JP 2009-96210 A

However, the necessity of gripping the steering operation unit during automatic driving is reduced. Nevertheless, there is a problem that the driver feels inconvenient that only the four corners of the touch panel display can be operated.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of performing an operation suitable for automatic driving in a touch device of a steering operation unit.

  In order to achieve the above object, the information input system of the present invention is configured such that an operation receiving unit that receives an operation on a touch device provided in a steering operation unit, and a moving body that is steered by the steering operation unit is in an automatic operation. A state determination unit that determines whether or not the vehicle is in manual operation, and an operation region setting unit that increases an operation region for receiving an operation on the touch device when in automatic operation and when in manual operation. Prepare.

  In order to achieve the above object, an information input program according to the present invention includes a computer, an operation receiving unit that receives an operation on a touch device provided in a steering operation unit, and a moving body that is steered by the steering operation unit is in automatic driving. As a state determination unit that determines whether there is a manual operation, an operation region setting unit that increases the operation region that accepts an operation on the touch device when in automatic operation than when in manual operation Make it work.

  In the above-described configuration, during the automatic operation in which the necessity of gripping the steering operation unit is reduced, the operation area can be made larger than during the manual operation, and the degree of freedom of operations that can be accepted can be increased.

It is a block diagram of an information input system. 2A to 2C are front views of the steering operation unit. It is a flowchart of an information input process.

Here, embodiments of the present invention will be described in the following order.

(2) Information input processing:
(3) Other embodiments:

(1) Configuration of information input system:
FIG. 1 is a block diagram showing a configuration of an information input system 10 according to an embodiment of the present invention. The information input system 10 is a vehicle-mounted device such as a car navigation device mounted on a vehicle. The information input system 10 includes a control unit 20 and a recording medium 30. The control unit 20 includes a CPU, a RAM, a ROM, and the like, and executes an information input program 21 stored in the recording medium 30 or the ROM.

  The recording medium 30 records map information 30a and operation plan information 30b. The map information 30a includes node data, link data, and facility data. The node data mainly indicates information about the intersection. Specifically, the node data indicates the coordinates of the node corresponding to the intersection and the shape of the intersection. The link data indicates various types of information such as a section length, a speed limit, the number of lanes, and the width of the link corresponding to the road section. A road section is a unit of road divided by intersections continuous in the length direction, and nodes exist at both ends of the link. A node to which three or more links are connected corresponds to an intersection. The section length is the length of the road section, and means the travel distance when traveling on the road section.

  The link data includes shape interpolation point data. The shape interpolation point data is data indicating the coordinates of the shape interpolation point set at the center in the width direction of the road section. The control unit 20 acquires the coordinates of the node and the coordinates of the shape interpolation point, and acquires a polygonal line connecting these coordinates or an approximate curve of these coordinates as the shape of the road section.

  The driving plan information 30b is data defining a control target value for each target position that is the current location of the target vehicle. In the present embodiment, it is assumed that the target vehicle speed, the target acceleration / deceleration, and the target steering angle are recorded in the driving plan information 30b as the control target values. The control target value may be recorded for each time during automatic operation. The control unit 20 controls each part of the vehicle so that the current position reaches each target position, and controls each part of the vehicle so that each control target value is realized at a timing when the current position reaches each target position. The driving plan information 30b may be modified as appropriate according to the traveling state of the vehicle. The technique for automatically driving the vehicle is not particularly limited, and a known automatic driving technique can be applied, and the control target value is not limited to that described above.

  In the present embodiment, the planned travel route is searched as the optimum route to the destination, and the operation plan information 30b for traveling on the planned travel route is created. That is, the target position indicated by the operation plan information 30b is, for example, a plurality of positions set at regular intervals on the planned travel route, and travels on the planned travel route by following the target position. can do. However, the target position indicated by the operation plan information 30b does not necessarily have to be set for the entire planned travel route, and the target position is not set in the manual operation section where the automatic operation is not performed on the planned travel route.

