DETAILED DESCRIPTION
[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0048] With the continuous development of science, technology and economy, cars have become popular in many families and have become an important means of transportation in daily life. In order to ensure the safety and comfort of the vehicle, the vehicle generally collects relevant data of the vehicle operation through relevant sensor equipment during driving.
[0049] Vehicle ambient temperature is one of the important data. By collecting the vehicle ambient temperature, we can understand the external environment temperature of the vehicle in real time, which is crucial for evaluating the operating status and performance of the vehicle. Especially in extreme weather conditions (such as high temperature and low temperature environments), the operating efficiency and stability of the vehicle may be affected, so monitoring the ambient temperature helps to detect and respond to potential problems in a timely manner. For example, in a high temperature environment, the vehicle's cooling system needs to work more efficiently to maintain the normal temperature of the engine; in a low temperature environment, it is necessary to ensure that the fuel system can supply fuel normally and avoid freezing. By collecting ambient temperature data, the vehicle can be adjusted and optimized accordingly to improve its performance and stability.
[0050] Existing vehicles generally collect the vehicle's ambient temperature through ambient temperature sensors installed on the vehicle body. However, when the ambient temperature sensor malfunctions, fails, or senses abnormalities, the collected vehicle ambient temperature will be inaccurate, which will in turn cause vehicle control errors and affect the vehicle's performance.
[0051] In response to the above technical problems, the present application proposes a vehicle ambient temperature collection method, which solves the technical problem that the vehicle cannot collect accurate vehicle ambient temperature when the vehicle's ambient temperature sensor fails, fails or senses abnormalities, thereby improving the accuracy of vehicle ambient temperature collection.
[0052] The technical solution of the vehicle ambient temperature collection method provided by the present application is described in detail below through specific embodiments. It should be noted that the following embodiments can exist alone or in combination with each other, and the same or similar contents may not be repeated in different embodiments.
[0053] It should be noted that the executor of the vehicle ambient temperature collection method provided in the embodiment of the present application is a cloud platform, and correspondingly, the vehicle ambient temperature collection device is also arranged in the cloud platform.
[0054] Specifically, the cloud platform builds a platform through remote computers (a group of computers working together) that work together to provide services to users. The cloud platform combines remote hardware resources and remote software resources to form a comprehensive service platform. The cloud platform can provide accurate temperature collection services for a large number of cars.
[0055] Figure 1 A flow chart of a vehicle ambient temperature collection method provided in an embodiment of the present application is provided. Figure 1 In some embodiments, the process of the vehicle ambient temperature collection method includes the following steps:
[0056] S101, receiving the location information of the target vehicle in real time, and determining the current location of the target vehicle based on the location information; wherein the location is a location range divided based on a preset geographic accuracy.
[0057] Among them, by dividing the location range through the preset geographic accuracy range, the ground position can be divided into a grid, and each grid of the grid is a point. Then, based on the current location information of the target vehicle, the current point of the target vehicle can be determined.
[0058] Specifically, the preset geographic accuracy may be 500m*500m, 1000m*1000m, etc., which can be set in advance by the user.
[0059] Specifically, the location information of the target vehicle can be obtained through a vehicle positioning system such as a vehicle-mounted GPS positioning system or a vehicle-mounted Beidou positioning system.
[0060] S102, when the ambient temperature sensor of the target vehicle is in an abnormal working state, obtaining the first weather forecast temperature and the first temperature correction coefficient of the current location of the target vehicle; wherein the first temperature correction coefficient is used to correct the first weather forecast temperature.
[0061] If the ambient temperature sensor of the target vehicle is in an abnormal working state, it indicates that the temperature data obtained by the ambient temperature sensor of the target vehicle is unreliable, or the ambient temperature sensor can no longer provide temperature data. At this time, the first weather forecast temperature and the first temperature correction coefficient of the current location of the target vehicle are obtained, so as to obtain the ambient temperature of the current location of the target vehicle through the first weather forecast temperature and the first temperature correction coefficient.
