  The entire touch operation panel unit 23 is a transparent body, and transmits light from an image displayed on the liquid crystal image display panel unit 22. As a result, the image displayed on the liquid crystal image display panel unit 22 is visually recognized through the contact operation panel unit 23. When the contact operation is performed on the contact operation panel unit 23, the contact operation panel unit 23 supplies operation output data DTU corresponding to the contact operation to the operation control unit 30.

  In addition to the current position data DP from the current position detection unit 13 and the set route data DCS from the travel route setting unit 17, the voice data forming unit 19 is also supplied with map data DM from the map data memory unit 16. Furthermore, traffic information data DTR and an operation control signal CAG from the operation control unit 30 are supplied. Under such circumstances, the voice data forming unit 19 sets the setting route data DCS based on the current position data DP, the setting route data DCS, the map data DM, and the traffic information data DTR in accordance with the operation control signal CAG. The voice guidance data DAG for voice guidance according to the traffic information represented by the traffic information represented by the traffic information represented by the traffic information data DTR is further taken, Voice guidance data DAG obtained from the forming unit 19 is supplied to the voice signal forming unit 24.

  In the audio signal forming unit 24, an audio signal SAG based on the audio guidance data DAG is formed, and the audio signal SAG is supplied to the audio generating unit 25. As a result, the voice generator 25 generates a voice output for voice guidance based on the voice guidance data DAG formed in the voice data forming unit 19.

  An input operation unit 34 and a program data memory unit 35 are connected to the operation control unit 30. The input operation unit 34 includes various adjustment operation buttons, a control switch, a data input keyboard, and the like. For example, when a manual operation is performed by a user, the input operation unit 34 sends out the input data DX and sends it to the operation control unit 30. To supply. The program data memory unit 35 stores an operation program in advance, and supplies program data DPR representing the operation program to the operation control unit 30 as necessary.

  Further, the current position data DP from the current position detection unit 13, the set route data DCS sent by the travel route setting unit 17, and the map data DM from the map data memory unit 16 are also supplied to the operation control unit 30.

  Then, the operation control unit 30 determines the travel schedule route from the specific departure point to the specific destination for the vehicle mounted on the travel route setting unit 17 according to the content of the input data DX supplied from the input operation unit 34. Based on the received information signal STR supplied from the decoder unit 33, the route setting operation state for performing the setting, the voice guidance operation state for enabling the voice output from the voice generation unit 25 to be output as voice guidance, and the like. In accordance with the contents of the traffic information data DTR obtained in this way, a route resetting operation state is performed in which the travel route setting unit 17 resets the planned travel route for changing the planned travel route once set for the mounted vehicle.

  When the operation control unit 30 takes the path setting operation state, the program data DPR is read from the program data memory unit 35 and taken into the operation control unit 30, and the operation for the path setting operation represented by the program data DPR in the operation control unit 30. As the program operates, the operation control unit 30 assumes that the input data DX from the input operation unit 34 according to the input operation by the user represents a specific destination, route search conditions, etc. that the mounted vehicle should reach. Is taken in. In the operation control unit 30, destination data based on the input data DX, route search condition data, and the like are obtained by the route setting data generating unit, and received information supplied from the decoder unit 33 by the traffic information data generating unit. Traffic information data DTR based on the signal STR is obtained. Then, the route setting data generating means forms the route setting data DRD including the destination data and route search condition data obtained thereby and the traffic information data DTR obtained by the traffic information data generating means. Is done.

  In parallel with this, the operation control unit 30 supplies the operation control signal CRS to the travel route setting unit 17 so that the travel route setting unit 17 is in an activated state. The reference position data DZ from the generating means is sent to the current position detector 13. Under such circumstances, the route setting data DRD sent from the route setting data generating means in the operation control unit 30 is supplied to the travel route setting unit 17.

  Accordingly, in the travel route setting unit 17, based on the map data DM from the map data memory unit 16, the current position data DP from the current position detection unit 13, and the route setting data DRD from the operation control unit 30, A planned travel route from the departure point which is the position of the mounted vehicle represented by the reference position data DZ to a specific destination represented by the destination data is set, and set route data DCS relating to the set planned travel route is formed. At this time, for example, when the traffic information data DTR included in the route setting data DRD represents traffic information related to a road section where the vehicle should be avoided in a situation where traffic congestion has occurred, The planned travel route set in the route setting unit 17 does not include a portion corresponding to a road section where the travel of the vehicle should be avoided. Then, the set route data DCS representing the set new route is supplied to the display data forming unit 18, the audio data forming unit 19, and the operation control unit 30.

