Description
Technical field
This utility model relates to auto electric and controls technical field, particularly relates to a kind of automobile engine pre-
Hot cue circuit.
Background technology
At low ambient temperatures, electromotor is difficult to start, and pre-heating system can preheat to electromotor,
Assisted engine successfully starts up.Preheating electronic-controlled installation is then mainly by the break-make of preheating relay
Realize the control of the opening and closing to pre-heating system.In actually used, major part assembling diesel oil is sent out
The vehicle of motivation all uses preheating controller (Preheat controller) to solve Diesel engine
Cold-starting difficult problem.The control unit of the electromotor of vehicle (Electronic Control Unit,
ECU) ECT is judged by liquid temperature sensor, according to the temperature value set in program,
Such as 25 DEG C, it may be judged whether need to control the work of engine prewarming plug.When coolant temperature is less than setting
Temperature value time, electromotor ECU output one low level signal to preheating controller, make pre-thermal control
Device processed works, and heats to engine prewarming plug, light combination instrument simultaneously during preheating controller work
Pre-thermal light, when the ECU of electromotor detects that coolant temperature reaches the temperature value set in program
After, the ECU of electromotor exports a high level signal and stops work to preheating controller, preheating controller
Making, pre-thermal light extinguishes, and now can start vehicle smoothly.
As it is shown in figure 1, be the circuit diagram of pre-heater circuit in prior art, wherein 1 is the ECU of electromotor,
Fig. 1 has only marked in the ECU 1 of electromotor the binding post relevant to preheating, other binding post
Not illustrating in the drawings, 2 is pre-thermal light, and 3 is preheating controller, and 4 is liquid temperature sensor.Start
The binding post E1 of the ECU 1 of machine obtains ECT by liquid temperature sensor 4, starts
The binding post E2 of the ECU 1 of machine receives the binding post G4 input signal of preheating controller 3, sentences
Disconnected preheating controller 3 is the most normal, and the binding post E3 of the ECU 1 of electromotor controls preheating controller
3 work, during binding post E3 output low level, preheating controller 3 works, preheating during output high level
Controller 3 quits work, and the preheating of the binding post E4 control combination instrument of the ECU 1 of electromotor refers to
Show that lamp 2 is lighted or extinguishes.Its operation principle is:
When starting vehicle, first key is got to ON shelves, the binding post E2 detection of the ECU 1 of electromotor
The binding post G4 input signal of preheating controller 3 is the most normal, if preheating controller 3 being detected
Binding post G4 is that high level then determines that preheating controller 3 is for normal condition, the simultaneously ECU of electromotor
1 receives, by binding post E1, the coolant temperature signal that liquid temperature sensor 4 gathers, it may be judged whether need
Electromotor is preheated.When the temperature value set during coolant temperature is higher than program, electromotor
The pre-thermal light 2 of binding post E4 control combination instrument of ECU 1 light after extinguish immediately, this
Time can across-the-line starting vehicle.When the temperature value set during coolant temperature is less than program, electromotor
The binding post E4 output low level signal of ECU 1, to the pre-thermal light 2 of combination instrument, combines instrument
The pre-thermal light 2 of table is lighted, simultaneously the binding post E3 output low level letter of the ECU 1 of electromotor
Number give preheating controller 3 binding post G5, make preheating controller 3 work, preheating controller 3 work
When making, binding post G6, binding post G7, binding post G8, binding post G9 output high level are given
Engine prewarming plug, to engine prewarming.The now ECU 1 real-time judge liquid temperature sensor of electromotor
The coolant temperature values of 4 detections, determine when coolant temperature is higher than the temperature value in program and have preheated
Becoming, binding post E3 and E4 of the ECU 1 of electromotor all becomes high level, and preheating controller 3 stops
Only work, the pre-thermal light 2 of combination instrument extinguishes, and now can start vehicle smoothly.
But, in prior art, driver needs the pre-thermal light by combination instrument to judge that vehicle is
No can start, but the effect of the pre-thermal light of combination instrument is not known about by most of driver, causes
Situations below occurs when ambient temperature is relatively low:
1, the pre-thermal light of combination instrument does not also extinguish and just starts vehicle, and vehicle does not preheats fully, nothing
Method starts, and driver likely can be carried out continuously the action starting vehicle, causes vehicle battery seriously to lose
Electricity, also cannot start even if vehicle has normally preheated.
2, the pre-thermal light of combination instrument starts vehicle after extinguishing the most in time, causes the coolant of vehicle
Temperature reduces again, again need to preheat electromotor, but driver is out of the picture, cause vehicle without
Method normal starting, if now driver starts vehicle continuously, then can cause the serious power shortage of vehicle battery,
Even if normal condition also cannot start vehicle.
Therefore, the method only pointed out user with pre-thermal light can not meet actually used need
Asking, such as, both the above situation all can make the discharged or defective battery on vehicle serious, even if causing just
Often also cannot start vehicle under preheating completion status, need the accumulator that more renews, and accumulator
Relatively costly, vehicle use cost increases, and driver can be made to produce complaint.