  Here, the manual driving section is a section where automatic driving becomes difficult for some reason, for example, a section where the road shape is complicated, a section where the accuracy of identifying the current location decreases, or a section where there are many obstacles such as pedestrians Alternatively, it may be a section where the behavior of the vehicle becomes unstable. Furthermore, the manual operation section may be set according to dynamic factors such as weather. In the manual operation section, manual operation by the driver is performed.

  The target vehicle speed is set so that the vehicle can run at a constant speed at the limit vehicle speed indicated by the link data of the map information 30a. Further, the target vehicle speed is set so as to gradually decelerate toward the planned stop point or to gradually accelerate from the planned stop point to the limit vehicle speed. Further, the target vehicle speed is set based on the curve shape of the road section specified based on the shape interpolation point data.

  The vehicle includes a GPS receiver 41, a vehicle speed sensor 42, a gyro sensor 43, a vehicle control ECU (Electronic Control Unit) 44, a steering unit 44a, an acceleration / deceleration unit 44b, a steering operation unit 45, a touch panel display 46, and a touch sensor 47. ing. The GPS receiver 41 receives radio waves from GPS satellites and outputs a signal for calculating the position of the vehicle via an interface (not shown). The vehicle speed sensor 42 outputs a signal corresponding to the rotational speed of the wheels provided in the vehicle. The control unit 20 acquires the vehicle speed based on a signal from the vehicle speed sensor 42. The gyro sensor 43 detects angular acceleration about turning in the horizontal plane of the vehicle, and outputs a signal corresponding to the direction of the vehicle. The control unit 20 acquires the traveling direction of the vehicle based on the signal from the gyro sensor 43. The control unit 20 acquires the current location of the vehicle based on output signals from the GPS receiving unit 41, the vehicle speed sensor 42, and the gyro sensor 43.

  The vehicle control ECU 44 is a computer for controlling each controlled device of the vehicle. The controlled device includes at least a steering unit 44a and an acceleration / deceleration unit 44b. The steering unit 44a is a mechanism for controlling the direction of the wheels (steering wheels), and includes a steering gear box that operates based on the control of the vehicle control ECU 44. During the automatic operation, the steering unit 44a operates the steering gear box, so that the steering is automatically performed. The steering gear box and the steering operation unit 45 are mechanically coupled, and the steering operation unit 45 rotates so as to follow the operation of the steering gear box during automatic driving. The steering operation unit 45 is a so-called steering wheel. During manual operation, the driver can manually perform steering by gripping and rotating the steering operation unit 45 to operate the steering gear box.

  The acceleration / deceleration unit 44b includes an acceleration unit and a deceleration unit that operate based on the control of the vehicle control ECU 44. The acceleration unit is a mechanism for increasing the output of a drive source such as an engine or a motor. The speed reduction unit is a mechanism for controlling a friction brake, an engine brake, and a regenerative brake. The vehicle includes an accelerator pedal and a brake pedal (not shown), and the driver can control the acceleration / deceleration unit 44b by operating the accelerator pedal and the brake pedal.

  The vehicle control ECU 44 acquires signals indicating the control states of the steering unit 44a and the acceleration / deceleration unit 44b, and performs feedback control of the steering unit 44a and the acceleration / deceleration unit 44b based on the signals, thereby automatically according to the driving plan information 30b. Driving can be realized.

  FIG. 2A shows the steering operation unit 45 when traveling straight and during manual operation. The steering operation unit 45 includes a touch panel display 46 and a touch sensor 47. The steering operation unit 45 has an annular gripping part H that can be gripped by the driver, and is provided with a rectangular touch panel display 46 so as to be inscribed in the gripping part H. The touch panel display 46 serves as both a touch device that detects the contact position of the driver's finger and a display that displays an image under the control of the control unit 20. That is, in this embodiment, the touch device is configured by the touch panel display 46. The touch sensor 47 is also a touch device that detects the contact position of the driver's hand, and detects the grip position of the driver's hand in the entire grip portion H. The upper side and the lower side of the touch panel display 46 are horizontal during straight traveling.

