In evaluating the brake feeling of passenger cars, it is known that vehicle postures such as pitching and heave influence other than the relationship between pedal depression force and stroke and deceleration. In this study, we focused on the transitional posture change during braking and conducted an experiment using an active suspension vehicle. As a result of sensory evaluation, it was found that even if the brake performance was not changed at all, it was confirmed that the brake feeling changed only by the difference in the transient posture, and it was not always good to suppress the vibration. In addition, we devised a method to realize the vehicle posture that was highly evaluated in the experiment by transient control of the longitudinal force distribution of the brake, and confirmed the effect in the actual vehicle.
