IDEAS FOR CAR COMPUTER-CONTROLS: AND THEIR REALISATION

To illustrate the growing importance of electronically assisted vehicle functions, the article examines equipment being developed in four main areas - control instrumentation, engine management safety (comfort and entertainment). The example described is the Compucruise trip computer developed by National Semiconductor. The unit operates on signals monitored by sensors attached to crankshaft and fuel supply line. A flow transducer in the fuel line generates pulses from which the computer can calculate fuel consumed. By suitable calibrations the system can carry out 44 separate functions which enables a driver to maintain a selected speed, and check effects of fuel grade and tyre pressures for example. It also indicates time, distance, fuel available to reach a given point based on fuel consumption, temperature, pressure and levels of engine and transmission oils, coolant and brake fluid. Other functions of engine and exhaust control are described. (TRRL)
