CONTROL DEVICE FOR VEHICLE

摘要

A vehicle control device includes a battery, a boost converter connected to the battery, for boosting battery voltage, a second inverter connected to the boost converter for carrying out direct current/alternating current conversion, a second MG connected to the second inverter, for outputting drive force, and an SOC sensor for detecting charged state of the battery. The control section, when the SOC that has been detected by the SOC sensor exceeds a first threshold value, raises the output voltage of the boost converter compared to when the SOC is below the first threshold value. In this way it is possible to sufficiently utilize regenerative braking and braking without any unpleasant feeling is possible.

主权项

1. A control device for a vehicle, comprising:
a battery; a boost converter connected to the battery, for boosting battery voltage; an inverter, connected to the boost converter, for carrying out DC/AC conversion on output of the boost converter; a motor generator, connected to the inverter, for outputting drive force; a charge state detection section 4 detecting charged state of the battery; and a control section for raising output voltage of the boost converter when the charge state that has been detected by the charge state detection section has exceeded a first threshold value, compared to when the charge state is the first threshold value or less.
