Description

Technical Field

[0001] The present application relates to the field of new energy vehicle technology, and specifically to a vehicle intelligent auxiliary heating control method, control device, terminal equipment and storage medium. Background Art

[0002] At present, the use of PTC (Positive Temperature Coefficient) car heaters to provide heating for air conditioning in new energy vehicles is the main solution for the vehicle thermal management system. However, due to its own technical limitations, the maximum heating power of PTC heaters is limited, and it cannot fully meet the heating needs of the passenger compartment of pure electric vehicles in low temperature environments. Therefore, in new energy vehicles, especially extended-range vehicles, range extenders are usually used to provide auxiliary heating to meet the heating needs of the passenger compartment in pure electric mode. At present, the more common range extender auxiliary heating control strategy is to determine whether to start the range extender auxiliary heating by judging whether the ambient temperature is below a certain limit. However, the accuracy of judging based on ambient temperature alone is low and cannot accurately respond to the heating needs of the passenger compartment. Therefore, it is very necessary to explore a strategy to more accurately control the activation of the range extender auxiliary heating function to obtain a better response effect.

[0053] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0054] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0055] Example 1

[0056] As mentioned in the background technology, in order to solve the problems in the prior art, this application proposes a vehicle intelligent auxiliary heating control method, such as Figure 1 As shown, the following steps are included:

[0057] S100: Acquire a first real-time water temperature in a water path of an air-conditioning system; optionally, the first real-time water temperature is measured by a temperature sensor provided in the water path of the air-conditioning system;

[0058] S101: Querying a first database to obtain a first target water temperature corresponding to the current air conditioning set temperature; the first database includes multiple sets of air conditioning set temperatures and the first target water temperature corresponding to each set of air conditioning set temperatures. Specifically, after an occupant enters the cockpit, they turn on the air conditioning according to their needs and set a target temperature on the air conditioning adjustment panel. By querying the first database, the first target water temperature corresponding to the set target temperature is obtained. For example, in an actual application scenario, when the occupant sets the target temperature to 25°C according to their needs, as shown in Table 1, the corresponding first target water temperature can be obtained as 70°C.

[0059] Table 1

[0060]

[0061] S102: Calculating the difference between the first real-time water temperature and the first target water temperature to obtain a first water temperature difference; specifically, when the first real-time water temperature is 57° C., the first water temperature difference obtained by subtracting the first real-time water temperature from the first target water temperature is -13° C.;

[0062] S103: When it is determined that the first water temperature difference is less than a first preset threshold, the range extender auxiliary heating is started; wherein, the first preset threshold is the minimum water temperature difference to ensure a good heating effect in the passenger compartment. In the actual application scenario of this embodiment, the first preset threshold is -7°C; when the first water temperature difference is less than the first preset threshold, the range extender auxiliary heating is started; the first real-time water temperature collected by the temperature sensor in the water circuit of the air-conditioning system is a contact temperature, which has high sensitivity and accuracy. This solution determines whether to start the range extender auxiliary heating based on the size of the first water temperature difference. Compared with deciding whether to start the range extender auxiliary heating by judging whether the ambient temperature is much lower than the target temperature, this solution can respond to the heating needs of the passenger compartment more intelligently and accurately.

[0063] Furthermore, before obtaining the first real-time water temperature in the water path of the air-conditioning system, the method further includes the following steps:

[0064] Get the first real-time temperature of the outdoor environment;

[0065] When it is determined that the first real-time temperature is less than a second preset threshold, executing the step of obtaining the first real-time water temperature in the water path of the air-conditioning system;

[0066] The first real-time temperature is the vehicle's outdoor ambient temperature, measured by a temperature sensor located in the vehicle's front cabin. The second preset threshold is the outdoor ambient temperature value that ensures a good driving experience for the passenger compartment. When the vehicle is driven in a low-temperature environment, the vehicle's outdoor ambient temperature is also collected before determining the water temperature difference. The second preset threshold is set to -12°C. If the collected first real-time temperature is -15°C, which is lower than the second preset threshold, then a water temperature difference determination is performed.

