摘要： In a braking control apparatus, a plurality of pumps are driven by a common first motor. A brake supplies operating fluid to pipelines by operating the first motor, and controls opening/closing of a fluid pressure regulating valve so as to make the wheel cylinder pressure in the right front wheel approach the right front wheel target pressure, and controls opening closing of a fluid pressure regulating valve so as to make the wheel cylinder pressure in the left rear wheel approach the left rear wheel target pressure. In the case where the right front wheel target pressure is zero when the fluid pressure regulating valve is to be opened so as to make the wheel cylinder pressure in the left rear wheel approach the left rear wheel target pressure, the brake turns off the first motor.

摘要： To make a brake device generate a required braking force, a hydraulic control section switches, according to the relative magnitude between the required braking force and a braking force exerted by braking operation, between drive of a pump motor and non-drive of the pump motor and a master cut valve reduces the flow of brake fluid in the direction to a master cylinder. By this, a wheel cylinder maintains hydraulic pressure capable of generating the required braking force. As a result, the pump motor is not necessarily always driven when the required braking force is generated, and the operating time period of the pump motor is reduced. As a result, a load on the pump motor is reduced to enhance durability of the pump motor.

摘要： The invention relates to a method for improving the control behavior of motor vehicle control systems such as ABS, ESP, etc. comprising electrically driven hydraulic pumps, inlet and outlet valves and low-pressure accumulators, wherein the low-pressure accumulators accommodate, at least in part, pressure fluid that is discharged from wheel brakes in a control operation, wherein the hydraulic pumps are used to return the pressure fluid into a master cylinder, in particular tandem master cylinder, wherein the delivery behavior of the hydraulic pumps is controlled in dependence on pressure values, wherein the actuation of the hydraulic pumps takes place in conformity with demand, i.e. by evaluating slip variation, wherein in a pressure increase phase, the pressure fluid is intermediately stored in the low-pressure accumulators and there is no return delivery of the pressure fluid into the master cylinder until either a pressure increase phase or pressure buildup commences, or a critical filling level of the low-pressure accumulator necessitates actuation of the hydraulic pumps for safety reasons, with the result of balancing the volume flow demand and the delivery volume flow and thus achieving a reduction of vibrations of the brake pedal. Further, the invention relates to a computer program product defining an algorithm that comprises a method for improving the control behavior of motor vehicle control systems.

摘要： In a pump operation control apparatus for a hydraulic brake boosting system, an ECU 13 is provided with a timer 16 to which an output signal from a brake switch 12 is supplied and a pump-operation-control-signal generating means 17 for transmitting a signal for operating and controlling a motor 9 in response to an output signal from the timer 16. When the brake switch 12 has been switched on, the operation of the pump is started. After predetermined time T has elapsed from a moment at which the brake switch 12 has been switched on, the operation of the pump is interrupted. If the brake switch 12 is continuously switched on after the predetermined time T has elapsed, the pump is operated for time elongated from the predetermined time T until the brake switch 12 is switched off. If the brake switch 12 is again switched on before the predetermined time T elapses, the pump is operated until the predetermined time T elapses from the moment at which the brake switch 12 has again been switched on.

摘要： The object to be achieved by the present invention is to improve accuracy in determining whether or not it is necessary to terminate antiskid control and to reduce the frequency with which the control is terminated. The solution proposed by the present invention is to stop operation of a hydraulic pump before it is determined that the antiskid control should be terminated during the duty pressure increase operation, whereby fluid pressure in a wheel brake can be raised to a level of fluid pressure in a master cylinder before it is determined that the antiskid control should be terminated, to continue the antiskid control as long as the wheel tends to be locked and to terminate the antiskid control when the wheel does not tend to be locked.

摘要： A pressure source for a pressure device includes a pump for pumping fluid from fluid tank, an accumulator connected to the pump and a pressure device, a device for detecting the pressure in the accumulator, and a controller for controlling the operation of the pump in an ON-OFF manner on the basis of a result of detection by the pressure detecting device. In this pressure source, the controller includes first and second drive signal generating circuits each capable of independently generating a drive signal for determining the on-off operation of the pump, and a judging circuit which has a calculating function therein and to which at least the pressure detecting device is connected. The judging circuit is connected to the first drive signal generating circuit, and the pressure detecting device is connected to the second drive signal generating circuit. This ensures that the control of the first drive signal generating circuit can be carried out at any time by a calculation in the judging circuit, leading to an increased function. When the judging circuit is in trouble, the on-off control of the pump can be carried out by the second drive signal generating circuit.
