The invention relates to an abnormal vehicle use detection method and device, a medium, equipment, a vehicle and a server. The method comprises the following steps: collecting user behavior data of a vehicle; calculating the collected user behavior data by applying an isolated forest algorithm; if the calculation result comprises the isolated abnormal point, judging that the vehicle is used abnormally. The user behavior data comprises one or more of the following data: whether a vehicle door is opened by a key, seat adjusting parameters, the pressure borne by a seat, the grip strength borne by a steering wheel, the change rate of the opening degree of an accelerator pedal, an air conditioner mode and voiceprint characteristics of a user. According to the scheme, whether the collected user behavior data is consistent with the corresponding data when the vehicle owner uses the vehicle or not is judged according to the abnormal points, so that whether the vehicle owner uses the vehicle or not is judged, namely, the vehicle is used abnormally. In this way, whether the vehicle is abnormally used or not is reversely verified through the user behavior, and when the vehicle is abnormally used, it can be quickly detected. The scheme is accurate in detection result and high in reliability.
本公开涉及一种异常用车检测方法和装置、介质、设备、车辆、服务器。所述方法包括:采集车辆的用户行为数据;对所采集的用户行为数据应用孤立森林算法进行计算;若计算结果包括被孤立的异常点,则判定所述车辆被异常使用。用户行为数据包括以下中的一者或多者:是否用钥匙开启车门、座椅调节参数、座椅承受的压力大小、方向盘所受握力大小、加速踏板开度的变化率、空调模式、用户的声纹特征。本方案根据异常点来判断采集的用户行为数据是否与车主用车时对应的数据一致,从而判断是否车主本人使用车辆,即异常用车。这样,通过用户行为来反向验证车辆是否被异常使用,当车辆被异常使用时,能够快速地被检测到。本方案的检测结果准确,可靠性高。
