Economic Driving Assistance System Considering Power Demand and Traffic

摘要

Based on the consumption analysis of energy flow in a vehicle, a new eco-driving assistance system is designed by optimizing the energy consumption of acceleration and deceleration process. During the acceleration process, comprehensive considering vehicle dynamics and fuel consumption, a new index is proposed. This index can be adjusted by drivers according to their power demands, and is used to evaluate the acceleration behaviour. Accordingly an advice will be fed back to the driver, if his/her driving becomes uneconomic. During the deceleration process, the information of preceding vehicle is used to help drivers reduce fuel consumption by maximizing the usage of the kinetic energy of vehicle body. The effectiveness of the designed eco-driving assistance system has been validated by bench tests under the standard NEDC driving cycle and naturalistic driving conditions.
