A MICROPROCESSOR CONTROLLER FOR RESEARCH STUDIES ON AN ECONOMY TRANSMISSION
An electronically controlled five speed mechanical drive transmission was built and developed to provide fundamental engineering information on the possible strategies and fuel economy benefits of a microprocessor control system. A general purpose microprocessor was configured to provide extensive data logging and monitoring facilities as well as transmission control duties. Both hardware and software were designed for maximum flexibility of program function and operating strategies. The microprocessor program structure as described was developed directly by the automotive development engineers concerned and its progression from initial concept to fully operational state is outlined. The majority of the fuel economy evaluations were carried out over actual road routes and techniques are described for logging and presenting data to analyse the effectiveness of different control strategies. Examples of fuel economy results and associated statistical data are given.
