  FIG. 1 is a block diagram showing an overall configuration of an in-vehicle device operating device according to an embodiment of the present invention. This in-vehicle device operation device is configured by a control unit 1 and an operation unit 2 and operates each in-vehicle device connected to the in-vehicle LAN 3. First, each in-vehicle device connected to the in-vehicle LAN 3 will be described.

  The vehicle speed meter 31 calculates the travel speed of the vehicle based on a detection signal from a vehicle speed sensor (not shown), and displays the calculated travel speed using an analog meter (not shown). The vehicle speed meter 31 transmits the calculated traveling speed to the control unit 1 of the in-vehicle device operating device via the in-vehicle LAN 3. The display of the traveling speed of the vehicle is not limited to the display by an analog meter, and for example, it may be digitally displayed on a liquid crystal panel.

  The audio 32 includes an audio source such as a radio tuner or a CD player, for example. The audio 32 is operated according to an operation signal received from the control unit 1 via the in-vehicle LAN 3. Note that the operation of the audio 32 is not limited to the operation in accordance with the operation signal described above, and can be operated by a switch or a remote controller (not shown) provided in the audio 32.

  As known, the air conditioner 33 adjusts the room temperature so that the temperature in the vehicle interior matches the set temperature by sending out temperature-controlled air into the vehicle interior. In addition, the air conditioner 33 is configured so that the user can manually change the inside / outside air of the air to be sent into the vehicle interior, the air outlet into the vehicle interior, the air flow rate, and the like. An operation signal for the air conditioner 33 is also output from the control unit 1 of the in-vehicle device operation device via the in-vehicle LAN 3. However, the air conditioner 33 is also provided with a dedicated operation switch, and various operations can be performed by the operation switch.

  As is well known, the navigation device 34 detects the current position and traveling direction of the vehicle, and displays a map image around the current position of the vehicle read from the map storage medium together with marks indicating the current position and traveling direction of the vehicle. Not displayed on the display. The navigation device 34 has various navigation functions such as a map scale changing function capable of enlarging or reducing the scale of the display map, a search function for various facilities, and a route guidance function to a destination. Yes.

  The map storage medium described above stores information such as road type, road width, number of lanes, and intersection position of each road in addition to display data for displaying a map image and search data for searching for each facility. ing. Further, the navigation device 34 includes an internal clock for displaying the arrival time at the destination, and can detect the time from the internal clock or a received signal from the GPS.

  And the navigation apparatus 34 transmits information, such as the road classification of the road where the vehicle is drive | working, time information, etc. to the control part 1 of a vehicle equipment operation device via in-vehicle LAN3. Conversely, the control unit 1 transmits an operation signal for operating the navigation device 34 to the navigation device 34. The navigation device 34 is provided with operation members such as a touch switch and a remote controller, and various operations can be performed with the operation members.

  Note that the control unit 1 of the in-vehicle device operation device is configured to output only operation signals of main functions to the audio 32, the air conditioner 33, and the navigation device 34. This is because if the operation of all functions of each in-vehicle device can be executed by the operation unit 2 of the in-vehicle device operation device, the number of operation commands becomes enormous and the operability may be deteriorated. However, for an in-vehicle device with relatively few operation items such as the audio 32 and the air conditioner 33, all the operations of the functions may be performed by the operation unit 2. Moreover, although the audio | voice 32, the air-conditioner 33, and the navigation apparatus 34 were illustrated as an in-vehicle apparatus operated by an in-vehicle apparatus operation apparatus, other wipers, such as a wiper and a window glass opening / closing operation etc. The device to be operated may be used.

  Next, the structure of the control part 1 and the operation part 2 in a vehicle equipment operation device is demonstrated. The operation unit 2 is installed on a steering wheel (not shown) of the vehicle so that the operation on each in-vehicle device can be easily performed without hindering the driving operation of the user's vehicle.

  The external communication unit 11 communicates with each of the vehicle speed meter 31, the audio 32, the air conditioner 33, and the navigation device 34 via the in-vehicle LAN 3. Specifically, vehicle speed information is received from the vehicle speed meter 31 and information such as road type and time information is received from the navigation device 34. Further, the external communication unit 11 transmits an operation signal for operating the main functions of the in-vehicle devices of the audio 32, the air conditioner 33, and the navigation device 34 to the corresponding devices via the in-vehicle LAN 3.

