    Abstract: A main detection element detects a physical quantity that changes according to a rotation of a detection target. A sub detection element detects a physical quantity that changes according to the rotation of the detection target. A signal processing unit outputs main rotation information that is information corresponding to a detection value of the main detection element and sub rotation information that is information corresponding to a detection value of the sub detection element. A package seals the main detection element, the sub detection element, and the signal processing unit. Centers of all the main and the sub detection elements are arranged at positions shifted from a detection center of the detection target. The main detection element is arranged at a position closer to the detection center than the sub detection element. The package is arranged at a position where a center of the package deviates from the detection center.

    Abstract: An extent of decrease in analysis accuracy caused by splitting a source code can be reduced. An influence identifying unit identifies, for each of two functions included in a source code as a target, influence degrees exerted over analysis of the source code when the two target functions are each split into separate split codes, as analysis influence degrees between the two target functions, from an information amount passed between the two target functions. A splitting unit splits the source code into a plurality of split codes such that a sum of the analysis influence degrees between the functions each being split into the separate split codes decreases.

The sensor units include magnetic field detection elements for detecting a rotation of a motor, and output mechanical angles related to the rotation angle in one rotation and count values related to the number of rotations of the motor, respectively. One rotation of the motor is divided into indefinite regions, in which detection deviation of the count values may occur, and definite regions, in which no detection deviation occurs. The definite region of the count value is set to deviate from the definite region of the other count value. Absolute angle calculation units calculate the absolute angles using the count values of the definite regions.

  • Patent number: 10501121
    Abstract: A rotation angle detector includes a voltage detector receiving a supply of voltage from a first power source and detecting a motor rotation regarding a motor, the motor rotation more specifically detected as (i) a rotation angle of the motor and (ii) a number of rotations of the motor. Also, a second power source is disposed separately from the first power source and supplying voltage to the voltage detector. Thus, even when the voltage of the in-vehicle battery lowers or the voltage supply therefrom is interrupted, the voltage supply to a voltage detector is continuous from the power storage device, thereby enabling a continuous detection of the rotation angle and the rotation number of the motor.
