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.

Patent number: 9849911Abstract: A method for providing a warning that a trailer being towed by a vehicle will cross out of a travel lane when in a curve for the current vehicle path prior to the vehicle entering the curve. The method determines that the vehicle is approaching the curve, determines a radius of curvature of the curve, determines a lane width of the travel lane, and identifying a length of the trailer. The method also determines a predicted steering angle of the vehicle necessary to follow the radius of curvature of the curve, a turn radius of the vehicle for traveling through the curve using the predicted steering angle, and a turn radius of the trailer using the turn radius of the vehicle. The method then determines whether the trailer will cross out of the travel lane based on the curvature of the curve and the turn radius of the trailer.Type: GrantFiled: February 26, 2016Date of Patent: December 26, 2017Assignee: GM Global Technology Operations LLCInventors: Jin-Woo Lee, Bakhtiar B.

Patent number: 9853332Abstract: A battery pack, a device for sensing individual battery voltages in a battery pack and protecting the battery pack in the event of a circuit-breaking event, and a method for forming an encapsulant for the voltage-sensing circuit for use in a battery-powered automobile propulsion system. The battery pack includes numerous voltage sensing circuits with surface-mounted fuses and an encapsulant formed around each of the fuses. The encapsulant is robust enough to provide environmental isolation of the surface-mounted fuse such that the tendency of the fuse to form short-circuit connections to adjacent circuits is avoided under both normal battery pack operation and after a condition where the battery pack is compromised. The precursor to the encapsulant is made from a multiple layers of a traditional thin coating material or a single layer of a high-viscosity fluid to help maintain a minimum coating thickness around all exposed portions of the surface-mounted fuse, including the breech-prone corners.Type: GrantFiled: September 23, 2015Date of Patent: December 26, 2017Assignee: GM Global Technology Operations LLCInventors: Cammi L.
