The invention discloses a vehicle semi-physical simulation system based on angle input. The vehicle semi-physical simulation system comprises a driver operation module, an angle sensor, a data processing card and an xPC simulation system. The driver operation module comprises a steering wheel and a seat. The angle sensor is arranged on the steering wheel and used for acquiring the angle signal of the steering wheel. The data processing card is used for preprocessing the received angle signal and then transmitting the preprocessed angle signal to the xPC simulation system. The xPC simulation system is used for performing simulation by combining a preset vehicle model and a control strategy according to the preprocessed angle signal. Compared with pure software simulation, simulation is more accurate because of access of the physical hardware, and vehicle parameter adjustment is convenient so that the vehicle semi-physical simulation system has the advantages of being low in input, convenient to construct, low in cost, easy to maintain and expand and great in real-time performance.
