[0044] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0045] The vehicle heating method provided in this application can be applied to environments where vehicles are heated. Specifically, it can be used to select different heating methods based on ambient temperature data and vehicle operating data to reduce energy consumption for vehicle heating. This method can be executed by an air conditioning controller.

[0046] See also Figure 1 , Figure 1A system structure diagram for vehicle heating is provided, which mainly includes a cab air conditioning heating device, an electric air conditioning compressor, a water-heated fuel heating device, a water-cooled condenser, valves, pipelines, control units, etc. Figure 1 The diagram illustrates the available heating methods for the driver's cab. Specifically, the available heating methods include fuel heating, heat pump heating, and positive temperature coefficient (PTC) heating. The target heating method can be determined based on ambient temperature data and vehicle operating data, and then used to reduce energy consumption for vehicle heating.

[0047] See also Figure 2 , Figure 2 A schematic diagram of vehicle heating is provided. The vehicle controller feeds back ambient temperature data and vehicle operation data to the air conditioning controller. The vehicle operation data includes at least battery charge parameters, battery water temperature parameters, and motor cooling water temperature parameters, so that the air conditioning controller can select an appropriate target heating method based on the ambient temperature data and vehicle operation data, and control the opening and closing of the corresponding water valves to achieve the coupling of heat from the battery, motor, and cab water circuit to achieve the heating purpose.

[0048] In one embodiment, such as Figure 3 As shown, a vehicle heating method is provided. Taking the application of this method to an air conditioning controller as an example, the method includes the following steps:

[0049] S301, obtain vehicle data.

[0050] For example, the vehicle can be a new energy vehicle, specifically a new energy commercial vehicle. The vehicle controller can feed back vehicle data to the air conditioning controller, wherein the vehicle data includes at least one of the following: battery operating condition data, motor temperature data, and ambient temperature data of the environment in which the vehicle is located. Among them, the battery operating condition data includes the remaining battery charge (SOC) and battery temperature data.

[0051] S302, based on vehicle data, selects the target heating method from fuel heating, heat pump heating, and positive temperature coefficient (PTC) heating.

[0052] For example, a correspondence between vehicle data and heating methods can be established in advance, or a target heating method can be determined based on vehicle data according to a preset algorithm; wherein, the target heating method can be one or more of fuel heating, heat pump heating and PTC heating.

[0053] The S303 uses a targeted heating method to heat the vehicle.

[0054] Furthermore, a targeted heating method can be used to heat the vehicle. For example, if the heating requirement is for the cab, a targeted heating method can be used to heat the cab; if the heating requirement is for the battery, a targeted heating method can be used to heat the battery.

[0055] The aforementioned vehicle heating method acquires at least one of the following data: battery operating condition data, motor temperature data, and ambient temperature data of the vehicle's surroundings. Based on the acquired data, a target heating method is selected from fuel heating, heat pump heating, and PTC heating. This target heating method is then used to heat the vehicle. This approach can identify the target heating method with higher energy efficiency under the corresponding operating conditions of the acquired data, and using this method to heat the vehicle can reduce energy consumption for vehicle heating.

[0056] In some optional implementations, embodiments of this application can analyze the energy utilization rate of different heating methods under the same vehicle data based on vehicle test data. For example, under the same ambient temperature and the same battery SOC, the energy utilization rate of different heating methods can be compared, and the heating method with the highest energy utilization rate can be selected as the target heating method corresponding to the vehicle data. This completes the calibration of the vehicle data and the target heating method.

[0057] Following the calibration method described above, all possible vehicle data can be traversed to find the target heating method that corresponds one-to-one with different vehicle data, thus establishing a correspondence between vehicle data and target heating methods. Therefore, after obtaining the current vehicle data, the corresponding target heating method can be determined based on the pre-established correspondence.

[0058] For example, refer to Table 1, which shows an example of the pre-established correspondence between vehicle data and target heating methods. Assume the ambient temperature range of the vehicle is -25℃ to 10℃, and the calibrated correspondence between vehicle data and target heating methods is shown. In the table, "●" indicates that the heating method is selected; "○" indicates that the heating method is selected based on conditions, for example, under this ambient temperature data, further determination of whether to select this heating method is needed based on battery SOC or motor temperature data; "X" indicates that the heating method is not selected.

[0059] Table 1:

[0060]

[0061] It should be noted that Table 1 above is only an illustrative example of vehicle data and is not intended to limit the vehicle data. For vehicle data not shown, the above calibration method can also be used to establish the correspondence between vehicle data and target heating methods.

[0062] Based on this, the embodiments of this application provide a first implementation process for determining the target heating method based on vehicle data, the specific implementation process is as follows:

[0063] If the ambient temperature data is within the first temperature range and the battery charge in the battery status data is within the first charge range, then the heat pump heating method will be used as the target heating method.

