Strong preheating: when the working condition of the engine is in a pseudo idle working condition, the condition that the intake air is heated and started is called strong preheating.
According to an aspect of an embodiment of the present invention, an engine start control method is provided, and optionally, as an alternative implementation, the engine start control method may be applied, but is not limited to, in an application environment as shown in fig. 1.
As shown in FIG. 1, a user 102 may interact with a vehicle device 104. The in-vehicle device 104 includes a memory 106 and a processor 108. Human-computer interaction between the user 102 and the in-vehicle device 104 is possible. The vehicle-mounted device 104 includes a human-computer interaction screen, a memory 106 and a processor 108. The man-machine interaction screen is used for presenting the working state of the engine; the memory 106 is used for storing the ambient temperature of the engine, the temperature of the engine water, the running state of the engine and the change rate of the rotating speed, and acquiring the voltage of a power supply device for driving the engine to start. The processor 108 is configured to obtain an ambient temperature of the engine, a water temperature of the engine, and a voltage of a power supply device that drives the engine to start; acquiring the running state of the engine and the rotating speed change rate of the engine in a preset time period; and when the ambient temperature, the engine water temperature, the voltage, the running state and the rotating speed change rate all meet preset conditions, determining that the engine is in a pseudo idle working condition, and performing air inlet heating operation on the engine.
Alternatively, the above-described in-vehicle device 104 may be an in-vehicle device equipped with an engine start control client, and the target client may be a video client, an instant messaging client, a browser client, an education client, or the like. The above is only an example, and this is not limited in this embodiment.
In the related art, under a low-temperature environment, the external friction resistance born by the engine is particularly large, especially the engine matched with an automatic gearbox, so that the rotating speed of the engine is kept unchanged or slowly increased for a long time after the engine reaches a certain higher rotating speed in a starting stage, poor combustion in an engine cylinder is caused, and the starting performance and the emission performance of the engine are seriously influenced.
In order to solve the above technical problem, as an alternative embodiment, as shown in fig. 2, the engine start control method includes:
s202, acquiring the environment temperature and the water temperature of the engine, and acquiring the voltage of a power supply device for driving the engine to start;
s204, acquiring the running state of the engine and the rotating speed change rate of the engine in a preset time period;
and S206, when the environment temperature, the engine water temperature, the voltage, the running state and the rotating speed change rate all meet preset conditions, determining that the engine is in a pseudo idle working condition, and performing air inlet heating operation on the engine.
In step 202, during actual application, the ambient temperature and the engine water temperature of the current vehicle engine are obtained through an on-board temperature sensor, and the voltage of the power supply device driving the engine to start is obtained through a voltage detector. Here, the power supply device during the starting process includes, but is not limited to, a storage battery, which has a large capacity loss, and needs to monitor the battery voltage from time to time.
In step 204, in actual application, an Electronic Control Unit (ECU) is used to obtain a current engine operating state, where the engine operating state needs to be a starting state all the time, and simultaneously monitor that a rotation speed change rate Δ n of the engine within a certain time range is lower than a certain set rotation speed change rate, where Δ n = the current engine rotation speed — the previous step of the engine rotation speed.
In step 206, during actual application, when the ambient temperature, the engine water temperature, the voltage, the operating state and the rotation speed change rate all satisfy preset conditions, after the engine is determined to be in the pseudo idle condition, the engine is subjected to an intake air heating operation, where the intake air heating operation includes activating a strong preheating function.
In the embodiment of the invention, the ambient temperature and the water temperature of the engine are obtained, and the voltage of a power supply device for driving the engine to start is obtained; acquiring the running state of the engine and the rotating speed change rate of the engine in a preset time period; in the method, because the 'pseudo idle working condition' in the starting stage can be judged according to the conditions of monitoring the air inlet temperature, the engine rotating speed, the battery voltage and the like, whether the air inlet heating function is started or not is further determined, the purposes of improving the air inlet temperature, improving the in-cylinder combustion, rapidly improving the engine rotating speed and improving the low-temperature starting performance are achieved, and the technical problem of poor starting performance of the engine in the low-temperature environment is solved.
In one or more embodiments, the engine start control method further includes:
stopping an intake air heating operation of the engine when any one of the ambient temperature, an engine water temperature, a voltage, an operation state, and the rotation speed change rate does not satisfy the preset condition.
Specifically, for example, when the engine operating state is no longer the starting state (Cranking), such as switching to the engine Running state, the strong warm-up function is immediately exited at this time; when the working condition of the engine is not in a pseudo idle working condition any more, the strong preheating function is immediately quitted; when the strong preheating time exceeds a certain time, the strong preheating function is immediately quitted; when the battery voltage is lower than a certain limit value in the starting process of the engine, the strong preheating function needs to be immediately quitted; in summary, when at least one of the above conditions is satisfied, the strong preheat cannot be entered and should be immediately exited or turned off. Through the technical means, the embodiment of the invention fully considers the application scene of strong heating, prevents misoperation and influences on normal engine starting operation.
In one or more embodiments, the engine start control method further includes: and when any one of the ambient temperature, the engine water temperature, the voltage, the running state and the rotating speed change rate does not meet the preset condition, not starting the intake air heating operation of the engine.
Specifically, the strong warm-up function is prohibited from being turned on, for example, when the ambient temperature at which the engine is located or the engine water temperature does not satisfy the respective set thresholds.
In one or more embodiments, the ambient temperature, the engine water temperature, the voltage, the operating state, and the rate of change of the rotational speed all satisfy preset conditions including:
the temperature of the environment where the engine is located is lower than a first temperature threshold, and the temperature of the engine water is lower than a second temperature threshold; and
the voltage is higher than a preset voltage threshold, the operating state is a starting state, and the rotating speed change rate is lower than a preset rotating speed change rate.
