Energy-heat integrated real-time management system for intelligent networked hybrid vehicles

Abstract

An intelligent network-linked hybrid electric vehicle energy-heat integrated real-time management system belongs to the technical field of energy-saving control of hybrid electric vehicles. The purpose of the present invention is to provide real-time dynamic traffic preview information by using network information, and to consider the temperature effect of the thermal chain in the optimization of vehicle energy efficiency. The energy-heat integrated real-time management system for intelligent networked hybrid electric vehicles with further improved fuel economy. The steps of the present invention are: combining traffic flow cloud data to collect real-time traffic information flow on all road sections, determining the global route, combining the speed information of queues on the driving route, and transmitting the vehicle speed prediction results of long and short time scales to the hybrid vehicle power chain ‑The thermal chain dynamic coupling mechanics prediction module uses the long- and short-time-scale vehicle speed information provided by the multi-scale vehicle speed prediction module to design a real-time SOC trajectory optimization controller. The invention improves the online optimization solution efficiency and ensures the real-time performance of the system.

Description

technical field [0001] The invention belongs to the technical field of energy-saving control of hybrid electric vehicles. Background technique [0002] In recent years, with the continuous expansion of car ownership, the problem of energy consumption has become more and more serious. Hybrid technology combines the technical advantages of traditional internal combustion engine vehicles and pure electric vehicles. Compared with traditional internal combustion engine vehicles, it can greatly improve fuel economy and is an effective solution for energy saving and emission reduction of vehicles. [0003] At present, hybrid electric vehicles use energy management technology to optimize the distribution of the driving energy of the engine and electric motor in the power chain, so as to meet the driver's power demand and improve the fuel economy of the vehicle at the same time. However, the engine is not only the source of the power chain but also the source of the heat chain (the ...

Problems solved by technology

Nevertheless, the existing technology still needs to be further improved. The engine is the source of the vehicle power chain and heat chain, and energy optimization control and thermal management are "independently fighting". There is still a gap in the field, and it is impossible to guarantee that the fuel economy of the vehicle is optimal under all weather conditions

In addition, how to use dynamic network information to provide support for energy-heat integrated management still faces many technical bottlenecks
