Description
Technical Field
The present disclosure relates to the field of vehicles, and in particular, to a vehicle control method, device, readable storage medium, and vehicle.
Background
With the rapid development of the automobile industry in China, domestic automobiles gradually move towards globalization, so that the use context of the automobiles in cold environments appears, and the requirements of people on the riding comfort and the driving safety of the automobiles are higher and higher. In cold environments, a vehicle is placed outside and needs to be quickly defrosted, and the air conditioner defrosting at the present stage cannot quickly defrost in a short time. After the vehicle is driven and stopped in a cold environment, the frosting and icing of the vehicle glass are mainly caused by the fact that hot air still remains in the vehicle after people leave the vehicle, at the moment, the vehicle glass is hot, outside cold air or snow falls on the glass, the cold air is condensed into water when meeting the hot glass, the snow falls on the hot glass and melts, in the process, the temperature in the vehicle starts to be reduced, and when the temperature in the vehicle is reduced to be close to the temperature outside the vehicle, the water on the glass starts to be frosted and iced. If the frost and ice on the glass need to be removed, a great deal of time is consumed.
Most users open the door after getting off the vehicle to blow outside cold air into the vehicle to reduce the temperature in the vehicle and reduce the temperature of the vehicle glass, so as to reduce the ice formation amount of the vehicle glass; or the cotton cloth is covered on the outer side of the glass of the vehicle to prevent frost and ice caused by cold air close to the glass. Most vehicles in the alpine region have the electric heating function of the front windshield, so that the whole front windshield can be quickly heated, and frost on the front windshield can be quickly removed. However, the power of the electrically heated glass of the front windshield is generally high, the required electric quantity is large, in order to maintain the electrical balance, a high-power generator needs to be selected, the displacement of the middle-end and low-end vehicle is low, the generated energy of the generator is low, if the front windshield is added, other electric heating functions such as seat heating, steering wheel heating and rearview mirror heating must be removed, and the driving comfort is greatly reduced. The vehicle is heated by a rear windshield, and the defrosting can be rapidly realized through the electric heating function for frosting and icing the rear windshield. But has no corresponding heating function for the frosting and icing of the four-door glass. The main and auxiliary driving glasses can remove frost and ice in the visual field area through the defrosting function of the air conditioner, frost and ice at other parts can be removed only by scraping, or after the temperature of the air conditioner in the vehicle is increased, the frost and ice are removed by melting after the temperature of the glass is increased.

Detailed Description
The following detailed description of the embodiments of the disclosure refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart of a vehicle control method according to an exemplary embodiment of the present disclosure. The method may be applied to a vehicle, illustratively, to a controller on the vehicle, such as a body controller. As shown in fig. 1, the method may include S101 to S105.
And S101, controlling the engine to run at an idle speed after receiving the vehicle locking instruction.
Illustratively, after getting off the vehicle, the user may issue a car locking command through a mobile phone APP (Application), and the car locking command is transmitted to a T-Box (Telematics Box, vehicle-mounted wireless terminal) through a TSP (Telematics Service Provider) platform. And after the T-Box authenticates the user identity as a legal user, the T-Box wakes up the whole vehicle network and sends a vehicle locking instruction to the controller. After the controller receives a vehicle locking instruction, the controller controls the anti-theft components such as the electronic steering column lock, the gearbox and the like to be in a locking and fortifying state, and in addition, the controller controls the engine to run at an idle speed instead of immediately flameout.
Alternatively, the user may issue the locking command through the key controller after getting off the vehicle.
S102, obtaining the temperature inside and outside the vehicle.
For example, the controller may acquire the in-vehicle temperature and the out-vehicle temperature by temperature sensors provided inside and outside the vehicle, respectively.
Alternatively, the off-board temperature may be obtained by a T-Box, which may communicate with the TSP platform, from which weather information for the area in which the vehicle is located may be obtained to obtain the off-board temperature.
And S103, determining whether to start the air conditioner or not according to the temperature inside the vehicle and the temperature outside the vehicle.
And S104, under the condition that the air conditioner is determined to be started, determining the working mode of the air conditioner according to the temperature inside and outside the vehicle, and controlling the air conditioner to operate according to the working mode during the idling operation of the engine.
And S105, controlling the engine to be shut down when the engine shut-down condition is met, wherein the air conditioner is in a closed state when the engine is shut down.
