<p>The present invention is to provide a tire braking characteristic test apparatus capable of reflecting dynamic characteristic of a vehicle at the time of braking in order to evaluate braking characteristic of tires and also performing a test with easily changing a vehicle condition influencing the braking characteristic of the tires. The present invention is provided with a pair of tires T capable of rolling on a substitute road surface body 9, braking force impartation means 19 capable of imparting the braking force on the tires T, ground height control means 16 for measuring and controlling ground height of the tires T, ground load measurement means 17 for measuring ground loads of the tires T, front-rear force measurement means 18 for measuring front-rear force of the tires T, speed control means 13 for controlling speed of the substitute road surface body 9, and a two-dimensional vehicle model M adapted to be inputted actual measurement values of the ground loads and the front-rear force of the tires T obtained from the above means, and also provided with processing/controlling means 3 for outputting command values on the basis of a calculation processing of the vehicle model M with regard to a motion to the above means and controlling a rolling state of a pair of tires T.</p> |
