Abstract

The invention discloses a communication method and device for a C-V2X protocol stack, and the method comprises the steps: receiving the data of an application layer through the C-V2X protocol stack, processing the data of the application layer, and transmitting the data through a hardware chip; receiving a request for receiving data initiated by the application layer through the C-V2X protocol stack so as to receive the data of the hardware chip, and processing the received data of the hardware chip through the C-V2X protocol stack so as to return the processed data to the application layer. According to the invention, the data security module ensures the security of data transmission; a software layering thought is used, so the v2x protocol stack can be quickly transplanted and used in any v2x equipment; rich and flexible software function interfaces are provided, more requirements of an application layer are met, the burden of the application layer is reduced, and the application layer is more focused on the design of a service scene; a plurality of application layer programs can be supported to be used, and rich application scenes of the application layer are met.

Description

technical field [0001] The present invention relates to the technical field of wireless communication protocols, and more specifically, to a communication method and device of a C-V2X protocol stack. Background technique [0002] Under the premise of the rapid development of society and the improvement of people's living standards, there are more and more vehicles on the road, and many traffic accidents have occurred. At present, autonomous driving also needs to obtain more information to make vehicles on the road safer, and v2x provides these functions to allow vehicles to obtain more information, thereby making cars on the road safer and smarter. cv2x is an advanced wireless communication technology that enables vehicles, signal lights, traffic signs, cyclists and pedestrians to communicate with each other and share information such as current status, location and action intention. V2x mainly studies the relationship between cars and cars, cars and roads, cars and people....
