[0028] The embodiments of this disclosure will now be clearly and completely described with reference to the accompanying drawings. The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0029] With the increasing popularity of new energy vehicles, the proportion of high-voltage battery packs in the whole vehicle is increasing day by day. Currently, high-voltage battery packs are generally located under the chassis. At the same time, in order to pursue handling and comfort, the ground clearance of the chassis is generally low.

[0030] Therefore, when a vehicle is driving on complex road surfaces, there is a possibility of scraping the chassis. If the high-voltage battery pack under the chassis is severely impacted, it can easily lead to a serious accident, thereby threatening the safety of the vehicle occupants.

[0031] How to protect a vehicle when it is involved in a collision has become an urgent problem to be solved.

[0032] In view of this, the present disclosure provides a vehicle collision protection method, which adopts corresponding preset protection measures to protect the target vehicle according to the current collision intensity and current load of the battery pack, thereby ensuring the safety of the target vehicle and avoiding serious accidents that threaten the safety of the occupants when the battery pack collides.

[0033] It should be noted that the vehicle collision protection method provided in this disclosure can be implemented by a vehicle collision protection device, electronic device, processor, computer, or similar device, and this disclosure does not limit this. The vehicle collision protection device can be implemented as part or all of the electronic device in an intelligent vehicle through software, hardware, or a combination of both. In the following method embodiments, the implementation subject is always an electronic device.

[0034] It should be noted that the steps shown in the flowchart can be executed in a computer system as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0035] This disclosure provides a vehicle scratch protection method, which can be used in the aforementioned electronic device. Figure 1 is a flowchart of the vehicle scratch protection method according to an embodiment of this disclosure. As shown in Figure 1, the vehicle scratch protection method includes the following steps S101 to S104.

[0036] In step S101, the mechanical wave vibration intensity at the target location of the target vehicle is obtained.

[0037] In this embodiment, the target position corresponds to a mounting position of a battery pack of the target vehicle.

[0038] For example, an elastic wave sensor can be installed at the target position to collect the mechanical wave vibration intensity of the target position. The electronic device can be communicatively connected with the elastic wave sensor installed at the target position to obtain the mechanical wave vibration intensity of the target position from the elastic wave sensor.

[0039] At step S102, the current collision intensity of the battery pack is determined according to the mechanical wave vibration intensity of the target position.

[0040] For example, the electronic device can compare the mechanical wave vibration intensity of the target position with a preset mechanical wave vibration intensity threshold, and determine the current collision intensity of the battery pack according to the comparison result.

[0041] This step S102 will be described in detail below.

[0042] At step S103, the current load of the battery pack is obtained.

[0043] For example, the electronic device can be communicatively connected with the battery pack system to obtain the current load of the battery pack from the battery pack system.

[0044] This step S103 will be described in detail below.

[0045] At step S104, the target vehicle is protected by using a corresponding preset protection measure according to the current collision intensity and the current load.

[0046] For example, the electronic device can find a preset protection measure corresponding to the current collision intensity and the current load according to the current collision intensity and the current load, and then protect the target vehicle based on the preset protection measure.

[0047] For example, the correspondence between the current collision intensity and the current load and the preset protection measure can be shown in Table 1 below. Table 1 Correspondence between current collision intensity and current load and preset protection measure

[0048] In Table 1, the first collision intensity is greater than the second collision intensity, the first load is higher than the second load, and the second load is higher than the third load.

[0049] In the vehicle scratch protection method provided in the embodiments of the present disclosure, the mechanical wave vibration intensity of the target position of the target vehicle is obtained, and the current collision intensity of the battery pack is determined according to the mechanical wave vibration intensity of the target position, which ensures the accuracy of the determined current collision intensity of the battery pack. The current load of the battery pack is obtained, and the corresponding preset protection measure is adopted to protect the target vehicle according to the current collision intensity and the current load, thereby ensuring the accuracy of protecting the target vehicle. The above method ensures the safety of the target vehicle, and avoids serious accidents and threats to the safety of the passengers in the vehicle when the battery pack collides.

[0050] A vehicle scratch protection method is provided in the embodiments of the present disclosure, which can be used for the electronic device described above. FIG. 2 is a flowchart of the vehicle scratch protection method according to the embodiments of the present disclosure. As shown in FIG. 2, the vehicle scratch protection method includes the following steps S201 to S204.

[0051] In step S201, the mechanical wave vibration intensity of the target position of the target vehicle is obtained.

[0052] In the present embodiment, the target position corresponds to the installation position of the battery pack of the target vehicle.

[0053] For details, please refer to step S101 of the embodiment shown in FIG. 1, which will not be repeated here.

