The invention is suitable for the technical field of intelligent automobiles, and provides a method and device for determining the yaw rate of a vehicle, terminal equipment and a storage medium. The vehicle parameters comprise a road adhesion coefficient, the longitudinal speed of the vehicle, the actual longitudinal acceleration of the vehicle, the average steering angle of front wheels of the vehicle and the actual transverse acceleration of the vehicle; calculating a first candidate yaw rate of the vehicle based on the longitudinal vehicle speed, the actual longitudinal acceleration, the front wheel average steering angle and the road adhesion coefficient; determining a second candidate yaw rate of the vehicle based on the longitudinal vehicle speed, the actual lateral acceleration and the first candidate yaw rate; and determining a target yaw rate of the vehicle based on the first candidate yaw rate and the second candidate yaw rate. According to the method, the yaw rate of the vehicle under different emphasis is considered, the considered scene is more comprehensive, and the obtained target yaw rate is more accurate.
