A method for operating a brake system. A brake request signal characterizing a brake request is generated by actuating a positioner system of an actuating circuit, and a setpoint brake pressure required in an active circuit is ascertained based on the brake request signal. An actual brake pressure is set in the active circuit according to the setpoint brake pressure using a pressure generation device by moving a displacement piston using an electric motor to actuate a wheel brake coupled with the active circuit. Under the condition that the brake request signal is constant over a predefined period of time, a pressure modulation is carried out, which includes setting the actual brake pressure in the active circuit to a value that is greater than the setpoint brake pressure, and lowering the actual brake pressure by moving the displacement piston using the electric motor until the setpoint brake pressure is reached.

An accelerator device includes a pedal pad and a strain gauge. When a driver of a vehicle having the accelerator device depresses the pedal pad, the pedal pad is deformed in a direction of a blank arrow. The strain gauge senses the displacement amount of the pedal pad in the direction of the blank arrow and outputs an electric signal, which corresponds to the displacement amount, to an outside as the depression amount of the accelerator device. When the driver removes a foot from the pedal pad, the pedal pad returns to a state of the pedal pad that is not depressed by the driver. Therefore, it is possible to limit occurrence of that the depression amount of the pedal pad becomes an unintended value due to, for example, catching of the pedal pad by a floor mat. As a result, the accelerator device can reliably sense the depression amount.

A system for parking control of a vehicle in which a transmission parking configuration is omitted is provided. The system includes a shift by wire device that requests a parking control of the vehicle when a parking stage is input by an operation of a driver. An electronic parking brake operates a brake installed on a drive wheel via a relay which is connected to be in a parking brake state when the electronic parking brake receives the parking control request from the shift by wire device. The shift by wire device switches the relay to directly operate the brake to be in the parking brake state when the shift by wire device receives a failure event, which indicates that a normal operation of the electronic parking brake is impossible, from the electronic parking brake.
