The maximum filtering distance calculating step is performed to configure a processing unit to calculate a maximum filtering distance according to a dynamic adjustment distance parameter. The vehicle distance calculating step is performed to configure a modem to obtain a host vehicle location message and a vehicle-to-everything (V2X) safety packet. The V2X safety packet includes a remote vehicle location message, and then the host vehicle location message and the remote vehicle location message are calculated to generate a vehicle distance. The packet filtering step is performed to configure the modem to compare the vehicle distance with the maximum filtering distance from the processing unit to generate a comparison result, and judge whether the V2X safety packet is a passed packet according to the comparison result."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distance-based packet filtering method for comparing vehicle distance with maximum filtering distance and system thereof","description":"A distance-based packet filtering method includes a maximum filtering distance calculating step, a vehicle distance calculating step and a packet filtering step.
