[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used herein are for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0061] See also Figure 1 , Figure 1 The flow chart of the steps S101-S103 of the vehicle-to-vehicle external temperature detection method provided in the embodiment of the present application will be combined with Figure 1 Steps S101-S103 are shown for explanation.

[0062] Step S101: After the vehicle is started, determining the start-up state of the vehicle, and determining first display data of the current outside temperature of the vehicle according to the start-up state of the vehicle; wherein the start-up state of the vehicle includes a cold start state and a hot start state;

[0063] Step S102: setting a delay time corresponding to different starting states of the vehicle;

[0064] Step S103: When it is determined that the waiting time after the first display data of the current outside temperature of the vehicle meets the delay time, adjust the first display data of the current outside temperature of the vehicle according to the first temperature detection data of the temperature sensor at the current moment.

[0065] The above-mentioned method for detecting the vehicle's outside temperature based on the vehicle determines the vehicle's starting status after the vehicle is started, and sets delay times corresponding to different starting statuses for different vehicle starting statuses. After the waiting time satisfies the delay time, the first display data of the vehicle's current outside temperature is adjusted according to the first temperature detection data of the temperature sensor at the current moment. In this way, after the vehicle is started, the first display data of the vehicle's outside temperature can be adjusted in real time according to the influence of the vehicle components in the cabin on the temperature sensor used to detect the outside temperature under different vehicle starting statuses, thereby improving the accuracy of the displayed outside temperature.

[0066] The above exemplary steps of the embodiment of the present application are described below respectively.

[0067] In step S101, after the vehicle is started, the starting state of the vehicle is determined, and first display data of the current outside temperature of the vehicle is determined according to the starting state of the vehicle; wherein the starting state of the vehicle includes a cold start state and a hot start state.

[0068] In some embodiments, after the vehicle is started, it is first necessary to determine the starting status of the vehicle, which includes a cold start status and a hot start status, and initialize the first display data of the vehicle's current outside temperature according to the cold start status and the hot start status respectively, that is, determine the initial value of the first display data of the vehicle's current outside temperature according to the cold start status and the hot start status respectively.

[0069] As an example, under normal circumstances, the operating temperature of a vehicle engine is 85 degrees to 105 degrees. If the vehicle engine is turned off, after a period of time, the engine temperature gradually cools down to below 40 degrees. If the vehicle is started at this time, the vehicle's start-up state is a cold start; if the vehicle engine is turned off, after a period of time, the engine temperature is still greater than 40 degrees, the vehicle's start-up state is a hot start. At this time, it is necessary to determine the first display data of the vehicle's current outside temperature based on the vehicle's start-up state.

[0070] In the above method, after the vehicle is started, the starting status of the vehicle is first determined, and after the starting status is determined, the first display data of the vehicle's current outside temperature is initialized according to different starting statuses, thereby obtaining a more accurate initialization value, which provides an adjustment basis for the subsequent adjustment of the first display data of the vehicle's current outside temperature.

[0071] In step S102 , for different startup states of the vehicle, delay times corresponding to the different startup states are set.

[0072] In some embodiments, different delay times can be set for cold start and hot start states respectively. The delay time is used to simulate the process in which the temperature sensor outside the vehicle interacts with the environment under different start-up states (for example, air enters the air intake grille to take away excess heat from the temperature sensor), and gradually approaches the ambient temperature.

[0073] As an example, for different startup states, the delay time can be set by counting with a counter. For example, different count values ​​are set for different startup states. After each unit time, the counter adds 1 to the count value corresponding to the current startup state. When the count value corresponding to the current startup state reaches the set count threshold, it can be determined that the delay time corresponding to the current startup state has been reached. A unit time can be any time value that is not equal to zero. For example, a unit time can be 1 second, 0.2 seconds, or 2 seconds. Typically, a unit time defaults to 1 second.

[0074] The above method simulates the process in which the outdoor temperature sensor interacts with the environment and gradually approaches the ambient temperature under different startup states by setting delay times corresponding to different startup states. After the corresponding delay time, it can be approximately considered that the first temperature detection data of the temperature sensor at the current moment is close to the current ambient temperature, laying the foundation for the subsequent adjustment of the first display data of the vehicle's current outdoor temperature.

