Patent number: 11654887Abstract: A hybrid vehicle control method for a hybrid vehicle is provided for a drive system including an internal combustion engine, a generator that is driven by the internal combustion engine, and a battery that is charged with electric power generated by the generator. A target power generated by the generator is set and the target engine output is calculated for the internal combustion engine according to the target generated power. The air density in the environment in which the vehicle travels is detected. The target engine output is corrected based on the detected air density with respect to the decrease in air density, and the generated power of the generator is made to follow the target generated power. The execution of air density correction is permitted or stopped depending on an operating state of the drive system.Type: GrantFiled: April 16, 2019Date of Patent: May 23, 2023Assignee: Nissan Motor Co., Ltd.Inventor: Hidekatsu Akiyama

Patent number: 11652241Abstract: A method for manufacturing a battery has a stacking step in which a plurality of unit cells are stacked, the unit cells being such that a positive electrode obtained by a positive electrode active material layer containing an electrolytic solution disposed on a positive electrode current collector, and a negative electrode obtained by a negative electrode active material layer containing an electrolytic solution disposed on a negative electrode current collector with a separator interposed therebetween. In the stacking step, each time one of the unit cells is stacked, the stack of the unit cells are pressed from the stacking direction.Type: GrantFiled: March 26, 2019Date of Patent: May 16, 2023Assignee: Nissan Motor Co., Ltd.Inventors: Tomohiro Kaburagi, Hajime Satou, Kazuyuki Yoda, Shigeo Watanabe, Yusuke Mizuno, Yusuke Emori, Takuya Sakurai

Patent number: 11648960Abstract: A control method and a control device are provided for autonomously controlling a host vehicle when turning across an oncoming lane at an intersection with a signal light being green. A determination is made as to whether or not the host vehicle can make a right or left turn while a signal light is still green at a time of the right or left turn, either while the host vehicle in the left lane is waiting in a row of vehicles to make the right turn or while the host vehicle traveling in the right lane is waiting in a row of vehicles to make the left turn at an intersection during travel under autonomous driving. The host vehicle then creeps forward to a start position for starting at a next time the signal light is green upon determining the right or left turn cannot be made.Type: GrantFiled: January 25, 2018Date of Patent: May 16, 2023Assignee: Nissan Motor Co., Ltd.Inventor: Hajime Miura
