The invention discloses a gear self-learning method and device based on electronic gear shifting, a vehicle and a medium. The method comprises the steps that when a whole vehicle is offline, gear shifting driving force output by a gear shifting actuator controller according to a target gear calibration instruction is received; wherein the target gear calibration instruction comprises a parking gear calibration instruction and a non-parking gear calibration instruction; an initial self-learning position is determined according to the gear shifting driving force and a theoretical angle difference value corresponding to the target gear calibration instruction, and a to-be-selected gear position located at a balance force point in a current swing path is determined with the initial self-learning position as a starting point; and the theoretical gear range of the target gear of the current vehicle is determined according to the target tolerance value of the current vehicle, and the to-be-selected gear position mee
