Therefore, control parameters (or ideal circular locus data) for giving an operational feeling based on the input operation locus can be changed for each individual according to the size of the individual hand so as to reduce this deviation. Is desired.

However, for example, when the user individually sets the parameter values, it is troublesome for the user. In addition, even when individual parameters are created in advance and their own parameters are selected and set, it takes time and effort similarly.

(1st Embodiment)
The input device 100 according to the first embodiment is shown in FIGS. The input device 100 is a device for performing input operations such as setting of operating conditions for on-vehicle equipment of a vehicle. Examples of the in-vehicle device include an adaptive cruise control (ACC) device, an advanced driver assistance system (ADAS), an air conditioner, and an audio device. As shown in FIGS. 1 to 4, the input device 100 includes a display unit 110, an operation unit 120, an input operation support module 130, and the like.

The display unit 110 is a display device that displays, for example, the operating state of the vehicle-mounted device and operation items for input operation. As illustrated in FIG. 2, the display unit 110 illustrates an example in which a virtual image such as an operation item is displayed on a front window by a head-up display (HUD) device, for example. The display unit 110 may be a liquid crystal display unit provided in a combination meter, a center display unit for a car navigation device mounted on an instrument panel, or the like.

As display contents on the display unit 110, for example, a switch image 111a for speed setting in the ACC device, a pointer image 111b indicating the operation position of the operation knob 121, and a set speed image 111c set by the operator are displayed. It is supposed to be. The display content corresponds to, for example, an operation item, an operation state, and the like. The switch image 111a corresponds to, for example, a switch icon. The pointer image 111b corresponds to, for example, a pointer icon. The set speed image 111c corresponds to, for example, a set speed icon.

The switch image 111a is a circular switch image 111a, and is designed to image a circular dial-type switch that is rotated. The pointer image 111b has a design showing circular dots. The speed value is numerically displayed on the set speed image 111c.

The operation unit 120 enables an input operation on the circular switch image 111a displayed on the display unit 110. The operation unit 120 is provided at a position distant from the display unit 110, here, as shown in FIG. 3, at a spoke 51 (for example, a right spoke 51) that connects the ring and the boss of the steering wheel 50 of the vehicle. The input operation can be performed by the thumb F of the user holding the steering wheel 50 (for example, the thumb F of the right hand). The operation unit 120 includes an operation knob 121, a reaction force generation unit 122, a position detection sensor 123, a push operation detection sensor 124, a control unit 125, and the like.

The operation knob 121 is a part that slides on a virtual plane of the operation unit 120 by a user's finger operation. Since the operation unit 120 is provided on the spokes 51 of the steering 50, the virtual plane is a plane including the periphery of the ring of the steering 50 here. Since the operation knob 121 slides on a virtual plane, the operation unit 120 is a biaxial (for example, x, y axis) slide type remote operation device. In the present embodiment, for example, the x-axis is a left-right axis, and the y-axis is a vertical axis.

ポインタ By sliding the operation knob 121 in the two axial directions, the pointer image 111b is displayed on the display unit 110 so as to correspond to the slide position of the operation knob 121.

The reaction force generator 122 is a part that generates an operation reaction force on the operation knob 121. For example, when the pointer image 111b on the display unit 110 approaches the circular switch image 111a with the sliding movement of the operation knob 121, the reaction force generating unit 122 tries to move away from the circular switch image 111a. The operation knob 121 generates a pulling force that pulls the switch image 111a. The retraction force corresponds to, for example, an operation reaction force. The circular switch image 111a corresponds to, for example, a circular locus of the reaction force control map in FIG.

For example, as shown in FIG. 4, the position detection sensor 123 generates a position signal indicating the current position of the operation knob 121 in an operation area where the operation knob 121 can be operated, and Output part. Specifically, the position detection sensor 123 outputs a position signal of the operation knob 121 based on the x and y coordinates to the control unit 125. Therefore, the position detection of the present embodiment is an absolute coordinate detection using the x and y coordinates.

The push operation detection sensor 124 is a part that generates a push signal when the user pushes the operation knob 121 and outputs the signal to the control unit 125. In the operation unit 120, the push operation detection sensor 124 may be omitted.

The control unit 125 outputs the position signal from the position detection sensor 123 and the push signal from the push operation detection sensor 124 to the input operation support module 130 as input data. The control unit 125 is a part that controls the state of the operation reaction force generation in the reaction force generation unit 122 based on the position signal from the position detection sensor 123.

