Claim 2:
3. The method for dual-motor control on an electric vehicle based on adaptive dynamic programming according to claim 2, wherein S2 specifically comprises:
S21) conducting torque distribution for the two motors based on the total torque that is required by the two motors of the electric vehicle under different driving conditions and calculated in S1, which can be expressed by the following formula:

Te=Te1+Te2  (2), wherein

Te1 and Te2 denote output torque of the two motors of the electric vehicle, respectively;
S22) establishing the execution network and the evaluation network for the electric vehicle, and conducting offline training on the execution network and the evaluation network based on the data information of the electric vehicle obtained in S1;
S23) establishing a minimum energy consumption function for a high-efficiency operating point of the two motors of the electric vehicle to minimize energy consumption of dual-motor operation of the electric vehicle, thereby obtaining a data set of high-efficiency dual-motor operation of the electric vehicle under different driving conditions, which can be expressed by the following formula:

minAIM=α(P1−PTe1)+β(P2−PTe2)  (3), wherein

P1 and P2 denote drive system output power of the two motors, PTe1 and PTe2 denote actual output power of the two motors, α and β denote weighting coefficients, α and β are proportional to rated power of the two motors, and α+β=1; and
S24) establishing the efficiency MAP database of the dual-motor high-efficiency operating area of the electric vehicle, and generating a controller signal based on the data set of high-efficiency dual-motor operation obtained in S23.
