Research and design of APP for new energy vehicles electronic control system based on cloud platform

New energy vehicles are energy-efficient and environmental, however, their safety performance is still unstable. With the long-term operation of the vehicle, its electronic control parameters are no longer suitable for the current vehicle requirements, resulting in the decline of vehicle energy efficiency and performance. So it is necessary to monitor the vehicles in real time and optimize the energy control. Therefore, the development of APP based on Android system and cloud platform is researched. Firstly, an improved scheme of the communication mode and communication protocol between APP and iECU or cloud platform for data interaction is proposed. Secondly, it is necessary to focus attention on the key technology that SQLite involved in the development process of APP, which comes from the database of Android system. In addition, the design and research of main functional interfaces are described in detail. That is the “Data management” and “MAP calibration”. Finally, it is necessary to test the functions of APP by iECU or cloud platform. The experiment demonstrates that the developed APP can communicate well with iECU and cloud platform servers, and it can collect and process the data of vehicles. Moreover, the interface of APP is friendly. It is quite easy to operate for users, so as to achieve the desired design goals. Finally, the real-time monitoring and energy optimization of the key parameters of the vehicle are carried out, so that the vehicle can always run safely and efficiently.
