Abstract:
1. An in-vehicle control device comprising: a first control unit mounted on a vehicle that performs first control to control an output pressure of a master cylinder for braking; a second control unit mounted on the vehicle that performs second control to control a wheel pressure control mechanism for braking; first and second sensors for measuring the output pressure of the master cylinder, and a transmission channel for communicating information between the first control unit and the second control unit, wherein: an output from the first sensor is taken in and used for the first control by the first control unit; an output from the second sensor is taken in and used for the second control by the second control unit; the first control unit repeatedly performs diagnosis of the first sensor; the second control unit repeatedly performs diagnosis of the second sensor; the first control unit and the second control unit receive each a result of measurement of the output pressure of the master cylinder measured by each other through the transmission channel; when the first control is being performed, the first control unit does not perform the diagnosis of the first sensor; and when the first control is performed while the diagnosis of the first sensor is being performed, the first control unit performs the first control based on the measurement value of the output pressure of the master cylinder measured by the second sensor and received from the second control unit through the transmission channel instead of the measurement value of the output pressure of the master cylinder measured by the first sensor.