[0075] In step S103 , when it is determined that the waiting time after the first display data of the current outside temperature of the vehicle meets the delay time, the first display data of the current outside temperature of the vehicle is adjusted according to the first temperature detection data of the temperature sensor at the current moment.

[0076] In some embodiments, after a delay time corresponding to the startup state has passed, it can be considered that the first temperature detection data of the temperature sensor at the current moment is close to the current ambient temperature, and then the first display data of the current outside temperature of the vehicle is adjusted according to the first temperature detection data of the temperature sensor at the current moment.

[0077] As an example, during the adjustment process, the first temperature detection data of the temperature sensor at the current moment can be directly used as the first display data of the current outside temperature of the vehicle, or it can be adjusted in the direction close to the first temperature detection data of the temperature sensor at the current moment. Only one fixed value is adjusted each time, and the fixed value can be flexibly set, for example: 1 degree, 0.5 degrees, 2 degrees.

[0078] In the above manner, by adjusting the first display data of the current vehicle exterior temperature, first display data of the current vehicle exterior temperature that is closer to the ambient temperature is obtained.

[0079] In some embodiments, see Figure 2 , Figure 2 This is a flow chart of steps S201-S203 provided in an embodiment of the present application. The first display data of determining the current outside temperature of the vehicle according to the startup state of the vehicle can be achieved through steps S201-S203, which will be explained in combination with each step.

[0080] In step S201 , when the vehicle is in the cold start state, first display data of the current outside temperature of the vehicle is determined according to second temperature detection data of the temperature sensor at the current moment.

[0081] In some embodiments, the second temperature detection data of the temperature sensor represents data detected by the temperature sensor when the first display data of the current outside temperature of the vehicle is determined according to the startup state of the vehicle after the startup state of the vehicle is determined.

[0082] In some embodiments, the first temperature detection data of the temperature sensor represents data detected by the temperature sensor when adjusting the first display data of the current outside temperature of the vehicle.

[0083] In some embodiments, when the vehicle is in a cold start state, since the vehicle has just been ignited, although the engine has started to work, the engine water temperature has not increased significantly and is still below 40 degrees. Therefore, the temperature sensor is hardly affected by excess heat sources. It can be considered that the second temperature detection data of the temperature sensor is relatively accurate. Therefore, the second temperature detection data of the temperature sensor at the current moment can be determined as the first display data of the current outside temperature of the vehicle.

[0084] In step S202, when the vehicle is in the hot start state and the second display data of the vehicle's outside temperature before the vehicle is turned off meets the stability condition, the first display data of the vehicle's current outside temperature is determined based on the second display data of the vehicle's outside temperature before the vehicle is turned off.

[0085] In some embodiments, the second display data of the outside temperature of the vehicle before the vehicle is turned off is also determined according to a method based on the vehicle's detection of the outside temperature of the vehicle. The second display data of the outside temperature of the vehicle before the vehicle is turned off is data adjusted by the method based on the vehicle's detection of the outside temperature of the vehicle to the first display data of the current outside temperature of the vehicle determined according to the startup state.

[0086] In some embodiments, when the vehicle is in a hot start state, since the vehicle is restarted within a short period of time after being turned off, and the engine starts working again immediately after stopping, the engine water temperature has not dropped significantly and is still in an operating state of 85 degrees to 105 degrees. In addition, since the vehicle has just started to move, almost no wind enters the air intake grille, and the temperature sensor is affected by excess heat sources. It can be considered that the second temperature detection data of the temperature sensor is inaccurate. At this time, if the difference between the second display data of the outside temperature before the vehicle is turned off and the second temperature detection data of the temperature sensor is within a stable range (for example: the absolute value of the difference is less than 10 degrees), it can be considered that the second display data of the outside temperature before the vehicle is turned off is relatively accurate, and the second display data of the outside temperature before the vehicle is turned off can be determined as the first display data of the current outside temperature of the vehicle.

