Patent number: 11731658Abstract: A vehicle control device or method controls an output of a drive source of a vehicle based on a color of an illuminated signal of a traffic light in a vehicle-advancing direction during travel in autonomous driving. The vehicle control device includes a control unit that estimates the color of the currently illuminated signal of the traffic light based on oncoming vehicle information and controls the output of the drive source based on an estimation result when the color of the illuminated signal of the traffic light cannot be acquired by the onboard camera. The control unit limits the output of the drive source and reduces a vehicle speed from a current vehicle speed to a vehicle speed at which fuel efficiency is superior to that at the current vehicle speed when the color of the illuminated signal of the traffic light is estimated to be red.Type: GrantFiled: December 5, 2017Date of Patent: August 22, 2023Assignee: Nissan Motor Co., Ltd.Inventor: Hirofumi Yano

Patent number: 11732862Abstract: An indicator lamp of the present invention includes a lamp body, a light source unit disposed inside the lamp body, and a light transmissive resin member disposed at a position for transmitting light that is emitted from the light source unit and for outputting the light from the lamp body. The light source unit emits red light having a maximum value of light intensity at a wavelength of 600 nm or longer and 700 nm or shorter. The light transmissive resin member has an L* value of 35 or less, a transmittance of light having a wavelength of 675 nm of 90% or greater and a total light transmittance of 5% or greater in the state in which an optical path length of transmitting light is 2 mm. This configuration provides an indicator lamp with excellent design that shows its presence by showing a red chromatic tone when a light source is turned on and that shows a black color tone when the light source is turned off.Type: GrantFiled: July 30, 2020Date of Patent: August 22, 2023Assignees: NISSAN MOTOR CO., LTD., MITSUBISHI CHEMICAL CORPORATIONInventors: Yu Sasaki, Tatsuomi Nakayama, Yusuke Hirata, Takao Marutani, Tadayoshi Sawada

Publication number: 20230261898Abstract: A CGW (7) connected to a first communication network (1) and a fifth communication network (5). The second communication network uses a communication protocol different from a communication protocol of the first communication network (1). The CGW (7) receives, from the first communication network (1), CAN frames each including a data field storing control information (CD) to be transmitted from the first communication network (1) to a second communication network (5), a CAN ID for identifying the control information (CD), and an error detection code (EC) stored in the data field and calculated on the basis of the control information (CD) and the CAN ID. The CGW (7) generates an FD frame including a data field storing the CAN frames and a CAN FD ID indicating that the CAN frames are stored in the data field, and transmits the generated FD frame to the fifth communication network (5).Type: ApplicationFiled: October 19, 2020Publication date: August 17, 2023Applicant: Nissan Motor Co., Ltd.Inventors: Kiyoshi Natori, Takashi Matsumoto

Patent number: 11724711Abstract: A vehicle idling stop control device has switches that detect an operation of opening a driver's door and an unbuckling of a driver's seat belt as disembarkation operations by a driver. When a disembarkation operation performed by the driver is detected during an idling stop, the idling stop is cancelled and the engine is restarted upon detecting a disembarkation operation performed by a driver during the idling stop. Also, restarting of the idling stop is prevented due to ending of the disembarkation operation performed by the driver until after the vehicle starts traveling. Thus, unnecessary automatic stopping and automatic restarting of the engine are thereby avoided when the vehicle sets off without the driver actually exiting the vehicle.Type: GrantFiled: January 21, 2020Date of Patent: August 15, 2023Assignee: Nissan Motor Co., Ltd.Inventor: Toshihiko Ootsuka