  When the operation control unit 30 takes the voice guidance operation state, the program data DPR is read from the program data memory unit 35 and is taken into the operation control unit 30, and the operation control unit 30 displays the voice guidance represented by the program data DPR. Under the operation program for operation, the traffic information data generating means obtains the traffic information data DTR based on the received information signal STR supplied from the decoder unit 33, and the traffic control data 30 is obtained from the operation control unit 30. The operation control signal CAG is supplied to the audio data forming unit 19. Accordingly, the voice data forming unit 19 performs an operation of forming voice guidance data DAG based on the current position data DP, the set route data DCS, the traffic information data DTR, and the map data DM in accordance with the operation control signal CAG. As a result, as described above, the voice generation unit 24 outputs a voice output as voice guidance based on the voice guidance data DAG formed in the voice data forming unit 19.

  Furthermore, when the operation control unit 30 takes the route resetting operation state, the set route data DCS representing the planned travel route already set in the travel route setting unit 17 is supplied to the display data forming unit 18 and the image display is performed. In the liquid crystal image display panel section 22 in the section 21, for example, as shown in FIG. 3, an image representing a road map 41, an image representing the current position 42 of the mounted vehicle superimposed thereon, and a destination 43 for the mounted vehicle are displayed. The VICS signal SVS received by the VICS signal receiving antenna 31 and the VICS signal receiving unit 32 on the basis of the displayed image, the image of the planned traveling route 44 set for the mounted vehicle, and the like is the planned traveling route. It is assumed that the section where the mounted vehicle proceeds on the road along the road 44 is in a specific situation.In certain cases of road sections in such cases, for example, traffic may be caused at least because of traffic jams, situations under construction, situations that are dangerous or difficult to pass due to damage, and obstacles. The road sections that are either dangerous or difficult situations and dangerous or difficult to pass due to weather conditions should be included, and the road sections in such specific situations should avoid the onboard vehicles traveling It becomes a road section.

  The occurrence of such a case means that the travel route setting unit 17 sets the travel planned route 44 for the mounted vehicle, and after the mounted vehicle starts traveling according to the travel planned route 44, it follows the travel planned route 44. The section where the onboard vehicle proceeds is in a specific situation.

  At this time, information represented by the traffic information data DTR obtained based on the reception information signal STR supplied from the decoder unit 33 by the traffic information data generating means in the operation control unit 30 is This indicates that the section to be progressed is in a specific situation. Then, the operation control unit 30 supplies the traffic information data DTR obtained by the traffic information data generating means to the display data forming unit 18, and the set route data DCS from the travel route setting unit 17 from the display data forming unit 18. Based on the traffic information data DTR from the operation control unit 30, the part corresponding to the road section in the specific situation represented by the traffic information data DTR in the planned travel route represented by the set route data DCS is represented by the specific situation. Thus, image display data DSP for displaying in accordance with the above is obtained. Thereby, in the liquid crystal image display panel unit 22 in the image display unit 21, for example, as shown in FIG. 4, a portion of the planned travel route 44 displayed as an image corresponds to a road section in a specific situation in the route. In 45, for example, a display according to a specific situation, which is displayed with a thick line, is performed.

  Under such circumstances, when the occupant of the mounted vehicle desires to change the planned travel route 44 so as not to include the portion 45 corresponding to the road section in a specific situation, the mounted vehicle As shown in FIG. 1, the scheduled traveling route 44 displayed according to a specific situation on the touch operation panel unit 23 arranged on the liquid crystal image display panel unit 22 in the image display unit 21 as shown in FIG. The contact operation is performed on a part corresponding to a part of (a part 45 corresponding to a road section in a specific situation). For example, as shown in FIG. 1, such a contact operation corresponds to a part of the planned travel route 44 displayed according to a specific situation on the touch operation panel unit 23 (corresponding to a road section in a specific situation). The portion corresponding to the portion 45) is traced by the tip portion of the finger, and then the portion corresponding to the point 46 on the scheduled travel route 44 other than that portion is touched with the tip portion of the finger, which is an easy and simple operation. .

  When such a contact operation on the contact operation panel unit 23 is performed, operation output data DTU corresponding to the contact operation is sent from the contact operation panel unit 23 and supplied to the operation control unit 30. The operation output data DTU includes a portion 45 corresponding to a road section in a specific situation on the planned travel route 44 on the road map 41 displayed on the liquid crystal image display panel unit 22 and a planned travel route other than that portion. The position of the point 46 on 44 is shown.

  In the operation control unit 30 supplied with the operation output data DTU from the contact operation panel unit 23, the route setting data generating means is already set by the travel route setting unit 17 in accordance with the operation output data DTU. The planned travel route represented by the set route data DCS, that is, the planned travel route 44 displayed in the image on the liquid crystal image display panel unit 22 is displayed, for example, from the beginning of the portion 45 corresponding to the road section in the specific situation. Corresponds to a region from the start end of the portion traced by the tip of the finger on the touch operation panel unit 23 to a point touched by the tip of the finger. The part corresponding to the road section in a specific situation is not included by replacing the part of the planned travel route 44 with another route. Newly forming the data DRD for routing to change shall not include replacing the route. The operation control unit 30 supplies the route setting data DRD and the operation control signal CRS newly formed by the route setting data generating unit in this way to the travel route setting unit 17, and Re-establishment of the planned travel route for changing the planned travel route that has been newly set and already set according to the route setting data DRD is performed.

