That is, when the driver presses the pressing member 131 provided on the steering wheel 17 to generate the first output signal S1 and transmits it to the controller 133, the controller 133 outputs the first control signal ctrl according to the vehicle speed at which the vehicle is currently traveling. To further control the size of the force of the calipers 19a, 19b, thereby avoiding excessive braking force of the vehicle.

Next, when the driver presses the pressing member 131 provided on the steering wheel 17 again, the pressing member 131 outputs the first output signal S1 to the controller 133 again, so that the driving controller 133 outputs the first control signal ctrl and transmits them separately. To the motors 18a, 18b. The motors 18a and 18b respectively drive the parking actuators 135a and 135b in accordance with the first control signal ctrl to cause the parking actuators 135a and 135b to control the calipers 19a and 19b to disengage from the corresponding disks 21c and 21d.

It should be noted that, in this embodiment, the driver can repeatedly press the pressing member 131 disposed on the steering wheel 17 to cause the controller 133 to control the calipers 19a, 19b of the left and right rear wheels to be tightened or disengaged. action.

Furthermore, as can be seen from the above, in addition to the first output signal S1, the controller 133 can receive information such as the vehicle speed, the wheel speed, or the steering speed of the steering wheel 17 in the present embodiment.

For example, when the driver is driving the vehicle, the vehicle speed, the wheel speed, or the steering wheel 17 steering speed is transmitted to the controller 133, and when an emergency occurs, the driver presses the pressing member located on the steering wheel 17. At 131 o'clock, the controller 133 will output the first output signal S1 according to the pressing element 131 and the vehicle.
