The development of thermal management systems has also been greatly affected. At present, intelligent control and intelligent air-conditioning application scenarios and functions are popularized in many vehicle configurations, but the realization of these scene functions requires automatic air-conditioning configuration, and the accurate collection and filtering judgment of ambient temperature in automatic air-conditioning configuration belongs to the core algorithm of each OEM or technology supplier.

[0004] Currently, there are two main design directions for vehicle-displayed ambient temperature. One is simulation calculation, which mainly relies on collected information such as in-vehicle temperature, evaporator temperature, engine coolant temperature, vehicle speed signal, sunlight intensity, etc., and calculates the real-time ambient temperature through a relatively complex model algorithm and combines it with actual vehicle calibration and verification work to complete the application; the other is to use outdoor temperature sensor hardware collection, combined with software filtering algorithm and actual vehicle calibration, verification work after completion to carry out the application; the latter is more widely used, but some real vehicle scenarios cannot be fully covered, resulting in the inability of automatic air conditioning to realize full-scene functions.

[0039] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0040] It should be noted that the terms used herein are for describing specific embodiments only and are not intended to be limiting of exemplary embodiments according to the present invention.

[0041] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0042] Before explaining in detail the vehicle heater control method provided in the embodiment of the present application, the application scenarios and implementation environment involved in the embodiment of the present application are first introduced.

[0043] For the current vehicle ambient temperature collection and display, whether it is a simulation calculation method or a hardware collection method relying on an outdoor temperature sensor, it is difficult to distinguish between the collection and calculation temperature increase caused by the engine heat reflux and the increase in the actual vehicle's ambient temperature. In particular, there is no effective way to filter the impact of the engine heat reflux on the external temperature collection during the vehicle idling phase. Because it is impossible to distinguish between the increase in the actual external temperature and the increase in the collection value caused by the engine heat reflux, the software strategy either filters out both scenarios or collects both. However, either method will cause the problem of external temperature distortion.

[0044] Based on this, the present application provides a vehicle ambient temperature display and confirmation method, which can effectively cover the external environment of the vehicle under different usage environments such as seasonal changes, vehicle speed changes, road environment changes, warehousing and outbound scenarios, exposure scenarios, and vehicle immersion scenarios, thereby realizing real-time and accurate display of the vehicle ambient temperature; and it can also effectively avoid the impact of engine heat reflux.

[0045] The results of an implementation environment of this embodiment are described. The implementation environment includes an outdoor temperature sensor, an electronic control unit, a display module, an evaporator temperature sensor, and an engine temperature sensor.

[0046] like Figure 3 As shown, the outdoor temperature sensor can use a T-type NTC, i.e., a T-type negative temperature coefficient thermistor acquisition circuit. Because it is generally powered by 5V, it is matched with a pull-up resistor and a filter circuit and then connected to the acquisition circuit to complete the hardware interface design. The outdoor temperature sensor is generally installed at the opening of the front grille of the vehicle, close to the radiator, and is used to measure the ambient temperature. The resistance of the outdoor temperature sensor changes with the ambient temperature. The hardware acquisition circuit of the MCU collects different voltages and converts them into resistances, and then the actual temperature currently collected can be calculated by looking up the table. The evaporator temperature sensor is installed on the evaporator, close to the wiper position, and is used to measure the evaporator temperature. The engine temperature sensor is generally installed on the water jacket of the engine cylinder block or cylinder head to measure the engine water temperature. The electronic control unit is used to receive the values ​​measured by the outdoor ambient temperature sensor, the evaporator temperature sensor, and the engine temperature sensor, and perform a series of processing calculations to obtain the vehicle ambient temperature displayed on the display module.

[0047] It should be noted that the application scenarios and implementation environments described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the emergence of new application scenarios and the evolution of the implementation environment, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0048] Next, a vehicle ambient temperature display confirmation method provided by this embodiment is explained in detail.

