Abstract
PURPOSE: To prevent errors regarding operation and the slippage, etc. of reference locations, by forming the output signals of each sensor of angle-end-revolution reference in rectangular wave-forms and by counting logic, and by using the rise and fall of the rectangular waves by means of an angle sensor as angular positions and the reference position.
CONSTITUTION: When a crank-shaft of an internal combustion engine turns, wave- forms b are generated at an angle sensor 4, and when a magnet 2 at the reference location faces to a revolution reference sensor 5 wave-forms a are put out from the sensor 5, thus changing these wave-forms into rectangular wave pulses c, d by means of each wave-form shaping circuit 8, 6 for reference and angles. When the logic of these pulses is counted by means of a NAND71 to produce output e and a R-SFF is set through a differentiation circuit in the fall and reset in the fall of the pulses c, the reference location is put out in the rise of the pulses e and changed into pulses f, and positioned at the center of angular locations, thus the crank-shaft does not alter to the positional slippage of the pulses c. Consequently, rotary locations can accurately be detected.