[0064] For example, the first temperature range can be -5℃ to 10℃, and the first power range can be [E%, 100%], where E% can be determined based on empirical data, and E% is used to represent the critical value at which the remaining power of the battery meets the heating requirements of the heat pump.

[0065] If the ambient temperature data is within the first temperature range, and the battery charge level in the battery status data is within the first charge level range, then the heat pump heating method can be used as the target heating method. It should be noted that the first temperature range and the corresponding target heating method within the first charge level range can be determined using the above calibration method. This heating method is the one with the highest energy utilization rate within both the first temperature range and the first charge level range. Based on the pre-calibrated correspondence, the target heating method can then be determined. The air conditioning controller can then start the air conditioning compressor and control the opening and closing of the water circuit valves to achieve the air source heat pump heating function in the cab. Specifically, the air conditioning controller can control the compressor speed and valves according to the real-time temperature and target temperature requirement of the cab to meet the heating needs of the cab.

[0066] Based on the correspondence, the target heating method is determined to be heat pump heating. This means that when the ambient temperature is high and the battery power is sufficient, using heat pump heating to heat the vehicle's cab is more energy efficient, thereby reducing the energy consumption for vehicle heating.

[0067] If the ambient temperature data is in the first temperature range and the battery charge in the battery condition data is in the second charge range, then the fuel heating method will be used as the target heating method.

[0068] Furthermore, the second energy range can be [0%, E%), where the second energy range is less than the first energy range. If the ambient temperature data is within the first temperature range and the battery charge in the battery status data is within the second energy range, then fuel heating will be the target heating method. At this time, the air conditioning controller can stop the heat pump heating and start the water-fuel heating system to heat the cab. The air conditioning controller controls the combustion power of the water-fuel heater and the opening and closing of the water valves according to the real-time temperature inside the cab and the set target temperature, thereby enabling the water-fuel heating system to heat the cab.

[0069] This means that if the ambient temperature is high and the battery power is insufficient to support the heat pump for heating, then fuel heating can be used to heat the vehicle. In this case, using fuel heating to heat the vehicle's cab is more energy efficient, thereby reducing the energy consumption for vehicle heating.

[0070] In this embodiment of the application, a method is provided to determine the target heating method by combining the remaining battery charge when the ambient temperature data is high, so that the determined heating method consumes less energy for vehicle heating.

[0071] In some optional implementations, embodiments of this application provide a second implementation process for determining the target heating method based on vehicle data, the specific implementation process of which is as follows:

[0072] If the ambient temperature data is in the second temperature range, the battery charge in the battery status data is in the first charge range, and the motor temperature data is in the third temperature range, then the heat pump heating method will be used as the target heating method.

[0073] For example, the second temperature range can be -25℃ to -5℃, meaning the second temperature range is shorter than the first temperature range. In this case, the vehicle is considered to be in a low-temperature environment, increasing the heating demand in the cab. The air-source heat pump system, however, draws less heat from the outside air and can no longer meet the cab's heating needs. Therefore, the target heating method can be further determined based on the remaining battery charge and motor temperature data.

[0074] Specifically, the third temperature range can be a temperature range greater than or equal to T1, where T1 can be determined based on empirical data. T1 can be understood as the critical value at which the motor's water circuit temperature meets the heating requirements. Therefore, if the ambient temperature data is in the second temperature range, the battery charge data is in the first charge range, and the motor temperature data is in the third temperature range, then the heat pump heating method can be used as the target heating method, as it is considered to have higher energy efficiency in this case. Specifically, the water source heat pump mode can be run, the motor water circuit control valve can be opened, and the compressor speed and valves can be controlled according to the real-time temperature of the cab and the set target temperature to achieve heating of the cab.

[0075] If the ambient temperature data is in the second temperature range, the battery charge in the battery status data is in the first charge range, and the motor temperature data is in the fourth temperature range, then the heat pump heating method and the PTC heating method will be used as the target heating methods.

[0076] In this situation, it can be assumed that the water source heat pump cannot meet the heating demand. At this time, the air conditioning controller executes the water source heat pump + PTC compensation heating mode. The PTC is an electric heating device, integrated into the air conditioning unit and stacked parallel to the warm air heater. The air conditioning controller controls the compressor speed, valve opening, and PTC operating power according to the real-time temperature of the cab and the set target temperature to achieve heating of the cab.

[0077] Furthermore, the fourth temperature range can be understood as [0, T1), meaning the third temperature range is greater than the fourth temperature range. That is, if the ambient temperature data is in the second temperature range, the battery charge data is in the first charge range, and the motor temperature data is in the fourth temperature range, it is considered that the motor's water temperature does not meet the heating requirements. In this case, heat pump heating and PTC heating can be used as the target heating methods, meaning that both heat pump heating and PTC heating are used together to heat the vehicle's cab.

