The present invention discloses a vehicle load identification control method. The method comprises: signal collection and processing, output shaft rotating speed slope calculation, transmission outputtorque calculation, load factor calculation, load factor normalization processing, load factor filtering, target gear calculation, etc. A load identification function of a vehicle combines dynamics of the vehicle, an environmental condition and a road condition, utilizes automobile dynamics knowledges and utilizes the fuzzy control theory according to three input signals consisting of the size ofa driver stepping on the gas, the transmission output torque and the vehicle speed to identify the vehicle load, perform regulation of a shift reference vehicle speed on a ramp and calculate the optimal driving gear on the ramp.
