DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0025] The airbag ignition algorithm refers to a comprehensive judgment of ignition conditions based on the occupant collision injury requirements of various safety regulations to solve the problem of whether the airbag needs to be ignited and when to ignite.

[0026] The airbag controller (SRECU, Supplemental Restraint System Electronic Control Unit) generally refers to an electronic airbag control system based on bus-type peripheral acceleration sensors, door pressure sensors and multi-axis gyroscopes, using the main control MCU (Microcontroller Unit) and built-in algorithms for identifying multiple working conditions. It can sense the vehicle's driving status, predict collision damage and perform corresponding actions.

[0027] It can be seen that vehicle collision type recognition is an important function of the airbag controller, which is crucial to the operation of the airbag ignition algorithm. At present, in order to improve the accuracy of collision type recognition, sensors are arranged at various key positions of the vehicle, which not only has higher requirements and restrictions on the installation position, but also increases the cost of the sensor, making it impossible to popularize it in all vehicles.

[0028] In view of this, the embodiments of the present application provide a vehicle collision processing method, storage medium, electronic device and vehicle, which only require two sensors to identify the collision type, thereby reducing costs while ensuring recognition accuracy and can be widely used in various vehicles.

[0029] According to a first aspect of the present application, an embodiment of the present application provides a vehicle collision handling method.

[0030] See also Figure 1 , Figure 1 : is a flow chart of a vehicle collision processing method provided by an embodiment of the present application. The vehicle collision processing method may include the following steps: Step S110: determining the left front longitudinal acceleration integral and the right front longitudinal acceleration integral of the vehicle within a preset time period when the vehicle collides; Step S120: Determine the collision type according to the left front longitudinal acceleration integral and the right front longitudinal acceleration integral.

[0031] The left front longitudinal acceleration integral refers to the integral of the longitudinal acceleration obtained by the left front collision sensor of the vehicle, and the right front longitudinal acceleration integral refers to the integral of the longitudinal acceleration obtained by the right front collision sensor of the vehicle. The embodiment of the present application only needs to install two sensors, the left front collision sensor and the right front collision sensor, in the vehicle to realize the identification of the collision type, which effectively reduces the cost.

[0032] Optionally, the left front collision sensor and the right front collision sensor are both single-axis sensors. Of course, one or more of the left front collision sensor and the right front collision sensor may also be dual-axis sensors, etc., which is not limited in the embodiments of the present application. In practical applications, due to the cost of sensors, the left front collision sensor and the right front collision sensor can be implemented as single-axis sensors to achieve the purpose of collision type identification. The embodiments of the present application also do not limit the accuracy of the left front collision sensor and the right front collision sensor. For example, the accuracy of the left front collision sensor and the right front collision sensor is 2 LSB / g.

[0033] Optionally, the left front collision sensor is arranged on the left front longitudinal beam of the vehicle, and the right front collision sensor is arranged on the right front longitudinal beam of the vehicle. Figure 2 As shown, a left front collision sensor 212 is installed on the left front longitudinal beam of the vehicle, and a right front collision sensor 214 is installed on the right front longitudinal beam of the vehicle, and the left front collision sensor 212 and the right front collision sensor 214 are symmetrical. Of course, the left front collision sensor and the right front collision sensor can also be installed at other positions of the vehicle, and the embodiment of the present application does not limit this. Considering that in some embodiments, the acceleration obtained by the left front collision sensor and the right front collision sensor is needed to determine the left and right collision types, the left front collision sensor and the right front collision sensor can be installed symmetrically in front of the vehicle.

[0034] In the embodiment of the present application, the left front collision sensor and the right front collision sensor are both used to obtain the longitudinal acceleration of the vehicle, so the left front collision sensor and the right front collision sensor can be installed longitudinally in the vehicle. Figure 2 As shown, the left front collision sensor 212 and the right front collision sensor 214 are longitudinally mounted on the left front longitudinal beam and the right front longitudinal beam of the vehicle, respectively. Of course, the left front collision sensor and the right front collision sensor may also be non-longitudinally mounted, which is not limited in the embodiment of the present application. In the case of non-longitudinally mounted, the longitudinal acceleration corresponding to the left front collision sensor can be obtained by mapping the acceleration obtained by the left front collision sensor to the longitudinal direction of the vehicle, and the longitudinal acceleration corresponding to the right front collision sensor can be obtained by mapping the acceleration obtained by the right front collision sensor to the longitudinal direction of the vehicle.

