Abstract

A vehicle control system includes a brake mechanism and a first power source. The brake mechanism includes: a hydraulic brake provided for a vehicle wheel to suppress rotation of the wheel in accordance with a hydraulic pressure; a hydraulic pressure supply device including a high-pressure source that supplies a high hydraulic pressure, and first and second electromagnetic valves, to supply the hydraulic pressure to the hydraulic brake by controlling the first electromagnetic valve using the hydraulic pressure; and a control device that performs drive assist control by controlling the hydraulic pressure supply device. The first power source supplies power to the brake mechanism. The control device supplies a current to a solenoid of the first electromagnetic valve while suspending supply of a current to a solenoid of the second electromagnetic valve when a voltage of the first power source is lower than a set voltage during the drive assist control.
