[0058] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0059] First, the terms involved in the embodiments of the present invention are explained:

[0060] RR interval: refers to the time interval between two adjacent R waves (ventricular depolarization waves) on the electrocardiogram. It represents the time required for the ventricles to depolarize from one time to the next, that is, a complete cardiac cycle. The length of the RR interval directly reflects the speed of the heart rate (HR).

[0061] Heart Rate Variability (HRV): refers to the difference or fluctuation in the heart's beating frequency (or heart rate) within a certain period of time.

[0062] In the related art, the door opening warning method is mostly based on the distance from the vehicle, and a fixed distance range is set. For example, when the distance is 15 meters from the rear of the vehicle, a warning is issued when the moving object enters the preset distance range. However, in this method, the distance range setting is fixed, and the current traffic conditions are diverse and complex. Only using a fixed distance range for door opening warning will result in inaccurate timing of door opening warning.

[0063] In view of this, an embodiment of the present invention provides a vehicle door opening warning method, which takes into account the different traffic conditions on the driver's side and the co-driver's side, and sets warning parameters that can represent the correspondence between the speed of the moving object and the warning range. Then, based on the relative position between the moving object and the vehicle, a warning range that can better match the current moving object can be dynamically selected, and a door opening warning is performed based on the warning range, rather than setting a fixed warning range, thereby improving the accuracy of the door opening warning.

[0064] First, how to obtain the door opening warning parameters is described. The execution subject of this embodiment may be an electronic device with processing capabilities, such as a computer, a server, etc., and the present invention is not limited here. Figure 1 This is a flow chart of a vehicle door opening warning method provided by an embodiment of the present invention. Figure 1 As shown, the method includes:

[0065] S101 . Acquire test data for each relative position between the moving object to be tested and the vehicle to be tested.

[0066] The above test data indicates the timing evaluation data, safety evaluation data and heart rate variability data of the door opening warning at multiple distances to be tested and speeds to be tested. Among them, the moving object to be tested can be a car, an electric car, an electric car, a motorcycle and other objects that can move and control the moving speed, and the present invention is not limited here. It should be noted that the present invention does not limit the type of vehicle to be tested. The above distance to be tested indicates the distance between the moving object to be tested and the vehicle to be tested, and the moving distance to be tested can indicate the distance of the door opening warning. The above speed to be tested indicates the moving speed of the moving object to be tested.

[0067] The relative position between the moving object to be tested and the vehicle to be tested indicates the relative position of the moving object to be tested based on the vehicle to be tested. In other words, it can reflect the position of the moving object to be tested. For example, the moving object to be tested may be located on the main driving side of the vehicle to be tested, or on the passenger side of the vehicle to be tested.

[0068] It should be noted that the settings of the distance to be tested and the speed to be tested for the driver's side can be different from those for the passenger side to reflect the different traffic conditions on the driver's side and the passenger side. It should be understood that the driver's side and the passenger side may face different traffic environments and risks when the vehicle is parked. For example, the driver's side may be closer to the center line of the road or a lane with heavy traffic, while the passenger side may be closer to the roadside or a parking space. Therefore, different distances to be tested and speeds to be tested are set according to the different conditions on both sides to simulate traffic conditions at different relative positions.

[0069] The above-mentioned test personnel refer to the personnel who conduct the door opening warning test experiment inside the vehicle to be tested. Exemplarily, in a test process, the moving object to be tested travels at a preset test speed at a preset test distance from the vehicle to be tested. At the same time, the test personnel opens the door and gets off the vehicle at the preset test position of the vehicle to be tested. When the door is opened, a door opening warning is triggered. Each test can start with the warning sound and end with the moving object to be tested passing the vehicle to be tested. During the test, a portable electrocardiograph is used to detect the heart rate data of the test personnel. After each test, the test personnel evaluates the timing of the door opening warning and the safety of opening the door and getting off the vehicle at this time to obtain the above-mentioned test data.

[0070] The above-mentioned timing evaluation data represents the tester's evaluation data on the timing of the door opening warning. In other words, the timing evaluation data can be used to indicate the appropriateness of the timing of the door opening warning. For example, it can be represented by -4 to 4, where -4 represents that the door opening warning is reminded too early, 0 represents that the timing of the door opening warning is just right, and 4 represents that the door opening warning is reminded too late.

