The invention relates to a driving simulation test method in the field of a power system of an electric automobile. In the method, a speed curve part, a power calculating and matching part, a data processing part, a dynamometer, a vehicle road impedance realization part, an accelerator output part, a brake output part, a shift operation part and the power system are combined, and the corresponding functional modules are integrated; by setting target speed-time parameters, technical parameters of different vehicles and the like and calculating and matching the power of the whole vehicle, different commands such as rotating speed, torque, accelerator, brake, clutch, shift and the like at different speeds are obtained, and components on a test bench of the power system of the electric automobile perform corresponding actions so as to complete driving simulation tests under different predetermined road conditions and different vehicle models; and analysis can be performed according to the acquired and recorded related data after the tests are finished so as to obtain the related performance analysis report of the power system and complete the driver driving simulation test on the test bench of the power system of the electric automobile.
