摘要： A method, system, and apparatus for providing enhanced steering pull compensation are provided. The method compensates for steering pull in a vehicle steering system that includes a handwheel. The method includes monitoring the vehicle to determine whether the vehicle is heading forward along a substantially linear straight-ahead path and, if so, measuring handwheel torque, as a sensed torque signal, to determine an amount of steering pull existing at the handwheel. The method also includes generating a torque assist signal in response to the sensed torque signal and calculating an offset signal for reducing the amount of steering pull to substantially zero. The method further includes producing a modified torque assist signal by adding the offset signal to the torque assist signal, and applying the modified torque assist signal to the vehicle steering system.

摘要： An electric power steering system includes a steering wheel, an electric assist motor operatively coupled to the steering wheel, and an electronic controller operatively coupled to the assist motor. A steering wheel position sensor provides an output indicative of an angular position of the steering wheel. A motor position sensor provides an output indicative of a relative angular position for the motor. Steering wheel position sensor output is acquired at each of a plurality of angular positions of the motor, thereby establishing a set of points defining a curvilinear relationship between steering wheel sensor output and motor position sensor output. The set of points is sampled to calculate a straight line which approximates the curvilinear relationship, thereby reducing periodic errors in the steering wheel sensor output. The straight line is employed to determine a position offset for the motor position sensor output corresponding to a system zero position. The system zero position is a position for which the vehicle will travel along a linear, substantially straight-ahead path.

摘要： A pulse width modulation system provides for enhanced output resolution through software control. The pulse width modulation control system normally has a control period during which the pulse width modulation state assumes a predetermined one of a plurality of output states. The method herein toggles between two adjacent output states during any single control period to effectuate a resultant system response characteristic of a system having a greater number of available output states. Furthermore, certain preferred implementations may also suppress undesirable harmonic excitation of the system through quasi-random toggling.

摘要： An electric power steering system of a vehicle includes a controller for controlling an electric motor connected to a steering column or other steering mechanism. The velocity of the motor must be determined to maintain the proper current to the motor. A method of estimating the velocity includes obtaining a first and second velocity signals from one or more sensors monitoring the motor. The first and second signals have different characteristics, e.g., the first signal may have a higher resolution than the second signal. An acceleration (or deceleration) of the velocity of the electric motor is computed based on the different representations of the velocity supplied by the different signals. An estimate of the velocity of the motor is then determined based on the acceleration/deceleration and the different representations of the velocity. The electric current provided to the electric motor is then adjusted based on the estimated velocity to meet the desired motor output (i.e., motor torque and velocity).
