Judging unit 2, receives described multiple vehicle operating parameters and compares with the corresponding vehicle operating parameters threshold value preset respectively, and judge the preheat mode residing for described vehicle according to comparative result;
Reminding unit 3, sends the alerting signal corresponding with the preheat mode residing for vehicle to user.Particularly, described alerting signal can be light or voice mode.
Particularly, described judging unit 2 is preset with threshold engine speed, engine coolant temperature threshold value, crankcase oil temperature threshold and transmission oil temperature threshold.
Described preheat mode specifically can comprise idling preheating completion status and low speed preheating completion status, further can also comprise idling preheat mode and low speed preheat mode, to provide more detailed preheat mode to user.Certainly, only to user provide idling preheating completion status and low speed preheating completion status also enough users obtain and start vehicle and started the normal appropriate opportunity travelled.
Particularly, before described judging unit 2 is arranged in vehicle start, when comparative result meets first condition, then judge that described vehicle is in idling preheating completion status.Wherein, described first condition comprises that described engine speed is less than or equal to threshold engine speed, described engine coolant temperature is more than or equal to engine coolant temperature threshold value and described engine lubrication oil temperature is more than or equal to crankcase oil temperature threshold.Described judging unit 2 is after vehicle launch and when not reaching idling preheating completion status, judge that described vehicle is in idling preheat mode.
Particularly, described judging unit 2 is arranged in vehicle and is in described idling preheating completion status and after vehicle start, when comparative result meets second condition, then judges that described vehicle is in described low speed preheating completion status; Described second condition comprises described transmission oil temperature and is more than or equal to transmission oil temperature threshold.Described judging unit 2, when vehicle is in idling preheating completion status and does not reach described low speed preheating completion status after vehicle start, judges that described vehicle is in low speed preheat mode.
Described judging unit 2 is after obtaining preheat mode, and the preheat mode reached by vehicle by reminding unit 3 is supplied to user with the form of sound or light, makes user know the preheat mode of vehicle in time.Such as, " low speed preheating completes " or " idling preheating completes " can be played to user in the mode of voice; Or different preheat modes can also be corresponded to different lamp colrs, make user can know preheat mode according to lamp colr.
Further, described device is opened automatically when vehicle motor starts, and automatically closes to save energy consumption after reminding user can enter normal motoring condition.
Figure 2 shows that the diagram of circuit of vehicle preheating based reminding method, specifically comprise the steps:
Step 101, after the engine started, the multiple vehicle operating parameters of Real-time Obtaining; Particularly, described multiple vehicle operating parameters can comprise engine speed, engine coolant temperature and engine lubrication oil temperature;
Step 102, judge whether described engine speed is less than or equal to described threshold engine speed, whether described engine coolant temperature is more than or equal to described engine coolant temperature threshold value and whether described engine lubrication oil temperature is more than or equal to described crankcase oil temperature threshold, be continue step 103, otherwise continue step 104;
Step 103, the preheating of reminding user vehicle idling completes, can enter low-speed running state, then enter step 105;
Step 104, reminding user vehicle is in idling preheat mode, then continues step 102; Idling preheat mode can be in without reminding user vehicle in another embodiment, directly return step 102;
Step 105, after vehicle start, Real-time Obtaining transmission oil temperature; In another embodiment, step 105 can be omitted; When obtaining multiple vehicle operating parameters in a step 101, transmission oil temperature is obtained as one of them vehicle operating parameters;
Step 106, judges whether described transmission oil temperature is more than or equal to described transmission oil temperature threshold, is continue step 107, otherwise continues step 108;
Step 107, the preheating of reminding user vehicle low speed completes, can enter normal motoring condition;
Step 108, reminding user vehicle is in low speed preheat mode, then continues step 106; In another embodiment, low speed preheat mode can be in without reminding user vehicle, directly return step 106.
Can time carry out reminding user vehicle preheat mode by the mode of sound or light so that user can adjust driving condition timely according to vehicle preheat mode, avoid causing damage because preheating is insufficient to vehicle.On the other hand user can know vehicle preheat mode timely, can start vehicle in time when vehicle completes idling preheating, to avoid because vehicle preheating time is long consumed energy in vain, it also avoid and lose time.
Above embodiment only for illustration of technical scheme of the present invention, is not limited to protection scope of the present invention.The amendment that those skilled in the art can carry out technical scheme of the present invention or replace on an equal basis, and do not depart from the spirit and scope of technical solution of the present invention.
