Publication number: 20170264200Abstract: [Object] To reduce power consumption of a DC-DC converter. [Solution] A voltage conversion circuit includes a voltage generation unit, a stop control unit, a current supply unit, and an intermittent control unit. The voltage generation unit generates an output voltage on the basis of a current when the current is supplied. The stop control unit outputs a signal for stopping the supply of the current. The current supply unit supplies the current to the voltage generation unit until the signal is output. The intermittent control unit operates the stop control unit during a supply period of the current and stops the stop control unit when the signal is output.Type: ApplicationFiled: October 7, 2015Publication date: September 14, 2017Inventor: Takahiro Naito

Patent number: 9758172Abstract: A status determination apparatus determining a driver status in a movable body is provided. The status determination apparatus includes a behavior acquisition portion, a check portion, a determination portion, and a range change portion. The behavior acquisition portion obtains behavior information as present behavior information. The behavior information represents behavior of the movable body. The check portion collates the present behavior information with a threshold region representing a range of the behavior information at time when a driver drives absentmindedly. When the threshold region includes the present behavior information, the determination portion determines that the driver drives absentmindedly. The range change portion changes the threshold region.Type: GrantFiled: July 10, 2015Date of Patent: September 12, 2017Assignee: DENSO CORPORATIONInventors: Takahiro Naito, Katsuyoshi Nishii, Yoshinori Watanabe

Patent number: 8793060Abstract: A control apparatus controls an automatic stop of an engine mounted on a vehicle so as to automatically stop the engine if a predetermined stop condition is satisfied, the stop condition including a condition that a running speed of the vehicle is a prescribed speed or less. The control apparatus includes a prediction unit and a prohibition unit. The prediction unit predicts whether or not the next automatic stop time of the engine is less than a prescribed time capable of obtaining a fuel saving benefit based on a history of a vehicle stop time or an automatic stop time of the engine. The prohibition unit prohibits the next automatic stop of the engine if the prediction unit predicts that the next automatic stop time of the engine is less than the prescribed time.Type: GrantFiled: November 30, 2011Date of Patent: July 29, 2014Assignee: Denso CorporationInventors: Takayuki Takeuchi, Kenji Kawahara, Hiroshi Morimoto, Takahiro Naito, Takanori Sasaki
