PROBLEM TO BE SOLVED: To verify vehicle body deceleration degree when performing braking with an accuracy close to a verifying test by an actual vehicle. SOLUTION: In a brake device model, coefficient of friction data of a brake friction material, piston diameter data of a caliper piston and a wheel cylinder, effective diameter data of a brake disc and a brake drum, and coefficient of friction characteristic data of the brake friction material are defined in advance. The coefficient of friction characteristic data of the brake friction material is defined by using two-dimensional matrix data of wheel speed and a coefficient of friction characteristic set for speed when performing braking.
