The present invention relates to a gear shifting control method for a parallel hybrid power system. The present invention comprises the gear shifting operation control steps for a power unit controller in four states of independent drive by an engine, independent drive by an electromotor, combined drive by the engine and the electromotor and power generation by the electromotor driven by the engine. The present invention is characterized in that the gear shifting control method for a parallel hybrid power system comprises a step that the speed regulation control of the electromotor by the power unit controller in the gear engaging operation of an automatic mechanical speed changer and a step that the speed regulation control of the motor by the power unit controller in the coupling operation of a clutch of the automatic mechanical speed changer. With the present invention, the gear shifting control process by means of the cooperation of the power unit controller and the automatic mechanical speed changer in the running process of a parallel hybrid power electric automobile adopting the automatic mechanical speed changer as a driving device is realized, and furthermore, the gear shifting process of a hybrid power automobile is ensured smooth, and the driving comfortability is increased.
Description
(1) technical field
The present invention relates to the electric automobile during traveling control technology, be suitable for adopting the parallel connection type hybrid power system motor vehicle driven by mixed power of automatic mechanical transmission.
(2) background technology
Compare with orthodox car, satisfying the electronlmobil (EV, Electric Vehicle) that the automobile emission regulation of increasingly stringent requires is the final direction of development of automobile.Because electrokinetic cell reaches in price in performance, the development of pure electric automobile never gets a desired effect.Mixed power electric automobile (HEV between orthodox car and pure electric automobile, HybridElectric Vehicle), because its small investment, implementation strong, be content with very little following Abgasgesetz and energy-conservation requirement are the emphasis of many in the world car company research and development.
So-called mixed power electric car (HEV) share driven by power and auxiliary power unit (APU, Auxiliary PowerUnit) on the automobile.Its control system by the advanced person will have combustion engine now and combine with certain accumulator for accumulating energy part (mainly being heavy-duty battery or ultracapacitor), realize best energy distribution, reduce the oil consumption of combustion engine significantly, reduce exhaust emission to greatest extent.The mixed power electric car of parallel structure is flexible with form, and is simple relatively on the structure, obtains more development.At present, the hybrid vehicle of exploitation adopts parallel power system structure mostly.In order to make combined power system reasonably carry out work according to what the running condition of automobile was coordinated, power assembly controller is the key that realizes the low oil consumption of HEV, anti-emission carburetor design objective.
As the kernel control chip of hybrid power system, the development research of power assembly controller becomes the important research exploitation direction in electric vehicle engineering development in recent years and the industrialization process.In recent years, abroad released one after another and be applied to the power assembly controller of different automobile types.For example, the energy output of general Precept hybrid drive train AIPM (Automotive Integrated PowerModule) may command motor and driving engine distributes, and has functions such as energy management, regenerative brake, battery status judgement.At present, existing power assembly controller is still useless in cooperating automatic mechanical transmission to finish the function of gear-change operation.
(3) summary of the invention
The present invention is that the technical matters that is solved provides a kind of gear-shifting control method that is used for parallel connection type hybrid power system.
The technical solution used in the present invention is: the technical solution used in the present invention is the drive pattern different according to hybrid power, and power assembly controller adopts different gear shift controlled step, the gear shift controlled step of assembly controller when the driving engine independent drive is arranged respectively; The gear shift controlled step of assembly controller during the motor independent drive; Driving engine and motor are united the gear shift controlled step when driving; Gear shift controlled step when engine drive, electric power generation.
The key of gearshift procedure is that variable gear enters the preceding speed control that adds input shaft of engagement, and power-transfer clutch is in the speed control in conjunction with preceding adding input shaft.
The gear-shifting control method of this power assembly controller can make the transmission adopted automatic mechanical transmission of parallel hybrid electric vehicle, and guarantees good shift quality.
The beneficial effect that the present invention has: can realize adopting in the tight parallel hybrid electric vehicle driving process of automatic mechanical transmission driving device, the gear-shifting control process that power assembly controller cooperates with automatic mechanical transmission, and then guarantee to improve driver comfort by the smooth-going of hybrid vehicle gearshift procedure.
(4) description of drawings:
The gear shift control flow of Fig. 1 power assembly controller
(5) specific embodiment:
Be described further as follows below in conjunction with accompanying drawing to enforcement of the present invention:
After parallel type hybrid dynamic automobile power assembly controller receives the gear shift request signal of automatic mechanical transmission, enter gear shift control service routine.Assembly controller is at first judged the residing drive pattern of current mixed power electric car, enters corresponding gear shift control flow according to different drive patterns.
Unite when driving when driving engine and motor, assembly controller at first commands driving engine to reduce horsepower output, promptly reduces engine throttle, and with the horsepower output zero setting of motor, waits for that then automatic mechanical transmission disconnects power-transfer clutch and the variation of gear signal; When gear signal when neutral position becomes non-neutral position, target gear when promptly this non-neutral position is operated for the automatic mechanical transmission engage a gear, assembly controller is then according to calculation of parameter input shaft rotating speeds such as current vehicle speed, target gear transmitting ratio, final ratios, and at first motor carried out speed control with this rotating speed as rotating speed of target; When motor speed satisfies the engage a gear operation, signal is finished in the speed governing of assembly controller output motor, and the wait change-speed box is finished the engage a gear operation, assembly controller commander driving engine carries out speed control simultaneously, the rotating speed of power-transfer clutch input and output shaft is reached unanimity, for the combination of automatic transmission with hydraulic torque converter control clutch pulsation-free creates conditions.After the status signal indication power-transfer clutch combination of power-transfer clutch, assembly controller recovers the horsepower output of driving engine and motor, and gearshift procedure finishes.
When dynamic assembly was in engine drive, electric power generation mode of operation, gearshift procedure and driving engine and motor united that to drive gearshift procedure similar.
When the driving engine independent drive, gearshift procedure does not have motor horsepower output control process, has only the preoperative motor speed control process of change-speed box engage a gear.
When the motor independent drive, gearshift procedure does not have driving engine horsepower output control process and motor speed control process.
Two rotating speed controls of driving engine and motor are the keys that realizes the parallel connection type hybrid power system gear-shifting control process of employing automatic transmission with hydraulic torque converter, are to realize gearshift procedure, guarantee the necessary condition of shift quality.
