However, the greatest disadvantage of PTC is electricity consumption, for example, in a certain vehicle type, the sum of the power of two PTC on the vehicle is 9.2 kw, if the two PTC are heated at rated power, 9.2 degrees of electricity is consumed in one hour, and if a 70 degree power battery pack is mounted on the vehicle, about 13% of the electricity is consumed in one hour, and the electricity consumption is still relatively large. Because the PTC heater has higher power, the PTC heater is turned on when mixed with warm air under the refrigeration working condition, so that the PTC heater has higher energy consumption, and the problems of energy waste and energy saving are solved.

Based on the above problems, the embodiment of the application provides an air conditioner temperature control method, which specifically comprises the following implementation processes: and under the condition that the current air conditioner working mode of the vehicle is refrigeration and the actual air outlet temperature of the current air conditioner of the vehicle is smaller than the target air outlet temperature, controlling the air conditioner warm air loop to be communicated with the heating loop so that the actual air outlet temperature is equal to the target air outlet temperature. According to the air conditioner, when the air conditioner working mode of the current vehicle is refrigeration and the actual air outlet temperature of the current vehicle air conditioner is smaller than the target air outlet temperature, namely, the air conditioner warm air loop and the heating loop are controlled to be communicated when the requirement of mixing warm air under refrigeration working conditions is met, namely, heat generated by the existing heating loop in the vehicle is introduced into the air conditioner warm air loop, the air conditioner warm air loop is heated to generate warm air, the actual air outlet temperature is improved by utilizing the heat generated by the existing heating loop in the vehicle, an additional PTC heater is not needed, the part of energy consumption required by heating by the PTC heater is saved, and the technical problem that the energy consumption of the vehicle air conditioner is high is solved.

Referring to fig. 1, fig. 1 is a schematic flow chart of an air conditioner temperature control method according to an embodiment of the present application, where the air conditioner temperature control method includes the following steps:

step 101, controlling the air-conditioning warm air loop to be communicated with the heating loop so that the actual air-out temperature is equal to the target air-out temperature under the condition that the current air-conditioning working mode of the vehicle is refrigeration and the actual air-out temperature of the current air-conditioning of the vehicle is smaller than the target air-out temperature.

In the embodiment of the application, when the actual air outlet temperature is the actual air outlet temperature of the air outlet of the air conditioner under the lowest rotation speed when the current air conditioner working mode of the vehicle is refrigeration; the actual air outlet temperature can be obtained through a temperature sensor at the air outlet of the air conditioner.

The target air outlet temperature is the air outlet temperature requested by the controller, and the controller calculates the ideal temperature according to the air conditioner temperature set by the driver or the passenger on the air conditioner control panel in the passenger cabin and the relevant environment data inside and outside the vehicle, so that the body sensing temperature of the driver or the passenger can reach the air conditioner temperature set by the user.

After the actual air-out temperature and the target air-out temperature are obtained, the controller compares the actual air-out temperature with the target air-out temperature and judges whether the actual air-out temperature is smaller than the target air-out temperature.

If it is determined that the current air conditioning operation mode of the vehicle is refrigeration and the actual air outlet temperature is less than the target air outlet temperature, for example: the actual air outlet temperature of the air conditioner air outlet is 8 degrees under the lowest rotating speed, the target air outlet temperature is 10 degrees, and the actual air outlet temperature of the air conditioner air outlet is still lower than the target air outlet temperature under the lowest rotating speed, which indicates that warm air is mixed under the refrigerating working condition at the moment to meet the air conditioner temperature set by a driver or a passenger. The specific implementation process of mixing warm air under the refrigeration working condition is as follows: the heating loop of the air conditioner is controlled to be communicated with the heating loop, and the loop obtained after the communication is the target loop, so that heat generated by the existing heating loop in the vehicle is introduced into the heating loop of the air conditioner; acquiring a target loop temperature based on the target loop; and executing a corresponding control strategy based on the numerical relation between the target loop temperature and a preset second temperature threshold value, so that the actual air outlet temperature of the air outlet of the air conditioner is equal to the target air outlet temperature, and the air conditioner temperature requirement set by a user is met.

According to the air conditioner, when the air conditioner working mode of the current vehicle is refrigeration and the actual air outlet temperature of the current vehicle air conditioner is smaller than the target air outlet temperature, namely, the air conditioner warm air loop and the heating loop are controlled to be communicated when the requirement of mixing warm air under refrigeration working conditions is met, namely, heat generated by the existing heating loop in the vehicle is introduced into the air conditioner warm air loop, the air conditioner warm air loop is heated to generate warm air, the actual air outlet temperature is improved by utilizing the heat generated by the existing heating loop in the vehicle, an additional PTC heater is not needed, the part of energy consumption required by heating by the PTC heater is saved, and the technical problem that the energy consumption of the vehicle air conditioner is high is solved.

