Abstract

The invention provides a whole vehicle data time synchronization method and device, electronic equipment and a storage medium, wherein the method comprises the steps: respectively checking and judgingthe availability of a PPS signal and a GNSS signal, judging whether the association of the PPS signal and the GNSS signal is correct or not when the PPS signal and the GNSS signal are both in an available state, calculating the system time if the association is correct, and adding a corresponding timestamp to vehicle sensor data. By means of the method, UTC time synchronization conditions can beaccurately judged, effectiveness of time synchronization is guaranteed, it is guaranteed that time synchronization results are accurate and reliable, and meanwhile stability and adaptability of time synchronization under various devices and scenes are improved.

Description

technical field [0001] The invention relates to the field of data synchronization, in particular to a vehicle data time synchronization method, device, electronic equipment and storage medium. Background technique [0002] With the development of advanced assisted driving and automatic driving technology, the number of integrated sensors installed in vehicles is increasing. In assisted driving or automatic driving, the sensor data is accurately aligned (interpolated) and synchronized (predicted or compensated) in time and space. , which is very important for the fusion of multi-source sensors for subsequent perception, planning and decision-making. Different data sources are converted to the same time scale, and the predicted or compensated sensor data is fused and calculated. In engineering practice, it is often necessary to unify signals such as GNSS, IMU, and vehicle status to the same time scale, and then proceed to the next step of calculation. [0003] At present, th...
