Abstract

A base computer includes a plurality of vehicle managers that communicate via an rf link to corresponding vehicle controllers (VCON) in remotely-operated vehicles on a test track. The base computer also includes a traffic manager that communicates with the vehicle managers to effect overall control of the test facility. The vehicle managers download desired missions to their respective VCONs, and receive status reports back from their VCONs.

Claims

1. A base computer for generating signals for controlling a plurality of vehicles, each vehicle including an on-board vehicle controller (VCON) and a vehicle transceiver, the vehicles being disposed on a test track, the base computer comprising:

a communication transceiver for sending and receiving information to and from the vehicle transceivers;

for each VCON, a respective vehicle manager, each vehicle manager coupled to the communication transceiver for communication with its respective VCON for communicating mission signals thereto and for receiving status signals therefrom;

a global memory coupled for exchange of information with each vehicle manager, including the mission signals and the status signals;

a traffic manager coupled to the global memory for receiving the status signals and generating control signals in response for storage in the global memory; and

a wake-up listener coupled to the communication'"'"'s transceiver for establishing a vehicle manager when a corresponding VCON is activated.

2. The base computer of claim 1, wherein the traffic manager generates a control signal when a status signal indicates that a vehicle'"'"'s speed is less than a predetermined speed.

3. The base computer of claim 1, wherein the traffic manager generates a control signal when a status signal indicates that a vehicle'"'"'s position is outside an expected position envelope.

4. The base computer of claim 1, wherein the traffic manager generates a control signal when a status signal indicates that the distance between any two vehicles is less than a minimum separation distance.

5. The base computer of claim 1, further comprising:

a date base interface coupled for communication with each vehicle manager and with a database;

an operator computer for generating mission signals representative of desired vehicle movements around the test track and for transmitting such mission signals via the database to the database interface.

6. The base computer of claim 1, wherein the communications transceiver utilizes radio frequency (rf) communication via a base antenna electrically connected to the transceiver for sending mission and control signals and for receiving status signals.

7. The base computer of claim 6, wherein each status signal represents vehicle fuel status, vehicle position, vehicle speed, and vehicle shock absorber temperature.

8. The base computer of claim 7, in combination with:

a plurality of position transponders, each disposed at a fixed location on the track;

at least one guide wire disposed on the track; and

at least one frequency generator electrically connected to the guide wire for generating an ac signal therein, the ac signal characterized by a frequency.
