  Next, processing performed by the wireless control system 100 will be described using a flowchart. FIG. 14 is a flowchart showing a processing procedure of radio control system 100 according to the first embodiment. First, the operation unit 11 of the wireless transmitter 1 receives an operation (step S1). When the mode switch 11 a of the wireless transmitter 1 is operated, the mode switch 11 a outputs an operation signal including identification information to the signal generator 13. The power supply unit 12 supplies power to the signal generation unit 13 and the wireless transmission unit 14. The signal generator 13 generates a first radio signal based on the operation signal.

  When the operation button 11 b of the wireless transmitter 1 is operated, the operation button 11 b outputs an operation signal including control information to the signal generation unit 13. The power supply unit 12 supplies power to the signal generation unit 13 and the wireless transmission unit 14. The signal generator 13 generates a second radio signal based on the operation signal. The wireless transmission unit 14 transmits the generated first wireless signal or second wireless signal (step S2).

  The radio reception unit 23 of the control device 2 receives the first radio signal or the second radio signal (step S3). When the radio reception unit 23 receives the first radio signal or the second radio signal, the ECU 21 determines whether or not the first radio signal has been received (step S4).

  When the ECU 21 determines that the first wireless signal has been received (S4: YES), the image corresponding to the first wireless signal received by the wireless receiving unit 23 from the storage unit 22 storing the image corresponding to the first wireless signal. Is read (step S5). The ECU 21 outputs the read image to the display unit 24 (step S6). ECU21 specifies the vehicle equipment 3 corresponding to a 1st radio signal (step S7). ECU21 memorize | stores the specified vehicle equipment 3 in the memory | storage part 22 (step S8), and ECU21 complete | finishes a process.

  When it is determined that the ECU 21 has received the second radio signal (S4: NO), the in-vehicle device 3 specified by the ECU 21 is read from the storage unit 22 (step S9). The ECU 21 determines whether or not the in-vehicle device 3 specified by the ECU 21 is stored in the storage unit 22 (step S10). When the ECU 21 determines that the in-vehicle device 3 specified by the ECU 21 is not stored in the storage unit 22 (S10: NO), the ECU 21 ends the process. When the ECU 21 determines that the in-vehicle device 3 specified by the ECU 21 is stored in the storage unit 22 (S10: YES), the ECU 21 controls the in-vehicle device 3 specified by the ECU 21 based on the second radio signal. (Step S11), ECU21 complete | finishes a process.

  When receiving the first wireless signal, the control device 2 reads an image corresponding to the first wireless signal from the storage unit 22 and outputs an image corresponding to the first wireless signal to the display unit 24. As a result, the display unit 24 can display a variety of operation contents.

  Moreover, the control apparatus 2 can reduce the wire harness between a multifunction switch and ECU21 by transmitting a radio | wireless directly to ECU21 not via a multifunction switch. For this reason, the radio control system 100 according to the present invention simplifies the wiring work of the wire harness at the time of vehicle manufacture, and can reduce the vehicle cost. In addition, the wireless control system 100 according to the present invention can reduce the weight of the vehicle 5 by reducing the wire harness.

  Moreover, the control apparatus 2 outputs the figure or character which shows the operation method of the vehicle equipment 3 specified by ECU21 based on the 1st radio signal in association with the button image 22d imitating the operation button 11b. As a result, the user can know the operation method of the operation button 11b by viewing the image output on the display unit 24 and associating the graphic or character indicating the operation method with the button 111 to the button 116. For this reason, it becomes easy for the user to determine the operation content of the operation button 11b.

  The wireless transmitter 1 can be detachably attached to the seat 6, the steering wheel 7, or the display unit 24. As a result, the convenience of the wireless transmitter 1 is improved, and the possibility of the wireless transmitter 1 being lost can be reduced.
