Abstract

This invention is a means for detecting and logging the number of instances that predetermined speeds have been exceeded. This device can be used by car owners to monitor their driving habits as well as those of others using the car. Also the device of the present invention can be used by insurance companies in determining insurance rates based on driving performance.

Claims

1. An apparatus for monitoring the speed of a vehicle comprising:

(a) data storage means operatively mounted in said vehicle for storing a plurality of predetermined speed levels, said data storage means including means for representing said speed levels as electrical signals;

(b) means for sensing the speed of said vehicle and converting the same to an electrical signal indicative of the speed of said vehicle;

(c) signal processing means for continuously comparing the speed of said vehicle with each of said speed levels during the operation of said vehicle to determine each occurance in which a vehicle accelerates beyond each particular speed level;

(d) a number of separate registers equal to the number of preset speed levels so that every register is independently paired with a single speed level, each register incremented by said signal processing means when vehicle speed accelerates past the speed level paired with that register, so that said registers store the number of times the vehicle accelerates past each speed level; and

(e) means for retrieving such stored information from said registers whereby the cumulative incremental speed performance of said vehicle can be determined.

2. The apparatus of claim 1 wherein said means for comparing the speed of said vehicle to said predetermined speed levels includes a micro-computer.

3. The apparatus of claim 2 wherein said sensing means is a magnetic pickup securable to a driveshaft of a vehicle and operatively connected to said micro-computer.

4. The apparatus of claim 1 wherein said retrieving means includes display means connected to said counting means for displaying the number of times each speed level is exceeded.

5. The apparatus of claim 1 wherein said retrieving means includes an alphanumeric printer for printing the number of times each speed level is exceeded.