Through the technical scheme, after the vehicle is locked, the engine does not immediately shut down, but runs at an idle speed first. In addition, whether the air conditioner needs to be started or not is determined based on the temperature inside and outside the vehicle, and the working mode of the air conditioner is further determined by combining the temperature inside and outside the vehicle under the condition that the air conditioner needs to be started. And finally, controlling the air conditioner to operate according to the determined working mode during the idle running period of the engine. So, can effectively prevent and reduce the problem that car glass frosted, freezes behind cold weather driving, need not the front windshield electric heating function that electric power consumption is high, can effectively save the electric quantity, avoid simultaneously in order to maintain the electric balance and lead to the reduction of vehicle travelling comfort, promote the experience of user's vehicle use and feel. In addition, the problem of hot shutdown of the turbocharger of the supercharged engine caused by flameout of the engine immediately after the vehicle is locked in the related art is effectively solved, carbon deposition in the turbocharger is reduced, and the service life of the turbocharger is prolonged.
In an alternative embodiment of the present disclosure, the user may manually set the engine idle operation period. That is, in this embodiment, the method may further include the steps of: and receiving the idle running time length of the engine set by a user. According to the method, the idle running time of the engine can be automatically judged by a user according to the outside temperature and the inside temperature, then the idle running time of the engine can be set through the mobile phone APP, the idle running time of the engine set by the user can be transmitted to the T-Box through the TSP platform, and then transmitted to the controller through the T-Box, so that the controller can obtain the idle running time of the engine. For example, the engine idle operation time period may be 5min to 10 min.
Thus, after the vehicle locking instruction is received, the engine is controlled to run at the idle speed according to the idle speed running time length of the engine. In this case, the engine stall condition may be: the engine is idling for the engine idle operation period. That is, after the engine is idle-operated for the engine idle-operation period, the engine is controlled to be turned off, and the air conditioner is controlled to be in an off state.
In addition, in an embodiment in which the user manually sets the idle operation time period of the engine, the controller may determine whether to turn on the air conditioner in conjunction with the inside and outside temperatures of the vehicle as follows:
(1) if the temperature in the vehicle is greater than or equal to the first temperature threshold in the vehicle, and the temperature outside the vehicle is greater than the first temperature threshold outside the vehicle and less than or equal to the second temperature threshold outside the vehicle, determining to start the air conditioner;
(2) if the temperature in the vehicle is greater than or equal to the first temperature threshold in the vehicle and the temperature outside the vehicle is less than or equal to the first temperature threshold outside the vehicle, determining to start the air conditioner;
(3) if the temperature in the vehicle is greater than the second temperature threshold in the vehicle and less than the first temperature threshold in the vehicle, and the temperature outside the vehicle is less than or equal to the second temperature threshold outside the vehicle, determining to start the air conditioner;
(4) if the temperature in the vehicle is less than or equal to the second temperature threshold in the vehicle and the temperature outside the vehicle is less than or equal to the second temperature threshold outside the vehicle, determining not to start the air conditioner;
(5) and if the outside temperature is greater than the second outside temperature threshold value, determining not to start the air conditioner.
For example, the first in-vehicle temperature threshold may be 16 ℃, the second in-vehicle temperature threshold may be 0 ℃, the first out-vehicle temperature threshold may be-20 ℃, and the second out-vehicle temperature threshold may be 0 ℃. It should be noted that the specific temperature values mentioned herein are only for exemplary purposes and are not used to limit the specific values of the temperature thresholds, and the temperature thresholds can be set according to actual needs.
That is, if the temperature in the vehicle is more than or equal to 16 ℃ and minus 20 ℃ is less than or equal to 0 ℃ outside the vehicle, or if the temperature in the vehicle is more than or equal to 16 ℃ and the temperature outside the vehicle is less than or equal to minus 20 ℃, or if the temperature in the vehicle is more than or equal to 0 ℃ and the temperature outside the vehicle is less than or equal to 16 ℃ and the temperature outside the vehicle is less than or equal to 0 ℃, the temperature in the vehicle is higher and the temperature outside the vehicle is lower. When cold air meets the hot glass, water is condensed into the cold air, snowflakes fall on the hot glass to melt, and when the temperature in the automobile is reduced to be close to the temperature outside the automobile, the water on the glass begins to frost and ice. Therefore, in these cases, it is determined that the air conditioner needs to be turned on to rapidly lower the temperature in the vehicle.
If the temperature in the vehicle is less than or equal to 0 ℃ and the temperature outside the vehicle is less than or equal to 0 ℃, the temperature in the vehicle and the temperature outside the vehicle are both lower, and at the moment, cold or snowflakes are not easy to form water on the glass, so that the glass is not easy to frost and ice. Therefore, in this case, it is determined that the air conditioner does not need to be turned on.
