Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings. The particular methods of operation in the method embodiments may also be applied to apparatus embodiments or system embodiments.

In the description of the present application "plurality" is understood to mean "at least two". "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. A is connected with B and can represent: a and B are directly connected and A and B are connected through C. In addition, in the description of the present application, the terms "first," "second," and the like are used for descriptive purposes only and are not intended to indicate or imply relative importance nor order to be construed.

In order to facilitate those skilled in the art to better understand the technical solutions provided in the embodiments of the present application, the following technical terms are briefly described as follows:

an EEPROM (Electrically Erasable Programmable read only memory) refers to a charged Erasable Programmable read only memory. The memory chip is a memory chip with no data loss after power failure. The EEPROM can be erased and reprogrammed on a computer or a special device. Typically for plug and play.

The following briefly introduces the design concept of the embodiments of the present application.

At present, the display of the ambient temperature outside the automobile on an automobile instrument is almost a necessary item of instrument functions. The temperature value display has two main purposes, namely, a driver can better know the external environment temperature, a certain reference effect is provided for driving operation, and driving safety is facilitated; and secondly, the device is used for controlling and calculating the comfort of the automatic air conditioner, so that the automatic air conditioner can quickly realize the adjustment of the temperature in the vehicle.

Because the external environment temperature sensor is generally installed in the vehicle air inlet grille, the air flow at the position after the vehicle stops is very small, the external environment temperature sensor is easily radiated by the waste heat of the engine, the acquired value of the external environment temperature sensor deviates from the real natural temperature value of the surrounding environment of the vehicle, the acquired value is directly used for instrument display and automatic air conditioning comfort control, the judgment of the driver on the external environment temperature can be influenced, and the driving state of the driver and the efficiency of the automatic air conditioning comfort control are influenced. Therefore, it is necessary to analyze and process the value collected by the external ambient temperature sensor before using it.

In the existing automobile environment temperature judging scheme, whether the acquired value of the external environment temperature is distorted is judged by judging the difference value of the acquired value of the external environment temperature and the acquired value of the engine water temperature, and if the acquired value of the external environment temperature is distorted, the final display value is obtained by correcting and processing T3 data (the T3 data is from a table obtained by recording the stop of the vehicle after the vehicle runs at high speed). However, under different environments, the corresponding relation between the engine water temperature and the temperature change at the external environment temperature sensor is not fixed, and no stable rule is available, and the working condition related to the scheme cannot cover all use scenes of a user vehicle, so that the misjudgment of whether the external environment temperature acquisition value is distorted or not is large by using the difference value of the engine water temperature and the external environment temperature acquisition value, and the distorted value is easily sent to an instrument for displaying; in addition, when the T3 data is used in the data correction scheme after the external environment temperature collection value is determined to be distorted, the table data source of the T3 is also unrepresentative, and the error of the temperature value displayed by the final instrument is large.

In view of this, the method for analyzing and displaying the temperature outside the vehicle provided by the application only adopts the time condition to determine whether the collected value of the temperature sensor outside the vehicle is distorted, and determines that the temperature sensor outside the vehicle is not influenced by the radiation of the engine within 1 minute of parking, and at the moment, the collected value of the temperature sensor outside the vehicle can be displayed on the instrument. Since the radiation speed of the engine temperature during this stop time is not extremely high, the detected value of the vehicle exterior temperature sensor cannot be increased. The method can improve the effectiveness of displaying the temperature value of the automobile instrument, and avoids the problem that the existing scheme obtains data from some irregular temperature change relations, so that unreal environment temperature acquisition values are displayed on the instrument.

The method provided by the embodiment of the application is further explained in detail in the following with reference to the attached drawings.

Referring to fig. 1, an embodiment of the present application provides a method for analyzing and displaying an outside temperature, which includes the following specific processes:

step 101: responding to the ON gear electricity ON the vehicle, and acquiring a collected value of a temperature sensor outside the vehicle and a stored value of the environmental temperature in a memory;

in the embodiment of the application, when a vehicle is powered ON by one-touch start, the ignition switch enters an ON (ignition signal IG) state from an OFF (ignition signal IG) state and keeps the ON (ignition signal IG) state, the air conditioner controller starts to acquire the acquired value Tnow of the external temperature sensor and reads the stored value Tepm of the environmental temperature in the EEPROM, and judges whether the acquired value Tnow of the external temperature sensor is larger than the stored value Tepm of the environmental temperature in the EEPROM or not.

In one possible embodiment, if the detected value Tnow of the external temperature sensor is less than or equal to the stored value Tepm of the ambient temperature in the EEPROM, the detected value Tnow of the external temperature sensor is directly displayed on the display device of the vehicle.

It is worth to be noted that when the acquired value Tnow of the external temperature sensor is less than or equal to the stored value Tepm of the ambient temperature in the EEPROM, it is indicated that the external temperature sensor is not affected by the engine radiation, and at this time, the acquired value Tnow of the external temperature sensor is almost equal to the true value of the external ambient temperature, and can be directly used for displaying on the instrument of the vehicle.

In a possible embodiment, if the value Tnow collected by the external temperature sensor is greater than the stored value Tepm of the ambient temperature in the EEPROM, the operation of step 102 described below is performed.

Step 102: if the acquired value is larger than the stored value, acquiring parking time and determining the state of the vehicle;

in the embodiment of the present application, the parking time refers to the time from when the vehicle is powered off to when the power is turned ON again, and the state of the vehicle is classified into the following two states according to the parking time.

The first state: and a cold state, which means that the vehicle is stopped for less than 1 minute or more than 60 minutes. When the parking time is less than 1 minute, the temperature radiation speed of the engine is not very high, and the temperature sensor outside the vehicle cannot be influenced; when the parking time is more than 60 minutes, the engine is completely cooled down, and heat cannot be generated to influence the temperature sensor outside the automobile.

