Telecontrol target vehicle is often used for developing, experimenting, inspection and training of air to ground and ground to ground equipments, generally travels along a special straight orbit, in order to shorten accelerating time, increase the flexibility and reliability of governing speed in limited length and speedup in a short time. This paper attempts to show a kind of implementation of stepless shift gears control for the telecontrol target vehicle system. Firstly, structure, function and principle of system are given. Then, hardware implementation of the modules is given in detail, including measure device of velocity and controller of the gun. Lastly, the software flow is introduced about the realization of stepless shift gears by using singlechip. The target practice showed that functions have been finished for automation shift gears in finite distance and speedup in the shortest time, and this method can reduce the system cost, increase the system agility and reliability.
