A digital computerized energy distribution and automated control system is being developed at Essex International's Vehicular Research and MOS Manufacturing Facilities in Pittsburgh. The control system is comprised of a central computer in conjunction with a digital multiplexing system. Prototypes of the system have been tested; the subsystems of the car that were tested include fuel injection, ignition, power assist, comfort, and lighting.In its final form this system will make decisions for all the subsystems on the automobile. For example, antiskid braking, gear selection, automatic speed control, and driver displays will be incorporated. The system will evolve onto the car in pieces such as engine control, lighting, and automatic temperature control. Then, as economic factors dictate, the components will evolve into a single computerized system. The automatic temperature control system is economical today. The central computer will be economical for certain functions in 2-3 years.