The control unit 125 stores, for example, a reaction force control map shown in FIG. 4 in advance, and uses this reaction force control map when generating an operation reaction force on the operation knob 121. . Here, when the operation knob 121 is operated to draw a circle along the circular switch image 111a, the retraction force is applied from the position of the operation knob 121 toward the circular locus so that a smooth operation can be performed. Is to be granted.

In the reaction force control map, for example, as shown in a range from (0, 0) to (255, 255) in the xy coordinates, an operation area in which the operation knob 121 can be operated (operated) is set. It is a defined map. In addition, in the reaction force control map, a circular locus or a circular line corresponding to the circular switch image 221 is defined at the center of the operation area as an initial position. A retraction force control region is defined as a region to which the retraction force is applied when the operation knob 121 is operated. In FIG. 4, the retraction force control area is a ring-shaped area having a predetermined width and including a circular locus. The circular locus is defined so as to be located at the center position of a predetermined width with respect to the pull-in force control area. In addition, as shown in FIG. 4, the circular locus corresponds to, for example, a circular locus drawn in as tactile feedback or a circular locus assumed by the system.

The input operation support module 130 is a part that performs input operation support for the in-vehicle device based on input data by an input operation on the operation unit 120 and updates an operation feeling parameter related to a user's operation feeling on the operation unit 120. I have. The input data corresponds to, for example, a position signal or a pressing signal. The operation feeling parameter corresponds to, for example, the above-described reaction force control map in the present embodiment. The input operation support module 130 includes an input operation receiving unit 131, a control unit 132, an operation feeling parameter updating unit 133, an operation target GUI (Graphical User Interface) 134, an operation feeling parameter transmission unit 135, and the like. The input operation support module 130 forms a control unit of the present disclosure together with the control unit 125 in the operation unit 120 described above.

The input operation receiving unit 131 is a unit that receives input data associated with an input operation on the operation unit 120. The input operation receiving unit 131 outputs the received input data to the control unit 132. The input data corresponds to, for example, a position signal and a pressing signal.

The control unit 132 is a unit that outputs the input data of the operation unit 120 output from the input operation receiving unit 131 to the operation feeling parameter updating unit 133 and the operation target GUI 134.

The operation feeling parameter update unit 133 extracts the actual input operation trajectory of the user based on the input data output from the control unit 132 as shown in FIGS. This is a part that determines the characteristics of the trajectory and updates the reaction force control map in the operation unit 120 to a suitable reaction force control map. The operation sensation parameter updating unit 133 includes an operation trajectory extraction unit 133a, an operation trajectory storage unit 133b, an operation trajectory feature determination unit 133c, an operation sensation parameter calculation unit 133d, and the like.

The operation trajectory extraction unit 133a is a part that extracts an input operation trajectory in the operation range of the reaction force control map from the position signal obtained by the position detection sensor 123. Hereinafter, the operation trajectory extraction unit 133a will be referred to as an extraction unit 133a.

The operation trajectory storage unit 133b stores the input operation trajectory extracted by the extraction unit 133a. Hereinafter, the operation trajectory storage unit 133b will be referred to as a storage unit 133b.

The operation trajectory feature determination unit 133c is a part that compares the circular trajectory in the operation range with the input operation trajectory stored in the storage unit 133b to determine the feature of the input operation trajectory. Hereinafter, the operation trajectory feature determination unit 133c will be referred to as a determination unit 133c.

The operation feeling parameter calculation unit 133d calculates a suitable reaction force control map suitable for the user based on the characteristics of the input operation trajectory determined by the determination unit 133c with respect to the reaction force control map in the operation unit 120. It has become. Hereinafter, the operation feeling parameter calculation unit 133d is referred to as a calculation unit 133d. The calculation unit 133d outputs the calculated suitable reaction force control map to the operation target GUI 134 and the operation feeling parameter transmission unit 135.

Each

part

133a, 133b, 133c, 133d in the operation feeling parameter updating unit 133 may be formed as an independent circuit unit, or may be virtually formed by software on a microcomputer. Is also good. The circuit section corresponds to hardware.

