FRONT BRAKE INTERACTIONS WITH HEAVY VEHICLE STEERING AND HANDLING DURING BRAKING

To investigate certain quantifiable characteristics of handling performance, the HSRI Directional Response Computer Program for predicting the longitudinal and directional response behavior of trucks was modified to include the effects of a compliant steering system subject to the force and moment inputs of the front tires. Studies utilizing the modified program indicate that (a) no vehicle will stop perfectly straight without driver steering corrections because of steer angle deviations and (b) the steering reactions fed back to the steering wheel during braking may reverse direction with antilock brake cycling, largely because of the reversal of tire aligning torques. /GMRL/
