Estimating the term…
In a vehicle equipped with a motor generator and a starter, if an ignition key has been switched from OFF to ON, preferably an engine is started by using the starter. However, if the temperature T of the engine is high (B≦T), the engine is started by the motor generator. When the engine is restarted after automatic stop thereof, preferably the engine is started by using the motor generator. However, if the temperature T of the engine is low (T≦A), the engine is started by using the starter. The engine is started by suitably selecting between the starter and the motor generator, whereby it becomes possible to improve responsive characteristics and startability and abate oscillatory noise.
A vehicular engine starting control apparatus for a vehicle having an engine which outputs power to a drive shaft of the vehicle, a motor-generator which inputs power to and outputs power from a power transmission path that extends from an output shaft of the engine to the drive shaft, and a starter which is coupled to the output shaft of the engine, the control apparatus comprising:
