The invention provides a vehicle state detection method and device, a terminal, a program product and a transportation tool, and relates to the technical field of Internet of Vehicles. The vehicle state detection method comprises the following steps: acquiring a first speed of a vehicle; the three-axis acceleration of the space where an acceleration sensor of the vehicle is located is obtained, and filtering processing is conducted on the three-axis acceleration; calculating a composite vector according to the three-axis acceleration subjected to filtering processing; calculating a composite vector variance of a preset window length based on the composite vector; and determining the state of the vehicle according to the first speed and the composite vector variance. According to the embodiment of the invention, the accuracy of vehicle state detection can be greatly improved, and the equipment cost is effectively reduced. 本申请提供一种车辆状态的检测方法、装置、终端、程序产品和运输工具，涉及车联网技术领域。一种车辆状态的检测方法，包括：获取车辆的第一速度；获取所述车辆的加速度传感器所处空间的三轴加
