摘要： A motor control strategy for a motor in a front steering system for a vehicle that reduces vibrations from the motor being transferred to a vehicle hand-wheel. The control strategy also includes operating the electric motor in a commutation freeze mode if a position error signal is less than a first predetermined threshold by sending signals to coils of the motor to prevent to the motor from rotating, operating the electric motor in a commutation normal mode if the position error signal is greater than a second predetermined threshold that is greater than the first predetermined threshold, and operating the electric motor in an angle step mode if the position error signal is between an intermediate threshold and the second threshold where the angle step mode provides a signal to the motor to move the motor forward or backward a predetermined number of motor steps, one step at a time.

摘要： A method for controlling a limited by-wire active front steering system includes measuring an input steering angle, determining a tire saturation limit, and comparing the saturation limit to the input angle. A target actuator angle from a steering actuator is limited when the input angle is greater than the saturation limit. A constant value provides a fixed steering gear ratio when the input angle is less than the saturation limit. A limited by-wire steering system for a vehicle includes a steering device, a sensor for measuring an input steering angle, a controller for calculating a first target actuator angle when the input angle is less than a threshold, and a second target actuator angle when the input angle is greater than the threshold. The threshold is a calibrated saturation limit of a road wheel of the vehicle.

摘要： A method is provided for limiting a steering angle overlay applied by a steering actuator in a limited by-wire active front steering (AFS) system. The method includes determining a maximum rate limit for the steering angle overlay in order to minimize an undesired disturbance to the driver in the form of a torque and/or angle feedback while maximizing the rate of steering overlay allowed for a given set of vehicle operating conditions. The maximum rate limit is determined by a function of the input steering rate and braking level. A limited AFS system includes both steering and braking input devices, a steering actuator, and a controller having an algorithm. The controller uses the algorithm to calculate the maximum overlay rate limit and limits the steering actuator to the maximum overlay rate limit.