[0087] In step S203, when the vehicle is in the hot start state but the second display data of the outside temperature before the vehicle is turned off does not meet the stability condition, the first display data of the current outside temperature of the vehicle is determined according to the second temperature detection data of the temperature sensor at the current moment.

[0088] In some embodiments, when the vehicle is in a hot start state, since the vehicle is restarted within a short period of time after being turned off, and the engine starts working again immediately after stopping, the engine water temperature has not dropped significantly and is still in an operating state of 85 degrees to 105 degrees. In addition, since the vehicle has just started to move, almost no wind enters the air intake grille, and the temperature sensor is affected by excess heat sources. It can be considered that the second temperature detection data of the temperature sensor is inaccurate. At this time, if the difference between the second display data of the outside temperature before the vehicle is turned off and the second temperature detection data of the temperature sensor is not within a stable range (for example, the absolute value of the difference is greater than or equal to 10 degrees), it can be considered that the second display data of the outside temperature before the vehicle is turned off is no longer accurate, and the second temperature detection data of the temperature sensor at the current moment still needs to be determined as the first display data of the current outside temperature of the vehicle.

[0089] The above method provides a specific scheme for initializing the first display data of the vehicle's current outside temperature. In the cold start state, the first display data of the vehicle's current outside temperature is determined by the second temperature detection data of the temperature sensor at the current moment; in the hot start state, based on whether the second display data of the vehicle's outside temperature before the vehicle is turned off meets the stability condition, the second display data of the vehicle's outside temperature before the vehicle is turned off or the second temperature detection data of the temperature sensor at the current moment is selected as the first display data of the vehicle's current outside temperature, thereby obtaining more accurate first display data of the vehicle's current outside temperature, which provides a basis for subsequent adjustment of the first display data of the vehicle's current outside temperature.

[0090] In some embodiments, see Figure 3, Figure 3 It is a flow chart of steps S301-S303 provided in an embodiment of the present application. The determination of the startup status of the vehicle can be achieved through steps S301-S303, which will be explained in combination with each step.

[0091] In step S301, the startup information of the vehicle is obtained.

[0092] In some embodiments, the third temperature detection data of the temperature sensor represents data detected by the temperature sensor when determining the startup state of the vehicle.

[0093] In some embodiments, the vehicle startup information includes but is not limited to third temperature detection data of the temperature sensor, the current temperature of the vehicle component, and the temperature state of the vehicle component. The current temperature of the vehicle component may be the engine water temperature, and the temperature state of the vehicle component may be the engine water temperature state.

[0094] In step S302, when the startup information of the vehicle meets the cold start state condition, the vehicle is determined to be in a cold start state; wherein, the vehicle meeting the cold start state condition includes: the temperature state of the vehicle component is normal, the third temperature detection data of the temperature sensor is less than or equal to the first temperature threshold, and the difference between the current temperature data of the vehicle component and the third temperature detection data of the temperature sensor is less than or equal to the first temperature comparison threshold; or, the temperature state of the vehicle component is normal, the third temperature detection data of the temperature sensor is greater than the first temperature threshold, and the difference between the current temperature data of the vehicle component and the third temperature detection data of the temperature sensor is less than or equal to the second temperature comparison threshold; the second temperature comparison threshold is greater than the first temperature comparison threshold.

[0095] In some embodiments, see Figure 8 , Figure 8 The first flow chart provided for the embodiment of the present application. First, read the third temperature detection data of the temperature sensor and determine whether the data is valid. If invalid, display a null value "--". Then obtain the engine water temperature and the engine water temperature status to determine whether the engine water temperature status is normal. If the engine water temperature status is normal, and the third temperature detection data of the temperature sensor is less than or equal to the first temperature threshold (20 degrees), and the difference (ΔT) between the engine water temperature and the third temperature detection data of the temperature sensor is less than or equal to the first temperature comparison threshold (2 degrees), then the vehicle is judged to be in a cold start state; if the engine water temperature status is normal, and the third temperature detection data of the temperature sensor is greater than the first temperature threshold (20 degrees), and the difference (ΔT) between the engine water temperature and the third temperature detection data of the temperature sensor is less than or equal to the second temperature comparison threshold (5 degrees), then the vehicle is also judged to be in a cold start state. In addition, the second temperature comparison threshold must be greater than the first temperature comparison threshold.