  The information input program 21 includes an automatic operation module 21a, an operation reception module 21b, a state determination module 21c, an operation area setting module 21d, and a display control module 21e. The operation reception module 21b, the state determination module 21c, the operation region setting module 21d, and the display control module 21e are program modules that cause the control unit 20 as a computer to function as an operation reception unit, a state determination unit, and an operation region setting unit, respectively. .

  The control unit 20 creates the above-described operation plan information 30b by the function of the automatic operation module 21a, and controls the vehicle control ECU 44 according to the operation plan information 30b. That is, by the function of the automatic driving module 21a, the control unit 20 creates driving plan information 30b that defines a target position and a control target value for automatically controlling the vehicle for each target position by a known automatic driving technique. To do. And the control part 20 implement | achieves the automatic driving | operation of a vehicle by outputting the control target value prescribed | regulated to the driving plan information 30b to vehicle control ECU44 sequentially. Further, when creating the operation plan information 30b, the control unit 20 searches for an optimal planned travel route to the destination in advance by a known method such as the Dijkstra method, and sets a target position on the planned travel route. Thus, the operation plan information 30b for traveling on the planned travel route is created.

  With the function of the automatic driving module 21a, the control unit 20 starts automatic driving when the current location of the vehicle passes a start point (first target position) defined in advance in the driving plan information 30b. Similarly, the control part 20 complete | finishes an automatic driving | operation, when the end point (last target position) prescribed | regulated to the driving | operation plan information 30b is passed, and transfers to a manual driving | operation. During automatic driving, the steering of the steering unit 44a and the acceleration / deceleration of the acceleration / deceleration unit 44b are automatically controlled. The last target position is the destination of the planned travel route or the start point of the manual operation section.

  The control unit 20 receives an operation on the touch device (touch panel display 46) provided in the steering operation unit 45 by the function of the operation reception module 21b. Specifically, the control unit 20 acquires the movement vector of the finger contact position on the touch panel display 46 by the function of the operation reception module 21b, and converts the direction of the movement vector into the direction of the interior space coordinate system. The control unit 20 acquires from the vehicle control ECU 44 the rotation angle θ from when the steering operation unit 45 goes straight (clockwise on the paper is positive), and corrects the direction of the movement vector by −θ degrees. Thus, the direction in which the driver moves the finger can be acquired as the direction of the movement vector. The in-vehicle space coordinate system is a coordinate system that is independent of the rotation angle θ of the steering operation unit 45, and is a coordinate system that indicates a position in a space in the vehicle.

  With the function of the operation reception module 21b, the control unit 20 receives an operation associated with the direction of the movement vector in the vehicle interior space coordinate system. For example, when a movement vector in which the contact position moves upward in the operation region OR of FIG. 2A is acquired, the control unit 20 performs an operation for increasing the volume of a sound output from a speaker (not shown), a music playback unit ( (Not shown) may accept an operation of feeding music being played. Since the direction of the movement vector is rotationally corrected based on the rotation angle θ of the steering operation unit 45, even if the steering operation unit 45 is rotated by the rotation angle θ from the straight traveling position as shown in FIGS. 2B and 2C, the driver Can accept an operation corresponding to the direction in which the finger is moved.

  By the function of the state determination module 21c, the control unit 20 determines whether the vehicle as a moving body that is steered by the steering operation unit 45 is in automatic driving or manual driving. With the function of the state determination module 21c, the control unit 20 determines whether or not automatic driving is being performed with the function of the automatic driving module 21a. That is, the control unit 20 determines whether or not the steering unit 44a and the acceleration / deceleration unit 44b are automatically controlled.

  With the function of the operation area setting module 21d, the control unit 20 enlarges the operation area for accepting an operation on the touch device (touch panel display 46) when the automatic operation is being performed than when the operation is being performed manually. 2A shows the steering operation unit 45 during manual operation, and FIG. 2B shows the steering operation unit 45 during automatic operation. 2A and 2B, the operation areas OL, OR, and OA are indicated by broken line frames. The operation area OA during automatic operation shown in FIG. 2B is larger than the operation areas OL, OR during manual operation shown in FIG. 2A. It should be noted that the control unit 20 does not accept any operation even if the movement vector of the contact position in an area other than the operation areas OL, OR, OA on the touch panel display 46 is acquired by the function of the operation accepting module 21b.

