Publication number: 20190004513Abstract: A control unit performs driving assistance. An acquiring unit acquires future circumstance information related to a future circumstance that an own vehicle is predicted to subsequently encounter on a route further ahead of a current location. A determining unit determines whether or not the future circumstance indicated by the acquired future circumstance information is applicable to an event in which continuation of driving assistance is not possible. An urgency level setting unit sets an urgency level that indicates a level of urgency of the future circumstance when the determining unit determines that continuation of driving assistance is not possible. A limit setting unit sets a limit related to time or distance at which to cancel driving assistance and switch to manual driving, based on the set urgency level. A notifying unit notifies a driver of information prompting cancellation of driving assistance based on content of the set limit.Type: ApplicationFiled: July 11, 2016Publication date: January 3, 2019Inventors: Kunihiko CHIBA, Hisashi IIDA, Minoru OKADA

Patent number: 8775051Abstract: An apparatus is used for diagnosing the temperature state of a catalyst converter. The catalyst converter includes a catalyst for cleaning an emission, and a conductive carrier for carrying the catalyst. The conductive carrier is energized for temperature rise of the catalyst, and the conductive carrier has a characteristic in which resistance drops with temperature increase. In the apparatus, a first obtaining unit obtains a first parameter having a first correlation with supply power to the conductive carrier for energization of the conductive carrier. A second obtaining unit obtains a second parameter having a second correlation with a temperature of the conductive carrier. A diagnosing unit diagnoses the temperature state of the conductive carrier based on a comparison between the first parameter and the second parameter.Type: GrantFiled: April 28, 2011Date of Patent: July 8, 2014Assignee: Denso CorporationInventors: Taro Hirai, Noriaki Ikemoto, Takeshi Harada, Naoyuki Kamiya, Hisashi Iida

Patent number: 8607552Abstract: In an emission control system, an absorbent in an exhaust-emission passage absorbs a particular component in the emission with a temperature thereof being lower than a first temperature, and desorbs therefrom the absorbed particular component with the temperature thereof being equal to or higher than the first temperature. A catalyst in the exhaust-emission passage converts the particular component desorbed from the absorbent into another component with a temperature thereof being equal to or higher than a second temperature higher than the first temperature. A heat recovery device is disposed in the exhaust-emission passage upstream of the absorbent and recovers heat from the exhaust emission by heat exchange between a heat-transfer medium and the exhaust emission. An adjusting unit adjusts an amount of heat to be recovered by the heat recovery device to thereby adjust a temperature state of the exhaust emission.Type: GrantFiled: October 12, 2010Date of Patent: December 17, 2013Assignee: Denso CorporationInventors: Noriaki Ikemoto, Tubasa Sakuishi, Hisashi Iida, Naoyuki Kamiya
