[0017] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0018] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0019] Here, the technical terms involved in the embodiments of the present invention are explained as follows:

[0020] Intake air heating: A heater installed in the intake pipe in a low temperature environment. The ECU controls the intake air heater to heat the air flowing through the heater to increase the intake temperature of the engine.

[0021] Pseudo idle condition: Due to the large friction resistance on the engine, the engine speed remains unchanged for a long time or rises slowly after reaching a certain speed during the starting phase. At this time, the engine is still in the starting process and fails to start normally.

[0022] Strong preheating: When the engine is in "pseudo idle condition" and the intake air heating is turned on, this situation is called strong preheating.

[0023] According to one aspect of an embodiment of the present invention, an engine start control method is provided. Optionally, as an optional implementation, the engine start control method can be but is not limited to being applied to: Figure 1 In the application environment shown.

[0024] like Figure 1As shown, human-computer interaction can be performed between the user 102 and the vehicle-mounted device 104. The vehicle-mounted device 104 includes a memory 106 and a processor 108. Human-computer interaction can be performed between the user 102 and the vehicle-mounted device 104. The vehicle-mounted device 104 includes a human-computer interaction screen, a memory 106 and a processor 108. The human-computer interaction screen is used to present the working state of the engine; the memory 106 is used to store the ambient temperature of the engine, the engine water temperature, the engine running state and the speed change rate, and to obtain the voltage of the power supply device that drives the engine to start. The processor 108 is used to obtain the ambient temperature of the engine, the engine water temperature, and the voltage of the power supply device that drives the engine to start; obtain the running state of the engine and the speed change rate of the engine within a preset time period; when the ambient temperature, the engine water temperature, the voltage, the running state and the speed change rate all meet the preset conditions, it is determined that the engine is in a pseudo-idle condition, and the intake heating operation is performed on the engine.

[0025] Optionally, the vehicle-mounted device 104 may be a vehicle-mounted 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, etc. The above is only an example, and this embodiment does not impose any limitation on this.

[0026] In the related technology, in a low temperature environment, the external friction resistance borne by the engine is particularly large, especially for an engine matched with an automatic transmission. This can easily cause the engine speed to remain unchanged for a long time or rise slowly after reaching a certain higher speed during the starting phase, causing poor combustion in the engine cylinder. In severe cases, it will affect the engine's starting performance and emission performance.

[0027] In order to solve the above technical problems, as an optional implementation method, Figure 2 As shown, the above engine start control method includes:

[0028] S202, obtaining the ambient temperature of the engine, the engine water temperature, and the voltage of the power supply device for starting the engine;

[0029] S204, obtaining the operating state of the engine and the speed change rate of the engine within a preset time period;

[0030] S206, when the ambient temperature, engine water temperature, voltage, operating status and speed change rate all meet preset conditions, determine that the engine is in a pseudo idle condition, and perform an intake air heating operation on the engine.

[0031] In step 202, in actual application, it includes but is not limited to obtaining the current ambient temperature of the vehicle engine and the engine water temperature through the vehicle temperature sensor, and obtaining the voltage of the power supply device that drives the engine to start through the voltage detector. Here, the power supply device during the starting process includes but is not limited to a battery, and the battery capacity will have a large loss, and the battery voltage needs to be monitored from time to time.

[0032] In step 204, in actual application, the current engine operating state is obtained through the Electronic Control Unit (ECU), the engine operating state needs to be always in the starting state, and at the same time, the engine speed is monitored within a certain time range. The speed change rate Δn is lower than a certain set speed change rate, where Δn = current engine speed - engine speed of the previous step.

[0033] In step 206, in actual application, when the ambient temperature, engine water temperature, voltage, operating status and the speed change rate all meet the preset conditions, it is determined that the engine is in a pseudo-idle condition, and an intake air heating operation is performed on the engine, where the intake air heating operation includes activating a strong preheating function.

