Provided are an unmanned intelligent tracked high-clearance sprayer and a control method. A sprayer walking device comprises two tracked walking mechanisms driven by in-wheel motors. The tracked walking mechanisms at two sides are connected by a fixing rod. The top of each of the tracked walking mechanisms is provided with a sprayer raising/lowering mechanism. A spraying mechanism comprises an agricultural chemical mixing device and a spray boom device. Each tracked walking mechanism is provided with a trapezoidal support assembly therein. The agricultural chemical mixing device and a control device are arranged at an inner side of each of the trapezoidal support assemblies at both sides. The spray boom device is disposed at the sprayer raising/lowering mechanism and connected to the agricultural chemical mixing device, and is pulled with the sprayer raising/lowering mechanism to move up and down. The control device is respectively connected to the in-wheel motor, the sprayer raising/lowering mechanism, and the spraying mechanism. The wide-span spray boom of the invention is adjustable in a vertical direction, thereby meeting spraying requirements of various plants in different growth stages. Moreover, the invention can be remotely controlled without needing an operator, thereby reducing workload, and increasing a level of automation.La présente invention concerne un pulvérisateur enjambeur intelligent à chenilles sans pilote et un procédé de commande. Un dispositif de marche de pulvérisateur comprend deux mécanismes de marche à chenilles entraînés par des moteurs-roues. Les mécanismes de marche à chenilles sur deux côtés sont reliés par une tige de fixation. La partie supérieure de chacun des mécanismes de marche à chenilles est dotée d'un mécanisme d'élévation/abaissement de pulvérisateur. Un mécanisme de pulvérisation comprend un dispositif de mélange de produit chimique agricole et un dispositif de rampe de pulvérisation. Chaque mécanisme de marche à chenilles e
