Description

Technical Field

[0001] This invention belongs to the technical field of vehicle air conditioning, and particularly relates to a method, system and vehicle for displaying and confirming vehicle ambient temperature. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] With the rapid development of the automotive industry and the continuous improvement of people's living standards, the concepts of artificial intelligence, green travel, and low-carbon environmental protection have become the main choices for many cities and users' travel solutions. In particular, the highlights of intelligent and energy-saving designs remain the focus of current market attention. The development of thermal management systems has also been significantly affected. Currently, intelligent control and intelligent air conditioning applications and functions are widespread in many vehicle models. However, the realization of these scenarios and functions relies on automatic air conditioning configurations. In automatic air conditioning configurations, the accurate acquisition and filtering of ambient temperature are the core algorithms of each OEM or technology supplier.

[0004] Currently, there are two main design directions for in-vehicle ambient temperature displays. One is simulation calculation, which mainly relies on information collected from the vehicle interior temperature, evaporator temperature, engine coolant temperature, vehicle speed signal, sunlight intensity, etc., to calculate the real-time ambient temperature through relatively complex model algorithms, and then completes the application after combining it with real vehicle calibration and verification. The other is to use outdoor temperature sensor hardware to collect data, and then combine it with software filtering algorithms and real vehicle calibration and verification before application. The latter is more widely used, but it cannot fully cover some real vehicle scenarios, which means that automatic air conditioning cannot achieve full-scenario functionality. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a method, system and vehicle for displaying and confirming vehicle ambient temperature, thereby enabling real-time and accurate display of vehicle ambient temperature.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a method for displaying and confirming the ambient temperature of a vehicle, comprising:

[0008] When the outside temperature of the vehicle is rising, if the engine coolant 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 not working, then the collected evaporator temperature will be used as the ambient temperature displayed by the vehicle.

[0009] If the engine coolant temperature is not greater than the first temperature threshold, the vehicle KL15 does not have an power-on action, and the current vehicle speed is not less than the second vehicle speed threshold, then the ambient temperature displayed by the vehicle is updated according to the difference between the actual outside temperature of the vehicle and the calculated outside temperature of the vehicle.

[0010] If the vehicle speed is less than the second vehicle speed threshold 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; wherein the first vehicle speed threshold is greater than the second vehicle speed threshold.

[0011] When the vehicle's outside temperature is decreasing, the ambient temperature displayed on the vehicle is updated based on the difference between the actual outside temperature and the calculated outside temperature.

[0012] Preferably, it further includes: when the vehicle's outside temperature is rising, if the engine coolant temperature is greater than the first temperature threshold and the current vehicle speed is not less than the first vehicle speed threshold, then the calculated value of the current vehicle ambient temperature is updated based on the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, thereby updating the ambient temperature displayed by the vehicle.

[0013] Preferably, the method further includes: when the vehicle's outside temperature is rising, if the engine coolant temperature is greater than the first temperature threshold, and the current vehicle speed is less than the first vehicle speed threshold, and the compressor in the vehicle's air conditioning system is in operation, then the ambient temperature displayed by the vehicle will not be updated.

[0014] Preferably, if the current vehicle speed is not less than the second vehicle speed threshold, the calculated vehicle ambient temperature is updated based on the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, thereby updating the ambient temperature displayed by the vehicle. Specifically:

[0015] If the current vehicle speed is not less than the first vehicle speed threshold, the calculated value of the current vehicle ambient temperature is updated at a first set interval according to the first ratio of the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, thereby updating the ambient temperature displayed by the vehicle.

[0016] If the current vehicle speed is less than the first vehicle speed threshold and not less than the second vehicle speed threshold, the calculated vehicle ambient temperature is updated at a second set interval according to a second ratio of the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, thereby updating the ambient temperature displayed by the vehicle; wherein, the first set interval is greater than the second set interval, and the first ratio is less than the second ratio.