[0054] In step S202, the current collision intensity of the battery pack is determined according to the mechanical wave vibration intensity of the target position.

[0055] The target position is multiple, and the above step S202 includes the following steps S2021 to S2028.

[0056] In step S2021, the mechanical wave vibration intensities of the multiple target positions are statistically analyzed to obtain a first statistical analysis result.

[0057] For example, the electronic device statistically analyzes the mechanical wave vibration intensities of the multiple target positions at the same time to obtain the first statistical analysis result. Due to the transmission of vibration waves, the electronic device can also statistically analyze the mechanical wave vibration intensities of the multiple target positions within a preset time to obtain the first statistical analysis result.

[0058] For example, the electronic device can obtain the mechanical wave vibration intensities Q1, Q2, Q3, …, Qn of the multiple target positions at t0, and can also obtain the mechanical wave vibration intensities Q1, Q2, Q3, …, Qn of the multiple target positions within [t1, t2].

[0059] Optionally, the electronic device can add the obtained mechanical wave vibration intensities of the multiple target positions to obtain the first statistical analysis result.

[0060] Optionally, the electronic device can also add the mechanical wave vibration intensities of the multiple target positions at the time t0, and then calculate the average value to obtain the first statistical analysis result.

[0061] The electronic device can also calculate the first statistical analysis result Q by using the following formula for the mechanical wave vibration intensities of the multiple target positions within the time interval [t1, t2].

[0062] The present disclosure does not make specific limitations on the manner in which the electronic device statistically analyzes the mechanical wave vibration intensities of the multiple target positions.

[0063] In step S2022, if the first statistical analysis result satisfies the preset vibration intensity condition, the current collision intensity is determined as the first collision intensity.

[0064] For example, the preset vibration intensity condition can be that the first statistical analysis result is greater than or equal to a target vibration intensity threshold.

[0065] The electronic device can receive the target vibration intensity threshold input by the user. Alternatively, the electronic device can also receive the target vibration intensity threshold sent by another device. Alternatively, the electronic device can also detect the flatness of the current road and set the target vibration intensity threshold according to the flatness of the current road. For example, in an embodiment of the present disclosure, the higher the flatness of the current road, the smaller the target vibration intensity threshold.

[0066] Then, the electronic device can compare the first statistical analysis result with the target vibration intensity threshold to detect whether the first statistical analysis result satisfies the preset vibration intensity condition.

[0067] If the first statistical analysis result is greater than or equal to the target vibration intensity threshold, it is determined that the first statistical analysis result satisfies the preset vibration intensity condition, and the current collision intensity is determined as the first collision intensity. In step S2023, if the first statistical analysis result does not satisfy the preset vibration intensity condition, the maximum mechanical wave vibration intensity is determined from the mechanical wave vibration intensities of the multiple target positions.

[0068] If the first statistical analysis result is less than the target vibration intensity threshold, it is determined that the first statistical analysis result does not satisfy the preset vibration intensity condition.

[0069] The electronic device compares the mechanical wave vibration intensities of the multiple target positions to determine the maximum mechanical wave vibration intensity from the mechanical wave vibration intensities of the multiple target positions.

[0070] In step S2024, the maximum mechanical wave vibration intensity is compared with the preset vibration intensity threshold.

[0071] The electronic device can receive a preset vibration intensity threshold input by a user. Alternatively, the electronic device can also receive a preset vibration intensity threshold sent by another device. Alternatively, the electronic device can also detect the flatness of the current road and set the preset vibration intensity threshold according to the flatness of the current road. For example, in an embodiment of the present disclosure, the higher the flatness of the current road, the smaller the preset vibration intensity threshold.

[0072] Then, the electronic device compares the maximum mechanical wave vibration intensity with the preset vibration intensity threshold.

[0073] In step S2025, if the maximum mechanical wave vibration intensity is less than the preset vibration intensity threshold, it is determined that the current collision intensity is the second collision intensity.

[0074] In an embodiment of the present disclosure, the preset vibration intensity threshold is less than or equal to the target vibration intensity threshold, and the second collision intensity is less than the first collision intensity.

[0075] For example, if the maximum mechanical wave vibration intensity is less than the preset vibration intensity threshold, it is determined that the mechanical wave vibration intensity of each target position within the preset range centered on the target position corresponding to the maximum mechanical wave vibration intensity also cannot meet the preset vibration intensity condition, and therefore the electronic device determines that the current collision intensity is the second collision intensity. In step S2026, if the maximum mechanical wave vibration intensity is greater than or equal to the preset vibration intensity threshold, the mechanical wave vibration intensity of each target position within the preset range centered on the target position corresponding to the maximum mechanical wave vibration intensity is statistically analyzed to obtain a second statistical analysis result.

