Abstract

Provided are a method and apparatus for controlling steering of a rear wheel, a vehicle, and a storage medium. The method for controlling the steering of the rear wheel includes: determining, in response to a fault occurring in a front-wheel steering-by-wire system of a vehicle, a steering control quantity of a steering wheel in the vehicle; determining a target steering control quantity for the rear wheel in the vehicle based on the steering control quantity, a target steering ratio between the steering wheel and a front wheel, and a yaw direction value; and controlling the steering of the rear wheel based on the target steering control quantity. Since yaw is generated due to steering of the front wheel, the yaw direction value is introduced when determining the target steering control quantity, enabling the steering with the rear wheel to produce the same steering effect as the steering with the front wheel. Therefore, when the fault occurs in the front-wheel steering-by-wire system, the method can not only assist the vehicle in performing steering through the rear wheel, but also provide the same steering effect as the front wheel, which is in line with a steering habit of a vehicle user.