[0017] Preferably, it further includes: when the vehicle's outside temperature is rising, and the engine coolant temperature is not greater than the first temperature threshold, and the vehicle KL15 is powered on, updating the ambient temperature displayed by the vehicle based on the vehicle's outside temperature collection value.

[0018] Preferably, the method further includes: when the vehicle's outside temperature is rising, if the engine coolant temperature is not greater than the first temperature threshold, the vehicle KL15 is not powered on, the current vehicle speed is less than the second vehicle speed threshold, and the compressor in the vehicle's air conditioning system is in operation, then the ambient temperature displayed by the vehicle will not be updated.

[0019] Preferably, the determination of whether the current vehicle outside temperature is in a rising or falling phase is as follows:

[0020] Calculate the difference between the real-time outside temperature of the vehicle and the ambient temperature value stored in the vehicle.

[0021] If the calculated difference is greater than zero, the vehicle's outside temperature is currently in the rising phase.

[0022] If the calculated difference is less than zero, the vehicle's external temperature is currently in a decreasing phase.

[0023] Preferably, when the vehicle's outside temperature is in a decreasing phase, the displayed ambient temperature is updated based on the difference between the actual and calculated outside temperature. Specifically:

[0024] When the vehicle's outside temperature is decreasing, if the current vehicle speed is not less than the third vehicle speed threshold, the calculated vehicle ambient temperature is updated at a first set interval according to the third ratio of the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, thereby updating the ambient temperature displayed by the vehicle.

[0025] If the current vehicle speed is less than the third vehicle speed threshold, the calculated vehicle ambient temperature is updated at a third set interval according to the second ratio of the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, thereby updating the ambient temperature displayed by the vehicle; wherein the third vehicle speed threshold is greater than the first vehicle speed threshold.

[0026] In a second aspect, the present invention provides a vehicle ambient temperature display and confirmation system, comprising:

[0027] The judgment module is used to determine whether the current vehicle outside temperature is in the rising phase.

[0028] The first display module is used to take the collected evaporator temperature as the ambient temperature of the vehicle when the engine coolant temperature is greater than a first temperature threshold, the current vehicle speed is less than a first vehicle speed threshold, and the compressor in the vehicle air conditioning system is not working.

[0029] The second display module is used to update the ambient temperature displayed by the vehicle based on the difference between the actual outside temperature of the vehicle and the calculated outside temperature of the vehicle when the engine coolant temperature is not greater than the first temperature threshold and the vehicle KL15 is not powered on, and the current vehicle speed is not less than the second vehicle speed threshold.

[0030] The third display module is used to take the collected evaporator temperature as the ambient temperature displayed by the vehicle if the vehicle speed is less than the second vehicle speed threshold and the compressor in the vehicle air conditioning system is not working; wherein the first vehicle speed threshold is greater than the second vehicle speed threshold.

[0031] Thirdly, the present invention provides a vehicle employing the vehicle ambient temperature display and confirmation method described above.

[0032] The above one or more technical solutions have the following beneficial effects:

[0033] This invention comprehensively judges the external environment of the vehicle by considering factors such as engine coolant temperature, vehicle speed, the status of the compressor in the vehicle's air conditioning system, and whether the vehicle's KL15 is powered on. This effectively covers different usage scenarios, including seasonal changes, vehicle speed changes, road environment changes, parking and exiting scenarios, sun exposure scenarios, and vehicle immersion scenarios, thereby achieving real-time and accurate display of the vehicle's ambient temperature. In addition, when the vehicle meets certain conditions and there is fresh airflow, the confirmation of the displayed ambient temperature can effectively avoid the influence of engine heat recirculation.

[0034] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0039] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0040] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations of the present invention.

[0041] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0042] Before providing a detailed explanation of the vehicle heating control method provided in the embodiments of this application, the application scenarios and implementation environment involved in the embodiments of this application will be introduced first.

