The invention discloses a trailer connection identification method, a storage medium and a vehicle. A vehicle is connected with a lighting system of a trailer through a trailer wire harness connector, the lighting system comprises a plurality of trailer lamps, and the method comprises the steps that the working current of each trailer lamp is detected in sequence; according to the working current range of the working current of each trailer lamp and a first corresponding relation, determining an open circuit diagnosis parameter value of each trailer lamp, the first corresponding relation including a corresponding relation between the working current range and the open circuit diagnosis parameter value; the open circuit diagnosis parameter value is used for determining whether a line between the corresponding trailer lamp and the vehicle is open; according to the working current of each trailer lamp and the open circuit diagnosis parameter value of each trailer lamp, determining whether the line between each trailer lamp and the vehicle is open; and when it is determined that the lines corresponding to at least two trailer lamps in the multiple trailer lamps are not open, it is determined that the vehicle is connected with the trailer. The method improves the accuracy of identifying whether the trailer is connected or not.
一种拖车连接的识别方法、存储介质及车辆。车辆通过拖车线束连接器与拖车的灯光系统连接,灯光系统中包括多个拖车车灯,该方法包括:依次检测每个所述拖车车灯的工作电流;根据每个拖车车灯的工作电流所处的工作电流范围,以及第一对应关系,确定每个拖车车灯的开路诊断参数值,第一对应关系包括工作电流范围与开路诊断参数值的对应关系,开路诊断参数值用于确定对应的拖车车灯与车辆之间的线路是否开路;根据各拖车车灯的工作电流,以及各拖车车灯的开路诊断参数值,确定各拖车车灯与车辆之间的线路是否开路;当确定多个拖车车灯中,至少存在两个拖车车灯对应的线路未开路时,确定车辆与拖车连接。该方法提升了识别拖车是否连接时的准确性。
