METHOD OF ADJUSTING STRAIGHT AHEAD TRAVELING CAPABILITY OF VEHICLE

摘要

A method of adjusting the straight ahead traveling capability of a vehicle capable of surely performing the adjusting operation for the straight ahead traveling capability of the vehicle in a short time without requiring a skilled worker, comprising the steps of putting the vehicle on the rollers of a bench tester after adjusting an alignment, reproducing the actual traveling state of the vehicle, measuring the lateral forces of wheels, determining whether or not the measured lateral forces come within a pre-set reference range, and determining whether or not the lateral forces of the wheels out of the reference range come within the reference range when a toe angle is corrected within a pre-set allowable toe angle correction range and when the lateral forces are determined to come within the reference range, correcting the toe angle within the allowable correction range, correcting the lateral forces to come within the reference range, providing the lateral forces of the wheels after correcting the toe angle, calculating the run amount of the vehicle by using the lateral forces of the wheels thus obtained, and determining by using the calculated run amount whether the straight ahead traveling capability is acceptable or not.
