Patent number: 10214215Abstract: An emergency vehicle control device, when an emergency vehicle stop switch is operated for an operation time threshold value or longer in a state where automatic vehicle stop control is not executed, determines that the automatic vehicle stop control is intended to be executed. Later, when the interval between the previous operation and the current operation of the emergency vehicle stop switch is within an operation interval threshold value, the determination that the automatic vehicle stop control is intended to be executed is sustained, whereas when the interval exceeds the operation interval threshold value and the emergency vehicle stop switch is operated for the operation time threshold value or longer, it is determined that the execution of the automatic vehicle stop control is intended to be cancelled.Type: GrantFiled: July 8, 2016Date of Patent: February 26, 2019Assignee: HONDA MOTOR CO., LTD.Inventors: Masayuki Nakatsuka, Kei Oshida, Makoto Katayama, Yukinori Kurahashi

Publication number: 20180086338Abstract: When a host vehicle makes a lane change from a first lane into a second lane, an approach suppression control unit of a travel assist device monitors whether or not another vehicle, which is traveling in a third lane existing on an opposite side from the first lane with the second lane interposed therebetween, is making a lane change into the second lane. In the case it is determined that the other vehicle is making a lane change from the third lane into the second lane, the approach suppression control unit implements an approach suppression control for suppressing the host vehicle and the other vehicle from approaching each other.Type: ApplicationFiled: September 15, 2017Publication date: March 29, 2018Inventors: Hiroyuki Yamada, Makoto Katayama, Hiroyuki Koibuchi, Haruhiko Nishiguchi, Satoshi Fujii, Daiki Haratake, Yoshifumi Banno

Patent number: 8226372Abstract: A compressor includes a motor driven by a controller and having a rotor and a stator, a compressing unit driven by the motor in a hermetic container in which refrigerant is filled. Driving the motor at a low rpm, the controller practices a feedback control which determines a timing of turning on/off switching elements based on a signal detecting a position of the rotor, and when the motor is driven at a high rpm, the controller practices an open-loop control which outputs a given frequency and drives the motor synchronizing with the given frequency. This structure achieves a compressor working with a fewer noises in PWM driving.Type: GrantFiled: March 16, 2004Date of Patent: July 24, 2012Assignee: Panasonic CorporationInventors: Koji Hamaoka, Hidetoshi Nishihara, Katsumi Endo, Makoto Katayama, Shuichi Yakushi, Tatsuyuki Iizuka, Yuji Saiki, Hidehisa Tanaka, Tomonori Ouchiyama
