摘要： 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.

摘要： A method for operating an active steering system of a vehicle, in which a ratio between a wheel steer angle and a steering wheel angle specified by the driver can be modified by superimposition of a superimposition angle. The method comprises detecting an offset between a requested motor angle and an actual motor angle, and reducing the offset between the requested motor angle and the actual motor angle using a reduction rate that is selected as a function of at least one input variable specified by the driver.

摘要： 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).

摘要： Methods, apparatus, systems and articles of manufacture are disclosed to improve electronic power assisted steering in a vehicle. An example apparatus includes memory and a processor to execute instructions to determine a steering column torque associated with a steering column of an electronic power assisted steering (EPAS) system in a vehicle, determine a steering column torque derivative based on a derivative of the steering column torque, determine a compliance compensation torque based on the steering column torque and the steering column torque derivative, and adjust a steering response of the steering column based on the compliance compensation torque.

摘要： A method for assisting entry or exit of a motor vehicle into and from a parking space. The motor vehicle equipped with a steering wheel and at least one steering servomotor capable of applying a steering angle steered wheels of the motor vehicle. A control unit actuates the steering servomotor for carrying out an automatic parking process, in which case, during the parking process there is no mechanical connection between the steering wheel and the steered wheels and the steering wheel does not move.

摘要： A method for estimating steering assistance provided by a power steering system of a vehicle may include correlating an internal torque applied by an adaptive steering system of the vehicle with an external torque applied to a steering assembly of the vehicle. The method may also include estimating the steering assistance based on the correlation.

摘要： A vehicle includes an engine configured to auto stop and auto start. The vehicle includes an active front steering system with an electric actuator. A controller operates the electric actuator at a current limit that is less than a requested current of the electric actuator in response to a request to change a steering ratio by an amount that results in the requested current being greater than the current limit during an engine auto stop event. The current limit may decrease from the requested current to a predetermined limit after transitioning to the engine auto stop event. The current limit may increase from the predetermined limit to the requested current after transitioning from the engine auto stop event.

摘要： A vehicle including an active front steer system including a locking mechanism having a solenoid actuated locking pin and a spring for biasing the pin toward an extended or locked position for engaging a locking disc of the active front steer system wherein the active front steer system further includes a current sensor for sensing the motion of the pin of the solenoid when the engine of the vehicle is shut down and pulse width modulated current to the solenoid is reduced and when the pin movement is sensed, the pulse width modulated current is increased (fed forward duty cycle) to reduce the movement of the pin to reduce the noise made when the metal pin makes when contacting the metal locking disc. The end of the pin and/or the locking disc may also include an insulating material to further reduce any remaining noise made when the metal pin makes when contacting the metal locking disc.
