DETAILED DESCRIPTION

[0020] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0021] Reference Figure 1 , shows a flow chart of the steps of a vehicle external temperature simulation method provided in an embodiment of the present invention, wherein the vehicle is equipped with at least one sensor and components, and specifically comprises the following steps: Step 101: Acquire sensor data collected by the sensor and component status of the component; the sensor data is used to determine at least one sensor temperature of the vehicle.

[0022] In practical applications, a vehicle is usually equipped with at least one sensor and components, usually multiple sensors. For example, the sensor may include a temperature sensor, a pressure sensor, a speed sensor, etc., and the components may include a cooling fan, a compressor, and a battery, etc.

[0023] In an embodiment of the present invention, sensor data collected by sensors on the vehicle can be obtained. Exemplarily, the sensor data may include at least engine water temperature, motor water temperature, high pressure pressure of the refrigerant system, low pressure pressure of the refrigerant system, temperature of the refrigerant system and vehicle speed, wherein the refrigerant system is a refrigeration cycle system in vehicle thermal management, and core components may include compressors, condensers, expansion valves and evaporators, etc., and the phase change characteristics of the refrigerant (refrigerant) are used to absorb the heat of the passenger compartment or battery to achieve temperature control. The high pressure pressure of the refrigerant system is the high pressure side pressure of the refrigerant before the compressor outlet to the expansion valve, reflecting the heat dissipation efficiency of the condenser, and the low pressure pressure of the refrigerant system is the low pressure side pressure of the refrigerant from the evaporator outlet to the compressor inlet, reflecting the heat absorption capacity of the evaporator; the high pressure pressure of the refrigerant system has a corresponding refrigerant temperature, and the low pressure pressure of the refrigerant system has a corresponding refrigerant temperature, and the refrigerant system temperature is the temperature of the low-temperature and low-pressure gaseous refrigerant collected by the temperature sensor installed on the low-pressure side of the refrigeration cycle (usually located at the evaporator outlet or the compressor suction line). For ease of explanation, in the subsequent description, the engine water temperature, motor water temperature, refrigerant system temperature, refrigerant system high pressure with corresponding refrigerant temperature and refrigerant system low pressure with corresponding refrigerant temperature are collectively referred to as sensor temperature.

[0024] In an embodiment of the present invention, the component status corresponding to the components on the vehicle can also be obtained, and the component status may include at least the compressor status, the cooling fan status and the battery cooling status; wherein the compressor status may include at least the speed of the compressor; the cooling fan status may include at least the speed of the cooling fan; the battery cooling status may include at least the battery cooling strategy on and the battery cooling strategy off. Specifically, when the battery cooling strategy is turned on, components such as the electric water pump and the cooling fan on the vehicle may be started to perform thermal management on the battery.

[0025] Step 102, obtaining the memory external temperature of the vehicle obtained in the last simulation; Step 103, obtaining at least one temperature range of the vehicle; the temperature range has corresponding processing logic; Step 104, taking the minimum value of the sensor temperatures as the target temperature; Step 105: taking the temperature range in which the difference between the memorized external temperature and the target temperature falls as the target temperature range; Step 106: Simulate the external temperature of the vehicle according to the processing logic corresponding to the target temperature range, the sensor data, and the component status.

[0026] In an embodiment of the present invention, after obtaining sensor data and component status, these data can be combined to simulate the external temperature of the vehicle, and then the simulated external temperature can be displayed on the vehicle's on-board terminal, or the vehicle can be controlled based on the external temperature. For example, when the external temperature of the vehicle is too high, the speed of the compressor of the vehicle's air-conditioning system can be increased, or the speed of the cooling fan can be increased.

[0027] In some cases, some vehicles do not install temperature sensors outside the vehicle to measure the external temperature due to cost and other factors, or when a temperature sensor installed outside the vehicle fails, the external temperature of the vehicle can be simulated through sensor data and component status. Since the vehicle according to the embodiment of the present invention does not need to be equipped with a separate external temperature sensor, the manufacturing cost of the entire vehicle can be reduced and will not be affected by the layout position of the external temperature sensor, the thermal radiation of the radiator, etc., thereby ensuring the accuracy of the obtained external temperature.

[0028] In an embodiment of the present invention, the external temperature of the vehicle obtained by the last simulation can be obtained as the memory external temperature, and the external temperature of the vehicle can be jointly simulated based on the memory external temperature, sensor data and component status.

