  • Patent number: 10443289
    Abstract: A system controls opening/closing of a power swinging door, e.g., in a vehicle, and includes a rotary actuator, position sensor, and controller. In a controller-executed method, the actuator applies torque to the door in response to control signals. The controller uses a measured raw angular position from the sensor to determine wind- or grade-based external forces acting on the door during opening or closing, and adjusts the actuator torque in response to the external forces. The sensor may be a rotary encoder, with the actuator being an electric motor. Lookup tables contain data relating oscillation to the external forces. The controller may induce door oscillation and to relate oscillation decay to the external forces. An obstacle-based current threshold may be adjusted in response to the external forces.

  • Patent number: 10377377
    Abstract: A blind zone mitigation system of a host vehicle comprises i) at least one sensor that determines position information of a target vehicle with respect to the host vehicle, and ii) an active lane positioning module. The active lane positioning module receives the position information from the at least one sensor and determines a blind zone of the target vehicle. The active lane positioning module, in an active lane position mode, accelerates the host vehicle to move the host vehicle out of the blind zone of the target vehicle or decelerates the host vehicle to move the host vehicle out of the blind zone of the target vehicle.

  • Publication number: 20180043895
    Abstract: A soft-park control system to control vehicle movement during parking of a vehicle includes a transmission and one or more brake assemblies. The transmission includes a parking pawl that mechanically engages a notch in a parking gear. The brake assembly includes an electro-mechanical actuator configured to apply a variable brake force to a wheel coupled to a brake assembly based on an existing brake pressure. The soft-park control system further includes an electronic control unit having a soft-park hardware controller in electrical communication with the electro-mechanical actuator. The electronic brake control unit outputs a brake pressure signal that adjusts the existing brake pressure so as to control a rate at which the parking pawl engages the notch.

  • Patent number: 9849924
    Abstract: A vehicle includes a body, an aerodynamic element, a movement mechanism, a plurality of sensors, and a controller. The body is located along a longitudinal axis and a lateral axis. The aerodynamic element intersects ambient airflow, which generates an aerodynamic force. The movement mechanism moves the aerodynamic element, relative to the body, along the longitudinal and lateral axes. The sensors collectively generate input signals corresponding to an operating condition of the vehicle. The controller determines a current position of the movement mechanism, corresponding to a current location of the aerodynamic element on the axes and determines a desired position of the movement mechanism, corresponding to a desired location of the aerodynamic element on the axes. The controller transmits a movement signal to the movement mechanism to change position from the current position to the desired position, such that the aerodynamic element moves from the current location to the desired location.
