[0002] With the continuous development of the automotive industry, the external temperature display function of vehicles has become a standard configuration of automobiles.

Moreover, the vehicle controller can perform adaptive adjustments on the vehicle based on the external temperature, thereby providing a more comfortable vehicle environment for the driver. Although some manufacturers are equipped with temperature sensors outside the vehicle to collect the external temperature according to the temperature sensors, since most of the external sensors are installed near the intake grille of the vehicle or near the left and right rearview mirrors of the vehicle, the external temperature collected may be inaccurate due to the influence of light or the heat radiation of the condenser or radiator at these installation positions.

[0063] 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 content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed 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, rather than for limiting the protection scope of the present invention.

[0064] Refer to Figure 1 , which shows the step flowchart of a method for simulating the external temperature of a vehicle provided in an embodiment of the present invention. The vehicle is configured with at least one sensor and components, and specifically includes the following steps:

[0065] Step 101, obtain the sensor data collected by the sensor and the component status of the component; the sensor data is used to determine the temperature of at least one sensor of the vehicle.

[0066] In practical applications, a vehicle is usually configured with at least one sensor and components, usually multiple. Exemplarily, the sensors can include temperature sensors, pressure sensors, speed sensors, etc., and the components can include cooling fans, compressors, and batteries, etc.

[0067] In an embodiment of the present invention, sensor data collected by sensors on a vehicle can be obtained. Exemplarily, the sensor data may at least include data such as engine coolant temperature, motor coolant temperature, high-pressure pressure of the refrigerant system, low-pressure pressure of the refrigerant system, refrigerant system temperature, and vehicle speed. Among them, the refrigerant system is a refrigeration cycle system in vehicle thermal management, and its core components may include a compressor, a condenser, an expansion valve, an evaporator, etc. By utilizing the phase change characteristics of the refrigerant, heat in the passenger compartment or the battery is absorbed to achieve temperature control. The high-pressure pressure of the refrigerant system is the high-pressure side pressure of the refrigerant from the compressor outlet to before the expansion valve, which reflects the heat dissipation efficiency of the condenser. 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, which reflects 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. The refrigerant system temperature is the temperature of the low-temperature and low-pressure gaseous refrigerant collected by a temperature sensor installed on the low-pressure side of the refrigeration cycle (usually at the evaporator outlet or the compressor suction pipeline). For the sake of convenience in description, hereinafter, the engine coolant temperature, motor coolant temperature, refrigerant system temperature, the high-pressure pressure of the refrigerant system having a corresponding refrigerant temperature, and the low-pressure pressure of the refrigerant system having a corresponding refrigerant temperature are collectively referred to as sensor temperature.

[0068] In an embodiment of the present invention, the component states corresponding to components on the vehicle can also be obtained. The component states may at least include compressor state, cooling fan state, and battery cooling state. Among them, the compressor state may at least include the rotational speed of the compressor; the cooling fan state at least includes the rotational speed of the cooling fan; the battery cooling state at least includes battery cooling strategy on and battery cooling strategy off. Specifically, when the battery cooling strategy is on, components such as an electric water pump and a cooling fan on the vehicle can be started to perform thermal management on the battery.

[0069] Step 102: Obtain the memory external temperature of the vehicle obtained from the previous simulation.

[0070] Step 103: Obtain at least one temperature range interval of the vehicle; the temperature range interval has a corresponding processing logic.

[0071] Step 104: Take the minimum value in the sensor temperature as the target temperature.

[0072] Step 105: Take the temperature range interval into which the difference between the memory external temperature and the target temperature falls as the target temperature range interval.

[0073] Step 106: Simulate the external temperature of the vehicle according to the processing logic corresponding to the target temperature range interval, the sensor data, and the component states.

[0074] In an embodiment of the present invention, after obtaining sensor data and component status, the external temperature of the vehicle can be simulated by combining these data, and then the simulated external temperature can be displayed on the in-vehicle terminal of the vehicle, or the vehicle can be controlled based on the external temperature. For example, when the external temperature of the vehicle is too high, the rotation speed of the compressor of the vehicle's air-conditioning system or the rotation speed of the cooling fan can be increased, etc.