[0062] Specifically, the temperature correction coefficient is used to correct the weather forecast temperature so that the corrected weather forecast temperature is closer to the actual ambient temperature.
[0063] Specifically, to obtain the weather forecast temperature, a temperature acquisition request can be sent to the weather forecast platform, and the location information of the target point can be carried in the request. After receiving the request, the weather forecast platform returns the weather forecast temperature at the minimum geographical accuracy of the weather forecast including the target point.
[0064] For example, if the minimum geographic accuracy of the weather forecast is 2000m*2000m, if the current location of the target vehicle is within the minimum geographic accuracy of the weather forecast, the weather forecast temperature at the minimum geographic accuracy of the weather forecast is returned. If the current location of the target vehicle is within multiple minimum geographic accuracy ranges of the weather forecast, the average of the weather forecast temperatures within the multiple minimum geographic accuracy ranges of the weather forecast can be returned.
[0065] S103: If the first temperature correction coefficient can be obtained, a first temperature prediction value is obtained based on the first weather forecast temperature and the first temperature correction coefficient, and the first temperature prediction value is used as the ambient temperature of the target vehicle at the current location.
[0066] Among them, if the first temperature correction coefficient at the current location of the target vehicle can be obtained, the first weather forecast temperature is corrected by the first temperature correction coefficient to obtain the first temperature prediction value, and the first temperature prediction value is used as the ambient temperature of the target vehicle at the current location.
[0067] Specifically, A=Kn*B, where A represents the temperature measurement value, Kn represents the temperature correction coefficient, and B represents the weather forecast temperature.
[0068] In this embodiment, when the ambient temperature sensor of the target vehicle fails, fails, or senses abnormality, the weather forecast temperature is corrected using the temperature correction coefficient to provide a more accurate temperature prediction value as the vehicle ambient temperature of the target vehicle, thereby improving the accuracy of vehicle ambient temperature collection and helping the target vehicle to obtain more accurate vehicle ambient temperature information when the ambient temperature sensor is operating abnormally.
[0069] exist Figure 1 Based on the embodiment shown, the following Figure 2 , the technical solution of the above-mentioned vehicle ambient temperature collection method is further introduced.
[0070] Figure 2 A flow chart of another vehicle ambient temperature collection method provided in an embodiment of the present application is shown in FIG. Figure 2 In some embodiments, the process of the vehicle ambient temperature collection method includes the following steps:
[0071] S201, receiving the position information of the target vehicle in real time, and determining the current position of the target vehicle based on the position information.
[0072] Preferably, before collecting the ambient temperature, it is necessary to first determine whether the ambient temperature sensor of the target vehicle is in a normal working state.
[0073] Specifically, when the target vehicle is in a cold start phase, the method for determining whether the ambient temperature sensor of the target vehicle is in a normal working state specifically includes:
[0074] Step 1: During the cold start process of the target vehicle, determine whether a normal working network signal sent by the ambient temperature sensor can be received within the maximum threshold time range of the cold start.
[0075] Among them, the vehicle self-check is usually performed during the cold start phase of the vehicle. Therefore, during the cold start phase of the vehicle, the vehicle can determine whether the ambient temperature sensor is in a normal working state based on the network signal sent by the ambient temperature sensor.
[0076] Specifically, a vehicle cold start refers to starting the engine after it has not been running for a long time (such as after being parked at night) and the water temperature is low.
[0077] Specifically, the normal working network signal can be received by the CAN / LIN transceiver module of the target vehicle.
[0078] Step 2: If a normal working network signal sent by the ambient temperature sensor is received within the maximum threshold time range of the cold start, it is determined that the ambient temperature sensor is in a normal working state.
[0079] Step 3: If the normal working network signal sent by the ambient temperature sensor is not received within the maximum threshold time range of the cold start, it is determined that the ambient temperature sensor is in an abnormal working state.
