摘要： An antiskid brake system for an automotive vehicle is provided which includes a parameter determining circuit and a braking condition determining circuit. The parameter determining circuit determines a parameter reflecting on brake torque applied to a wheel of the vehicle. The braking condition determining circuit compares the phase of a change in speed of the wheel with the phase of a change in the parameter to determine a phase delay of the change in speed of the wheel and determines the braking condition based on the phase delay, thereby allowing a wheel skid used in the antiskid brake control precisely without employing parameters such as vehicle speed and wheel speed as employed in conventional antiskid brake systems.

摘要： In a vehicle hydraulic brake system of a type adapted to release brake fluid discharged from the wheel cylinders into a reservoir for a master cylinder during pressure reduction phase of antilock brake control or vehicle stability control, the volume of the pressure chamber of the master cylinder can decrease until it becomes impossible to further increase pressure as a result of repeated pressure increase and reduction. An inexpensive solution to this problem is provided. The solution includes means for estimating the amount of pressure increase and/or pressure reduction of the wheel cylinders, and solenoid valves provided in a line connecting a pressure source with the master cylinder pressure chamber and adapted to be opened for a calculated time period.

摘要： The invention relates to an arrangement (11) for ensuring the functionning of a brake configuration for a vehicle with a multiplicity of wheels which are arranged with reference to a front axle and at least one rear axle and which support the vehicle, the brake configuration incorporating at least two brake devices (5a-f), each of them designed to act upon one of said wheels, and a brake control (12) with which the brake devices (5a-f) can be activated with a total brake action. The arrangement (11) incorporates a memory unit (14) designed to store at least one value of a parameter for said brake devices, said parameter relating to at least one previous braking operation performed by the respective brake device (5a-f), and a control unit (13) designed to distribute said brake action to said brake devices (5a-f), taking into account the value of said parameter of the respective brake devices (5a-f) when the brake control (12) is actuated. Said brake devices (5a-f) preferably consist of disc brakes and the value of said parameter indicates to what extent a film has accumulated on the brake lining surfaces which come into contact with the respective discs, which film reduces the friction between discs and brake linings at least incipiently. If the value indicates that such a film has formed, the whole or a major portion of the brake action called for by the driver, i.e. the total brake action, is distributed to the disc brakes (5a-f) whose value of said parameter indicates the presence of such a film.

摘要： An anti-skid control system for an automotive vehicle includes a hydraulic modulator having electromagnetic solenoid valves for regulating a wheel-brake cylinder pressure at each of road wheels. A skid control unit prevents a wheel lock-up condition by controlling the wheel-brake cylinder pressure via on/off reaction of the solenoid valves in response to a pulse signal based on a wheel speed detected by a wheel speed sensor. The skid control unit has a data processing section that generates a desired wheel speed based on the wheel speed, calculates a desired brake-fluid pressure based on an integrated value of a wheel-speed deviation between the desired wheel speed and the wheel speed, sets a controlled ON pulse width based on the desired brake-fluid pressure, and outputting the pulse signal having the controlled pulse width to the solenoid valves after a lapse of a preset pulse width from a previous pulse signal output.
