Japan Automobile Research Institute, Inc. (JARI) carried out three types of tests on the Minicars RSV's (hereafter referred to as M-RSV's) from April 1980 to July 1980, according to the “Memorandum of Agreements Concerning Test Program for Research Safety Vehicles” that had been concluded between the Department of Transportation (DOT) of the US government and the Ministry of International Trade and Industry (MITI) of the Japanese government. Collision Tests-The tests included a frontal collision test of a M-RSV against a fixed flat barrier, three side collision tests between each M-RSV and J-Car while both vehicles were running and a baseline side collision test between Japanese passenger cars while both vehicles were running. Handling, Stability and Braking Performance Tests-Tests were carried out on nine items for the handling and stability, and on three items for the braking performance of the M-RSV's. Visibility Tests-The field of direct view tests, the field of view tests and lighting equipment tests were carried out for the M-RSV's. The foregoing three types of tests will be discussed in this report.