[0049] Figure 1 A flow chart of a vehicle ambient temperature display confirmation method provided in this embodiment, the method comprising:

[0050] Step 101: Determine that the current vehicle external temperature is in a rising stage;

[0051] Step 1011: when the engine water temperature is greater than the first temperature threshold, if the current vehicle speed is less than the first vehicle speed threshold, and the compressor in the vehicle air conditioning system is not in operation, the collected evaporator temperature is used as the ambient temperature displayed by the vehicle;

[0052] Step 1012: when the engine water temperature is not greater than the first temperature threshold and the vehicle KL15 is not powered on, if the current vehicle speed is not less than the second vehicle speed threshold, the ambient temperature displayed by the vehicle is updated according to the difference between the actual vehicle external temperature and the calculated vehicle external temperature;

[0053] Step 1013: If the vehicle speed is less than the second vehicle speed threshold and the compressor in the vehicle air conditioning system is not in operation, the collected evaporator temperature is used as the ambient temperature displayed by the vehicle; wherein the first vehicle speed threshold is greater than the second vehicle speed threshold;

[0054] Step 102: Confirm that the current vehicle external temperature is in a decreasing stage, and then update the ambient temperature displayed by the vehicle according to the difference between the actual vehicle external temperature and the calculated vehicle external temperature.

[0055] In the present application, the judgment of whether the current vehicle external temperature is in the rising stage or the falling stage is specifically as follows: calculating the difference between the real-time collected value of the vehicle external temperature and the ambient temperature value stored in the vehicle;

[0056] If the calculated difference is greater than zero, the current vehicle external temperature is in the rising stage;

[0057] If the calculated difference is less than zero, the current vehicle external temperature is in a decreasing stage.

[0058] In the present application, under the condition that the vehicle power supply is valid, the comparison between the vehicle collected outside temperature and the vehicle displayed outside temperature is first completed, that is, the difference between the temperature value collected in real time by the outdoor temperature sensor and the ambient temperature value stored in the EEP is calculated. If the calculated difference is greater than zero, it is determined that the current vehicle collected temperature, that is, the vehicle outside temperature, is in an increasing range. If the difference is less than zero, it is determined that the current vehicle collected temperature, that is, the vehicle outside temperature, is in a decreasing range.

[0059] In step 1011 of the present application, when the temperature outside the vehicle is in a rising stage, the engine water temperature is greater than the first temperature threshold, the current vehicle speed is less than the first vehicle speed threshold, and the compressor in the vehicle's air-conditioning system is in an inoperative state, the matched scenario is that the vehicle is warmed up in winter and slowly drives into a warm storage at a low speed. At this time, because the engine heat reflux has strong thermal radiation to the outdoor temperature sensor, and there is no fresh air flow at the location where the outdoor temperature sensor is arranged, the airflow flowing into the fresh air circulation of the air conditioner can effectively pass through the evaporator core, so the temperature collection value of the evaporator temperature sensor can effectively replace the collection value of the outdoor temperature sensor, thereby completing the calculation and display of the vehicle ambient temperature.

[0060] For example, when the engine water temperature is greater than 50°C, if the current vehicle speed is less than 30 kilometers per hour, and the compressor in the vehicle's air-conditioning system is not working, the collected evaporator temperature will be used as the ambient temperature displayed by the vehicle.

[0061] In step 1012 of the present application, specifically: when the engine water temperature is not greater than the first temperature threshold and there is no power-on action for the vehicle KL15, if the current vehicle speed is not less than the first vehicle speed threshold, then based on a first ratio of the actual vehicle external temperature to the calculated vehicle external temperature difference, the current vehicle ambient temperature calculation value is updated at a first set interval, thereby updating the ambient temperature displayed by the vehicle.

[0062] Specifically, vehicle KL15 may specifically refer to the air-conditioning working power supply. When the engine water temperature is not greater than the first temperature threshold, and there is no power-on action in vehicle KL15, and the current vehicle speed is not less than the first vehicle speed threshold, the corresponding scenario is matched as the vehicle continues to drive after idling. By updating the current vehicle ambient temperature calculation value at a first set interval based on a first ratio of the actual vehicle external temperature and the calculated vehicle external temperature difference, and then updating the ambient temperature displayed by the vehicle, the influence of heat reflux around the outdoor temperature sensor during idling can be effectively filtered out.

[0063] It should be noted that the first ratio and the first set interval may be set accordingly according to actual vehicle conditions, and this embodiment does not specifically limit the specific values ​​of the first ratio and the first set interval.