[0096] In step S303, when the startup information of the vehicle meets the hot start state condition, the vehicle is determined to be in the hot start state; wherein, the vehicle meets the cold start state condition including: the temperature state of the vehicle component is normal, the third temperature detection data of the temperature sensor is less than or equal to the first temperature threshold, and the difference between the current temperature data of the vehicle component and the third temperature detection data of the temperature sensor is greater than the first temperature comparison threshold; or, the temperature state of the vehicle component is normal, the third temperature detection data of the temperature sensor is greater than the first temperature threshold, and the difference between the current temperature data of the vehicle component and the third temperature detection data of the temperature sensor is greater than the second temperature comparison threshold; or, the temperature state of the vehicle component is abnormal.

[0097] In some embodiments, see Figure 8 If the engine water temperature is normal, the third temperature detection data of the temperature sensor is less than or equal to the first temperature threshold (20 degrees), and the difference (ΔT) between the engine water temperature and the third temperature detection data of the temperature sensor is greater than the first temperature comparison threshold (2 degrees), then the vehicle is judged to be in a hot start state; if the engine water temperature is normal, the third temperature detection data of the temperature sensor is greater than the first temperature threshold (20 degrees), and the difference (ΔT) between the engine water temperature and the third temperature detection data of the temperature sensor is greater than the second temperature comparison threshold (5 degrees), then the vehicle is also judged to be in a hot start state; or when it is judged that the engine water temperature is abnormal, the vehicle is directly judged to be in a hot start state, where the normal or abnormal engine water temperature state can be directly obtained through the vehicle bus.

[0098] The above-mentioned method provides specific determination conditions for determining the vehicle's startup state, can accurately determine the vehicle's startup state, and provides a basis for initializing the first display data of the vehicle's current outside temperature.

[0099] In some embodiments, see Figure 4 , Figure 4 This is a flow chart of steps S401-S402 provided in an embodiment of the present application. Setting the delay time corresponding to the different starting states of the vehicle can be achieved through steps S401-S402, which will be explained in combination with each step.

[0100] In step S401, when the vehicle is in the cold start state, a first delay time corresponding to the cold start state is set;

[0101] In some embodiments, a corresponding first delay time needs to be set for the cold start state. Here, the first delay time is set by the counting result of the counter meeting a condition to adjust the first display data of the current vehicle outside temperature.

[0102] For example, see Figure 10 , Figure 10 A flowchart of the cold start temperature processing process provided by an embodiment of the present application. First, the cold start count value is set to Cc, and the cold start count threshold is set to 5. The counter is used to count. Every time a unit time passes, the counter adds 1 to the cold start count value. When the cold start count value reaches the set cold start count threshold (5), it can be determined that the first delay time corresponding to the cold start state has been reached. A unit time can be any time value not equal to zero, for example: a unit time can be 1 second, 0.2 seconds, or 2 seconds. When a unit time is 1 second, the first delay time corresponding to the cold start state is 5 seconds.

[0103] In the above manner, the first delay time is set for the cold start state by counting with a counter, and since the time is not directly calculated, the delay time can be adjusted by adjusting the unit time.

[0104] In step S402, when the vehicle is in the hot start state, if the first temperature detection data of the temperature sensor is less than the first display data of the current outside temperature of the vehicle, a second delay time corresponding to the hot start state is set; if the first temperature detection data of the temperature sensor is greater than or equal to the first display data of the current outside temperature of the vehicle, a third delay time corresponding to the target speed interval is determined based on the target speed interval to which the current driving information of the vehicle belongs; wherein, the greater the speed of the speed interval, the smaller the corresponding third delay time.

[0105] In some embodiments, due to the more complex factors affecting the hot start state, a second delay time and a third delay time need to be set for the hot start state. Here, the second delay time and the third delay time are still set by the counter counting result meeting the conditions to adjust the first display data of the current vehicle outdoor temperature.