  The storage unit 12 stores operation commands for operating main functions of the audio 32, the air conditioner 33, and the navigation device 34. Further, the storage unit 12 stores a plurality of pieces of information related to command sets in which a plurality of operation commands are grouped. The plurality of command sets are initially set in advance by the user or as default data, and stored in the storage unit 12. Furthermore, the plurality of command sets correspond to any one of the traveling situations of the vehicle classified into a plurality, and the correspondence relationship is also initially set.

  FIG. 2 shows an example of the command set. In the example shown in FIG. 2, the traveling state of the vehicle is classified into four types, for example, when traveling on a general road, traveling on an expressway, traveling at night, and traveling on a traffic jam, and command sets A to D are respectively Are associated with the driving situation. The operation commands included in each of the command sets A to D are initially set by the user or as default data so as to include an operation command that is considered to be most frequently used in the corresponding driving situation.

  For example, when driving on a general road, there are many opportunities to enlarge / reduce the map to check the surrounding facilities and traveling direction of the vehicle, and there are many users who enjoy audio while driving. There are many opportunities for operations. Accordingly, the command set A associated with traveling on a general road includes the operation command (number 1) for enlarging the map displayed on the navigation device 34, the operation command (number 2) for reducing the map, and the radio tuner channel of the audio 32. The operation command (number 3) for switching and the operation command (number 4) for switching the source of radio / CD in the audio 32 are set.

  Further, the storage unit 12 stores the actual traveling state of the vehicle by road type (for example, urban general road, suburban general road, highway, etc.), time zone (for example, 6-10 o'clock commuting time zone, 17:00 daytime hours, 17: 00-20: 00 return time zones, and 20: 00-20: 00 night time zones), and (average) travel speed of vehicles (for example, 0-10 km / H for traffic jams, normal A selection number table is provided for counting and storing the number of times the command sets A to D are assigned to the operation unit 2 while classifying them by 10 to 40 km / H for traveling and 40 km / H or more for traveling at high speed). .

  FIG. 3 shows an example of the selection number table set for the urban general road. As shown in FIG. 3, the number of times assigned to the operation unit 2 of each command set A to D is stored for each situation classified by the average traveling speed and the time zone in the selection table of the general roads in the urban area. ing. In the state where the command sets A to D are assigned to the operation unit 2, the counter of the corresponding command sets A to D is counted up when the in-vehicle device is operated by the operation command at least once. .

  The traveling state determination unit 13 determines whether the actual traveling state of the vehicle is a general road traveling time, based on the traveling speed information of the vehicle received by the external communication unit 11 via the in-vehicle LAN 3, the road type information on which the vehicle is traveling, and time information. It is determined whether the vehicle falls on a highway driving, a night driving, or a traffic jam. Even when driving on a general road or on an expressway, it is determined that the vehicle is traveling at night when it is at night. Further, when the average traveling speed of the vehicle belongs to a predetermined low speed range (0 to 10 km / H), it is determined that the vehicle is traveling in a traffic jam. The average traveling speed is calculated by, for example, averaging the traveling speeds for the past 5 minutes. Furthermore, even when the vehicle is actually traveling on a general road, when the average traveling speed of the vehicle is relatively fast (40 km / H), such as a general road in a suburb, it is determined that the vehicle is traveling on a highway. Is done.

  The internal communication unit 14 is a unit that controls communication between the control unit 1 and the operation unit 2, and a command set assigned to the operation unit 2 with respect to the operation unit 2 and information regarding operation commands included in the command set Display data and code signals are transmitted. Also, the operation unit 2 replaces the operation signal of the operated operation command, the change signal instructing the change of the command set assigned to the operation unit 2, and the operation command in the command set with another operation command. A replacement signal is transmitted.

  The control unit 15 plays a central role in the control processing in the control unit 1. For example, based on the actual running situation of the vehicle determined by the running situation unit 13, information on the command set corresponding to the running situation is obtained. The data is read from the storage unit 12 and transmitted to the operation unit 2 via the internal communication unit 14. Moreover, when an operation signal is acquired from the operation unit 2 via the internal communication unit 14, the operation signal of the in-vehicle device is transmitted to the corresponding in-vehicle device via the external communication unit 11. In that case, 1 is added to the counter of the command set that includes the operation command that transmitted the operation signal in the classification portion corresponding to the actual traveling state of the vehicle in the selection number table stored in the storage unit 12.