  With the function of the operation area setting module 21d, the control unit 20 rotationally corrects the directions of the operation areas OL and OR on the touch panel display 46 based on the rotation angle θ. That is, the control unit 20 corrects the directions of the operation areas OL and OR so that the direction of the operation areas OL and OR in the interior space coordinate system is independent of the rotation angle θ of the steering operation unit 45. Therefore, even if the steering operation unit 45 is rotated by the rotation angle θ as shown in FIG. 2C, the operation areas OL and OR are not rotated from the direction of FIG. 2A.

  With the function of the operation region setting module 21d, the control unit 20 detects the gripping position of the steering operation unit 45 by the driver when manual driving is in progress, and causes the operation regions OL and OA to follow the gripping position. During manual operation, the control unit 20 uses the function of the operation area setting module 21d to cause the control unit 20 to grasp the grip position TL held by the driver in the grip part H based on the output signal of the touch sensor 47 provided in the grip part H. , TR are detected. Basically, since the grip portion H is gripped with both hands, the left and right grip positions TL and TR are detected.

  During manual operation, the control unit 20 sets the positions of the operation areas OL and OR on the touch panel display 46 so that the operation areas OL and OR are closest to the gripping positions TL and TR, respectively. For example, during manual operation, the control unit 20 has the entire operation areas OL and OR within the touch panel display 46, and the distance between the center of gravity of the gripping positions TL and TR and the center of gravity of the operation areas OL and OR is the shortest. The positions of the operation areas OL and OR are set so that It is assumed that the operation areas OL and OR are maintained in a predetermined shape.

  With the function of the operation area setting module 21d, the control unit 20 sets the entire touch device (touch panel display 46) as the operation area OA when automatic operation is in progress. That is, as shown in FIG. 2B, the control unit 20 performs settings on the entire touch panel display 46 on which a map is displayed by the function of the operation area setting module 21 d. For example, when the flick operation is performed at any position in the operation area OA, the control unit 20 may accept an operation of scrolling the map in the direction of the flick operation by the function of the operation area setting module 21d. Further, the control unit 20 may accept an operation for changing the scale of the map when a pinch operation (pinch-in operation / pinch-out operation) is performed at any position in the operation area OA.

  By the function of the display control module 21e, the control unit 20 enlarges the display area for displaying information on the touch device (touch panel display 46) when the automatic operation is being performed than when the manual operation is being performed. Specifically, as shown in FIGS. 2A and 2B, the control unit 20 sets the same area as the operation areas OL and OR as the display areas DL and DR during manual operation, and at the top of the screen of the touch panel display 46. The area is set as a display area DU (two-dot chain line frame). The control unit 20 corrects the rotation of the direction of the display area DU on the touch panel display 46 based on the rotation angle θ. That is, the control unit 20 corrects the direction of the display area DU so that the direction of the display area DU in the vehicle interior space coordinate system is independent of the rotation angle θ of the steering operation unit 45. Then, the control unit 20 sets the display area DU so as to be in contact with the upper side of the touch panel display 46. Even if the steering operation unit 45 is rotated by the rotation angle θ as shown in FIG. 2C, the display area DU is not rotated from the direction of FIG. 2A.

  Here, since the display area DU is set to be in contact with the upper side of the touch panel display 46, there is a high possibility that the display area DU is set to a position higher than the display areas DL and DR. Therefore, during manual operation, the display area DU can be set at a position higher than the gripping positions TL and TR, and the display area DU can be set at a position where there is a low possibility that visual recognition will be hindered by the hand holding the grip portion H. . Further, the display area DU can be set at a position where there is little movement of the line of sight from a state in which the front is visually recognized. Note that the display area DU at the top of the screen is an area for display only, and operations cannot be performed on the display area DU.

