Vehicle speed monitoring system and method
First Claim
1. A device for monitoring the speed of a vehicle driven by a driver in relation to a posted speed limit, said device comprising:
- (a) a GPS receiver for determining the location and speed of the vehicle;
(b) an input device adapted to allow the driver to input a speed tolerance profile which includes a driver selected tolerance range for the posted speed limit;
(c) a memory coupled to said GPS receiver and said input device for storing said speed tolerance profile;
(d) a processor coupled to said GPS receiver, said input device, and said memory, for determining the posted speed limit, for comparing the speed of the vehicle with the posted speed limit, calculating the difference in speed between the speed of the vehicle and the posted speed limit, and generating a warning when said difference in speed exceeds the driver selected tolerance range for the posted speed limit.

Abstract
The present invention comprises a vehicle speed monitoring device which enables a driver to enter a speed tolerance profile that represents the driver'"'"'s personal travel speed preferences and which alerts the driver when the vehicle speed falls outside the speed tolerance profile. Specifically, the speed tolerance profile consists of a number of speed tolerance ranges, each associated with a particular posted speed limit. As the vehicle travels through various map zones, the applicable posted speed limit is determined using a customized GPS map. The device determines the vehicle location, speed and the posted speed limit and then compares the vehicle speed using a running average to see whether vehicle speed is within the driver'"'"'s speed tolerance profile and if not, the device provides the driver with a visual and/or audible warning according to the driver'"'"'s operational preferences.
