摘要： A control apparatus of power steering device having functions of monitoring intermediate troubles such as offset or drift out of signal troubles of torque sensor, and limiting the current for limiting the assist function is presented. In a control apparatus of power steering device for controlling a motor on the basis of a current control value calculated from a steering assist command value calculated by calculating means on the basis of a steering torque generated on a steering shaft, and a current value of a motor for applying a steering assist force to a steering mechanism, wherein the difference of a main torque signal and a sub torque signal of a torque sensor for detecting the steering torque is stored preliminarily, and the difference of the main torque signal and the sub torque signal during operation is compared with the stored value, and at least the current control value is limited when the difference based on the comparison is a condition larger than a first prescribed value and continues for a time longer than a first prescribed time.

摘要： A wall construction comprises block members or sections stacked vertically about five high and abutting horizontally to form a wall. Each block member or section comprises a top plate, bottom plate and two side studs. The block members are attached side by side by fastening plates on the top and bottom which overlap adjacent blocks, including one top fastening plate which overlaps the top plates of two adjacent blocks, and a bottom plate which overlaps the bottom plates of two adjacent blocks. The vertical components may be 2×4 dimensional wood pieces on the order of 15-20″ long, and the horizontal components about 30-40″ long. Steel studs may be used instead of wood pieces, and horizontal components may be up to eight feet long.

摘要： A control apparatus for an electrical power steering apparatus whereby a high output, small motor can be achieved, variation in the relative magnetization and coil positions and position detection precision requirements can be alleviated, steering feeling is improved, and apparatus cost is reduced. In a control apparatus for an electrical power steering apparatus for controlling a motor applying steering assistance force to a steering mechanism based on a current control value calculated from the current of a dc motor or brushless motor and a steering assistance control value calculated based on steering torque occurring at the steering shaft, torque ripple of the motor is suppressed to 10% or less.