  For example, when the vehicle is traveling on an urban general road, the time is 7 am, and the average traveling speed of the vehicle is 30 km, the operation command included in the command list D is operated, and the operation unit 2 Assume a situation where an operation signal is transmitted. In this case, the value of the counter of the command set D is incremented by 1 in the classification part of the selection number table shown in FIG. 3 where the time zone is 6-10 o'clock and the average traveling speed is 10-40 km.

  Furthermore, whenever the control unit 15 receives a change signal indicating a request for changing the command set assigned to the operation unit 2, the control unit 15 refers to the classification portion corresponding to the traveling state of the vehicle in the selection number table stored in the storage unit 12. Then, command sets are selected and assigned to the operation unit 2 in descending order of the counter value among other command sets excluding the command set already assigned to the operation unit 2.

  For example, in a situation where the command set D is assigned to the operation unit 2 when the vehicle is traveling on a city road and the time is 7 am and the average traveling speed of the vehicle is 10 km or less, Assume a situation in which a change signal indicating a command set change request is acquired from the unit 2. In this case, the counter values of the command sets A to C other than the command set D in the classification part of the selection number table shown in FIG. 3 where the time zone is 6-10 o'clock and the average traveling speed is 10-40 km are Referenced. In this case, since the counter value of the command set C is the largest, the command set C is allocated to the operation unit 2 instead of the command set D. When the largest counter value is stored for a plurality of command sets, any command set may be assigned to the operation unit 2.

  Further, when receiving the operation command replacement signal and the signal indicating the operation command to be replaced from the operation unit 2, the control unit 15 reads out all operation commands stored in the storage unit 12 and sequentially transmits them to the operation unit 2. When one of the operation commands is selected by the user, processing for replacing the operation command in the command set with the selected operation command is performed. That is, the control unit 15 rewrites information on the command set in the storage unit 12 in order to change the operation command included in the command set.

  For example, when the command list A is assigned to the operation unit 2 and the radio / CD switching operation command is received as the replacement signal and the operation command to be replaced from the operation unit 2, the control unit 15 stores it in the storage unit 12. All the operation commands that have been read are read out and sequentially transmitted to the operation unit 2. When any operation command is selected by the user, the radio / CD switching operation command listed in the command list A is replaced with the selected operation command.

  Next, the configuration of the operation unit 2 of the present embodiment will be described. The display panel 21 is composed of, for example, a small liquid crystal display, and is a display data indicating a command set assigned to the operation unit 2. ), The names of the operation commands included in the command set, the names of the operation commands received from the control unit 1 during the operation command replacement process, and the like are displayed. As a result, the user can grasp the command set assigned to the operation unit 2, the operation commands included in the command set, etc. at a glance.

  The change switch 22 includes, for example, a push button switch, and transmits a change signal indicating a change request for a command set and a replacement signal indicating a request for replacing an operation command included in the command set to the control unit 1 in accordance with the time of pressing. To do. That is, by depressing the change switch 22 for a predetermined time (for example, 3 seconds) or less, information indicating the command set assigned to the operation unit 2 (traveling state of the vehicle) displayed on the display panel 21 is changed. An example in which information indicating the command set is changed is shown in FIG. As shown in FIG. 4, every time the change switch 22 is pressed for a short time, a command assigned to the operation unit 2 when driving on an ordinary road → when driving on an expressway → when driving at night → when driving on a traffic jam → when driving on a general road. The set is changed in order.

  On the other hand, by continuing to hold down the change switch 22 for a predetermined time or longer, the operation command replacement processing mode is set, and the operation commands included in the preset command sets A to D can be replaced with other operation commands. It becomes possible. The operation command replacement process will be described later.

  The designation switch 23 is a composite switch that can be rotated and pressed. When information indicating one of the command sets A to D is displayed on the display panel 21, when the designation switch 23 is rotated or pressed in any direction, the displayed command sets A to D are displayed. Are displayed on the display panel 21 in accordance with the command number. If the change switch 22 is pressed while the operation command is displayed on the display panel 21, the display state of the command set is restored.

