摘要： A method for determining the center position of a steering wheel for a vehicle equipped with electric power steering having a brushless motor. Vehicle operating conditions corresponding to a straight direction of vehicle travel are detected. An estimated center position of the brushless motor is determined while the vehicle operating conditions are detected. A range of angular positions about the estimated center position is established in which the actual center position of the steering wheel is determined to be the position of the brushless motor equal to a midpoint of the range of angular positions.

摘要： A control steered angle calculation unit includes: an end position determination unit that determines whether a rack shaft is located at either one of right and left rack end positions; a motor absolute angle calculation unit that detects a motor absolute angle; an end position-corresponding motor angle setting unit that, when the rack shaft is determined to be located at either one of the right and left rack end positions, sets the detected motor absolute angle as an end position-corresponding motor angle corresponding to the one of the right and left rack end positions; and a control steered angle origin setting unit that calculates an average value of right and left end position-corresponding motor angles as an offset angle, and sets an angle obtained by subtracting the offset angle from the detected motor absolute angle as an origin of the control steered angle represented by the motor ab solute angle.

摘要： In an electric power steering device assisted by a brushless motor, an induced voltage from a brushless motor is detected when a main power supply is off. The motor is determined to be in a high rpm state when the induced voltage is in a first transient state from a voltage ≦a high rpm detection threshold Th1 to a voltage≧Th1, thereby setting an intermittent excitation cycle of a revolution angle sensor connected to the motor to a short cycle. The motor is determined to be in a low rpm state when the induced voltage becomes a voltage≧a high rpm detection threshold Th2 after a wait period corresponding to an electrical angle between peaks or valleys of an output voltage has elapsed in a second transient state from a voltage–Th1 to a voltage≧Th2, thereby setting the cycle to a long cycle.

摘要： An electric power assisted steering apparatus comprising a combined angular position and torque sensor assembly comprising an upper column shaft that in use is operatively connected to a steering wheel of the vehicle, a lower column shaft that in use is operatively connected to the road wheels of the vehicle, a torsion bar that interconnects the upper column shaft and the lower column shaft, a first and a second torque signal generating means that each generate a first torque signal based on angular deflection of the torsion bar, an absolute position signal generating means that in use produces an absolute upper column position signal indicative of the angular position of the upper column shaft, an electric motor that is connected to the lower column shaft of the torque sensor assembly, and a motor position sensor carried by the motor that provides a motor position signal dependent on the angular position of the motor rotor. The apparatus further comprises a virtual torque signal generating means that in use is adapted to determine a third torque signal from a combination of the motor position signal and the absolute angular position signal produced by the processing means.
