Microprocessors in an automotive application

Recent developments in microelectronic technology, particularly the microprocessor, have resulted in interesting developments for automatic control of transport machines, such as locomotives and aircraft. The paper considers the convenience of this technology in a `domestic¿¿ application: the control, indirectly, of the distance between vehicles in foggy weather and dark, obscured conditions. An easily available Doppler radar module and ultrasonic transducers are used jointly as remote sensors.
