Firstly, the development status and major issues facing mobile cloud computing are introduced to introduce mobile edge computing, and its basic concepts and advantages are explained. Then, the application scenarios of this technology in the field of connected vehicles are briefly described, and the challenges of mobile edge computing for connected vehicles are addressed - how to make offloading decisions. To solve this problem, a single-server-single-user system model is proposed, and the user's task is decomposed into multiple sub-tasks. The energy consumption of the mobile vehicle-mounted device is taken as the constraint, and the user's delay is taken as the objective function. A sub-optimal offloading scheme is proposed through analysis, and its feasibility is verified by simulation, which can effectively reduce delay and improve user experience