[0080] Specifically, when the target vehicle is in the driving stage, the method for determining whether the ambient temperature sensor of the target vehicle is in a normal working state specifically includes:
[0081] Step 1: During the driving process of the target vehicle at the current location, determine whether the ambient temperature sensor sends a first temperature measurement value at a preset frequency, and determine whether the deviation between the first temperature measurement value and the first temperature prediction value is within a preset temperature range.
[0082] Among them, in addition to the vehicle startup process, during the driving process of the target vehicle, it is also necessary to determine whether the ambient temperature sensor of the target vehicle is working normally. At this time, it is possible to determine whether there is an abnormality in the ambient temperature sensor by determining whether the ambient temperature sensor sends the temperature measurement value on time and whether the temperature measurement value collected by the ambient temperature sensor is abnormal.
[0083] Specifically, under normal circumstances, the ambient temperature sensor will send the temperature measurement value it collects at a preset frequency. If the temperature measurement value sent by the ambient temperature sensor is not received, it indicates that the ambient temperature sensor is abnormal.
[0084] Specifically, since the temperature prediction value is obtained through the weather forecast temperature and the temperature correction coefficient, under normal circumstances, the temperature prediction value is likely to be inconsistent with the temperature measurement value collected by the ambient temperature sensor, but the deviation between the two will not be too large. The temperature measurement value collected by the ambient temperature sensor and the temperature prediction value should be within a certain deviation range. If the deviation between the temperature measurement value and the temperature prediction value is too large, it indicates that the ambient temperature sensor is abnormal.
[0085] Step 2: If the ambient temperature sensor sends a first temperature measurement value at a preset frequency, and a deviation between the first temperature measurement value and the first temperature prediction value is within a preset temperature range, it is determined that the ambient temperature sensor is in a normal working state.
[0086] Step 3: If the ambient temperature sensor does not send the first temperature measurement value at a preset frequency, or the deviation between the first temperature measurement value and the first temperature prediction value is outside a preset temperature range, it is determined that the ambient temperature sensor is in an abnormal working state.
[0087] S202, when the ambient temperature sensor of the target vehicle is in an abnormal working state, obtaining the first weather forecast temperature and the first temperature correction coefficient of the current location of the target vehicle; wherein the first temperature correction coefficient is used to correct the first weather forecast temperature.
[0088] S203: If the first temperature correction coefficient can be obtained, a first temperature prediction value is obtained based on the first weather forecast temperature and the first temperature correction coefficient, and the first temperature prediction value is used as the ambient temperature of the target vehicle at the current location.
[0089] S204: If the first temperature correction coefficient cannot be obtained, obtain the second temperature correction coefficient of other points closest to the current point where the target vehicle is located.
[0090] Among them, if the first temperature correction coefficient of the current location of the target vehicle cannot be obtained, the second temperature correction coefficient of other points closest to the current location of the target vehicle is obtained. This is because the ambient temperature of other adjacent points is generally not much different from the ambient temperature of the current location, so the second temperature correction coefficient of other adjacent points can be used to correct the first weather forecast temperature, and the second temperature prediction value is obtained as the ambient temperature of the target vehicle at the current location.
[0091] S205: If the second temperature correction coefficient can be obtained, a second temperature prediction value is obtained based on the first weather forecast temperature and the second temperature correction coefficient, and the second temperature prediction value is used as the ambient temperature of the target vehicle at the current location.
[0092] The first weather forecast temperature is corrected using a second temperature correction coefficient to obtain a second temperature prediction value, and the second temperature prediction value is used as the ambient temperature of the target vehicle at the current location.
[0093] S206: If the second temperature correction coefficient cannot be obtained, the first weather forecast temperature is used as the ambient temperature of the target vehicle at the current location.
[0094] If the second temperature correction coefficient of other points closest to the current location of the target vehicle cannot be obtained, the weather forecast temperature is directly used as the ambient temperature of the current location of the target vehicle.
