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.
Claims7
A brake system configured to control a brake circuit that is configured to brake a vehicle, the brake system comprising:
- four or more sensors configured to detect an operation amount of a brake pedal operated by a driver, generate a detection signal corresponding to the detected operation amount, and output the generated detection signal;
- and
- an electronic control unit configured to control the brake circuit based on the operation amounts detected by the four or more sensors, the electronic control unit including
- a first electronic control unit to which three or more sensors of the four or more sensors, excluding one predetermined sensor of the four or more sensors, are connected, and
- a second electronic control unit to which two sensors, which include the predetermined sensor and one common sensor, of the three or more sensors are connected, wherein
- the first electronic control unit is capable of determining whether a sensor in a normal state is present among the three or more sensors based on the respective operation amounts detected by the three or more sensors,
- the second electronic control unit is capable of determining whether both of the two sensors are in a normal state based on the respective operation amounts detected by the two sensors, and
- when the first electronic control unit does not determine that the sensor in the 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 is configured to control the brake circuit based on the operation amount detected by at least one of the predetermined sensor or the common sensor.