Further, in the embodiment of the present application, before step 101, the following steps may be further included:

wherein, judge whether the air conditioner mode of current vehicle is refrigeration, include:

In the embodiment of the present application, it is first necessary to determine whether the current air conditioning operation mode of the vehicle is cooling.

The specific process for judging whether the current air conditioner working mode of the vehicle is refrigeration or not is as follows: acquiring the current outside temperature, the inside-outside circulation proportion of an air conditioner, the current illumination intensity, the air conditioner temperature set by a user and the current inside temperature of the vehicle; the obtained current outside temperature, the inside-outside circulation proportion of the air conditioner, the current illumination intensity, the air conditioner temperature set by a user and the current inside-vehicle temperature are input into an energy value calculation model in the controller, and the energy value is output after the energy value calculation model is processed; determining whether the current air-conditioning operation mode of the vehicle is cooling or heating according to the energy value and the preset energy value interval, for example: if the energy value output by the energy value calculation model is Z, the energy value interval is (0-1000), the (0-X) is a preset refrigerating interval, the (Y-1000) is a preset heating interval, the (X-Y) is a hysteresis zone, and the (Z-X) is a refrigerating air mixing interval; if Z is more than 0 and less than X, indicating that the energy value is in a preset refrigeration interval, and the current air conditioner working mode of the vehicle is refrigeration; if Y is smaller than Z and smaller than 1000, the energy value is in a preset heating interval, and the current air conditioner working mode of the vehicle is heating.

The energy value calculation model is a model used for calculating an energy value in the controller, and can be used for determining the energy value according to the current first temperature parameter of the vehicle, so that whether the current air conditioner working mode of the vehicle is refrigeration or not can be judged according to the energy value and a preset energy value interval.

wherein, obtain target air-out temperature, include:

acquiring a current second temperature parameter of the vehicle, wherein the current second temperature parameter comprises a current outside temperature, a current illumination intensity, the air quantity of a current air conditioner blower, an air conditioner temperature set by a user and a current inside temperature;

It should be noted that, in the embodiment of the present application, the target air outlet temperature needs to be obtained, so as to determine whether the actual air outlet temperature of the current vehicle air conditioner is less than the target air outlet temperature.

The specific process for acquiring the target air outlet temperature comprises the following steps: acquiring the current outside temperature, the current illumination intensity, the current air quantity of an air conditioner blower, the air conditioner temperature set by a user and the current inside temperature; the obtained current outside temperature, current illumination intensity, current air quantity of an air conditioner blower, air conditioner temperature set by a user and current inside temperature are input into a temperature value calculation model in the controller, the temperature value is output after the processing of the temperature value calculation model, and the output temperature value can be determined to be the target air outlet temperature.

The temperature value calculation model is a model for calculating the target air outlet temperature in the controller, and can determine the target air outlet temperature according to the current second temperature parameter of the vehicle, so that whether the current vehicle air conditioner needs warm air mixing or not can be judged according to the target air outlet temperature and the actual air outlet temperature.

Further, in the embodiment of the present application, as shown in fig. 2, before the step of controlling the air conditioning heating circuit to communicate with the heating circuit in step 101 is performed, the following steps may be further included:

in step 201, a heating circuit temperature is obtained.

Step 202, determining whether the heating circuit temperature is greater than a preset first temperature threshold.

And 203, controlling the air-conditioning warm air loop to be communicated with the heating loop under the condition that the temperature of the heating loop is greater than a first temperature threshold.

It should be noted that, in the embodiment of the present application, the heating circuit temperature includes a motor circuit temperature, a battery circuit temperature, and an engine circuit temperature; when the vehicle type configuration information of the current vehicle is a pure electric vehicle, namely the current vehicle is a pure electric vehicle, the heating loop can be a motor loop or a battery loop, and then the temperature of the heating loop can be the temperature of the motor loop or the temperature of the battery loop; when the vehicle type configuration information of the current vehicle is a hybrid vehicle type, that is, the current vehicle is a hybrid vehicle, the heating loop may be an engine loop, a motor loop or a battery loop, and then the heating loop temperature may be any one of an engine loop temperature, a motor loop temperature and a battery loop temperature.

Steps 201-203 may be implemented by direct control of one controller or may be implemented by indirect control of data interaction between two controllers.

The specific implementation process directly controlled by one controller is as follows: the controller is used for controlling and acquiring the heating loop temperature, and after the heating loop temperature is acquired, the controller is used for directly comparing the heating loop temperature with a preset first temperature threshold value and judging whether the heating loop temperature is larger than the preset first temperature threshold value, wherein the first temperature threshold value is larger than the target air outlet temperature, and the first temperature threshold value is calibrated in advance and used for judging whether the heating loop temperature can reach the condition of meeting the target air outlet temperature. If the temperature of the heating loop is greater than a preset first temperature threshold value, the condition that the temperature of the heating loop can meet the target air outlet temperature is indicated, namely, the temperature of the heating loop can be recycled at the moment, and the controller controls the air conditioner warm air loop to be communicated with the heating loop; if the heating loop temperature is less than or equal to the preset first temperature threshold, the heating loop temperature cannot meet the condition of meeting the target air outlet temperature, namely, the heating loop temperature does not need to be recycled, and further, the controller does not need to execute subsequent steps.

