Determining operating state of engine in vehicle with hybrid drive system involves adjusting engine running display device if fuel allocation is on and generator torque exceeds defined value

摘要

The method of determining the operating state of an internal combustion engine in a vehicle with a hybrid drive system involves determining a fuel allocation switch-on/switch-off state, determining a generator torque and adjusting an engine running display device if the fuel allocation is on and the generator torque exceeds a defined value. Independent claims are also included for the following: a vehicle with a hybrid drive system and a hybrid drive system.