[0043] For current automotive ambient temperature acquisition and display methods, whether using analog calculations or relying on outdoor temperature sensor hardware, it is difficult to distinguish between the temperature rise caused by engine heat recirculation and the actual ambient temperature rise. Especially during vehicle idling, there is currently no effective way to filter the impact of engine heat recirculation on the ambient temperature acquisition, because it is impossible to distinguish between the actual ambient temperature rise and the rise in the acquired value caused by engine heat recirculation. Software strategies either filter out both scenarios or acquire both, but either method will result in ambient temperature distortion.

[0044] Based on this, this application provides a vehicle ambient temperature display and confirmation method that can effectively cover different usage environments such as seasonal changes, vehicle speed changes, road environment changes, inbound and outbound scenarios, sun exposure scenarios, and vehicle immersion scenarios, thereby achieving real-time and accurate display of vehicle ambient temperature; and can also effectively avoid the influence of engine heat backflow.

[0045] The results of one implementation environment of this embodiment will be described. This 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 (Negative Temperature Coefficient) thermistor acquisition circuit. Since it's typically powered by 5V, a pull-up resistor and filter circuit are used before connecting it to the acquisition circuit to complete the hardware interface design. The outdoor temperature sensor is usually installed at the opening of the front grille, close to the radiator, to measure the ambient temperature. Its resistance changes with the ambient temperature. The MCU's hardware acquisition circuit collects the different voltages, converts them into resistance, and calculates the actual temperature using a lookup table. The evaporator temperature sensor is installed on the evaporator, near the windshield wipers, to measure the evaporator temperature. The engine temperature sensor is typically installed on the water jacket of the engine block or cylinder head to measure the engine coolant temperature. The electronic control unit receives the values ​​measured by the ambient temperature sensor, evaporator temperature sensor, and engine temperature sensor, performs a series of processing calculations, and obtains the vehicle's ambient temperature displayed on the display module.

[0047] It should be noted that the application scenarios and implementation environments described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the emergence of new application scenarios and the evolution of implementation environments, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0048] The following is a detailed explanation of the vehicle ambient temperature display and confirmation method provided in this embodiment.

[0049] Figure 1 This embodiment provides a flowchart of a vehicle ambient temperature display and confirmation method, which includes:

[0050] Step 101: Determine that the vehicle's outside temperature is currently in the rising phase;

[0051] Step 1011: When the engine coolant 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's air conditioning system is not working, the collected evaporator temperature is used as the ambient temperature displayed by the vehicle.

[0052] Step 1012: When the engine coolant 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 outside temperature of the vehicle and the calculated outside temperature of the vehicle.

[0053] Step 1013: If the vehicle speed is less than the second vehicle speed threshold and the compressor in the vehicle's air conditioning system is not working, then the collected evaporator temperature is taken 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: If the current vehicle outside temperature is in a decreasing phase, update the ambient temperature displayed on the vehicle based on the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature.

[0055] In this application, the determination of whether the current vehicle outside temperature is in a rising or falling phase is specifically made by calculating the difference between the real-time collected value of the vehicle outside temperature and the ambient temperature value stored in the vehicle.

[0056] If the calculated difference is greater than zero, the vehicle's outside temperature is currently in the rising phase.

[0057] If the calculated difference is less than zero, the vehicle's external temperature is currently in a decreasing phase.

[0058] In this application, under the condition that the vehicle power supply is effective, the comparison between the vehicle's collected outside temperature and the vehicle's 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, i.e., the vehicle's outside temperature, is in the rising range. If the difference is less than zero, it is determined that the current vehicle collected temperature, i.e., the vehicle's outside temperature, is in the falling range.

[0059] In step 1011 of this application, when the outside temperature of the vehicle is rising, the engine coolant 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 not working, the matching scenario is that the vehicle is slowly driven into a heated garage at low speed after being warmed up in winter. At this time, because the engine heat recirculation has strong heat radiation on the outdoor temperature sensor, and there is no fresh air flow at the location where the outdoor temperature sensor is located, the airflow of the air conditioning fresh air circulation can effectively pass through the evaporator core. Therefore, 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's ambient temperature.

