ABSTRACT:
A brake hold control device includes a brake actuator having an electromagnetic valve for holding braking force of a vehicle, two accelerator opening degree sensors for control and for defect detection that detect an accelerator opening degree, and a brake ECU that receives detection signals from the two accelerator opening degree sensors as input. The brake ECU releases braking force when predetermined held-brake release conditions, including accelerator opening degree conditions, for releasing a held brake are satisfied. The accelerator opening degree conditions for releasing a held brake are set such that both of the accelerator opening degrees corresponding to the detection signals from both of the two accelerator opening degree sensors are greater than a predetermined opening degree.