[0035] During a preset time period when the vehicle collides, the left front collision sensor and the right front collision sensor can periodically collect longitudinal acceleration, so that steps S110 and S120 in the embodiment of the present application are also executed periodically. Optionally, the left front collision sensor and the right front collision sensor are connected to the airbag controller via the PSI5 bus, and the longitudinal acceleration is collected in a cycle of 0.5 ms (milliseconds).

[0036] In step S110, the left front longitudinal acceleration integral of the vehicle is calculated according to the longitudinal acceleration obtained by the left front collision sensor, and the right front longitudinal acceleration integral of the vehicle is calculated according to the longitudinal acceleration obtained by the right front collision sensor. In step S120, the collision type is determined according to the left front longitudinal acceleration integral and the right front longitudinal acceleration integral. However, in the embodiment of the present application, steps S110 and S120 are only valid within a preset time period when the vehicle collides, that is, steps S110 and S120 are only executed or periodically executed within a preset time period when the vehicle collides.

[0037] Optionally, the preset time period can be the time when the vehicle collides, or the time when the airbag ignition algorithm is awakened after the vehicle collides, which is not limited in the present embodiment. The airbag ignition algorithm can be divided into a continuous type and a wake-up type. When the wake-up type is used, a certain acceleration input is required to wake up the airbag ignition algorithm.

[0038] The embodiment of the present application does not limit the duration of the preset time period, and can be flexibly set in combination with actual needs. Optionally, since even a weak collision generated at a low speed of 15 km / h can integrate a larger value in a relatively long time, a low-speed head-on collision generally has a collapse process with a weak acceleration in the initial stage of the collision, and a medium- and high-speed collision has a relatively large acceleration in the initial stage of the collision, so based on this characteristic, the low, medium, and high-speed working conditions can be identified in a relatively short time after the collision occurs, so a smaller duration can be set for the preset time period. For example, the duration of the preset time period is 10ms, and if steps S110 and S120 are executed with a cycle of 0.5ms, the embodiment of the present application lasts for 20 cycles, that is, steps S110 and S120 are only valid within 20 cycles after the collision occurs.

[0039] In summary, the vehicle collision processing method provided by the embodiment of the present application determines the left front longitudinal acceleration integral according to the longitudinal acceleration obtained by the left front collision sensor of the vehicle, determines the right front longitudinal acceleration integral according to the longitudinal acceleration obtained by the right front collision sensor of the vehicle, and then determines the collision type of the vehicle according to the left front longitudinal acceleration integral and the right front longitudinal acceleration integral. Since the embodiment of the present application only needs to install the left front collision sensor and the right front collision sensor in the vehicle to realize the identification of the collision type, the sensor cost is greatly reduced; and the left front collision sensor and the right front collision sensor only need to be implemented as single-axis sensors, which further reduces the sensor cost. In addition, the embodiment of the present application performs an integral operation on the longitudinal acceleration obtained by the sensor within the preset time period when the vehicle collides, and identifies the collision type according to the integral result. Since the acceleration integrals of different collision states differ greatly, the collision type is determined by the acceleration integral operation within the preset time period, which ensures the accuracy of the collision type identification.

[0040] In some embodiments, the above step S120 includes the following steps: Step S121: determining the strong or weak collision type of the collision according to the integral sum of the left front longitudinal acceleration integral and the right front longitudinal acceleration integral; Step S122: Determine the left-right collision type of the collision according to the integral difference between the left front longitudinal acceleration integral and the right front longitudinal acceleration integral.

[0041] In the embodiment of the present application, the collision type includes a strong and weak collision type and a left and right collision type. By combining the strong and weak collision type and the left and right collision type, different collision states can be identified. Optionally, the determination process of the strong and weak collision type and the left and right collision type, that is, the above steps S121 and S122, can be performed in parallel or in series, and the embodiment of the present application does not limit this.

[0042] Optionally, the strong and weak collision types include strong collision, secondary strong collision or weak collision, and the strong collision is indicated by the flag bit intensity_flag, the secondary strong collision is indicated by the flag bit secondary_flag, and the weak collision is indicated by the flag bit feeble_flag; the left and right collision types include left collision, right collision or head-on collision, and the left collision is indicated by the flag bit left_crash_flag, the right collision is indicated by the flag bit right_crash_flag, and the head-on collision is indicated by the flag bit else; then the recognition of different collision states according to the combination of strong and weak collision types and left and right collision types can be as follows Figure 3 shown.

