In the related art, the idle speed of the engine is set to a fixed value during idle speed control of the engine, but the idle speed control state is inconvenient to be connected with the non-idle speed control state, because once the idle speed control state is connected with the non-idle speed control state, the idle speed control state has smaller engine speed and larger engine speed, so that the connected engine speed has larger jump, and the driving feeling of a user is poor.

According to the method for controlling the idle speed of the engine, the current idle speed is increased to the target speed along with the change of the running parameters of the vehicle, so that the speed of the engine when the vehicle is about to be converted into the non-idle speed control state and is still in the idle speed control state can be close to the speed when the vehicle is in the non-idle speed control state, the idle speed control state can be better connected with the non-idle speed control state, the jump of the engine speed when the idle speed control state is connected with the non-idle speed control state can be reduced, and the driving feeling of a user is guaranteed, as shown in fig. 1, the method comprises the following steps:

Step 101, when it is determined that a vehicle is in an idle speed control state, a current idle speed of an engine of the vehicle and a current driving mode of the vehicle are obtained.

In this step, the current idle speed of the engine of the vehicle may be obtained by an engine speed sensor, or by reading an engine tachometer of a dashboard of the vehicle.

The current idle speed of the engine of the vehicle is obtained, and the idle speed of the engine of the vehicle can be regulated in real time according to the current idle speeds at different moments.

And 102, acquiring the running parameters of the vehicle corresponding to the current driving mode, and determining the target rotating speed based on the running parameters of the vehicle.

In this step, the operating parameters of the vehicle represent a series of parameters of the vehicle during operation, such as the real-time position of the vehicle, the driving trajectory, the engine start and stop times, the engine temperature, the engine speed, the throttle opening, the idle time duration, the engine on-going hours, the battery voltage, the gearbox gear information, the gearbox gear pattern, the driving speed of the vehicle, the acceleration, the charging demand power or the gear.

Different running parameters of the vehicle are obtained under different current driving modes, and the target rotating speed is determined according to the running parameters of the vehicle, so that the target rotating speed can be changed along with the change of the running parameters of the vehicle, the rotating speed of the engine when the vehicle is about to be converted into a non-idle speed control state and is still in the idle speed control state can be close to the rotating speed in the non-idle speed control state, and the driving experience of a user is ensured.

Step 103, in the idle speed control state, judging whether the current idle speed is smaller than the target speed, and when the current idle speed is smaller than the target speed, increasing the current idle speed of the engine of the vehicle to the target speed so as to enable the engine of the vehicle to run according to the target speed.

In the step, the current idle speed is increased to the target speed which can be changed along with the change of the running parameters of the vehicle, so that the engine speed of the vehicle when the vehicle is about to be converted into the non-idle speed control state and is still in the idle speed control state can be close to the speed in the non-idle speed control state, the idle speed control state can be better connected with the non-idle speed control state, jump of the engine speed when the idle speed control state is connected with the non-idle speed control state is reduced, and the driving feeling of a user is guaranteed.

According to the scheme, when the vehicle is in the idle speed control state, the current idle speed of the engine of the vehicle and the current driving mode of the vehicle are obtained, the operation parameters of the vehicle corresponding to the current driving mode are obtained, the target speed is determined based on the operation parameters of the vehicle, the target speed can be changed along with the change of the operation parameters of the vehicle, in the idle speed control state, whether the current idle speed is smaller than the target speed is judged, when the current idle speed is smaller than the target speed, the current idle speed of the engine of the vehicle is increased to the target speed so that the engine of the vehicle can operate according to the target speed, and the mode that the current idle speed is increased to the target speed along with the change of the operation parameters of the vehicle enables the engine speed of the vehicle to be close to the speed in the non-idle speed control state when the vehicle is about to be converted into the non-idle speed control state, so that the idle speed control state can be better connected with the non-idle speed control state, the engine speed can be jumped when the idle speed control state is reduced, and driving feeling of a user is ensured.

In some embodiments, step 102 comprises:

and 1021, judging whether the current driving mode is an electric driving mode, and obtaining a judging result.

Step 1022, when the determination result is no, acquiring the vehicle charging demand power and the current running speed, and determining the target rotation speed based on the vehicle charging demand power and the current running speed of the vehicle.

Step 1023, when the judgment result is yes, acquiring the vehicle charging demand power and the current running speed, and determining the target rotating speed based on the vehicle charging demand power and the current running speed of the vehicle.

In this step, in order to secure the power timeliness of the engine, if the vehicle is driven in the idle control state, the power source of the vehicle is electric, so it is possible to determine whether the vehicle is driven in the idle control state by judging whether the current drive mode is the electric drive mode.

The electric drive mode may be an electric four-drive mode, an electric rear-drive mode, or an electric front-drive mode.

When the judgment result is negative, the vehicle is not driven although in the idle speed control state, for example, the engine is in a constant starting state, and the running speed of the vehicle is zero, the acquired running parameters of the vehicle are the charging required power and the current running speed of the vehicle, and the target rotating speed is determined based on the charging required power and the current running speed.

Further, when the vehicle is in the idle control state and the vehicle is not driven, it is possible to shift to the non-idle control state by engaging a gear and stepping on a throttle.

