Patent number: 11498617Abstract: A vehicle control method for controlling a vehicle using a vehicle control apparatus includes: a sensor configured to detect a state outside a subject vehicle; and a control device. The vehicle control method includes: executing control of recovering a travel trajectory of the subject vehicle to a target trajectory, as ordinary control, by giving a steering amount in a lateral direction with respect to a travel lane of the subject vehicle; using detection data of the sensor to determine whether or not another vehicle is traveling in an adjacent lane to the travel lane of the subject vehicle; and when determining that the other vehicle is traveling in the adjacent lane ahead of the subject vehicle, increasing a response of the steering amount to a higher response than that in the ordinary control, before the subject vehicle passes the other vehicle.Type: GrantFiled: October 11, 2021Date of Patent: November 15, 2022Assignee: Nissan Motor Co., Ltd.Inventors: Yuta Akamatsu, Masahiro Kobayashi, Yasuhisa Taira, Osamu Fukata, Ko Sato

Patent number: 11046333Abstract: A drive-assisted vehicle control device includes a controller that controls travel of a host vehicle. During travel on a curved route, the controller establishes a threshold value established as a boundary value for suppressing acceleration of the host vehicle. The threshold value is lower when another vehicle is present on an outside-peripheral-side curved route adjacent to a host-vehicle travel lane than when another vehicle is not present on the outside-peripheral-side curved route. The controller determines whether a lateral acceleration is greater than the threshold value during travel on a curved route. The controller permits accelerating travel on the curved route upon determining that the lateral acceleration is less than or equal to the threshold value, but suppresses accelerating travel on the curved route when upon determining that the lateral acceleration is greater than the threshold value.Type: GrantFiled: August 24, 2017Date of Patent: June 29, 2021Assignee: Nissan Motor Co., Ltd.Inventors: Yuta Akamatsu, Masahiro Kobayashi, Yasuhisa Taira, Osamu Fukata

Patent number: 10928428Abstract: The present invention aims to reduce the leakage current that flows when measuring a high voltage and includes: a voltage detector that detects a voltage and outputs a detection voltage; a current supplier that supplies a measurement current across a pair of input terminals via a protective resistor; and a processor that executes a voltage measurement process, which measures the voltage based on data indicating the detection voltage, and a resistance measurement process, which measures a resistance connected between the input terminals based on the voltage and the current. A first switch is connected in parallel to the protective resistor and the processor executes the voltage measurement process in a state where the first switch has been set open to measure the terminal voltage, and executes the resistance measurement process by setting the first switch shorted when the voltage is equal to or below the reference voltage value.Type: GrantFiled: January 11, 2019Date of Patent: February 23, 2021Assignee: HIOKI DENKI KABUSHIKI KAISHAInventors: Tetsuya Nakamura, Takashi Hirao, Yuta Akamatsu, Yuta Suzuki
