    摘要: This invention relates to a hydraulic brake system for automotive vehicle with a master cylinder (2) and with a hydraulic power booster (1) connected upstream of the master cylinder (2) and having a pressure chamber (4) in which an auxiliary pressure depending on the actuating force (F) may be modulated via a pedal-operable brake valve (7). Wheel brakes (51, 53) of a first brake circuit are connected at the pressure chamber (4), wheel brakes (50, 52) of a second brake circuit being connected at the master cylinder (2). The braking pressure active in the wheel brakes (50 through 53) is controllable by valve members (39, 54 through 59) controllable in dependence on the slip. In case of control, a hydraulic communication will be established between the pressure chamber (4) of a hydraulic power booster (1) and the master cylinder. It is suggested to provide a valve device (49) which in case of control may be switched over and by means of which two wheel brakes (52, 53) of one axle may be connected with each other. The wheel brakes of one brake circuit each are arranged at the vehicle so as to diagonally oppose each other. By using such means a hydraulic brake system is realizable which in the case of normal brake actions has a diagonal brake circuit allotment and in which in case of control caused by slip detection two wheel brakes (52, 53) of one vehicle axle are connected with each other, the brake system thus working with a Y-brake circuit allotment during brake slip control.

    摘要: In a road vehicle braking system incorporating wheel slide protection, sensing apparatus provides a signal representing the rotational deceleration of a vehicle wheel, and brake control apparatus responsive to said signal releases the brakes from the wheel when the magnitude of the signal exceeds a predetermined value. The power for the system is derived from a battery on the vehicle by way of switching apparatus, and fault sensing means is provided for turning the switching means off so that the system reverts to normal braking when a given fault occurs in the system.

    摘要: The yaw moment reducing device comprises wheel speed sensors for detecting the speeds of the right and left wheels, an acceleration calculation device for calculating accelerations of the right and left wheels based on the speed of the right and left wheels, a substraction device for subtracting the difference in accelerations between the right and left wheels, a braking control device for controlling the braking force based on the difference of the accelerations, and a brake pressure modulating device for modulating the brake pressure which is supplied to each wheel. The wheel speeds of each wheel are detected by the wheel speed sensors. The acceleration calculation device calculates the accelerations of each wheel while the substraction device provides the difference in accelerations between the right and left wheels. The yaw moment is in response to the difference of the acceleration between the right and left wheels. In other words, the yaw moment can be presumed by the difference of the acceleration between the right and left wheels. The brake pressure modulating device modulates the brake pressure which is supplied to each wheel based on the calculation result of the braking control devices. Thus, the yaw moment can be controlled.

    摘要: The invention is directed to an arrangement for controlling a braking force applied to each of road wheels of a rear drive vehicle depending upon a braking condition, with a hydraulic braking pressure supplied to each of wheel brake cylinders through pressure control valves respectively. The pressure control valves are controlled by the braking force controller into which output signals of wheel speed sensors are fed. In a first determination unit, it is determined if at least one of the front road wheels is on a road surface of a coefficient of friction lower than a predetermined value, and determined if the front wheel speed of one of the front road wheels has reached to a peak wheel speed. And, in a second determination unit, it is determined if a difference between the front wheel speed and rear wheel speed is less than a predetermined speed. When it is determined that at least one of the front road wheels is on the road surface of the low coefficient of friction and the front wheel speed has reached to the peak wheel speed, and that the difference between the front and rear wheel speeds is less than the predetermined speed, an asynchronous control unit prohibits the braking force controller from synchronously controlling the braking force applied to the front road wheels.

    摘要: The circuit comprises a primary circuit (2) feeding brake motors (5) and (7) and a secondary circuit (3) feeding a brake motor (9). In normal operation a valve (11) isolates the brake motor (22) from the secondary circuit (3). The pressure in the primary circuit then controls the pressure prevailing in the brake motor (22) with the aid of a pressure balancing device (25) installed between the feed lines of the brake motors (7 and 22). In the event of the failure of the primary circuit (2) the valve (11) establishes communication between the brake motor (22) and the secondary circuit (3) to effect the braking of the wheel associated with the brake motor despite the fact that the balancing device (25) is put out of action in this situation. Application to a brake circuit equipped with an anti-wheel-lock device.
