When the magnitude |ω| of a steering angular velocity ω is equal to or greater than a determination angular velocity ωth, an electric motor is estimated to be in a predetermined power use state, and a restriction determination threshold Vonth is set to a first voltage value V1 (S24). When the magnitude |ω| of the steering angular velocity ω is less than the determination angular velocity ωth, the restriction determination threshold Vonth is set to a second voltage value V2 (>V1) (S25). When a state in which a power supply voltage Vx is lower than the restriction determination threshold Vonth continues for a predetermined time t1 (S30: Yes), a power use restriction instruction is output to specific vehicle electrical loads. Thus, power restriction is properly imposed on the vehicle electrical loads, whereby a delay in control of the electric motor is prevented, and excessive imposition of power restriction is prevented.