[0106] For example, see Figure 11, which is a flowchart of the hot start temperature processing flow provided by an embodiment of the present application. First, a first hot start count value C1, a second hot start count value C2, a third hot start count value C3, a fourth hot start count value C4 and a fifth hot start count value C0 are set, as well as a first hot start count threshold value (500) corresponding to the first hot start count value C1, a second hot start count threshold value (100) corresponding to the second hot start count value C2, a third hot start count threshold value (50) corresponding to the third hot start count value C3, a fourth hot start count threshold value (20) corresponding to the fourth hot start count value C4, and a fifth hot start count threshold value (10) corresponding to the fifth hot start count value C5, wherein the second hot start count value is a count value for a vehicle speed interval greater than 5 km / h and less than or equal to 50 km / h. The third hot start count value is a count value for a vehicle speed range greater than 50 km / h and less than or equal to 100 km / h, and the fourth hot start count value is a count value for a vehicle speed range greater than 100 km / h. Before counting, the first temperature detection data of the temperature sensor is first judged. If the first temperature monitoring data of the sensor temperature is less than the first display data of the current outside temperature of the vehicle, the fifth hot start count value C0 is counted. If the first temperature detection data of the sensor temperature is greater than or equal to the first display data of the current outside temperature of the vehicle, the first hot start count value C1, the second hot start count value C2, the third hot start count value C3, or the fourth hot start count value C4 is used for counting according to different vehicle speed ranges.

[0107] If the speed interval is larger, the calculation result of the counter will meet the conditions faster, so that the delay time will be shorter; similarly, the calculation result of the counter will meet the conditions slower, so that the delay time will be longer; specifically, for different speed intervals, the count value of the counter will be different each time, the larger the speed of the interval, the larger the count value, and the faster the calculation result meets the conditions, so that the delay time will be shorter; and the hot start count threshold will also decrease as the speed interval becomes larger; for example, when the speed interval is greater than 100km / h, C4 will increase by 15 each time, where 15 is the count value, and the corresponding fourth hot start count threshold is set to 20; when the speed interval is greater than 50km / h and less than or equal to 100km / h, C3 will increase by 5 each time, where 5 is the count value, and the corresponding third hot start count threshold is set to 50; when the vehicle speed range is greater than 5 km / h and less than or equal to 50 km / h, C2 is increased by 2 each time, where 2 is the count value, and the corresponding third hot start count threshold is set to 100; when it is not in the vehicle speed range, that is, when the vehicle speed is less than or equal to 5 km / h, C1 is increased by 1 each time, and C2, C3, and C4 are all reduced by 1, to simulate the state that the heat source influence on the temperature sensor begins to increase again at low speed, and it takes a longer time for the temperature sensor to be consistent with the external temperature. The first hot start count threshold is set to 500. When C1 reaches the first hot start count threshold (500), C0, C1, C2, C3, and C4 are reset to zero. Each time the count value of C1, C2, C3, and C4 is increased, a unit time is required. A unit time can be any time value not equal to zero, for example: a unit time can be 1 second, 0.2 seconds, or 2 seconds.

[0108] In the above method, a second delay time is set for the hot start state by counting with a counter, and a corresponding third delay time is set for different vehicle speed ranges according to different vehicle speed ranges, so as to simulate the process that the faster the vehicle speed, the faster the heat dissipation in the cabin, and the temperature sensor can approach the external ambient temperature faster. Moreover, since the time is not calculated directly, the delay time can be adjusted by adjusting the unit time.

[0109] In some embodiments, see Figure 5 , Figure 5 This is a flow chart of steps S501-S502 provided in an embodiment of the present application. Adjusting the first display data of the current outside temperature of the vehicle according to the first temperature detection data of the temperature sensor at the current moment can be achieved through steps S501-S502, which will be explained in combination with each step.