And a second state: the warm-up state indicates that the vehicle has been stopped for a period of time of 1 minute or more and 60 minutes or less. When the parking time is more than or equal to 1 minute and less than or equal to 60 minutes, the engine is not completely cooled down, and the residual heat of the engine can enable the collection value of the temperature sensor outside the automobile to be higher than the actual ambient temperature value outside the automobile.

In one possible embodiment, the stored value Tepm of the ambient temperature in the EEPROM is displayed on a display device of the vehicle when the state of the vehicle is determined to be a hot vehicle state.

Because the engine still has the waste heat under the vehicle state of heating, the temperature value that the temperature sensor gathered outside the car can receive the influence of engine waste heat this moment, leads to the value Tnow of gathering to distort, has great error with the real temperature value of the environment outside the car. At this time, the stored value Tepm of the environmental temperature in the EEPROM is closer to the real temperature value of the environment outside the vehicle, so the stored value Tepm is displayed on the vehicle display device to reduce the error.

In one possible embodiment, when the state of the vehicle is a cold state, the following operation of step 103 is performed.

Step 103: if the vehicle is in a cold state, acquiring a water temperature value of the engine, and judging whether the water temperature value of the engine is smaller than a preset water temperature value or not;

specifically, when the vehicle is in a cold state, the air conditioner controller reads the engine water temperature value Tbor and judges whether the read engine water temperature value Tbor is smaller than a preset water temperature value, wherein the preset water temperature value can adopt 20 ℃ as a reference.

It should be noted that the normal water temperature value of the engine is generally 80 ℃ to 90 ℃, when the water temperature value Twor of the engine is less than 20 ℃, the environment temperature outside the vehicle is shown to be in a low temperature state, at this time, the temperature sensor outside the vehicle is not influenced by the waste heat of the engine and the engine room, and the value acquired by the temperature sensor outside the vehicle is the current real environment value. In a possible implementation manner, if the engine water temperature value Twor is not less than the preset water temperature value, it is determined whether the engine water temperature value Twor is less than the collected value Tnow of the vehicle-exterior temperature sensor. If the engine water temperature value Twor is smaller than the acquisition value Tnow of the vehicle outside temperature sensor, displaying the engine water temperature value Twor on a display device of the vehicle; and if the water temperature value Twor of the engine is not less than the acquired value Tnow of the temperature sensor outside the vehicle, displaying the acquired value Tnow of the temperature sensor outside the vehicle on a display device of the vehicle. In other words, the engine water temperature value Twor and the collected value Tnow of the vehicle exterior temperature sensor are compared, and the smaller of the two values is displayed on the vehicle display device.

In one possible embodiment, if the engine water temperature value Twor is less than the preset water temperature value, the following operation of step 104 is performed.

Step 104: and if the water temperature value of the engine is smaller than the preset water temperature value, displaying the acquired value on vehicle display equipment.

Specifically, the collected value Tnow is assigned to a display value, and the display value is displayed on a display device, where the display device may be an automobile meter.

The logic sequence of the method for analyzing and displaying the outside temperature provided by the present application is further described in detail with reference to fig. 2 by taking the preset water temperature as 20 ℃ as an example.

Referring to fig. 2, initially, the vehicle is powered ON by a key-ON, and the ignition switch state is changed from OFF (IG) to ON (IG) and remains in the ON (IG) state. When the air conditioner controller recognizes that the ignition switch state enters and is kept in an ON (IG) state, the temperature value of the temperature sensor outside the vehicle is collected to serve as a collection value Tnow, and the environmental temperature value in the EEPROM is read to serve as a storage value Tepm.

And the air conditioner controller analyzes the acquired value Tnow of the external temperature sensor and the stored value Tepm of the environmental temperature in the EEPROM to judge whether the acquired value Tnow is greater than the stored value Tepm. If the collected value Tnow is less than or equal to the stored value Tepm, assigning the collected value Tnow to a display value Tdis, and displaying the display value Tdis on an automobile instrument; if the collected value Tnow is greater than the stored value Tepm, the following determination is continued.

And when the collected value Tnow is greater than the stored value Tepm, the air conditioner controller reads the parking time of the automobile and judges whether the automobile is in a cold automobile state or a hot automobile state according to the parking time. If the automobile parking time is less than 60min, the automobile is judged to be in a hot automobile state, the stored value Tepm is given to the display value Tdis and is displayed on an automobile instrument; and if the automobile stopping time is less than 1min or more than 60min, judging that the automobile is in a cold state, and continuing to enter the next judgment.

When the automobile is in a cold state, the air conditioner controller reads the water temperature value Tbor of the engine and judges whether the water temperature value Tbor of the engine is less than 20 ℃. If the water temperature value Twor of the engine is less than 20 ℃, giving the acquired value Tnow to a display value Tdis, and displaying the display value Tdis on an automobile instrument; and if the water temperature value Tmor of the engine is not less than 20 ℃, comparing the acquired value Tnow with the water temperature value Tmor of the engine. If the acquired value Tnow is smaller than the water temperature value Tbor of the engine, assigning the acquired value Tnow to a display value Tdis, and displaying the display value Tdis on an automobile instrument; and if the engine water temperature value Twor is smaller than the acquisition value Tnow, giving the engine water temperature value Twor to a display value Tdis, and displaying on an automobile instrument.

Through the analysis of the collection value of the external temperature sensor, the storage value of the environment in the storage and the water temperature value of the engine, the mode of displaying the effective temperature value is finally selected, the accuracy of displaying the temperature value of the vehicle instrument can be improved, and the method is favorable for providing effective environment temperature information for a driver.
