Abstract
A vehicle speed detecting device utilizes two vehicle speed pulse generators, a vehicle speed memory device, pulse counters, abnormality detectors, pulse signal transfer devices and an alarm device which are all integrated into the electronic control circuit of a micro-processor through two sets of signal processing devices. The detecting device not only indicates the speed of the vehicle but also detects abnormalities in either of the vehicle speed pulse generators and provides an appropriate alarm.
