Parallel type hybrid vehicles energy management and assembly coordinated control method

Abstract

The invention relates to a method for managing the whole vehicle energy of a parallel hybrid power vehicle and assembly coordination control, which belongs to the field of drive system control of the hybrid power vehicles. According to the running state of the hybrid power vehicle, the method respectively controls a control module for a control algorithm to enter the whole vehicle for electrified self-check and fault diagnosis, an ABS coordinated control module, a coordinated control module assisting an AMT to shift gear initiatively, a control module for motor initiative compensation, a control module for mode switching and energy management, a module for processing and displaying whole vehicle state information, and an initiative control module for the idling stop of an engine so as to control the energy distribution of a hybrid power drive system and the coordinated operation of each assembly of the system. The method can perform energy management on the hybrid power drive system and coordinated control on each assembly so as to achieve the optimal energy distribution among the assemblies of the hybrid power drive system, improve the fuel economical efficiency of the whole vehicle to the utmost extent, and reduce the exhaust emission of the engine, ensure that the while drive system can work reliably and efficiently to obtain the optimal performance of the whole vehicle running.

Description

technical field [0001] The invention belongs to the field of hybrid vehicle drive system control, and is suitable for hybrid vehicles using a parallel hybrid drive system. Specifically, according to the actual driving state of the parallel hybrid vehicle, the driving force and braking force required by the driver are in the hybrid vehicle. It is a control method that controls the reasonable allocation among the components of the drive system and coordinates the operation of the components of the drive system to achieve the purpose of energy saving and environmental protection. Background technique [0002] Today in the 21st century, energy and environmental issues have increasingly become severe issues that must be faced by human beings for their survival and sustainable development. As one of the clean energy vehicle technologies in the 21st century, the hybrid vehicle has become the development direction and research hotspot of future vehicles due to its low energy consump...
