Publication number: 20230030288Abstract: A control device is used in a subject vehicle capable of performing autonomous driving with no obligation for a driver to monitor periphery. The control device determines whether a permission state, in which a specific act other than driving is permitted to the driver, is continued or not when approach of an emergency vehicle to the subject vehicle is detected during an autonomous cruising period in which the autonomous driving is being performed. The control device restricts display of a content provided to the driver when the permission state of the specific act is determined to be not continued.Type: ApplicationFiled: October 11, 2022Publication date: February 2, 2023Inventors: Yuuta MATSUMOTO, Kunihiko CHIBA, Kazuki KOJIMA, Shiori MANEYAMA, Yukari ITOU

Patent number: 11566704Abstract: A shift selector device includes an input member, a position setting mechanism and an activation controller. A selection operation of selecting a shift position is input to the input member. The position setting mechanism defines a movable range of the input member while supporting the input member in a displaceable manner. A plurality of the shift positions and at least one activation position linked to an automated travel system are disposed in the movable range. When the activation position is selected by displacement of the input member, the activation controller outputs an activation instruction for instructing a control function of the automated travel system linked to the activation position to be activated.Type: GrantFiled: May 31, 2019Date of Patent: January 31, 2023Assignee: DENSO CORPORATIONInventor: Kunihiko Chiba

Publication number: 20230019934Abstract: A presentation control apparatus is configured to control information presentation to a driver of a vehicle capable of performing automated driving. The presentation control apparatus includes a judging section and a presentation control section. The judging section is configured to distinguish between a particular action permitted state where the driver is permitted to take a particular action other than driving during the automated driving, a particular action prohibited state where the driver is prohibited to take the particular action during the automated driving, and an automated driving prohibited state where the automated driving is prohibited.Type: ApplicationFiled: September 28, 2022Publication date: January 19, 2023Inventors: Takuya KUME, Yuuta MATSUMOTO, Kunihiko CHIBA, Kazuki KOJIMA, Shiori MANEYAMA

Publication number: 20230013492Abstract: When transitioning from both prohibition state that prohibit a specific action and a hand release during an execution of the autonomous driving to a specific action permission state that permits a driver to execute a specific action other than a driving operation, a presentation control device presents information indicating that the transition is allowable prior to information indicating that the transition is executed. When transitioning from a hand release permission state that prohibits the specific action and permits hand release from a steering wheel to the specific action permission state, the presentation control device presents the information indicating that the transition is allowable and the information indicating that the transition is executed at a same time.Type: ApplicationFiled: September 16, 2022Publication date: January 19, 2023Inventors: Takuya KUME, Yuuta MATSUMOTO, Kunihiko CHIBA, Kazuki KOJIMA, Shiori MANEYAMA

Patent number: 11256935Abstract: A recognition unit recognizes a specific sign in a captured image acquired by an image acquisition unit. A first notification processing unit displays a specific captured image as a captured image showing the specific sign on a display device in a vehicle.
