Abstract
The invention discloses a central control system of a hybrid electric vehicle, which comprises an engine control module and an electric motor control module, wherein the engine control module controls an engine; the electric motor control module controls an electric motor; the engine control module and the electric motor control module are integrated on a circuit board, and operate independently and respectively. The central control system has the advantages that the engine and the electric motor are classified as two sets of systems, provide torque for a vehicle transmission system, and can drive the hybrid electric vehicle jointly or singly on different pavements; an electronization function module is optimally integrated, the lightweight of the overall hybrid electric vehicle and the synchronization and harmonization of modules are beneficial to achievement, and the safety and reliability of the overall hybrid electric vehicle are improved greatly.
Description
Technical field
The present invention relates to a kind of master control system of hybrid vehicle.
Background technology
The whole-control system of existing hybrid vehicle is based on the distributed network structure control system of dual bus, the i.e. low speed bus of the high-speed CAN bus of drive system and bodywork system.Each node of high-speed CAN bus is the ECU of each subsystem.Low speed bus arranges by physical location the regional autonomy that node, fundamental principle are based on the locus, and the electric elements that namely physical location is close are connected to a node control unit (ECU), and the signal of each element carries out communication by ECU and bus.No matter be high-speed CAN bus or low speed CAN bus, its structure is independent control structure, establishes one's own system, and is the single module master mode.Wherein, CAN is the abbreviation of controller local area network (Controller Area Network, CAN).), be the serial communication protocol of ISO international standarkdization.Above-mentioned control system has complex circuit, wire harness increases, and is difficult to realize communication and resource sharing, the harmony between each module, poor synchronization.
Therefore, need a kind of new control system to address the above problem.
Summary of the invention
The objective of the invention is the deficiency for the existence of prior art control system, a kind of master control system of efficient hybrid vehicle is provided.
For achieving the above object, the master control system of hybrid vehicle of the present invention can adopt following technical scheme:
A kind of master control system of hybrid vehicle, comprise engine control module and motor control module, described engine control module control engine, described motor control module controls electrical motor, described engine control module and described motor control module integration are in a circuit card, and described engine control module and described motor control module work alone respectively.
Compare with background technology, the master control system of hybrid vehicle of the present invention makes driving engine and electrical motor adhere to two cover systems separately, can provide moment of torsion to automotive transmission independently respectively, not only can jointly drive but also can drive separately on different road surfaces.Electronic functional module is optimized integrated, helps to realize the lightweight, the synchonize between each module and coordinationization of hybrid electric vehicle complete vehicle, greatly promote the safety and reliability of car load.
The specific embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
The master control system of hybrid vehicle of the present invention, comprise engine control module and motor control module, the engine control module control engine, motor control module controls electrical motor, engine control module and motor control module integration are in a circuit card, and engine control module and described motor control module work alone respectively.Electronic functional module is optimized integrated, helps to realize the lightweight, the synchonize between each module and coordinationization of hybrid electric vehicle complete vehicle, greatly promote the safety and reliability of car load.
Hybrid vehicle comprises electrokinetic cell, and master control system also comprises and discharges and recharges control module, discharges and recharges process of charging and discharge process that control module is controlled described electrokinetic cell.When hybrid vehicle deceleration, brake and descending, discharge and recharge control module and control power battery charging.When hybrid vehicle starts, discharge and recharge control module and control the electrokinetic cell discharge.This system makes hybrid vehicle have following 2 abilities: ⑴ driving engine and electrical motor adhere to two cover systems separately, can provide moment of torsion to automotive transmission independently respectively, not only can jointly drive but also can drive separately on different road surfaces; ⑵ combine traditional combustion engine, driven by power and closed-center system.Like this, when hybrid electric vehicle starts, (Integrated starter and Generator, ISG) energy of electrical consumption electrokinetic cell drive turn of engine to 2000 turns above, allow driving engine be always operating near the state of fuel consumption and emission the best, the good results are evident when waiting red light, and this cries treats fast start-stop.When normally travelling, on one side driving engine drives automobile, Yi Bian drive the ISG electric power generation, give the electrokinetic cell stored energy, electric energy also charges to accumulator jar by DC simultaneously, serves as the small generators effect of conventional car; When acceleration or climbing, because the hybrid engine discharge capacity is less than conventional car, need to provide high pulling torque by the energy of ISG motor, storage battery provides energy, realizes accelerating power-assisted.When deceleration, brake and descending, can reclaim the inertia energy of a part of automobile by motor, realize energy feeding braking.By above-mentioned measure, the fuel saving ratio of hybrid power control system can reach 20%.Compare with other conventional cars, this scheme more easily satisfies the Ou Si effluent standard.
As mentioned above, the master control system of hybrid vehicle of the present invention is optimized electronic functional module integrated, help to realize lightweight, the synchonize between each module and coordinationization of hybrid electric vehicle complete vehicle, greatly promote the safety and reliability of car load.When deceleration, brake and descending, can reclaim the inertia energy of a part of automobile by motor, realize energy feeding braking; (Integrated starter and Generator when hybrid electric vehicle starts, ISG) energy of electrical consumption electrokinetic cell drive turn of engine to 2000 turns above, allow driving engine be always operating near the state of fuel consumption and emission the best, by above-mentioned measure, the fuel saving ratio of hybrid power control system can reach 20%.Compare with other conventional cars, this scheme more easily satisfies the Ou Si effluent standard.