  In the operation command display state, each of the operation commands included in the command set assigned to the operation unit 2 can be sequentially displayed on the display panel 21 by rotating the designation switch 23 in either the left or right direction. it can. In FIG. 5, when the command set A corresponding to traveling on a general road is assigned to the operation unit 2, the operation command displayed on the display panel 21 is changed by rotating the designation switch 23 in the left-right direction. An example is shown. As shown in FIG. 5, by rotating the designation switch 23 in the right direction, the display of operation commands is sequentially switched from the map enlargement operation command of command number 1 to the radio / CD switching operation command of command number 4. . Conversely, the display of the operation command is switched from the radio / CD switching operation command of command number 4 to the map enlargement operation command of command number 1 by rotating the designation switch 23 in the left direction.

  When any operation command is displayed on the display panel 21, the user can instruct the operation of the in-vehicle device by the operation command by pressing the designation switch 23. In this case, the operation unit 2 outputs an operation signal corresponding to the operation command being displayed on the display panel 21 to the control unit 1.

  During replacement processing of operation commands included in a preset command set, an operation command to be deleted from the command set and an operation command to be newly added are specified by the designation switch 23. That is, when a replacement signal is output by pressing the change switch 22, the operation command replacement processing mode is set. First, using the change switch 22 and the designation switch 23, an operation command to be erased is displayed on the display panel 21. Display. When the designation switch 23 is pressed, the operation command displayed on the display panel 21 is designated as a command to be deleted.

  Next, the control unit 1 reads out the operation commands from the storage unit 12 and sequentially transmits them to the operation unit 2 so that the user can select an operation command to be newly included in the command list. The transmitted operation command is displayed on the display panel 21. Then, the operation command displayed on the display panel 21 is switched by the rotation operation of the designation switch 23, and the operation command to be newly added is designated by the pressing operation.

  Next, control processing executed in the in-vehicle device operation apparatus of the present embodiment will be described based on the flowchart of FIG.

  In step S101, the vehicle traveling speed, the road type during traveling of the vehicle, and time information transmitted from each in-vehicle device are received as information indicating the traveling state of the vehicle. In step 102, the traveling state determination unit 13 determines whether the traveling state of the vehicle is a general road traveling, an expressway traveling, or a night traveling based on the received traveling speed of the vehicle, the type of road on which the vehicle is traveling, and time information. It is determined whether the vehicle falls under a traffic jam. Then, the control unit 15 selects a command set corresponding to the determined traveling situation and reads it from the storage unit 12. At this time, referring to the classification portion corresponding to the determined running situation in the selection number table set for each road type, if the number of selections of each command set is stored, the command set indicating the highest number of selections is selected. select. If the number of selections for each command set has not yet been stored, the command set is selected based on the relationship between the initially set traveling state and the command set.

  In step 103, the selected command set is assigned to the operation unit 2 by the control unit 15. In this command set allocation process, display data and a code signal indicating a command set and an operation command included in the command set are given to the operation unit 2. Thereby, the operation unit 2 can display a command set and an operation command on the display panel 21 based on the display data. Furthermore, when the operation switch 2 is operated to press the designation switch 23, the operation signal including the code signal is transmitted to the control unit 1, whereby the control unit 1 is instructed to perform any operation command. Can be recognized.

  In step S104, it is determined whether or not the change switch 22 or the designation switch 23 has been operated. If it is determined that any switch has been operated, the process proceeds to step S105. If it is determined that any switch has not been operated, the process returns to step S101.

  In step S105, it is determined whether or not the change switch 22 has been pressed. If it is determined that the pressing operation has been performed, it is further determined in step S106 whether the pressing operation has been performed for 3 seconds or more. If it is determined that the pressing operation has been performed for 3 seconds or more, as described above, this corresponds to the output of a replacement signal indicating a replacement request for the operation command by the user, and thus the process proceeds to step S107 and the operation command replacement process Execute. The operation command replacement process will be described in detail later.

  On the other hand, when it is determined in step S106 that the pressing operation of the change switch 22 is a short time of 3 seconds or less, this corresponds to the output of a change signal indicating a change request for the command sets A to D by the user. In step S108, the command sets A to D assigned to the operation unit 2 are changed. At the time of changing the command sets A to D, as described above, it is already assigned to the operation unit 2 with reference to the classification portion corresponding to the traveling state of the vehicle in the selection number table stored in the storage unit 12. A command set having a large selection number is selected from other command sets excluding the command set and assigned to the operation unit 2. If the number of selections has not yet been stored, the command set selection order is arbitrary.

