AN ASSESSMENT OF VEHICLE HANDLING TEST METHODS AND THE APPLICATION OF COMPUTER SIMULATION

Vehicle handling test techniques are discussed with reference to their usefulness in measuring responses which define vehicle behaviour desirable for safe control by A driver. Special emphasis is given to the American esv test proposals. An assessment is made of the application of current simulation techniques. Purely digital methods are identified as the most popular. A comparison between a large and complex simulation (calspan corporation) and A relatively simple one (sas) is used to demonstrate the significance of the variously available modelling techniques and possible model features. This is followed by a detailed description of the sas program and the manner in which it is used to simulate the esv tests. Experimental esv results obtained from a series of tests carried out at the TRRL test track with an Austin 1800 are reported. The results include an assessment of test repeatability and the effect of carrying out tests in opposing directions of turn. Using the sas program, various input data configurations are simulated and the effects on the esv performance of a vehicle are investigated. This allows an insight into the importance of specific simulation features and complements the previous assessment of simulation techniques. Finally, with input data for the 1800 as measured in the sas laboratories, results from the program are compared with the experimental esv results.(a) /TRRL/
