The invention discloses a sliding friction point self-learning method and device, electronic equipment and a medium, and relates to the technical field of automotive electronics, in the vehicle driving process, whether a vehicle is in a neutral sliding state or not is monitored based on the running parameter value of the vehicle; when the vehicle enters the neutral sliding state, whether a preset self-learning enabling condition is met or not is judged; if the judgment result is that the self-learning enabling condition is met, speed reduction processing is conducted on an input shaft of the vehicle, and the rotating speed of the input shaft is monitored; if it is monitored that the rotating speed of the input shaft is not higher than a preset first rotating speed threshold value, input shaft speed reduction processing is stopped, a clutch is controlled to be engaged at a preset target speed, and the position of the clutch is monitored; and determining a new position of a sliding friction point according to the position of the clutch and the rotating speed of the input shaft, and updating the current position of the sliding friction point according to the obtained new position of the sliding friction point. According to the method, the gear shifting quality of the vehicle can be improved, and the gear shifting stability of the vehicle is improved.