[0075] In some cases, some vehicles do not install a temperature sensor outside the vehicle to measure the external temperature due to cost and other factors, or when the temperature sensor installed outside the vehicle fails, the external temperature of the vehicle can be simulated by combining sensor data and component status. Since the vehicle in the embodiment of the present invention does not need to separately set a temperature sensor outside the vehicle, the manufacturing cost of the whole vehicle can be reduced and it will not be affected by the arrangement position of the temperature sensor outside the vehicle, the heat radiation of the radiator, etc., ensuring the accuracy of the obtained external temperature.

[0076] In an embodiment of the present invention, the external temperature of the vehicle simulated last time can be obtained as the memory external temperature, and the external temperature of the vehicle can be jointly simulated according to the memory external temperature, sensor data and component status.

[0077] In some embodiments, when there is no memory external temperature of the vehicle simulated last time, for example, when initially starting to simulate the external temperature of the vehicle, the minimum value among the sensor temperatures can be used as the memory external temperature. That is, from the engine water temperature, the motor water temperature, the refrigerant system temperature, the refrigerant system high-pressure pressure with the corresponding refrigerant temperature, and the refrigerant system low-pressure pressure with the corresponding refrigerant temperature, the minimum value is selected as the memory external temperature for jointly simulating the external temperature of the vehicle with the sensor data and component status. In the above embodiment, the external temperature of the vehicle can be jointly simulated according to the memory external temperature, sensor data and component status, so as to simulate an accurate external temperature.

[0078] In specific implementation, at least one temperature range interval is preset for the vehicle, and each temperature range interval has a corresponding processing logic, where the processing logic may include a rotation speed threshold and a duration threshold. It should be noted that the temperature range intervals can be made in multiple numbers or different numerical temperature range intervals according to different vehicle models or different requirements. For example, there can be three temperature range intervals TS1, TS2, and TS3. The embodiments of the present invention do not need to be limited thereto.

[0079] In an embodiment of the present invention, the minimum value among the sensor temperatures can be used as the memory external temperature. That is, from the engine water temperature, the motor water temperature, the refrigerant system temperature, the refrigerant temperature corresponding to the high pressure of the refrigerant system, and the refrigerant temperature corresponding to the low pressure of the refrigerant system, the minimum value is selected as the target temperature. Then, the temperature range interval into which the difference between the memory external temperature and the target temperature falls is determined. Next, the external temperature of the vehicle can be jointly simulated according to the processing logic corresponding to the target temperature range interval, the sensor data, and the component status.

[0080] In the above embodiment, the external temperature of the vehicle can be jointly simulated according to the processing logic corresponding to the target temperature range interval, the sensor data, and the component status, so as to simulate an accurate external temperature.

[0081] In the above vehicle external temperature simulation method, the vehicle is equipped with at least one sensor and components. The sensor data collected by the sensor and the component status of the components are obtained. Among them, at least one sensor temperature of the vehicle can be determined according to the sensor data. Then, the memory external temperature of the vehicle obtained by the previous 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 among the sensor temperatures is used as the target temperature. Then, the temperature range interval into which the difference between the memory external temperature and the target temperature falls is used as the target temperature range interval. Furthermore, the external temperature of the vehicle can be simulated according to the processing logic corresponding to the target temperature range interval, the sensor data, and the component status. In the embodiment of the present invention, when the vehicle is not equipped with a temperature sensor or the external temperature collected by the temperature sensor is inaccurate, etc., the sensor data collected by the sensors already equipped on the vehicle and the component status of the components can be used to jointly simulate an accurate external temperature of the vehicle. Without increasing the hardware cost of the vehicle, an accurate external temperature can be obtained, so that a better vehicle environment can be provided for the driver of the vehicle based on the accurate external temperature.

[0082] In an embodiment of the present invention, simulating the external temperature of the vehicle according to the processing logic corresponding to the target temperature range interval, the sensor data, and the component status includes:

[0083] Obtain the rotation speed and duration of the compressor of the vehicle;

[0084] Obtain the rotation speed threshold and duration threshold in the processing logic corresponding to the target temperature range interval;

[0085] Simulate the external temperature of the vehicle according to the rotation speed, the duration, the rotation speed threshold, the duration threshold, the sensor data, and the component status.

[0086] Among them, the processing logic may include a rotational speed threshold and a duration threshold.

