摘要： A system and method of controlling engine vibration mounted within a vehicle including at least one hydraulic mount, each mount including a fluid chamber. A pair of accelerometers sense relative acceleration across the mount between the engine and the frame and generate a relative acceleration signal. A control unit is electrically connected to the accelerometers. The control unit is adapted to generate an electronic control signal in response to the relative acceleration signal. The control device is responsive to the electric control signal for controlling the damping force of the hydraulic mount. A control algorithm calibrates the control unit such that maximum vibration damping occurs at and around the engine resonance bounce frequency.

In another aspect, a brake pump assembly with a hydraulic block, a straight bore polymer piston, a peripheral sealing lip projecting from a proximal portion of the polymer piston, and a elastomeric seal mounted to a distal portion of the polymer piston, where the peripheral sealing lip selectively acts to depressurize fluid accumulating between the peripheral sealing lip and elastomeric seal.

摘要： A hybrid brake apparatus for a vehicle includes a front hydraulically actuated brake circuit, a rear electrically actuated brake circuit, and a controller. The front hydraulically actuated brake circuit includes a master cylinder for providing pressurized fluid to the front brake circuit in response to an input applied to the master cylinder for applying a frictional front braking force. The rear electrically actuated brake circuit is controllable in response to the input for providing a frictional rear braking force. The rear brake circuit is controlled in accordance with a first predetermined relationship between the input and rear braking force during normal operation of the front brake circuit. If the controller detects a degradation of front braking force, the rear brake circuit is controlled in accordance with a second predetermined relationship between the input and the rear braking force, to thereby compensate for the degradation of front braking force.
