Abstract: A power latch assembly for a vehicle door of a motor vehicle includes a ratchet configured for movement between striker capture and striker release positions, wherein the ratchet is biased toward the striker release position, and a pawl configured for movement between a ratchet holding position, whereat the pawl maintains the ratchet in the striker capture position, and a ratchet releasing position, whereat the pawl releases the ratchet to the striker release position. A powered actuator is energizable to move the pawl from the ratchet holding position to the ratchet releasing position, and a multistage mechanism operably connecting an output of the power actuator to at least one of the pawl and the ratchet has at least two power takeoffs, with each power takeoff being configured to apply a different torque output to at least one of the pawl and/or the ratchet.

Abstract: A motor control system for controlling a brushless electric motor of a power operated actuator of a closure panel of a vehicle and method of operating the control system are provided. The control system includes a vector control system configured to receive a torque current based on a measured angular velocity of the motor and current of each of the phases and determine corresponding stationary reference frame voltages. The vector control system outputs pulse width modulation signals to the motor. A vector torque current limiter couples to the vector control system and the motor and is configured to determine the torque current drawn, receive the measured angular velocity and determine whether there is a reduction of the measured angular velocity and detects a pinch event and reduces the torque current in response to determining there is a reduction of the measured angular velocity of the brushless electric motor.

Abstract: A closure latch assembly having a latch mechanism is provided. The latch mechanism includes a ratchet and a pawl assembly pivotally supported for movement between a ratchet holding position whereat the pawl assembly is positioned to hold the ratchet in its striker capture position and a ratchet releasing position whereat the pawl assembly is located to permit movement of the ratchet to its striker release position. The pawl assembly has a carrier and a pawl configured for rotation relative to one another about a pawl pin and a roller carried by the carrier. The roller is disposed between the pawl and the ratchet for selective rolling movement therebetween. The roller is disposed into abutment with a closing surface of the ratchet while the pawl assembly is in the ratchet holding position and is spaced from closing surface while the pawl assembly is in the ratchet releasing position.

Abstract: A lifter plate assembly for a window of a motor vehicle has a plastic main body. The main body includes a pair of rail guide hooks formed therein. The rail guide hooks are laterally spaced from one another and configured for sliding receipt of window regulator rails therein. A window clamp plate formed of the main body plastic extends in spaced relation from the main body to provide a receptacle configured for receipt of an edge of the window. A fastener assembly includes an elongate threaded member and a nut. The elongate threaded member extends through an opening in the main body and through an opening in the window clamp plate. At least one of the elongate threaded member and the nut is rotatable relative to the other to draw the window clamp plate and the main body toward one another to clamp against the edge of the window.

Abstract: An electronic latch system for a motor vehicle includes an electronic latch (e-latch) including an e-latch controller within a door of the vehicle. A plurality of radar sensors are located within the door for performing non-contact detection of objects around the vehicle. The radar sensors include an outside-face sensor adjacent an outside face of the door to sense an object within a first sensing zone extending from the outside face. The radar sensors also include an inner sensor adjacent an inside surface of the door to sense an object within a second sensing zone extending from the inside surface. The radar sensors also include a shut-face sensor adjacent a shut face of the door to sense an object within a third sensing zone extending from the shut face. The e-latch includes a light source for projecting a warning image and an audio source for generating an audible warning.

Abstract: A sensor assembly for detecting an object is disclosed. The sensor assembly includes at least one radar transmitter configured to emit transmitted radar waves having a first polarization. The sensor assembly also includes at least one radar receiver configured to receive the transmitted radar waves after reflecting from the object as reflected radar waves having a second polarization different than the first polarization and corresponding with a detection of the object relative to the sensor assembly. The at least one radar receiver is additionally configured to reject radar waves having a polarization being different than the second polarization to disregard noise generated by environmental interaction of the transmitted radar waves and from extraneous radar sources.

Abstract: An active hinge including a hood bracket for attachment to a vehicle hood and a body bracket for attachment to a vehicle body. A deploy bracket is pivotally attached to the hood bracket and the body bracket. The hood bracket is pivotable relative to the deploy bracket between a non-deployed position and a deployed position. At least one link interconnects, and is pivotally connected to the deploy bracket and the body bracket. A pawl is pivotally mounted to one of the hood bracket, the body bracket, the deploy bracket, and the at least one link. A bolt for engagement by the pawl is connected to another of the hood bracket, the body bracket, the deploy bracket, and the at least one link. An actuator is provided for disengaging the pawl from the bolt to allow the deploy bracket to move relative to the hood bracket and the body bracket.

Abstract: A latch assembly for a closure panel and corresponding method of operation are provided. The assembly includes an actuation group to latch and unlatch the closure panel using power from a main power source during normal operation. A first backup energy source is selectively coupled to the actuation group and stores energy during normal operation and supplies the energy during a failure. A second backup energy source is selectively coupled to the first backup energy source and supplies energy thereto during the failure. A latch controller is coupled to the backup energy sources and detects latch operation and whether there is normal operation. The latch controller charges the first backup energy source using energy from the second backup energy source based on the detection of latch operation and the failure and disconnects the second backup energy source during normal operation to conserve energy stored in the second backup energy source.