[0110] In step S501, when the vehicle is in the cold start state, the difference between the first temperature detection data of the temperature sensor and the first display data of the current outside temperature of the vehicle is calculated; if the difference is within a first preset interval, the first display data of the current outside temperature of the vehicle is adjusted to the first temperature detection data; if the difference is outside the first preset interval, the adjustment direction of the first display data of the current outside temperature of the vehicle is determined according to the interval segment outside the first preset interval to which the difference belongs, and the first display data of the current outside temperature of the vehicle is adjusted according to the adjustment direction with a preset step size; the adjustment direction includes an increasing direction and a decreasing direction.

[0111] For example, see Figure 10 When Cc is counted to be greater than or equal to 5, the difference between the first temperature detection data of the temperature sensor and the first display data of the current outdoor temperature of the vehicle is calculated. If the difference is within the first preset interval, the first display data of the current outdoor temperature of the vehicle is directly adjusted to the first temperature detection data of the temperature sensor. The first preset interval can be flexibly set. In the embodiment of the present application, the first preset interval is set to [-1, 1]. If it is not within this interval, it is considered that the difference is too large and the first display data of the current outdoor temperature of the vehicle needs to be adjusted. The adjustment method can be that when the first temperature detection data of the temperature sensor is greater than the first display data of the current outdoor temperature of the vehicle, the first display data of the current outdoor temperature of the vehicle is increased by a preset step size, and when the first temperature detection data of the temperature sensor is less than the first display data of the current outdoor temperature of the vehicle, the first display data of the current outdoor temperature of the vehicle is lowered by a preset step size. The preset step size here can be flexibly set. In the embodiment of the present application, the preset step size is set to 1.

[0112] Here, the reason for not directly adjusting the first display data of the vehicle's current outdoor temperature to the first temperature detection data of the temperature sensor is that when the first temperature detection data of the temperature sensor is too different from the first display data of the vehicle's current outdoor temperature (not within the first preset interval), a buffer time needs to be reserved to ensure that the first temperature detection data of the temperature sensor can be consistent with the external ambient temperature. More values ​​are not adjusted at a time, but only a preset step size is adjusted. Therefore, after the adjustment, Cc must be set to zero and the counting must be restarted.

[0113] In step S502, when the vehicle is in the hot start state, if the first temperature detection data of the temperature sensor is less than the first display data of the current outside temperature of the vehicle, and the difference between the first display data of the current outside temperature of the vehicle and the first temperature detection data of the temperature sensor is within the second preset interval, the first display data of the current outside temperature of the vehicle is adjusted in a decreasing adjustment direction with a preset step size; if the first temperature detection data of the temperature sensor is greater than or equal to the first display data of the current outside temperature of the vehicle, and the difference between the first temperature detection data of the temperature sensor and the first display data of the current outside temperature of the vehicle is within the second preset interval, the first display data of the current outside temperature of the vehicle is adjusted in an increasing adjustment direction with a preset step size.

[0114] For example, see Figure 11 After determining that the first temperature detection data of the temperature sensor is less than the first display data of the current outside temperature of the vehicle, start counting C0. When the fifth hot start count value C0 is greater than or equal to the fifth hot start count threshold value (10), it is determined that the difference between the first display data of the current outside temperature of the vehicle and the first temperature detection data of the temperature sensor is in the second preset interval [1, +∞), that is, the difference between the first display data of the current outside temperature of the vehicle and the first temperature detection data of the temperature sensor is greater than 1. The first display data of the current outside temperature of the vehicle is adjusted with a preset step size in a decreasing adjustment direction, that is, the first display data of the current outside temperature of the vehicle is reduced by 1, and then all hot start count values ​​are reset to zero, and the size relationship between the first temperature detection data of the temperature sensor and the first display data of the current outside temperature of the vehicle is determined again, and the above cycle is repeated.

