Method and apparatus for controlling steering of rear wheels, and vehicle and storage medium

An apparatus for controlling steering of a rear wheel, the apparatus comprising a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the processor is configured to, when executing the computer program:

• determine, 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;
• determine 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 front wheel, and a yaw direction value, wherein the yaw direction value is a numerical value indicating that a steering direction of the rear wheel is opposite to a steering direction of the front wheel when the steering wheel rotates towards a target direction;
• and
• control the steering of the rear wheel based on the target steering control quantity.

A vehicle, comprising:

• a memory;
• a processor;
• and
• a computer program stored in the memory and executable on the processor, wherein the processor, when executing the computer program, causes the vehicle to
• determine, 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;
• determine 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, wherein the yaw direction value is a numerical value indicating that a steering direction of the rear wheel is opposite to a steering direction of the front wheel when the steering wheel rotates towards a target direction;
• and
• control the steering of the rear wheel based on the target steering control quantity.