[0060] For example, if the engine coolant temperature is greater than 50°C, and the current vehicle speed is less than 30 km / h, and the compressor in the vehicle's air conditioning system is not working, then the collected evaporator temperature will be used as the ambient temperature displayed by the vehicle.

[0061] In step 1012 of this application, specifically: when the engine coolant 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 first vehicle speed threshold, the calculated value of the current vehicle ambient temperature is updated at a first set interval according to the first ratio of the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, thereby updating the ambient temperature displayed by the vehicle.

[0062] Specifically, vehicle KL15 can refer to the air conditioning power supply. When the engine coolant temperature is not greater than the first temperature threshold, and vehicle KL15 is not powered on, and the current vehicle speed is not less than the first vehicle speed threshold, the corresponding scenario is that the vehicle continues to drive after idling. By updating the current vehicle ambient temperature calculation value at a first set interval based on the first ratio of the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, the ambient temperature displayed by the vehicle is updated, which can effectively filter the heat backflow influence around the outdoor temperature sensor during idling.

[0063] It should be noted that the first ratio and the first set interval can be set according to the actual vehicle situation. 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 coolant 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 km / h, the ambient temperature display and calculated value are updated every 60 seconds according to the value collected by the outdoor temperature sensor. However, each update is based on one-sixth of the difference between the actual outside temperature and the outside temperature in the algorithm, which is the current ambient temperature display value plus one-sixth of the difference between the actual outside temperature and the outside temperature in the algorithm. Here, the outside temperature in the algorithm refers to the value in the difference calculation process, and the outside temperature in the first algorithm is the valid value of the ambient temperature in the previous frame. The matching corresponding scenario is that the vehicle continues to drive after idling, and the outside temperature is updated once a minute, with each update being one-sixth of the difference, effectively filtering out the influence of heat backflow around the outdoor temperature sensor during idling.

[0065] When the engine coolant temperature is not greater than the first temperature threshold and the vehicle KL15 is not powered on, if the current vehicle speed is less than the first vehicle speed threshold and not less than the second vehicle speed threshold, the calculated vehicle ambient temperature is updated at a second set interval according to a second ratio of the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, thereby updating the ambient temperature displayed by the vehicle; 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 coolant temperature is not greater than the first temperature threshold, and the vehicle KL15 is not powered on, and the current vehicle speed is less than the first vehicle speed threshold and not less than the second vehicle speed threshold, the matched scenario is that the vehicle continues to drive slowly at low speed after idling, and the outside temperature is updated according to the second set interval, effectively filtering the heat backflow influence around the outside temperature sensor during idling and increasing the update frequency.

[0067] For example, when the vehicle is in the stage of rising external temperature, the engine coolant temperature is less than or equal to 50°C, the KL15 power supply remains unchanged, and the vehicle speed is less than 30 km / h and greater than or equal to 5 km / h, the ambient temperature display and calculated value are updated every 30 seconds according to the value collected by the outdoor temperature sensor. However, each update is half of the difference between the actual external temperature and the external temperature in the algorithm. That is, the current ambient temperature display value is plus half of the difference between the actual external temperature and the external temperature in the algorithm. Here, the external temperature in the algorithm refers to the value of the difference calculation process. The external temperature in the first algorithm is the valid value of the ambient temperature in the previous frame. The matching corresponding scenario is that the vehicle continues to drive slowly at low speed after idling. The external temperature is updated every half minute, which effectively filters the heat backflow influence around the outdoor temperature sensor during idling and improves the update frequency.

[0068] In step 1013, specifically: when the vehicle's outside temperature is rising, the engine coolant temperature is not greater than the first temperature threshold, the vehicle KL15 is not powered on, the current vehicle speed is less than the second vehicle speed threshold, and the compressor in the vehicle's air conditioning system is off. The corresponding scenario is the idle-to-idle condition. At this time, because the engine's heat recirculation strongly radiates heat around the outdoor temperature sensor, no fresh airflow passes through. However, the airflow from the air conditioning fresh air circulation can effectively pass through the evaporator core. Therefore, the evaporator temperature sensor's collected value can replace the outdoor temperature sensor's collected value to complete the display and calculation of the ambient temperature.

