摘要： A brake booster for a brake system of a vehicle, wherein the brake booster is in fluid communication with a source of pressurized fluid. The brake booster includes a housing having a bore formed therein and a conduit formed therein being in fluid communication with the bore and the source of pressurized fluid. The brake booster includes first and second pistons slidably disposed within the bore of the housing. The bore, the first piston, and the second piston define a fluid chamber in fluid communication with the conduit formed in the housing, wherein the volume of the chamber is defined by the position of the first piston relative to the second piston. The brake booster further includes a valve selectively preventing fluid flow in a direction from the chamber to the source of pressurized fluid via the conduit.

摘要： A method of controlling the operation of an electrohydraulic brake booster to achieve a desired pedal feel. The method includes sensing brake pedal movement from a fully retracted rest position before a significant resistance to travel of the brake pedal is developed. The method further includes generating a command pulse that results in application of pressurized hydraulic fluid to the boost piston assembly sufficient to overcome preloaded spring forces and seal friction in the boost piston assembly that would otherwise tend to resist further brake pedal travel. The method further includes providing a control signal override when a brake pedal "bounce" condition is detected to avoid undesired vehicle braking. A brake pedal bounce condition may occur if the brake pedal is released suddenly so that the brake pedal returns to the fully retracted rest position rapidly enough to bounce off of a mechanical stop at that position and move in the brake apply direction.
摘要翻译：一种控制电动液压制动助力器的操作以实现期望的踏板感觉的方法。该方法包括在制动踏板的显着阻力发展之前，从完全缩回的静止位置感测制动踏板的运动。该方法还包括产生指令脉冲，其导致加压液压流体施加到升压活塞组件，足以克服预加载的弹簧力并密封增压活塞组件中的摩擦，否则其将倾向于抵抗进一步的制动踏板行程。该方法还包括当检测到制动踏板“反弹”状况时提供控制信号超驰以避免不期望的车辆制动。如果制动踏板被突然释放，制动踏板反弹状态可能会发生，使制动踏板迅速返回到完全缩回的停止位置，足以弹出该位置的机械止动件并在制动器施加方向上移动。

摘要： The present invention provides a proportional microvalve having a first, second and third layer, and having high aspect ratio geometries. The first layer defines a cavity with inlet and outlet ports. The second layer, doped to have a low resistivity and bonded between the first and third layers, defines a cavity having a flow area to permit fluid flow between the inlet and outlet ports. The second layer further defines an actuatable displaceable member, and one or more thermal actuators for actuating the displaceable member to a position between and including an open and a closed position to permit or occlude fluid flow. The third layer provides one wall of the cavity and provides electrical contacts for electrically heating the thermally expandable actuators. The thermal actuators and the displaceable member have high aspect ratios and are formed by deep reactive ion etching such that they are displaceable in the plane of the second layer while being very stiff out of the plane. Thus, both actuation and displacement of the displaceable member are in the plane of the layer.

摘要： The present invention determines a longitudinal wheel speed of an individual wheel from an angular rate signal from a wheel rotation sensor. Vehicle suspension information or operating characteristics are input to a suspension system mathematical model to determine instantaneous rolling radius, taking into account changes in tire rolling radius resulting from vertical motion of the road surface. Improved accuracy of wheel speed permits less severe filtering of wheel speeds in detecting wheel slip and/or modified speed and acceleration thresholds in slip control.

摘要： A vehicle control system includes a steering mechanism adapted to be operatively connected to associated wheels of a vehicle. A position sensor is operatively connected to the steering mechanism to generate a signal representative of a position of the steering mechanism. A filter device receives the steering position signal and generates a filtered output. The electronic control unit is operable to generate a control signal based at least in part upon the filtered steering position signal. A vehicle control subsystem is in communication with the electronic control unit and is responsive to the control signal. A vehicle system is controlled by monitoring the position of a steering mechanism of a vehicle, determining a rate of change of the position of the steering mechanism, filtering the rate of change, comparing the filtered rate of change to a threshold value, and controlling a vehicle system based upon the comparison.

摘要： A manifold for distributing a fluid. The manifold can be used to distribute a fluid to and from a microvalve. The manifold includes a first plate having a groove formed in one face thereof. A second plate is fixed to the first plate so as to cover the groove to form a fluid passage through the groove. First and second bores are formed through at least one of the first plate and the second plate to form an inlet and an outlet, respectively, of the fluid passage. According to a method of manufacturing, etching the first plate forms the groove. Preferably, an etching process also forms the first and second bores. Also, preferably, the first plate is one of a plurality of plates formed from a single sheet of material. Preferably the sheet of material is a standard sized sheet with locating indicia enabling assembly of the manifold with standard pick and place equipment. Specifically, a method of assembling the manifold includes forming a plurality of first plates from a single sheet; a plurality of second plates from a second sheet; applying a braze material to selected portions of one of the first and second sheets; clamping the sheets together with each of the first plates aligned with a corresponding one of the second plates; heating the first and second sheets, and braze material therebetween, to braze each of the first plates to the corresponding one of the second plates to form a manifold; detaching each manifold from the first and second sheets; and assembling the manifold to a fluid circuit. Optionally, a microvalve is attached to each manifold before the manifold is detached from the first and second sheets.
