Method for controlling electrically driven four-wheel-drive vehicle, and device for controlling electrically driven four-wheel-drive vehicle

A control method controls an electric four-wheel-drive vehicle to switch a drive torque distribution between a first distribution prioritizing energy efficiency and a second distribution prioritizing driving performance. The distribution is set to the second distribution where wheel slip is detected during a trip, and returned to the first distribution once the vehicle has stopped. When wheel slip is detected at least during acceleration, the distribution is switched from the first distribution to the second distribution. When wheel slip is detected during deceleration, a slip experience flag is set. The slip experience flag is maintained at least until starting off in a subsequent trip. Where the slip experience flag has been set, the distribution is maintained as the second distribution when the vehicle has stopped, and where the slip experience flag has not been set, the distribution is returned to the first distribution upon the vehicle being stopped.
