    摘要: A system and method for controlling vehicle roll, such as during a cornering maneuver. The roll control system and method include a sensor for sensing roll of the vehicle, a roll control signal generator for generating a roll control signal in response to the sensed vehicle roll, a pressure differential valve for generating a high pressure fluid, and an actuator for compensating for the sensed vehicle body roll. The roll control system and method also include a fluid control device for controlling the actuator in response to the roll control signal. The control device ports both the actuator inlet and outlet to a fluid reservoir when the vehicle is driven along a straight line path, and ports one of the actuator inlet and outlet to the fluid reservoir and the other of the actuator inlet and outlet to the high pressure fluid when the vehicle is driven along a curved path.

    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: An electromagnetic valve for use in controlling fluid flow between first and second passageways in a hydraulic valve block includes a valve body. The valve body defines a central axis, has a central opening therethrough, and has a lower end adapted to be inserted into a bore of the valve block. A hollow valve dome is attached to an upper end of the valve body. An armature is axially moveable within the valve dome. A spring biases the armature in one axial direction. A closing element is coupled to a lower end of the armature. An electromagnetic coil coaxially surrounds the armature and is operable to effect axial movement of the armature in an axial direction opposite the one axial direction. A valve seat member is carried by a lower end of the valve body and has an orifice providing fluid flow between the first and second valve block passageways. The valve seat member defines a valve seat that surrounds the orifice and cooperates with the closing element for selectively closing the orifice. The valve seat member is formed as a deep drawn part and includes a tubular portion having one end defining a valve seat, and an opposite end connected to the valve body.

    摘要: A control valve includes a magnetic pole member. An armature is slidably supported relative to the magnetic pole member for movement between a fully open position and a closed position. A biasing spring is disposed between the magnetic pole member and the armature for forcing the armature away from the magnetic pole member. A coil is placed about the magnetic pole member and the armature for inducing a magnetic field for moving the armature toward the magnetic pole member. One of either of the magnetic pole member or the armature has a recess for non-contactingly receiving the other when the armature moves between the fully open and closed positions. The control valve can be embodied as a normally open valve or a normally closed valve. The use of dual lateral poles and triple lateral poles create a flat magnetic force versus travel curve thereby allowing for greater proportional control of the valve. Additionally, the use of double lateral gaps and triple lateral gaps respectively results in force increases of 21% and 12% respectively. Compounding the force increases results in a net additional force of 36%.

    摘要: A coil assembly for a solenoid valve includes a bobbin formed from an electrically insulative material. A bore extends axially through the bobbin. A first flux ring having a sleeve extending axially from an annular base is mounted upon a first end of the bobbin with the sleeve extending into the bobbin bore. Similarly, a second flux ring also having a sleeve extending from an annular base is mounted upon a second end of the bobbin that is opposite from the first flux ring with its sleeve extending into the bobbin bore. The flux rings are formed from a magnetically permeable material that has a high heat conductivity. Magnet wire is wound upon the assembled bobbin and flux rings to form the coil assembly.

    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.
