The invention is suitable for the technical field of automobiles, and provides a wheel tread pattern detection method and device, a vehicle-mounted terminal and a vehicle. The method comprises the steps that motion information of the vehicle in a set time period is acquired; according to the motion information, the actual rolling radius of wheels of the vehicle is obtained through calculation; and determining a tread pattern detection result of the wheel according to the actual rolling radius and the standard rolling radius. Compared with the prior art, the method has the advantages that whether the tread is worn or not can be determined according to the actual rolling radius and the standard rolling radius of the wheel of the vehicle, so that an accurate tread detection result is obtained, and the tire detection accuracy is improved. 本申请适用于汽车技术领域，提供了一种车轮的胎纹检测方法、装置、车载终端及车辆，所述方法包括：获取车辆在设定时间段内的运动信息；根据运动信息，计算得到车辆的车轮的实际滚动半径；根据实际滚动半径和标准滚动半径，确定车轮的胎纹检测结果。与现有技术相比，本方法可以根据车辆的车轮的实际滚动半径和标准滚动半径，确定胎纹是否磨损，从而得到准确的胎纹检测结果，提高了对