  In accordance with the operation control signal CRS, the travel route setting unit 17 that resets the newly planned travel route according to the route setting data DRD is a road section in a specific situation in the planned travel route 44 before the change. The portion corresponding to the road section in a specific situation is not included by replacing the portion from the start end of the portion 45 corresponding to the point 45 to the point 46 on the planned travel route 44 other than that portion with another route. Is replaced with another route, and a new planned travel route is set. Then, the travel route setting unit 17 sends the set route data DCS representing a new planned travel route that is changed and does not include a portion corresponding to a road section in a specific situation, and displays it as display data. The data is supplied to the forming unit 18, the audio data forming unit 19, and the operation control unit 30. Thereby, in the liquid crystal image display panel unit 22 in the image display unit 21, for example, as shown in FIG. 5, from the beginning of the portion 45 corresponding to the road section in a specific situation in the planned travel route 44 before the change. An image of a new planned travel route 44 ′ that is not included by replacing the portion reaching the point 46 on the planned travel route 44 other than the portion with another route is displayed superimposed on the image of the road map 41. The

  Thus, according to the example shown in FIG. 2, the travel route setting unit 17 sets the travel planned route for the mounted vehicle, and after the mounted vehicle starts traveling according to the travel planned route, As shown in FIG. 1, when the section where the mounted vehicle travels on the road along the road is in a specific situation and the vehicle should be avoided, as shown in FIG. In the contact operation panel unit 23 arranged to overlap the liquid crystal image display panel unit 22 in the unit 21, only a contact operation is performed on a part corresponding to a part of the planned travel route displayed according to a specific situation. With the easy and simple operation, the planned driving route for the installed vehicle that has already been set includes the road section where the vehicle should be avoided under certain conditions. It will be able to change to those without.

  In the liquid crystal image display panel unit 22 in the image display unit 21, for example, as shown in FIG. 3, an image representing a road map 41, an image representing the current position 42 of the mounted vehicle superimposed thereon, and a destination for the mounted vehicle The VICS signal SVS received by the VICS signal receiving antenna 31 and the VICS signal receiving unit 32 while the image representing 43 and the image of the planned traveling route 44 set for the mounted vehicle are displayed. In the case where there is a section where the mounted vehicle travels on the road along the planned route 44 in a specific situation and there are a plurality of such road sections intermittently at a relatively short distance, an image display unit In the liquid crystal image display panel unit 22 in FIG. 21, for example, as shown in FIG. A plurality of portions 45a corresponding to the road section in a specific situation in les in 45b and 45 c, for example, are displayed by thick lines, are those in which the display according to the particular circumstances is made.

  In such a case, an onboard vehicle occupant wishing to change the planned travel route 44 so as not to include a plurality of portions 45a, 45b and 45c corresponding to a road section in a specific situation is shown in FIG. As shown in FIG. 5, a part of the planned travel route 44 on the touch operation panel unit 23 laid over the liquid crystal image display panel unit 22 in the image display unit 21 is displayed according to a specific situation (specific The contact operation is performed on the portions corresponding to the plurality of portions 45a, 45b and 45c) corresponding to the road sections in the situation. Such a contact operation is, for example, as shown in FIG. 6, a range over all of the plurality of portions 45 a, 45 b and 45 c in the planned travel route 44 displayed according to a specific situation on the contact operation panel unit 23. This is an easy and simple operation in which a portion corresponding to is traced with the tip portion of the finger and then the portion corresponding to the point 46 on the planned travel route 44 outside the range is touched with the tip portion of the finger.

And the part from the beginning of the range over the entire range 45c to the point 46 on the planned travel route 44 other than that range is replaced with another route so that it corresponds to a road section in a specific situation. A new scheduled travel route is set in which the portion to be replaced is replaced with another route and is not included. As a result, in the liquid crystal image display panel unit 22 in the image display unit 21, as shown in FIG. 7, for example, a plurality of portions 45 a and 45 b corresponding to road sections in a specific situation on the planned travel route 44 before the change. And an image of a new planned travel route 44 ′ that is not included by replacing the part from the start end of the range over the entire range 45c to the point 46 on the planned travel route 44 other than that range by another route, It is displayed superimposed on the image of the road map 41.