[0067] Furthermore, before obtaining the first real-time temperature of the outdoor environment, the method further includes the following steps:

[0068] In response to a current real-time low vehicle temperature signal, starting the first heating component;

[0069] collecting the operating power of the first heating component in real time;

[0070] When it is determined that the operating power is equal to a fifth preset threshold, collecting a fifth real-time temperature in the current vehicle; the fifth preset threshold is the maximum operating power of the first heating component;

[0071] When it is determined that the fifth real-time temperature is less than the current air-conditioning set temperature, executing the step of obtaining the first real-time temperature of the outdoor environment;

[0072] The first heating component is a PTC heater. Specifically, the real-time temperature inside the vehicle is measured by a temperature sensor located in the passenger compartment. When the real-time temperature inside the vehicle is lower than 14°C, the vehicle server sends a signal indicating that the current real-time temperature inside the vehicle is too low. The air conditioning system responds to this signal and activates the PTC heater for heating. When the maximum operating power of the PTC heater in the vehicle is 6 kW and the real-time collected PTC operating power reaches the maximum operating power, the ambient temperature at that time is collected, which is the fifth real-time temperature. If the measured fifth real-time temperature is 22°C, it is determined to be lower than the current air conditioning set temperature of 25°C. At this time, the outdoor ambient temperature and the water temperature difference are then determined.

[0073] In addition, if the fifth real-time temperature is measured to have reached the current air-conditioning set temperature, or the first real-time temperature collected is greater than or equal to the second preset threshold, it is determined that the range extender auxiliary heating is not started; by determining whether to start the range extender auxiliary heating through multiple judgments, intelligent control of the range extender auxiliary heating can be achieved, and the heat required for heating the passenger compartment can be provided more accurately.

[0074] Example 2

[0075] On the basis of Example 1, further, before obtaining the first real-time temperature of the outdoor environment, the following steps are further included:

[0076] In response to an input signal indicating that the air conditioning set temperature has increased, the difference between the target water temperatures corresponding to the air conditioning set temperatures before and after the change is calculated to obtain a second water temperature difference;

[0077] When it is determined that the absolute value of the second water temperature difference is greater than or equal to a third preset threshold, obtaining a second real-time temperature of the outdoor environment;

[0078] When it is determined that the second real-time temperature is less than the second preset threshold, obtaining the second real-time water temperature in the water path of the air-conditioning system;

[0079] querying the first database to obtain a second target water temperature corresponding to the current air conditioner set temperature;

[0080] calculating a difference between the second real-time water temperature and the second target water temperature to obtain a third water temperature difference;

[0081] When it is determined that the third water temperature difference is less than the first preset threshold, controlling the first timer to start timing;

[0082] When it is determined that the timing time of the first timer is equal to the first preset time length, starting the range extender to assist in heating;

[0083] When the vehicle is driving, the passengers may need to leave the passenger cabin for a period of time due to some reasons. During the period when the passengers leave, the vehicle doors are closed. At this time, the set temperature of the air conditioner in the vehicle remains unchanged at 25°C. When the outdoor ambient temperature is too low, the passengers will feel that the target temperature in the passenger cabin cannot meet their heating needs after returning to the passenger cabin. At this time, the passengers can increase the temperature to 28°C on the air conditioning adjustment panel. According to Table 1, the second water temperature difference is 19°C. The third preset threshold is the maximum target water temperature difference to ensure comfortable driving in the passenger cabin. Its value can be set to 6°C based on subjective driving evaluation and other conditions. At this time, the absolute value of the second water temperature difference is greater than the third preset threshold, and it is necessary to perform the temperature control in Example 1 again. The first preset time is set to 30s. After the condition for starting the range extender auxiliary heating is met, the first timer is controlled to start timing. When the first timer reaches 30s, the range extender auxiliary heating is started again. In this embodiment, a delayed start judgment strategy is set for starting the range extender auxiliary heating, which can avoid giving passengers a negative impression that the range extender operates together with the air-conditioning panel adjustment. At the same time, when the air-conditioning set temperature suddenly increases due to an occupant's accidental touch, the delay strategy can also provide the occupant with a certain amount of adjustment time. In addition, when the target temperature water temperature difference change is less than the third preset threshold, the range extender can immediately start the auxiliary heating according to the actual situation.

[0084] Example 3

[0085] On the basis of Example 1, further, after starting the range extender to assist heating when it is determined that the first water temperature difference is less than the first preset threshold, the following steps are further included:

[0086] Get the third real-time temperature of the outdoor environment;

[0087] When it is determined that the third real-time temperature is greater than or equal to a fourth preset threshold, turning off the auxiliary heating of the range extender;

[0088] After the vehicle has been traveling for a period of time, the outdoor environment in which it is located will also change, and the temperature of the outdoor environment will also change. The third real-time temperature is the outdoor environment temperature after the vehicle has been traveling for a period of time, which is measured by a temperature sensor located in the front engine compartment of the vehicle; wherein, the fourth preset threshold is the outdoor environment temperature that does not affect the driving experience of the passengers, and can be set to -10°C in actual application. If the third real-time temperature is measured to be -5°C, which is greater than the fourth preset threshold, the auxiliary heating of the range extender is turned off. The setting of this strategy can avoid excessive operation of the range extender, thereby reducing energy consumption and improving economy.