  With the function of the display control module 21e, the control unit 20 displays an arrow indicating an operation direction (moving direction of the finger contact position) that can be accepted in the display areas DL and DR (operation areas OL and OR) during manual operation. They are displayed in the display areas DL and DR. Further, the control unit 20 displays the vehicle speed and the steering direction of the vehicle in the display area DU at the top of the screen.

  On the other hand, during the automatic operation, the control unit 20 sets the display area DA in the entire touch panel display 46 as in the operation area OA. In the present embodiment, the control unit 20 displays a map, a vehicle speed, and a steering direction of the vehicle on the display area DA.

  The control unit 20 generates image data of an image to be displayed in the display areas DL, DR, DU, DA by the function of the display control module 21e, and rotates the image data based on the rotation angle θ of the steering operation unit 45. to correct. That is, the control unit 20 corrects the direction of the image data so that the image in the vehicle interior space coordinate system is independent of the rotation angle θ of the steering operation unit 45. Thereby, even if the steering operation unit 45 is rotated, it is possible to make it appear that the images displayed in the display areas DL, DR, DU, DA are not rotated.

  In the present embodiment described above, the operation area OA can be made larger during the automatic operation where the necessity of gripping the steering operation unit 45 is reduced than during the manual operation, and the degree of freedom of operations that can be accepted is increased. Can do. On the other hand, by reducing the operation areas OL and OR during manual driving where the necessity of gripping the steering operation unit 45 is high, it is possible to reduce the possibility of the driver's attention being drawn to the touch panel display 46 by reducing the operation areas OL and OR. . In particular, since the entire touch panel display 46 is set as the operation area OA during automatic driving, the degree of freedom of operations that can be accepted by the touch panel display 46 can be increased during automatic driving.

  Further, during manual operation, by making the operation regions OL and OR follow the gripping positions TL and TR of the steering operation unit 45, the steering operation unit 45 is required to be held during manual operation, which is highly necessary to grip the steering operation unit 45. The operation area can be set at a position where it can be easily operated even if it is held. In addition, since the operation areas OL and OL follow the grip positions TL and TR, even if the grip positions TL and TR of the steering operation unit 45 are changed, it is possible to maintain an easy-to-operate state. In addition, during automatic driving in which the need to visually recognize the front of the vehicle is reduced, a larger variety of displays can be made possible during automatic driving by increasing the display area than during manual driving.

(2) Information input processing:
FIG. 3 is a flowchart of the information input process. The information input process is a process that starts when the accessory power supply of the vehicle is turned on, for example. In addition, turning on the accessory power means that the power of the information input system 10 is turned on. Further, it is assumed that automatic operation has not started when the accessory power source is turned on. That is, the information input process is started during manual operation.

  First, by the functions of the operation area setting module 21d and the display control module 21e, the control unit 20 sets the display areas DL, DR, and DU in the vicinity of the grip positions TL and TR and the upper part of the screen, and the operation area in the vicinity of the grip positions TL and TR. OL and OR are set (step S100). That is, as shown in FIGS. 2A and 2C, the control unit 20 sets the operation areas OL and OR (display areas DL and DR) so that the distances from the gripping positions TL and TR are the shortest. Further, the control unit 20 corrects the directions of the operation areas OL, OR and the display areas DL, DR, DU on the touch panel display 46 based on the rotation angle θ of the steering operation unit 45.

  Next, the control unit 20 monitors the display and operation by the functions of the display control module 21e and the operation reception module 21b (step S110). That is, by the function of the display control module 21e, the control unit 20 generates image data to be displayed in the display areas DL, DR, and DU and corrects the rotation of the image data based on the rotation angle θ of the steering operation unit 45. Output to the touch panel display 46. Further, the control unit 20 monitors the movement of the finger contact position in the operation areas OL and OR by the function of the operation reception module 21b. Here, when the movement of the contact position of the finger in the operation areas OL, OR is detected, the movement vector of the contact position is acquired, and the direction in which the movement vector is rotationally corrected based on the rotation angle θ of the steering operation unit 45. An operation corresponding to is accepted.

