A SIMPLIFIED, INTERACTIVE SIMULATION FOR PREDICTING THE BRAKING AND STEERING RESPONSE OF COMMERCIAL VEHICLES

An interactive computer program which predicts the response of trucks and tractor-trailers to braking and steering inputs is documented. The mathematical model simulating the vehicle and the input/output of the computer program have been designed to elicit simplicity of operation rather than extreme accuracy. Thus, quasi-static load transfer is used, and wheel spin degrees of freedom are neglected. Special features of the simulation include provisions for tandem axles with inter-axle load transfers, dual tires, brake imbalance, and the effectiveness of antilock braking systems. /Author/
