Abstract

A system for monitoring the speed and location of a vehicle over a given area by using a global positioning system and comparing the position fix and speed against a computerized map for the area containing predetermined limits for the speed and territory over predetermined times and days of the week. If a limit is exceeded the position fix and speed information is stored along with the time when it took place. The stored information can be optionally transmitted to a remote location for further processing. Also, alarm circuits are provided inside the vehicle to selectively alert the occupants that a limit has been exceeded.

Claims

1. A system for monitoring the speed and location of a vehicle over a given area, comprising:

A) global positioning means for providing the position fix and speed information of a vehicle; and

B) computerized means for receiving position fix and speed data and further including storage means for storing data and software;

C) software means for mapping a predetermined area including overlay software means for coding portions of said area and said coded portions including predetermined vehicle speed limits over at least two time and date periods;

D) means for comparing said position fix and speed data with said coded portions to determine violations;

E) means for generating an output signal upon the occurrence of at least one of said violations; and

F) means for codifying said output signal in accordance with a user'"'"'s desire or level of attention and further including means for transmitting said codified signal to a remote user'"'"'s receiver as an alarm.

2. The system set forth in claim 1

wherein said receiver includes a remote computer assembly including means for receiving said position fix and speed data that caused the generation of said output signal.

3. The system set forth in claim 2 further including alarm means installed within said vehicle for selectively alerting the occupants that at least one of said violations has occurred.

4. The system set forth in claim 3 wherein said remote computer assembly is selectively programmed to activate said alarm means.
