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.

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.

Abstract: A method for testing to determine a coefficient of friction between a vehicle wheel and a surface with which the vehicle wheel is in contact (“surface mu”) includes the steps of calculating a surface mu confidence level based upon an evaluation of a locale of interest, an evaluation of visual cues sensed by the vehicle at the locale of interest, and/or an evaluation of vehicle signals at the locale of interest and scheduling the vehicle to perform active dynamic testing at the locale of interest. The method further includes the steps of performing the active dynamic testing, wherein the testing comprises commanding the vehicle to perform one or more of propulsion torqueing, regenerative torqueing, or brake torqueing of at least one wheel of the vehicle, receiving a measured parameter from the at least one wheel during said testing, and calculating a surface mu value for the locale of interest.

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.

Abstract: Systems and methods are provided testing a vehicle braking system. The method includes determining a nominal brake system parameter of the brake system during a braking operation. A first testing brake operation is performed and a first brake system parameter is determined based on the first testing brake operation. A tested brake system parameter is determined based on the first testing system parameter and the tested brake system parameter is compared to the nominal brake system parameter. A brake system compliance suspicion value of the vehicle braking system is then set based on the comparison.
