The invention provides a vehicle speed control method and system based on battery residual electric quantity, and the method comprises the steps: collecting the electric quantity data of a vehicle battery, and carrying out the filtering of the electric quantity data, and obtaining the filtering data; performing analog-to-digital conversion on the filtering data to obtain coded data; adding a check code to the coded data to obtain to-be-transmitted data; transmitting the to-be-transmitted data to a controller for verification, and obtaining a residual electric quantity value of the vehicle battery; controlling the vehicle speed according to the residual electric quantity value of the vehicle battery; the problem that the electric quantity display of an instrument is unstable and inaccurate in the riding or climbing process of an electric vehicle is solved; and the problem of excessive loss caused by large-current discharge of the battery when the electric vehicle is in a low-electric-quantity riding state is solved.

    本发明提供了一种基于电池剩余电量的车速控制方法及系统,包括:采集车辆电池的电量数据,对电量数据进行滤波,得到滤波数据;对滤波数据进行模数转换,得到编码数据;对编码数据添加校验码,得到待传输数据;将待传输数据传输至控制器进行校验,得到车辆电池的剩余电量值;根据车辆电池的剩余电量值,对车速进行控制;本发明解决了电动车在骑行或爬坡过程中仪表电量显示不稳定、不精准的问题;以及电动车在低电量骑行状态下电池进行大电流放电,造成过度损耗的问题。
