The invention relates to a speed limitation control method and particularly relates to an AMT (automated manual transmission) speed limitation control method. The AMT speed limitation control method comprises the following steps: 1), a car body controller receives a speed limitation signal and a car state signal sent by a speed limitation switch and a state signal, and transmits the received speed limitation signal and the received car state signal to a transmission controller through a car communication module; 2), the transmission controller receives the speed limitation signal and the car state signal, and determines a speed limitation scheme according to a car speed calculation formula, rotation speed of an engine and gear of a transmission; 3), the transmission controller realizes a speed limitation function according to the speed limitation scheme obtained in the step 2). The AMT speed limitation control method is used for realizing the speed limitation function through a speed limitation control method of controlling the gear of the transmission or limiting highest rotation speed of the engine through a message or limiting the gear of the transmission and meanwhile controlling the rotation speed of the engine through the car communication module, so that economical efficiency of a whole car can be improved, great significance is realized for limiting relatively high speed, and a speed limitation effect is good.
