摘要： A pressure supply system for a vehicle according to the invention incorporates a pump and an accumulator in which an output pressure of the pump is maintained within a prescribed range by controlling the on-off operation of the pump according to the inner pressure of the accumulator. By changing the prescribed range of pressure according to the actual pressure requirement, for instance according to the change in the travelling speed of the vehicle, the burden on the system is reduced. The prescribed range can be changed either by simply changing the upper and/or lower pressure limits at which the pump is deactivated and activated, respectively, or by operating the pump for a prescribed time period which is dependent on the pressure requirement after a certain reference pressure value is reached. Thus, the structure of the fluid pressure system is simplified, and the generation of unnecessary high pressure can be avoided.

摘要： In a hydraulic braking pressure control system including an auxiliary hydraulic pressure generating unit capable of generating a hydraulic pressure in accordance with the braking operation of a brake pedal, and a hydraulic pressure supply source hydraulic pressure control unit interposed between a hydraulic pressure supply source and a brake device for controlling the hydraulic pressure from the hydraulic pressure supply source in accordance with the braking operation of the brake pedal, the hydraulic pressure chamber in the auxiliary hydraulic pressure generating unit is connected to the supply source hydraulic pressure control unit, so that the output hydraulic pressure therefrom is applied as a control pressure. When the hydraulic pressure from the hydraulic pressure supply source has been abnormally reduced, a braking pressure from the auxiliary hydraulic pressure generating unit is applied to the brake device in response to an opening of the on-off valve. During braking in a condition in which the hydraulic pressure from the hydraulic pressure supply source is normal, the operation of the hydraulic pressure regulating unit avoids the hydraulic pressure from the auxiliary hydraulic pressure generating unit from being applied to the brake device.

摘要： A hydraulic braking pressure control apparatus provided with a modulator for controlling the supply of control hydraulic pressure to a wheel brake of the vehicle, wherein a partition is provided between a first cylinder portion and a second cylinder portion which are formed in a casing, a first piston adapted to divide the first cylinder portion into an input hydraulic chamber on the partition side and a control chamber on the opposite side is secured to one end of a piston rod extending through the partition slidably and oil-tightly, and a second piston adapted to define an output hydraulic chamber on the partition side within the second cylinder portion is mounted on the other end of the piston rod for axial relative movement. The partition is provided with a valve mechanism capable of disconnecting communication between the input and output hydraulic chambers. The second piston is biased in a direction toward the partition, and by relative movement of the second piston with respect to the piston rod, the interior of the output hydraulic chamber is prevented from reaching an excessive negative pressure level during an anti-lock operation. The apparatus can function as a proportioning reducing valve by forming the first piston with a smaller diameter than the second piston.

摘要： A system for controlling running safety of a vehicle having an alarm and an automatic braking system. A plurality of decelerations &agr;2n of an obstacle such as another vehicle present ahead on the road is predicted and corresponding manipulated variables &agr;1n (braking amount) to be supplied to the vehicle which indicate possible deceleration of the vehicle are determined. Then threshold values L&agr;2n for alarming and automatic braking are determined corresponding to the predicted deceleration and are successively compared with the distance to the obstacle. When the distance falls below any of the threshold values, alarming or automatic braking is effected to avoid contact with the obstacle, thereby making the system relatively simple and enabling operation to match the driver's expectations.

摘要： A vehicle includes a plurality of axles including front and rear axles on which wheels are mounted at opposite ends thereof, wheel brakes mounted to the wheels, wheel speed detectors for detecting wheel speeds of the wheels, actuators for operating the wheel brakes, and a friction coefficient determining device for determining a friction coefficient of a travel road surface based on detection values detected by the wheel speed detectors. When each of the wheels is braked, the operations of the actuators are controlled such that braking forces are generated only in the wheel brakes in one of the axles at least at an initial stage of the braking, and the determination of the friction coefficient by the friction coefficient determining device is carried out at the initial stage. Thus, the determination of the friction coefficient by the friction coefficient determining device is more facilitated.

摘要： In a braking-force distribution control system for a vehicle, which is capable of controlling the ratio of a braking liquid pressure for front wheels to a braking liquid pressure for rear wheels based on a comparison of front and rear wheel speeds, a correcting factor is calculated in a correcting factor calculating device based on the ratio of front and rear wheel rotational speeds detected by front and rear wheel rotational speed sensors. At least one of front and rear wheel speeds, calculated in front and rear wheel speed calculating devices, is corrected by a wheel speed correcting device prior to the calculation of a control quantity in a control quantity calculating device. A control determining device determines whether the range of variation in correcting factor is equal to or larger than a preset value. When the range of variation in correcting factor is equal to or larger than the preset value, a signal indicative of a command to prohibit the calculation of the control quantity based on the result of the comparison of the front and rear wheel speeds in the control quantity calculating device is output from the control determining device. Thus, it is possible to perform an appropriate control of braking-force distribution taking a variation in dynamic radius of a tire into consideration.