  If it is determined in step S105 that the change switch 22 has not been pressed, the process proceeds to step S109. In step S109, it is determined whether an operation command display instruction has been issued. That is, it is determined whether or not the instruction switch 23 has been rotated or pressed while the command sets A to D are displayed on the display panel 21. If it is determined that an operation command display instruction has been issued, the process proceeds to step S110. In step S110, an operation command is displayed. That is, the operation commands included in the command sets A to D displayed when the operation command display instruction is given are displayed according to the command number.

  Next, in step S111, it is determined whether or not the instruction switch 23 has been rotated. As described above, the rotation operation of the instruction switch 23 indicates an operation command change request. For this reason, when it is determined that the instruction switch 23 has been rotated, the process proceeds to step S112, and the next operation command included in the command sets A to D assigned to the operation unit 2 is displayed.

  On the other hand, if it is determined in step S111 that the instruction switch 23 has not been rotated, the process proceeds to step S113 to determine whether or not the instruction switch 23 has been pressed. As described above, the pressing operation of the instruction switch 23 indicates an operation instruction request by an operation command. For this reason, when it is determined that the instruction switch has been pressed, the operation unit 2 transmits an operation signal to the control unit 1 in step S114. In response to this, the control unit 1 transmits an operation signal to the corresponding in-vehicle device via the in-vehicle LAN 3. Further, in step S115, since the operation by the operation command has been performed, the selection number table of the command sets A to D is updated. That is, the number of selections of the command set including the operated operation command is increased by 1 in the classification portion corresponding to the traveling state of the vehicle in the selection number table.

  If it is determined in step S113 that the instruction switch 23 has not been pressed, the process proceeds to step S116. In step S116, it is determined whether or not the change switch 22 has been pressed to determine whether or not the user has instructed the return to the command set display state. If it is determined in this determination process that the change switch 22 has been pressed, the process proceeds to step S117, the command set is displayed on the display panel 21, and the process returns to step S105. On the other hand, if it is determined that the pressing operation of the change switch 22 has not been performed, the process returns to step S111 in order to wait for any switch operation.

  If any switch operation is not performed after a predetermined time (for example, 30 seconds) even if any switch operation is performed, “Yes” is determined in step S118. As a result, the processing returns to step S101.

  By the processing described above, a command set including an operation command that is likely to be used can be assigned to the operation unit 2 for each traveling situation of the vehicle. That is, a command set to be assigned to the operation unit 2 is selected by referring to the correspondence relationship between the initially set traveling state and the command set, or the selection number table indicating the usage record of each command set in each traveling state. Therefore, it is possible to automatically assign an operation command having a high possibility of being used to the operation unit 2 in accordance with a change in the traveling state of the vehicle.

  In addition, once any command set A to D is assigned to the operation unit 2, if the operation command that the user wants to operate is not included, the user sets the command set A to D assigned to the operation unit 2. D can be changed. Thereby, even when the command set A to D including the desired operation command that the user wants to operate is not allocated to the operation unit 2, the command set A to D including the desired operation command is surely allocated to the operation unit 2. be able to.

  As described above, since the command sets A to D assigned to the operation unit 2 can be arbitrarily changed by the user, the usage history information of the command sets A to D actually used in each driving situation, that is, The number of selections in the selection number table serves as an index indicating the high availability of each command set A to D as it is.

  Next, operation command replacement processing will be described with reference to the flowchart of FIG. When the start of the operation command replacement process is instructed by pressing the change switch 23 for 3 seconds or longer, first, in step S201, it is further determined whether or not the change switch 22 has been pressed. If the change switch 22 is pressed, the process proceeds to step 202, where another command set is displayed instead of the command set currently displayed on the display panel 21. In this way, the command set including the operation command to be deleted is selected in the replacement process. If the change switch 22 has not been pressed, the process proceeds to step 203.

  In step S203, it is determined whether or not an operation command display instruction has been issued. That is, it is determined whether or not the instruction switch 23 has been rotated or pressed while the command sets A to D are displayed on the display panel 21. If it is determined that an operation command display instruction has been issued, the process proceeds to step S204. In step S204, an operation command is displayed. That is, the operation commands included in the command sets A to D displayed when the operation command display instruction is given are displayed according to the command number.

