A relatively complex microprocessor system, the General Motors Trip Computer, is now incorporated in some production automobiles. An outline of the operation and functions provided by the microprocessor system is given. A prototype digital engine-control system that combines fuel injection and full electronic ignition, developed by Robert Bosch Gmbtt, is briefly described. Also described is an experimental automotive electronics system based on a digital information system approach. A set of sensors provides a data format to an information data bus that distributes information throughout the vehicle in a common format. An information processing system performs data processing and storage. An information presentation, control, and actuation system provides the required display and control signals. Great concern is shown over the reliability of these new complex systems. In fact, the reliability of automotive electronic systems must be an order of magnitude greater than it is today. However, burn-in testing, historically used in serving military customers, is too time consuming and costly for the automotive customer.
