  • Patent number: 11654888
    Abstract: A control device of a vehicle that controls the vehicle capable of traveling according to a plurality of traveling modes including a first traveling mode and a second traveling mode. The control device includes a traveling mode control unit configured to cause the vehicle to travel according to any one of the plurality of traveling modes. The traveling mode control unit, when the traveling mode of the vehicle is set to the first traveling mode, shifts the traveling mode of the vehicle to the second traveling mode based on a detection result of a detection unit which detects an output of a power storage device and a transition threshold value. The traveling mode control unit includes a threshold value setting unit which changes a value of the transition threshold value in accordance with a maximum output of the power storage device.
