The invention discloses an overspeed alarm method based on an automobile instrument. The method adopts a mechanical or liquid crystal instrument for alarm display, and comprises the following steps: S1, acquiring speed limit information of a current road section in real time on a CAN network of a whole automobile; S2, comparing with the current actual vehicle speed, and judging the current overspeed state; S3, carrying out corresponding alarm display by controlling the pointer color of the mechanical or liquid crystal instrument according to whether the vehicle is overspeed or not; and S4, circulating the step S1-S4. The current road speed limit information is acquired and compared with the actual vehicle speed, and the pointer is controlled to present different colors so as to realize overspeed alarm.
本发明公开了一种基于汽车仪表的超速报警方法,采用机械或液晶仪表进行报警显示,包括以下步骤:S1.通过在整车的CAN网络上实时获取当前路段限速信息;S2.与当前实际车速做比较,判定当前超速与否的状态;S3.根据超速与否通过控制机械或液晶仪表的指针颜色以进行相应报警显示;S4.循环S1‑S4。通过获取当前道路限速信息与实际车速对比,并控制指针呈现不同颜色,以实现超速报警。
