Beschreibung
Zusammenfassung:	A real-time four-wheel drive control method, comprising: determining working modes of a real-time four-wheel drive system according to vehicle state recognition and vehicle mode selection; determining, according to vehicle modes and driver operation information, feedforward torques corresponding to different working modes of the four-wheel drive system; performing closed-loop feedback control according to a yaw rate deviation and a front-rear axle slip of a vehicle, and calculating a feedback torque that meets the operation stability and traction requirements of the vehicle; and calculating a torque upper limit of the real-time four-wheel drive system according to the working modes of the real-time four-wheel drive system, a vehicle working state, and an ESP instruction, so that the safety of the real-time four-wheel drive system and the stability of the vehicle are ensured. The real-time four-wheel drive control method can improve the traction performance, safety, economy and operation stability of the vehic
