Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Describe the monitoring method of cooling fan motor of the vehicle proposed according to the embodiment of the present invention and supervisory system with reference to the accompanying drawings and there is the vehicle of this supervisory system.
First the monitoring method of the cooling fan motor of the vehicle of the embodiment of the present invention is described.Wherein, vehicle comprises engine management system, and the cooling fan motor of vehicle comprises main fan motor and secondary fan electromotor.
Fig. 2 is the flow chart of the monitoring method of the cooling fan motor of vehicle according to an embodiment of the invention, and as shown in Figure 2, this monitoring method comprises the following steps:
S1, engine management system transmits control signal main fan motor and/or secondary fan electromotor are run according to control signal.
Such as, according to cooling requirements, when engine management system (EMS) sends fan low-speed running signal Fan Low, the adhesive of low speed cooling fan relay, main fan motor is at low speed; When EMS transmission fan runs up signal Fan High, high speed fan relay and the adhesive simultaneously of secondary cooling fan relay, main fan motor runs up, secondary fan motor runs.EMS realizes the control to the cooling fan motor of vehicle.
S2, engine management system receives the feedback signal of main fan motor and/or secondary fan electromotor respectively, and judges whether main fan motor and/or secondary fan electromotor normally run respectively according to feedback signal and control signal.
Such as, when main fan motor is at low speed, EMS receives the feedback signal such as feedback voltage signal of main fan motor simultaneously, and then EMS judges whether feedback voltage signal meets the requirement sending control signal, namely feedback voltage level is judged whether within the scope of the normal working voltage that control signal is corresponding, if feedback signal normally, shows that main fan machine operation is normal, if instead feedback signal is abnormal, then show that main fan machine operation is abnormal, thus the monitoring of the running state to main fan motor can be realized, for safe driving provides basis.
Again such as, main fan motor run up and secondary fan motor runs time, EMS receives the feedback signal of main fan motor and secondary fan electromotor respectively, and judge the normal working voltage scope of feedback signal whether corresponding control signal, if feedback signal is normal, then show main fan motor and secondary fan electromotor working properly, if feedback signal is abnormal, judge main fan motor and/or secondary fan electromotor work abnormal, thus the monitoring of the running state to main fan motor and secondary fan electromotor can be realized, for safe driving provides basis.
Can find out, the monitoring method of the cooling fan motor of the vehicle of the embodiment of the present invention, transmit control signal that cooling fan motor is controlled by engine management system, and receive the feedback signal of cooling fan motor, and then judge that whether cooling fan motor work is normal according to feedback signal and control signal, thus the monitoring realized cooling fan state, for safe driving provides basis.
Wherein, according to feedback signal and control signal, the whether normal process of cooling fan motor work is judged for EMS, particularly, EMS judges whether feedback signal is in the threshold range corresponding with the control signal that EMS sends, if feedback signal is in threshold range, then engine management system judges that main fan motor and/or secondary fan electromotor normally run.
In one embodiment of the invention, as shown in Figure 3, be the deviation range curve synoptic diagram of feedback signal (feedback voltage) under different duty control signal.Wherein, Umax and Umin is respectively the cooling fan motor maximum value of feedback signal and minimum value under normal circumstances, exceeds this threshold range and is then considered as operation irregularity state.Such as, EMS sends 95% duty cycle control signal, main fan motor is at low speed, the feedback signal of the main fan motor that EMS receives is magnitude of voltage a, if between the maximum value that a is in feedback voltage corresponding to 95% dutycycle and minimum value, then judge that main fan machine operation is normal, otherwise judge that main fan machine operation is abnormal.Similarly, when main fan motor and secondary fan electromotor are all operated, EMS receives the feedback signal of main fan motor and secondary fan electromotor respectively, and judge respectively the feedback signal that receives whether normal with judge main fan motor and secondary fan electromotor work whether normal.
Further, if EMS judges that feedback signal is abnormal, the threshold range that Umax and Umin that namely if feedback signal exceeds Normal Feedback signal corresponding to control signal limits, then enter warning reminding functional mode, such as, engine management system controls the drop engine speed of vehicle to preset rotation speed, and namely motor reduces rotating speed, and then the speed of a motor vehicle reduces, to ensure driving safety.
