摘要： A method is disclosed for controlling operation of a motor-driven brake boost assist system of a vehicle braking system during a loss of battery power to the brake boost assist system. The method may involve detecting a condition during which a power loss event to the brake boost assist system has occurred, and a motor associated with the brake boost assist system is being driven by linear movement of a component within the brake boost assist system in response to fluid pressure developed within the brake boost assist system. The method further involves using a voltage generated by the motor during the power loss event to help initiate a dynamic braking action on the motor.

摘要： An assistance-limit recognizing device for recognizing a limit of assistance made by a vacuum booster that is configured to assist an operating force applied to a brake operating member. A communication between a variable pressure chamber and a negative pressure chamber of the vacuum booster is established, when the operating force is not applied to the brake operating member. A communication between the variable pressure chamber and the atmosphere is established while the communication between the variable pressure chamber and the negative pressure chamber is cut off, when the operating force is applied to the brake operating member, whereby the operating force applied to the brake operating member is assisted based on a pressure difference between a pressure in the negative pressure chamber and a pressure in the variable pressure chamber. The assistance-limit recognizing device is configured, upon reduction of the variable-pressure chamber pressure in process of change of the variable-pressure chamber pressure toward the atmospheric pressure with application of the operating force to the brake operating member, to recognize the limit of the assistance made by the vacuum booster.

摘要： An actuator assembly for a vehicle brake system comprises a piston disposed in a bore, a reservoir, and a solenoid. A channel is in fluid communication between the bore and the reservoir, and the solenoid is disposed in the channel. The solenoid is movable between an open position and a closed position. In the closed position, the solenoid blocks fluid communication between the bore and the reservoir.

摘要： A method and apparatus for activating a pump of a braking system for delivering a pressure medium, in which the creation of the activation signal, in particular the switch-on signal for the pump, is dependent on at least one condition. Creation of the switch-on signal of the pump is dependent on a pressure gradient variable, in particular on an accumulator pressure gradient. On the one hand this makes possible compensation for disturbances, for example the influence of temperature on the pressure medium, which is expressed as a small pressure gradient; and on the other hand it prevents the pressure from falling greatly below a lower threshold value in the event of a high volume demand request, i.e., prevents a severe pressure drop and thus a large pressure gradient.

摘要： A pedal simulator utilizing springs to provide a brake pedal with a non-linear, progressively increasing response characteristic for pedal travel versus force exerted on the brake pedal similar to a conventional hydraulic braking system. In a preferred embodiment, the pedal simulator is integrated into the housing of an associated master cylinder.
