  • Patent number: 4991910
    Abstract: An anti-lock control system for motor vehicles is designed to have its computed vehicle speed modified as the motor vehicle is braked. In this invention, the computed vehicle speed persists along a reference deceleration gradient line representing a predetermined acceleration follow-up limit measured with respect to the wheel speed for a predetermined period of time from a point of time when the deceleration of the computed vehicle speed reaches the reference deceleration gradient line for the first time after the motor vehicle was braked. Thereafter, the computed vehicle speed is modified to follow a deceleration gradient line with a gradient that is gentler than that of the reference deceleration gradient line, until a threshold speed is reached, which is lower by a predetermined amount than and follows the computed vehicle speed with such a speed difference.

  • Patent number: 4883325
    Abstract: In an anti-lock control system for motor vehicles, the design is made such that when the motor vehicle is running on a rough road, reduction of the brake hydraulic pressure can be prevented from being started early by detecting that the motor vehicle is running on the rough road, and such that any adverse effects can be avoided which tend to be produced in the case where a device for coping with the rough road is applied when the road surface on which the motor vehicle is running is a low-.mu. road surface or when the motor vehicle is running with a low speed.

  • Patent number: 4811232
    Abstract: An apparatus for measuring the wheel speed for an anti-skid control system of a motor vehicle, comprising a sensor for generating a pulse signal, the cycle of which corresponds to the rotational speed of the wheel. The wheel speed signal is provided in every control cycle having a constant time. If the wheel speed is not provided because the rotational speed of the wheel is low, the anti-skid control is performed in accordance with a compensated wheel speed calculated on the basis of the wheel speed measured immediately beforehand.

  • Patent number: 4762375
    Abstract: An anti-skid control system for a motor vehicle in which, when a wheel speed to be controlled and being decreased through buildup of brake pressure becomes equal to a reference speed, this equality is judged as a fulfillment of a brake pressure reduction starting condition, and thus reduction of the brake pressure is started. The highest wheel speed is detected and a computed vehicle speed is set up based on the highest wheel speed by having the increase and decrease of the highest wheel speed limited to a predetermined range. The computed vehicle speed and the wheel speed to be controlled are compared; and when the comparison indicates that the wheel speed to be controlled is equal to or higher than the computed vehicle speed, no reduction of the brake pressure is started irrespective of whether the brake pressure reduction starting condition is fulfilled.
