Step 203：Judge whether engine speed is higher than idling setting value：It is to send reduction throttle commands, then performs Step 204；It is no, perform step 204；
Step 204：Judge whether engine speed is less than idling setting value：It is to send lifting throttle commands, is then back to Main program；It is no, directly return to main program.
It is the idle speed value that step 201 describes in the idling setting value described in step 203, step 204, is worked as according to step 201 The idle speed value that preceding called idle speed value is judged by two above step.
During work：
Turn on the power key, program initialization.Whether main control module 01 detects engine throttle in idle position, if not having Have in idle position, then recover to idle position.Functional switch 18 is the controlling switch of the system, and also referred to as automatic mode is opened Close, whole work process is established under conditions of the unlatching of functional switch 18.
Main control module 01 continues to monitor whether air-conditioning switch 13 is opened, whether has enforced opening instruction, and the mixed automobile of electricity moves The voltage of power battery pack 2 whether less than setting full conjunction value, if without if system it is standby, now if the mixed automobile of electricity Start running and be then in pure electronic working condition；If there is either condition therein to occur, system automatic start engine.
After engine start, if the mixed transaxle 16 of electricity does not leave start bit, that is, vehicle does not travel, then sends out Motivation keeps idling mode.
When the mixed automobile of electricity is run at a low speed in, if air-conditioning switch 13 is not turned on, pure electronic and oil-fired power generating system group Conjunction forms automatic mode, during automatic mode operation：If the current mixed voltage of automobile power cell group 2 of electricity is in full conjunction state, fuel oil Electricity generation system is stopped, and the mixed automobile of electricity relies only on electric-only mode and travelled.
With consumption of the vehicle traveling to the mixed electricity of automobile power cell group 2 of electricity, voltage progressively will synchronously decline, when electricity is mixed When the voltage of automobile power cell group 2 is less than the full conjunction value of program inner setting, system automatic start engine.Engine start Afterwards, the mixed pedal of transaxle 16 of electricity is stepped on, is started running away from start bit vehicle, then program starts to judge the mixed automobile of electricity The current voltage value of power battery pack 2, and it is provided with how many rotating speed and then output lifted for instructing engine to need in program The voltage reference value of how many generated energy, program mix the electricity detected inside the current voltage value of automobile power cell group 2 and program The voltage reference value of setting is compared, if the mixed magnitude of voltage of automobile power cell group 2 of electricity is joined less than the voltage of program inner setting Value is examined, then system automatic lifting engine speed and then lifting generator powered amount, due to the electricity warp for taking generator to send Output and the mixed parallel relationship of automobile power cell group 2 of electricity after rectification, when engine works, the mixed electricity of automobile power cell group 2 of electricity Pressure is equal to the voltage that generator is sent, and as generator power output increases, then the voltage synchronous of the mixed automobile power cell group 2 of electricity carries Rise.
As engine speed is lifted, when generating voltage lifting is arrived in the range of the voltage reference value of program inner setting, Then engine speed is no longer lifted, and keeps current state.If engine speed lifting is too high, cause the mixed automobile power cell group of electricity 2 voltages make motor power load reduce the mixed vapour of formation electricity naturally higher than reference value or because reducing Current vehicle travel speed The magnitude of voltage of car power battery pack 2 is higher than reference value, then system reduces throttle automatically, reduces engine speed, and then reduce and generate electricity Voltage.
In summary, in the process of moving, system commander's throttle lifting is the mixed automobile of electricity with the operation principle declined：Electricity is mixed Voltage lifts naturally when the electricity of automobile power cell group 2 height changes, and motor power consumption increase voltage declines naturally, electricity consumption The reduction voltage of amount rises naturally, and when generating electricity can not meet motor electricity consumption, voltage reduces naturally, and generating electricity exceedes During motor power consumption, generating voltage raises naturally.Using these three parallel principles, system is by monitoring the mixed automobile of current electricity The voltage of power battery pack 2 is improved compared with the reference value under each different condition of setting in program by engine speed Increase generated energy and then increase generating voltage, engine speed reduces automatic reduction generated energy, and then reduces generating voltage, realizes Engine speed with the change of dynamic motor power consumption, is completed to automatically control all the time.
It should be noted that the change of the present invention according to the mixed voltage of automobile power cell group 2 of electricity controls engine Synchronization changes, and realizes that Automated condtrol is only used as a kind of embodiment, can also be in motor in the control device Front end increases by one group of current transformer, one current pickup circuit of increase in signal processing module 03, realizes by monitoring pair Power consumption of the engine speed with moving motor is completed than electric current, realizes this method.
It is mutual that one group of electric current can also be increased respectively in the output end of the front end of motor, the mixed automobile power cell group 2 of electricity Sensor, two current pickup circuits of increase in signal processing module 03, realize by monitoring contrast generating, electricity consumption, charging three Electric current between person completes power consumption of the engine speed with moving motor, realizes this method.
In the oil-fired power generating system course of work, the electricity that generator is sent is except meeting that electricity mixes the electricity consumption of automobile drive electric motor Outside, can also produce a part of rich electric energy to charge for the mixed automobile power cell group 2 of electricity, with the extension in charging interval, when electricity is mixed The magnitude of voltage of automobile power cell group 2 higher than the mixed voltage of automobile power cell group 2 of electricity satisfy conjunction value when, then system is closed and started automatically Machine, reach the effect more saved.