[0029] In some embodiments, when there is no memory external temperature of the vehicle obtained by the previous simulation, for example, when the external temperature simulation of the vehicle is started for the first time, the minimum value of the sensor temperature can be used as the memory external temperature, that is, from the engine water temperature, motor water temperature, refrigerant system temperature, refrigerant system high pressure with corresponding refrigerant temperature and refrigerant system low pressure with corresponding refrigerant temperature, the minimum value is selected as the memory external temperature, which is used to simulate the external temperature of the vehicle in conjunction with the sensor data and component status. In the above embodiment, the external temperature of the vehicle can be simulated in conjunction with the memory external temperature, sensor data and component status, so as to simulate and obtain an accurate external temperature.

[0030] In a specific implementation, at least one temperature range is pre-set for the vehicle, and each temperature range has a corresponding processing logic, wherein the processing logic may include a speed threshold and a duration threshold. It should be noted that the temperature range can be made into multiple or different temperature ranges according to different vehicle models or different needs, for example, there may be three temperature ranges TS1, TS2, and TS3. The embodiment of the present invention does not need to be limited to this.

[0031] In an embodiment of the present invention, the minimum value of the sensor temperature can be used as the memorized external temperature, that is, from the sensor temperatures of the engine water temperature, the motor water temperature, the refrigerant system temperature, the refrigerant system high pressure with the corresponding refrigerant temperature and the refrigerant system low pressure with the corresponding refrigerant temperature, the minimum value is screened out as the target temperature, and then the temperature range interval into which the difference between the memorized external temperature and the target temperature falls is determined. Then, the external temperature of the vehicle can be jointly simulated according to the processing logic, sensor data and component status corresponding to the target temperature range interval.

[0032] In the above embodiment, the external temperature of the vehicle can be jointly simulated according to the processing logic, sensor data and component status corresponding to the target temperature range, so as to simulate and obtain the accurate external temperature.

[0033] In the above vehicle external temperature simulation method, the vehicle is equipped with at least one sensor and component, and the sensor data collected by the sensor and the component status of the component are obtained, wherein at least one sensor temperature of the vehicle can be determined according to the sensor data, and then the memory external temperature of the vehicle obtained by the last simulation can be obtained, and at least one temperature range interval of the vehicle can be obtained; the temperature range interval has a corresponding processing logic, the minimum value of the sensor temperature is taken as the target temperature, and then the temperature range interval into which the difference between the memory external temperature and the target temperature falls is taken as the target temperature range interval, and then the external temperature of the vehicle can be simulated according to the processing logic, sensor data and component status corresponding to the target temperature range interval. In the embodiment of the present invention, in the case where the vehicle is not equipped with a temperature sensor or the external temperature collected by the temperature sensor is inaccurate, the sensor data collected by the sensor already configured on the vehicle and the component status of the component can be used to jointly simulate the accurate external temperature of the vehicle, and the accurate external temperature can be obtained without increasing the hardware cost of the vehicle, so that a better vehicle environment can be provided for the driver of the vehicle based on the accurate external temperature.

[0034] In one embodiment of the present invention, simulating the external temperature of the vehicle according to the processing logic corresponding to the target temperature range, the sensor data and the component state includes: obtaining a rotation speed and a duration of a compressor of the vehicle; Obtaining a rotation speed threshold and a duration threshold in the processing logic corresponding to the target temperature range; An external temperature of the vehicle is simulated based on the speed, the duration, the speed threshold, the duration threshold, the sensor data, and the component status.

[0035] The processing logic may include a rotation speed threshold and a duration threshold.

[0036] In an embodiment of the present invention, after obtaining the processing logic corresponding to the target temperature range interval, the speed and duration of the vehicle's current compressor can be obtained, and then the vehicle's external temperature can be simulated based on the speed, duration, speed threshold, duration threshold, sensor data and component status.

[0037] In the above embodiment, the external temperature of the vehicle can be jointly simulated according to the rotation speed, duration, rotation speed threshold, duration threshold, sensor data and component status, so as to simulate and obtain the accurate external temperature.