[0076] For example, if the maximum mechanical wave vibration intensity is greater than or equal to the preset vibration intensity threshold, the electronic device needs to determine whether the mechanical wave vibration intensity of each target position within the preset range centered on the target position corresponding to the maximum mechanical wave vibration intensity can meet the preset vibration intensity condition. Therefore, the electronic device can statistically analyze the mechanical wave vibration intensity of each target position within the preset range centered on the target position corresponding to the maximum mechanical wave vibration intensity to obtain a second statistical analysis result.

[0077] In an embodiment of the present disclosure, the way of statistically analyzing the mechanical wave vibration intensity within the preset range to obtain the second statistical analysis result can refer to step S2021, which will not be described here.

[0078] It should be noted that the number of target positions within the preset range is less than the number of target positions in step S2021.

[0079] For example, the electronic device can statistically analyze the mechanical wave vibration intensity of the surrounding five target positions centered on the target position corresponding to the maximum mechanical wave vibration intensity to obtain a second statistical analysis result.

[0080] Exemplarily, the electronic device can take the target position corresponding to the maximum mechanical wave vibration intensity as the center, take 3 cm as the radius as the preset range, statistically analyze the mechanical wave vibration intensity of each target position in the preset range, and obtain a second statistical analysis result.

[0081] In step S2027, if the second statistical analysis result meets the preset vibration intensity condition, it is determined that the current collision intensity is the first collision intensity.

[0082] For example, the preset vibration intensity condition can be that the second statistical analysis result is greater than or equal to a target vibration intensity threshold.

[0083] The electronic device can receive a target vibration intensity threshold input by a user. Alternatively, the electronic device can also receive a target vibration intensity threshold sent by another device. Alternatively, the electronic device can also detect the flatness of the current road and set the target vibration intensity threshold according to the flatness of the current road. For example, in an embodiment of the present disclosure, the higher the flatness of the current road, the smaller the target vibration intensity threshold.

[0084] Then, the electronic device can compare the second statistical analysis result with the target vibration intensity threshold to detect whether the second statistical analysis result meets the preset vibration intensity condition.

[0085] If the second statistical analysis result is greater than or equal to the target vibration intensity threshold, it is determined that the second statistical analysis result meets the preset vibration intensity condition, and then it is determined that the current collision intensity is the first collision intensity.

[0086] In step S2028, if the second statistical analysis result does not meet the preset vibration intensity condition, it is determined that the current collision intensity is the second collision intensity.

[0087] If the second statistical analysis result is less than the target vibration intensity threshold, it is determined that the second statistical analysis result does not meet the preset vibration intensity condition, and then it is determined that the current collision intensity is the second collision intensity. In step S203, the current load of the battery pack is obtained.

[0088] For details, please refer to step S103 of the embodiment shown in FIG. 1, which will not be repeated here.

[0089] In step S204, according to the current collision intensity and the current load, a corresponding preset protection measure is adopted to protect the target vehicle.

[0090] For details, please refer to step S104 of the embodiment shown in FIG. 1, which will not be repeated here.

[0091] In the vehicle scratching protection method provided in the embodiments of the present disclosure, the target positions are multiple, the mechanical wave vibration intensities of the multiple target positions are statistically analyzed to obtain a first statistical analysis result, and the accuracy of the obtained first statistical analysis result is ensured. If the first statistical analysis result meets a preset vibration intensity condition, it is determined that the current collision intensity is a first collision intensity, and the accuracy of the determined current collision intensity being the first collision intensity is ensured.

[0092] If the first statistical analysis result does not meet the preset vibration intensity condition, the maximum mechanical wave vibration intensity is determined from the mechanical wave vibration intensities of the multiple target positions, and the accuracy of the determined maximum mechanical wave vibration intensity is ensured. The maximum mechanical wave vibration intensity is compared with a preset vibration intensity threshold value; if the maximum mechanical wave vibration intensity is less than the preset vibration intensity threshold value, it is determined that the current collision intensity is a second collision intensity, and the accuracy of the determined current collision intensity being the second collision intensity is ensured.

[0093] If the maximum mechanical wave vibration intensity is greater than or equal to the preset vibration intensity threshold value, the target position corresponding to the maximum mechanical wave vibration intensity is taken as the center, the mechanical wave vibration intensities of each target position in a preset range are statistically analyzed to obtain a second statistical analysis result, the accuracy of the obtained second statistical analysis result is ensured, and the second statistical analysis result can represent the local collision intensity of the target vehicle. If the second statistical analysis result meets the preset vibration intensity condition, it is determined that the current collision intensity is the first collision intensity, and the accuracy of the determined current collision intensity being the first collision intensity is ensured. If the second statistical analysis result does not meet the preset vibration intensity condition, it is determined that the current collision intensity is the second collision intensity, and the accuracy of the determined current collision intensity being the second collision intensity is ensured.