  Next, in step S206, it is determined whether or not the instruction switch 23 has been rotated. If it is determined that the instruction switch 23 has been rotated, the process proceeds to step S207, and the next operation command included in the command sets A to D assigned to the operation unit 2 is displayed. On the other hand, if it is determined in step S206 that the rotation operation of the instruction switch 23 has not been performed, the process proceeds to step S208 to determine whether or not the instruction switch 23 has been pressed. If it is determined in step S208 that the instruction switch 23 has not been pressed, the process proceeds to step S209.

  In step S209, based on whether or not the change switch 22 has been pressed, it is determined whether or not the user has instructed the return to the display state of the command sets A to D. If it is determined in this determination process that the change switch 22 has been pressed, the process proceeds to step S210, command sets A to D are displayed on the display panel 21, and the process returns to step S201. On the other hand, if it is determined that the change switch 22 has not been pressed, the process returns to step S206 to wait for any switch operation.

  On the other hand, if it is determined in step S208 that the instruction switch has been pressed, the process proceeds to step S211 where an erase command is designated. That is, the control unit 1 specifies an operation command for which an operation signal is output by pressing the instruction switch 23 as an operation command to be deleted from the command lists A to D.

  In step S212, the control unit 1 stores the operation command to be newly added to the command sets A to D in the storage unit 12 in order to allow the user to specify an operation command to be newly added to the command sets A to D. The display data and code data of the operation command that has been sent are transmitted. In response to this, the operation unit 2 receives the display data and the code data of the operation command, and displays the name of the operation command on the display panel 21 based on the display data.

  In a succeeding step S213, it is determined whether or not the instruction switch 23 is rotated. The rotation operation of the instruction switch 23 indicates a request for changing an operation command by the user. For this reason, when it is determined that the rotation operation of the instruction switch 23 has been performed, the process returns to step S212 to receive and display display data of another operation command.

  If it is determined in step S213 that the instruction switch 23 has not been rotated, the process proceeds to step S214. In step S214, it is determined whether or not the instruction switch 23 has been pressed. The operation of pressing the instruction switch 23 is performed in order to specify an operation command to be newly added. Therefore, if it is determined that the instruction switch 23 has been pressed, the operation command displayed on the display panel 21 when the instruction switch 23 is pressed in step S215 is the operation to be newly added. Specified as a command.

  In step S216, the contents of the command set stored in the storage unit 12 are rewritten so that the operation command specified as the erase command is replaced with the operation command specified as the additional command.

  If no switch operation is performed for a predetermined time (for example, 30 seconds) after the operation command rewriting process is started, a determination of “Yes” is made in step S205. The operation command rewriting process is terminated.

  With the above-described processing, it is possible to change any operation command included in each command set according to the needs and preferences of each user.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. .

  For example, in the above-described embodiment, the operation unit 2 is configured such that the name of the command set or the operation command is displayed on the display panel 21. However, the name of the command set or operation command may be notified to the user by other means such as graphic display, display color change, sound change or voice.

  Furthermore, in the above-described embodiment, the traveling state of the vehicle is classified according to the type of road on which the vehicle is traveling, the traveling speed of the vehicle, and the time, but other parameters may be employed. For example, weather information (for example, which can be acquired by a wiper signal), day of the week or date information, steering angle indicating the driving state of the vehicle, acceleration, yaw rate, turn signal, etc. may be used as other parameters. Further, information such as road width, estimated travel distance to the destination, road / private land (for example, parking lot) identification information, one-way road, time to reach the destination, distance to the intersection, etc. from the navigation device 34 May be acquired and used as the other parameters described above. As described above, by subdividing the traveling state of the vehicle, a command set that is likely to be used by the user can be assigned to the operation unit 2 with higher probability.

  In the above-described embodiment, in the initial setting, command sets corresponding to four driving situations (when driving on a general road, driving on a highway, driving at night, and driving on a traffic jam) are prepared. However, the vehicle driving conditions are not limited to the above four. For example, when a vehicle is traveling in an urban area even when it is a general road (when traveling in an urban area), the vehicle is traveling in a suburb. It is possible to arbitrarily increase or decrease the setting of the traveling state, such as distinguishing from the case where the vehicle is traveling (when traveling in the suburbs).

  Furthermore, in the above-described embodiment, an example in which four command sets are set corresponding to four driving situations has been described, but a larger or smaller number of command sets may be set than the driving situation. Further, as information for identifying a command set, in addition to using the classified traveling situation as in the above-described embodiment, for example, each command set is identified and displayed by giving a number or an arbitrary name. May be.
