Patent ID: 7937997

Claim:
A tire braking characteristic test apparatus, comprising: a substitute road surface body; a pair of tires capable of rolling on a virtual road surface formed by said substitute road surface body; braking force impartation means capable of imparting braking force to at least one of said tires; angle control means for controlling a sideslip angle of the at least one of said tires; ground height control means capable of controlling ground height of said tires; ground load measurement means capable of measuring ground loads of said tires; front-rear force measurement means capable of measuring front-rear force of said tires; speed control means capable of controlling speed of said substitute road surface body; and processing/controlling means provided with a two-dimensional vehicle model adapted to be inputted actual measurement values of the ground loads and the front-rear force of said tires obtained from said ground load measurement means and said front-rear force measurement means, for performing a calculation processing with regard to a motion of the vehicle model on the basis of the actual measurement values, and outputting command values on the basis of the calculation processing to said ground height control means and said speed control means to control a rolling state of a pair of said tires.
