Multi-power-operated control method and system for hybrid power vehicle

Abstract

The invention provides a control method and a system of multiple energy sources of the mixed hybrid vehicle, which comprises: an explaining module of the driving behaviors of the drivers; a mode determination and ability estimation module; a target confirmation module; and a generating module of the control instruction. The explaining module of the driving behaviors of the drivers confirms the needed driving / braking torque of the whole vehicle which is reflected on the wheels by the drivers under the current status. Meanwhile the mode determination and ability estimation mode completes the confirmation of the current operation mode of the mixed power system and the ability calculation of the charging / discharging of the power battery group, and confirms the current ability of the driving / power generation of the motor. The target confirmation module completes the confirmation calculation of the target torque of the two big power supplies of the mixed power system under the current status. The control instruction generates a mode port to confirm the corresponding execution instruction of the actuator. The control method and system of multiple energy sources of the mixed hybrid vehicle has the advantages of reducing the complexity of the control system of the power train assembly of the multiple energy sources of the prior hybrid vehicle, and ensuring the clarification and generalization of the modular structure of the power train assembly control system of multiple energy sources of the whole vehicle of the original complicated mixed hybrid vehicle.

Description

technical field [0001] The invention relates to an automobile energy control method and system, in particular to a multi-energy control method and system for a hybrid electric vehicle. Background technique [0002] In order to meet people's increasingly stringent technical requirements for both environmental protection and energy saving of automobiles, before the battery energy storage technology and fuel cell technology have made rapid progress, hybrid electric vehicles will gradually replace traditional fuel vehicles for a long period of time and become the modern automobile. mainstream models. Compared with traditional vehicles that use internal combustion engines as power sources, hybrid vehicles have more power sources in terms of energy sources. Therefore, how to coordinate the energy distribution and retraction of the engine and motor, as well as the power battery pack, so as to optimize the output efficiency of the hybrid power system, while ensuring low emissions o...
