Abstract:
A hybrid vehicle having a controller controls output torque of an engine and output torque of a generator motor so as to apply requested torque to a drive shaft. The controller performs engine intermittent operation to stop operation of the engine when a given engine operation stop condition is satisfied, and start the engine when a given engine start condition is satisfied. The controller makes an in-cylinder injection valve abnormality determination while causing a total amount of fuel to be injected from an in-cylinder injection valve, and makes a port injection valve abnormality determination while causing the total amount of fuel to be injected from a port injection valve. If at least one of abnormality determinations concerning the in-cylinder injection valve and the port injection valve has not been made, the engine is operated so that the load of the engine falls within a predetermined range.
