As described above, by controlling the driving of the plurality of function adjustment units provided in the on-vehicle electric device by operating the rotation operation unit provided on the on-vehicle electric device control device, one rotation operation unit can control one drive. Various functions of the in-vehicle electric device can be adjusted, so that the configuration of the in-vehicle electric device control device can be simplified and its size can be reduced as compared with a case where a different operation member is operated for each function. Can be. In addition, since all functions of the in-vehicle electric device can be adjusted while the rotation operation unit is rotated by 360 degrees, the function adjustment of the in-vehicle electric device is facilitated and the operability is excellent. Furthermore, since the function of one in-vehicle electric device is adjusted by one rotation operation unit, the functions to be adjusted are compared with the case of adjusting the functions of a plurality of in-vehicle electric devices by one operation unit. The total number can be reduced, the difference in the force sense given to the rotary operation unit according to each function can be increased, and the operation of the rotary operation unit by blind touch can be facilitated.

Further, according to the present invention, in the on-vehicle electric device control device having the above-described configuration, the control unit may be configured to control the rotation angle of the rotation operation unit to one of the plurality of function adjustment units to control the drive of the function adjustment unit. When a boundary between the rotation angle range for outputting the rotation angle range and the rotation angle range for outputting the drive control signal of the function adjustment unit to the other function adjustment units is reached, the drive control of the external force generation unit specific to the boundary portion is performed. A signal is output to the external force generating unit.
[0014]
In this way, the boundary is set in the rotation direction of the rotary operation unit, and when the rotation angle of the rotary operation unit reaches the boundary, the drive control signal of the external force generation unit specific to the boundary is transmitted to the external force generation unit. When output, the operator can know by blind touch that the function of the in-vehicle electric device to be adjusted has been switched by sensing a force sense corresponding to the drive control signal of the external force generating unit peculiar to this boundary portion.

It was configured to do.
[0016]
As described above, when the drive control signal of the external force generator that is different for each boundary portion is output to the external force generator, the operator should adjust the force sense by feeling the difference in the force sense according to the difference of each drive control signal. Since it is possible to know which function of the on-vehicle electric device has been switched by a blind touch, the function adjustment of the on-vehicle electric device can be made easier.
[0017]
Further, in the present invention, in the on-vehicle electric device control device having the above-described configuration, a switch operated by an operator is attached to the rotary operation unit.
[0018]
In this way, if a switch is attached to the rotation operation unit, other functions can be added to the on-vehicle electric device control device by using a switch signal output by operating the switch. And / or multiple functions can be achieved.
[0019]
Further, according to the present invention, in the in-vehicle electric device control device having the above-described configuration, the rotary operation portion is configured to be rotatable and pressable, and the movable portion of the switch in the pressing direction of the rotary operation portion is provided with a movable portion of the switch. It was configured to be connected.

In this manner, when the movable portion of the switch is exposed and arranged in a part of the rotary operating portion, the rotating operation of the rotary operating portion and the pressing operation of the switch can be performed as separate operations. The inconvenience of accidentally pressing the switch during operation is unlikely to occur, and the operability and reliability of the on-vehicle electric device control device can be improved.
[0023]
Further, according to the present invention, in the in-vehicle electric device control device having the above-described configuration, the switch functions as a determination unit of a function adjustment operation of the in-vehicle electric device performed by operating the rotation operation unit. When the switch is operated in a state where the rotation operation unit is rotated from the reference position, the drive control signals corresponding to the rotation angle of the rotation operation unit are output to one of the function adjustment units and the external force generation. And output it to the unit.
[0024]
In this manner, if the rotary operation unit is provided with a switch as a means for determining a function selection operation, simply rotating the rotary operation unit does not adjust the functions of the vehicle-mounted electric device. The functions of the onboard electric device are adjusted only by operating the switch while rotating to the position of, so that unnecessary force sensation can be prevented, and the function adjustment of the desired onboard electric device can be performed quickly. And can be performed accurately.
[0025]
Further, according to the present invention, in the on-vehicle electric device control device having the above-described configuration, an operation position of the rotation operation unit and the rotation position are provided on a surface of the rotation operation unit and a front panel of the on-vehicle electric device provided with the rotation operation unit. A mark for displaying the function of the on-vehicle electric device adjusted when the operation unit is operated to a predetermined operation position is formed.
[0026]
As described above, when the required mark is displayed on the surface of the rotary operation unit and the front panel of the on-vehicle electric device, the operator visually checks the mark as well as the force sense applied to the rotary operation unit by the external force generation unit. In this way, the details of the function adjustment of the on-vehicle electric device can be confirmed, so that the contents of the function adjustment can be easily confirmed, and the use of the on-vehicle electric device can be made more convenient.