[0095] S207, when the ambient temperature sensor of the target vehicle is in a normal working state, taking a first temperature measurement value collected by the ambient temperature sensor at the current location as the ambient temperature of the target vehicle at the current location.
[0096] If the ambient temperature sensor of the target vehicle is in a normal working state, the temperature measurement value collected by the ambient temperature sensor is directly used as the ambient temperature of the target vehicle at the current location.
[0097] S208: Generate a driving trajectory of the target vehicle based on the position information of the target vehicle during driving.
[0098] Among them, in addition to using the temperature correction coefficient to correct the weather forecast temperature when its ambient temperature sensor is abnormal, the target vehicle can also generate the temperature correction coefficient itself as a data acquisition unit. First, the target vehicle's location information during driving is required, and based on this location information, the target vehicle's driving trajectory is generated.
[0099] S209: split the driving trajectory to obtain multiple points where the driving trajectory is located.
[0100] Among them, by splitting the driving trajectory of the vehicle position according to the preset geographic accuracy range, multiple points can be obtained.
[0101] S210, obtaining a second weather forecast temperature corresponding to each point on the driving trajectory and a second temperature measurement value collected by the ambient temperature sensor.
[0102] The driving trajectory will pass through multiple points, and the weather forecast temperature at each point and the temperature measurement value collected by the ambient temperature sensor at each point will be obtained respectively.
[0103] S211, based on the data relationship between the second weather forecast temperature and the second temperature measurement value, determine a third temperature correction coefficient corresponding to each point on the driving trajectory.
[0104] Among them, for the points passed by the driving trajectory of these locations, the second temperature measurement value collected by the ambient temperature sensor at that time is compared with the second weather forecast temperature to obtain the deviation between the two, and the third temperature correction coefficient is obtained according to the deviation.
[0105] Specifically, data curve fitting or other algorithmic forms may be used to calculate the corresponding relationship between the temperature measurement value and the weather forecast temperature, thereby obtaining the temperature correction coefficient.
[0106] Specifically, A=Kn*B, where A represents the temperature measurement value, Kn represents the temperature correction coefficient, and B represents the weather forecast temperature.
[0107] Preferably, since the target vehicle can be used as a temperature correction coefficient collection unit, other vehicles can also be used. In this way, there may be multiple temperature correction coefficients at one point. Then, these temperature correction coefficients need to be processed to obtain the temperature correction coefficient of this point. In this way, the first temperature prediction value is obtained based on the following method:
[0108] Step 1, obtaining the fourth temperature correction coefficients of multiple other vehicles at the current location of the target vehicle.
[0109] When other vehicles pass the target point, they will also be used as data collection vehicles to generate the corresponding fourth temperature correction coefficient, so that the target point will have the fourth temperature correction coefficients of multiple other vehicles.
[0110] Step 2: Determine the first temperature correction coefficient of the current location of the target vehicle based on the multiple fourth temperature correction coefficients.
[0111] The first temperature correction coefficient of the target point is obtained by performing data processing on the fourth temperature correction coefficients.
[0112] Specifically, the first temperature correction coefficient may be obtained by calculating an average of a plurality of fourth temperature correction coefficients or by using a data processing method such as weighted average based on vehicle count.
[0113] Correspondingly, if there is no fourth temperature correction coefficient collected by other vehicles at this point, the target vehicle cannot obtain the first temperature correction coefficient of this point when the ambient temperature sensor is abnormal.
[0114] In this embodiment, by using different temperature collection methods in different situations, the vehicle can collect accurate vehicle ambient temperature in different situations.

[0136] If the ambient temperature sensor does not send the first temperature measurement value at a preset frequency during driving of the target vehicle at the current location, or the deviation between the first temperature measurement value and the first temperature prediction value is outside the preset temperature range, it is determined that the ambient temperature sensor is in an abnormal working state.
