Problems solved by technology

[0003] Inevitably, there will be situations where the communication quality of the vehicle network is not good, or it is caused by the communication failure problem of the actual network, or caused by the temporary communication network interference problem, etc.
The existing vehicle-mounted equipment is an independent communication terminal. When its network signal is relatively weak, it cannot determine the specific cause by itself, let alone optimize its network communication quality.
In particular, when the vehicle's own products are subject to external interference and the network signal is poor, the user experience will be even worse

Abstract

The invention provides a vehicular network communication optimization method and system. The method comprises the steps of collecting a network signal of a vehicular device; judging whether the quality of the network signal is consistent with a threshold condition or not, if the quality of the network signal is consistent with the threshold condition, returning to the step of collecting the network signal of the vehicular device, and if the quality of the network signal is inconsistent with the threshold condition, performing a next step; obtaining data of a third party device; judging whether the data of the third party device satisfies an injection condition of the vehicular device or not, if the data of the third party device does not satisfy the injection condition of the vehicular device, returning to the step of collecting the network signal of the vehicular device, and if the data of the third party device satisfies the injection condition of the vehicular device, performing the next step; and adjusting parameters of the vehicular device and injecting the adjusted parameters. According to the method, the current network information and the previously obtained related information are obtained through utilization of network service of the third party device, modeling is employed, corresponding results are dynamically output, a servo program is established, a vehicular terminal accesses the program via BT / WIFI, and if the injection condition is satisfied, the corresponding parameters are injected into the vehicular device, so the vehicular device network communication is optimized.
