The invention relates to an automatic speed limiting system of an electric vehicle, and the system comprises a button element function module, a Kjeldahl speed limiter module, a small GPS radar module, a single chip microcomputer module, a Hall sensor module, a voice function module and an electric vehicle control module. When the system is in use, the button element function module starts the Kjeldahl speed limiter module, the Kjeldahl speed limiter module transmits information through the small GPS radar module, required speed signals are provided by the Hall sensor module, speed calculationis conducted through the collected speed signals to obtain a speed value V, the speed value V is compared with the set maximum speed: if V is greater than Vm, the electric vehicle is in an overspeedstate, and the system sends an early warning voice to remind a driver of reducing the speed; the speed limiter is wide in application range and high in operability, can be used for controlling violation of the electric vehicle in traffic to reduce traffic accidents, and can enable a driver of the electric vehicle to develop a good traffic driving habit, so that the driver can consciously abide bytraffic rules.
本发明涉及电动车自动限速系统,包括按钮元件功能模块、凯琴限速器模块、小型GPS雷达模块、单片机模块、霍尔传感器模块、语音功能模块和电动车控制模块,使用时,按钮元件功能模块,启动凯琴限速器模块,凯琴限速器模块通过小型GPS雷达模块的传输信息、所需要的速度信号由霍尔传感器模块来提供,通过采集到的速度信号来进行速度计算得出一个速度值V,并于设置的最大速度进行比较,若V>Vm,则电动车速度处在超速状态,系统则发出预警语音来提醒驾驶者进行减速措施,限速器的应用范围广,可操作性强,能够用来控制电动车在交通中出现的违规现象,来减少交通事故,限速器可以使得电动车驾驶着养成良好的交通行驶习惯,以便自觉的遵守交通规则。
