CONTROL DEVICE, CONTROL METHOD, AND VEHICLE

An electronic control unit is a control device for controlling a vehicle including a vehicle speed sensor. The electronic control unit is configured to identify a section from start to stop of the vehicle using a vehicle speed detected by the vehicle speed sensor, determine whether the number of times of a low-speed section is more than a prescribed number of times, the low-speed section being the identified section where a representative value of the vehicle speed is less than a prescribed speed, and determine that the vehicle is in a specific situation where low-speed travel is inevitable, when it is determined that the number of times of the low-speed section is more than the prescribed number of times.
