Vehicle starting apparatus

摘要

There is provided a vehicle starting apparatus that reduces vibration of an engine caused when the engine starts so that vibration of the vehicle can be decreased. A vehicle starting apparatus according to the present invention is provided with an engine starting apparatus that starts an engine mounted in a vehicle, wherein before the engine is ignited, the engine starting apparatus makes a cranking rotation speed of the engine lower than a rotation speed corresponding to the resonance frequency of the engine, and after the engine has been ignited, the engine starting apparatus increases the rotation speed of the engine up to a rotation speed that is the same as or higher than said rotation speed corresponding to the resonance frequency.

主权项

1. A vehicle starting apparatus comprising:
an engine starting apparatus that starts an engine mounted in a vehicle, wherein the engine starting apparatus includes: a rotating electric machine; an inverter; and a control apparatus that controls the rotating electric machine, the control apparatus configured to: calculate a target rotation speed of the rotating electric machine which cranks the engine at a rotation speed that is lower than a rotation speed corresponding to a predetermined resonance frequency of the engine, control the rotating electric machine to crank the engine at the target rotation speed before the engine is ignited and until the control apparatus determines the engine has been ignited due to the cranking at the target rotation speed, and after the engine has been ignited, control the rotating electric machine to increase the rotation speed of the engine to be more than said rotation speed corresponding to the predetermined resonance frequency of the engine.
