摘要： PROBLEM TO BE SOLVED: To provide an angle detection apparatus which can achieve detection output required by an electronic control unit or the like without performing fine adjustment of an installation angle when being installed in an apparatus to be detected.
SOLUTION: With the angle detection apparatus installed in the apparatus to be detected such as a throttle valve of an internal combustion engine, the apparatus to be detected is operated to obtain a detection lower limit value Vmin and an output upper limit value Vmax by the angle detection apparatus. An offset correction amount is determined from the differences between a desired detection lower limit value V1 and a desired detection upper limit value V2 required by the electronic control unit or the like and the detection lower limit value Vmin and the output upper limit value Vmax. Offset amount adjustment is performed on the output of the angle detection apparatus by an output adjustment section. As a result, the detection output required by the electronic control unit can be achieved at all times without performing the adjustment of the installation angle of the angle detection apparatus.
