Patent number: 9470554Abstract: A position detector includes a Hall element that detects a magnetic flux density and a temperature detection element that detects the temperature of the Hall element. In a rotation angle calculation process, a temperature correction value a is calculated by substituting a detection temperature t of the temperature detection element and a reference maximum voltage V0 at a reference temperature t0 for a=V0×k (t?t0). Next, a correction maximum voltage Vt is calculated by substituting the temperature correction value a for a temperature characteristic formula of Vt=V0+a. Further, a rotation angle ? of a magnet relative to the Hall element is calculated by substituting an output voltage VH of the Hall element and the correction maximum voltage Vt for ?=sin?1 (VH/Vt). Since the correction maximum voltage Vt is corrected according to the temperature, the rotation angle is accurately detected.Type: GrantFiled: July 29, 2013Date of Patent: October 18, 2016Assignee: DENSO CORPORATIONInventors: Takamitsu Kubota, Akitoshi Mizutani, Yoshiyuki Kono

Patent number: 9129067Abstract: In a position detector for detecting a position of a detection body, a signal processing circuit processes a signal outputted from a magnetic field detection element. A first storage circuit stores the signal outputted from the magnetic field detection element and outputs a signal to an external device through an output circuit in a normal operation mode. A second storage circuit stores an output value of the first storage circuit. When a malfunction determination circuit determines an instantaneous power interruption mode, a signal route changing circuit prevents a signal transmission between the first storage circuit and the second storage circuit and a signal transmission between the first storage circuit and the output circuit, prevents the second storage circuit from updating data for a certain period of time, and permits the second storage circuit in which updating is prevented to output a signal to the output circuit.Type: GrantFiled: November 21, 2012Date of Patent: September 8, 2015Assignee: DENSO CORPORATIONInventors: Takamitsu Kubota, Tohru Shimizu, Tetsuya Hara, Yoshiyuki Kono
