Patent ID: 7362239

Claim:
A vehicle warning system responsive to speed and position of the vehicle, the system comprising: an antenna subsystem arranged for capturing location based information system signals; a radio frequency processing subsystem which is arranged to receive the signals from the antenna subsystem to determine a current position and a current velocity of the motor vehicle; a local data storage including location alert points and road segment representations with speed data associated therewith, the location alert points each being representative of a given location, and the road segment representations with speed data associated therewith each being representative of an actual road segment and a speed limit for the actual road segment; a processor which is arranged to compare the current position and the current velocity determined by the radio frequency processing subsystem to the local data storage to determine an alarm condition if the current position approaches a location alert point or if the current position corresponds with one of the road segment representations and the current velocity exceeds the speed data associated therewith; an indicator arranged to alert an operator of the motor vehicle of the alarm condition; a power supply arranged for supplying electrical power to the system; the power supply being arranged to be disconnected such that the system is automatically powered down under software control in response to the current position remaining unchanged for an elapsed period of time; a communication processing subsystem arranged for connecting the local storage data to a remote server to update the local data storage.