At this time, when the vehicle is shifted to the non-idle control state, the electric drive mode is engine drive.

And when the judgment result is yes, the fact that the vehicle is driven at the moment is indicated, the current gear of the vehicle is obtained, the obtained running parameters of the vehicle are the current gear of the vehicle and the current running speed of the vehicle, and the target rotating speed is determined based on the current gear and the current running speed.

Further, when the vehicle is in the idle control state and the vehicle has been driven, the current drive mode is the electric drive mode, it is possible to switch to the non-idle control state by engaging and stepping on the accelerator, and the running speed reaches a preset speed threshold, which may be set in a range of 30 to 50 km/h, for example, 30 km/h, 35 km/h, or 40 km/h, where 30 km/h is preferable, depending on the circumstances.

At this time, when the vehicle is shifted to the non-idle control state, the current drive mode is shifted from the electric drive mode to the engine drive mode.

In some embodiments, in step 1022, the determining the target rotational speed based on the vehicle charging demand power and the current running speed of the vehicle includes:

Step 10221, when the vehicle charging demand power is less than a preset demand power threshold, taking the preset first rotation speed as an intermediate target rotation speed of an engine of the vehicle.

Step 10222, when the vehicle charging demand power is greater than or equal to a preset demand power threshold, taking the preset second rotation speed as an intermediate target rotation speed of the engine of the vehicle.

Step 10223, determining the target rotational speed based on the intermediate target rotational speed and the current running speed.

In the above scheme, the vehicle charging demand power can represent the remaining power level of the vehicle, and when the vehicle charging demand power is higher, it is indicated that the remaining power level of the vehicle is lower, and it is necessary to charge as soon as possible. When the vehicle charging demand power is low, the remaining capacity of the vehicle is high, and quick charging is not needed.

The speed of the engine can influence the charging speed, and the larger the speed of the engine is, the faster the charging is, the smaller the speed of the engine is, and the slower the charging is.

Therefore, the middle target rotating speed of the engine of the vehicle can be determined according to the charging demand power of the vehicle and the preset demand power threshold value, in addition, the running speed can influence the noise, vibration and harshness (Noise, vibration, harshness, NVH) performance of the vehicle, and the noise, vibration and harshness are used for measuring the using comfort of the vehicle, so that the target rotating speed is determined through the middle target rotating speed and the current running speed, the charging speed of the vehicle can be guaranteed, and the using comfort of the vehicle can be guaranteed.

Further, the vehicle charge demand power may be determined by a product process of a difference between the remaining amount of the battery and a preset target amount of the battery, and a voltage of the charging device.

When the vehicle charging demand power is smaller than the preset demand power threshold, the vehicle is higher in residual electric quantity, rapid charging is not needed, and the lower the rotating speed of the engine is, the slower the charging is, the lower preset first rotating speed is used as the middle target rotating speed of the vehicle engine.

When the charging demand power of the vehicle is greater than or equal to the preset demand power threshold, the vehicle is indicated to have lower residual electric quantity, quick charging is needed, and the higher the rotating speed of the engine is, the faster the charging is, and the higher preset second rotating speed is taken as the middle target rotating speed of the vehicle engine at the moment.

The first preset rotational speed may be set according to circumstances, and may range from 800 to 1200r, for example, 1000r, 1050r, or 1200r, where the first preset rotational speed is preferably 1050r.

The second preset rotational speed may be set in a range of 1300 to 1600r, for example 1450r, 1500r or 1550r, depending on the case, where the second preset rotational speed is preferably 1500r.

The preset required power threshold may be set according to circumstances in a range of 5kw to 8kw, for example, 5kw, 6kw or 7kw, where the preset required power threshold is preferably 7kw.

Through predetermining first rotational speed or predetermining the second rotational speed as middle target rotational speed, can match the rotational speed of vehicle and can satisfy the demand that charges of vehicle self, ensure that the vehicle can charge in time, avoid taking place the problem of insufficient power.

In some embodiments, step 10223 comprises:

step 102231, searching an idle speed maximum value corresponding to the current running speed from a preset first database, wherein the preset first database is a database storing idle speed maximum values corresponding to different running speeds.

And 102232, selecting the minimum rotation speed of the maximum idle rotation speed and the intermediate target rotation speed as the target rotation speed.

In the scheme, the running speed can influence the noise, vibration and sound vibration roughness performance of the vehicle, and the noise, vibration and sound vibration roughness is used for measuring the comfort level of the vehicle.

Therefore, the current running speed of the vehicle can be used as a basis, and the maximum value of the idle speed corresponding to the current running speed can be searched from the preset first database.

The determining process of the first database is as follows:

and determining the maximum idle speed corresponding to each running speed when the performance of noise, vibration and acoustic vibration roughness can be guaranteed, and then storing each running speed and the corresponding maximum idle speed in a data table.

The first database may also be stored in the form of a respective driving speed range, for example:

greater than or equal to 0 km/h, less than 10 km/h;

greater than or equal to 10 km/h, less than 15 km/h;

greater than or equal to 15 km/h and less than 30 km/h.

