Software Development And Implementation Based On MPC5646C On-board Ethernet Communication System

With the improvement of people's living quality,people have more expectations on the safety,comfort and maneuverability of the vehicle,which makes the intelligent and networked development trend.Ethernet,as a new type of vehicle on-board communication mode,compared to CAN,LIN,Flex Ray and MOST has higher transmission speed,wider bandwidth,lighter weight and lower cost,and is a necessary medium to achieve intelligent and networked car.At present,Ethernet has been applied in the 360° panoramic auxiliary driving system.Based on the research development and application of domestic and foreign automobile Ethernet and combined with previous work,the project designs software of the on-broad Ethernet communicaiton system on the freescale MPC5646 C,and builds the model with reference to 360 ° panoramic auxiliary driving system.The main research is as follows:1)System overall architecture design research.Firstly,the oveall architecture of the vehicle Ethernet communication system is designed and designed.According to the design frame of the hardware system,the function of the hardware module is analyzed.2)Software design research.To identify system software requirements,design software programs based on MPC5646 C microcontroller research software framework.3)Model framework design research.Reference to 360 ° panoramic auxiliary driving system,Build the plan and build the model of the onboard Ethernet communication system.To achieve real-time transmission of image data via the on-board Ethernet,is one of the cars in recent years data interaction solution,in accordance with the " Internet Plus" era of automobile,boosters the development automatic driving,vehicle networking and unmanned vehicles,it has important practical significance and engineering value.
