1. A system for monitoring the performance and movements of a motor vehicle comprising:

  • a sensing module for sensing the vehicle'"'"'s instantaneous acceleration in at least two directions and generating coded signals in accordance therewith;

    a computer for computing performance variables of the vehicle from the coded signals generated by the sensing module and storing coded representations of said performance variables in select locations of a memory along with associated time and date codes;

    a short wave transmitter/receiver interfaced to said computer for transmitting and receiving radio signals to and from a remote monitor station;

    wherein said computer is programmed to control the transmission to a remote monitor station of radio signals modulated with digital information corresponding to the stored performance variables;

    a receiver interfaced to said computer for receiving signals from a satellite global positioning system, wherein said computer is programmed to calculate the global position of the vehicle from the satellite signals and store a coded representation of same in a select memory location;

    wherein said computer is programmed to analyze the stored performance variables over a period of time, compute an evaluation code corresponding to an assessment as to how the vehicle is being driven, store said evaluation code in a select location in memory, and to warn a driver of the vehicle when an evaluation code is computed which corresponds to an hazardous driving pattern; and

    controllers for controlling the speed of the vehicle, said controllers being activated in response to the detection of a hazardous driving pattern.
