If there is a waiting time in step 13 (step 13: YES), the process proceeds to step 14.

In step 14, the charging time is calculated in consideration of the power consumption of the battery unit during the waiting time. Next, in step 15, the travel time (T1) based on the travel distance from the current position of the own vehicle calculated by the first distance calculation unit 23 to each charging facility, and similarly, the first distance calculation unit 23. The traveling time (T3) is calculated based on the traveling distance from each of the above charging facilities to the destination calculated by. Further, the charging time calculation unit 27 calculates the charging time (T4) based on each traveling route (including the presence or absence of waiting time) or the traveling distance of each candidate. Next, the control unit 10 totals the above T1 to T4 as the scheduled elapsed time (total time) from the current location D1 to the destination arrival for both travel routes R2 and R3, and selects the travel route with the shortest time. Then, it is decided as a traveling route to be traveled from now on. As a result, the charging facility S2 is determined as the route location.

Next, in step 16, the control unit 10 sets and registers the input destination D2, the determined stopover (charging facility) S2, and the determined travel route R2 in the route determination unit 17. In step 17, the notification units 18 and 19 notify the charging time (T4) and the total time. In particular, in the display unit 19, the travel route R2 from the current location to the destination via the transit point (including the set charging facility), the traveling time (T1 and T3), the waiting time (T2), and the charging facility. The charging time (T4) and the elapsed time (total time) when traveling on the entire route are displayed. Then, in step 18, the own vehicle can travel. These steps 1 to 18 are automatically performed by the control unit 10.

Further, in step 11, when there is only one travel route candidate (step 11: NO), the travel route is determined, and after that, the process proceeds to step 21, the travel time is calculated, and the travel time is calculated in step 22. Transition. If there is no waiting time in step 22 (step 22: NO), the process proceeds to step 27, and the charging time is calculated without considering the power consumption of the battery unit during the waiting time.

If there is a waiting time in step 22 (step 22: YES), the process proceeds to step 23. In step 23, the same operation as in step 14 is executed. Further, the operation from step 24 to step 26 is the same as the operation from step 16 to step 18, so the description thereof will be omitted. The control unit 10 automatically performs the operations from step 1 to step 26.

Next, when the own vehicle A starts traveling toward the destination D2 via the waypoint S2 and then shifts from step 18 to step 28 and from step 26 to step 28 (see FIG. 5), in step 28, After the own vehicle A has traveled manually or automatically, the position detection unit 22 determines whether or not the vehicle A has arrived at the charging facility S2.

Further, in a predetermined distance range from the charging facility S2 before the own vehicle A arrives at the charging facility S2, the traffic information acquisition unit 29 has acquired the traffic congestion information regarding the traveling route R2 during the traveling so far after the departure. Whether or not it is determined by the control unit 10 (step 29). Here, as the traffic jam information, with reference to FIG. 7, a traffic jam area J generated so as to cover a part of the traveling route R2 is shown.

If it is determined that the control unit 10 has acquired the congestion information (step 29: YES), in step 30, the route generation unit 16 avoids the congestion area J and reaches the destination in the shortest time. The route R4 is determined (see FIG. 7).

Next, in step 31, the traveling time of the traveling route R4 is calculated. Next, in step 32, the charging time calculation unit 17 calculates a new charging time (T4) in the traveling path R4 (see FIG. 8). Next, in step 33, the notification unit (in-vehicle speaker unit 18, display unit 19) notifies the charging time. Specifically, the display unit 19 displays a new travel path R4, a new charging time (T4), a traveling time to the destination (T3), and an elapsed time to the destination including the new charging time on the screen. (Total time) and the like are displayed on the display unit 19 and announced by the in-vehicle speaker unit 18. Therefore, this notification is performed while the vehicle A is traveling before reaching the charging facility (waypoint) S2 or during charging of the battery unit of the vehicle after reaching the charging facility (waypoint) S2. Therefore, after reaching the charging facility S2, the driver can determine and set the charging time in consideration of the minimum charging time. Further, even when a traffic jam occurs in the traveling route R2 and a new traveling route R4 is set after charging is started in the charging facility S2, the additional charging time can be set.

Here, when charging of the battery unit 15 of the own vehicle is started at the charging facility S2 and the traffic information acquisition unit 29 acquires the traffic congestion information on the traveling route R2 during charging, the direction instruction of the own vehicle is instructed. It is also possible to indicate to the driver outside the vehicle that the charging time needs to be extended by blinking the light emitting portion of the device, the brake lamp, or the like (not shown).

When the control unit 10 detects that the set charging time has elapsed in step 34, the operation is started from the charging facility R2 along the new path R4 in step 35. If the traffic information acquisition unit 29 does not acquire the traffic congestion information within a predetermined distance range until it arrives at the charging facility S2 in step 29 (step 29: NO), the process proceeds to step 36 and the vehicle is own. The charging time calculated before the start of running is set, and the progress is waited for. If the traffic jam information is acquired during the charging time of the own vehicle, the process proceeds to step 30 and the vehicle can travel along the travel route R4. From step 28 to step 35 (including step 36), the control unit 10 automatically operates.

The present invention has high industrial applicability for the technology for safely and reliably reaching a destination for a manually driven vehicle or a vehicle having an automatic driving function.
