Problems solved by technology
[0002]With the development of science and technology and the improvement of people's living standards, vehicle communication has become an area that people have more contact with in daily life, especially vehicle positioning and navigation. It is deeply relied on by many car owners, but the GPS-based positioning system may have problems such as poor communication, data delay, and time synchronization when the weather is bad or entering a tunnel, which may lead to inaccurate vehicle location information. Problems such as navigation route errors, especially for technologies such as intelligent driving that require high vehicle location information, time out of sync can bring serious consequences

The invention relates to a vehicle time calibration method, which comprises the following steps of S1, providing a camera, and defining a detection range of the camera; S2, when the vehicle enters thedetection range of the camera, acquiring the time t1 of the vehicle; S3, obtaining the time t0 when the vehicle passes through the camera; and S4, calibrating the real-time time of the vehicle basedon the difference between the time t0 and the time t1. The invention relates to a vehicle time calibration system which comprises an image acquisition module, a range detection module, a data processing module and a signal transmission module. According to the method and system, the vehicle time can be accurately synchronized, the problem of network delay is avoided, and the vehicle position information is more accurate, so that the vehicle driving safety is ensured.
