Abstract

A base station is installed in a driver'"'"'s house or the like where the precise position has been measured beforehand, comprises a GPS antenna, GPS receiver, and wireless communication device, and functions to transmit various data to a vehicle serving as a moving station in a predetermined range centered on the wireless communication device. The vehicle has a GPS antenna, GPS receiver, and wireless communication device. When establishing communication between base station and moving station, if the current vehicle position generally matches any driving route created and stored in the storage means earlier, automatic driving control is performed with the matching driving route serving as a target driving route. Conversely, if the current position of the vehicle matches no position on the driving routes created in the past even generally, the storage means continuously store the current driving route including the current position, as a new route to the destination.

Claims

1. A driving control device for a vehicle comprising:

a base station which has been set to a position that has been measured beforehand, for transmitting correction information to each point within a predetermined area based upon the information received from satellites orbiting the Earth;

a moving station included in said vehicle for calculating the position of the vehicle based upon the information received from said base station and the information received from said satellites;

driving-route storage means for storing the driving route along which said vehicle has moved; and

control means wherein at the time of establishment of communication between said base station and said moving station, in the event that determination is made that the current position of said vehicle calculated by said moving station has been judged as generally match with any driving route which has been stored in said driving-route storage means in the past, said control means set the target driving route to said driving route stored in the past, and perform automatic driving control of said vehicle such that said vehicle reaches the destination according to said target driving route thus set, and on the other hand, in the event that determination is made that the current position of said vehicle calculated by said moving station has been judged as different from any driving routes which have been stored in said driving-route storage means in the past, said control means continuously store the driving route including the current position, along which said vehicle is moving, in said driving-route storage means.

3. The driving control device for the vehicle according to claim 1, wherein at least one of said base station and said moving station includes said driving-route storage means.

5. The driving control device for the vehicle according to claim 1, further comprising obstacle detecting means for detecting an obstacle ahead of said vehicle along the driving route, wherein in the event that said obstacle detecting means detect the obstacle, said automatic driving control is canceled.

7. The driving control device for the vehicle according to claim 3, further comprising obstacle detecting means for detecting the obstacle ahead of said vehicle along the driving route, wherein in the event that said obstacle detecting means detect the obstacle, said automatic driving control is canceled.

9. The driving control device for the vehicle according to claim 1, wherein information transmitted from said base station includes other information as well as said correction information.

11. The driving control device for the vehicle according to claim 3, wherein information transmitted from said base station includes other information as well as said correction information.

13. The driving control device for the vehicle according to claim 5, wherein information transmitted from said base station includes other information as well as said correction information.

15. The driving control device for the vehicle according to claim 7, wherein information transmitted from said base station includes other information as well as said correction information.

2. A driving control device for a vehicle comprising:

a base station which has been set to a position that has been measured beforehand, for transmitting correction information to each point within a predetermined area based upon the information received from satellites orbiting the Earth;

a moving station included in said vehicle for calculating the position of the vehicle based upon the information received from said base station and the information received from said satellites;

driving-route storage means for storing the driving route along which said vehicle has moved; and

control means wherein at the time of establishment of communication between said base station and said moving station, in the event that determination is made that the current position of said vehicle calculated by said moving station has judged as generally match with any driving route which has been stored in said driving-route storage means in the past, said control means set the target driving route to said driving route stored in the past, and perform automatic driving control of said vehicle such that said vehicle reaches the destination according to said target driving route thus set.

4. The driving control device for the vehicle according to claim 2, wherein at least one of said base station and said moving station includes said driving-route storage means.

6. The driving control device for the vehicle according to claim 2, further comprising obstacle detecting means for detecting the obstacle ahead of said vehicle along the driving route, wherein in the event that said obstacle detecting means detect the obstacle, said automatic driving control is canceled.

8. The driving control device for the vehicle according to claim 4, further comprising obstacle detecting means for detecting the obstacle ahead of said vehicle along the driving route, wherein in the event that said obstacle detecting means detect the obstacle, said automatic driving control is canceled.

10. The driving control device for the vehicle according to claim 2, wherein information transmitted from said base station includes other information as well as said correction information.

12. The driving control device for the vehicle according to claim 4, wherein information transmitted from said base station includes other information as well as said correction information.

14. The driving control device for the vehicle according to claim 6, wherein information transmitted from said base station includes other information as well as said correction information.

16. The driving control device for the vehicle according to claim 8, wherein information transmitted from said base station includes other information as well as said correction information.
