  However, in the above-described conventional vehicle-mounted device operating device, when operating the vehicle-mounted device while the vehicle is running, the driver can reduce the amount of movement of the line of sight and improve the operability of the vehicle-mounted device. Even when the driver is gazing at the front of the run, such as during operation, there is a problem that it is necessary to operate the in-vehicle device while viewing the display on the front window.

  The present invention solves such a conventional problem, and an object of the present invention is to provide an in-vehicle device operation device capable of further improving the operability of the in-vehicle device even during a rotation operation of the handle.

  In order to achieve the above object, the vehicle-mounted device operating device of the present invention has the following configuration.

  The invention according to claim 1 of the present invention is configured such that the control unit performs a predetermined correction on the input signal of the input unit by the steering angle signal of the steering angle detection unit and sets the operation of the in-vehicle device. Since the in-vehicle device can be operated with the operation direction of the input unit kept constant even during the rotation operation of the handle, etc., there is an effect that an in-vehicle device operation device that can further improve the operability of the in-vehicle device can be obtained. Have.

  According to a second aspect of the present invention, in the first aspect of the invention, the predetermined correction performed by the control unit is performed based on a position where the operation angle of the handle is zero (hereinafter referred to as a neutral point). The operation direction of the input unit can be made constant regardless of the operation angle of the handle.

  As described above, according to the present invention, in the in-vehicle device operating device for performing the operation setting of the in-vehicle device, there is an advantageous effect that an in-vehicle device operating device that can further improve the operability of the in-vehicle device can be obtained. can get.

  Embodiments of the present invention will be described below with reference to FIGS.

(Embodiment)
FIG. 1 is an explanatory diagram of an in-vehicle device operating device according to an embodiment of the present invention, FIG. 2 is a block diagram thereof, FIG. 3 is a plan view of the input unit, in which 1 is a handle and 2 is an input unit Thus, the input unit 2 is disposed at a position where the driver on the front surface of the spoke portion of the handle 1 can operate. Reference numeral 5 denotes a rudder angle detector, and the rudder angle detector 5 is formed so as to detect the operation angle of the handle 1.

  Note that the input unit 2 can be operated in multiple directions. For example, a planar operation unit is operated with a finger, and the finger position is detected by an electrostatic method, or the rotation position of a ball is detected by a roller. Multi-directional operation means such as a trackball input device and a touch panel device that detects a finger pressing operation position by a resistance method can be used.

  The steering angle detection unit 5 capable of detecting the operation angle of the handle 1 is provided with a slit in a disk engaged with the steering interlocked with the handle 1 and optically detects the number of slits accompanying the rotation of the disk. Further, a magnetic system that magnetically detects the rotation of the sub-rotator accompanying the rotation of the rotating body by engaging the gear of the sub-rotating body with the gear of the rotating body engaged with the steering can be used.

  Then, the input signal S1 of the input unit 2 and the steering angle signal S2 of the steering angle detection unit 5 are input to the control unit 7, and the control unit 7 performs a predetermined correction on the input signal S1 based on the steering angle signal S2. The in-vehicle device operating device 10 is configured to output S3 and select / determine the in-vehicle device 9 in the menu displayed on the display unit 8 by the control signal S3.

  In the above configuration, in this embodiment, as shown in FIGS. 1 and 3, the rotational positions of the handle 1 and the input unit 2 are A to H divided into 360 degrees by eight, and the A to H data and the handle A neutral point position where the operation angle is zero is stored in the control unit 7. Further, the menu screen of the display unit 8 shown in FIG. 4 will be described on the assumption that the radio 9B is selected in the initial state and the movement is selected from this state to the audio 9C.

  First, when the steering wheel 1 is not operated to rotate, that is, when the driver selects to move from the radio 9B to the audio 9C in a straight-on state during straight running, when the driver operates the operation unit 2A of the input unit 2 once in the A direction, When the cursor moves to the position of the audio 9C and the driver presses the operation unit 2A at this position, a switch (not shown) disposed below the operation unit 2A is turned on, and the audio 9C is selected and confirmed.

  It should be noted that in the directly facing state during the straight running, the control unit 7 detects that the rudder angle signal S2 of the rudder angle detection unit 5 is 0 degree, and based on the detection result, the input signal S1 of the input unit 2 The control signal S3 is output without correction, and the cursor is moved to the position of the audio 9C in the A direction by the control signal S3.

  Next, when the steering wheel 1 is rotated 45 degrees to the left as shown in FIG. 5 (the steering angle signal S2 is 45 degrees to the left) and the movement is selected from the radio 9B to the audio 9C in the rotating state during the rotational travel. Conventionally, the driver needs to recognize the rotation angle of the handle 1 and operate the operation unit 2A in the same direction A as in the directly-facing state. However, in the present invention, the operation is performed regardless of the rotation angle of the handle 1. The part 2A can be operated in the same direction from the neutral point, that is, in the B direction.

  This is because the control unit 7 detects that the steering angle signal S2 of the steering angle detection unit 5 is 45 degrees to the left, and on the basis of the detection result, the input of the input unit 2 is set to 45 degrees to the right. A control signal S3 obtained by correcting the signal S1 is output, and the cursor is moved in the position of the audio 9C, that is, in the B direction by the control signal S3. When the driver presses the operation unit 2A at this moving position, the switch is turned on, and the audio 9C is selected and confirmed.

  When the resolution in 8 directions A to H is required as in this example, the control unit 7 has the input direction of the input unit 2 as the reference direction, and in this example, the range of ± 20 degrees with respect to the B direction is the B direction. And an allowable range is provided so as to output the control signal S3.

  As described above, according to the present embodiment, the control unit 7 performs a predetermined correction on the input signal S1 by the steering angle signal S2, thereby keeping the operation direction of the input unit 2 constant even during the rotation operation of the handle 1. Since the in-vehicle device 9 can be operated as described above, an in-vehicle device operation device that can further improve the operability of the in-vehicle device can be obtained.

  In addition, since the predetermined correction performed by the control unit 7 is performed based on the position of the neutral point of the handle 1, the input unit 2 can be operated in a constant direction regardless of the operation angle of the handle 1.

  The vehicle-mounted device operating device according to the present invention has an effect that the driver does not move the line of sight even during the rotation operation of the handle, and can be further improved in the operability of the vehicle-mounted device, and is mounted on the vehicle. This is useful for an in-vehicle device operating device for setting the operation of the in-vehicle device.
