摘要： A method for operating a brake system for motor vehicles comprises in a normal control mode of the system, a displacement of a piston for a pressure supply device is terminated, and inlet valves of the wheel brakes are closed in the event of a specified brake condition. The normal control mode is switched to a special control mode in the event of a specified condition for the pressure supply device. In the event of the specified brake condition in the special control mode, a displacement of the piston of the pressure supply device is terminated by outputting an actuation signal to the pressure supply device, and for at least one selected wheel brake, the corresponding inlet valve is kept open and the corresponding outlet valve is opened at least temporarily while the inlet valves of the remaining wheel brakes are closed.

摘要： A hydraulic system (10) having a pump (12) for sequentially supplying a brake booster (14) and a steering gear (16) with hydraulic fluid to an assist in effecting a brake application and/or a steering application. The brake booster (14) has a housing (100) with a chamber (102) therein connected to a first bore (104) which retains a piston (108) connected to a master cylinder (112) and a second bore (106) which retains a control valve (114). The second bore (106) has an inlet port (118) connected to the pump (12) for receiving supply hydraulic fluid, an outlet port (120) connected to the steering gear (16) and a return port (120) connected to the pump (12). Linkage (144) responsive to an input member (152) moves the control valve (114) to initially terminate communication from the second bore (106) to the return port (120) and direct the flow of a first portion of the supply hydraulic fluid to the chamber (102) to effect a brake application while a second portion thereof is communicated to the steering gear (16). A regulator (24) is connected to the pump (12) for receiving and directing the flow of supply hydraulic fluid to the inlet port (118) of the housing (100) of the booster (14). The regulator (24) responds to a preset hydraulic fluid pressure in the first portion of the supply hydraulic fluid by metering the flow of the supply pressurized hydraulic fluid to the inlet port (118) of the brake booster and thereafter directly communicating a corresponding portion of the supply hydraulic fluid through a port (210) to the steering gear (16). The regulator (24) on metering the supply hydraulic fluid to the inlet port (118) establishing a maximum limit for the hydraulic pressure in that portion of the supply hydraulic fluid presented to the control chamber (102) and to a chamber (182) in an associated accumulator (40).

摘要： A vehicle hydraulic brake system having brake pressure modulation valve assemblies, between a dual-circuit master cylinder and wheel brakes of vehicle wheels. The pump device is embodied as a low-pressure pump with the brake pressure modulation valve assemblies be assigned a first and second return pump and that in the automatic braking mode the first pressure chamber is made to communicate with a first return pump and the second pressure chamber is made to communicate with the second return pump, on the inlet side in both cases. The low-pressure pump, in the automatic braking mode, generates charge pressure for the return pumps that is substantially below a maximum brake pressure, and the return pumps generate the maximum projected brake pressure and serve, in the additionally possible anti-lock mode, to return pressure fluid from the wheel brakes to the master cylinder. The vehicle brake system is an inexpensive low-pressure pump that offers a high possible capacity of the return pumps in the automatic braking mode.

摘要： A braking system is disclosed that has a manually-actuatable master cylinder having two pressure chambers. A first pressure chamber hydraulically controls a flow control valve through which the pressure medium flows during servo-braking in order to adjust its regulating cross-section to produce a defined dynamic pressure that is applied to a first piston/cylinder arrangement, connected to the flow control valve, of a brake application element to produce a braking force. A second pressure chamber can be connected to a second piston of a brake application element so that a braking force can be applied to the brake application element if the servo-force fails. Also, instead of the second piston/cylinder arrangement, a separate separator piston/cylinder arrangement can be provided that is inserted between the second pressure chamber and the piston/cylinder arrangement. As a result, sufficient braking force is produced both in servo-force braking and if the servo-force fails. Also, an appropriate response by the braking forces to the master cylinder is effected so that there is always good actuating feedback.

摘要： A braking system including a pump for delivering a pressurized fluid toward two brake cylinders, an electrically operated pressure control device connected to a reservoir, pump and two brake cylinders, a controller for electrically controlling the pressure control device to control the pressures in the two brake cylinders, and a flow resistance control mechanism provided in a pump passage connecting the pump and the two brake cylinders. The mechanism operates to control fluid flows during operation of the pump such that when the pressures in the two brake cylinders have a relatively large difference, a resistance of fluid flow from the pump toward a low-pressure cylinder of the two brake cylinders is increased.
