Abstract: In this paper, the automatic gear control system of the wire-controlled chassis of target vehicle is studied, the traditional manual gear control mechanism is transformed to having the ability of automatic gear shifting control. In mechanical structure, a set of gear shifting mechanism is designed, which can realize gear shifting by controlling two push rod motors in X direction and Y direction. In control, a special gear controller is developed, which can control the forward and reverse rotation of the two-way motor and accurately control the stroke distance, and has the gear feedback function to realize closed-loop control. In the control software, a complete set of control logic is designed. By sending specific gear control instructions to the gear controller, the gear control of the target vehicle's drive-by-wire chassis can be realized.
