In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
For ease of understanding and describing succinct, be hereafter described in conjunction with motor car engine warming up controlling method and device, beneficial effect no longer repeats to discuss.
Please refer to Fig. 2, Fig. 2 is the flow chart of motor warming up controlling method in specific embodiment.
The motor warming up controlling method that the present embodiment provides comprises the following steps:
S11, storage list levy warming-up calibration value corresponding to each parameter of engine operating condition, engine condition and ambient condition;
Under S12, acquisition current state, characterize each current parameter value of engine operating condition, engine condition and ambient condition;
S13, be all less than corresponding warming-up calibration value for warm-up condition with each current parameter value, the aperture according to present engine regulating working conditions EGR valve 106 carries out warming-up;
S14, treat that present engine temperature exceeds default engine temperature, warming-up completes.
If it is pointed out that, warm-up condition does not meet, then the aperture of EGR valve 106 operates according to the logic under motor normal operating condition; After warming-up completes, the logic that the aperture of EGR valve 106 also returns under normal operating condition operates.
The present embodiment provides engine warm truck control device, and this device comprises following parts:
Storage unit, levies warming-up calibration value corresponding to each parameter of engine operating condition, engine condition and ambient condition for storage list.
Acquiring unit, under obtaining current state, characterizes each current parameter value of engine operating condition, engine condition and ambient condition.
Judge performance element, be all less than corresponding warming-up calibration value for warm-up condition with each current parameter value, the aperture according to present engine regulating working conditions EGR valve 106 carries out warming-up, until present engine temperature exceeds default engine temperature.
As above, the method and apparatus that the present embodiment provides, egr system is utilized to realize rapid warming-up, due under motor normal operating condition, the cooler for recycled exhaust gas 105 of egr system utilizes engine coolant to cool the waste gas of recirculation, so when motor needs warming-up, the temperature that waste-gas heat can be utilized conversely to promote cooling liquid realizes warming-up.Particularly, in this programme, with engine operating condition, engine condition and ambient condition for monitoring target, when it meets warm-up condition, regulated by the aperture of EGR valve 106, control the exhaust gas flow by cooler for recycled exhaust gas 105, utilize the temperature of the heat lift engine coolant of waste gas, accelerate warming-up process.
Compared with prior art, the method and device evaded by close exhaust braking valve realize warming-up, thus avoid pressurization system (as the pressurized machine 104 in Fig. 1, intercooler 103) is impacted, it also avoid and the component such as EGR valve 106 and cooler for recycled exhaust gas 105 are impacted; Meanwhile, also avoid that to close the motor caused passive flame-out because of exhaust braking valve.
In concrete scheme, the parameter characterizing engine operating condition is rotating speed and fuel injection quantity; The parameter characterizing engine condition is coolant temperature; The parameter of representing ambient state is ambient temperature.
Warming-up calibration value corresponding to above-mentioned each parameter can be obtained by the mode tested or emulate in advance.
Further, be reaction environment state more accurately, during representing ambient state, also can be aided with external pressure on the basis of ambient temperature.In reality, external pressure is basically identical, but under some particular surroundingss (as altitude environment), external pressure can change to some extent, also certain influence can be produced to motor the need of warming-up, ambient temperature and external pressure are combined and characterizes ambient condition, warming-up can be controlled more accurately.
Further, for reacting engine condition more accurately, when characterizing engine condition, also oil temperature can be aided with on the basis of coolant temperature.
In reality, be also feasible with coolant pressure, fuel level indicator motivational state of levying.Certainly, also can characterize engine condition with other parameters (as fuel oil temperature etc.), in contrast, cooling liquid and machine oil state more typical, can be used as preferably.
Usually, motor is inherently provided with sensor or the computing module of the correspondence detecting or calculate above-mentioned each characterization parameter, so in concrete scheme, the real-time parameter value of above-mentioned each characterization parameter can utilize existing sensor to detect and obtain (as engine speed, coolant temperature etc.), or carries out calculating acquisition (fuel injection quantity as motor) according to associated arguments by existing computing module.
More specifically, the ECU of motor can be utilized realize, ECU (ElectronicControl Unit, electronic control unit) also known as car running computer, vehicle-mounted computer etc., aforementioned storage unit, acquiring unit and judge that performance element all can be built in ECU.
