The invention is convenient for the handwriting signing operation of the user, and the signing information has higher safety.

摘要：【中文】本发明公开了一种无信号灯路口车辆安全通行方法，该方法包括：目标车辆到达预设无信号灯路口预设电子区域时，在搜索确定目标区域范围内无其他车辆或其他车辆不会与目标车辆发生碰撞危险时，提示目标车辆正常通行，当存在碰撞危险时，根据车辆驶入路口情况分别制定通行策略并执行通行信息提示，保障目标车辆安全、顺利通过该无信号灯路口，同时为通过该路口的其他车辆提供安全保障。本发明无信号灯路口车辆安全通行方法，保障了目标车辆行驶和其他车辆行驶安全的同时，大大提高了无信号灯路口的通行效率。 【EN】The invention discloses a safe passing method of vehicles at a signal lamp-free intersection, which comprises the following steps: when a target vehicle reaches a preset electronic area of a preset signal-lamp-free intersection, when no other vehicle exists in the range of the target area or the collision danger between the other vehicle and the target vehicle does not occur, the target vehicle is prompted to normally pass, when the collision danger exists, a passing strategy is respectively formulated according to the condition that the vehicle enters the intersection, and the passing information prompt is executed, so that the target vehicle is ensured to safely and smoothly pass through the signal-lamp-free intersection, and meanwhile, the safety guarantee is provided for the other vehicles passing through the intersection. The method for safely passing the vehicles at the signal lamp-free intersection ensures the running safety of the target vehicle and other vehicles and greatly improves the passing efficiency of the signal lamp-free intersection.

摘要：【中文】本发明公开了一种车辆定位数据上传方法和车载终端，方法包括：实时采集车辆状态并以一定的采样频率获取车辆的定位坐标，作为原始记录坐标；将预设时间间隔内的原始记录坐标按车辆状态对应的时间点进行分段归集；判断各归集点列中原始记录坐标的有效性，确定各归集点列中的有效定位点；计算车辆运动状态下各归集点列的有效定位点按照预设上传时间间隔上传时的最大上传量，选择最大上传量对应的有效定位点作为第一上传定位点并上传；根据车辆静止状态下各归集点列的有效定位点计算确定一个第二上传定位点并上传。本发明保障了上传有效定位点的准确和高效，并针对上传的车辆定位点之间的缺失进行计算补传，提高了车辆行驶定位数据的完整性。 【EN】The invention discloses a vehicle positioning data uploading method and a vehicle-mounted terminal, wherein the method comprises the following steps: acquiring the state of a vehicle in real time, and acquiring the positioning coordinate of the vehicle at a certain sampling frequency to be used as an original recording coordinate; carrying out segmented collection on the original recorded coordinates in a preset time interval according to time points corresponding to the vehicle states; judging the effectiveness of the original recorded coordinates in each aggregation point row, and determining effective positioning points in each aggregation point row; calculating the maximum uploading amount of the effective positioning points of the collection point rows in the moving state of the vehicle when the effective positioning points are uploaded according to a preset uploading time interval, and selecting the effective positioning point corresponding to the maximum uploading amount as a first uploading positioning point and uploading the first uploading positioning point; and calculating and determining a second uploading positioning point according to the effective positioning points of the aggregation point rows in the static state of the vehicle and uploading.
