Research On Key Technologies Of Vehicle Networking Terminal Device

With the increase of the vehicle quality in china, the environmental pollution aggravated, the contradiction of the road congestion and traffic management become more and more highlighted. We all know that traditional traffic monitoring measures couldn’t solve these increasingly serious problems. Hence, China gave great impetus to the construction of Intelligence Transportation System to improve the modernization level of Chinese transportation System. Against this background, relational technologies of the Internet of Vehicle are getting unprecedented attention. At present, research of this field in our country is in its initial stage. In the Internet of Vehicle, we are facing some urgent problems in the Sensor Layer, the Network Layer and the Application Layer.This thesis firstly discusses the comprehensive investigation and studies about composite technology in the perception of the Sensor Layer and the Network Layer. And the thesis illustrates core theories and development of the technologies in Sensor Layer and the Network Layer.Then, the thesis mainly focuses on the research of the Vehicle Status Sensing technologies in the Sensor Layer, also on the Driving Behavior Sensing methods.Finally, based on the research and development project of the enterprise product, the thesis designs and implements innovative terminal equipment for Network of Vehicle. This terminal equipment not only innovative pulling out design of the rearview mirror, but also merges green driving and safety driving in the respect of functions.The practical usage of this equipment demonstrates that, for some drivers with bad driving habits, the first time when they drive using this equipment, the fuel saving could reach to10%. When it comes to the highway, the equipment could help the driver saving about20%fuel. Through the device, the driver’s driving habits could be improved, which lead to a long-term fuel saving, energy conservation and environmental protection, and is of great practical significance and promotion value.
