Connected and Automated Vehicles (CAVs) not only improve the safety and efficiency of road traffic, but also have a significant impact on energy consumption of road traffic. In this paper, the main influencing factors of eco-driving technology of CAVs are studied. Firstly, the paper studies the important impact of the emergence of CAVs on energy and emissions. Secondly, the influencing factors of eco-driving technology of CAV are mainly divided into three categories: vehicle characteristics, traffic network characteristics and driver decision-making characteristics. Among them, the characteristics of vehicles have the most direct impact on eco-driving. Vehicle design, vehicle performance and the degree of network integration are the key factors affecting the energy-saving effect of CAVs. The characteristics of complex traffic network include roadside equipment, overall network transmission and CAVs market penetration rate. The most uncertain factor is the social benefit characteristics. Driver's travel decision-making and driving mileage are main factors affecting the energy-saving effect. Finally, the paper discusses the future direction of research and improvement of CAV and the formulation of relevant policies and regulations.