And detecting that the ambient temperature is lower than a set temperature threshold value, and meanwhile, the water temperature of the engine is lower than a set water temperature threshold value.
In one or more embodiments, the engine start control method further includes:
determining a heating time of the intake air heating operation according to a rotation speed of the engine; wherein the heating time is inversely proportional to the rotational speed.
Specifically, when the rotation speed of the engine is far greater than the preset rotation speed, the rotation speed of the engine can be inferred to rapidly rise, the heating time of the intake air heating operation can be shortened, when the rotation speed of the engine is not greatly different from the preset rotation speed, the rotation speed of the engine can be inferred not to be obviously changed, and the heating time of the intake air heating operation can be correspondingly increased.
In one or more embodiments, the determining the heating time of the intake air heating operation according to the rotation speed of the engine includes:
acquiring the heating time of the intake air heating operation from a heating schedule according to the current rotating speed of the engine; wherein the heating time table comprises a mapping relation corresponding to the heating time and the rotating speed.
Specifically, the corresponding mapping relation between the heating time and the rotating speed is stored in the heating time table, and the ECU acquires the corresponding heating time of the air inlet heating operation from the heating time table by determining the rotating speed of the current engine, so that the air inlet heating can be intelligently and conveniently controlled, and the cold starting performance of the engine is improved.
In one or more embodiments, the engine start control method further includes: and when the intake air heating operation exceeds a preset heating time period or the engine is determined to be in an idling state from the pseudo-idling working condition, stopping the intake air heating operation of the engine.
In the embodiment of the invention, when the intake air heating operation time is too long and the rotating speed of the engine is not changed greatly, the engine possibly breaks down at the moment, and the intake air heating operation on the engine is automatically stopped, so that the damage to the engine is avoided; in addition, the electronic control unit ECU judges that the rotating speed change rate of the engine is larger than the preset rotating speed change rate, the engine is turned to an idling state from the pseudo-idling condition, and the air intake heating operation of the engine is automatically stopped.
In one or more embodiments, the performing an intake air heating operation on the engine includes:
the air flowing through an intake air heater is heated by controlling the intake air heater by an electronic control unit based on the intake air heater disposed in an intake pipe of an engine.
During engine starting, a large amount of battery energy is usually consumed to ensure a sufficiently high speed during the starter pull phase, and intake air heating is usually turned off to reduce battery consumption. According to the embodiment of the invention, the air inlet heating function of the engine is controlled to be started by judging the 'pseudo idle working condition' in the starting stage of the engine, so that the air inlet temperature is rapidly increased.
In one embodiment, as shown in fig. 3 and 4, the engine start control method further comprises the following steps:
1. strong preheating activation
1. According to the scheme, whether an external condition meets an activation requirement is judged, firstly, the environment temperature is detected to be lower than a set temperature threshold (EnvT _ t < EnvT _ Limt), and meanwhile, the water temperature of an engine is lower than a set water temperature threshold (CEngDsT _ t < CEngDsT _ Limt);
2. the capacity of the storage battery is greatly lost in the starting process, the voltage of the storage battery needs to be monitored at any time, and the voltage of the storage battery in the starting process is required to be higher than a set value of the voltage of the storage battery (Battu _ u is more than Battu _ uSet _ Limt);
3. secondly, detecting whether the running state of the engine changes or not, wherein the running state of the engine needs to be always in a starting state (CoEng _ st = Cranking);
4. the most important thing in this scheme is to accurately detect that the engine operating condition is in a "pseudo idle operating condition", that is, the engine speed is in a certain time range (StSys _ tifalseldelchlhk _ C), and detect that the rate of change of the engine speed Δ N (rate of change of the engine speed Δ N = the current engine speed — the last step of the engine speed) is lower than a certain set speed limit (Δ N _ SetEng).
As shown in fig. 3 below, the above conditions need to be satisfied simultaneously, and strong warm-up (intake air heating function) is enabled. At the moment, the intake air heating function is activated aiming at the 'pseudo idle working condition', the heating time is obtained by looking up a time table, the length of the heating time is set according to the variation range of the rotating speed of the engine, if the deviation of the rotating speed of the engine is smaller, the engine can be in the 'pseudo idle working condition' for a long time, and the required heating time is longer, so that the intake air temperature is further increased; if the deviation of the engine speed is larger, the engine speed is indicated to have rapidly increased, and the required heating time is shorter.
2. Strong preheat exit and shutdown
1. When the ambient temperature or the water temperature of the engine does not meet respective set thresholds, the strong preheating function cannot enter;
2. when the Running state of the engine is not the starting state (Cranking), if the Running state of the engine is switched to the Running state of the engine, the strong preheating function is immediately exited;
3. when the working condition of the engine is not in a pseudo idle working condition any more, the strong preheating function is immediately quitted;
4. when the strong preheating time exceeds a certain time, the strong preheating function is immediately quitted;
5. when the battery voltage is lower than a certain limit value in the starting process of the engine, the strong preheating function needs to be immediately quitted;
when at least one of the above conditions is satisfied, the strong preheat cannot be entered, and should be immediately exited or shut down. The application scene of strong heating is fully considered, misoperation is prevented, and normal engine starting operation is prevented from being influenced.
The embodiment of the invention also has the following beneficial technical effects:
1. judging the activation condition of strong preheating through complex and strict boundary conditions to prevent entering strong heating by mistake;
2. strict constraint conditions are provided for judging the pseudo idle working condition;
3. after entering the strong preheating, if the corresponding condition is not satisfied, the strong preheating can be immediately exited, clear requirements are provided for exiting and closing the strong preheating, the situation that the strong preheating function cannot be exited or closed in time is avoided, and the effect of intelligently switching whether the strong preheating works in the starting stage is achieved.
