摘要： The anti-skid control system is capable of performing highly reliable anti-skid control through its accurate estimation of the vehicle speed and proper compensatory control even when sharp braking occurs or in the brake fluid pressure control on road surfaces with a low coefficient of friction likely to cause considerable fluctuations in wheel acceleration. The anti-skid control system is provided with a fluid pressure generating device, a fluid pressure controlling device, a wheel velocity detecting device, a standard speed setting device, a fluid pressure controlling mode setting device which sets either the pressure decrease mode or the pressure hold mode when the wheel velocity declines to a level lower than the standard speed and sets the pressure increase mode when the wheel velocity is equal to or higher than the standard speed. A maximum inflection point detecting device detects the maximum inflection point indicating the maximum value for the shift of the wheel velocity mentioned above from an increase to a decrease when the wheel velocity is not any lower than the standard speed. A fluid pressure controlling mode correcting device switches from the pressure increase mode mentioned above to either the pressure hold mode or the pressure decrease mode when the wheel velocity becomes equal to or higher than the standard speed and also becomes equal to or higher than the wheel velocity at the maximum inflection point.

摘要： The invention is directed to an arrangement for controlling a braking force applied to a road wheel, with a hydraulic braking pressure supplied to a wheel brake cylinder through an actuator. A standard speed is set on the basis of a wheel speed detected by a wheel speed sensor, and a peak of the wheel speed changing from increase thereof to decrease thereof is detected. A coefficient of friction of road surface is determined on the basis of a vehicle acceleration detected by an acceleration sensor. The actuator is controlled according to a pressure control mode selected from a decrease mode for decreasing the pressure, a hold mode for holding the pressure, a first increase mode for increasing the pressure when the wheel speed exceeds the standard speed, and a second increase mode for increasing the pressure when the wheel speed exceeds the peak of the wheel speed. The first increase mode is selected when the coefficient of friction exceeds a predetermined value and the standard speed exceeds a predetermined speed. The second increase mode is selected when the standard speed is lower than the predetermined speed.

摘要： The invention is directed to an anti-skid control system for controlling a braking force applied to each of the road wheels with a hydraulic braking pressure supplied to a wheel brake cylinder through pressure control means. A wheel speed of each of the road wheels is detected. Then, an estimated vehicle speed for each of the road wheels is calculated on the basis of the wheel speed and a decreasing rate of estimated vehicle speed for at least one of the road wheels other than the road wheel for which the estimated vehicle speed is being calculated. The estimated vehicle speed is, therefore, prevented from being set largely below the actual speed of the vehicle. The pressure control means is provided for increasing, holding or decreasing the hydraulic braking pressure in response to a result of comparison between the estimated vehicle speed and the wheel speed for each of the road wheels.

摘要： The invention is directed to an arrangement for controlling a braking force applied to each of right and left road wheels individually depending upon a braking condition, with a hydraulic braking pressure supplied to each of wheel brake cylinders through actuators respectively. The actuators are controlled by the braking force control system wherein output signals of wheel speed detectors are fed into first and second detecting circuits respectively by which the braking conditions of the road wheels are detected. Then, the detected signals are fed into a first driving circuit which produces driving signals fed to the actuators on the basis of an output signal fed from either of the detectors for one road wheel having a tendency to be locked first. One of the actuators provided for the road wheel on the road surface of the lower coefficient of friction is driven by a driving signal fed from the first driving circuit, whereas the other actuator is driven by a driving signal which is fed from the first driving circuit and modified thereafter by the second driving circuit in response to a value representing a vehicle speed so as to increase the hydraulic braking pressure rapidly when the vehicle is driven at low speed, consequently shortening the stopping distance.

摘要： A brake pressure control device for use in an anti-skid control system decreases the slipping of a car wheel by reducing the car wheel brake pressure when the slipping of the car wheel against the road surface is excessive at the time of applying a brake pressure to the car wheel brake. The brake pressure control device includes a valve body having a first input port, a second input port, an output port, a spool valve with an annular recess communicating the ports, a spring biasing the spool valve toward a first position, a pressure chamber connected to the output port for applying pressure to the spool to move the spool toward a second portion and an electric coil for applying a force to move the spool toward the first position. Thus, the car wheel brake pressure can be controlled in proportion to the current supplied to the coil.

摘要： An air lumbar support is provided for establishing a desired attitude of a driver's seat of a vehicle, and is associated with an attitude control system. A pad of a seat back is supported by a plurality of air bags, each of which is connected with a solenoid valve, which when open, permits the air to be discharged into the atmosphere from the air bag. When a desired attitude is to be established, air under pressure is fed to the air bags. Attitude establishing data is in the form of a number of times the solenoid valves are energized for opening for short intervals, and is stored in a non-volatile semiconductor read-write memory if the attitude is to be registered. In response to a key operation, a microprocessor reads registered data automatically, initially driving an air pump, followed by opening the solenoid valves a number of times indicated by the data, thus establishing a desired air pressure in the air bag. In another embodiment, the solenoid valves are interposed between the air pump and the air bags.
