Publication number: 20230174149Abstract: A steer-by-wire system for a land vehicle, having a steering wheel, a feedback actuator, a detection device equipped to detect a driver's intention to enter the vehicle and/or a driver's intention to exit the vehicle, and an electronic control system, which, following detection of the intention to enter the vehicle and/or the intention to exit the vehicle controls the feedback actuator to hold the steering wheel in a predetermined rotational position by generating a holding torque. When an actuating torque which exceeds the holding torque is applied manually to the steering wheel and the steering wheel is rotated out of the predetermined rotational position, the electronic control system continuously approximates a turning angle of the predetermined rotational position to a turning angle of a current rotational position of the steering wheel using a specified time-based adjustment function based on a difference between the actuating torque and the holding torque.Type: ApplicationFiled: November 14, 2022Publication date: June 8, 2023Applicant: Ford Global Technologies, LLCInventors: Oliver Nehls, Sergio Codonesu, Jan Bremkens, Alexander Ein Waldt

Patent number: 10214238Abstract: A vehicle implements a steering anti-catch (SAC) algorithm that reduces a superimposition angle added to the steering wheel angle in order to reduce occurrence of steering catch. The superimposition angle may be determined according to an AFS system. The reduction of the superimposition angle according to the SAC algorithm is amplified when the driver is steering away from a center position, the vehicle speed is below a threshold, and a voltage for powering the power steering system is below a threshold. The amount by which the superimposition angle is reduced may be limited to a maximum reduction and may be subject to a limit in its rate of change as well.Type: GrantFiled: November 9, 2016Date of Patent: February 26, 2019Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Lodewijk Wijffels, Timothy Cannon, Cornelius Macfarland, Sergio Codonesu, David Michael Russell