[0089] Example 4

[0090] On the basis of Example 1, further, after starting the range extender to assist heating when it is determined that the first water temperature difference is less than the first preset threshold, the following steps are further included:

[0091] Obtain the third real-time water temperature in the water path of the air conditioning system;

[0092] querying the first database to obtain a third target water temperature corresponding to the current air conditioner set temperature;

[0093] calculating a difference between the third real-time water temperature and the third target water temperature to obtain a fourth water temperature difference;

[0094] When it is determined that the fourth water temperature difference is greater than or equal to a seventh preset threshold, turning off the range extender auxiliary heating;

[0095] Among them, the first real-time water temperature is measured by a temperature sensor provided in the water circuit of the air-conditioning system; if the current occupant sets the target temperature to 25°C according to his or her own needs, the corresponding first target water temperature at this time is 70°C according to Table 1; if the third real-time water temperature obtained at this time is 68°C, the fourth water temperature difference is calculated to be -2°C, among which the seventh preset threshold is the minimum water temperature difference to ensure the driving comfort of the passenger compartment, which can be set to -4°C. At this time, if the fourth water temperature difference is greater than the seventh preset threshold, the auxiliary heating of the range extender is turned off; the setting of this strategy can avoid excessive operation of the range extender, thereby reducing energy consumption and improving economy.

[0096] Example 5

[0097] On the basis of Example 1, further, after starting the range extender to assist heating when it is determined that the first water temperature difference is less than the first preset threshold, the following steps are further included:

[0098] In response to an input signal indicating that the air conditioning set temperature has decreased, a difference between target water temperatures corresponding to the air conditioning set temperatures before and after the change is calculated to obtain a fifth water temperature difference;

[0099] When it is determined that the absolute value of the fifth water temperature difference is greater than or equal to an eighth preset threshold, obtaining a fourth real-time water temperature in the water path of the air-conditioning system;

[0100] querying the first database to obtain a fourth target water temperature corresponding to the current air conditioner set temperature;

[0101] calculating a difference between the fourth real-time water temperature and the fourth target water temperature to obtain a sixth water temperature difference;

[0102] When it is determined that the sixth water temperature difference is greater than or equal to a ninth preset threshold, controlling the second timer to start timing;

[0103] When it is determined that the timing time of the second timer is greater than or equal to the second preset time length, turning off the range extender auxiliary heating;

[0104] During vehicle driving, when the passenger lowers the air conditioning set temperature from 25°C to 23°C according to his own needs, the fifth water temperature difference is -13°C according to Table 1. At this time, the absolute value of the fifth water temperature difference is greater than the eighth preset threshold value, and it is necessary to perform the judgment of whether to turn off the range extender auxiliary heating in Example 4 again, wherein the eighth preset threshold value is equal to the third preset threshold value, and the ninth preset threshold value is equal to the seventh preset threshold value; after the condition for turning off the range extender auxiliary heating is met, the second timer is controlled to start timing, and the second preset time length is set to 3 0s, when the second timer reaches 30s, the auxiliary heating of the range extender is turned off; in this embodiment, a delayed shutdown judgment strategy is set for shutting down the auxiliary heating of the range extender, which can avoid giving passengers a negative impression that the range extender operates together with the adjustment of the air-conditioning panel and the confusion that the range extender cannot be turned off in pure electric mode; at the same time, when the air-conditioning set temperature suddenly drops due to an accidental touch by a passenger, the delay strategy can also provide the passenger with a certain amount of adjustment time; in addition, when the target temperature water temperature difference change is less than the third preset threshold, the range extender can immediately shut down the auxiliary heating according to the actual situation.

[0105] In addition, when it is determined that the absolute value of the fifth water temperature difference is greater than the eighth preset threshold, the determination of whether to turn off the range extender auxiliary heating in Example 3 may be performed again; it is only necessary to meet the determination conditions of either Example 3 or Example 4 to determine the delayed turn off of the range extender auxiliary heating.
