First, for evaluating vehicle emergency handling performance in real world, several course patterns of closed-loop test (task performance test) similar to occurring patterns of real accidents were set, and vehicles maximum entering velocity of each course was measured. Second, the velocity was normalised by each vehicle's basic dimensions (mass, height of center of gravity, tread etc.), to enable the comparison of tire and suspension performance. Finally an estimation method of the results of the closed-loop tests was produced, using a vehicle's design parameters, which include basic dimensions, suspension and tire. It is considered that this estimation method can reduce the time for developing cars. For the covering abstract see ITRD E825082.
