Abstract

The invention provides a steering control method and device and an automobile. The steering control method is applied to a vehicle comprising a power-assisted steering device. The steering control method comprises the following steps: acquiring the current vehicle speed and steering wheel rotation data of the vehicle; calculating a theoretical steering ratio and a limited steering ratio corresponding to the current vehicle speed and steering wheel rotation data according to the current vehicle speed and steering wheel rotation data; determining an actual steering ratio according to the theoretical steering ratio and a limited steering ratio; outputting a steering ratio output control instruction to the power-assisted steering device according to the actual steering ratio. According to the embodiment of the invention, under the condition that the conventional power-assisted system is not changed, namely under the condition that driving habits are not changed, the steering angle input by rotating the steering wheel by a driver is adjusted according to the vehicle speed and steering wheel rotation data, so that a small steering angle can be output under the conditions that the steering wheel is swerved at a high speed and the like, and the driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a steering control method, device and automobile. Background technique [0002] In the existing steering assist system, after the driver controls the steering wheel, the steering assist system will provide assistance for steering according to the rotation angle and the like. However, in some cases, for example, in a critical situation, the driver tends to instinctively slam the steering wheel. In this case, slamming the steering wheel at high speed is prone to turning and pushing the head or overturning accidents. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a steering control method, device and automobile, which are used to change the input steering wheel steering angle through the speed change device of the steering assist device according to the vehicle speed and steering wheel rotation da...
