Brake control system for vehicle

摘要

Disclosed is a brake control system for a motor vehicle comprising a wheel braking device (M5) for providing the brake for a wheel of the vehicle in accordance with pressure, a braking pressure adjusting device (M6) for adjusting the braking pressure applied to the wheel braking device (M5), a detector (M4) for detecting a rotational state of the wheel, a rotational state setting device (M8) for setting an optimally rotational state of the wheel in accordance with an operating condition of the vehicle, and a control unit (M9) for feedback-controlling the braking pressure adjusting device (M6) so that the detected rotational state is equal to the set rotational state.

The control unit (M9) is constructed as an integral-added optimal regulator which controls the braking pressure adjusting device (M6) on the basis of an optimal feedback gain predetermined in accordance with a dynamic model of a system relating to the brake of the vehicle.

The brake control system with such an arrangement makes possible to provide quick response and high stability on the braking operation of the vehicle.
