The invention relates to the field of vehicle travelling control, in particular to a transmission gear shifting control method. The vehicle transmission gear shifting control method for enhancing heating comprises the steps that the initial gear shifting speed V is set to be equal to f(+/-x), wherein V is the gear shifting speed of the x gear; the following choices are made according to the heating state of a vehicle, (1) when a vehicle heater is turned on, the current gear shifting speed V of the vehicle is made to be equal to f(+/-x)*K, wherein K is the acceleration coefficient of the x gear and is larger than 1 and no larger than 1.3; and (2) when the vehicle heater is turned off, the current gear shifting speed V of the vehicle is made to be equal to V; and the vehicle gear is controlled through the current gear shifting speed V of the vehicle during travelling of the vehicle. By adoption of the vehicle transmission gear shifting control method for enhancing heating, balance between the dynamic property, the comfort, the economy and the driveability is comprehensively considered according to user personalization and driving state requirements, and in the heating state, the heating performance of the vehicle is improved by increasing the gear shifting speed and decreasing the ignition advance angle, accordingly a user is more comfortable, and the driveability of the vehicle is improved.
