Description

Technical Field

[0001] The present invention belongs to the field of automobile technology, and in particular relates to a control method, system, device and storage medium for displaying vehicle exterior temperature. Background Art

[0002] During normal use of the vehicle, in addition to the outside temperature value presented to the user, some on-board controllers including the vehicle's air-conditioning controller and engine control unit need to know the vehicle's external ambient temperature in real time to complete some normal functions of their own control. This outside temperature not only includes the outdoor open-air environment where the vehicle is driving, but also includes garages, tunnels, underground parking lots, environmental warehouse laboratories and other environments where the vehicle is stationary or driving at a low speed and which are prone to temperature differences with the outdoors, that is, the actual outdoor environment where the vehicle and its passengers are currently located.

[0003] Most vehicles are equipped with external temperature sensors to collect the temperature of the vehicle's surrounding environment, but the external temperature sensors are mostly arranged at the front grille of the vehicle. When the vehicle is at low speed, idling or just turned off, it is easily affected by the heat radiation from the engine compartment, causing the external temperature collection value to be higher than the actual external environment. Therefore, the external temperature processing algorithm should also take into account solving such problems as the temperature value collected by the sensor does not match the actual outside temperature.

[0004] There are two common methods for collecting values ​​from external temperature sensors in existing vehicles: no processing or processing. No processing means using and displaying the values ​​collected by the sensor. This method is simple and convenient, but it is prone to false alarms. For example, in summer, when the cabin temperature of an idling vehicle is too high, it is easy for the value collected by the external temperature sensor to be higher than 50°C. On the other hand, processing the external temperature value through an algorithm is a common practice for most vehicles, but the methods are different, including considerations of engine water temperature, vehicle speed, timing at a certain speed, external temperature calculation assignment, etc., or different parameter ranges, different logical timing, or different assignment methods. Summary of the invention

[0005] The present invention aims to solve the problem of how to process the collected temperature of the external temperature sensor equipped by the vehicle under common working conditions and some special working conditions to ensure that the external temperature value used by the vehicle display and related controllers can fit the actual external temperature of the vehicle, thereby providing a control method, system, device and storage medium for the vehicle external temperature display, which effectively avoids the problem of inaccurate external temperature under special working conditions, and has been verified in the mass market of mass-produced models with effective results.

[0006] The present invention is achieved through the following technical solutions:

[0007] In a first aspect, the present invention provides a method for controlling the display of vehicle external temperature, which specifically comprises the following steps:

[0008] Step 1: Determine the state of the vehicle ignition switch. If the vehicle ignition state is switched from 0FF to ON, proceed to step 2; if the vehicle ignition state is ON, proceed to step 4. If the vehicle ignition state is 0FF, the vehicle outside temperature display value at the last power-off is used as the vehicle outside temperature display value.

[0009] Step 2: Determine whether the temperature value collected by the external temperature sensor is within the normal range. If the temperature value is within the normal range, proceed to step 3;

[0010] Step 3: Determine the engine water temperature. If the engine water temperature is less than or equal to the temperature setting value, the external temperature sensor collects the current temperature value and sends the collected current temperature value to the air conditioning controller, which displays the collected current temperature value as the vehicle external temperature display value.

[0011] If the engine water temperature is greater than the temperature setting value, proceed to step 4;

[0012] Step 4: Determine the vehicle speed. If the vehicle speed is less than or equal to the speed limit, the current temperature value collected in step 3 is used as the outdoor temperature display value; if the vehicle speed is greater than the speed limit, the real-time temperature value collected by the outdoor temperature sensor is used as the outdoor temperature display value.

[0013] Furthermore, in step 2, if the temperature value is not within the normal range, it is determined to be an abnormal outside temperature value, and the air conditioning controller reports an error.

[0014] Furthermore, in step 2, the normal range is between -60°C and +120°C.

[0015] Furthermore, in step three, the temperature setting value is 50°C.

[0016] Furthermore, in step 4, the speed limit value is 10 km / h.

[0017] Furthermore, in step 4, the vehicle speed is collected every 60 seconds.

[0018] In a second aspect, the present invention further provides a control system for displaying the vehicle's external temperature, which is used to implement the control method for displaying the vehicle's external temperature in the first aspect, comprising:

[0019] Automobile ignition switch status judgment module, used to judge the status of the automobile ignition switch;

[0020] The temperature value judgment module is used to judge whether the temperature value collected by the external temperature sensor is within the normal range;

[0021] The engine water temperature judgment module is used to judge the relationship between the engine water temperature and the temperature setting value;

[0022] The vehicle speed determination module is used to determine the relationship between the vehicle speed and the speed limit value.