[0094] In the embodiments of the present disclosure, a vehicle scratching protection method is provided, which can be used for the electronic device described above. FIG. 3 is a flowchart of a vehicle scratching protection method according to an embodiment of the present disclosure. As shown in FIG. 3, the vehicle scratching protection method includes the following steps S301 to S309.

[0095] In step S301, the mechanical wave vibration intensity of a target position of a target vehicle is obtained, and the target position corresponds to the installation position of a battery pack of the target vehicle.

[0096] For details, please refer to step S201 of the embodiment shown in FIG. 2, which will not be repeated here.

[0097] In step S302, the current collision intensity of the battery pack is determined according to the mechanical wave vibration intensity of the target position.

[0098] For details, please refer to step S202 of the embodiment shown in FIG. 2, which will not be repeated here.

[0099] At step S303, a current load of the battery pack is acquired.

[0100] The step S303 can include a step S3031 and a step S3032.

[0101] At step S3031, at least one current operating parameter of the battery pack is acquired.

[0102] In an embodiment of the present disclosure, the current operating parameter can include at least one of a current temperature, a current voltage, a current current, and the like. The present disclosure does not make specific limitation on the operating parameter.

[0103] For example, the electronic device can be communicatively connected with the battery pack system to acquire at least one current operating parameter of the battery pack from the battery pack system.

[0104] At step S3032, the current load of the battery pack is determined according to a comparison result of the current operating parameter and a corresponding operating parameter threshold.

[0105] For example, the electronic device can determine the current load of the battery pack according to a comparison result of the current operating parameter and a corresponding operating parameter threshold.

[0106] In an optional implementation of the present disclosure, the electronic device can acquire a current temperature, a current voltage, and a current current of the battery pack.

[0107] The electronic device can compare the current temperature with a first temperature threshold and a second temperature threshold; the first temperature threshold is greater than the second temperature threshold; compare the current voltage with a first voltage threshold and a second voltage threshold; the first voltage threshold is greater than the second voltage threshold; compare the current current with a first current threshold and a second current threshold; the first current threshold is greater than the second current threshold.

[0108] Case 1: if the current temperature is greater than the first temperature threshold, and / or the current voltage is greater than the first voltage threshold, and / or the current current is greater than the first current threshold, then the current load is determined as a first load.

[0109] Case 2: if the current temperature is less than the second temperature threshold, and the current voltage is less than the second voltage threshold, and the current current is less than the second current threshold, then the current load is determined as a third load.

[0110] If the current temperature, the current voltage, and the current current are in other cases except the case 1 and the case 2, then the current load is determined as a second load; wherein the first load is greater than the second load, and the second load is greater than the third load.

[0111] At step S304, a corresponding preset protection measure is adopted to protect the target vehicle according to the current collision intensity and the current load.

[0112] Please refer to step S204 of the embodiment shown in FIG. 2 for details, which will not be repeated here.

[0113] At step S305, based on the mechanical wave vibration intensities of the target positions, the first boundary and the second boundary of the target obstacle relative to the target vehicle in a collision with the target vehicle are determined.

[0114] The above step S305 can include steps S3051 to S3056.

[0115] At step S3051, the maximum mechanical wave vibration intensity is determined from the mechanical wave vibration intensities of the plurality of target positions.

[0116] For example, the electronic device compares the mechanical wave vibration intensities of the plurality of target positions to determine the maximum mechanical wave vibration intensity from the mechanical wave vibration intensities of the plurality of target positions.

[0117] At step S3052, the first absolute value of the difference between the mechanical wave vibration intensities of the adjacent two target positions on the first side of the target position corresponding to the maximum mechanical wave vibration intensity is sequentially calculated with the target position corresponding to the maximum mechanical wave vibration intensity as the center to obtain a plurality of first absolute values corresponding to the first side, and the second absolute value of the difference between the mechanical wave vibration intensities of the adjacent two target positions on the second side of the target position corresponding to the maximum mechanical wave vibration intensity is sequentially calculated with the target position corresponding to the maximum mechanical wave vibration intensity as the center to obtain a plurality of second absolute values corresponding to the second side.