[0078] In this embodiment of the application, a method is provided to determine the target heating method by combining the remaining battery charge and motor temperature data when the ambient temperature is low, so that the determined heating method consumes less energy for vehicle heating.

[0079] Furthermore, if the ambient temperature data is within the second temperature range, and the battery charge level in the battery status data is also within the second charge range, it is assumed that in a low-temperature environment, the remaining battery charge is insufficient to support the heat pump heating method to meet the heating demand. Therefore, fuel heating can be chosen as the target heating method. In this case, to ensure the vehicle can start and run normally, the air conditioning controller can stop the water source heat pump heating + PTC compensated heating and start the water-fuel heating system to heat the cab. The air conditioning controller controls the combustion power of the water-fuel heater and the opening and closing of the water valves based on the real-time temperature inside the cab and the set target temperature, thus enabling the water-fuel heating system to heat the cab. In this case, fuel heating is considered to have higher energy efficiency, and therefore can be chosen as the target heating method, thereby reducing energy consumption for heating the vehicle's cab.

[0080] In some optional implementations, this application provides a third implementation process for determining the target heating method based on vehicle data, the specific implementation process of which is as follows:

[0081] If the ambient temperature data is in the fifth temperature range and the battery charge in the battery condition data is in the first charge range, then fuel heating and PTC heating will be used as the target heating methods.

[0082] For example, the fifth temperature range can be a range less than -25°C, meaning the fifth temperature range is less than the second temperature range; in this case, the vehicle is considered to be in an extremely low temperature environment. That is, if the ambient temperature data is in the fifth temperature range and the battery charge in the battery condition data is in the first charge range, then fuel heating and PTC heating can be used as the target heating methods.

[0083] In environments with temperatures below -25°C, the heating demand in the cab continues to increase, the heating efficiency of the water source heat pump system decreases, and PTC-compensated heating can no longer meet the cab's heating needs. At this time, the air conditioning controller can operate in fuel-fired heating mode + PTC auxiliary heating, opening the fuel-fired heating water circuit control valve and controlling the heating power of the fuel-fired heating device based on the real-time cab temperature and the set target temperature. PTC auxiliary heating is activated because the air conditioning controller needs time to raise the temperature of the fuel-fired heating water circuit; this ensures sufficient heat in the cab to meet defrosting and defogging requirements. When the fuel-fired heating system water circuit temperature > T2, the air conditioning control unit stops operating PTC auxiliary heating and only operates the fuel-fired heating system to save energy. It should be noted that T2 is greater than T1; T2 can be understood as the critical temperature for defrosting and defogging in the cab.

[0084] In this case, it is believed that using fuel heating and PTC heating to heat the vehicle's cab consumes less energy.

[0085] If the ambient temperature data is in the fifth temperature range and the battery charge in the battery condition data is in the second charge range, then the fuel heating method will be used as the target heating method.

[0086] Furthermore, if the ambient temperature data is in the fifth temperature range and the battery charge level in the battery condition data is in the second charge range, then fuel heating can be used as the target heating method. In this case, it is believed that using fuel heating to heat the vehicle's cabin consumes less energy.

[0087] In this embodiment of the application, a method is provided to determine the target heating method by combining the remaining battery power when the ambient temperature data is at an extremely low temperature, so that the determined heating method consumes less energy for vehicle heating.

[0088] In some optional implementations, the battery can also be heated. For example, if the battery cell temperature in the battery operating data is lower than a temperature threshold, then fuel heating can be used as the target heating method. The temperature threshold can be set based on empirical data and is used to characterize the critical battery cell temperature value for maintaining battery performance. That is, when the battery cell temperature is lower than the temperature threshold, the battery performance will degrade. Therefore, fuel heating can be used to heat the vehicle's battery, for example, by adjusting the heating power of the fuel heater to meet the battery's low-temperature heating requirements, thereby ensuring battery performance and reducing the energy consumed in heating the battery, thus improving energy utilization efficiency.

[0089] This application embodiment, through analysis of the aforementioned vehicle data, achieves the functions of cab heating and battery heating. The air conditioning controller controls the opening and closing of the water circuit shut-off valve to realize the operation of different heating systems and water circuit coupling; enabling the vehicle to obtain heat in the most energy-efficient way under different ambient temperatures, solving the problems of poor air conditioning heating effect and high energy consumption and slow battery heating speed of new energy vehicles in extremely cold and harsh environments, improving energy utilization efficiency, and thus increasing the vehicle's winter driving range.