[0064] For example, when the vehicle is in the stage of rising outside temperature, the engine water temperature is less than or equal to 50°C, the KL15 power supply remains unchanged, and the vehicle speed is greater than or equal to 30 kilometers per hour, the ambient temperature display and calculated value are updated every 60 seconds according to the value collected by the outdoor temperature sensor, but each update is one-sixth of the difference between the actual outside temperature and the outside temperature in the algorithm, that is, the actual outside temperature is added to the current ambient temperature display value. One-sixth of the difference between the outside temperature in the algorithm; the outside temperature in the algorithm refers to the difference calculation process value, and the first outside temperature in the algorithm is the effective value of the ambient temperature in the previous frame; the corresponding scenario is that the vehicle continues to drive after idling, and the outside temperature is updated once a minute, with one-sixth of the difference updated each time, effectively filtering out the heat reflux effect around the outdoor temperature sensor during idling.

[0065] When the engine water temperature is not greater than the first temperature threshold and the vehicle KL15 does not have a power-on action, if the current vehicle speed is less than the first vehicle speed threshold and not less than the second vehicle speed threshold, the current vehicle ambient temperature calculation value is updated at a second set interval based on a second ratio of the actual vehicle external temperature to the calculated vehicle external temperature difference, and then the ambient temperature displayed by the vehicle is updated; wherein the first set interval is greater than the second set interval, and the first ratio is less than the second ratio.

[0066] Specifically, when the engine water temperature is not greater than the first temperature threshold and there is no power-on action on the vehicle KL15, and the current vehicle speed is less than the first vehicle speed threshold and not less than the second vehicle speed threshold, the matching scenario is that the vehicle continues to drive slowly at a low speed after idling, and the outside temperature is updated according to the second set interval, effectively filtering out the heat reflux effect around the outdoor temperature sensor during idling and increasing the update frequency.

[0067] For example, when the vehicle is in the stage of external temperature rising, the engine water temperature is less than or equal to 50°C, the KL15 power supply does not change during the process, and the vehicle speed is less than 30 kilometers per hour and greater than or equal to 5 kilometers per hour, the ambient temperature display and calculated value are updated every 30 seconds according to the value collected by the outdoor temperature sensor, but each update is half of the difference between the actual external temperature and the external temperature in the algorithm, that is, the actual external temperature is added to the current ambient temperature display value. Half of the difference between the external temperature in the algorithm is added; the external temperature in the algorithm refers to the difference calculation process value, and the external temperature in the algorithm for the first time is the effective value of the ambient temperature in the previous frame; the corresponding scenario is that the vehicle continues to drive slowly at a low speed after idling, and the external temperature is updated every half a minute, which effectively filters the heat reflux around the outdoor temperature sensor during idling and increases the update frequency.

[0068] In step 1013, specifically: when the vehicle's outdoor temperature is in the rising stage, the engine water temperature is not greater than the first temperature threshold, the vehicle KL15 does not have a power-on action, the current vehicle speed is less than the second vehicle speed threshold, and the compressor in the vehicle's air-conditioning system is in the off state, and the corresponding scenario is the idle-to-idle condition. At this time, because the engine heat reflux has strong heat radiation to the periphery of the outdoor temperature sensor, no fresh air flows through, but at this time the airflow flowing in from the air-conditioning fresh air circulation can effectively pass through the evaporator core, so the collection value of the evaporator temperature sensor can replace the collection value of the outdoor temperature sensor to complete the display and calculation of the ambient temperature.

[0069] For example, when the vehicle's outside temperature is in the rising stage, the engine water temperature is less than or equal to 50°C, the KL15 power supply does not change, the vehicle speed is less than 5 kilometers per hour, and the compressor is in the off state, the evaporator temperature sensor collection value is used to replace the outdoor temperature sensor collection value to complete the ambient temperature calculation and display.

[0070] The present application also includes: when the vehicle's external temperature is in the rising stage, the engine water temperature is not greater than the first temperature threshold, the vehicle KL15 does not have a power-on action, if the current vehicle speed is less than the second vehicle speed threshold, and the compressor in the vehicle's air-conditioning system is in working condition, the ambient temperature displayed by the vehicle will not be updated.

