[0060] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0061] The present invention provides a gear shift control method for a loader gearbox, which includes: acquiring an automatic gear shift signal for the loader to automatically switch from a current gear to a requested gear; and acquiring the loader's current gear and current speed according to the loader's current gear. Turbine speed; the torque converter speed ratio is obtained according to the engine speed and the turbine speed, and the torque converter speed ratio is compared with a first numerical interval. If the torque converter speed ratio is higher than the first numerical interval, then Perform one-shift compensation on the requested gear; if the torque converter speed ratio is lower than the first numerical range, perform one-shift compe...
