Automobile overspeed warning system
First Claim
1. An automobile overspeed warning system for a passenger car comprising:
- a speed sensor for sensing the speed of the automobile;
a speed selector on which an operator may select a warning speed, said speed selector being mountable within reach of the driver of the car, and being operable at any time the motor of the car is running;
a warning speed display connected to show the selected warning speed, said warning speed display being mountable in a location visible to the driver of the car;
a comparator for comparing the speed sensed by said sensor with the warning speed selected with said selector;
a warning annunciator connected to said comparator to give a warning when the speed sensed exceeds the warning speed selected; and
said selector includes a knob that is(a) moveable, at any time, to an "On" position for activating said system, and to an "Off" position for de-activating said system,(b) operable in said "On" position to select the desired speed,(c) operable in said "On" position, while the car is in motion, to change the selected speed; and
(d) operable to cause the selected speed to be shown on said warning speed display.

Abstract
An automobile overspeed warning system includes speed sensors for sensing the rate at which an automobile is travelling and speed selectors for receiving an input from the automobile driver indicating a top speed which the driver seeks not to exceed. The overspeed warning system compares the two values and activates an alarm when the desired limit is exceeded. The system can be used in conjunction with an existing cruise control system as a back-up system to warn the driver that the cruise control system has not been reset, or it can be used independently of a cruise control system to prevent the driver of an automobile from unknowingly or inadvertently operating his or her vehicle in excess of a certain speed for safety or other reasons. The system can be provided as a retrofit kit or as an integral part of an existing micro-processor controlled electrical system within the automobile.