  When step S110 is continued for a predetermined period (for example, 1 second), the control unit 20 determines whether or not the automatic operation has been started by the function of the state determination module 21c (step S120). That is, the control unit 20 determines whether or not the state has been shifted to the state where the automatic operation is performed by the function of the automatic operation module 21a by the function of the state determination module 21c.

  When it is not determined that the automatic operation has been shifted (step S120: N), the control unit 20 returns to step S100. Thereby, the image displayed on the display areas DL, DR, and DU can be updated during manual operation. Further, by sequentially performing rotation correction according to the rotation angle θ of the steering operation unit 45, the display areas DL, DR, DU and the operation areas OL, OR can be prevented from rotating in the vehicle interior space coordinate system.

  When it determines with having shifted to automatic driving | operation (step S120: Y), the control part 20 sets operation area OA and display area DA to the whole screen by the function of the operation area setting module 21d and the display control module 21e (step). S130). That is, as illustrated in FIG. 2B, the control unit 20 sets the operation area OA and the display area DA on the entire touch panel display 46.

  Next, the control unit 20 monitors display and operation by the functions of the display control module 21e and the operation reception module 21b (step S140). That is, by the function of the display control module 21e, the control unit 20 generates image data to be displayed in the display area DA, corrects the rotation of the image data based on the rotation angle θ of the steering operation unit 45, and then displays the image data on the touch panel display 46. Output. Further, the control unit 20 monitors the movement of the contact position of the finger in the operation area OA by the function of the operation reception module 21b. Here, when the movement of the contact position of the finger in the operation area OA is detected, the movement vector of the contact position is acquired, and the movement vector corresponds to the direction in which the rotation is corrected based on the rotation angle θ of the steering operation unit 45. The operation to be accepted is accepted.

  When step S140 is continued for a predetermined period (for example, 1 second), the control unit 20 determines whether or not the operation has shifted to manual operation by the function of the state determination module 21c (step S150). That is, the control unit 20 determines whether or not the automatic operation module 21a has shifted to a state where the automatic operation is not performed by the function of the state determination module 21c.

  If it is not determined that the operation has shifted to manual operation (step S150: N), the control unit 20 returns to step S130. Thereby, the image displayed on the display area DA can be updated during automatic operation. On the other hand, when it determines with having shifted to manual operation (step S150: Y), the control part 20 returns to step S100, and performs the process in manual operation.

(3) Other embodiments:
The above embodiment is an example for carrying out the present invention, and various other embodiments can be adopted. For example, the control unit 20 may not set the operation region when the rotation angle θ of the steering operation unit 45 when the steering operation unit 45 travels straight is equal to or greater than a threshold by the function of the operation region setting module 21d. Specifically, during manual operation, the controller 20 operates the operation areas OL and OR and the display area DL when the absolute value of the rotation angle θ from when the steering operation section 45 goes straight is greater than or equal to a threshold value (for example, 70 degrees). , DR may not be set. Not setting the operation areas OL and OR means that no operation is accepted on the touch panel display 46.

  With the above configuration, the driver's attention is attracted to the operation of the touch device in a state where the absolute value of the rotation angle θ of the steering operation unit 45 when traveling straight is equal to or greater than the threshold value and the traveling direction of the vehicle is changing greatly. The possibility can be reduced. Note that the control unit 20 does not set the operation area OA and the display area DA when the absolute value of the rotation angle θ from when the steering operation unit 45 goes straight is greater than or equal to the threshold value even during automatic driving. Good. Further, the rotation angle θ of the steering operation unit 45 is not necessarily the current rotation angle, and may be a rotation angle in the near future, for example. For example, the control unit 20 predicts a steering angle in front of a predetermined distance (for example, 10 m) based on the curve shape of a road section where the vehicle is traveling, and determines the rotation angle of the steering operation unit 45 corresponding to the steering angle. If the absolute value is greater than or equal to the threshold value, the operation area may not be set.

