CONTROL DEVICE FOR HYBRID VEHICLE

摘要

A control device for a hybrid vehicle, including a mode whereby the vehicle runs using a motor only, and a mode whereby the vehicle uses both the motor and an engine. When the motor temperature of an MG(2) exceeds a threshold temperature, an ECU moves from a running mode that uses the MG(2) only, to a running mode that limits the load on the MG(2). When the charging state of a battery for running exceeds a threshold value, the ECU performs control such that in addition to the system voltage for driving the MG(2) being reduced, the threshold temperature is increased, and the running mode whereby only the MG(2) is used is maintained.

1. A control device for a hybrid vehicle comprising an engine and a motor,
the vehicle having a running mode in which the vehicle runs with a motor load being limited when a temperature of the motor exceeds a threshold, wherein the vehicle comprises a battery for supplying power to the motor via an inverter, and changes voltage to be supplied to the motor by the battery in accordance with a state of charge of the battery.
