The invention relates to the technical field of automobile control, and discloses an anti-skid control method, device and equipment and a storage medium. When the road surface risk judgment coefficient is greater than or equal to a slip coefficient threshold value and/or the change rate of the acceleration is greater than or equal to a first acceleration change threshold value, determining that the vehicle has a potential slip trend; when the vehicle has a potential slip trend, a torque adjustment slope is obtained according to the road surface risk judgment coefficient or the change rate of the acceleration; and determining an execution torque according to the torque adjustment slope, and sending the execution torque to a motor controller. According to the method, the potential slip trend is judged through the road surface risk judgment coefficient or the change rate of the acceleration, early-stage intervention control is carried out when the potential slip trend exists, torque can be effectively reduced before ASR/TCS intervention, and the driving smoothness and safe control are improved.
