The invention discloses a wheel positioning parameter adjusting method and device, and relates to the technical field of vehicles, and the wheel positioning parameter adjusting method comprises the following steps: obtaining a comparison table of driving working conditions-execution mechanism arrangement points-optimal target hard point coordinates-optimal wheel positioning parameters through a preposed simulation test; determining an optimal target hard point coordinate and an optimal wheel positioning parameter corresponding to a current driving condition and an execution mechanism arrangement point by looking up a table; and controlling the execution mechanism to output an adjustment instruction to adjust the spatial position of the target hard point to the optimal target hard point coordinate, thereby indirectly adjusting the current wheel positioning parameter of the suspension system to the optimal wheel positioning parameter. According to the method, the wheel positioning parameters such as the actual camber angle, the toe-in angle, the kingpin camber angle and the kingpin caster angle can be continuously and actively adjusted in a targeted mode according to different driving working conditions, the flexibility is high, the adjusting range is large, and the driving stability of the whole vehicle can be improved.
