摘要： The invention provides an electric brake system and method. The electric brake system includes an electric motor having a portion moveable along a path between a plurality of positions for moving a brake pad and applying a selectable amount of braking force on a brake rotor. One of the plurality of positions is a minimal contact position. The minimal contact position is operable to change among the plurality of positions over time. The electric brake system also includes an electric controller for controlling the electric motor to move the portion along the path between the minimal contact position and at least one other of the plurality of positions for moving the brake pad and for selecting the amount of braking force. The electric brake system also includes at least one sensor for sensing at least one of motor current, motor acceleration, controller voltage, motor speed, motor voltage, and motor temperature, and communicating a sensed condition to the controller. The controller is operable to change the minimal contact position in response to the condition sensed and communicated by the at least one sensor.

摘要： A shape memory alloy actuator includes a housing, a plunger, a shaft, a resilient member, and a shape memory alloy component. The plunger is slidably but non-rotatably received in the housing and has a first locking component. The shaft has a second locking component. The resilient member is positioned to slidably urge the plunger into a disengagement position of the first and second locking components allowing rotation of the shaft. The shape memory alloy component is positioned to slidably urge the plunger into an engagement position of the first and second locking components, when the shape memory alloy component is heated, preventing rotation of the shaft. In one application, the first and second locking components are interdigitable vehicle-parking-brake latch teeth.

摘要： A brake pedal feel emulator for a motor vehicle brake system includes a housing having a bore for supporting a first piston operably connected to a brake pedal. An elastomer spring encapsulating a magnet or magnetized by the dispersion of ferrous particles throughout the spring body is engageable by the first piston and is disposed in the emulator housing. A second piston is disposed in the housing and engaged with the elastomer spring and with a mechanical spring. Hall effect sensors mounted on the emulator housing sense changes in a magnetic field generated by the magnet to provide signals to a controller proportional to travel and force exerted on the brake pedal for use in controlling the vehicle brake system.
