上記電動機の温度が所定温度よりも低いとき、上記電動機が回転しないように上記電動機に上記パージポンプを駆動する際に流す電流よりも大電流を流す通電動作と、極低回転で上記電動機を回転させる回転動作と、を交互に繰り返す上記電動機の暖機制御を実施する車両の制御方法。A method of controlling a vehicle in which an electric motor having a rotor shaft supported on grease-lubricated rolling bearings drives a purge pump for purging a canister, comprising:
When the temperature of the electric motor is lower than a predetermined temperature, an energization operation is performed to pass a current larger than the current that is applied to the electric motor to drive the purge pump so that the electric motor does not rotate, and the electric motor is rotated at an extremely low speed. A control method for a vehicle that performs a warm-up control of the electric motor that alternately repeats a rotation operation to rotate the motor.
上記電動機の暖機制御の実施中は、上記パージ制御弁を閉じる請求項１または３に記載の車両の制御方法。The evaporated fuel in the canister is introduced into an intake passage of an internal combustion engine mounted on a vehicle through a purge passage having a purge control valve,
4. The method of controlling a vehicle according to claim 1, wherein the purge control valve is closed during execution of warm-up control of the electric motor.
