Abstract: An electronic automotive speed control safety device, which limits the maximum speed (Top Speed) allowed of any vehicle, in real time, based on the road it is traveling on. Combining the current GPS navigation technology and the electronic speed limiter technology, this device monitors and controls the maximum speed allowed of the vehicle for particular road it is travelling on. This device recognize the location of the vehicle, current speed, posted speed limit, and limits the maximum speed of the vehicle for that location. The maximum speed limit allowed is programmed by software setting during the time of installation. For example, if you want to allow your 16 year old child to be able to drive up to 30 MPH on the 25 MPH Zone, you can program the OVER_SPEED_LIMIT (OSL) parameter to +5.
