Patent number: 9869656Abstract: In an impedance detector, a current application portion applies a first current and a second current, directions of which are opposite to each other, to an element of an oxygen concentration sensor. A detection portion detects a difference between a current application prior voltage and a current application subsequent voltage. The current application prior voltage is a voltage between both of ends of the element before being applied with the first current, and the current application subsequent voltage is a voltage between both of the ends of the element when being applied with the first current. An impedance calculation portion calculates an impedance of the element based on the difference detected by the detection portion and a value of the first current. The current application portion is configured to change a current application time to apply the first current and the second current according to a command provided thereto.Type: GrantFiled: March 26, 2015Date of Patent: January 16, 2018Assignee: DENSO CORPORATIONInventor: Shinya Uemura
