An LCD Driver Information Center for Automotive Applications

An automotive diagnostic package has been developed which utilizes a systems approach to convey information such as lamp failures, improper fluid levels, and various other warnings as well as service reminders. It incorporates a microprocessor controlled liquid crystal display consisting of printed messages and an outline of a vehicle; thus a message will be supplemented with an indication of the problem location on the vehicle. The unit is designed for English or Metric use, allowing the miles or kilometers remaining to recommended services to be displayed upon command.
