Hybrid electric vehicle complete vehicle system as well as multi-energy control system and control method thereof

Abstract

The invention relates to a full vehicle system of hybrid vehicles, a multi-energy control system of the full vehicle system, and a corresponding multi-energy control method. The full vehicle system of hybrid vehicles comprises a multi-energy controller system, a motor main body system, an energy storage main body and control system, an engine and a full-vehicle electric-mechanical system. Based on the control system, the invention discloses an energy control method including special processing strategy and algorithm for multi-energy information, energy control of full hybrid vehicle under power-assisted torsional moment, energy control of full hybrid vehicle under energy recovery mode, temperature control strategy of an energy storage unit, and automatic start / stop of the engine. A high-voltage battery of the energy storage unit configured in the full hybrid vehicle has higher work efficiency and higher service life when subjected to the control scheme of the invention, and the full vehicle of the invention meets various index such as the design economy, power performance and emission performance.

Description

technical field [0001] The present invention relates to a hybrid electric vehicle vehicle system, the multi-energy control system of the vehicle system and the corresponding multi-energy control method, the multi-energy system control method in the present invention belongs to the key control in the hybrid electric vehicle vehicle control scheme One of strategy and algorithm implementation. Background technique [0002] Since the end of the last century, major auto companies in Asia, America, and Europe have begun to develop gasoline-electric hybrid vehicles. Major auto companies, including Honda, General Motors, Ford, D-C, and French Citroen, have launched or developed product cars or concept samples. car. Some experts believe that in the next ten years, 40% of the cars may adopt hybrid technology, and hybrid cars have great development prospects. [0003] As we all know, a hybrid vehicle is a new technology of power hybrid transmission based on traditional internal combu...