If the temperature outside the vehicle is higher than 0 ℃, the temperature outside the vehicle is proved to be higher, and the frosting and the icing of the glass are not easy to cause, so that the air conditioner does not need to be started under the condition.
Under the condition that the air conditioner needs to be started, the controller can determine the working mode of the air conditioner according to the temperature inside the vehicle and the temperature outside the vehicle. Specifically, the method comprises the following steps:
(1) if the temperature in the air conditioner is greater than or equal to a first temperature threshold in the air conditioner, and the temperature outside the air conditioner is greater than a first temperature threshold outside the air conditioner and less than or equal to a second temperature threshold outside the air conditioner, determining that the working mode of the air conditioner is a first working mode;
(2) if the temperature in the air conditioner is greater than or equal to the first temperature threshold in the air conditioner and the temperature outside the air conditioner is less than or equal to the first temperature threshold outside the air conditioner, determining that the working mode of the air conditioner is a second working mode;
(3) if the in-vehicle temperature is greater than the second in-vehicle temperature threshold and less than the first in-vehicle temperature threshold, and the out-vehicle temperature is less than or equal to the second out-vehicle temperature threshold, determining that the working mode of the air conditioner is a third working mode;
and the air speed of the blower in the first working mode is lower than that in the second working mode and higher than that in the third working mode.
As described above, in the case where the in-vehicle temperature is greater than or equal to the first in-vehicle temperature threshold value, the outside temperature is greater than the first outside temperature threshold value and less than or equal to the second outside temperature threshold value, the latter causes a greater difference in the in-vehicle outside-vehicle temperature than in the case where the outside temperature is less than or equal to the first outside temperature threshold value, and therefore, a greater blowing effect is required to lower the in-vehicle temperature more quickly, that is, the blower wind speed in the first operation mode is smaller than the blower wind speed in the second operation mode.
When the outside temperature is less than or equal to the second outside temperature threshold, and the inside temperature is greater than the second inside temperature threshold and less than the first inside temperature threshold, the latter causes a greater difference in the inside and outside temperature than the inside temperature is greater than or equal to the first inside temperature threshold, and therefore, a greater blowing effect is required to lower the inside temperature faster, that is, the blower speed in the third operating mode is less than the blower speed in the first operating mode and less than the blower speed in the second operating mode.
In addition to the difference in the blower wind speed, other states may be the same in each operation mode of the air conditioner, for example, the external cycle may be turned on, the cooling mode may be turned on, the blower may be turned on, the compressor may be turned on, and the air conditioner may be operated at the minimum air conditioner temperature, blowing the front windshield and the main and sub glasses.
The above describes the embodiment in which the user manually sets the engine idle operation time period. In another alternative embodiment provided by the present disclosure, the user need not manually set the engine idle operation period, but rather the controller may automatically control the period of engine idle operation. In this case, the engine stall condition may include: and the air conditioner runs for a time length which is more than or equal to a preset time length according to the determined working mode, and the temperature in the vehicle is less than or equal to a third temperature threshold value in the vehicle. For example, the third in-vehicle temperature threshold is a preset value, and when the in-vehicle temperature is reduced to be less than or equal to the third in-vehicle temperature threshold, the in-vehicle temperature is low, and the temperature difference between the in-vehicle temperature and the out-vehicle temperature is small, so that frosting and icing of the vehicle glass are not easily caused. For example, the third in-vehicle temperature threshold is 1 ℃, but is not limited to this value, and the third in-vehicle temperature threshold may be specifically set according to actual needs.
The preset time period described above may be set in the controller in advance. The preset time period defines the minimum time period for the air conditioner to operate. For example, the preset time period may be set to 5 min. As such, several situations may arise:
firstly, the air conditioner firstly reaches the preset time length according to the determined operation mode, the temperature in the vehicle is still larger than the temperature threshold value in the third vehicle at the time, then, the air conditioner can continuously operate according to the determined operation mode until the temperature in the vehicle is reduced to be smaller than or equal to the temperature threshold value in the third vehicle, at the time, the flameout condition of the engine is met, the controller controls the engine to flameout, and the air conditioner is controlled to be in the off state.
Secondly, the air conditioner runs according to the determined working mode for a period of time which does not reach the preset period of time, the temperature in the vehicle is reduced to be less than or equal to a third vehicle temperature threshold value, under the condition, the air conditioner can continue to run according to the determined working mode for a period of time until the preset period of time is reached, at the moment, the engine flameout condition is met, the controller controls the engine to flameout, and the air conditioner is controlled to be in a closed state.
