Patent number: 11628744Abstract: A vehicle control device includes a main control device, a sub-control device, and a temperature detection unit. The main control device includes a recognition unit that recognizes a peripheral situation of a vehicle, a driving control unit that controls steering and acceleration/deceleration of the vehicle independently from an operation of a driver, and a mode determination unit that determines a driving mode of the vehicle. The sub-control device is capable of controlling the vehicle in place of the main control device. The temperature detection unit detects a temperature of a second battery that is different from a first battery supplying power to the main control device and supplies power to the sub-control device. The mode determination unit changes the driving mode of the vehicle from the second driving mode to the first driving mode when a temperature of the second battery is lower than a predetermined temperature.Type: GrantFiled: December 21, 2021Date of Patent: April 18, 2023Assignee: HONDA MOTOR CO., LTD.Inventors: Hayahito Ukai, Takashi Tsujioka, Takehiro Horigome
