Abstract

The invention discloses a serial-to-parallel control method of an electrical-electric connecting type hybrid power system. The method is that when a vehicle meets the condition of entering parallel connection and an engine is failed to be started, ISG (Integrated Starter Generator) is subjected to rotating speed control, namely, the target rotating speed is the rotating speed of a main motor; the engine supplies air when reaching the set rotating speed n1, and is ignited when reaching the set rotating speed n2; when starting successfully, the ISG remains the rotating speed control; on the basis of the rotating speed of the main motor, the engine control is replaced by accelerator control, and a proper accelerator value is provided; when the rotating speed difference between the engine and the main motor is less than the set rotating speed difference value, a clutch is connected, and the vehicle enters the parallel connection mode. The method has the outstanding characteristics that the ISG is subjected to rotating speed control under a serial-to-parallel mode; the engine is subjected to accelerator control and the proper accelerator value is provided on the basis of the rotating speed of the main motor, so that the speed regulating can be responded fast; in addition, the response of the engine in the parallel connection mode is faster than that of the mode that the engine control is performed and the accelerator value is 0 during speed adjustment; the hybrid power system is free of power cut-off after the clutch is connected.

Description

A kind of pneumoelectric series-parallel hybrid electric system series connection turns control method for parallel
Technical field
The present invention relates to the series connection of a kind of pneumoelectric series-parallel hybrid electric system and turn control method for parallel.
Background technology
Be illustrated in figure 1 existing pneumoelectric series-parallel hybrid electric system, as seen from the figure, this system comprises coaxially arranged driving engine 1, ISG motor 3 and mair motor 5, wherein, ISG motor 3 and engine output shaft are in transmission connection by torsion vibration absorber 2, and be in transmission connection by power-transfer clutch 4 between ISG motor 3 and mair motor 5, mair motor directly connects drive axle and drives car load.According to the mode of operation of power-transfer clutch 4, this system can be divided into series model and paralleling model, and series model refers to that power-transfer clutch is in released state, and mair motor is unique drive element; Paralleling model refers to that power-transfer clutch combines, and driving engine or mair motor are drive elements.
Current series connection turns paralleling model following two kinds of modes: (1) control of engine speed, ISG direct torque: if driving engine is not shut down, driving engine adopts rotating speed to control, and rotating speed of target is mair motor rotating speed, ISG motor adopts direct torque, and target torque is 0Nm; If driving engine is shut down, ISG motor adopts direct torque by engine starting success, and then driving engine adopts rotating speed to control, and rotating speed of target is mair motor rotating speed, and ISG motor adopts direct torque, and target torque is 0Nm.Because gas blowing engine response is comparatively slow, and there is the factors such as speed governing is unstable and cause series connection to turn paralleling model to transform slow.(2) ISG rotating speed controls, and driving engine adopts Throttle Opening Control and is 0 throttle: if driving engine is not shut down, and ISG adopts rotating speed to control, and rotating speed of target is mair motor rotating speed, and driving engine adopts Throttle Opening Control and is 0 throttle; If driving engine is shut down, ISG motor first adopts direct torque by engine starting success, and then ISG adopts rotating speed to control, and rotating speed of target is mair motor rotating speed, and driving engine adopts Throttle Opening Control and is 0 throttle.The shortcoming of this mode is: when driving engine has load (as air compressor of air conditioner work etc.) or mair motor rotating speed is higher, ISG is limited by Power Limitation own causes speed governing slower; Power-transfer clutch participates in driving in conjunction with the instruction of rear engine response full-vehicle control, and because gas machine is from 0 throttle to target throttle low-response, driver feels that vehicle exists power interruption problem.
As from the foregoing, now series connection turns a mode in parallel and has that patten transformation is slow, there is the problems such as power interruption after patten transformation.
Summary of the invention
The object of this invention is to provide the series connection of a kind of pneumoelectric series-parallel hybrid electric system and turn control method for parallel, the patten transformation that existing mode exists is slow to solve, exist after patten transformation the problem of power interruption.
In order to realize above object, the technical solution adopted in the present invention is: a kind of pneumoelectric series-parallel hybrid electric system series connection turns control method for parallel, comprises the steps:
(1) when vehicle meet enter condition in parallel time, judge whether driving engine has completed machine, if do not complete, then ISG motor employing rotating speed control, rotating speed of target is mair motor rotating speed;
(2) when engine speed reaches the rotating speed n1 of setting, to driving engine air feed;
(3) when engine speed reaches the rotating speed n2 of setting, engine ignition;
(4) when engine speed reaches the rotating speed n3 of setting, driving engine has completed machine, and now ISG adopts rotating speed to control, and follows mair motor rotating speed, and driving engine adopts Throttle Opening Control, and given throttle value;
(5) when driving engine and mair motor speed discrepancy are less than setting speed difference, power-transfer clutch combines, and vehicle enters paralleling model, and driving engine participates in driving.
The rotating speed n1 of setting is 200rpm.
The rotating speed n2 of setting is 400rpm.
The rotating speed n3 of setting is 550rpm.
The setting speed difference of driving engine and mair motor is 50rpm.
The outstanding feature that pneumoelectric series-parallel hybrid electric system of the present invention series connection turns control method for parallel is that series connection is when turning paralleling model, ISG motor adopts rotating speed to control, follow the rotating speed of mair motor, and driving engine is Throttle Opening Control and given suitable throttle value, speed governing response is very fast, and enter in paralleling model rear engine response ratio speed regulation process adopt engine control and throttle value be 0 mode want fast, hybrid power system power failure-free after power-transfer clutch combines.

Fig. 2 is that the present invention connects and turns paralleling model control flow chart.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention is described further.
As shown in Figure 2, pneumoelectric series-parallel hybrid electric system of the present invention series connection turns control method for parallel and comprises the steps:
(1) when vehicle meet enter condition in parallel time, judge whether driving engine has completed machine, if driving engine has completed machine, the control of now ISG employing rotating speed, follow mair motor rotating speed, engine control is Throttle Opening Control, and given suitable throttle value; If do not complete, then ISG motor adopts rotating speed to control, and rotating speed of target is mair motor rotating speed;
