Abstract: 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.

Abstract: Steer-by-wire steering systems for vehicles and related methods are described herein. An example steer-by-wire steering system includes a steering wheel angle sensor to detect a current steering wheel angle (α) of a steering wheel of the motor vehicle, a steering actuator to generate a variable steering torque on a steerable wheel of the motor vehicle, a steering angle sensor to detect a current steering angle (β) of the steerable wheel, and a steer-by-wire controller to process signals from the steering wheel angle sensor and the steering angle sensor and control the steering actuator based on the signals. The steer-by-wire controller is configured to vary a transmission ratio between a change in the steering wheel angle (α) and a change in the steering angle (β).

Abstract: Methods and systems are described for providing feedback in the event of a lane deviation of a vehicle having a power steering system. Vehicle data, such as speed, a steering angle, and the like, may be acquired (e.g., from a sensor system of the vehicle). An activation signal may be generated based on the acquired data. A haptic warning may then be generated using the power steering system of the vehicle based on the activation signal.

Abstract: Stabilization method and system for performing dynamic chassis control in a vehicle. An electronic stability control (ESC) includes an ESC sensor set; at least one chassis actuator; and a dynamic controller operably connected to at the least one chassis actuator. The ESC sensor set generates one or more sensor fault signals. Then, the method employs a dynamic controller to evaluate the signals corresponding to the sensor fault at least after a first fast fault signal, or a second slow fault signal. If the first fast fault signal is detected, the dynamic controller generates a signal for at least one of partially or completely temporarily switching off the at least one chassis actuator, while maintaining ESC in an active state. Conversely, if the second slow fault signal is detected, the dynamic controller generates a signal for temporarily switching off the ESC.

Abstract: A vehicle includes a steering wheel and at least one road wheel. The steering wheel is rotatably connected to a steering-wheel actuator, and the at least one road wheel is movably connected to a steering system. A controller is in communication with the steering system and the steering-wheel actuator. The controller is programmed to determine a steering-wheel angle based on a road-wheel angle, an operation mode, and a steering-compensation type; and to instruct the steering-wheel actuator to rotate the steering wheel according to the steering-wheel angle.