The operation target GUI 134 is a part that forms an interface unit with the in-vehicle device, and is based on input data output from the control unit 132 and suitable parameter values (for example, a reaction force control map) output from the calculation unit 133d. Then, an operation instruction is issued to the in-vehicle device, and a display instruction is issued to the display unit 110 so that the display content is based on the operation instruction. Further, the operation target GUI 134 outputs the display unit information instructed to the display unit 110 to the determination unit 133c. The display instruction corresponds to, for example, a video output.

The operation feeling parameter transmission unit 135 is a unit that transmits the suitable reaction force control map output from the calculation unit 133d to the control unit 125 of the operation unit 120.

The configuration of the input device 100 according to the present embodiment is as described above. Hereinafter, the operation and the effect will be described with reference to FIGS.

For example, when executing the ACC (Adaptive Cruise Control) control, the user mainly operates the operation knob 121 with the thumb F while watching the circular switch image 111a on the display unit 110 to set the traveling speed. Operate. First, the user operates the operation knob 121 left / right, up / down, or obliquely so that the pointer image 111b overlaps (ie, approaches) an arbitrary position in the circumferential direction of the circular switch image 111a. Is moved to the circular switch image 111a.

Furthermore, when the user operates the operation knob 121 so as to draw a circle, the pointer image 111b is moved along the circumferential direction of the circular switch image 111a. The set value of the traveling speed in the ACC control is increased or decreased according to the rotation direction of the pointer image 111b at this time. The set value of the traveling speed increases when the pointer image 111b is rotated clockwise or clockwise), and decreases when the pointer image 111b is rotated counterclockwise or counterclockwise.

The set value of the traveling speed that is increased or decreased is displayed in real time as the set speed image 111c. When the set value of the traveling speed reaches a desired value, the user presses the operation knob 121 to set the set value. Is determined. The control unit 125 outputs the above set value (for example, input data) to the input operation support module 130 (for example, instructs ACC control), so that the ACC device starts control of constant speed traveling.

制御 As described above, when the operation knob 121 is operated, the control unit 125 activates the reaction force generation unit 122 to apply a pull-in force to the operation knob 121. The control unit 125 controls the reaction force generation unit 122 such that, for example, the longer the distance between the circular locus and the operation knob 121 in the reaction force control map, the larger the retraction force is set. The circular locus corresponds to the circular switch image 111a. The operation knob 121 corresponds to the pointer image 111b. Thereby, the operation knob 121 is drawn into the circular locus, and the user can operate the operation knob 121 so as to draw a smooth circle on the circular switch image 111a. Due to the retraction force, the input operation trajectory is concentrated on the circular trajectory in the reaction force control map as shown in FIG.

Here, for example, if the user is a smaller person than a person with a standard physique, his hand is small, and his thumb F is short, as shown in FIG. May be shifted to the right with respect to the circular locus. Alternatively, as shown in FIG. 8, when drawing an input operation trajectory deviated to a specific range, the input operation trajectory may be similarly shifted to the right with respect to the circular trajectory. Further, even if the person has a standard physique, he / she wants to operate with a short stroke (that is, a small circular locus). As shown in FIG. 10, the input operation locus may be shifted inside the circular locus. There is.

As described above, when the actual input operation trajectory deviates from the circular trajectory, the retraction force is set according to the distance between the circular trajectory and the operation knob 121 as described above. The operation is performed while feeling a large retraction force, and the operation of drawing a smooth circle cannot be performed. Along with this, the user feels that the operation is difficult due to erroneous operation or finger fatigue.

Therefore, in the present embodiment, the control unit 125 and the input operation support module 130 store the history of the actual input operation trajectory of the thumb F to the operation knob 121 and store the history of the actual input operation trajectory in the reaction force control map. The center position and the radius of the circular locus are automatically updated so as to match. FIG. 12 is a flowchart showing a procedure for automatically updating the reaction force control map.

First, in step S100, the control unit 125 and the input operation support module 130 extract the history of the input operation trajectory by the circle operation in the reaction force control map. Then, in step S110, it is determined whether or not the input operation trajectory of the designated number or more (for example, two or more) has been extracted. If a negative determination is made in step S110, the process returns to step S100.

If the determination is affirmative in step S110, the control unit 125 and the input operation support module 130 calculate the center position and radius of the circle of the input operation trajectory in the reaction force control map by, for example, the least square method in step S120.

Then, in step S130, the control unit 125 and the input operation support module 130 set the center position and radius of the circular locus in the reaction force control map to the center position and radius of the circle of the input operation locus calculated above. Automatically update to.

