Intelligent network connection hybrid power vehicle domain control system and control method thereof

Abstract

The invention relates to an intelligent network connection hybrid power vehicle domain control system and a control method thereof, and the system comprises a central controller which is responsible for supervision and scheduling; the sub-control domain, the information acquisition domain, the intelligent network connection domain and the automatic driving domain are in communication connection with the central controller through the gateway 1; the vehicle body control domain is in communication connection with the central controller; the energy management domain and the power system auxiliary control domain are in communication connection with the central controller through a gateway 2; the driving assistance domain, the chassis control domain and the power system control domain are in communication connection with the central controller through the gateway 3. The intelligent network connection hybrid power vehicle control system is divided by taking a'domain 'as a unit, each domain can operate independently, hardware resources are configured according to function requirements of each domain, efficient processing is achieved, and cost is reduced; the control and information scheduling of each domain are realized through the combination of the central processing unit and the gateway, so that the mutual influence among the domains is reduced, the situation that the whole vehicle is paralyzed due to abnormity is avoided, and the robustness of the system is effectively enhanced.

Description

technical field [0001] The invention belongs to the technical field of automobile control, and in particular relates to an intelligent network-connected hybrid vehicle domain control system and a control method thereof. Background technique [0002] Under the blessing of energy crisis and environmental pollution problems, the development of new energy vehicles is imminent. Among them, intelligent networked hybrid vehicles do not have the mileage anxiety of pure electric vehicles, but also can improve fuel efficiency and reduce exhaust emissions. However, due to the introduction of multiple motors including an engine, the degree of freedom of the system is increased, and control becomes difficult. In order to give full play to the advantages of intelligent networked hybrid power, coupled control algorithms with a large amount of calculation are applied, so the performance of the controller needs to be improved. Moreover, in recent years, the Internet of Vehicles technology,...
