehicle (20), alone or jointly in a hybrid type of operation, wherein the first drive assembly (30) is operated with fuel from a fuel tank (50) and an amount of fuel in the fuel tank (50) is monitored (120, 160), wherein a safety operation (130) of the hybrid vehicle is activated if the amount of fuel is smaller than a specifiable value (150, 170), characterized in that the output of the second drive assembly (40) is reduced during the safety operation (130) if a type of operation is being used which negatively influences the driving dynamics of the hybrid vehicle (20) in the case of a failure of the first drive assembly (30).