[0087] In an embodiment of the present invention, after obtaining the processing logic corresponding to the target temperature range interval, the rotational speed and duration of the vehicle's current compressor can be obtained, and then the external temperature of the vehicle can be simulated based on the rotational speed, duration, rotational speed threshold, duration threshold, sensor data, and component status.

[0088] In the above embodiment, the external temperature of the vehicle can be jointly simulated based on the rotational speed, duration, rotational speed threshold, duration threshold, sensor data, and component status, so as to simulate an accurate external temperature.

[0089] In an 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 status includes:

[0090] When the rotational speed is less than the first rotational speed threshold and the duration is less than the first duration threshold, and when the rotational speed is greater than the second rotational speed threshold and the duration is less than the second duration threshold, the target temperature is determined as the external temperature of the vehicle;

[0091] When the rotational speed is less than the first rotational speed threshold and the duration is greater than the first duration threshold, the external temperature of the vehicle is determined according to the engine water temperature, the motor water temperature, the high-pressure pressure of the refrigerant system, the low-pressure pressure of the refrigerant system, and a preset offset value;

[0092] When the rotational speed is greater than the second rotational speed threshold and the duration is greater than the second duration threshold, the external temperature of the vehicle is determined according to the engine water temperature, the motor water temperature, the high-pressure pressure of the refrigerant system, the compensation value corresponding to the vehicle speed, the compensation value corresponding to the low-pressure pressure of the refrigerant system, and the compensation value corresponding to the component status of the component.

[0093] Among them, the rotational speed threshold may include a first rotational speed threshold R1 and a second rotational 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 in the sensor temperature.

[0094] When the rotational speed is less than R1 and the duration is less than t1, and when the rotational speed is greater than R2 and the duration is less than t2, the target temperature can be determined as the external temperature of the vehicle, that is, TS = TN.

[0095] When the rotational 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 high-pressure pressure of the refrigerant system, the low-pressure pressure of the refrigerant system, and a preset offset value.

[0096] In some embodiments, determining the external temperature of the vehicle based on the engine water temperature, the motor water temperature, the high-pressure pressure of the refrigerant system, the low-pressure pressure of the refrigerant system, and a preset offset value includes:

[0097] Performing an averaging process on the high-pressure pressure of the refrigerant system and the low-pressure pressure of the refrigerant system to obtain an average refrigerant system pressure;

[0098] Determining a first candidate temperature based on the refrigerant temperature corresponding to the average refrigerant system pressure and the preset offset value;

[0099] Determining the minimum value among the engine water temperature, the motor water temperature, and the first candidate temperature as the external temperature of the vehicle.

[0100] Wherein, ΔT represents the preset offset value.

[0101] In a specific implementation, by statistically analyzing the pressures and refrigerant temperatures of a large number of vehicles, the refrigerant temperatures corresponding to different pressures can be determined. In a specific embodiment, the calculation formula for the refrigerant temperature can be:

[0102] 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.

[0103] Wherein, the pressure unit is kilopascal kPa and the temperature unit is degree Celsius °C.

[0104] In this way, after determining the pressure, the refrigerant temperature corresponding to the pressure can be determined based on the above calculation formula for the refrigerant temperature.

[0105] 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, statistical analysis can be performed on the external temperatures obtained from multiple simulations and the actual external temperature to obtain the preset offset value. Thus, 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, by analyzing the external temperatures obtained from simulations and the actual external temperature under different vehicle speeds, low-side pressures of the refrigerant system, and component states of components, the corresponding compensation values under different vehicle speeds, low-side pressures of the refrigerant system, and component states of components can be determined. Among them, the corresponding compensation values under different vehicle speeds, low-side pressures of the refrigerant system, and component states of components can be stored in the form of a table. Thus, when simulating the external temperature, the compensation value corresponding to the current vehicle speed, low-side pressure of the refrigerant system, and component state of components can be obtained by looking up the table, and then the simulated external temperature can be compensated based on the compensation value, thereby improving the accuracy of the simulated external temperature.