[0069] For example, when the vehicle's outside temperature is rising, the engine coolant temperature is less than or equal to 50°C, the KL15 power supply remains unchanged, the vehicle speed is less than 5 kilometers per hour, and the compressor is off, the evaporator temperature sensor value is used to replace the outdoor temperature sensor value to complete the ambient temperature calculation and display.

[0070] This application also includes: when the vehicle's outside temperature is rising, the engine coolant temperature is not greater than the first temperature threshold, the vehicle KL15 is not powered on, and 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 operation, then the ambient temperature displayed by the vehicle will not be updated.

[0071] Specifically, when the vehicle's outside temperature is rising, the engine coolant temperature is not greater than the first temperature threshold, the vehicle KL15 is not powered on, the current vehicle speed is less than the second vehicle speed threshold, and the compressor in the vehicle's air conditioning system is working, the ambient temperature is not updated. In this case, the EEP stored value is used to complete the display and calculation of the ambient temperature. The corresponding scenario is the transition from idle to idle with the air conditioning on. Because the ambient temperature collected before idling is relatively accurate, the temperature value stored in the EEP is also the effective ambient temperature of the previous frame, i.e., the ambient temperature collected during driving. Therefore, in this scenario, the collected value is filtered, and the stored value method is more appropriate.

[0072] For example, when the vehicle's outside temperature is rising, the engine coolant temperature is less than or equal to 50°C, the KL15 power supply remains unchanged, the vehicle speed is less than 5 kilometers per hour, and the compressor is in operation, the ambient temperature is not updated. In this case, the ambient temperature is displayed and calculated using the EEP stored value.

[0073] This application also includes: when the vehicle temperature is in the rising range, and the engine coolant 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's air conditioning system is working, then the displayed ambient temperature of the vehicle will not be updated. This corresponds to the scenario of a vehicle idling after warming up in spring or autumn. Because the ambient temperature collected during driving is relatively accurate, the temperature value stored in the EEP (Electronic Temperature Buffer) is also the valid ambient temperature of the previous frame, i.e., the ambient temperature collected during driving. Therefore, using the stored value method is more suitable for filtering the collected values ​​in this scenario.

[0074] For example, when the vehicle temperature is in the rising range, the engine coolant 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. In this case, the EEP stored value is used to complete the display and calculation of the ambient temperature.

[0075] This application also includes: when the current vehicle outside temperature is rising, the engine coolant 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 tropical climbing condition, where the engine speed is high and the engine temperature rises quickly, but the vehicle speed is not high. At this time, a first set interval is used to update the engine temperature according to the first ratio of the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, which can effectively filter the influence of engine heat recirculation.

[0076] For example, when the vehicle is in the range of rising external temperature, with engine coolant temperature greater than 50°C and vehicle speed greater than or equal to 30 km / h, the displayed and calculated ambient temperature values ​​are updated every 60 seconds based on the outdoor temperature sensor readings. However, each update adds one-sixth of the difference between the actual and calculated external temperatures. In other words, the displayed ambient temperature is increased by adding one-sixth of the difference between the actual and calculated external temperatures to the current displayed ambient temperature value. The external temperature in the algorithm refers to the difference calculation process value, and the initial external temperature in the algorithm is the valid ambient temperature value of the previous frame. The corresponding scenario is tropical hill climbing, where the engine speed is high and the engine temperature rises quickly, but the vehicle speed is not high. In this case, updating once per minute with one-sixth of the difference each time can effectively filter out the influence of engine heat recirculation.

[0077] This application also includes: when the current vehicle outside temperature is rising, the engine coolant temperature is not greater than the first temperature threshold, the vehicle KL15 changes from OFF to ON, the corresponding scenario is the vehicle parked outside, and the ambient temperature is updated after the user enters the vehicle and starts the vehicle.