[0034] In an embodiment of the present invention, a method is adopted for obtaining the ambient temperature of the engine, the engine water temperature, and the voltage of the power supply device for starting the engine; obtaining the operating status of the engine and the speed change rate of the engine within a preset time period; when the ambient temperature, engine water temperature, voltage, operating status and the speed change rate all meet the preset conditions, determining that the engine is in a pseudo-idle condition and performing an intake heating operation on the engine. In the above method, since the "pseudo-idle condition" in the starting stage can be judged based on monitoring conditions such as the intake temperature, engine speed, and battery voltage, it is further determined whether to turn on the intake heating function, thereby achieving the purpose of increasing the intake temperature, improving combustion in the cylinder, rapidly increasing the engine speed, and improving the low-temperature starting performance, thereby solving the technical problem of poor engine starting performance in a low-temperature environment.

[0035] In one or more embodiments, the engine start control method further includes:

[0036] When any one of the ambient temperature, engine water temperature, voltage, operating state and speed change rate does not meet the preset condition, the intake air heating operation of the engine is stopped.

[0037] Specifically, for example, when the engine running state is no longer the cranking state (Cranking), such as switching to the engine Running state, the strong preheating function will exit immediately; when the engine operating condition is no longer in the "pseudo idle condition", the strong preheating function will exit immediately; when the strong preheating time exceeds a certain time, the strong preheating function should exit immediately; when the battery voltage is lower than a certain limit during the engine starting process, the strong preheating function needs to exit immediately; in summary, when at least one of the above conditions is met, the strong preheating cannot be entered and should be exited or turned off immediately. Through the above technical means, the embodiments of the present invention fully consider the application scenarios of strong heating to prevent misoperation and affect the normal engine starting and operation.

[0038] In one or more embodiments, the engine start control method further includes: when any one of the ambient temperature, engine water temperature, voltage, operating status and the speed change rate does not meet the preset condition, the intake heating operation of the engine is not started.

[0039] Specifically, for example, when the ambient temperature of the engine or the engine water temperature does not meet the respective set thresholds, the strong preheating function is prohibited from being turned on.

[0040] In one or more embodiments, the ambient temperature, engine water temperature, voltage, operating state and speed change rate all meet preset conditions, including:

[0041] The ambient temperature of the engine is lower than a first temperature threshold, and the water temperature of the engine is lower than a second temperature threshold; and

[0042] The voltage is higher than a preset voltage threshold, the operating state is a startup state, and the speed change rate is lower than a preset speed change rate.

[0043] The detected ambient temperature is lower than the set temperature threshold, and the engine water temperature is lower than the set water temperature threshold.

[0044] In one or more embodiments, the engine start control method further includes:

[0045] A heating time of the intake air heating operation is determined according to a rotation speed of the engine; wherein the heating time is inversely proportional to the rotation speed.

[0046] Specifically, when the engine speed is much greater than the preset speed, it can be inferred that the engine speed is rising rapidly, and the heating time of the intake air heating operation can be shortened. When the engine speed is not much different from the preset speed, it can be inferred that the engine speed has not changed significantly, and the heating time of the intake air heating operation can be increased accordingly.

[0047] In one or more embodiments, determining the heating time of the intake air heating operation according to the speed of the engine includes:

[0048] The heating time of the intake air heating operation is acquired from a heating schedule according to the current speed of the engine; wherein the heating schedule includes a mapping relationship between the heating time and the speed.

[0049] Specifically, by storing the mapping relationship between the heating time and the speed in the heating schedule, the ECU obtains the corresponding heating time of the intake air heating operation from the heating schedule by determining the current engine speed. Therefore, the intake air heating can be controlled intelligently and conveniently to improve the engine cold start performance.

[0050] In one or more embodiments, the engine start control method further includes: when the intake air heating operation exceeds a preset heating time, or when it is determined that the engine is switched from the pseudo idle condition to the idle state, stopping the intake air heating operation of the engine.