  Thus, according to the example shown in FIG. 2, the travel route setting unit 17 sets the travel planned route for the mounted vehicle, and after the mounted vehicle starts traveling according to the travel planned route, Even when a plurality of sections on the road along the road where the vehicle is traveling intermittently becomes a specific situation and the vehicle should be avoided from traveling, As shown in FIG. 5, a portion corresponding to a part of the planned travel route on which a display corresponding to a specific situation is displayed in the contact operation panel unit 23 arranged to overlap the liquid crystal image display panel unit 22 in the image display unit 21. With a simple and easy operation that only requires the contact operation on the vehicle, the planned travel route for the installed vehicle should be avoided under certain conditions. It will be able to change that does not contain a plurality of road sections continuous to intermittent, which is a state.

  The operation control unit 30 shown in FIG. 2 that performs the control operation as described above is configured using, for example, a microcomputer. FIG. 8 is a flowchart showing an example of an operation program executed when the microcomputer constituting the operation control unit 30 takes the path resetting operation state.

  In the operation program shown in the flowchart of FIG. 8, the set route data DCS representing the planned travel route already set in the travel route setting unit 17 is supplied to the display data forming unit 18, and the liquid crystal image display in the image display unit 21 is performed. In the panel unit 22, for example, as shown in FIG. 3, an image representing a road map 41, an image representing a current position 42 of the mounted vehicle superimposed thereon, an image representing a destination 43 for the mounted vehicle, and a mounted The process starts when an image of the scheduled travel route 44 set for the vehicle is displayed.

  After the start, in step 51, whether or not the traffic information data DTR formed by the traffic information data generating means represents a road section in a specific situation that is the destination of the onboard vehicle on the road along the planned travel route 44. to decide. As a result, when the traffic information data DTR does not represent a road section of a specific situation that is the destination of the mounted vehicle on the road along the planned travel route 44, the determination in step 51 is repeated, and the traffic information data DTR However, if it represents a road section of a specific situation that is the destination of the mounted vehicle on the road along the planned travel route 44, the routine proceeds to step 52.

  In step 52, the traffic information data DTR is supplied to the display data forming unit 18, whereby the display data forming unit 18 sets the set route data DCS from the travel route setting unit 17 and the traffic from the operation control unit 30. Based on the information data DTR, a portion corresponding to the road section in the specific situation represented by the traffic information data DTR in the planned travel route represented by the set route data DCS is displayed according to the specific situation. The image display data DSP for achieving the above is obtained. As a result, in the liquid crystal image display panel unit 22 in the image display unit 21, for example, as shown in FIG. 4, the planned travel route 44 displayed as an image is a portion 45 corresponding to a road section in a specific situation. In FIG. 5, for example, a display according to a specific situation, which is displayed with a thick line, is performed.

  Next, in step 53, it is determined whether or not the operation output data DTU from the touch operation panel unit 23 has arrived. As a result, when the operation output data DTU from the touch operation panel unit 23 has not arrived, in step 54, the mounted vehicle is in a specific situation based on the map data DM, the current position data DP, and the traffic information data DTR. It is determined whether or not the road section at is reached. As a result, when the mounted vehicle has not reached the road section in the specific situation, the process returns to step 53, and when the mounted vehicle has reached the road section in the specific situation, the process returns to step 51.

  If the operation output data DTU from the contact operation panel unit 23 has arrived as a result of the determination in step 53, the process proceeds to step 55. In step 55, an image is displayed on the planned travel route formed by the route setting data generating means, which is already set by the travel route setting unit 17 and represented by the set route data DCS, that is, on the liquid crystal image display panel unit 22. For example, a portion of the scheduled travel route 44 from the start of the portion 45 corresponding to the road section in the specific situation to a point 46 on the planned travel route 44 other than that portion, that is, a finger on the touch operation panel unit 23 The portion of the scheduled travel route 44 corresponding to the region from the start end of the portion traced by the tip end portion to the point touched by the tip end portion of the finger is not included by replacing it with another route. New route setting data to replace the part corresponding to the road section in the situation by replacing it with another route The RD is supplied to the travel route setting unit 17 together with the operation control signal CRS, and the travel route setting unit 17 is configured to change the planned travel route that is newly set according to the newly formed route setting data DRD. The resetting of the scheduled travel route is performed, and then the process returns to step 51.

  Thereby, the travel route setting unit 17 determines a portion from the start end of the portion 45 corresponding to the road section in a specific situation in the planned travel route 44 before the change to the point 46 on the planned travel route 44 other than that portion. By not replacing and including other routes, a new scheduled travel route is set in which a portion corresponding to a road section in a specific situation is replaced with another route and is not included. Then, the travel route setting unit 17 sends set route data DCS representing a new planned travel route, and supplies it to the display data forming unit 18, the audio data forming unit 19, and the operation control unit 30, and as a result, In the liquid crystal image display panel unit 22 in the image display unit 21, for example, as shown in FIG. 5, an image of a new planned travel route 44 ′ is displayed superimposed on the image of the road map 41.
