Patent number: 10053143Abstract: A controller for a power steering system estimates rack force and its derivative, such as based on lateral acceleration, yaw rate, vehicle speed, or other parameters. A control torque is calculated based on the rack force, its derivative, and the vehicle speed and is summed with an input torque from the driver to determine an amount of assist torque to provide. The control torque may be a shape function that has a sign determined by the sign of the derivative and a magnitude that decreases from a maximal value with increase in the magnitude of the rack force. The maximal value may be determined according to vehicle speed.Type: GrantFiled: November 7, 2016Date of Patent: August 21, 2018Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Dexin Wang, Timothy Gerard Offerle, Douglas Scott Rhode, Taehyun Shim, Yijun Li

Patent number: 9229452Abstract: A vehicle comprises a trailer angle detection apparatus and a trailer backup control system coupled to the trailer angle detection apparatus. The trailer angle detection apparatus is configured for outputting a signal generated as a function of an angle between the vehicle and a trailer towably attached to the vehicle. The trailer backup control system includes a jackknife enabling condition detector and a jackknife counter-measures controller. The jackknife counter-measures controller alters a setting of at least one vehicle operating parameter for alleviating an adverse jackknife condition during backing of the trailer by the vehicle when the jackknife enabling condition detector determines that a jackknife enabling condition has been attained at a particular point in time during backing of the trailer by the vehicle.Type: GrantFiled: June 3, 2014Date of Patent: January 5, 2016Assignees: Ford Global Technologies, The Regents of the University of MichiganInventors: Matt Y.
