Positioning error monitoring using vehicle state information is described. A computing system associated with the vehicle may determine a current state of the vehicle, such as location, location, orientation, speed, acceleration, etc. The vehicle computing system may determine one or more metrics associated with a state of the vehicle. The metric may include a variance associated with the state, a residual associated with a measurement corresponding to the state, or a correction factor applied to correct for the input error. The computing system may determine whether the metric exceeds a threshold. Based on the threshold exceeding, the computing system may determine one or more errors associated with the state of the vehicle. The vehicle computing system may control the vehicle based on the one or more errors. 描述了使用车辆状态信息的定位误差监控。与车辆相关联的计算系统可以确定车辆的当前状态，例如，地点、位置、朝向、速度、加速度等。车辆计算系统可以确定与车辆的状态相关联的一个或多个度量。度量可以包括与该状态相关联的方差、与对应于该状态的测量相关联的残差、或被应用以校正输入误差的校正因子。计算系统可以确定度量是否超过阈值。基于阈值超出，计算系统可以确定与车辆的状态相关联的一个或多个误差。车辆计算系统可以基于一
