摘要： PROBLEM TO BE SOLVED: To provide an absolute position detection device and an absolute position detection method capable of reducing a cost by using a member to be used for another purpose also for absolute position detection, and detecting the accurate absolute position of a steering wheel just after power supply. SOLUTION: This absolute position detection device is constituted from a second resolver 24 in a torque sensor for detecting a steering torque generated by rotation of a steering wheel, a motor resolver 41 for detecting a motor rotation angle of an electric motor driven corresponding to the rotation of the steering wheel, and an ECU 43 for operating and processing detection signals Rt, Rm outputted from each resolver 24, 41. In the ECU 43, the deviation (Rm-Rt) between the detection signals Rt, Rm from each resolver 24, 41 is divided by a standard deviation per rotation of the steering wheel, to thereby detect the absolute position of the steering wheel 18.

摘要： PROBLEM TO BE SOLVED: To prevent steering assistance independent of steering operation when a torque detection signal fluctuates by an effect of electromagnetic noise. SOLUTION: A signal line 85 is a transmission line of a reference signal sent from a torque sensor 6 toward an electronic control unit 7. The reference signal is an alternating voltage signal with a constantly constant peak value, and it is constantly sent from reference signal generating circuit 61 while an ignition switch of a vehicle is on. A microcomputer 71 constantly monitors a state of a signal inputted from the signal line 85, and it judges whether or not signal lines 81-85 are receiving electromagnetic noise on the basis of the signal state. When it is judged that the signal lines 81-85 are receiving electromagnetic noise, a fail safe process for preventing the steering assistance independent of the steering operation is carried out.

摘要： PROBLEM TO BE SOLVED: To provide a resolver by which the rotation angle of a shaft is detected with satisfactory accuracy over a wide range and which detects a torque acting on the shaft. SOLUTION: A resolver 20A and a resolver 20B are assembled respectively to both ends of a torsion bar in a state that one is turned by 90 deg.. The resolvers 20A, 20B are excited by an excitation signal at a definite amplitude from an excitation-signal generater 51, and they output one pair each of signals which are doubly amplitude-modulated at a small cycle and a large cycle when a rotor 31 and a rotor 41 are turned. A signal processing parts 52, 53 calculate rotation angles at 90 deg. each at the upper end and the lower end of the torsion bar as electrical angles changed over 0 to 360 deg.. A signal processing part 54 calculates the rotation angle of the torsion bar as a low-accuracy mechanical angle, it corrects the mechanical angle on the basis of the electrical angles, and it calculates the rotation angle over a wide range with satisfactory accuracy. A subtraction part 55 and an angle/torque conversion part 56 calculate the torque on the basis of the difference between both electrical angles.
