摘要： [Problem] An object of the present invention is to provide an electric power steering apparatus for calculating a front-wheel estimated steering angle based on right and left front wheel speeds, calculating a rear-wheel estimated steering angle based on right and left rear wheel speeds, calculating a 4-wheel estimated steering angle by using the front-wheel estimated steering angle and the rear-wheel estimated steering angle, and correcting a probability of the 4-wheel estimated steering angle or correcting an output of a control with the 4-wheel estimated steering angle by using the front-wheel estimated steering angle, the rear-wheel estimated steering angle and 4 wheel speeds, thereby preventing an irregular output. [Means for Solving] The present invention is an electric power steering apparatus which has a steering torque sensor to detect a steering torque, a current command value calculating section to calculate a current command value based on the steering torque, a motor to apply an assist torque, and a motor driving control section to drive and control the motor, comprises: a control function with an input steering angle; and a steering angle estimating/calculating section to calculate a front-wheel estimated steering angle and a rear-wheel estimated steering angle based on a 4 wheel speeds and calculate a 4-wheel estimated steering angle, wherein the 4-wheel estimated steering angle is used for a steering angle control.

摘要： The present invention relates to a double analysis of signals emitted by a rotational angle sensor. For this purpose, the signal emitted by the rotational angle sensor is processed in a first signal path with respect to a maximum angle quality of the angle signal to be calculated. A second signal path for processing the signal emitted by the rotational angle sensor is optimized to indicate a maximum diagnosability of errors.

摘要： A rotational position sensing device for sensing rotation of an axially adjustable shaft of a shaft and arm assembly of a door that does not require readjustment after the shaft and arm assembly are adjusted includes a fixed bracket supporting a post, a position sensor having an upper portion, a lower portion and an extended portion, and a rotating portion. The extended portion extends from the upper portion of the position sensor and constrains the post of the bracket such that the upper portion of the position sensor is unable to axially rotate relative to the bracket. The rotating section is adapted to be fixed to the shaft and engage with the lower portion of the position sensor, such that the rotating portion rotates relative to the upper portion of the position sensor.

摘要： A batteryless absolute encoder determines the accuracy of absolute position information to be output therefrom when electric power is turned on and outputs an alarm signal in the case of abnormality. The batteryless absolute encoder includes an absolute position computing section 6, an absolute position storing section 7, and a determining section 8. The absolute position computing section 6 computes the absolute position of a spindle to be detected, including the number of revolutions of the spindle, on the basis of detection signals output from four reluctance resolvers RS0 to RS3. The absolute position storing section 7 includes a non-volatile memory for storing the absolute position output from the absolute position computing section 6 when electric power is turned off. The determining section 8 compares an absolute position output from the absolute position computing section 6 when electric power is turned on and the absolute position stored in the non-volatile memory and outputs an alarm signal if a difference between the two absolute positions is larger than a predetermined value.
