Embodiment two
In the present embodiment; The Start-Stop monitoring control devices vehicle current states information (like engine speed, the speed of a motor vehicle, gear information, clutch state, braking state etc.); And judge specifically and should send the still startup command of ceasing and desisting order to driving engine (not shown among Fig. 3) according to these status informations, so that driving engine stops or starting.More than these are all realized in the prior art, repeat no more here.Different with prior art is that the Start-Stop controller of present embodiment also links to each other with the fan of on-board air conditioner, promptly can also control the switch of on-board air conditioner fan (hereinafter to be referred as fan), thereby coordinate the start and stop of driving engine and the switch of fan.Concrete, referring to shown in Figure 3, in the present embodiment, the original K switch 1 of fan constant (K1 is appreciated that and is the original physical switch of fan, for example manual control switch) is new K switch 2 of K1 series connection then.K2 is a relay switch; Its control end (or claiming input end) links to each other with the Start-Stop controller, and connect with K1 in working end (or claiming mouth), in other words; The disconnection of Start-Stop controller may command K2 is with closed, thus under the closed situation of K1 the Push And Release of control fan.
Need to prove; When K1 broke off, promptly fan was in physics closed condition (or claiming non-serviceable condition), and this moment, the Start-Stop controller can't be controlled fan; Certainly also need not control fan; Because this moment, fan was always closed condition, just can not produce the start and stop coordination problem with driving engine, so the situation when this paper only relates to the K1 closure yet.
The initial scene of present embodiment is: vehicle is at cruising, and promptly driving engine is in operative condition, and simultaneously K2 is closed, and promptly fan is in open mode, then the Start-Stop controller to the control method of fan referring to shown in Figure 2, specific as follows:
S201: obtain vehicle state information.
S202: generate driving engine start and stop instruction according to vehicle state information.S201 and S202 step are optional step in the present embodiment.The present embodiment method is used for the Start-Stop controller; But in other embodiment of the present invention; This method can also be used for other vehicle control system device equipment; So long as this system device equipment can judge automatically open or should kill engine and get final product, or can from this system device equipment get access to or intercept driving engine start and stop instruction to be sent and get final product.
If this driving engine start and stop instruction is the driving engine halt instruction, for example user's temporary term stop then gets into step S203, and S203 and subsequent step thereof are first branch of this method flow process, is used to realize that driving engine stops and the coordination of fan between closing; Otherwise; If this driving engine start and stop instruction is engine start instruction, for example the user finishes temporary term stop preparation starting, then gets into step S207; S207 and subsequent step thereof are second branch of this method flow process, are used to realize the coordination between opening of engine starting and fan.
The basic thought of first branch is:, then remove to close fan earlier, and then remove shutting engine down when being the driving engine halt instruction when to be sent, promptly before driving engine stops, closing fan earlier, thereby avoid driving engine to stop aft-fan infringement storage battery.
The basic thought of second branch is, when to be sent when being engine start instruction, and shilling engine starting then, and then make fan open, promptly delay opening the time of fan, thereby avoid the influence of fan the vehicle launch time.
S203: judge whether fan is in open mode.Judge promptly whether K2 is closed.If then get into step S204, then directly get into step S206 if not.The front has supposed that driving engine and fan all are in opening when initial in the present embodiment, so when preparing shutting engine down, can know that fan state still for opening, so this step is an optional step, can not get into.The purpose of this step is in order to raise the efficiency; For example if previous made K2 break off (being that fan cuts out) owing to certain situation (for example step on the accelerator) suddenly etc. occurs; Then can omit this moment or claim to skip below close the step (being S204) of fan, and the step (being S206) that directly gets into shutting engine down.
S204: close fan.The Start-Stop controller breaks off K2 through control relay, promptly sends out code to fan, so that fan cuts out.
S205: judge whether fan closes,, then carry out other particular processing if not, for example report an error etc. if then get into S206.This step is an optional step, and purpose is the extra fan state of checking, in case occur unusual.
S206: shutting engine down.Promptly just send the driving engine halt instruction that had before got access to this moment, so that driving engine stops to driving engine.So far, first branch finishes, and main-process stream also is through with.
S207: judge whether fan is in open mode,, then get into step S210 if not if then get into step S208.This moment, driving engine was in halted state, and can be known at driving engine by top step and fan to have cut out before stopping that promptly K2 has broken off, so this step is an optional step, can not get into.The purpose of this step is in order to make provision against emergencies, and through judging fan state extraly, verifies promptly whether K2 really is to be in off-state, improves the robustness of this method.If the genuine disconnection (being that fan is in open mode) owing to accident of K2 then also need be broken off K2 (promptly getting into S208), and then carried out the step (promptly getting into S210) of start the engine.Again for example, when the initial start-up driving engine, also can remove to judge the state of K2 earlier.
S208: close fan.This step is the subsequent step of S207, also is optional step.
S209: judge whether fan closes,, then carry out other processing if not, for example report an error etc. if then get into S210.Similar with S205, this step is an optional step, and purpose is the extra fan state of checking.
S210: start the engine.Promptly just send the engine start instruction that had before obtained this moment, so that engine starting to driving engine.
S211: open fan.The control of Start-Stop controller makes K2 closed through relay, promptly sends OPEN to fan, so that fan returns to previous open mode.So far, second branch finishes, and main-process stream also is through with.
Need to prove, specifically be that the Push And Release of on-board air conditioner fan is controlled in the present embodiment.In other embodiment of the present invention, can also carry out same control to the Push And Release of other vehicle mounted electrical apparatus, so long as this electrical equipment by the generator powered of engine drives, when driving engine is out of service by the storage battery power supply or the analogue of vehicle.
