Patent number: 10443289Abstract: 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.Type: GrantFiled: June 27, 2017Date of Patent: October 15, 2019Assignee: GM Global Technology Operations LLCInventors: Besi Rrumbullaku, Constandi J.

Patent number: 9849924Abstract: 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.Type: GrantFiled: December 7, 2015Date of Patent: December 26, 2017Assignee: GM Global Technology Operations LLCInventor: Constandi J.