[0115] After determining that the first temperature detection data of the temperature sensor is greater than or equal to the first display data of the current outside temperature of the vehicle, and determining the corresponding hot start count value according to the vehicle speed range and when the corresponding hot start count value reaches the corresponding hot start threshold, determine that the difference between the first temperature detection data of the temperature sensor and the first display data of the current outside temperature of the vehicle is in the second preset range [1, +∞), that is, the difference between the first temperature detection data of the temperature sensor and the first display data of the current outside temperature of the vehicle is greater than 1, adjust the first display data of the current outside temperature of the vehicle with a preset step size in an increasing adjustment direction, that is, add 1 to the first display data of the current outside temperature of the vehicle, then reset all the hot start count values ​​to zero, and restart the determination of the size relationship between the first temperature detection data of the temperature sensor and the first display data of the current outside temperature of the vehicle, and repeat the above cycle.

[0116] However, when the vehicle speed is not within the speed range, that is, when the vehicle speed is less than or equal to 5 km / h (too low a speed will prevent the wind from the grille from taking away excess heat in the cabin, so less than or equal to 5 km / h is not set in the speed range), it is necessary to count C1 and cumulatively subtract C2, C3, and C4. Each time C1 is increased by 1, C2, C3, and C4 are subtracted by 1. When C1 is greater than or equal to 500, all hot start count values ​​are reset to zero, and the relationship between the first temperature detection data of the temperature sensor and the first display data of the current outside temperature of the vehicle is judged again.

[0117] In some embodiments, see Figure 6 , Figure 6 This is a flow chart of steps S601-S602 provided in an embodiment of the present application. Steps S601-S602 may be further executed after determining the startup status of the vehicle, and will be described in conjunction with each step.

[0118] In step S601, the startup information of the vehicle is detected in real time.

[0119] In step S602, if it is determined that the startup state of the vehicle has changed according to the startup information detected in real time, the startup state of the vehicle is updated according to the changed startup state.

[0120] In some embodiments, the cold start state and the hot start state correspond to two start states of the vehicle respectively, but during the driving process of the vehicle, the start information for determining the start state will gradually meet the hot start state. At this time, adjusting the first display data of the current outside temperature of the vehicle based on the cold start state adjustment method is no longer applicable, and it is necessary to adjust the first display data of the current outside temperature of the vehicle based on the hot start state adjustment method. The cold start state and hot start state here do not only refer to the state at "startup", but can also be the state during driving. As long as the start information for determining the start state meets any start state, it is dynamically adjusted to the corresponding start state, and then the first display data of the current outside temperature of the vehicle is adjusted according to the corresponding start state.

[0121] For example, see Figure 9 , Figure 9 This is a second flow chart provided in accordance with an embodiment of the present application. Figure 9 The A in the flow chart represents the Figure 8A in the figure, after waiting for 0.1 seconds, obtains (reads) the first temperature detection data of the temperature sensor and the vehicle speed, and determines whether the sensor temperature is valid. Here, to determine whether the sensor temperature is valid, the working status of the sensor can be obtained according to the vehicle bus. If the working status of the sensor is normal, the sensor temperature is determined to be valid, and then it is determined whether the first display data of the current outdoor temperature of the vehicle is invalid data (such as a null value or display "--"). If the first display data of the current outdoor temperature of the vehicle is valid data and it is in a cold start state, the vehicle's startup information (engine water temperature, engine water temperature status) is obtained at this time, and the startup information is judged. If the engine water temperature is normal and the engine water temperature is greater than 50 degrees, it is determined to be a hot start state; if the engine water temperature is normal and the engine water temperature is less than or equal to 50 degrees, it is determined to be a cold start state; if the engine water temperature is abnormal (the engine water temperature is too high due to lack of water in the water tank or damage to the fan, rupture of the pipe, etc.), it is also determined to be a hot start state.

[0122] The above method detects the vehicle startup information in real time during the vehicle driving process, and can timely adjust the corresponding vehicle startup status, providing an adjustment basis for subsequently adjusting the first display data of the current outside temperature to valid data according to the vehicle startup status.

[0123] In some embodiments, see Figure 7 , Figure 7 This is a flow chart of steps S701-S703 provided in an embodiment of the present application, which will be explained in conjunction with each step.

[0124] In step S701, the working status of the temperature sensor is obtained.