The specific implementation process of indirect control through data interaction between the two controllers is as follows: the first controller is used for controlling the circulation of cooling liquid in the air conditioning warm air loop, the second controller is used for controlling the circulation of cooling liquid in the heating loop, and the second controller is also used for controlling the connection and disconnection of the air conditioning warm air loop and the heating loop. The first controller sends a heating circuit temperature acquisition request to the second controller, the heating circuit temperature acquisition request being used to request acquisition of the heating circuit temperature. The heating loop temperature acquisition request comprises a motor loop temperature acquisition request, a battery loop temperature acquisition request and an engine loop temperature acquisition request; when the vehicle type configuration information of the current vehicle is a pure electric vehicle, namely the current vehicle is a pure electric vehicle, the heating loop temperature acquisition request can be a motor loop temperature acquisition request and/or a battery loop temperature acquisition request; the motor loop temperature acquisition request is used for requesting to acquire the existing motor loop temperature in the pure electric vehicle, and the battery loop temperature acquisition request is used for requesting to acquire the existing battery loop temperature in the pure electric vehicle; when the vehicle type configuration information of the current vehicle is a hybrid vehicle type, that is, the current vehicle is a hybrid vehicle, the heating loop temperature acquisition request may be at least one of an engine loop temperature acquisition request, a motor loop temperature acquisition request, and a battery loop temperature acquisition request, where the engine loop temperature acquisition request is used for requesting acquisition of an existing engine loop temperature inside the hybrid vehicle, the motor loop temperature acquisition request is used for requesting acquisition of an existing motor loop temperature inside the hybrid vehicle, and the battery loop temperature acquisition request is used for requesting acquisition of an existing battery loop temperature inside the hybrid vehicle.

The first controller receives the heating loop temperature sent by the second controller, compares the heating loop temperature with a preset first temperature threshold after receiving the heating loop temperature sent by the second controller, and judges whether the heating loop temperature is greater than the preset first temperature threshold, wherein the first temperature threshold is greater than the target air outlet temperature, and the first temperature threshold is calibrated in advance and used for judging whether the heating loop temperature can reach the condition of meeting the target air outlet temperature.

If the temperature of the heating loop is greater than a preset first temperature threshold, the condition that the temperature of the heating loop can meet the target air outlet temperature is indicated, namely, the temperature of the heating loop can be recycled at the moment, and the air conditioning warm air loop is controlled to be communicated with the heating loop through a second controller; if the heating loop temperature is less than or equal to the preset first temperature threshold, the heating loop temperature cannot meet the condition of meeting the target air outlet temperature, namely, the heating loop temperature does not need to be recycled, and further, the second controller does not need to execute subsequent steps.

Further, in the embodiment of the present application, when the vehicle type configuration information of the current vehicle is a pure electric vehicle type, the heating circuit is a motor circuit or a battery circuit, or may be a motor circuit and a battery circuit, that is, the heating circuit includes two circuits;

It should be noted that, in the embodiment of the present application, when the vehicle type configuration information of the current vehicle is a pure electric vehicle, that is, the current vehicle is a pure electric vehicle, the heating circuit is a motor circuit or a battery circuit; the motor loop can be a loop formed by sequentially and circularly connecting a motor, a motor water pump, a three-way valve, a radiator and the motor; the battery loop can be a loop formed by sequentially and circularly connecting a battery, a three-way valve, a radiator, a battery water pump and the battery. When the vehicle type configuration information of the current vehicle is a hybrid vehicle type, namely the current vehicle is a hybrid electric vehicle, the heating loop is one or more loops of an engine loop, a motor loop and a battery loop; the engine loop can be a loop formed by sequentially and circularly connecting an engine, a motor water pump, a three-way valve, a radiator and the engine, and the motor loop and the battery loop are the same as the pure electric vehicle.

According to the method and the device, when the current vehicle is a pure electric vehicle, heat generated by the existing motor loop or the existing battery loop in the vehicle can be utilized to heat the air so as to generate warm air, when the current vehicle is a hybrid vehicle, heat generated by the existing engine loop or the existing motor loop or the existing battery loop in the vehicle can be utilized to heat the air so as to generate warm air, and therefore energy-saving requirements of all new energy vehicles can be met, and driving experience of a user is improved.

Further, in the embodiment of the present application, as shown in fig. 3, after the step of controlling the air conditioning heating circuit to communicate with the heating circuit in the step 101 is performed, the following steps may be further included:

Step 304, if the target loop temperature is less than or equal to the second temperature threshold, a heating start request is sent to the heater.

In step 305, if the target loop temperature is greater than the second temperature threshold, the opening percentage of the air conditioner is controlled and adjusted.

In the embodiment of the present application, the target circuit can be obtained after the heating circuit and the air conditioning and heating circuit are connected.
