Abstract: In order to improve the cornering of a vehicle under braking, control is based on the single angle and the rate at which the steering angle is changing. When the rate at which the steering angle is changing is high the braking force on the outboard side of the vehicle with respect to the direction in which it is turning, is reduced with respect to that on the inboard side while in the case that the steering angle is relatively large, the braking force on the inboard side is reduced with respect to that on the outboard side. As an alternative to brake force reduction, it is possible to increase the braking force on the side opposite to that wherein reduction would be implemented. Parameters which are used to weight the control are steering angle acceleration, which speed, and vehicle deceleration.

Abstract: A vehicle turning behavior control system is mounted in an automotive vehicle having an anti-skid braking system. The control system has an electronic control unit to which a signal representative of a vehicle turning condition is input. The control unit is arranged to establish a difference between braking forces applied respectively to inside and outside wheels (with respect to a vehicle turning direction) in accordance with the turning condition representative signal so as to develop a yaw moment between the inside and outside wheels to promote a turning of the vehicle. The control unit also functions to control the braking force applied to the outside wheel in accordance with the braking force applied to the inside wheel by the anti-skid system in a manner such that the former braking force changes in a similar pattern to the latter braking force.

Abstract: An anti-skid brake control system is capable of optimizing vehicular braking characteristics in order to minimize the braking distance. The anti-skid brake control system takes a feature of the vehicle speed dependent wheel slippage threshold. For this, the anti-skid brake control system of the invention employs a wheel slippage threshold deriving means which derives a wheel slippage threshold on the basis of a vehicle speed. The wheel slippage threshold is compared with an actual wheel slippage detected on the basis of a vehicle speed and a wheel speed. Brake pressure in a wheel cylinder is reduced when the detected wheel slippage is increased across the wheel slippage threshold.
