Publication number: 20210380167Abstract: A driving supporter includes a support inhibitor that inhibits support of driving when a steering-operation value is greater than a threshold value. The support inhibitor includes a threshold-value determiner that determines the threshold value to a value greater when a first object and a second object are present than when the first object is present, and the second object is absent. The first object has a relationship in which a relative positional relationship between the object and an own vehicle is a relationship in which a steering operation is estimated to be performed in a first direction in which the own vehicle avoids the object. The second object has a relationship in which the relative positional relationship is a relationship in which the steering operation is estimated to be performed in a second direction reverse to the first direction such that the own vehicle avoids the object.Type: ApplicationFiled: August 25, 2021Publication date: December 9, 2021Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Hiroaki KATAOKA, Taisuke HASEGAWA

Patent number: 9834213Abstract: A lane keeping assist apparatus is disclosed which includes a lane detecting part; an information output device; an actuator that generates a force for changing an orientation of a vehicle; and a controller that performs a lane keeping assist control based on a positional relationship between the lane and the vehicle, wherein the lane keeping assist control includes an alert control and an intervention control via the actuator, the controller selectively operates in a first mode where the alert control and the intervention control are executable, a second mode where only the intervention control is suppressed or a third mode where the alert control and the intervention control are suppressed, and the controller, during operating in the first mode, performs a mode transition to the second mode when the abnormality determination results indicate an abnormal state concerning only the part related to the intervention control.Type: GrantFiled: July 1, 2014Date of Patent: December 5, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuji Okuda, Hidenobu Kinugasa, Taisuke Hasegawa

Publication number: 20160176400Abstract: In a state where steering required torque is outputted (S1: YES), the steering required torque is canceled (S12) based on the fact that a state of driver torque being inputted has continued (S11: YES). A cancellation delay time, which represents the length of time from when the driver torque is inputted until the steering required torque is canceled, is set to be shorter when the driver torque is higher than or equal to a timer-ON threshold 2 than when the driver torque is between a timer-ON threshold 1 and the timer-ON threshold 2. Consequently, in the case where a steering wheel is quickly turned by a driver and thus high torque is inputted to the steering wheel, control torque will be canceled in a short time and thus steering will be performed in quick response to the steering wheel operation of the driver. As a result, an uncomfortable feeling caused to the driver will be suppressed.Type: ApplicationFiled: July 23, 2014Publication date: June 23, 2016Inventors: Takahito Nakano, Taisuke Hasegawa, Hidenobu Kinugasa

Patent number: 8536342Abstract: Disclosed is a process for producing a thiabenzoazulene-propionic acid derivative which is useful as an active ingredient of an antihistaminic agent or the like. According to the producing process of the present invention, it is possible to produce a thiabenzoazulene-propionic acid derivative where the 2-position of the thiabenzoazulene skeleton is substituted with propionic acid. The thiabenzoazulene propionic-acid derivative thus synthesized has excellent antagonistic action to histamine H1 receptor and low intracerebral transmigration and, therefore, is useful as an active ingredient of the pharmaceutical composition such as an antihistaminic agent.Type: GrantFiled: July 26, 2010Date of Patent: September 17, 2013Assignee: Nippon Zoki Pharmaceutical Co., Ltd.Inventors: Kunihiko Higashiura, Taizo Ito, Takashi Ogino, Taisuke Hasegawa
