Steering control method and device for driverless car

The invention discloses a steering control method and device for a driverless car. One embodiment of the method comprises the following steps: current position of the driverless car is acquired in real time; the radius of curvature of a road turn in the current position is inquired in a high-precision map, wherein the radius of curvature is used for representing the value, larger than zero, of an arc radius at the road turn; in response to the inquired radius of curvature, the distance between front and rear axles of the driverless car and the length of the axles of the driverless car are acquired; steering angles of turning wheels of the driverless car are determined according to the distance between the front and rear axles and the length of the axles, and the steering wheels of the driverless car are controlled to steer at the steering angles. With adoption of the embodiment, the steering times of the driverless car are reduced, and the passenger riding experience of the driverless car is improved.
