Patent number: 11975730Abstract: A vehicle control apparatus executes a driving force limiting control when a mistaken operation condition is satisfied. The vehicle control apparatus determines that the mistaken operation condition is satisfied when a third condition is satisfied at a point in time when a second condition becomes satisfied, determines that the mistaken operation condition is not satisfied when the third condition is not satisfied at a point in time when the second condition becomes satisfied, the third condition becomes satisfied within a first time threshold since a first condition becomes satisfied, and a pressing condition is satisfied before the third condition becomes satisfied, and determines that the pressing condition is satisfied when an operation amount of an acceleration operator is greater than or equal to a positive second operation amount threshold, and an operation speed of the acceleration operator is greater than or equal to a positive second operation speed threshold.Type: GrantFiled: September 16, 2021Date of Patent: May 7, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Atsushi Takenaka, Takashi Unigame, Masaki Ikai

Patent number: 11962183Abstract: A backup power system according to the present disclosure includes a battery, a charging circuit, power storage, a first load, a second load, and a controller that controls the charging circuit. The controller causes an input current at the charging circuit to increase at a first rate of change in response to a start signal. When the controller detects an increase in a charging voltage at the power storage up to a first voltage at which driving of the first load is possible, the controller controls the charging circuit to cause the input current at the charging circuit to increase at a second rate of change lower than the first rate of change. The charging circuit is controlled by the controller to cause the input current to increase at the second rate of change, and the charging voltage at the power storage increases up to a second voltage at which driving of both the first load and the second load is possible.Type: GrantFiled: June 3, 2020Date of Patent: April 16, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Kazuo Takenaka, Takashi Higashide, Katsunori Atago, Youichi Kageyama, Hisao Hiragi, Yugo Setsu, Hiroki Nishinaka, Shinichi Tanida