[0071] The above safety evaluation data represent the tester's evaluation data on the safety of opening the door and getting off the vehicle after the warning, for example, it can be represented by 1 to 9, where 1 represents very unsafe, 5 represents average, and 9 represents very safe.

[0072] The above-mentioned heart rate variability data indicates the degree of change between the heart rate data of the test person when he opens the door and gets off the car after the warning and the reference heart rate data. Among them, the heart rate variability data can be determined by analyzing the time domain parameters or frequency domain parameters of the heart rate data of the test person when he opens the door and gets off the car after the warning and the reference heart rate data. For example, the heart rate variability data can be represented by time domain parameters such as the standard deviation of the normal sinus RR interval and the root mean square difference (RMSSD) of the adjacent RR intervals, or by frequency domain parameters such as high frequency power (HF, 0.15~0.4Hz), low frequency power (LF, 0.04~0.15Hz), and the ratio of low frequency power to high frequency power (LF / HF). It can also be represented by nonlinear dynamic parameters such as Poincare map parameters and Lyapunov exponents to represent the heart rate variability data, or the aforementioned parameters are combined to represent the heart rate variability data, which is not limited in the embodiment of the present invention.

[0073] In some possible implementations, the electronic device may communicate with other electronic devices to obtain the test data; the test data may also be extracted from a database; or the test data may be received from an external device, such as a USB flash drive, etc. For example, Table 1 is a schematic diagram of test data provided in an embodiment of the present invention.

[0074] Table 1 Test data

[0075]

[0076] S102: Determine a sample distance between the moving object to be measured and the vehicle to be measured corresponding to each speed to be measured according to the distance to be measured, the timing evaluation data, the safety evaluation data, and the heart rate variability data.

[0077] Exemplarily, the above sample distance represents the warning distance for starting the door opening warning at the speed to be tested. As mentioned above, the moving object to be tested travels at the speed to be tested at the distance to be tested, and at the same time, the tester gets out of the car and triggers the door opening warning. Therefore, the electronic device can determine the sample distance at the speed to be tested from multiple distances to be tested based on the timing evaluation data, the safety evaluation data, and the heart rate variability data. Optionally, the electronic device can determine multiple levels of sample distances at the speed to be tested from multiple distances to be tested based on the timing evaluation data, the safety evaluation data, and the heart rate variability data, and each level of sample distance can reflect a different warning range.

[0078] In some possible implementations, for each speed to be measured, multiple distances to be measured at the speed to be measured are screened according to the optimal value in the timing evaluation data corresponding to the speed to be measured, so as to obtain a first initial distance at the speed to be measured; the first initial distance at the speed to be measured is screened according to the optimal value in the safety evaluation data corresponding to the first initial distance at the speed to be measured, so as to obtain a second initial distance at the speed to be measured; the second initial distance at the speed to be measured is screened according to the heart rate variability data corresponding to the second initial distance at the speed to be measured, so as to obtain a sample distance corresponding to the speed to be measured; wherein the sample distance indicates a first-level warning range at the speed to be measured.

[0079] Exemplarily, referring to Table 1, the electronic device can determine the optimal value of the timing evaluation data from all the timing evaluation data corresponding to speed 1 in the test data on the main driver's side, and then can use the distance to be measured corresponding to the optimal value of the timing evaluation data as the first initial distance; then, for the test data corresponding to the first initial distance, determine the optimal value of the safety evaluation data, and use the first initial distance corresponding to the optimal value of the safety evaluation data as the second initial distance; finally, for the test data corresponding to the second initial distance, determine the target heart rate variability data with the smallest heart rate fluctuation represented by the heart rate variability data, and use the second initial distance corresponding to the target heart rate variability data as the sample distance. Among them, the optimal value of the timing evaluation data can be, for example, data with a smaller absolute value, the optimal value of the safety evaluation data can be, for example, data with the largest numerical value, and the target heart rate variability data can be, for example, data with the smallest difference from the baseline heart rate data.

[0080] For example, the test speed is 40km / h, and the test distances (first initial distances) at which the timing evaluation data is the optimal value of 0 are 25m, 30m, and 35m. The safety evaluation data of 25m is 7, and the safety evaluation data of 30m and 35m are 8. The optimal value of the safety evaluation data is determined to be 8. The test distances of 30m and 35m are the second initial distances. Among the heart rate variability data of the test distances of 30m and 35m, the heart rate variability data of the test distance of 30m is smaller. Therefore, 30m is selected as the sample distance at 40km / h.

