New energy vehicle smart assisted driving method based on large system optimization and vehicle networking

Abstract

The invention discloses a new energy vehicle smart assisted driving method based on large system optimization and vehicle networking and provides a new intelligent assisted driving technology. The method determines the optimal driving route and the optimal driving speed based on the traffic of the city as a study object and large system intelligent optimization. From a starting node to a destination node, the one optimizing process for acquiring the optimal driving route is replaced by the process of acquiring the optimal driving route through multi-objective rolling optimization and continuous adjustment of the optimizing strategy according to the real-time road condition information. Through the vehicle networking, the optimal vehicle speed of the traffic large system is acquired. According to the error between the optimal vehicle speed and actual vehicle speed, through adjustment of the actual vehicle speed based on a vehicle-mounted controller, the optimal vehicle speed can be acquired in real time and the self-adaptive cruise control is realized. A relationship of a flow, a vehicle speed and a congestion degree is built. Aiming at the minimum congestion level, the optimal driving speed is calculated based on the intelligent optimization of the large traffic system.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, in particular to an intelligent assisted driving method for new energy vehicles based on large-scale system optimization and Internet of Vehicles. Background technique [0002] New energy vehicles (pure electric vehicles and hybrid electric vehicles) usually contain electric drive devices with fast dynamic response characteristics, so they are suitable for intelligent assisted driving and unmanned driving applications such as adaptive cruise, driving deviation correction and agile navigation. [0003] At present, the Internet of Vehicles technology is still in its infancy, limited to GPS positioning and navigation, in-vehicle status reporting and Internet services, etc., but focusing on ecology, reducing fossil fuel consumption and carbon emissions is the development trend of Internet of Vehicles, especially carbon Emissions control, intelligent collaborative transportation and agile navigation...

Problems solved by technology

[0005] Although so-called intelligent navigation has also appeared in navigation, usually only when the originally planned route is seriously congested, the driver is notified to choose another route. Preventing congestion beforehand doesn't help
