Patent ID: 8751133

Claim:
A speed limiter system for limiting the maximum speed of a vehicle, the system comprises: a user identification device for identifying the user of the vehicle; a navigation device for determining an actual position of the vehicle on a road map; a speed limit database of posted speed limits for respective segments of roads of the road map; a user database including, for each user, a respective user over-speed parameter corresponding to the respective road segment; a speed controller device including an allowed maximum speed algorithm connecting to the user identification device, the navigation device, the speed limit database and the user database, the allowed maximum speed algorithm determining in real time an actual allowed maximum speed limit by adding the actual road segment posted speed limit to the corresponding user over-speed parameter; and said speed controller device further connecting to an engine control unit, a vehicle speed source and a throttle position sensor of the vehicle, when the vehicle speed determined from the vehicle speed source is within a predetermined activation range below the actual allowed maximum speed limit, the controller device modifying an actual throttle sensor signal from the throttle position sensor to the engine control unit to prevent the user from driving the vehicle at a speed beyond the actual allowed maximum speed limit.