In an embodiment where the controller automatically controls the length of time that the engine runs at idle, the controller may determine whether to turn on the air conditioner in conjunction with the vehicle interior and exterior temperatures as follows:
(1) if the temperature inside the vehicle is greater than or equal to the first temperature threshold inside the vehicle and the temperature outside the vehicle is less than or equal to the second temperature threshold outside the vehicle, the air conditioner is determined to be started;
(2) if the temperature inside the vehicle is greater than the second temperature threshold inside the vehicle and less than the first temperature threshold inside the vehicle, and the temperature outside the vehicle is less than or equal to the second temperature threshold outside the vehicle, the air conditioner is determined to be started;
(3) if the temperature in the vehicle is less than or equal to the second temperature threshold in the vehicle and the temperature outside the vehicle is less than or equal to the second temperature threshold outside the vehicle, determining not to start the air conditioner;
(4) and if the outside temperature is greater than the second outside temperature threshold value, determining not to start the air conditioner.
For example, the first in-vehicle temperature threshold may be 16 ℃, the second in-vehicle temperature threshold may be 0 ℃, and the second out-vehicle temperature threshold may be 0 ℃. It should be noted that the specific temperature values mentioned herein are only for exemplary purposes and are not used to limit the specific values of the temperature thresholds, and the temperature thresholds can be set according to actual needs.
That is, if the temperature in the vehicle is more than or equal to 16 ℃ and the temperature outside the vehicle is less than or equal to 0 ℃, or if the temperature in the vehicle is more than 0 ℃ and less than 16 ℃ and the temperature outside the vehicle is less than or equal to 0 ℃, the temperature in the vehicle is higher and the temperature outside the vehicle is lower. When cold air meets the hot glass, water is condensed into the cold air, snowflakes fall on the hot glass to melt, and when the temperature in the automobile is reduced to be close to the temperature outside the automobile, the water on the glass begins to frost and ice. Therefore, in these cases, it is determined that the air conditioner needs to be turned on to rapidly lower the temperature in the vehicle.
If the temperature in the vehicle is less than or equal to 0 ℃ and the temperature outside the vehicle is less than or equal to 0 ℃, the temperature in the vehicle and the temperature outside the vehicle are both lower, and at the moment, cold or snowflakes are not easy to form water on the glass, so that the glass is not easy to frost and ice. Therefore, in this case, it is determined that the air conditioner does not need to be turned on.
If the temperature outside the vehicle is higher than 0 ℃, the temperature outside the vehicle is proved to be higher, and the frosting and the icing of the glass are not easy to cause, so that the air conditioner does not need to be started under the condition.
Under the condition that the air conditioner needs to be started, the controller can determine the working mode of the air conditioner according to the temperature inside the vehicle and the temperature outside the vehicle. Specifically, the method comprises the following steps:
(1) if the temperature inside the vehicle is greater than or equal to the first temperature threshold inside the vehicle and the temperature outside the vehicle is less than or equal to the second temperature threshold outside the vehicle, determining that the working mode of the air conditioner is a second working mode;
(2) if the in-vehicle temperature is greater than the second in-vehicle temperature threshold and less than the first in-vehicle temperature threshold, and the out-vehicle temperature is less than or equal to the second out-vehicle temperature threshold, determining that the working mode of the air conditioner is the first working mode;
and the air speed of the blower in the first working mode is less than that in the second working mode.
As described above, in the case where the outside temperature is less than or equal to the second outside temperature threshold value, the inside temperature is greater than the second inside temperature threshold value and less than the first inside temperature threshold value, as compared to the case where the inside temperature is greater than or equal to the first inside temperature threshold value, the latter causes a greater difference in the inside and outside temperature of the vehicle, and therefore, a greater blowing effect is required to lower the inside temperature more quickly, that is, the blower wind speed in the first operation mode is less than the blower wind speed in the second operation mode.
In addition to the difference in the blower wind speed, other states may be the same in each operation mode of the air conditioner, for example, the external cycle may be turned on, the cooling mode may be turned on, the blower may be turned on, the compressor may be turned on, and the air conditioner may be operated at the minimum air conditioner temperature, blowing the front windshield and the main and sub glasses.
Based on the same inventive concept, the disclosure also provides a vehicle control device.

the first control module 201 is further configured to control the engine to shut down when an engine shut down condition is met, wherein the air conditioner is in an off state when the engine is shut down.

In addition, whether the air conditioner needs to be started or not is determined based on the temperature inside and outside the vehicle, and the working mode of the air conditioner is further determined by combining the temperature inside and outside the vehicle under the condition that the air conditioner needs to be started. And finally, controlling the air conditioner to operate according to the determined working mode during the idle running period of the engine.
