Leyland Vehicles' recently completed Technical Centre contains a distributed network of computers and microprocessors used for engineering development testing. This paper describes an application of microprocessor technology to a programmable 'on vehicle recorder' developed for long-term data collection on commercial vehicles undergoing endurance tests. A conventional approach to data logging is to record 'raw data' over a relatively long and continuous period, with analysis carried out later on a main frame computer. As this paper will demonstrate, an alternative approach is to carry out 'real time' analysis on 'raw data' and hence be selective in what data is stored. A microprocessor forms an integral part of the 'on vehicle package'. LSI Technology reduces hardware size, weight and cost. The software is structured to perform both primary control functions and data analysis as defined by the application. An application will be discussed with reference to endurance testing and data collection on a light weight truck, relating to brake usage investigations.