[0106] In an embodiment of the present invention, an average refrigerant system pressure is obtained by averaging the high-side pressure and the low-side pressure of the refrigerant system, that is, the average refrigerant system pressure is obtained by summing the high-side pressure of the refrigerant system + the low-side pressure of the refrigerant system and then dividing by 2. Then, the refrigerant temperature corresponding to the average refrigerant system pressure can be obtained. Combining this refrigerant temperature and ΔT, a first candidate temperature is obtained, that is, the refrigerant temperature corresponding to the average refrigerant system pressure - ΔT. Then, the minimum value can be selected from the water temperature (engine water temperature and motor water temperature) and the refrigerant temperature corresponding to the average refrigerant system pressure - ΔT and determined as the external temperature of the vehicle.

[0107] The above calculation process can be expressed by the formula as:

[0108] TS = min(water temperature, refrigerant temperature corresponding to the average refrigerant system pressure - ΔT)

[0109] When the rotational 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, motor water temperature, high-side pressure of the refrigerant system, compensation value corresponding to the vehicle speed, compensation value corresponding to the low-side pressure of the refrigerant system, and compensation value corresponding to the component state of components.

[0110] In some embodiments, determining the external temperature of the vehicle based on the engine water temperature, the motor water temperature, the high-side pressure of the refrigerant system, the compensation value corresponding to the vehicle speed, the compensation value corresponding to the low-side pressure of the refrigerant system, and the compensation value corresponding to the component state of components may include:

[0111] Determine a second candidate temperature 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 state of the component;

[0112] Determine the minimum value among the engine coolant temperature, the motor coolant temperature, and the second candidate temperature as the external temperature of the vehicle.

[0113] Specifically, the second candidate temperature can be determined 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, 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 through pre-statistical analysis. Among them, the compensation value corresponding to the component state of the component can include the compensation values corresponding to the compressor state, the cooling fan state, and the battery cooling state respectively. Then, the minimum value can be selected from the saturated refrigerant temperature corresponding to the coolant high-pressure + vehicle speed compensation + fan compensation + speed compensation + low-pressure compensation and determined as the external temperature of the vehicle.

[0114] The above calculation process can be expressed by the formula:

[0115] TS = min (coolant temperature, saturated refrigerant temperature corresponding to high-pressure + vehicle speed compensation + fan compensation + speed compensation + low-pressure compensation)

[0116] Exemplarily, refer to the compensation values corresponding to the vehicle speed and fan compensation in Table 1 below, 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:

[0122]

[0123] It should be noted that the above compensation is only an example, and in actual applications, it can be adjusted adaptively according to actual situations or requirements, and the embodiments of the present invention do not need to be limited thereto.

[0124] In the above embodiment, the external temperature of the vehicle can be jointly simulated according to the speed, duration, first speed threshold, second speed threshold, first duration threshold, second duration threshold, sensor data, and component state, so as to simulate and obtain an accurate external temperature.

[0125] In an embodiment of the present invention, after simulating the external temperature of the vehicle based on the sensor data and the component status, the method further includes:

[0126] When the external temperature is different from the memorized external temperature, display the external temperature according to a preset output limit to simulate the real external temperature change trend of the vehicle.

[0127] 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 in-vehicle terminal according to a preset output limit to simulate the real external temperature change trend of the vehicle. Exemplarily, the preset output limit can be 0.1 °C / s (degrees Celsius per second). Suppose the external temperature currently displayed on the in-vehicle terminal is 20.5 °C and the currently simulated external temperature is 24 °C, then on the in-vehicle terminal, it can be displayed successively as 20.6 °C, 20.7 °C, 20.8 °C... per second.

[0128] In the above embodiment, when the simulated external temperature changes, the external temperature can be displayed on the in-vehicle terminal according to a preset output limit to simulate the real external temperature change trend of the vehicle, which conforms to the measurement characteristics of the temperature sensor outside the vehicle in reality.

[0129] In an embodiment of the present invention, after simulating the external temperature of the vehicle based on the sensor data and the component status, the method further includes:

[0130] When the sensor includes a temperature sensor installed outside the vehicle, obtain the measured external temperature corresponding to the temperature sensor;

[0131] Determine the target external temperature according to the measured external temperature and the external temperature;

[0132] Display the target external temperature.