[0038] In one embodiment of the present invention, simulating the external temperature of the vehicle according to the rotational speed, the duration, the rotational speed threshold, the duration threshold, the sensor data and the component state comprises: When the speed is less than the first speed threshold and the duration is less than the first duration threshold, and when the speed is greater than the second speed threshold and the duration is less than the second duration threshold, determining the target temperature as the external temperature of the vehicle; When the speed is less than the first speed threshold and the duration is greater than the first duration threshold, determining the external temperature of the vehicle according to the engine water temperature, the motor water temperature, the refrigerant system high pressure, the refrigerant system low pressure and a preset offset value; When the speed is greater than the second speed threshold and the duration is greater than the second duration threshold, the external temperature of the vehicle is determined based on the engine water temperature, the motor water temperature, the refrigerant system high pressure, the compensation value corresponding to the vehicle speed, the compensation value corresponding to the refrigerant system low pressure and the compensation value corresponding to the component status of the component.

[0039] The speed threshold may include a first speed threshold R1 and a second speed threshold R2, and R1 is less than R2; the duration threshold may include a first duration threshold t1 and a second duration threshold t2, and t1 is less than t2. TS represents the simulated external temperature. TN represents the target temperature, that is, the minimum value of the sensor temperature.

[0040] When the rotation speed is less than R1 and the duration is less than t1, and when the rotation speed is greater than R2 and the duration is less than t2, the target temperature may be determined as the external temperature of the vehicle, ie, TS=TN.

[0041] When the speed is less than R1 and the duration is greater than t1, the external temperature of the vehicle can be determined based on the engine water temperature, the motor water temperature, the refrigerant system high pressure, the refrigerant system low pressure and a preset offset value.

[0042] In some embodiments, determining the external temperature of the vehicle according to the engine water temperature, the motor water temperature, the high pressure of the refrigerant system, the low pressure of the refrigerant system and a preset offset value includes: Averaging the high pressure of the refrigerant system and the low pressure of the refrigerant system to obtain an average refrigerant system pressure; Determining a first candidate temperature according to the refrigerant temperature corresponding to the average refrigerant system pressure and a preset offset value; The minimum value among the engine water temperature, the motor water temperature and the first candidate temperature is determined as the external temperature of the vehicle.

[0043] Wherein, ΔT represents a preset offset value.

[0044] In a specific implementation, the refrigerant temperature corresponding to different pressures can be determined by statistically analyzing the pressure and refrigerant temperature of a large number of vehicles. In a specific embodiment, the calculation formula of the refrigerant temperature can be: Refrigerant temperature = -0.8826*(pressure / 1000)^6 + 9.5671*(pressure / 1000)^5 - 42.015*(pressure / 1000)^4 + 97.152*(pressure / 1000)^3 - 132.32*(pressure / 1000)^2 + 132.92*(pressure / 1000) -21.365.

[0045] The unit of pressure is kilopascal (kPa) and the unit of temperature is degree Celsius (℃).

[0046] In this way, after the pressure is determined, the refrigerant temperature corresponding to the pressure can be determined based on the above-mentioned calculation formula of the refrigerant temperature.

[0047] In an embodiment of the present invention, the preset offset value is a parameter used to correct the simulated external temperature, and is a fixed parameter. In practical applications, the external temperature obtained by multiple simulations and the actual external temperature can be statistically analyzed to obtain the preset offset value, so that when simulating the external temperature, the preset offset value can be used to correct the simulated external temperature, thereby improving the accuracy of the simulated external temperature. The compensation value is also a parameter used to correct the simulated external temperature, and is a dynamic parameter. In practical applications, the external temperature obtained by simulation and the actual external temperature can be analyzed at different vehicle speeds, refrigerant system low pressure pressures, and component states of components to determine the corresponding compensation values ​​at different vehicle speeds, refrigerant system low pressure pressures, and component states of components, wherein the corresponding compensation values ​​at different vehicle speeds, refrigerant system low pressure pressures, and component states of components can be stored in a table, so that when simulating the external temperature, the compensation values ​​corresponding to the current vehicle speed, refrigerant system low pressure pressure, and component state of components can be obtained by looking up the table, and then the simulated external temperature is compensated based on the compensation value, thereby improving the accuracy of the simulated external temperature.

[0048] In an embodiment of the present invention, the high pressure of the refrigerant system and the low pressure of the refrigerant system are averaged to obtain the average refrigerant system pressure, that is, the high pressure of the refrigerant system + the low pressure of the refrigerant system are summed and divided by 2 to obtain the average refrigerant system pressure. Then, the refrigerant temperature corresponding to the average refrigerant system pressure can be obtained. Combined with the refrigerant temperature and ΔT, a first candidate temperature is obtained, that is, the refrigerant temperature -ΔT corresponding to the average refrigerant system pressure. Then, the minimum value can be screened out from the water temperature (engine water temperature and motor water temperature) and the refrigerant temperature -ΔT corresponding to the average refrigerant system pressure and determined as the external temperature of the vehicle.

