Patent number: 10315481Abstract: Systems and method for assigning vehicle suspension dynamics are disclosed. Control signals that correspond to a current driving dynamic of a suspension system of a vehicle are generated. A vehicle state associated with the generated control signals is computed and a non-traditional suspension mode is selected. Based on the computed vehicle state and the selected suspension mode, a suspension height of the vehicle is adjusted.Type: GrantFiled: November 5, 2015Date of Patent: June 11, 2019Assignee: Ford Global Technologies, LLCInventors: Jianbo Lu, Davor David Hrovat, Eric Hongtei Tseng, Li Xu

Patent number: 9340228Abstract: A trailer backup assist system for a vehicle reversing a trailer includes a sensor module adapted to attach to the trailer and generate a trailer yaw rate or a trailer speed. The trailer backup assist system also includes a vehicle sensor system that generates a vehicle yaw rate and a vehicle speed. Further, the trailer backup assist system includes a controller that estimates a hitch angle based on the trailer yaw rate or the trailer speed and the vehicle yaw rate and the vehicle speed in view of a kinematic relationship between the trailer and the vehicle.Type: GrantFiled: October 13, 2014Date of Patent: May 17, 2016Assignee: Ford Global Technologies, LLCInventors: Li Xu, Eric Hongtei Tseng, Thomas Edward Pilutti, Steven Yellin Schondorf, Davor David Hrovat, John P.

Patent number: 9187076Abstract: Methods and systems are provided for reducing audible clunks and objectionable drive feel in vehicles including start/stop systems. In one example, a vehicle engine is shutdown during vehicle coasting. The vehicle engine is then restarted, while the vehicle is moving with a torque converter clutch disengaged. A transmission clutch pressure is then adjusted during the restart based on a torque converter output speed relative to a torque converter input speed.Type: GrantFiled: October 21, 2013Date of Patent: November 17, 2015Assignee: Ford Global Technologies, LLCInventors: Felix Nedorezov, Hong Jiang, Davor David Hrovat, Alex O'Connor Gibson