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

[0079] In step 102, specifically: when the vehicle's outside temperature is in a decreasing phase, the calculated vehicle ambient temperature is updated based on the difference between the actual outside temperature and the calculated outside temperature, thereby updating the displayed ambient temperature of the vehicle. Specifically:

[0080] When the vehicle's outside temperature is decreasing, if the current vehicle speed is not less than the third vehicle speed threshold, the calculated vehicle ambient temperature is updated at a first set interval according to the third ratio of the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, thereby updating the ambient temperature displayed by the vehicle.

[0081] If the current vehicle speed is greater than the first vehicle speed threshold, the calculated vehicle ambient temperature value is updated at a third set interval based on a second ratio of the difference between the actual vehicle outside temperature and the calculated vehicle outside temperature, thereby updating the ambient temperature displayed by the vehicle.

[0082] Specifically, when the vehicle's external temperature is decreasing and the current vehicle speed is greater than the third speed threshold, the corresponding scenario is high-speed driving after a cold start. At this time, the external temperature is relatively stable. In order to eliminate the influence of tunnels, sunlight angle, etc., the system is adjusted to update once at the first set interval based on the third ratio of the difference between the actual vehicle external temperature and the calculated vehicle external temperature, so as to meet the needs of the scenario.

[0083] For example, when the vehicle's outside temperature is decreasing, such as when the vehicle speed is greater than 120 kilometers per hour, the ambient temperature is updated every 60 seconds based on the outdoor temperature sensor readings. Each update adds one-fifth of the difference between the actual measured outside temperature and the outside temperature in the algorithm to the current displayed ambient temperature value. The corresponding scenario is high-speed driving after a cold start, when the outside temperature is relatively stable. To eliminate the influence of tunnels, sunlight angles, etc., the update is adjusted to once per minute to meet the needs of the scenario.

[0084] Specifically, when the vehicle's external temperature is decreasing and the current vehicle speed is no greater than the third vehicle speed threshold, the corresponding scenario is low-to-medium speed driving after a cold start. At this time, the ambient temperature update frequency is adjusted by taking into account the engine's thermal recirculation filter. Based on the second ratio of the difference between the actual vehicle's external temperature and the calculated vehicle external temperature, the update is performed at a third set interval to meet the scenario requirements.

[0085] For example, when the vehicle's outside temperature is decreasing, such as when 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. 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 increased by half of the difference between 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, as well as the first set interval and the second set interval, can be set according to the actual vehicle conditions. This embodiment does not specifically limit these values.

[0087] Among them, the third speed threshold is greater than the first speed threshold, the first speed threshold is greater than the second speed threshold; the first ratio is less than the third ratio, the third ratio is less 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] This application also provides a vehicle ambient temperature display and confirmation system, including:

[0089] The judgment module is used to determine whether the current vehicle outside temperature is in the rising phase.

[0090] The first display module is used to take the collected evaporator temperature as the ambient temperature of the vehicle when the engine coolant temperature is greater than a first temperature threshold, the current vehicle speed is less than a first vehicle speed threshold, and the compressor in the vehicle air conditioning system is not working.

[0091] The second display module is used to update the ambient temperature displayed by the vehicle based on the difference between the actual outside temperature of the vehicle and the calculated outside temperature of the vehicle when the engine coolant temperature is not greater than the first temperature threshold and the vehicle KL15 is not powered on, and the current vehicle speed is not less than the second vehicle speed threshold.

[0092] The third display module is used to take the collected evaporator temperature as the ambient temperature displayed by the vehicle if the vehicle speed is less than the second vehicle speed threshold and the compressor in the vehicle air conditioning system is not working; wherein the first vehicle speed threshold is greater than the second vehicle speed threshold.

Furthermore, memory can include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device. Accordingly, memory can also include a memory controller to provide access to the memory for the processor and input units.

