Abstract
An engine operation controller for a hybrid electric automobile is equipped at least with a motor and an engine. The engine operation controller is provided with a speed detection section for detecting the speed of the vehicle, a control section for controlling operation of the engine, and a decision section for deciding whether or not a stop of the vehicle is a stop at a stopping place. If it is detected by the speed detection section that the speed is less than a predetermined value, operation of the engine is prohibited by the control section. Furthermore, a delay section is provided for delaying removal of the operation prohibition of the engine when it is decided by the decision section that the stop of the vehicle is a stop at a stopping place.