Searching an idle speed maximum value corresponding to the current running speed from a preset first database. Or searching an idle speed maximum value corresponding to the speed range where the current running speed is located from a preset first database.

The minimum rotation speed of the maximum idle rotation speed and the middle target rotation speed is selected as the target rotation speed, so that the selection of the rotation speed is limited, the use comfort of the vehicle can be ensured, the problem that the vehicle jolts or the noise in the vehicle is caused by overlarge rotation speed is avoided, and the use feeling of a user is influenced.

In some embodiments, in step 1023, the determining a target rotational speed based on the current gear of the vehicle and the current travel speed of the vehicle includes:

In the above scheme, when the vehicle is still in the idle speed control state, the rotation speed corresponding to the current gear and the current running speed is searched in real time from the preset second database as the target rotation speed, so that the target rotation speed can adaptively change along with different running speeds and gears, the rotation speed of the engine when the vehicle is about to be converted into the non-idle speed control state and still in the idle speed control state can be close to the rotation speed in the non-idle speed control state, the idle speed of the engine of the vehicle is regulated according to the target rotation speed, the idle speed control state can be better connected with the non-idle speed control state, the jump of the rotation speed of the engine when the idle speed control state is connected with the non-idle speed control state can be reduced, and the driving feeling of a user is ensured.

In some embodiments, the idle flag of the engine of the vehicle is marked with a status code, the status code comprising a first status code and a second status code.

In step 101, the determining that the vehicle is in the idle speed control state includes:

step 1011, when a selected instruction of a preset driving mode is received in a starting state of the vehicle, determining whether the vehicle is in an idle speed control state according to the state code.

Step 1012, when the status code is the first status code, determining that the vehicle is not in an idle speed control state.

In step 1013, when the status code is the second status code, it is determined that the vehicle is in the idle speed control state.

In the above-described aspect, the preset driving mode may be a snow/mud/sand mode, a standard mode, an economy mode, a sport mode, an anti-slip mode, or a rough road mode, where the preset driving mode is preferably a snow/mud/sand mode.

The selected instruction may be a voice instruction or a touch instruction, or may be a button corresponding to clicking a preset driving mode.

When a selected instruction of a preset driving mode is received, whether the idle speed zone bit is activated or not is determined according to a state code on the idle speed zone bit of the engine, when the state code is a first state code, the idle speed zone bit is not activated, the idle speed control state of the vehicle is indicated, and the process of determining and adjusting the idle speed of the engine of the vehicle is not executed at the moment.

When the status code is the second status code, the idle speed flag bit is activated, and the idle speed control status of the vehicle is indicated.

Wherein the first status code and the second status code can be set according to specific situations, and the first status code is preferably 0, and the second status code is preferably 1.

According to the state code of the idle speed zone bit of the engine, whether the vehicle is in an idle speed control state or not can be intuitively and rapidly determined.

Based on the same inventive concept, an application scenario corresponding to the engine idle speed control method of the above embodiment is specifically described, as shown in fig. 2, specifically as follows:

when the vehicle mode selects a snow/mud/sand mode (i.e. a preset driving mode), judging whether an idle speed zone bit of the engine is activated or not, and if the idle speed zone bit is not activated, not setting an idle speed target rotating speed.

If the idle speed flag bit is activated, calculating the vehicle charging demand power, and judging whether the vehicle charging power is smaller than 7kw (namely a preset demand power threshold value).

When the required power is less than 7kw, the target rotation speed is set to 1050r (i.e., the preset first rotation speed), and at this time, the target rotation speed a (i.e., the intermediate target rotation speed) is set to 1050r.

When the required power is greater than or equal to 7kw, the target rotational speed is set to 1500r (i.e., the preset second rotational speed), and at this time, the target rotational speed a is set to 1500r.

The method comprises the steps of reading the running speed (namely the current running speed) of a vehicle, obtaining an idle speed maximum value through the table look-up (namely the first database) of the speed (namely the current running speed), comparing a target speed A with the idle speed maximum value, and selecting the minimum speed setting target speed B (namely the target speed) in the target speed A and the idle speed maximum value.

And then judging whether the current mode (i.e. the current driving mode) of the vehicle is an electric four-wheel drive (i.e. the electric driving mode), reading the current gear of the vehicle when the current mode of the vehicle is the electric four-wheel drive, obtaining a target rotating speed C (i.e. the target rotating speed) through the table look-up (i.e. the second database) of the vehicle speed (i.e. the current running speed) and the gear (i.e. the current gear), and adjusting the idle rotating speed of the engine to the target rotating speed C by the self-adapting idle rotating speed of the engine.

When the vehicle mode is not the electric four-wheel drive mode, the target rotation speed B is output, the engine is self-adaptive to the idle rotation speed, and the idle rotation speed of the engine is regulated to the target rotation speed B.

It should be noted that, the method of the embodiment of the present application may be performed by a single device, for example, a computer or a server. The method of the embodiment can also be applied to a distributed scene, and is completed by mutually matching a plurality of devices. In the case of such a distributed scenario, one of the devices may perform only one or more steps of the method of an embodiment of the present application, the devices interacting with each other to accomplish the method.
