Abstract

The embodiment of the invention discloses an analog simulation method and device of a four-wheel steering system and a computer storage medium, and belongs to the technical field of analog simulation. The method comprises the steps that a steering rack part is created in a whole vehicle model of an automobile through an ADASM application program, a four-wheel steering system model is built in an Amesim application program, the whole vehicle model is built according to the solid structure of the automobile, and the steering rack part is used for controlling the steering of rear wheels of the automobile; according to the steering rack part, the whole vehicle model and the four-wheel steering system model are associated in the Amesim application program; and analog simulation is performed on the four-wheel steering system of the automobile according to the whole automobile model and the four-wheel steering system model. According to the embodiment of the invention, the ADASM application program and the Amesim application program are used for jointly simulating the four-wheel steering system of the automobile, and the steering rack part for controlling the steering of the rear wheels is arranged in the whole automobile model, so that the simulation reliability of the four-wheel steering system is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of simulation, and in particular to a simulation method, device and computer storage medium of a four-wheel steering system. Background technique [0002] Four-wheel steering means that during the steering process of the car, the four wheels can simultaneously deflect relative to the body according to signals such as the front wheels or driving speed. The rear wheels of a four-wheel steering vehicle can deflect in the same direction as the front wheels, and can also deflect in the opposite direction. When the front wheels and rear wheels deflect in the same direction, the stability and safety of the vehicle at high speed can be improved; When deflecting, the turning diameter of the vehicle can be reduced, making the passing performance of the vehicle better. It can be seen that the four-wheel steering system of a car has a greater impact on the performance of the car. Therefore,...
