Zusammenfassung: | The invention belongs to the technical field of automatic driving, and discloses a vehicle braking control method, device and equipment and a storage medium. The method comprises the following steps: acquiring a vehicle tire image collected by a vehicle-mounted camera; comparing the vehicle tire image with the initial tire image to obtain a tire wear condition; obtaining a tire adhesion coefficient according to the tire wear condition and the adhesion coefficient graph; and determining a brake control strategy according to the tire adhesion coefficient. Different tire wear degrees are monitored, a preset tire maximum executable deceleration mapping relation model is searched according to the tire wear degrees, and finally when a tire adhesion coefficient is smaller than a first threshold value, the intervention opportunity of an AEB function is controlled by calculating a needed braking distance. The maximum executable deceleration of the vehicle is estimated according to the tire wear condition, the vehicle |
