Next, with reference to FIG. 9, the functions of the communication section 114 will be explained. The ABS unit 60 includes a communication section 114. The communication unit 114 communicates with an external device. The external device coordinately controls the controlled device in connection with the control of the braking force.

As shown in FIG. 9, in one example, the communication unit 114 is communicably connected to the electric auxiliary drive device 58, the electric transmission devices 44 and 46, and the warning light 116 by wire or wirelessly. The warning light 116 lights up or flashes while the ABS unit 60 is in operation to notify that the ABS unit 60 is in operation.

In one example, the communication unit 114 is connected to a mobile terminal device 118 such as a smartphone so as to be able to communicate wirelessly. The communication unit 114 may be communicably connected to another terminal device such as a personal computer by wire or wirelessly.

By transmitting a predetermined command to the communication unit 114, the mobile terminal device 118 controls the operation of the electric auxiliary drive device 58 while the ABS unit 60 is in operation, the operation of the electric transmission devices 44 and 46, and the notification operation by the warning light 116. You can set permissions and prohibitions. The mobile terminal device 118 can change the braking force and intervention deceleration settings of the ABS unit 60 by transmitting a predetermined command to the communication unit 114.

The communication unit 114 sets permission or prohibition of various operations by transmitting predetermined commands received from the mobile terminal device 118 to the corresponding electric auxiliary drive device 58, electric transmission devices 44, 46, and warning light 116. . The communication unit 114 transmits predetermined commands received from the mobile terminal device 118 to the corresponding electric auxiliary drive device 58, electric transmission devices 44 and 46, and warning light 116, thereby setting permission and prohibition of various operations. change.

Communication unit 114 transmits the operating state of ABS unit 60 to electric auxiliary drive device 58, electric transmission devices 44 and 46, and warning light 116. Electric auxiliary drive device 58, electric transmissions 44, 46, and warning light 116 operate according to settings during operation of ABS unit 60.
