Description of drawings
Fig. 1 is single motor deep hybrid power system configuration scheme drawing of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further description: as shown in Figure 1; Single motor deep hybrid power system configuration; Comprise driving engine 1, dynamic coupling device 9, change-speed box 4 (comprising conventional clutch and change-speed box body) and electrokinetic cell 7, wherein dynamic coupling device 9 comprises drive motor 3 and coupled clutch 2.It is characterized in that: the crankshaft output end of driving engine 1 is connected with coupled clutch 2 driving disc spacing pressings; The rotor shaft two ends of drive motor 3 are connected with the clutch plate and change-speed box 4 input ends of coupled clutch 2 respectively; The mouth of change-speed box 4 arrives drive wheels 5 through main reduction gear and diff 6 with transmission of power; Electrokinetic cell 7 realizes that with drive motor 3 high-tension current is connected through electric machine controller 8.
In practical implementation, drive motor 3 and coupled clutch 2 is integrated, realize modular design; Train has been cancelled engine accessory power ratings such as conventional electric generators, traditional starter, power steering pump with intergral reservoir and traditional compressor before the driving engine, and structure is more compact.Coupled clutch 2 can escape engine 1 and being connected of drive motor 3, and realizes the pure motor driving of vehicle; Drive motor 3 can be through combining coupled clutch fire an engine 1.Change-speed box 4 is an automatic transmission with hydraulic torque converter, can adopt any in two coupled clutch automatic transmission with hydraulic torque converters (DCT), hydraulic automatic speed variator (AT), toric transmission (CVT) and the AMT automatic machincal transmission (AMT).Coupled clutch 2 both can adopt the dry type coupled clutch, also can adopt the wet type coupled clutch.
During vehicle '; Entire car controller is through CAN signal and control unit communications such as driving engine, change-speed box, motor and battery; Receive each assembly mode of operation of power system in real time; And, realize the management of the various mode of operations of hybrid power system and the real-time control of each assembly mode of operation according to chaufeur demand and vehicle '.With reference to hybrid power system configuration shown in Figure 1, several kinds of hybrid power mode of operations below mainly can realizing:
1) idling warming-up pattern.When the vehicle completion that powers on, and when being in halted state, because ECT Engine Coolant Temperature is lower, power system gets into idling warming-up pattern.This moment, coupled clutch 2 was in released state, driving engine 1 tickover.
2) idle stop pattern.When vehicle stops, and ECT Engine Coolant Temperature is when higher, and power system gets into the idle stop pattern.This moment, coupled clutch 2 was in bonding state, and driving engine 1 shuts down.
3) stopping for charging pattern.When vehicle stops, and electrokinetic cell 7 electric weight are when low, and power system gets into the stopping for charging pattern.Driving engine 1 high idle speed work this moment, drive motor 3 give electrokinetic cell 7 chargings, and coupled clutch 2 is in released state.
4) electric-only mode.Lower when the power demand of vehicle, the speed of a motor vehicle is not high, and electrokinetic cell 7 electric weight are when higher, power system is with electric-only mode task driven vehicle '.Coupled clutch 2 separation this moment, electrokinetic cell 7 gives drive motor 3 power supplies, and the power of drive motor 3 is delivered to wheel 5 through change-speed box 4, main reduction gear and diff 6, and powered vehicle is gone, and the gear of change-speed box 4 automaticallyes switch according to the speed of a motor vehicle and accelerator open degree.
5) engine drive pattern.When the fuel oil that is positioned at driving engine 1 when the vehicle power demand was efficiently distinguished, power system was with engine drive mode activated vehicle ', and this moment, coupled clutch 2 combined, and drive motor 3 is in the servo-actuated state; As this moment electrokinetic cell 7 electric weight low excessively, then driving engine 1 also will be exported the extra power of a part except powered vehicle, be electrokinetic cell 7 chargings through drive motor 3, coupled clutch 2 combinations this moment, drive motor 3 is in generating state.
6) motor assistant mode.Go up in limited time in the efficient district of fuel oil that surpasses driving engine 1 when the vehicle power demand, and power system is gone with motor assistant mode powered vehicle.Coupled clutch 2 engages at this moment, driving engine 1 and drive motor 3 driven in common vehicle '.
7) slide/braking mode.After chaufeur unclamped Das Gaspedal or steps on brake pedal, power system got into and slides/braking mode.Entire car controller receives signals such as brake pedal, drive motor 3, electrokinetic cell 7 electric weight, distributes the size of regenerative brake power automatically, coupled clutch 2 separation this moment, and drive motor 3 is in generating state, converts vehicle energy into electric energy and gives electrokinetic cell 7 chargings; Cause shorten service life for preventing that electrokinetic cell 7 from overcharging, when being higher than higher limit like electrokinetic cell 7 electric weight, vehicle only carries out conventional hydraulic braking.
