Abstract
An engine is controlled based on a wide-open-throttle operation line connecting a driving point at which the engine outputs the maximum torque in a state where the throttle valve opening degree is maximum, and a non-wide-open-throttle operation line connecting a driving point at which the exhaust state of the engine is improved as compared with the wide-open-throttle operation line. A CD mode or a CS mode is selected to drive hybrid electric vehicle. When CD mode is selected, the use of the wide-open-throttle operation line is prohibited, and a requested driving force corresponding to the state where the throttle valve opening degree is maximum is set based on a compounded torque obtained by summing an engine torque determined based on the non-wide-open-throttle operation line and a motor torque that can be output in accordance with the allowable discharge electric power of the battery, and the driving force is controlled.