[0071] Specifically, when the vehicle's external temperature is in the rising stage, the engine water temperature is not greater than the first temperature threshold, the vehicle KL15 does not have a power-on action, the current vehicle speed is less than the second vehicle speed threshold, and the compressor in the vehicle's air-conditioning system is in working condition, then the ambient temperature is not updated, that is, the EEP storage value is used to complete the ambient temperature display and calculation; the matching corresponding scenario is idling to idling and turning on the air-conditioning condition, because the ambient temperature collected before idling is relatively real, at this time the temperature value stored in the EEP is also the effective ambient temperature of the previous frame, that is, the ambient temperature collected during driving, so this scenario filters the collection value, and it is more appropriate to use the storage value.

[0072] For example, when the vehicle's external temperature is in the rising stage, the engine water temperature is less than or equal to 50°C, the KL15 power supply does not change, and the vehicle speed is less than 5 kilometers per hour, the compressor is in working condition, and the ambient temperature is not updated at this time, that is, the EEP storage value is used to complete the ambient temperature display and calculation.

[0073] The present application also includes: when the vehicle temperature is in the rising range and the engine water temperature is greater than the first temperature threshold, if the current vehicle speed is less than the first vehicle speed threshold, and the compressor in the vehicle air conditioning system is in operation, the ambient temperature displayed by the vehicle will not be updated. At this time, the matching corresponding scene is the vehicle entering the idle condition after the hot car is driven in spring and autumn. Because the ambient temperature collected during driving is relatively real, the temperature value stored in the EEP is also the effective ambient temperature of the previous frame, that is, the ambient temperature collected during driving. Therefore, it is more appropriate to use the storage value to filter the collected value in this scene.

[0074] For example, when the vehicle temperature is in the rising range, the engine water temperature is greater than 50°C, the vehicle speed is less than 30 kilometers per hour, and the compressor is in operation, the ambient temperature is not updated, that is, the EEP storage value is used to complete the ambient temperature display and calculation.

[0075] The present application also includes: when the current vehicle external temperature is in a rising stage, the engine water temperature is greater than the first temperature threshold, and the current vehicle speed is greater than the first vehicle speed threshold, the corresponding scenario is matched as a tropical climbing condition, the engine temperature rises quickly at a high speed, but the vehicle speed is not high. At this time, a first set interval is used to update the first ratio of the actual vehicle external temperature to the calculated vehicle external temperature difference, which can effectively filter out the impact of engine heat reflux.

[0076] For example, when the actual vehicle is in the rising outside temperature range, the engine water temperature is greater than 50°C, and the vehicle speed is greater than or equal to 30 kilometers per hour, the ambient temperature display and calculated value are updated every 60 seconds according to the value collected by the outdoor temperature sensor, but each update is one-sixth of the difference between the actual outside temperature and the outside temperature in the algorithm, that is, the actual outside temperature is added to the current ambient temperature display value. One-sixth of the difference between the outside temperature in the algorithm is added; the outside temperature in the algorithm refers to the difference calculation process value, and the first outside temperature in the algorithm is the effective value of the ambient temperature in the previous frame; the corresponding scenario is a tropical climbing condition, where the engine temperature rises quickly at a high speed, but the vehicle speed is not high. At this time, it is updated once a minute and one-sixth each time, which can effectively filter out the impact of engine heat reflux.

[0077] The present application also includes: when the current vehicle external temperature is in the rising stage, the engine water temperature is not greater than the first temperature threshold, the vehicle KL15 changes from OFF to ON state, and the corresponding scene is matched with the vehicle parking outdoors. The ambient temperature update is completed after the user enters the vehicle and starts the vehicle.

[0078] For example, when the actual vehicle is in the rising range of external temperature, the engine water temperature is less than or equal to 50°C, and the KL15 power supply changes from OFF to ON, the ambient temperature is updated according to the value collected by the outdoor temperature sensor.

