The all-terrain comprises a frame, a parameter detection module and a gear control module. The frame is provided with a unique gear shifting key. The shift key generates a gear shift signal when effectively pressed. The parameter detection module is used for detecting gear switching parameters related to gear shifting operation in the all-terrain vehicle. The gear control module receives the gear switching signal and the gear switching parameter and automatically switches between different gears according to different gear switching parameters when receiving the gear switching signal. By integrating one shift key, the cost of the all-terrain vehicle is reduced, and the risk that a plurality of shift keys are easy to touch by mistake can be reduced. Meanwhile, the gear control module realizes automatic gear switching operation by combining gear switching signals and different gear switching parameters, and control logic is simpler.