[0081] In this way, the electronic device can perform multi-layer screening on the distance to be tested corresponding to the speed to be tested according to the timing evaluation data, safety evaluation data and heart rate variability data, and obtain the sample distance with the best warning timing, the best safety and the smallest heart rate fluctuation of the tester. The sample distance can reflect the first-level warning range at the speed to be tested when the moving object is located on the main driver's side. The first warning range can be less than or equal to the sample distance, for example. The first-level warning range indicates that within the warning range, it is safe for the user to open the door and get off the car. Similarly, the sample distances at each speed to be tested when the moving object is located on the passenger side can be obtained.

[0082] In some possible implementations, for each speed to be measured, multiple distances to be measured at the speed to be measured are screened according to the heart rate variability data corresponding to the speed to be measured, so as to obtain a third initial distance at the speed to be measured; according to the worst value in the safety evaluation data corresponding to the third initial distance at the speed to be measured, the third initial distance at the speed to be measured is screened to obtain a fourth initial distance at the speed to be measured; according to the worst value in the timing evaluation data corresponding to the fourth initial distance at the speed to be measured, the fourth initial distance at the speed to be measured is screened to obtain a sample distance corresponding to the speed to be measured; wherein the sample distance indicates the second-level warning range at the speed to be measured.

[0083] Exemplarily, referring to Table 1, the electronic device can determine the target heart rate variability data with the largest heart rate fluctuation represented by the heart rate variability data from all the heart rate variability data corresponding to speed 1 in the test data on the main driver's side, for example, the data in which SDNN, RMSSD, and HF are significantly reduced, and LF and LF / HF are significantly increased in the heart rate variability data, and then the distance to be tested corresponding to the target heart rate variability data can be used as the third initial distance; then, for the test data corresponding to the third initial distance, the worst value of the safety evaluation data is determined, and the third initial distance corresponding to the worst value of the safety evaluation data is used as the fourth initial distance; finally, for the test data corresponding to the fourth initial distance, the worst value of the opportunity evaluation data is determined, and the fourth initial distance corresponding to the worst value of the opportunity evaluation data is used as the sample distance. Among them, the worst value of the opportunity evaluation data can be, for example, data with a larger absolute value, and the worst value of the safety evaluation data can be, for example, data with a smallest value.

[0084] For example, the speed to be measured is 40km / h, and the distance to be measured (the third initial distance) corresponding to the target heart rate variability data that meets the conditions at the speed to be measured is 5m, 10m, and 15m, among which the safety evaluation data corresponding to the third initial distances 5m and 10m is 2, and the safety evaluation data corresponding to the third initial distance 15m is 3. Therefore, the worst value of the safety evaluation data can be determined as 2, and the third initial distances 5m and 10m are the fourth initial distances; the timing evaluation data of the fourth initial distance 5m is 4, and the timing evaluation data of 10m is 3, so 5m is selected as the sample distance at 40km / h.

[0085] In this way, the electronic device can perform multi-layer screening on the distance to be tested corresponding to the speed to be tested according to the timing evaluation data, safety evaluation data and heart rate variability data, and obtain the sample distance with the largest heart rate fluctuation, the worst safety and the worst warning timing of the tester. The sample distance can reflect the second-level warning range at the speed to be tested when the moving object is located on the main driver's side. The second warning range can be less than or equal to the sample distance, for example. The second-level warning range indicates that within the warning range, it is unsafe for the user to open the door and get off the car. Similarly, the sample distances at each speed to be tested when the moving object is located on the passenger side can be obtained.

[0086] S103: fitting the door opening warning parameter information at each relative position according to the sample distance corresponding to each speed to be measured.

[0087] Exemplarily, as mentioned above, for each relative position, the corresponding sample distances at multiple speeds to be measured are obtained, so the corresponding relationship between the speed to be measured and the sample distance can be fitted to obtain the door opening warning parameter information at the relative position, and the sample distance represents the warning distance for starting the door opening warning. In other words, the door opening warning parameter information at the relative position indicates the corresponding relationship between the speed and the warning distance at the relative position. It should be noted that the embodiment of the present invention does not limit the fitting method, for example, it can be linear fitting or nonlinear fitting.

