    摘要: An antilock brake system with separate front- and rear-wheel safety means, in which front-wheel antilock control means and rear-wheel antilock control means are made so operative independently of each other that, when the front-wheel antilock control means for a front wheel generally having a larger proportion of the brake force distributed is troubled in its brake force suppressing state, front-wheel saftey means makes the function of the front-wheel antilock control means wholly ineffective to ensure the brake force to the front wheel whereas, when the rear-wheel antilock control means for a rear wheel generally having a smaller proportion of the brake force distributed is troubled in a state having lost its brake force suppressing function, rear-wheel safety means operates to effect that the brake force to the rear wheel is always stronger than that to the front-wheel thereby to maintain the steering stability of the wheeled vehicle.

    摘要: A control circuit for a vehicle leveling system which operates to restore the vehicle height to be within a reference vehicle height range. The control circuit comprises a first detecting device which detects the direction of change in the vehicle height, a second detecting device which determines the necessity of levelling operation, a logic circuit which properly controls the leveling operation in response to outputs of the first and second detecting devices, and a holding circuit which increases the duration of an OFF signal so as to render the pneumatic system of the vehicle to be inoperative, for a predetermined length of time. The control circuit effects adjustment in height in response to those changes in vehicle height which inherently require adjustment and avoids any adjustment in response to those changes in vehicle height which naturally occur instantaneously under normal driving conditions.

    摘要: A method of preventing wheels of a vehicle from skidding, including the steps of detecting the peripheral speed of a wheel and picking it up as a wheel-speed signal, detecting the vehicle speed and setting a reference wheel-speed signal based on the detected vehicle speed, deriving a wheel-acceleration signal from said wheel-speed signal, and setting a reference wheel-deceleration signal for comparison with said wheel-acceleration signal. During braking operation, the brake torque applied to the wheel is controlled such that it is maintained constant to prevent the further increase thereof when the level of the wheel-accleration signal decreases below the level of said wheel-deceleration signal under the condition that the level of said wheel-speed signal is higher than that of said reference wheel-speed signal. On the other hand, if the level of said wheel-speed signal is lower than that of said reference wheel-speed signal, the brake torque is reduced when the level of said wheel-acceleration signal decreases below the level of said reference wheel-deceleration signal. Preferably, in order to make much finer and more accurate control over the brake torque, various reference signals are set for comparison with said vehicle-speed signal, said wheel speed signal and said wheel-acceleration signal, and logical judgements are made on the respective signals. In addition, peripheral speeds of a plurality of wheels are preferably detected and the greatest peripheral speed thereof is used for estimation of said vehicle speed.

    摘要: An antiskid brake controlling method and apparatus comprising: comparing by a first comparator and during braking of a vehicle, a wheel speed signal V.sub.w representative of the peripheral speed of a wheel of the vehicle with a first reference wheel speed signal V.sub.R 1 less than a vehicle speed signal V.sub.E and with a second reference wheel speed signal V.sub.R 2 which is less than the first reference wheel speed signal V.sub.R 1; comparing by a second comparator a wheel acceleration signal V.sub.w representative of the peripheral acceleration of the wheel with a first reference wheel acceleration signal V.sub.wl representing a predetermined positive peripheral acceleration of the wheel, a second reference wheel acceleration signal V.sub.w2 greater than the first reference wheel acceleration signal and a reference wheel deceleration signal -V.sub.w3 representative of a predetermined negative peripheral acceleration of the wheel. The comparators are connected through an electrical circuit to solenoids of control valves which regulate flow of pressure fluid to a wheel brake cylinder for selectively counteracting the pressure of brake fluid from a master cylinder to the brake cylinder or maintaining constant pressure in the brake cylinder. The electrical circuit is operative to decrease the braking torque T.sub.B from an instant at which the wheel acceleration signal V.sub.w has dropped below the reference wheel deceleration signal -V.sub.w3 when the wheel speed signal V.sub.w is less than the first reference wheel speed signal V.sub.R 1 but greater than the second reference wheel speed signal V.sub.R 2; to stop the decrease of the braking torque T.sub.B after the wheel acceleration signal V.sub.w comes to increase again, at an instant at which the wheel acceleration signal V.sub.w exceeds the reference wheel deceleration signal -V.sub.w3 ; and also to decrease the braking torque T.sub.B until the wheel acceleration signal V.sub.w increases to exceed the first reference wheel acceleration signal V.sub.wl when the wheel speed signal V.sub.w has dropped below the second reference wheel speed signal V.sub.R 2.
