Abstract

An automobile communication system which provides for transmitting stations located along highways and facilities located in vehicles such that the vehicle can receive information as to stop signs, whether the vehicle should turn left or right or proceed straight forward, distances to particular landmarks on the highway are given. Signal lights may be indicated in the vehicle as well as the speed of the vehicle. A driver instructed memory in the vehicle can be supplied with information indicating which particular highway the vehicle intends and desires to travel as well as other parameters.

Claims

1. A ground vehicle system comprising, a plurality of fixed transmitters installed at different locations along a highway, modulator means connected to each of said fixed transmitters, memory means connected to each of said modulator means to supply highway intelligence, a receiver mounted on a vehicle and tuned to receive information from said fixed transmitters, a data processor connected to said receiver, a vehicle memory connected to said data processor, utilization means connected to said data processor to utilize selected information transmitted by said fixed transmitters, and wherein said vehicle memory selects information from the received information relevant to stop signs.

2. A ground vehicle system according to claim 1 wherein said vehicle memory selects information from the received information relevant to one of a plurality of highways.

3. A ground vehicle system according to claim 1 wherein said vehicle memory selects information from the received information relevant to direction of one of a plurality of highways at an intersection.

4. A ground vehicle system according to claim 1 wherein said utilization means includes an automatic control system for said vehicle.

5. A ground vehicle system according to claim 1 wherein said vehicle memory selects information from the received information relevant to signal lights.

6. A ground vehicle system according to claim 1 wherein said vehicle memory selects information from the received information relevant to distance to go to a reference location.

7. A ground vehicle system according to claim 1 wherein said utiliZation means includes visual indicators.

8. A ground vehicle system according to claim 1 wherein said utilization means includes audible indicators.

9. A ground vehicle system comprising, a plurality of fixed transmitters installed at different locations along a highway, modulator means connected to each of said fixed transmitters, memory means connected to each of said modulator means to supply highway intelligence, a receiver mounted on a vehicle and tuned to receive information from said fixed transmitters, a data processor connected to said receiver, a vehicle memory connected to said data processor, utilization means connected to said data processor to utilize selected information transmitted by said fixed transmitters, and wherein said vehicle system includes direction determining circuitry so that the bearing between the vehicle and one of said fixed transmitters can be determined.

10. A ground vehicle system according to claim 9 wherein said vehicle system includes a time base generator connected to said processor to allow the velocity of the vehicle to be calculated.

11. A ground vehicle system comprising, a plurality of fixed transmitters installed at different locations along a highway, modulator means connected to each of said fixed transmitters, memory means connected to each of said modulator means to supply highway intelligence, a receiver mounted on a vehicle and tuned to receive information from said fixed transmitters, a data processor connected to said receiver, a vehicle memory connected to said data processor, utilization means connected to said data processor to utilize selected information transmitted by said fixed transmitters, and wherein said vehicle includes a power transmitter and said fixed transmitters include a power receiver tuned to said power transmitter for driving said fixed transmitter.