Usually, engine temperature refers to coolant temperature, and warming-up whether success is also main with reference to coolant temperature, so in preceding method and device, is greater than default coolant temperature can thinks that warming-up completes as long as monitor coolant temperature.
It is pointed out that as can be seen from aforementioned method steps, when judging whether to need warming-up, coolant temperature is also as a reference quantity, so when in fact arranging, the warming-up calibration value of coolant temperature and default coolant temperature are two different storing values.
Composition graphs 3, Fig. 3 is the logic diagram of engine warm car condition judgment in specific embodiment.
Present engine operating mode judges:
Speed probe detects engine speed, and ECU can calculate present engine fuel injection quantity in real time; Detect that the current rotating speed of motor is less than the rotating speed warming-up calibration value stored in ECU, and when the current fuel injection quantity calculated also is less than the fuel injection quantity warming-up calibration value stored in ECU, present engine operating mode meets warm-up condition.
Here it should be noted that, engine operating condition is not confined to idling operation herein, as long as meet the working condition (as 1000r/min, 100mg/hug) demarcated.
Present engine condition adjudgement:
Engine coolant temperature sensor detects coolant temperature in real time, and engine motor oil temperature transducer detects engine oil temperature in real time; Detect that the current coolant temperature of motor is less than the coolant temperature warming-up calibration value stored in ECU, and when detecting that the current oil temperature of motor is also less than the oil temperature warming-up calibration value stored in ECU, present engine state meets warm-up condition.
Current ambient conditions judges:
The real-time testing environment temperature of environment temperature sensor, the real-time testing environment pressure of ambient pressure sensor; The current environmental temperature detected is less than the ambient temperature warming-up calibration value stored in ECU, and when the current environment pressure detected also is less than the external pressure warming-up calibration value stored in ECU, current ambient conditions meets warm-up condition.
It is to be noted, because current OBD laws and regulations requirement can not carry out the supervision of discharging when the temperature of the surroundings is low, thus by this Rule of judgment arrange rationally, effectively can evade warming up time EGR valve 106 open the discharge caused and to decline the OBD warning problem caused.
When above-mentioned engine operating condition, engine condition and ambient condition all meet warm-up condition, just start to carry out warming-up.
During warming-up, regulate the aperture of EGR valve 106, control the exhaust gas flow by cooler for recycled exhaust gas 105, control the lifting to engine coolant temperature.
In concrete scheme, can set up the MAP corresponding to EGR valve 106 aperture of working conditions of different engines and store, that is, the storage unit of described device also stores the MAP of EGR valve 106 aperture corresponding to working conditions of different engines.
Certainly, engine operating condition also characterizes with rotating speed and fuel injection quantity here.
It should be noted that, based on different type of machines, the MAP formed is also different.
When warm-up condition is set up, when needing to carry out warming-up, can search the described MAP be stored in ECU according to current engine operating condition, obtain the aperture with the EGR valve 106 of present engine Conditions Matching, and regulate with this.
Here it should be noted that, during warming up, different EGR valve 106 aperture settings can be carried out to different operating modes by arranging of MAP, thus situation bad under preventing some operating modes occurs, as under idling operation, for avoiding because EGR valve 106 opens the problem such as idle stability decline, car load vibration caused, the EGR valve 106 of this idling operation point can be demarcated as not opening or aperture very little.

S15, generation warming-up success status message, and transmitted by CAN;
S16, motormeter are caught warming-up success status message from CAN and are shown.
Correspondingly, described device also comprises warm-up mode message generation unit, with after warming-up completes, generates warming-up success status message, and is transmitted by CAN, caught and show by motormeter.
Particularly, motormeter can by the mode of bright light, or the mode of language, or the mode of word shows warming-up success status.
So, motormeter can show the successful state of warming-up and point out driver, so that driver carries out subsequent operation, avoids excessive warming-up to cause waste.
Please refer to Fig. 5, Fig. 5 is the schematic diagram that under certain operating mode, different EGR valve aperture affects warm-up period.
As shown in Figure 5, under certain operating mode, 85 DEG C are reached for warming-up target with engine temperature, EGR valve 106 aperture for 60% time warming-up needed for time be significantly less than EGR valve 106 aperture for 0 time warming-up needed for time, visible by egr system, utilize high-temp waste gas to heat coolant temperature, effectively can shorten warm-up period, thus reduce mechanical friction, the reduction oil consumption of motor, improve utilization efficiency and the reliability of motor.
