The embodiment of the invention relates to the field of vehicle detection, in particular to a tire looseness detection method and device and a storage medium. The method comprises the following steps: acquiring a mechanical characteristic quantity of the tire at a target moment; the target moment is the moment when the fastener moves to a target position, and the target position is located below the center of a tire; the mechanical characteristic quantity comprises a tire vertical force, a tire transverse force and a tire longitudinal force of the tire; acquiring the wheel speed of the tire at the target moment; the loosening characteristic quantity of the fastener at the target moment is determined based on the wheel speed and the mechanical characteristic quantity of the tire, the loosening characteristic quantity comprises the target force of the fastener and the target torque of the fastener, the target force of the fastener is the vertical force of the fastener, and the target torque of the fastener is the vertical force of the fastener. The target torque of the fastener is a torque of a longitudinal force of the fastener.

    本公开实施例涉及车辆检测领域,更具体地,涉及轮胎松动的检测方法及装置、存储介质。所述方法包括:获取所述轮胎在目标时刻的力学特征量;所述目标时刻是所述紧固件运动至目标位置的时刻,所述目标位置位于轮胎中心下方;所述力学特征量包括所述轮胎的轮胎垂向力、轮胎横向力以及轮胎纵向力;获取所述轮胎在所述目标时刻的轮速;基于所述轮速以及所述轮胎的力学特征量确定所述紧固件在所述目标时刻的松动特征量,其中,所述松动特征量包括所述紧固件的目标力和所述紧固件的目标力矩,所述紧固件的目标力是所述紧固件的垂向力,所述紧固件的目标力矩是所述紧固件的纵向力的力矩。