[0088] Optionally, the door opening warning parameter information of each relative position may include at least one level of door opening warning parameters, and each level of door opening warning parameters may represent the warning range of that level. Taking two levels of door opening warning parameters as an example, the first level of door opening warning parameters on the driver's side may be expressed as S1=k1•v+a, where S1 is the warning distance, v is the speed of the moving object (km / h), that is, the speed to be measured, k1 is a coefficient, and a is a constant. The second level of door opening warning parameters on the driver's side may be expressed as S2=k2•v+b, where S2 is the warning distance, v is the speed of the moving object (km / h), that is, the speed to be measured, k2 is a coefficient, and b is a constant.

[0089] For example, the first-level door opening warning parameter on the driver's side is expressed as S1=0.368v+11.773. When the moving object is at a speed of 20km / h and 19.133m away from the vehicle, the first-level door opening warning is started for the passengers in the vehicle. The second-level door opening warning parameter on the driver's side is expressed as S2=0.151v-0.873. When the moving object is at a speed of 20km / h and 2.147m away from the vehicle, the second-level door opening warning is started for the passengers in the vehicle.

[0090] The vehicle door opening warning method provided by the embodiment of the present invention uses test data including timing evaluation data, safety evaluation data and heart rate variability data to screen the distance to be tested for each relative position between the moving object to be tested and the vehicle to be tested, and obtains a sample distance that can reflect the warning distance for starting the door opening warning at each speed to be tested, and then can fit the door opening warning parameter information that can reflect the relationship between the speed to be tested and the sample distance according to the speed to be tested and the sample distance. In this way, more accurate door opening warning parameter information can be obtained based on the timing evaluation data, safety evaluation data and heart rate variability data, thereby improving the accuracy of subsequent door opening warnings.

[0091] The following will explain how to perform a vehicle door opening warning based on the door opening warning parameters. The execution subject of this embodiment can be a body controller, or other controllers, electronic control units or domain controllers on the vehicle. The present invention is not limited here. The following embodiments are illustrated by taking the execution subject as a body controller as an example. Figure 2 This is a flow chart of a vehicle door opening warning method provided by an embodiment of the present invention. Figure 2 As shown, the method includes:

[0092] S201. When the target vehicle is stationary, obtain speed information of the moving object, distance information between the moving object and the target vehicle, and relative position information between the moving object and the target vehicle.

[0093] Exemplarily, the target vehicle indicates a vehicle for which a door opening warning is to be issued. The speed information of the moving object indicates the moving speed of the moving object; the distance information between the moving object and the target vehicle may be, for example, the distance between the moving object and the rear of the target vehicle; the relative position information between the moving object and the target vehicle may indicate the position information of the moving object, for example, whether the moving object is on the main driving side or the co-driving side of the target vehicle. It should be noted that the embodiments of the present invention do not limit the types of the moving object and the target vehicle.

[0094] In some possible implementations, the vehicle body controller may determine whether the target vehicle is stationary based on the speed sensor or positioning information of the target vehicle. For example, when the speed value of the speed sensor is 0, the target vehicle is determined to be stationary; when the positioning information does not change within a period of time, the target vehicle is determined to be stationary.

[0095] In some possible implementations, the vehicle body controller may obtain the speed information, distance information, and relative position information of the moving object through a sensor of the target vehicle. The sensor may be, for example, a millimeter wave radar, a laser radar, a camera, etc., which is not limited in the embodiment of the present invention.

[0096] Optionally, when the target vehicle is stationary, the body controller can obtain the speed information, distance information and relative position information of the moving object when the moving object enters the monitoring range of the sensor. The monitoring range is related to the setting of the sensor and is not limited in the embodiment of the present invention.

[0097] S202. Determine door opening warning parameter information of the door on the same side as the moving object according to the relative position information.

[0098] Exemplarily, the door opening warning parameter information indicates the corresponding relationship between the speed and the warning range. Optionally, as mentioned above, the door opening warning parameter information can be determined based on the heart rate variability data of the test person.

[0099] In some possible implementations, a parameter library may be preset in the target vehicle, and the parameter library includes door opening warning parameter information at multiple relative positions, and the door opening warning parameter information at different relative positions can reflect the traffic conditions on different sides. For example, Table 2 is a schematic diagram of a parameter library provided in an embodiment of the present invention.

