Gear shifting strategy adjusting method and related device

The invention provides a gear shifting strategy adjusting method and device, a readable storage medium, a gearbox controller and a vehicle, and belongs to the field of vehicles. The method comprises the steps that different types of gear shifting strategies are preset, in the actual driving process of a driver, the number of acceleration intentions within a period of time is subjected to statistics, and then classified statistics is conducted on the acceleration intentions, for example, the acceleration intentions are divided into rapid acceleration, common acceleration, slow acceleration and the like; and the proportions of various statistic acceleration intentions are taken as weighted values, and the corresponding gear shifting strategies are multiplied by the weighted values, and then are added together to obtain a self-adaptive gear shifting strategy. Due to the fact that the obtained self-adaptive gear shifting strategy takes the acceleration intention of the driver in the period of time as the referenc