[0051] In an embodiment of the present invention, when the intake air heating operation duration is too long and the engine speed has not changed significantly, the engine may fail at this time, and the intake air heating operation of the engine is automatically stopped to avoid damage to the engine; in addition, the electronic control unit ECU determines that the engine speed change rate is greater than the preset speed change rate, indicating that the engine has switched from the pseudo-idle condition to the idle state, and the intake air heating operation of the engine is automatically stopped at this time.

[0052] In one or more embodiments, the step of heating the engine's intake air comprises:

[0053] Based on an intake air heater arranged in an intake pipe of an engine, the intake air heater is controlled by an electronic control unit to heat the air flowing through the intake air heater.

[0054] During the engine starting process, a large amount of battery energy is usually consumed to ensure a sufficiently high speed during the starter dragging stage. At this time, the intake air heating is usually turned off to reduce the loss of the battery. The embodiment of the present invention controls the opening of the engine intake air heating function by judging the "pseudo idle condition" during the engine starting stage, thereby rapidly increasing the intake air temperature.

[0055] In an application embodiment, if Figure 3 and Figure 4 As shown, the above engine start control method also includes the following steps:

[0056] 1. Strong preheating activation

[0057] 1. This solution determines whether the external conditions meet the activation requirements. First, it detects whether the ambient temperature is lower than the set temperature threshold (EnvT_t<EnvT_Limt), and the engine water temperature is lower than the set water temperature threshold (CEngDsT_t<CEngDsT_Limt);

[0058] 2. During the starting process, the battery capacity will be greatly lost, and the battery voltage needs to be monitored at all times. The battery voltage during the starting process is required to be higher than the battery voltage setting value (BattU_u>BattU_uSet_Limt);

[0059] 3. Next, check whether the running state of the engine has changed. The running state of the engine needs to always be in the starting state (CoEng_st = Cranking);

[0060] 4. The most important thing about this scheme is to accurately detect that the engine operating condition is in a "pseudo idle condition", that is, the engine speed is within a certain time range (StSys_tiFalseIdleChk_C), and the engine speed change rate Δn (speed change rate Δn = current engine speed - engine speed of the previous step) is detected to be lower than a set speed limit (ΔN_SetEng).

[0061] as follows Figure 3 As shown, the above conditions need to be met at the same time for strong preheating (intake air heating function) to be activated. At this time, the intake air heating function is activated for the "pseudo idle condition". The heating time is obtained by checking the time table. The length of the heating time is set according to the range of engine speed changes. For example, the smaller the engine speed deviation, it means that the engine may be in the "pseudo idle condition" for a long time. At this time, the required heating time should be longer to further increase the intake air temperature; if the engine speed deviation is larger, it means that the engine speed has risen rapidly, and the required heating time is shorter.

[0062] 2. Strong preheating exit and shutdown

[0063] 1. When the ambient temperature or engine water temperature does not meet the respective set thresholds, the strong preheating function cannot be activated;

[0064] 2. When the engine is no longer in the cranking state (Cranking), such as switching to the running state, the strong preheating function will be immediately exited;

[0065] 3. When the engine is no longer in the "pseudo idle condition", the strong preheating function will be immediately exited;

[0066] 4. When the strong preheating time exceeds a certain time, the strong preheating function should be exited immediately;

[0067] 5. When the battery voltage is lower than a certain limit during engine starting, the strong preheating function needs to be exited immediately;

[0068] When at least one of the above conditions is met, strong preheating cannot be entered and should be exited or closed immediately. This fully considers the application scenarios of strong heating to prevent misoperation and affect normal engine starting and operation.

[0069] The embodiments of the present invention also have the following beneficial technical effects:

[0070] 1. Judge the activation conditions of strong preheating through complex and strict boundary conditions to prevent accidental entry into strong heating;

[0071] 2. There are strict constraints on the determination of pseudo-idle conditions;

[0072] 3. After entering strong preheating, if the corresponding conditions are not met, you can exit strong preheating immediately. There are clear requirements for the exit and shutdown of strong preheating to avoid the strong preheating function not being able to exit or shut down in time, and play the role of intelligently switching whether the strong preheating works during the starting stage.