[0097] The input unit can be used to receive input numerical or character information, and to generate keyboard, mouse, joystick, optical, or trackball signal inputs related to user settings and function control. Specifically, the input unit may include a touch-sensitive surface and other input devices. A touch-sensitive surface, also known as a touch display or touchpad, can collect user touch operations on or near it (such as user operations using fingers, styluses, or any suitable object or accessory on or near the touch-sensitive surface) and drive corresponding connected devices according to a pre-set program. Optionally, the touch-sensitive surface may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch location and the signal generated by the touch operation, transmitting the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to the processor, and can receive and execute commands from the processor. Furthermore, various types of touch-sensitive surfaces, such as resistive, capacitive, infrared, and surface acoustic wave, can be used. In addition to the touch-sensitive surface, the input unit may also include other input devices. Specifically, other input devices may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc.

[0098] The display unit can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces (GUIs) of the vehicle. These GUIs can be composed of graphics, text, icons, video, and any combination thereof. The display unit may include a display panel, optionally configured as an LCD (Liquid Crystal Display), OLED (Organic Light-Emitting Diode), or similar display panel. Furthermore, a touch-sensitive surface may cover the display panel. When the touch-sensitive surface detects a touch operation on or near it, it transmits the information to the processor to determine the type of touch event. Subsequently, the processor provides corresponding visual output on the display panel based on the type of touch event. The touch-sensitive surface and the display panel are implemented as two separate components to achieve input and output functions; however, in some embodiments, the touch-sensitive surface and the display panel can be integrated to achieve both input and output functions.

[0099] The vehicle may also include at least one sensor, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor can adjust the brightness of the display panel according to the ambient light level, and the proximity sensor can turn off the display panel and / or backlight when the vehicle is moved close to the ear. As a type of motion sensor, a gravity acceleration sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition functions (such as pedometers, taps), etc. Other sensors that the vehicle may also be equipped with, such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be elaborated here.

[0100] Audio circuitry, speakers, and microphones provide an audio interface between the user and the vehicle. The audio circuitry converts received audio data into electrical signals, which are then transmitted to the speakers, where they are converted into sound signals for output. Conversely, the microphone converts collected sound signals into electrical signals, which are received by the audio circuitry, converted back into audio data, and then processed by a processor. The audio data is then transmitted via RF circuitry to, for example, another vehicle, or output to memory for further processing. The audio circuitry may also include an earphone jack to facilitate communication between external headphones and the vehicle.

[0101] WiFi is a short-range wireless transmission technology. Vehicles using WiFi modules can help users send and receive emails, browse web pages, and access streaming media, providing wireless broadband internet access. Although a WiFi module is shown, it is understood that it is not an essential component of the vehicle and can be omitted as needed without altering the essence of the invention.

[0102] The processor is the control center of the vehicle, connecting various parts of the phone via various interfaces and lines. It executes software programs and / or modules stored in memory, and calls data stored in memory to perform various vehicle functions and process data, thereby providing overall monitoring of the phone. Optionally, the processor may include one or more processing cores; preferably, the processor may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may also not be integrated into the processor.

[0103] The vehicle also includes a power supply (such as a battery) that powers various components. Preferably, the power supply can be connected to the processor logic through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system. The power supply may also include one or more DC or AC power sources, a recharging system, a power fault detection circuit, a power converter or inverter, a power status indicator, and any other components.

[0104] Although not shown, the vehicle may also include cameras, Bluetooth modules, etc., which will not be described in detail here. Specifically, in this embodiment, the vehicle's display unit is a touch screen display, and the vehicle also includes a memory and one or more programs, wherein one or more programs are stored in the memory and configured to be executed by one or more processors. The one or more programs include methods for performing the methods shown in the above embodiments.

[0105] This invention also provides a computer-readable storage medium applied to a terminal. The computer-readable storage medium stores at least one instruction, at least one program, code set, or instruction set. The instruction, program, code set, or instruction set is loaded and executed by a processor to implement the operations performed by the vehicle in the vehicle display method of the above embodiments.

[0106] Those skilled in the art will understand that all or part of the steps of the above embodiments can be implemented by hardware or by a program instructing related hardware. The program can be stored in a computer-readable storage medium, such as a read-only memory, a disk, or an optical disk.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
