The invention discloses a vehicle multi-sensor information fusion method and system based on rear wheel steering, and relates to the technical field of sensor information processing. The vehicle multi-sensor information fusion method based on rear wheel steering comprises the following steps: data acquisition; evaluating influence conditions; vehicle state adjustment; and information fusion. According to the method, the inertia condition interference coefficient, the position state interference coefficient and the mileage state interference coefficient are obtained through the obtained multi-sensor data, whether the vehicle state is adjusted or not is judged, and finally the inertia condition interference coefficient, the position state interference coefficient and the mileage state interference coefficient after the vehicle state is adjusted are obtained. And information fusion is carried out to obtain the vehicle three-dimensional speed model, so that the effect of improving the accuracy of multi-sensor information fusion based on the rear-wheel steering vehicle is achieved, and the problem of low accuracy of multi-sensor information fusion based on the rear-wheel steering vehicle in the prior art is solved.
