The invention discloses a gear shifting method based on the braking working condition of a two-gear AMT pure electric vehicle, which comprises the following steps of: 1, a brake pedal is stepped, and a vehicle is braked; 2, a braking mode is judged, if the braking mode is a regenerative braking mode or an electro-hydraulic composite braking mode, the third step is executed, and if the braking mode is hydraulic independent braking, the step 6 is executed; 3, front and back braking force and electro-hydraulic braking force are distributed, if the braking force is hydraulic independent braking force, the step 6 is executed, and if not, the step 4 is executed; 4, a gear shifting decision is made, if gear shifting is carried out, the step 5 is carried out, and if not, the step 7 is carried out; 5, gear shifting operation is conducted and acts on an automobile body; 6, the hydraulic braking model is executed and acted on the automobile body; and 7, the driving motor model is executed and acted on the automobile body.

    本发明公开了一种基于两挡AMT纯电动汽车制动工况的换挡方法,包括以下步骤:步骤一:踩下制动踏板,汽车进行制动;步骤二:进行制动模式判断,若为再生制动或者电液复合制动模式则进入步骤三,若为液压单独制动则进入步骤六;步骤三:进行前后制动力与电液制动力的分配,若为液压单独制动力则进入步骤六,若否则进入步骤四;步骤四:进行换挡决策,若进行换挡则进入步骤五,若否进入步骤七;步骤五:进行换挡操作并作用于汽车本体;步骤六:执行液压制动模型并作用于汽车本体;步骤七:执行驱动电机模型并作用于汽车本体。
