Maneuverability evaluation method of the vehicle and maneuverability evaluation method null

摘要

PPROBLEM TO BE SOLVED: To enable an easy test, when evaluating movement performance of vehicles, and to provide evaluation methods for the movement performance of the vehicle and tire, capable of obtaining precise evaluation result on the movement performance of the vehicle, using the measurement result in this test. PSOLUTION: The evaluation method for the movement performance of vehicle calculates the frequency transfer function of the predetermined physical quantity of the vehicle, by providing random steering inputs to the vehicle; it calculates the time series response data of the physical quantity, by using the frequency transfer function and time series response data of desired steering angles; at this time, it evaluates the movement performance of the vehicle from this time series response data. The evaluation method for the movement performance of tires evaluates the movement performance of the vehicle with the method, by using the time series response data of the same steering angles each time, when mounting different testing tires to the vehicle; and it conducts relative evaluation of this evaluation result as the movement performance of the testing tires, among a plurality of the testing tires.
