FIELD: vehicles.
SUBSTANCE: in the all-wheel drive intelligent control method, vehicle state information is obtained, including the speed of the front and rear wheels of the vehicle; an estimated output torque based on the vehicle state information is calculated; the vehicle friction disc temperature based on the front wheel speed, the rear wheel speed, and the estimated output torque is calculated. The calculated output torque is corrected according to the calculated friction disc temperature to obtain the actual output torque, and the friction clutch is controlled to generate the actual output torque.
EFFECT: improved reliability of the temperature measurement of the friction disc.