[0118] For example, the electronic device sequentially calculates the first absolute value of the difference between the mechanical wave vibration intensities of any adjacent two target positions on the first side of the target position corresponding to the maximum mechanical wave vibration intensity with the target position corresponding to the maximum mechanical wave vibration intensity as the center, and sequentially calculates the second absolute value of the difference between the mechanical wave vibration intensities of any adjacent two target positions on the second side of the target position corresponding to the maximum mechanical wave vibration intensity with the target position corresponding to the maximum mechanical wave vibration intensity as the center.

[0119] At step S3053, the maximum first absolute value is determined from the plurality of first absolute values, and the maximum second absolute value is determined from the plurality of second absolute values.

[0120] For example, the electronic device compares the plurality of first absolute values corresponding to the first side to determine the maximum first absolute value from the plurality of first absolute values, and compares the plurality of second absolute values corresponding to the second side to determine the maximum second absolute value from the plurality of second absolute values.

[0121] At step S3054, the two first target mechanical wave vibration intensities corresponding to the maximum first absolute value and the two second target mechanical wave vibration intensities corresponding to the maximum second absolute value are determined.

[0122] For example, the electronic device determines two first target mechanical wave vibration strengths corresponding to the maximum first absolute value, and two second target mechanical wave vibration strengths corresponding to the maximum second absolute value.

[0123] In step S3055, a center position of target positions corresponding to the two first target mechanical wave vibration strengths is determined as the first boundary.

[0124] For example, the electronic device determines a center position of target positions corresponding to the two first target mechanical wave vibration strengths as the first boundary.

[0125] In step S3056, a center position of target positions corresponding to the two second target mechanical wave vibration strengths is determined as the second boundary.

[0126] For example, the electronic device determines a center position of target positions corresponding to the two second target mechanical wave vibration strengths as the second boundary.

[0127] In step S306, the height of the target obstacle is determined based on the ground clearance of the target vehicle.

[0128] For example, the electronic device determines the height of the target obstacle according to the ground clearance of the target vehicle and the part of the target vehicle colliding with the target obstacle.

[0129] In step S307, the contour of the target obstacle is generated according to the first boundary and the second boundary and the height of the target obstacle.

[0130] For example, the electronic device can generate the contour of the target obstacle according to the first boundary and the second boundary and the height of the target obstacle.

[0131] In step S308, the position information of the target obstacle is determined based on the position information of the target vehicle.

[0132] For example, the electronic device can determine the position information of the target obstacle based on the position information of the target vehicle and the part of the target vehicle colliding with the target obstacle.

[0133] In step S309, the contour of the target obstacle and the position information of the target obstacle are uploaded to the server to alert other vehicles.

[0134] For example, the electronic device is in communication connection with the server to upload the contour of the target obstacle and the position information of the target obstacle to the server, thereby alerting other vehicles.

[0136] In addition, in the vehicle scratching protection method provided in the embodiments of the present disclosure, the maximum mechanical wave vibration intensity is determined from the mechanical wave vibration intensities of the plurality of target positions, thereby ensuring the accuracy of the determined maximum mechanical wave vibration intensity.

The maximum first absolute value is determined from the plurality of first absolute values, and the maximum second absolute value is determined from the plurality of second absolute values, thereby ensuring the accuracy of the determined maximum first absolute value and maximum second absolute value, and enabling the position with the largest change in mechanical wave vibration intensity to be determined according to the maximum first absolute value and the maximum second absolute value. Then, the two first target mechanical wave vibration intensities corresponding to the maximum first absolute value and the two second target mechanical wave vibration intensities corresponding to the maximum second absolute value are determined, thereby ensuring that the intensity change between the two first target mechanical wave vibration intensities is the largest on the first side of the target position corresponding to the maximum mechanical wave vibration intensity, and the intensity change between the two second target mechanical wave vibration intensities is the largest on the second side of the target position corresponding to the maximum mechanical wave vibration intensity. Thus, the accuracy of determining the center position of the target positions corresponding to the two first target mechanical wave vibration intensities as the first boundary and the center position of the target positions corresponding to the two second target mechanical wave vibration intensities as the second boundary is ensured. The height of the target obstacle is determined based on the ground clearance of the target vehicle, thereby ensuring the accuracy of the determined height of the target obstacle. The profile of the target obstacle is generated according to the first boundary and the second boundary and the height of the target obstacle, thereby ensuring the accuracy of the generated profile of the target obstacle. The position information of the target obstacle is determined based on the position information of the target vehicle, thereby ensuring the accuracy of the determined position information of the target obstacle. The profile of the target obstacle and the position information of the target obstacle are uploaded to a server to remind other vehicles, thereby avoiding the collision between the other vehicles and the target obstacle, and further ensuring the safety of the other vehicles.
