Abstract
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). The ECU performs control in accordance with the charging state of the battery for running, such that the work rate of an electric pump for cooling the MG(2) is increased when the charging state is higher, and the running mode that uses the MG(2) only is maintained.
Claims4
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 changes a mode of coolant supply to the motor in accordance with a state of charge of a battery for supplying electric power to the motor.