[0100] Table 2 Parameter library

[0101]

[0102] Therefore, referring to Table 2, the body controller can determine whether the moving object is on the main driver's side or the co-driver's side of the target vehicle based on the relative position information, and determine which door to issue a door opening warning for to prevent false alarms, and then obtain the door opening warning parameter information of the door on the same side as the moving object based on the relative position information. It should be noted that the storage location of the parameter library is not limited in the embodiment of the present invention, for example, it can be stored in a cloud server, and the target vehicle can obtain the parameter library from the cloud server, or it can be pre-set in the memory of the target vehicle or in the body controller.

[0103] S203: Determine the warning range corresponding to the moving object according to the door opening warning parameter information and speed information.

[0104] Exemplarily, as mentioned above, the door opening warning parameter information can indicate the corresponding relationship between the speed and the warning range. Therefore, the vehicle body controller can determine the warning range corresponding to the moving object based on the door opening warning parameter information and the speed information.

[0105] S204: If it is determined based on the distance information that the moving object has entered the warning range, a door opening warning is issued for the door of the target vehicle on the same side as the moving object.

[0106] For example, the vehicle body controller can compare the distance information with the size relationship of the warning range in real time. When the moving object enters the warning range, the door opening warning is issued to the door on the same side of the target vehicle as the moving object. The door opening warning method may include sound prompts, visual prompts (such as warning icons on the display screen inside the vehicle), vibration prompts, etc., or a combination of multiple methods. It should be noted that the embodiment of the present invention does not limit the door opening warning method.

[0107] The vehicle door opening warning method provided by the embodiment of the present invention uses the relative position information between the moving object and the target vehicle to determine the door opening warning parameter information of the door on the same side as the moving object, and determines the warning range corresponding to the moving object according to the speed of the moving object, and uses the distance information between the target vehicle and the moving object to perform a door opening warning on the door on the same side as the moving object in the target vehicle after determining that the moving object has entered the warning range. In this way, considering the speed of the moving object and the different traffic conditions corresponding to the relative position information between the moving object and the target vehicle, a warning range that is more suitable for the moving object can be obtained, which can improve the accuracy of the warning range and the accuracy of the door opening warning compared to the fixed warning range set in the prior art; at the same time, using the relative position information between the moving object and the target vehicle, a door opening warning can be performed only for the door on the same side as the moving object, thereby preventing false alarms and improving user experience.

[0108] Figure 3 This is a flow chart of a vehicle door opening warning method provided by an embodiment of the present invention. Figure 3 As shown, in this embodiment Figure 2 Based on the embodiment shown, the vehicle door opening warning method provided by the present invention is further described, and the method includes:

[0109] S301. When a target vehicle is stationary, obtain speed information of a moving object, distance information between the moving object and the target vehicle, and relative position information between the moving object and the target vehicle.

[0110] It should be noted that this step is similar to the aforementioned step S201 and will not be repeated here.

[0111] S302: Determine whether to issue a door opening warning based on the relative position information and the position information of the user in the target vehicle.

[0112] For example, there may be a situation where there is no passenger in the seat of the target vehicle on the same side as the moving object. In this case, even if there is a moving object, the door opening warning is not performed to prevent false alarms of the door opening warning and improve the accuracy of the door opening warning. Therefore, the body controller can obtain the data of the pressure sensor of the target vehicle to determine the position information of the user in the target vehicle. If the position information is consistent with the relative position information, the door opening warning step is performed. If not, the door opening warning step is not performed.

[0113] If yes, execute step S303; if no, do not perform door opening warning.

[0114] S303: Determine door opening warning parameter information of the door on the same side as the moving object according to the relative position information.

[0115] Exemplarily, the door opening warning parameter information includes at least one level of door opening warning parameters; each level of door opening warning parameters can represent the warning range of that level. For example, Table 3 is a schematic diagram of another parameter library provided by an embodiment of the present invention.

[0116] Table 3 Parameter library

[0117]

[0118] S304: Determine the warning range of each level corresponding to the moving object according to the door opening warning parameters and speed information of each level.

[0119] Exemplarily, referring to Table 3, the vehicle body controller can determine the warning range of each level corresponding to the moving object according to the door opening warning parameters of each level in the door opening parameter information under the relative position, and the speed information. For example, the door opening parameter information includes the first-level door opening warning parameter and the second-level door opening warning parameter, the first-level door opening warning parameter corresponds to the first-level warning range, the second-level door opening warning parameter corresponds to the second-level warning range, and the distance between the moving object and the target vehicle indicated by the first-level warning range is greater than or equal to the distance between the moving object and the target vehicle indicated by the second-level warning range. The speed information of the moving object is 20km / h. Taking the first-level door opening warning parameter of the main driver's side as S1=0.368v+11.773 as an example, the first-level warning range is less than or equal to 19.133m. Taking the second-level door opening warning parameter of the main driver's side as S2=0.151v-0.873 as an example, the second-level warning range is less than or equal to 2.147m.

