Abstract:
1. A control device for a hybrid vehicle having 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 temperature, the control device comprising: a detector configured to detect a state of charge of a battery arranged to supply power to the motor via an inverter; and a processor configured to set a direct current voltage supplied from the battery to the motor, the processor setting the direct current voltage to a first voltage value in response to the detector detecting the state of charge as a first state of charge value while the vehicle is running in the running mode, and the processor setting the direct current voltage to a second voltage value higher than the first voltage value in response to the detector detecting the state of charge as a second state of charge value lower than the first state of charge value while the vehicle is running in the running mode, wherein the processor sets the direct current voltage to the first voltage value, which is lower than the second voltage value, and also increases the threshold temperature in response to the detector detecting the state of charge as the first state of charge value, which is higher than the second state of charge value.