[0125] In some embodiments, the vehicle may also encounter the following situations after starting: temperature sensor failure, malfunction, short circuit, signal transmission failure or other failures cause the first display data of the vehicle's current outside temperature to be invalid data. In these cases, it is necessary to use an invalid sensor temperature processing method and an invalid display temperature processing method to adjust the first display data of the vehicle's current outside temperature respectively. Here, it is necessary to first obtain the working status of the temperature sensor.

[0126] In step S702, when the working state of the temperature sensor is abnormal and a first abnormal time has passed, the first display data of the current outside temperature of the vehicle is cleared.

[0127] For example, see Figure 9 、 Figure 12 , Figure 12 This is a flowchart of the invalid sensor temperature processing provided in an embodiment of the present application. Figure 9In the case where the working state of the temperature sensor is judged to be abnormal, the invalid sensor temperature processing method is entered. The abnormality here can refer to the invalid sensor temperature. Usually, the external temperature sensor is a thermistor. If the thermistor has a short circuit or other fault, the vehicle bus will collect a fault signal. At this time, the working state of the temperature sensor is considered abnormal. Figure 12 , the preset first abnormal count value Cv is accumulated until Cv is greater than 5, and the first display data of the current outside temperature of the vehicle is set to "--".

[0128] In step S703 , when the first display data of the current outside temperature of the vehicle is empty data and after a second abnormal time has passed, the first display data of the current outside temperature of the vehicle is adjusted to the first temperature detection data of the temperature sensor.

[0129] For example, see Figure 9 、 Figure 13 , Figure 13 This is a flowchart of the invalid display temperature processing provided in an embodiment of the present application. Figure 9 In the case of judging that the displayed temperature is "--", the invalid displayed temperature processing method is entered. Figure 13 , the preset second abnormal count value Ci is accumulated until Ci is greater than 2, and the first display data of the current outdoor temperature of the vehicle is set as the first temperature detection data of the temperature sensor.

[0130] The above-mentioned method provides abnormality handling solutions for two different abnormal states, and provides a setting basis for setting the first display data of the current outside temperature of the vehicle in the abnormal state.

[0131] The vehicle-based external temperature detection method provided in the embodiment of the present application can adjust the first display data of the vehicle's external temperature in real time after the vehicle is started, based on the impact of vehicle components in the cabin on the temperature sensor used to detect the external temperature under different vehicle startup states, thereby improving the accuracy of the displayed external temperature.

[0132] Based on the same inventive concept, an embodiment of the present application also provides a device for detecting the vehicle's external temperature, which corresponds to the method for detecting the vehicle's external temperature in the above embodiment. Since the principle of solving the problem by the device in the embodiment of the present application is similar to the above method for detecting the vehicle's external temperature, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.

[0133] like Figure 14 As shown, Figure 14 FIG2 is a schematic diagram of a vehicle-to-vehicle external temperature detection device 800 according to an embodiment of the present application. The vehicle-to-vehicle external temperature detection device 800 includes:

[0137] Those skilled in the art should understand that Figure 14 The functions implemented by each unit in the vehicle-based detection device 800 for detecting vehicle-exterior temperature can be understood with reference to the aforementioned description of the vehicle-based detection method for detecting vehicle-exterior temperature. Figure 14 The functions of the various units in the vehicle-to-vehicle external temperature detection device 800 shown can be implemented by a program running on a processor, or by a specific logic circuit.

[0149] In a possible implementation, the adjusting module 803 adjusts the first display data of the current outside temperature of the vehicle according to the first temperature detection data of the temperature sensor at the current moment, including:

[0150] When the vehicle is in the cold start state, calculating the difference between the first temperature detection data of the temperature sensor and the first display data of the current outside temperature of the vehicle; if the difference is within a first preset interval, adjusting the first display data of the current outside temperature of the vehicle to the first temperature detection data; if the difference is outside the first preset interval, determining an adjustment direction of the first display data of the current outside temperature of the vehicle based on the interval segment outside the first preset interval to which the difference belongs, and adjusting the first display data of the current outside temperature of the vehicle in accordance with the adjustment direction with a preset step size; the adjustment direction includes an increasing direction and a decreasing direction;