[0120] S305: If it is determined based on the distance information that the moving object has entered the warning range, a door opening warning is issued for the door on the same side of the target vehicle as the moving object based on the warning range and the state of the door on the same side as the moving object.

[0121] For example, in this step, as the distance information between the moving object and the target vehicle changes, the moving object may enter different warning ranges, and then different door opening warning methods may be adopted according to the state of the door on the same side as the moving object. In other words, according to the warning range and the state of the door on the same side as the moving object, a door opening warning may be performed on the door on the same side as the moving object in the target vehicle. The following is an example of the warning range being the first-level warning range or the second-level warning range:

[0122] The first case: If it is determined based on the distance information that the moving object has entered the first-level warning range, and it is determined that the doors on the same side as the moving object are all in a closed state, a warning is given based on the ambient light on the door on the same side as the moving object; if it is determined based on the distance information that the moving object has entered the first-level warning range, and it is determined that any door on the same side as the moving object is in an open state, a voice prompt warning is given based on the speaker located on the open door.

[0123] In this way, since it is safer for passengers to open the door to get off the vehicle within the first warning range, in this case, if the door is not opened, only the ambient light can be turned on to give a door opening warning reminder to remind the passenger that there is a moving object behind, and the door opening warning is only given for the ambient light of the door on the same side as the moving object, thereby improving the accuracy of the door opening warning and the user experience; if the door is opened, a voice prompt is given using the speaker to remind the passenger to pay attention to the moving object behind.

[0124] The second situation: If it is determined based on the distance information that the moving object has entered the second-level warning range, and when it is determined that the doors on the same side as the moving object are all in the closed state, the doors on the same side as the moving object are controlled to be locked, and a warning is issued based on the ambient light on the doors on the same side as the moving object.

[0125] If the user enters the second-level warning range and the door on the same side as the moving object is locked, but the user insists on opening the door and getting out of the vehicle, the locked door will be unlocked in response to the user's first opening instruction for the locked door at the first moment, and a voice prompt warning will be given based on the speaker on the locked door; the unlocked door will be opened in response to the user's second opening instruction for the unlocked door at a second moment later than the first moment. The first opening instruction and the second opening instruction represent the door opening instructions, which can be generated by the user triggering the door opening key.

[0126] In this way, since it is unsafe for passengers to open the door to get off the vehicle within the second warning range and the risk of collision is high, in this case, if the door is not opened, the ambient light is turned on to give a door opening warning reminder to remind the passenger that there is a moving object behind the rear, and at the same time, the door on the same side as the moving object is controlled to be locked to prevent the passenger from opening the door and getting off the vehicle at this time, thereby ensuring the safety of the passenger; but if the passenger presses the door opening button of the locked door at this time to trigger the opening command for the locked door, the locked door will be unlocked, and a voice prompt warning will be given based on the speaker on the locked door to remind the passenger again that there is a moving object behind the rear; if the passenger presses the door opening button of the unlocked door again at this time to trigger the second opening command for the unlocked door, that is, the door opening button of the locked door is pressed twice in succession, the unlocked door will be opened.

[0127] The vehicle door opening warning method provided by the embodiment of the present invention uses the relative position information of the moving object and the target vehicle to determine the door opening warning parameter information of the door on the same side as the moving object, and determines the multi-level warning range corresponding to the moving object according to the speed of the moving object, and uses the distance information between the target vehicle and the moving object to perform a door opening warning on the door on the same side as the moving object in the target vehicle when it is determined that the moving object enters each level of the warning range. In this way, considering the speed of the moving object and the different traffic conditions corresponding to the relative position information between the moving object and the target vehicle, a warning range that is more suitable for the moving object can be obtained, and compared with the fixed warning range set in the prior art, the accuracy of the warning range can be improved, and the accuracy of the door opening warning can be improved; at the same time, a multi-level warning range is set, and when the moving object enters different warning ranges, different door opening warning methods can be adopted to improve the accuracy of the door opening warning.
