Abstract
A motor-vehicle navigation-based speed limit recording and warning system designed to automatically inform drivers when they are exceeding the posted speed limit on a particular roadway. The system includes a navigational system that displays a plurality of roadways on a map and the motor vehicle'"'"'s location thereon. The navigational system also includes a “mark” point feature or function that enables a driver to manually enter “mark” points and assign a speed limit to each “mark” point. The “mark” point feature or function may be directly coupled to the motor vehicle'"'"'s speedometer so that the driver may simultaneously input both the motor vehicle'"'"'s current speed and the “mark” point on the roadway. Later when traveling on the same roadway, the relative locations of the “mark” points along with their assigned speed limits, and the current location and speed of the motor vehicle are displayed to the driver to inform him or her of the most recently passed posted speed limit and when the posted speed limit is exceeded.