  The content of the operation described above is merely an example, and the content of the operation received by the control unit 20 is not particularly limited. Further, the content displayed by the control unit 20 is not particularly limited. Furthermore, the control unit 20 does not necessarily have to set the entire touch panel display 46 as the operation area OA when the automatic operation is being performed. For example, the control unit 20 may set, as the operation region, a region obtained by enlarging the operation regions OL and OR in the manual operation with a predetermined magnification when shifting to the automatic operation.

  In addition, the operation areas OL and OR during manual operation do not necessarily follow the grip positions TL and TR. For example, during manual operation, when one hand leaves the steering operation unit 45, the control unit 20 may fix the operation areas OL and OR. Furthermore, the control unit 20 may set an operation region that follows the gripping positions TL and TR even during automatic driving.

  Further, the touch device is not necessarily the touch panel display 46. That is, a touch device that does not display on the steering operation unit 45 may be provided. Even in this case, the range in which the finger can be moved on the steering operation unit 45 during manual driving can be limited, so that the possibility of the driver's attention being drawn to the touch device can be reduced.

  The steering operation unit may be an operation unit that is gripped and rotated by the driver for steering, and is not necessarily circular. The moving body steered by the steering operation unit is not necessarily a vehicle, and may be a ship or an aircraft. The touch device may be provided in the steering operation unit, and may be provided in any position of the steering operation unit. For example, a touch device may be provided inside a steering wheel as a steering operation unit, or the steering wheel itself may be a touch device. The operation accepting unit only needs to accept an operation on the touch device, and the type of the accepted operation (tap operation, double tap operation, drag and drop operation, flick operation) is not particularly limited.

  “During automatic driving” means at least a state in which steering is automatically controlled, and may be a state in which not only steering but also acceleration / deceleration is controlled automatically. “During manual operation” means a state where at least steering is not automatically controlled, and acceleration / deceleration may be automatically controlled. The operation area setting unit may increase the operation area for receiving an operation on the touch device when the automatic operation is in progress, compared with the case of manual operation. You may increase kinds. However, it is not always necessary to increase the types of operations accepted by the touch device during automatic driving, and the same operation can be performed easily by enlarging the operation area. The operation region setting unit may notify the driver that the size of the operation region is changed when changing the size of the operation region that receives an operation on the touch device.

  The operation area setting unit may set the entire touch device as the operation area when the automatic operation is being performed. Thereby, during an automatic driving | operation, the freedom degree of operation which can be received with a touch device can be raised.

  Furthermore, the operation region setting unit may detect the grip position of the steering operation unit by the driver and make the operation region follow the grip position when manual driving is in progress. As a result, it is possible to set the operation region at a position where it is easy to operate even when the steering operation unit is held during manual operation where the necessity to hold the steering operation unit is high. Further, since the operation area follows the gripping position, it is possible to maintain an easy-to-operate state even if the gripping position of the steering operation unit changes.

  Further, the operation region setting unit may not set the operation region when the rotation angle of the steering operation unit from the straight traveling time is equal to or greater than the threshold value. This can reduce the possibility that the driver's attention will be attracted by the operation of the touch device in a state where the rotation angle of the steering operation unit from the straight traveling is equal to or greater than the threshold value and the traveling direction of the vehicle is greatly changed.

  In addition, the touch device is a touch panel display, and may further include a display control unit that enlarges a display area for displaying information on the touch device when the automatic operation is in progress than when the manual operation is being performed. As described above, during the automatic driving in which the necessity of visually checking the front of the vehicle is reduced, it is possible to make various displays possible during the automatic driving by increasing the display area as compared with the manual driving.

  Furthermore, the method of guiding the switching to the manual operation at the stop point as in the present invention can be applied as a program or a method. In addition, the system, program, and method as described above may be realized as a single device, or may be realized using components shared with each part of the vehicle, and include various aspects. It is a waste. For example, it is possible to provide a navigation system, an information input system, a method, and a program that include the above devices. Further, some changes may be made as appropriate, such as a part of software and a part of hardware. Furthermore, the invention is also established as a recording medium for a program for controlling the apparatus. Of course, the software recording medium may be a magnetic recording medium, a magneto-optical recording medium, or any recording medium to be developed in the future.