[0133] In specific implementation, a temperature sensor can be installed outside the vehicle, and the measured external temperature of the vehicle can be obtained based on the temperature sensor outside the vehicle. However, since most of the external sensors are installed near the intake grille of the vehicle or near the left and right rearview mirrors of the vehicle, and installing in these positions will be affected by light or the heat radiation of the condenser or radiator, resulting in inaccurate external temperature collection. Therefore, in an embodiment of the present invention, while obtaining the measured external temperature of the vehicle measured by the temperature sensor outside the vehicle, the external temperature of the vehicle can be jointly simulated according to the sensor data of the vehicle and the component status of the vehicle, and 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 and displayed to the driver on the in-vehicle terminal, or the vehicle environment of the vehicle can be controlled based on the target external temperature.

[0134] In the above embodiments, the measured external temperature collected by the external temperature sensor of the vehicle can be combined with the external temperature of the vehicle jointly simulated based on the sensor data of the vehicle and the component states of the vehicle to jointly determine the target external temperature to be displayed, ensuring the accuracy of the external temperature displayed to the driver.

[0135] To enable those skilled in the art to better understand the embodiments of the present invention, specific examples are used for illustration below.

[0136] Refer to Figure 2 , which is a schematic diagram of the principle of simulating the external temperature of a vehicle disclosed by the present invention;

[0137] Among them, TO represents the memorized external temperature; TN = min (water temperature, refrigerant temperature corresponding to the high-pressure pressure of the refrigerant system, refrigerant temperature corresponding to the low-pressure pressure of the refrigerant system, refrigerant system temperature); TS* represents the processing logic corresponding to the temperature range interval determined according to the difference between TO and TN, and different temperature range intervals correspond to different processing logics; TS represents the analog value of the external temperature sensor (i.e., the analog external temperature).

[0138] After the vehicle system is awakened, the memorized external temperature TO is obtained; the minimum value of the current water temperature, the refrigerant temperature corresponding to the high-pressure pressure of the refrigerant system, the refrigerant temperature corresponding to the low-pressure pressure of the refrigerant system, and the refrigerant system temperature is taken as TN; by comparing the difference between TO and TN with the values in the temperature range interval, the processing logic of TS corresponding to the temperature range interval into which the difference falls is obtained, that is, TS* is obtained; the final output value TS can be obtained according to TS*. The temperature range intervals of TS* can be made into multiple temperature range intervals respectively according to different vehicle models or different requirements. For example, there can be temperature range intervals such as TS1, TS2, and TS3.

[0139] Refer to Figure 3 , which is a schematic diagram of simulating the external temperature based on different temperature range intervals disclosed by the present invention. Different R1 (first rotational speed threshold) and R2 (second rotational speed threshold) as well as t1 (first duration threshold) and t2 (second duration threshold) exist in each TS*.

[0140] The current rotational speed and duration of the compressor are obtained. When the rotational speed is less than R1, or the rotational speed is greater than R2, by comparing the difference between the current rotational speed of the compressor and R1 or R2, and the difference between the duration of the rotational speed and t1 or t2, different processing logics of TS are entered. It should be added that when the rotational speed is greater than or equal to R1 and less than or equal to R2, that is, when R1 ≤ rotational speed ≤ R2, no processing is required. Specifically:

[0141] 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.

[0142] 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).

[0143] 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).

[0144] In summary, the purpose of the present invention is to provide a method for simulating the collected values of an external temperature sensor, which simulates the collected values of the external temperature sensor (simulated external temperature) through the sensor data of other sensors of the vehicle and the component status of the execution components (parts), including the engine water temperature, motor water temperature, refrigerant system high pressure, refrigerant system low pressure, refrigerant system temperature, vehicle speed and compressor status, cooling fan status, battery cooling status, etc. to jointly simulate the external temperature. 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.

[0145] The embodiments of the present invention have at least the following advantages: The embodiments of the present invention are based on the joint simulation of external temperature by multiple sensors and have a high degree of fault tolerance. The vehicle does not need to be equipped with a separate temperature sensor outside the vehicle, which can reduce the manufacturing cost of the entire vehicle and will not be affected by the layout position of the temperature sensor, the heat radiation of the radiator, etc. The measured external temperature collected by the temperature sensor outside the vehicle can be compensated and calculated using the simulated external temperature, so that the obtained external temperature is more accurate. When the temperature sensor outside the vehicle fails, it can be used as a substitute for the temperature sensor outside the vehicle to obtain the external temperature.
