The invention discloses a vehicle state determination method and device, equipment, a medium and a product. The method comprises the following steps: acquiring driving data of a target vehicle, wherein the driving data comprises a longitudinal speed, a front wheel steering angle and inertial navigation system IMU data; determining the lateral speed of the target vehicle based on the driving data through a first Kalman filter; and determining, by a second Kalman filter, a three-dimensional velocity of the target vehicle based on the lateral velocity, the longitudinal velocity, and the IMU data. In this way, the longitudinal speed and the lateral speed of the target vehicle can be accurately obtained, and therefore the positioning accuracy is improved.

    本申请公开了一种车辆状态确定方法、装置、设备、介质及产品。该方法包括:获取目标车辆的行驶数据,行驶数据包括纵向速度、前轮转向角和惯性导航系统IMU数据;通过第一卡尔曼滤波器,基于行驶数据确定目标车辆的侧向速度;通过第二卡尔曼滤波器,基于侧向速度、纵向速度和IMU数据确定目标车辆的三维速度。这样,可以准确地得到目标车辆的纵向速度和侧向速度,从而提高定位的准确性。