[0049] The above calculation process can be expressed as follows: TS=min (water temperature, refrigerant temperature corresponding to average refrigerant system pressure - ΔT) When the speed is greater than R2 and the duration is greater than t2, the external temperature of the vehicle can be determined based on the engine water temperature, the motor water temperature, the refrigerant system high pressure, the compensation value corresponding to the vehicle speed, the compensation value corresponding to the refrigerant system low pressure and the compensation value corresponding to the component status of the components.

[0050] In some embodiments, determining the external temperature of the vehicle according to the engine water temperature, the motor water temperature, the high pressure of the refrigerant system, the compensation value corresponding to the vehicle speed, the compensation value corresponding to the low pressure of the refrigerant system, and the compensation value corresponding to the component state of the component may include: determining a second candidate temperature according to the refrigerant temperature corresponding to the high pressure of the refrigerant system, the compensation value corresponding to the vehicle speed, and the compensation value corresponding to the component state of the component; The minimum value among the engine water temperature, the motor water temperature and the second candidate temperature is determined as the external temperature of the vehicle.

[0051] Specifically, the second candidate temperature can be determined based on the refrigerant temperature corresponding to the high pressure of the refrigerant system, the compensation value corresponding to the vehicle speed, and the compensation value corresponding to the component status of the component, that is, the saturated refrigerant temperature corresponding to the high pressure + vehicle speed compensation + fan compensation + speed compensation + low pressure compensation, and the compensation value is obtained by pre-statistical analysis. Among them, the compensation value corresponding to the component status of the component may include the compensation values ​​corresponding to the compressor status, the cooling fan status, and the battery cooling status, respectively. Then, the minimum value can be screened out from the saturated refrigerant temperature corresponding to the water temperature high pressure + vehicle speed compensation + fan compensation + speed compensation + low pressure compensation and determined as the external temperature of the vehicle.

[0052] The above calculation process can be expressed as follows: TS=min (water temperature, saturated refrigerant temperature corresponding to high pressure + vehicle speed compensation + fan compensation + speed compensation + low pressure compensation) For example, refer to the compensation values ​​corresponding to the vehicle speed and fan compensation in Table 1, the compensation values ​​corresponding to the compressor speed compensation in Table 2, and the compensation values ​​corresponding to the low pressure compensation in Table 3: Table 1:

[0053] Table 2:

[0054] Table 3:

[0055] It should be noted that the above compensation is only used as an example, and in actual applications, adaptive adjustments can be made according to actual conditions or requirements, and the embodiments of the present invention do not need to be limited to this.

[0056] In the above embodiment, the external temperature of the vehicle can be simulated based on the rotational speed, duration, first rotational speed threshold, second rotational speed threshold, first duration threshold, second duration threshold, sensor data and component status, so as to simulate and obtain the accurate external temperature.

[0057] In one embodiment of the present invention, after simulating the external temperature of the vehicle according to the sensor data and the component status, the method further comprises: When the external temperature is different from the memorized external temperature, the external temperature is displayed according to a preset output limit to simulate a change trend of the actual external temperature of the vehicle.

[0058] In an embodiment of the present invention, when the external temperature is different from the memorized external temperature, it is necessary to display the external temperature on the vehicle terminal according to the preset output limit to simulate the actual external temperature change trend of the vehicle. Exemplarily, the preset output limit may be 0.1°C / s (degrees Celsius / second). Assuming that the external temperature currently displayed on the vehicle terminal is 20.5°C and the external temperature currently simulated is 24°C, the external temperature may be displayed in sequence on the vehicle terminal as 20.6°C, 20.7°C, 20.8°C... per second.

[0059] In the above embodiment, when the simulated external temperature changes, the external temperature can be displayed on the vehicle terminal according to the preset output limit to simulate the actual external temperature change trend of the vehicle, which is consistent with the actual measurement characteristics of the temperature sensor outside the vehicle.

[0060] In one embodiment of the present invention, after simulating the external temperature of the vehicle according to the sensor data and the component status, the method further comprises: When the sensor includes a temperature sensor installed outside the vehicle, obtaining a measured external temperature corresponding to the temperature sensor; determining a target external temperature based on the measured external temperature and the external temperature; The target external temperature is displayed.

