As the complexity of the motor vehicle and the amount of its associated legislation has increased, the quantity of test and development data required from a vehicle, together with the speed of collection has increased to such an extent that it is no longer practical to employ traditional analogue techniques for the measurement of vehicle parameters. This paper discusses the advantages of data logging and the 'clean sheet' approach to the specification of the in-vehicle Data Logging System, its philosophy and subsequent development. The reasons for the choice of a proprietory logger with software modifications, mass storage medium, graphics package and the desk-top computer used for analysis, are discussed together with the means of coping with extremes of ambient operating temperaures.
