The present invention relates to the technical field of automobiles, in particular to a new gear switching strategy for an automatic transmission. This set of gear shifting system is mainly composed of a knob-type electronic shifter, an SCU (electronic shifter control module), a DCT transmission and a TCU (transmission control module). The signals of all systems are interacted by a CAN bus. The gear shifting strategy is as follows: when a driver puts a vehicle into an R/D gear, and the SCU performs judgment after receiving the gear shifting request from the driver, wherein the judging condition at this time is that if the vehicle speed or brake does not meet the set requirements, the SCU will lock the knob of the shifter and prohibit putting into the R/D gear, thus effectively preventing the shifter end from shifting into the R gear at higher forward speed or shifting into the D gear at higher reverse speed. More intelligent functions can be supported, such as advanced auxiliary driving functions such as automatic parking and adaptive cruise.
