摘要：【中文】本发明涉及一种电动汽车高速公路智能充电方法及系统。该方法包括：判断电动汽车剩余的行驶里程是否大于剩余电量的行驶里程；若是，采集电动汽车信息、高速公路信息和充电站信息；根据电动汽车信息、高速公路信息和充电站信息，确定最短路径；根据最短路径，生成更新预定请求；判断是否出现更新事件；若是，则返回“获取电动汽车在高速公路上剩余的行驶里程和电动汽车的剩余电量的行驶里程”；若否，则将更新预定请求发送至充电站，确定充电站的预约队列；二次判断是否出现更新事件；若是，则调整预约队列；根据调整后的预约队列对电动汽车充电；若否，则根据预约队列对电动汽车充电。本发明能够使得电动汽车以总行驶时间最短到达最终目的地。 【EN】The invention relates to an intelligent charging method and system for an electric automobile highway. The method comprises the following steps: judging whether the remaining driving mileage of the electric automobile is larger than the driving mileage of the remaining electric quantity; if so, acquiring electric vehicle information, highway information and charging station information; determining the shortest path according to the electric vehicle information, the highway information and the charging station information; generating an updating preset request according to the shortest path; judging whether an updating event occurs or not; if yes, returning to the step of obtaining the travel distance of the electric automobile on the expressway and the travel distance of the remaining electric quantity of the electric automobile; if not, sending the updating reservation request to the charging station, and determining an appointment queue of the charging station; judging whether an updating event occurs for the second time; if yes, adjusting the reservation queue; charging the electric automobile according to the adjusted reservation queue; and if not, charging the electric automobile according to the reservation queue. The invention can ensure that the electric automobile can reach the final destination in the shortest total driving time.

摘要：【中文】本发明涉及一种汽车辅助变道系统及方法。本发明将IPS屏幕分别设置在左侧后视镜和右侧后视镜上，当驾驶员进行变道操作时，在IPS屏幕上分别显示侧后方最近的跟车距离信息以及距离等级指示灯，给予驾驶员最直观、清楚的提示信息，克服了只通过声音预警提醒车辆是否具备变道条件的单一性。并且本发明采用毫米波雷达测距系统进行跟车距离的测算，毫米波雷达测距系统具有较高的准确性，且灵敏程度高，提供的跟车距离信息更加准确，避免了声音预警辅助变道准确性低的问题，提高了驾驶的安全性，从而避免交通事故的发生。 【EN】The invention relates to an automobile auxiliary lane changing system and method. According to the invention, the IPS screens are respectively arranged on the left side rearview mirror and the right side rearview mirror, when a driver performs lane changing operation, the nearest following distance information and the nearest distance grade indicating lamp in the lateral rear part are respectively displayed on the IPS screens, the driver is given the most visual and clear prompt information, and the singleness that whether the lane changing condition is met or not is reminded only through voice early warning is overcome. The invention adopts the millimeter wave radar ranging system to measure and calculate the following distance, the millimeter wave radar ranging system has higher accuracy and high sensitivity, the provided following distance information is more accurate, the problem of low accuracy of auxiliary lane change by sound early warning is avoided, and the driving safety is improved, thereby avoiding traffic accidents.
