Patent number: 7885757Abstract: There is provided a dither control means that performs a dither control, which compulsively changes an air-fuel ratio alternately to rich side and to lean side by increasing and decreasing fuel injection quantity of an injector (fuel injection valve) in a stepped manner. A predicted value (ideal A/F value ID), which indicates an ideal change of a detection value of an A/F sensor (oxygen concentration sensor) in a case where the A/F sensor is not degraded, is set as a standard value. Then, an integral of a difference between the detection value of the A/F sensor, which changes in accordance with the dither control, and the standard value is calculated. If a calculated value of the integral is larger than a predetermined value, it is determined that the A/F sensor is degraded.Type: GrantFiled: April 1, 2009Date of Patent: February 8, 2011Assignee: Denso CorporationInventor: Masahiko Yamaguchi

Publication number: 20100269805Abstract: A switching element is connected between a heater of an oxygen sensor and a ground in series. A voltage sensing resistor is connected in parallel with the switching element and in series with the heater. When the switching element is in a de-energization state, if the heater degrades and a resistance of the heater changes, a heater terminal voltage (potential at middle point between heater and voltage sensing resistor) changes correspondingly. Therefore, when the switching element is in the de-energization state, a heater terminal voltage determination parameter changing in accordance with the heater terminal voltage is sensed, and a degradation determination value corresponding to a battery voltage and temperature of the heater is calculated from a map. The heater terminal voltage determination parameter is compared with the degradation determination value to determine whether the heater has degraded.Type: ApplicationFiled: April 23, 2010Publication date: October 28, 2010Applicant: DENSO CORPORATIONInventors: Hiroyuki FUKUDA, Masahiko Yamaguchi, Tetsuji Mitsuda

Patent number: 7677227Abstract: An opening of a waste gate vale is adjusted to control an actual supercharging pressure of intake air. Abnormality in a changing characteristic of the actual supercharging pressure relative to a change in a TCV control duty value can be detected. When an engine is in a steady operation condition, the TCV control duty value is forcibly changed repeatedly by a predetermined amount from 0% to 100%. A deviation between a target supercharging pressure corresponding to the TCV control duty value and an actual supercharging pressure is calculated each time the TCV control duty value is changed by the predetermined amount. This deviation is compared with an abnormality determination value to determine presence/absence of the abnormality in the changing characteristic of the actual supercharging pressure relative to the change in the TCV control duty value.Type: GrantFiled: July 3, 2006Date of Patent: March 16, 2010Assignee: DENSO CorporationInventors: Yasuo Sagisaka, Yasuo Mukai, Masahiko Yamaguchi, Kuniaki Ueda
