Abstract

The present invention is an information providing device which includes a vehicle side terminal, a communication center device that searches for a basic route by communication with the vehicle side terminal, and an information providing unit that provides information on the basic route to a driver, the communication center device includes a travel direction change point determination unit that determines a travel direction change point at which the vehicle changes a travel direction in the basic route, and a deviation route search unit that searches for a deviation route, based on the travel direction change point, and the information providing unit provides information on the deviation route to the driver in a case where the vehicle travels along the deviation route.

Claims

1. An information providing device which includes a mobile object terminal installed in a mobile object, a communication center device that searches for a basic route from a current position of the mobile object to a destination by communication with the mobile object terminal, and an information providing unit that provides information on the basic route to a driver of the mobile object,

wherein the communication center device includes

a travel direction change point determination unit that determines a travel direction change point at which a travel direction of the mobile object changes from the basic route, and

a deviation route search unit that searches for a deviation route that is set assuming a case where the mobile object deviates from the basic route, based on the travel direction change point, and

wherein the information providing unit provides information on the deviation route to the driver, in a case where the mobile object travels along the deviation route.

2. The information providing device according to claim 1,

wherein the deviation route search unit searches for as a deviation route, at least any one of a straight on deviation route that is set assuming a case where the mobile object travels straight on at the travel direction change point and a previous deviation route that is set assuming a case where the mobile object deviates from the basic route at the immediately previous intersection or fork to the travel direction change point.

3. The information providing device according to claim 1,

wherein the mobile object terminal has a terminal side search unit that searches for a route from a current position of the mobile object to the destination, in a case where the mobile object deviates from any one of the basic route and the deviation route, and

wherein in a case where the terminal side search unit searches for a route, the information providing unit provides information on the route to the driver.

4. The information providing device according to claim 3,

wherein the communication center device re-searches for a basic route from the current position of the mobile object to the destination by communication with the mobile object terminal, in a case where the mobile object deviates from any one of the basic route and the deviation route, and

wherein in a case where the communication center device completes re-searching, in a route that the terminal side search unit searches for, the information providing unit replaces a part that is different from the basic route that the communication center device re-searches for with the basic route, and provides information on a replaced route to the driver.

5. The information providing device according to claim 4,

wherein in the case where the communication center device completes re-searching, in the route that the terminal side search unit searches for, the information providing unit replaces a part that is not yet information provided and different from the basic route that the communication center device re-searches for with the basic route, and provides information on a replaced route to the driver.

6. The information providing device according to claim 1,

wherein the information providing unit includes a display that provides information to an occupant of the mobile object.

7. The information providing device according to claims 2,

wherein the information providing unit includes a display that provides information to an occupant of the mobile object.

8. The information providing device according to claims 3,

wherein the information providing unit includes a display that provides information to an occupant of the mobile object.

9. The information providing device according to claims 4,

wherein the information providing unit includes a display that provides information to an occupant of the mobile object.

10. The information providing device according to claims 5,

wherein the information providing unit includes a display that provides information to an occupant of the mobile object.

11. The information providing device according to claim 2,

wherein the mobile object terminal has a terminal side search unit that searches for a route from a current position of the mobile object to the destination, in a case where the mobile object deviates from any one of the basic route and the deviation route, and

wherein in a case where the terminal side search unit searches for a route, the information providing unit provides information on the route to the driver.
