Study on energy utilization rate under the urban driving condition

With the rapid development of urban economy and the increase of motor vehicles, the city traffic brings several negative impacts and environment pollution is more and more serious increasingly. Thus, it has become very important to reduce the vehicle emission. This paper addresses this context by introducing the research background about the driving condition and constructing the energy consumption model. On that basis, this paper presents the concept of the energy utilization rate and calculation model, and moreover, applies it under the European driving condition and brings out the energy utilization rate of vehicle, which provides the recommendations for the vehicle safety and environmental protection.
