摘要： In a braking pressure control apparatus for a vehicle, a first valve connected between a hydraulic pressure source and a wheel cylinder serves to permit and inhibit a supply of brake fluid to the wheel cylinder from the hydraulic pressure source. A second valve connected between the wheel cylinder and a reservoir serves to permit and inhibit an escape of the brake fluid from the wheel cylinder toward the reservoir. A control device serves to output control signals to the first and second valves respectively to control the braking pressure in the wheel cylinder in response to a detected running condition of the vehicle. The control device includes a deciding section for deciding whether or not a small variation in the braking pressure in the wheel cylinder should be done on the basis of the detected running condition of the vehicle, and an outputting section for, when the deciding section decides that the small variation in the braking pressure in the wheel cylinder should be done, simultaneously outputting the control signals to the first and second valves to simultaneously execute the supply of the brake fluid to the wheel cylinder and the escape of the brake fluid from the wheel cylinder.

摘要： An anti-skid brake system for the automotive vehicle is disclosed which is arranged to increase or decrease the braking oil pressure periodically on the basis of a comparison between the wheel speed and the assumed vehicle body speed. When the state in which the wheel is incipient to lock before the wheel speed is returned to the assumed vehicle body speed, the braking oil pressure is inhibited from being increased, thereby preventing the assumed vehicle body speed from deviating too far from the actual vehicle body speed. This anti-skid brake system can prevent the wheel from being locked due to having the assumed vehicle body speed set to too low a value relative to the actual wheel speed.

摘要： Brake force proportioning system for a vehicle includes a two-way valve in the line between a diagonally connected front and rear wheel. A controller opens the valve continuously in a first region of brake pressure so that the brake force proportioning follows a fixed proportioning characteristic. Outside this region the valve is opened in pulses so that the proportioning follows an ideal characteristic curve. If the controller fails, a pressure limiting valve takes the place of the two-way valve and effects a pressure distribution according to a characteristic parallel to the fixed slope characteristic.

摘要： A brake system with anti-lock and/or traction slip control, wherein quantities (.DELTA.t.sub.EV, .DELTA.t.sub.AV) determining the pressure in the wheel brakes (10, 11) are measured and assessed. A wheel pressure pattern (p(t)) is formed from these quantities by integration which, by approximation, represents the pressure variation in the wheel brakes (10, 11). The output signal of the integrator (20) is fed back to the control logic (16) and assessed for slip control and/or braking pressure control. For the integration, taken into account are the braking-pressure-increase and braking-pressure-decrease characteristic curves (P.sub.A, P.sub.E) and the initial conditions (21) which represent the initial pressure upon commencement of the control.

摘要： When ASR is running, the driver can brake at any time and does not encounter a stiff brake pedal. The ABS is equipped with an aspirating return pump which serves as a pressure producer in the ASR case with the aid of two auxiliary valves, i.e. a changeover valve and a loading valve. The brake pressure on the wheel on a selected axle that first shows a tendency to slip is modulated by way of the auxiliary valves, while the brake pressure on all other wheels is modulated by the ABS valves. In this manner brake pressure can always reach at least one wheel brake. If the ABS responds, the ASR is shut off.

摘要： An air brake system for a truck includes a treadle valve, a pilot control isolation valve, an exhaust valve, a relay valve, an air pressure transducer, a wheel speed sensor, an electronic control unit (ECU) and an air brake chamber associated with a brake actuator. In heavy braking operations, the pilot system pressure rise rate is monitored and restricted by modulation of the pilot control isolation valve. During heavy braking operations, if braking of the vehicle wheel results in a wheel velocity change which exceeds a predetermined deceleration threshold, the pressure rise rate is further restricted in attempt to "creep" up on the brake system pressure at which the lock condition is expected to occur. At another predetermined deceleration threshold, the brake system pressure is vented. The brake system pressure decreases resulting in a reduction in the applied brake force thereby permitting the vehicle wheel to roll back up to speed. The roll up rate is a function of the friction force. The friction force is used to control parameters of operation of the antilock brake system during subsequent antilock cycles.

摘要： A brake system wherein an auxiliary power based on a manual force is electronically controlled to control the braking force so as to obtain braking effects corresponding to a manual control input. The braking force is controlled so that a vehicle deceleration corresponding to the control input can be obtained when the control input is equal to or greater than a comparatively small predetermined control input value Lo. When the control input is smaller than Lo, the braking force is controlled so that the vehicle acceleration will not exceed a value corresponding to the control input.

摘要： A process is described for controlling the brake pressure wherein a brake pressure is supplied which corresponds to the desired signal. This pressure is measured. The factors b.sup.+/- and the response times T.sub.o.sup.+/- are identified from the pressure pulses P in the individual control cycles and the actuating times .+-.T of the valves and they are used to convert the desired signal P.sup.x into a control signal .+-.T of such a length that the desired pressure is supplied.