[0079] In step 102, specifically, when the current vehicle external temperature is in a decreasing stage, the current vehicle ambient temperature calculation value is updated according to the difference between the actual vehicle external temperature and the calculated vehicle external temperature, and then the ambient temperature displayed by the vehicle is updated, specifically:

[0080] When the current vehicle external temperature is in a decreasing stage, if the current vehicle speed is not less than the third vehicle speed threshold, the current vehicle ambient temperature calculation value is updated at a first set interval according to a third ratio of the vehicle actual external temperature to the calculated vehicle external temperature difference, thereby updating the ambient temperature displayed by the vehicle;

[0081] If the current vehicle speed is greater than the first vehicle speed threshold, the current vehicle ambient temperature calculation value is updated at a third set interval according to a second ratio of the actual vehicle external temperature to the calculated vehicle external temperature difference, thereby updating the ambient temperature displayed by the vehicle.

[0082] Specifically, when the current vehicle external temperature is in a decreasing stage and the current vehicle speed is greater than the third vehicle speed threshold, the corresponding scenario is high-speed driving after a cold car start. At this time, the external temperature is relatively stable. In order to eliminate the influence of tunnels, sunlight angles, etc., it is adjusted to the third ratio based on the actual vehicle external temperature and the calculated vehicle external temperature difference, and is updated once at the first set interval to meet the scenario usage.

[0083] For example, when the current vehicle external temperature is in a declining stage, such as the vehicle speed is greater than 120 kilometers per hour, the ambient temperature is updated every 60 seconds according to the value collected by the outdoor temperature sensor, and each update is one-fifth of the difference between the actual collected external temperature and the external temperature in the algorithm, that is, one-fifth of the difference between the actual collected external temperature and the external temperature in the algorithm is added to the current ambient temperature display value; the corresponding scenario is high-speed driving after a cold car is started. At this time, the outside temperature is relatively stable. In order to eliminate the influence of tunnels, sunlight angles, etc., it is adjusted to update once a minute to meet the scenario usage.

[0084] Specifically, when the current vehicle external temperature is in a decreasing stage and the current vehicle speed is not greater than the third vehicle speed threshold, the corresponding scenario is medium and low speed driving after a cold car start. At this time, the ambient temperature update frequency is adjusted taking into account the engine thermal reflux filtering. According to the second ratio of the actual vehicle external temperature and the calculated vehicle external temperature difference, the update is performed at a frequency of the third set interval to meet the scenario requirements.

[0085] For example, when the current vehicle outside temperature is in a declining stage, such as the vehicle speed is less than or equal to 120 kilometers per hour, the ambient temperature is updated every 0.6 seconds according to the value collected by the outdoor temperature sensor, and each update is half of the difference between the actual collected outside temperature and the outside temperature in the algorithm, that is, the current ambient temperature display value is added with half of the actual collected outside temperature and the outside temperature in the algorithm.

[0086] It should be noted that the first temperature threshold, the first vehicle speed threshold, the second vehicle speed threshold, the third vehicle speed threshold, the first ratio, the second ratio, the third ratio, the first set interval, the second set interval, etc. can be set accordingly according to the actual vehicle conditions, and this embodiment does not specifically limit these specific values.

[0087] Among them, the third speed threshold is greater than the first speed threshold, and the first speed threshold is greater than the second speed threshold; the first ratio is smaller than the third ratio, and the third ratio is smaller than the second ratio; the first set interval is greater than the second set interval, and the second set interval is greater than the third set interval.

[0088] The present application also provides a vehicle ambient temperature display confirmation system, comprising:

[0089] A judgment module, which is used to determine whether the current vehicle external temperature is in a rising stage;

[0090] A first display module is used for, when the engine water temperature is greater than a first temperature threshold, if the current vehicle speed is less than the first vehicle speed threshold, and the compressor in the vehicle air conditioning system is in an inoperative state, using the collected evaporator temperature as the ambient temperature displayed by the vehicle;

[0091] A second display module is used to update the ambient temperature displayed by the vehicle according to the difference between the actual vehicle external temperature and the calculated vehicle external temperature when the engine water temperature is not greater than the first temperature threshold and the vehicle KL15 does not have a power-on action and the current vehicle speed is not less than a second vehicle speed threshold;

[0092] The third display module is used to use the collected evaporator temperature as the ambient temperature displayed by the vehicle if the vehicle speed is less than a second vehicle speed threshold and the compressor in the vehicle air-conditioning system is in an off-state; wherein the first vehicle speed threshold is greater than the second vehicle speed threshold.