[0023] In a third aspect, the present invention further provides a computer device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, a method for controlling the vehicle exterior temperature display as described in any one of the present invention is implemented.

[0024] In a fourth aspect, the present invention further provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements a method for controlling the display of the vehicle exterior temperature as described in any one of the present inventions.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0035] Example 1

[0036] like Figure 1 As shown, this embodiment provides a method for controlling the display of vehicle external temperature, which specifically includes the following steps:

[0037] Step 1: Determine the state of the vehicle ignition switch. If the vehicle ignition state is switched from 0FF to ON, proceed to step 2; if the vehicle ignition state is ON, proceed to step 4. If the vehicle ignition state is 0FF, the vehicle outside temperature display value at the last power-off is used as the vehicle outside temperature display value.

[0038] Step 2: Determine whether the temperature value collected by the external temperature sensor is within the normal range. If the temperature value is within the normal range, proceed to step 3;

[0039] If the temperature value is not within the normal range, it is judged as an abnormal outside temperature value and the air conditioning controller reports an error.

[0040] The normal range is between -60℃ and +120℃.

[0041] Step 3: Determine the engine water temperature. If the engine water temperature is less than or equal to the temperature setting value, the external temperature sensor collects the current temperature value and sends the collected current temperature value to the air conditioning controller, which displays the collected current temperature value as the vehicle external temperature display value.

[0042] In this embodiment, the temperature setting value is 50°C;

[0043] If the engine water temperature is greater than the temperature setting value, proceed to step 4;

[0044] Step 4: Determine the vehicle speed. If the vehicle speed is less than or equal to the speed limit, the current temperature value collected in step 3 is used as the outside temperature display value; if the vehicle speed is greater than the speed limit, the real-time temperature value collected by the outside temperature sensor is used as the outside temperature display value;

[0045] In this embodiment, the vehicle speed limit value is 10 km / h.

[0046] The vehicle speed is collected every 60 seconds.

[0047] The following embodiment takes the process of a vehicle driving out of an underground garage in summer at an ambient temperature of 28° C. as an example to illustrate the specific control method of the present invention. The specific steps are as follows:

[0048] When the vehicle is started from a long-term stationary state, the engine water temperature is less than 50°C, and the external temperature sensor collects the current temperature value. Since the vehicle is driven out of the underground garage, the initial external temperature must be less than 28°C. At this time, the collected sensor temperature value is directly sent to the air conditioning controller. At this time, the current value of the vehicle's external temperature is the temperature collection value;

[0049] When the vehicle just starts to drive, the engine water temperature is low and there is no speed limit. At this time, the current value of the outside temperature rises rapidly as the vehicle drives out of the underground garage. Since the water temperature is low and there is no speed limit at this time, the current value of the outside temperature is still used as the outside temperature display value;

[0050] When the vehicle is driving, the engine water temperature rises rapidly to 50℃. If the vehicle speed is less than 10km / h due to traffic jams or other conditions, the external temperature collection value will be affected by thermal radiation and will be much higher than the current actual ambient temperature. The external temperature display value will not be updated at this time, that is, the current display value is the current value of the external temperature in the previous stage, which will be slightly lower than the current ambient temperature.

[0051] If the vehicle is driving on a normal road and the speed is higher than the limit value, i.e. 10km / h, then the real-time collected value of the outside temperature is equal to the ambient temperature of 8°C, and the displayed value will gradually rise to the current real-time collected ambient temperature;

[0052] When the vehicle is finished driving, it returns to the underground parking lot. The current outside temperature value should be the outside temperature display value before parking, which is 28°C. If the user returns to the vehicle within a short time, the engine water temperature is greater than 50°C, and the outside temperature sensor is affected by the vehicle's thermal radiation and the actual collected temperature is greater than 28°C, but the vehicle's outside temperature display is not updated at this time and remains at 28°C. If the user returns after a long time, the engine water temperature is less than 50°C, and the vehicle's outside temperature display is displayed according to the actual collected value of the current sensor.

[0053] Example 2

[0054] like Figure 2 As shown, this embodiment provides a control system for displaying the outside temperature of a vehicle, which is used to implement the control method for displaying the outside temperature of a vehicle described in the first aspect, including:

[0055] Automobile ignition switch status judgment module, used to judge the status of the automobile ignition switch;

[0056] The temperature value judgment module is used to judge whether the temperature value collected by the external temperature sensor is within the normal range;

[0057] The engine water temperature judgment module is used to judge the relationship between the engine water temperature and the temperature setting value;

[0058] The vehicle speed determination module is used to determine the relationship between the vehicle speed and the speed limit value.
