Abstract: To a first electronic control unit, three or more sensors excluding one predetermined sensor are connected. To a second electronic control unit, two sensors, which include one common sensor, of the three or more sensors, are connected. When the first electronic control unit does not determine that a sensor in a normal state is present among the three or more sensors, and the second electronic control unit determines that both of the two sensors are in the normal state, the electronic control unit controls the brake circuit based on the operation amount detected by at least one of the predetermined sensor or the common sensor.

Abstract: A brake device includes a brake pedal, a pedal operation detection section, a tank section, an actuator, a master cylinder, a brake fluid path and a reaction force generating section. The master cylinder includes a cylinder section that forms a storage chamber for storing brake fluid and a piston rod that connects to the brake pedal and pushes out the brake fluid stored in the storage chamber and discharges the brake fluid to an outside of the cylinder section by moving a distance corresponding to an amount of operation of the brake pedal. The brake fluid flow path guides the brake fluid discharged from the storage chamber by being pushed out by the piston rod to the tank section. The reaction force generating section includes an elastic member that generates a reaction force on the brake pedal by elastically deforming according to the amount of operation of the brake pedal.