制御 By this control, for example, in the case described with reference to FIG. 6, as shown in FIG. 7, the circular locus is automatically updated so as to match the input operation locus (that is, to overlap). Specifically, the center position of the circular locus is moved to the right and automatically updated so as to increase the radius. FIG. 7 shows the result of automatic updating according to the operation history. In addition, in the case described with reference to FIG. 8, as shown in FIG. 9, the circle locus is automatically updated so as to match the input operation locus (that is, so as to overlap). Specifically, the center position of the circular locus is moved to the right and automatically updated so as to increase the radius. FIG. 9 shows a result of automatic updating according to an operation history biased to a specific range. Further, in the case described with reference to FIG. 10, as shown in FIG. 11, automatic updating is performed so that the circular locus matches the input operation locus (ie, overlaps). Specifically, while the center position of the circular trajectory remains the same, it is automatically updated so that the radius becomes smaller. FIG. 11 shows the result of reducing the radius of the circular locus.

As described above, according to the present embodiment, the control unit 125 and the input operation support module 130 store the input operation trajectory of the user on the operation knob 121, and the center position of the circular trajectory matches the input operation trajectory. , And the radius is updated. Accordingly, an operation reaction force is applied at a position where the user can easily operate, and a plurality of circular trajectories are prepared and stored in advance in order to update the circular trajectory for the user to operate. It is not necessary to perform an operation for updating the circular trajectory, and it is possible to tune the operational feeling without trouble for the user.

(2nd Embodiment)
A second embodiment is shown in FIGS. In the second embodiment, when a user makes an erroneous operation on the operation knob 121, the reaction force control map is automatically updated.

For example, as shown in FIG. 13, when the circular locus in the reaction force control map is set to be relatively small, the user can perform an input operation with a short stroke, but on the other hand, slides the operation knob 121 slightly. Just by doing, the operation target in the ACC, for example, the set value of the traveling speed changes. Therefore, when the slide amount is relatively large, a situation occurs in which the set value greatly changes against the user's intention.

In such a situation where the set value overshoots, the user tends to suddenly change the operation direction of the operation knob 121 to the opposite side. Therefore, in the present embodiment, as the erroneous operation,
When the speed down operation is performed immediately after the speed up operation (for example, the operation shown in FIG. 14), or
The case where the speed-up operation is performed immediately after the speed-down operation (for example, the reverse operation shown in FIG. 14) is defined. The erroneous operation is an operation in which the operation direction of the operation knob 121 is suddenly changed to the opposite side.

Then, the control unit 125 and the input operation support module 130 automatically update the reaction force control map at the time of erroneous operation based on the flowchart shown in FIG. First, in step S200, the control unit 125 and the input operation support module 130 extract the history of the input operation trajectory by the circular operation in the reaction force control map.

Next, in step S210, the control unit 125 and the input operation support module 130 determine whether or not the operation knob 121 has been rotated in the opposite direction within a fixed time after being rotated in the fixed direction. If an affirmative determination is made in step S210, the above-described definition of the erroneous operation is met, and it is determined that there is an erroneous operation, and the process proceeds to step S220. If a negative determination is made in step S210, the process returns to step S200.

The determination in step S210 may be such that an erroneous operation is performed when a predetermined number of erroneous operations occur for a single erroneous operation as described above.

Then, in step S220, the control unit 125 and the input operation support module 130 increase the radius of the circular locus in the reaction force control map by a certain amount as shown in FIG.

Accordingly, if there is an erroneous operation on the operation knob 121, the radius of the circular locus is updated to be larger, so that the operability can be improved as compared with the case where the operation range is small, and subsequent erroneous operations can be performed. Is suppressed.

(Other embodiments)
In the first embodiment, the center position and radius of the circular trajectory are automatically updated with respect to the actual input operation trajectory. In the second embodiment, the radius of the circular trajectory is increased if there is an erroneous operation. Although the automatic update is performed in the first embodiment, a combination of the two embodiments may be used.

Further, in each of the above embodiments, the operation target device is the ACC device, and the running speed and the like in the ACC control are described. However, the present invention is not limited to this. The present invention may be applied to adjustment of a volume, adjustment of a set temperature in an air conditioner, and the like.

The flowchart described herein or the processing of the flowchart is composed of a plurality of steps (or referred to as sections), and each step is expressed as, for example, S100. Further, each step can be divided into multiple sub-steps, while multiple steps can be combined into one step.
