Description
Technical field
The present invention relates to technical field of engines, relate in particular to a kind of driving engine start and stop control method and control system that is used for series hybrid electric vehicle.In addition, the invention still further relates to a kind of series hybrid electric vehicle that comprises above-mentioned driving engine start and stop control system.
Background technology
Hybrid vehicle is meant the automobile that two above propulsions source (driving engine and storage battery) is housed on the car.Hybrid vehicle can be divided into series hybrid electric vehicle, parallel type hybrid dynamic car and series parallel hybrid power car three major types according to its power transmission route.
The dynamic assembly of series hybrid electric vehicle is made up of driving engine, electrical generator and electrical motor three part power; Connect with series system between them; The engine driven generators generating, electric energy is transported to battery or electrical motor through controller, drives automobile by electrical motor through speed-changing mechanism.During little load by battery driven motor, again by wheel driving motor; By the engine drives generator for electricity generation, and then driving motor is again by wheel driving motor during big load.
Tandem power is applicable in the city operating condition of frequent starting and low speed driving, for example usually is used for city bus.The power of city bus comprises driving engine and storage battery; Because the city bus start and stop are frequent, its power that needs is frequent variations also, therefore; How controlling driving engine makes it realize automatic start-stop according to battery electric quantity and vehicle driving-cycle; Both having guaranteed that driving engine responded fast, and can play the effect of energy-saving and emission-reduction again, is vital problem in the series hybrid electric vehicle.
Please refer to Fig. 1, Fig. 1 is the FB(flow block) of the driving engine start and stop control method of series hybrid electric vehicle of the prior art; Briefly introduce the defective that exists in the working process of this control method below.
As shown in Figure 1, this driving engine start and stop control method mainly comprises the steps:
S1 ': obtain SOC (state of capacity, the i.e. residual capacity state) value of battery in real time, the delivery quality of driving engine and engine operating condition parameter;
S2 ': judge whether driving engine is in stopped status, if get into step S3 '; If not, get into step S4 ';
S3 ': whether whether the SOC value of judging battery start the energy that needs when quickening less than current vehicle less than the SOC value of minimum predetermined value or battery, if get into step S5 '; If not, get into step S7 ';
S4 ': whether the SOC value of judging battery is greater than maximum predetermined value and the energy that needs greater than the current vehicle cruising, if get into step S6 '; If not, get into step S7 ';

Like this, earlier the duty parameter of the delivery quality through driving engine, driving engine calculates current vehicle and starts the energy that accelerations needs, then the SOC value through battery relatively and current vehicle startup acceleration need energy, thereby know whether driving engine needs startup.This determination methods makes above-mentioned start and stop control method have the higher characteristics of accuracy.
Special version be that above-mentioned " minimum predetermined value " refers to battery does not need electrically-charged minimum predetermined value, for example can be set to be 40% of total electric weight of battery; Above-mentioned " maximum predetermined value " refers to the maximum predetermined value that need not discharge, for example can be set to be 90% of total electric weight of battery; Certainly, above-mentioned " minimum predetermined value ", " maximum predetermined value " can also be got other numerical value, and the user can select according to the real work situation voluntarily.
The concrete mode of the ceiling capacity whether above-mentioned SOC value of judging battery need greater than the current vehicle operation can also further be set.
In the another kind of specific embodiment, above-mentioned steps S4 can be specially:
Whether the SOC value of judging said battery is greater than maximum predetermined value and the energy that needs greater than normal vehicle operation, if get into step S6; If not, get into step S8.
Adopt this method; The current SOC value that promptly requires battery is not only greater than maximum predetermined value; And the energy that needs when the SOC value of this battery also must be greater than normal vehicle operation; Fully guarantee the accuracy and the safety of start and stop control methods, further guaranteed the functional reliability of driving engine start and stop control processs.Certainly, in addition, can also judge the ceiling capacity whether the SOC value of battery needs greater than the current vehicle operation through other modes.
In further scheme, the position of Das Gaspedal that can be through detecting said series hybrid electric vehicle among the above-mentioned steps S1, the position of brake pedal obtain the delivery quality of driving engine.In this way; Can know the delivery quality of driving engine simply, intuitively; Particularly, can adopt displacement pickup to detect the position of Das Gaspedal, the position of brake pedal, so that know the delivery quality of driving engine rapidly and accurately; Certainly, can also know the delivery quality of driving engine through other modes.
In the another kind of concrete scheme, the current operational factor of above-mentioned driving engine can specifically comprise: the rotating speed of driving engine, water temperature, rate of load condensate.Know the operational factor of present engine exactly through rotating speed, water temperature and the rate of load condensate of detection of engine; Thereby delivery quality in conjunction with above-mentioned driving engine; Calculate ceiling capacity and least energy that the current vehicle operation needs exactly; Whether can satisfy current vehicle operation needs so that judge the current SOC value of battery, guarantee the accuracy and the accuracy rate of start and stop control method.Certainly, above-mentioned operational factor can also comprise other concrete parameters.
Special version be that above-mentioned driving engine can be specially diesel motor, certainly, also can be specially engine petrol.
Please refer to Fig. 7, Fig. 7 is the structural representation of a kind of specific embodiment of the driving engine start and stop control system that is used for series hybrid electric vehicle provided by the present invention.
As shown in Figure 7, the present invention also provides a kind of driving engine start and stop control system that is used for series hybrid electric vehicle, comprising: detecting device and controller;
Said detecting device is used for detecting in real time the SOC value of the battery of said series hybrid electric vehicle, the delivery quality of driving engine, and the current operational factor of driving engine;