Functional switch 18 is opened, if air-conditioning switch 13 is opened, oil-fired power generating system is in automatic air condition pattern, automatic empty When mode transfer formula works, if the mixed transaxle 16 of electricity is without acceleration and is in original position, engine keeps air-conditioning state Under highest idling mode, no longer perform engine normal idling, in order to avoid when there is air-conditioning unlatching due to load increase, use The normal idling of engine is low to be caused to be short of power and stop working.Under automatic air condition pattern, if the mixed electricity of automobile power cell group 2 of electricity Deficiency, its whole work process is identical with automatic mode operation process, and engine power generation rotating speed during automatic mode operation is higher than Air-conditioning rotating speed, generally, engine power generation rotating speed be 3000~3500 revs/min, now, rotating speed used in air-conditioning with Engine power generation rotating speed is defined.Except that：In addition to using air conditioning mode highest idling when engine idling, when the mixed automobile of electricity When the electricity of power battery pack 2 enters saturation state, engine is no longer flame-out, when throttle leaves start bit vehicle and started running, hair Motivation rotating speed is no longer changed with the mixed voltage of automobile power cell group 2 of dynamic electricity, is not also used engine power generation rotating speed, is started Machine rotating speed is stable in air-conditioning tacho value range engine peak speed only according to the air-conditioning tachometer value set in program.Example Such as, air-conditioning tachometer value, which is set in 2200~2300, can meet the needs of air conditioner refrigerating completely, pure air-conditioning work state be formed, in air-conditioning During operation, program monitors the mixed voltage of automobile power cell group 2 of electricity at any time, once there is undertension, program is immediately Into automatic air condition mode of operation, power battery voltage switches to pure air conditioning mode again once full close.
During automatic mode operation, if air-conditioning switch 13 is not turned on, the mixed automobile of electricity passes through once entering high-speed travel state The gear signal 29 of the mixed automobile gearbox high gear of electricity inputs, then system is automatically into enforced opening pattern.The mixed automobile of electricity exists In when running at a low speed, under the mixed non-full conjunction state of electricity of automobile power cell group 2 of electricity, engine throttle is with moving motor power consumption The method of work for changing and changing is identical with automatic mode.Enforced opening pattern is mainly used in high speed electric automobile, due to electronic During galloping, the delivery that motor needs is excessive, if relying only on the mixed automobile power cell group 2 of electricity meets current need Will, then easily there is the mixed over-discharge of automobile power cell group 2 of electricity, cause battery damage or battery life serious curtailment. In order to distinguish the engine power generation working condition of force start pattern and automatic mode in program, there is by force special setting in program Cut-in voltage value processed is that the electricity described in program flow diagram mixes the high-voltage value of automobile power cell group 2, the mixed automobile power cell group 2 of electricity High-voltage value automobile power cell 2 low voltage values of group more mixed than electricity are higher, and engine operationally uses high-voltage value, electrokinetic cell For group high-voltage value in addition to distinguishing the working condition of enforced opening pattern, main is to make generator provide more electricity to meet The needs that electric automobile is run at high speed.Unlike：The mixed automobile of electricity is once enter enforced opening pattern, and no matter electricity mixes automobile power Whether the voltage of battery pack 2 meets the entry condition of engine, then system automatic start engine；And enter fuel electric generator State of charge occurred frequently, now, the mixed automobile drive electric motor of electricity are no longer driven based on the electric energy of the mixed automobile power cell group 2 of electricity It is dynamic, rely primarily on the electricity that generator is sent and be driven, avoid the mixed automobile power cell group 2 of electricity from being made because overdischarge rate is excessive Into life-span it is too short or damage；Electricity mixes automobile in the process of moving, once lower-speed state in speed entrance, then system automatic switchover For automatic mode, automatic mode is changed with enforced opening pattern according to the gear signal 29 of speed height.
In the course of the work, stop generating electricity exporting by the use of engine misses is used as system protection function to system.Worked Cheng Zhong, once occur because the connecting line open circuit of power battery pack causes generating voltage superpressure or generator phase shortage, line, rectification mould Block damage causes generating electricity abnormal, then system automatically controlled engine stops working, and is protected and exports malfunction coefficient.
The present invention need not often pay close attention to the electricity of the mixed automobile power cell group 2 of electricity.The electricity of the mixed automobile power cell group 2 of electricity Pressure is stored within voltage range set in advance all the time.The phenomenon of power battery pack power shortage will not occur.Both greatly prolonged dynamic The service life of power battery pack, continuation of the journey demand is disclosure satisfy that again.Install electricity generation system additional on pure electric automobile and form the mixed automobile of electricity, Solve that pure electric automobile course continuation mileage is limited, vehicle can not be just caused by the factor such as power failure when charge power supply does not possess or charge The technological deficiency often gone on a journey.Also solve pure electric automobile installation air-conditioning and then have a strong impact on course continuation mileage, led if not installing air-conditioning additional It is too high or too low for temperature in cause driver's cabin, the technical problem of user's request can not be met.Compared with fuel-engined vehicle, both reduce out Row expense, has saved the energy again, has reached the air-conditioning effect of current automobile, improves the satisfaction of client, meets user's Demand, the important technology route of current national low-carbon environment-friendly also it has been in response to.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, this area is common Other modifications or equivalent substitution that technical staff is made to technical scheme, without departing from technical solution of the present invention Spirit and scope, all should cover among scope of the presently claimed invention.
