Further, 4 receives the mode switching signal and switches the control mode from the first state to the second state, and automatically sets the control mode to the first state on the condition that a predetermined time has elapsed and / or the vehicle travels. It is a mode switching unit for returning.

Reference numeral 5 denotes a first control circuit section which responds to an operation signal of the operation switch 2 when the mode switching section 4 is in the first state, and in the embodiment, it is a wiper control circuit. is doing. Reference numeral 6 denotes a second control circuit unit that responds to an operation signal from the operation switch 2 when the mode switching unit 4 is in the second state, and in this embodiment, it is composed of a posture control circuit such as a tilt handle. However, the present invention is not limited to this.

Each of the above configurations will be described in detail. First, the switching signal generator 1 is composed of a push switch provided at the tip of the wiper control lever 71 of the combination switch device 7 as shown in FIGS. 3 and 4, and the push knob 11 is moved in the direction of arrow A. When operated, the movable contact piece 12 provided on the support portion 29 contacts the fixed contact 13.

The operation switch 2 is composed of a rotary switch provided at the tip of the wiper control lever 71 in the same manner as described above. When the rotary operation knob 21 is operated to rotate in the directions of arrows B and C, The disk 22 engaged with the rotary operation knob 21 via the protrusion 22a rotates, and the movable contact piece 23 switches and contacts the fixed contacts 25, 26, 27 and 28 provided on the pole board 24. The operation switch 2 and the switching signal generating section 1 are electrically connected to the mode switching section 4 provided in the main body of the combination switch device 7 via the wire 72 embedded in the wiper control lever 71.

Further, the vehicle stop detection unit 3 is configured to detect that the vehicle is in a stopped state like a vehicle speed sensor, a parking brake switch, an inhibitor switch, etc., and is connected to the mode switching unit 4.

The mode switching unit 4 is composed of a microcomputer or a logic circuit programmed to execute the functions of the flowchart shown in FIG. 2, and has a first control circuit unit 5 and a second control circuit unit. Connected to 6. The mode switching unit 4 is provided on the printed circuit board 73 of the combination switch device 7.

Further, the first control circuit section 5 and the second control circuit section 6 are connected to each other by a relay, a power transistor or the like, and are connected to the motors 51, 52, 61 and 62. In addition, 8 is an ignition switch.

Next, the operation will be described based on the flowchart shown in FIG. First, in step 101, it is determined whether or not the ignition switch 8 is turned on, and if YES, the process proceeds to step 102.

In step 102, it is determined whether or not the vehicle stop detection unit 3 derives a vehicle stop detection signal indicating that the vehicle is in a stopped state. If YES, go to step 103, and if NO, go to step 108. move on.

In step 103, it is judged whether or not the switching signal generator 1 has derived the mode switching signal, and if YES, the procedure goes to step 104, and if NO, the procedure goes to step 108.

In step 104, the control mode is switched to the second state, that is, the attitude control mode is set, and the process proceeds to step 105.

In step 105, it is determined whether or not the vehicle stop detection unit 3 derives a vehicle stop detection signal indicating that the vehicle is in a stopped state. If YES, then go to step 106, and if NO, go to step 108. move on.

In step 106, it is determined whether or not the switching signal generator 1 has again derived the mode switching signal. If YES, the process proceeds to step 108, and if NO, the process proceeds to step 107.

In step 107, it is judged whether or not the operation switch 2 has not led out an operation signal for one minute or more, and if YES, the process proceeds to step 108, and if NO, the process proceeds to step 105.

In step 108, the control mode is set to the first state, that is, the wiper control mode, and the process proceeds to step 101.

In short, the mode switching unit 4 sets the control mode to the second state, that is, the attitude control mode, when the vehicle is stopped and the switching signal generating unit 1 derives the mode switching signal. As a result, the mode switching unit 4 transmits the operation signal of the operation switch 2 to the second control circuit unit 6 including the posture control circuit.

In addition, the mode switching unit 4 is configured such that when the vehicle is in a traveling state, when the switching signal generating unit 1 does not derive the mode switching signal, or when the switching signal generating unit 1 is set to the attitude control mode once, the switching signal generating unit 1 switches to the mode. The control mode is set to the first state, that is, the wiper control mode when the switching signal is derived or when the operation switch 2 does not derive the operation signal for 1 minute or more after the attitude control mode is set. As a result, the mode switching unit 4 transmits the operation signal of the operation switch 2 to the first control circuit unit 5 including the wiper control circuit.

[Effect of the device]

 According to the present invention, one switch device can be used for controlling a plurality of types of equipment without using a voice recognition device or a display device due to the above configuration and operation. Further, according to this invention, when the predetermined time has passed from the mode switching or when the vehicle is in the running state, the original wiper control mode is automatically restored, so that a means for recognizing the very switching mode of the display device is required.