If feedback signal exceeds threshold range corresponding to control signal, engine management system also sends the combination instrument of cue to vehicle to point out.Such as, warning light useful signal is sent to combination instrument by the CAN of vehicle by EMS, and then combination instrument directly lights the abnormal mark of fan, thus driver's cooling fan motor can be reminded abnormal, takes measures as early as possible, avoids occurring danger.
In sum, the monitoring method of the cooling fan motor of the vehicle of the embodiment of the present invention, traditional control system increases the feedback signal receiving main fan motor and secondary fan electromotor, whether the working state monitoring cooling fan motor at any time performs according to control signal, fault is avoided to occur, for safe driving provides basis.In addition, when judging cooling fan operation irregularity, being pointed out by the combination instrument of vehicle, reminding driver to take corresponding solution, and controlling drop engine speed and then vehicle reduction of speed, avoiding causing danger.

Engine management system 40 transmits control signal the break-make controlling the first main fan switch 10, second main fan switch 20 and secondary fan swicth 30, runs according to control signal to make main fan motor and/or secondary fan electromotor.Such as, according to cooling requirements, when engine management system 40 (EMS) sends fan low-speed running signal, the first main fan switch 10 closes, and main fan motor 50 is at low speed; When EMS transmission fan runs up signal, the second main fan switch 20 and secondary fan swicth 30 close simultaneously, and main fan motor 50 runs up, and secondary fan electromotor 60 operates.EMS realizes the control to the cooling fan motor of vehicle.
After cooling fan motor starts, EMS receives the feedback signal of main fan motor 50 and/or secondary fan electromotor 60, such as, in Fig. 4, EMS is connected main fan motor 50 and secondary fan electromotor 60 with the feedback signal Secondary Fan F/B of the feedback signal Main Fan F/B and secondary fan electromotor 60 that accept feedback signal and main fan motor 50 respectively respectively by signaling line 1 and signaling line 2, and judges whether main fan motor 50 and/or secondary fan electromotor 60 normally run respectively according to feedback signal and control signal.Such as, when main fan motor 50 is at low speed, EMS receives the feedback signal such as feedback voltage signal of main fan motor 50 simultaneously, and then EMS judges whether feedback voltage signal meets the requirement sending control signal, namely feedback voltage level is judged whether within the scope of the normal working voltage that control signal is corresponding, if feedback signal normally, shows that main fan motor 50 is working properly, otherwise, if feedback signal is abnormal, then show that main fan motor 50 works abnormal, thus the monitoring of the running state to main fan motor 50 can be realized, for safe driving provides basis.
Again such as, when main fan motor 50 runs up and secondary fan electromotor 60 operates, EMS receives the feedback signal of main fan motor 50 and secondary fan electromotor 60 respectively, and judge the normal working voltage scope of feedback signal whether corresponding control signal, if feedback signal is normal, then show main fan motor 50 and secondary fan electromotor 60 working properly, if feedback signal is abnormal, judge that main fan motor 50 and/or secondary fan electromotor 60 work abnormal, thus the monitoring of the running state to main fan motor 50 and secondary fan electromotor 60 can be realized, for safe driving provides basis.
Can find out, the supervisory system 100 of the cooling fan motor of the vehicle of the embodiment of the present invention, transmit control signal that cooling fan motor is controlled by engine management system 40, and receive the feedback signal of cooling fan motor, and then judge that whether cooling fan motor work is normal according to feedback signal and control signal, thus the monitoring realized cooling fan state, for safe driving provides basis.
Wherein, according to feedback signal and control signal, the whether normal process of cooling fan motor work is judged for EMS, particularly, as shown in Figure 3, engine management system 40 judges whether feedback signal is in the threshold range of Umax and the Umin restriction corresponding with control signal, and when feedback signal is in threshold range, determine that main fan motor 50 and/or secondary fan electromotor 60 normally run.
Further, when feedback signal exceeds above-mentioned threshold range, then enter warning reminding functional mode, such as, engine management system 40 controls the drop engine speed of vehicle to preset rotation speed, and namely motor reduces rotating speed, and then the speed of a motor vehicle reduces, to ensure driving safety.
If feedback signal exceeds threshold range corresponding to control signal, engine management system 40 is also for sending the combination instrument of cue to vehicle to point out.Such as, warning light useful signal is sent to combination instrument by the CAN of vehicle by EMS, and then combination instrument directly lights the abnormal mark of fan, thus driver's cooling fan motor can be reminded abnormal, takes measures as early as possible, avoids occurring danger.
