Abstract:
A manually operated cable release apparatus, suitable for use in an electrically actuated brake, is provided for a locking mechanism having a shaft that is rotatable about an axis of rotation of the shaft, between a first angular position where the locking mechanism is disengaged, and a second angular position where the locking mechanism is engaged. The cable release apparatus includes a lever having one end thereof fixedly attached to the shaft and extending outward from the shaft for applying a force to the lever, for rotating the shaft back and forth through an angular displacement between the first and second angular positions. A cable is operatively connected to the lever in a manner allowing the shaft to rotate freely back and forth through the angular displacement of the shaft between the first and second angular positions without movement of the cable from a non-engaged position of the cable, and for engaging and applying a tensile force from the cable to the lever for rotating the shaft to the first position from any point in the angular displacement between the first and second angular positions of the shaft.
Abstract:
The problem of reliably locking an electrically actuated park brake is resolved through the use of a jaw-tooth clutch operatively installed between the shaft and the housing of a drive motor, for engaging the brake. The brake may be locked and unlocked by selectively engaging the jaw-tooth clutch either electrically or manually.
Abstract:
A voltage regulating control system for vehicle systems which includes a power supply providing electrical power to the system and having a predefined maximum voltage. A controller controls an actuator performing a vehicle system function and the electrical load in the system wherein the controller has a first predefined minimum operating voltage. A voltage regulator communicates with the controller and the power supply and senses a system input voltage in the system. In response to a sensed voltage dip in excess of a predetermined value, the regulator changes an effective electrical impedance of the system to maintain the system voltage at a predefined minimum voltage greater than the first predefined minimum operating voltage required by the controller.
