ABSTRACT:
A vehicle speed alarm is used to alert a driver of a vehicle that the instantaneous speed thereof has exceeded a pre-established maximum vehicular speed. The speed alarm produces a reference signal upon receipt of a transmitted signal containing information corresponding to the pre-established maximum vehicle speed. This reference signal is compared with a speed signal which corresponds to the instantaneous speed of the vehicle. When the instantaneous speed of the vehicle exceeds the pre-established maximum speed, a control signal is developed to alert the driver of that condition.