[0061] In a specific implementation, a temperature sensor may be installed on the outside of the vehicle, and the measured external temperature of the vehicle may be obtained based on the temperature sensor outside the vehicle. However, since most of the external sensors are installed near the vehicle's air intake grille or near the left and right rearview mirrors of the vehicle, and are installed at these locations, there is a possibility that the collected external temperature may be inaccurate due to the influence of light or the heat radiation from the condenser or radiator. Therefore, the embodiment of the present invention can obtain the measured external temperature of the vehicle by measuring the temperature sensor outside the vehicle, and at the same time, jointly simulate the external temperature of the vehicle according to the sensor data of the vehicle and the status of the components of the vehicle. Then, the target external temperature can be determined by combining the measured external temperature and the external temperature. For example, the average value of the measured external temperature and the external temperature can be taken as the target external temperature, which can be displayed to the driver on the vehicle terminal, or the vehicle environment of the vehicle can be controlled based on the target external temperature.

[0062] In the above embodiment, the measured external temperature collected by the temperature sensor outside the vehicle and the external temperature of the vehicle simulated based on the vehicle's sensor data and the status of the vehicle's components can be combined to jointly determine the target external temperature for display, thereby ensuring the accuracy of the external temperature displayed to the driver.

[0063] In order to enable those skilled in the art to better understand the embodiments of the present invention, specific examples are used for illustration below.

[0064] Reference Figure 2 , is a schematic diagram of the principle of vehicle external temperature simulation disclosed in the present invention; Among them, TO represents the memorized external temperature; TN=min (water temperature, refrigerant temperature corresponding to the high pressure of the refrigerant system, refrigerant temperature corresponding to the low pressure of the refrigerant system, and refrigerant system temperature); TS* represents the processing logic corresponding to the temperature range determined by the difference between TO and TN. Different temperature ranges correspond to different processing logics; TS represents the simulated value of the external temperature sensor (i.e., the simulated external temperature).

[0065] After the vehicle system wakes up, the memorized external temperature TO is obtained; according to the current water temperature, the high pressure of the refrigerant system has the corresponding refrigerant temperature, the low pressure of the refrigerant system has the corresponding refrigerant temperature, and the minimum value of the refrigerant system temperature is taken as TN; by comparing the difference between TO and TN with the value of the temperature range interval, the processing logic of TS corresponding to the temperature range interval in which the difference falls is obtained, that is, TS* is obtained; the final output value TS can be obtained according to TS*. Among them, the temperature range interval of TS* can be made into multiple temperature range intervals according to different vehicle models or different needs, for example, there can be temperature range intervals such as TS1, TS2, and TS3.

[0066] Reference Figure 3 , is a schematic diagram of an external temperature simulation based on different temperature ranges disclosed in the present invention, in which each TS* has different R1 (first speed threshold) and R2 (second speed threshold) as well as t1 (first duration threshold) and t2 (second duration threshold).

[0067] Get the current compressor speed and duration. When the speed is less than R1, or greater than R2, enter different processing logics of TS by comparing the difference between the current compressor speed and R1 or R2, and the difference between the duration of the speed and t1 or t2. It should be added that when the speed is greater than or equal to R1, and the speed is less than or equal to R2, that is, when R1≤speed≤R2, no processing is required. Specifically: When the rotation speed is less than R1 and the duration is less than t1, and when the rotation speed is greater than R2 and the duration is less than t2, TS=TN.

[0068] When the speed is less than R1 and the duration is greater than t1, the vehicle's external temperature can be calculated based on the engine water temperature, motor water temperature, refrigerant system high pressure, refrigerant system low pressure and the preset offset value, that is: TS=min (water temperature, refrigerant temperature corresponding to the average refrigerant system pressure - ΔT).

[0069] When the speed is greater than R2 and the duration is greater than t2, the vehicle's external temperature can be calculated based on the engine water temperature, motor water temperature, refrigerant system high pressure, compensation value corresponding to vehicle speed, compensation value corresponding to refrigerant system low pressure and compensation value corresponding to component status, that is: TS=min (water temperature, refrigerant temperature corresponding to high pressure + vehicle speed compensation + fan compensation + speed compensation + low pressure compensation).

In actual use, the external temperature in various scenarios can be jointly simulated through the status of the above sensors and components. Each sensor and component status will compensate for the simulated external temperature, so that it changes from a single sensor to a coupled calculation of each sensor, which is relatively more accurate and more representative of the actual external temperature.
