The invention provides a vehicle (V) capable of suppressing temperature rise of a sub-drive unit. In a vehicle (V), a voltage control unit (VCU) outputs a boosted voltage obtained by boosting an output voltage of a battery (BAT). The main drive unit (DU1) has an engine (ENG) and a main drive motor (MOT1) driven by electric power from the voltage control unit (VCU), and outputs a main drive force for driving the front wheel (FWR) by means of at least one of the engine (ENG) and the main drive motor (MOT1). The secondary drive unit (DU2) has a secondary drive motor (MOT2) driven by electric power from the voltage control unit (VCU), and outputs a secondary drive force for driving the rear wheel (RWR). When the main drive unit (DU1) outputs the main drive force including the drive force of the engine (ENG), the control unit (CTR) increases the boost voltage when the temperature of the sub-drive unit (DU2) is equal to or greater than a predetermined value than when the temperature of the sub-drive unit (DU2) does not reach the predetermined value or greater.
本发明提供一种能够抑制次驱动单元的温度上升的车辆(V)。在车辆(V)中,电压控制部(VCU)输出对蓄电池(BAT)的输出电压进行升压后的升压电压。主驱动单元(DU1)具有发动机(ENG)和由来自电压控制部(VCU)的电力驱动的主驱动马达(MOT1),通过发动机(ENG)和主驱动马达(MOT1)中的至少一方输出驱动前轮(FWR)的主驱动力。次驱动单元(DU2)具有由来自电压控制部(VCU)的电力驱动的次驱动马达(MOT2),并且输出驱动后轮(RWR)的次驱动力。当主驱动单元(DU1)输出包含发动机(ENG)的驱动力的主驱动力时,在次驱动单元(DU2)的温度为规定值以上的情况下,与次驱动单元(DU2)的温度未达到规定值以上的情况相比,控制单元(CTR)增加升压电压。