[0043] It should be understood that a strong collision is generally generated based on a high-speed collision, a secondary strong collision is generally generated based on a medium-speed collision, and a weak collision is generally generated based on a low-speed collision. Therefore, in the embodiments of the present application, a strong collision can correspond to a high-speed collision, a secondary strong collision can correspond to a medium-speed collision, and a weak collision can correspond to a low-speed collision, but the embodiments of the present application are not limited to this. For example, in the high-speed, medium-speed, and low-speed collisions divided by some embodiments, a strong collision corresponds to a high-speed collision, a secondary strong collision corresponds to a medium-speed collision, and a weak collision corresponds to a low-speed collision; while in the high-speed, medium-speed, and low-speed collisions divided by other embodiments, a strong collision corresponds to a high-speed collision and / or a medium-speed collision, a secondary strong collision corresponds to a medium-speed collision and / or a low-speed collision, and a weak collision corresponds to a low-speed collision, and so on. For another example, in some embodiments, under the division of strong collision, medium-strong collision and weak collision, high-speed collision corresponds to strong collision, medium-speed collision corresponds to medium-strong collision, and low-speed collision corresponds to weak collision; while in other embodiments, under the division of strong collision, medium-strong collision and weak collision, high-speed collision corresponds to strong collision and / or medium-strong collision, medium-speed collision corresponds to medium-strong collision and / or weak collision, low-speed collision corresponds to weak collision, and so on.

[0044] Optionally, in order to identify the three strong and weak collision types of strong collision, sub-strong collision and weak collision, a strong collision threshold and a weak collision threshold are preset in the embodiment of the present application, and the strong collision threshold is greater than the weak collision threshold; based on this, the above step S121 includes: when the integral sum is greater than the preset strong collision threshold, determining the strong and weak collision type of the collision is a strong collision; when the integral sum is less than the preset weak collision threshold, determining the strong and weak collision type of the collision is a weak collision; when the integral sum is greater than the weak collision threshold and less than the strong collision threshold, determining the strong and weak collision type of the collision is a sub-strong collision.

[0045] That is to say, Figure 4 As shown, after determining the left front longitudinal acceleration integral and the right front longitudinal acceleration integral of the vehicle, the left front longitudinal acceleration integral and the right front longitudinal acceleration integral are summed to obtain an integral sum, and then the integral sum is compared with the preset strong collision threshold and weak collision threshold.

[0046] For example, the longitudinal acceleration of the left front collision sensor is usl(x), and the longitudinal acceleration of the right front collision sensor is usr(x). Then, the integral of the left front longitudinal acceleration integral and the right front longitudinal acceleration integral and the integral of T_Power can be calculated as follows: T_Power=∫usl(x)dx+∫usr(x)dx Assume that the preset strong collision threshold is threshold_H and the preset weak collision threshold is threshold_L, and compare T_Power with threshold_H and threshold_L. Figure 4As shown, if T_Power is greater than threshold_H, the collision is determined to be a strong collision, and the intensity_flag flag of the strong collision can be set for the collision; if T_Power is less than threshold_L, the collision is determined to be a weak collision, and the feeble_flag flag of the weak collision can be set for the collision; if T_Power is greater than threshold_L and less than threshold_H, the collision is determined to be a secondary strong collision, and the secondary_flag flag of the secondary strong collision can be set for the collision.

[0047] It should be understood that when the integral sum of the left front longitudinal acceleration integral and the right front longitudinal acceleration integral is equal to the preset strong collision threshold, the collision can be determined as a strong collision, or it can be determined as a sub-strong collision, and the embodiment of the present application does not limit this. Similarly, when the integral sum of the left front longitudinal acceleration integral and the right front longitudinal acceleration integral is equal to the preset weak collision threshold, the collision can be determined as a sub-strong collision, or it can be determined as a weak collision, and the embodiment of the present application does not limit this.

[0048] Optionally, in order to identify the two left and right collision types of left collision and right collision, a bias threshold is preset in the embodiment of the present application. The bias threshold can be equal to zero or non-zero, such as a positive number close to zero, or a negative number close to zero; based on this, the above step S122 includes: when the integral difference is greater than the preset bias threshold, determining that the left and right collision type of the collision is a left collision; when the integral difference is less than the bias threshold, determining that the left and right collision type of the collision is a right collision.

[0049] That is to say, Figure 5 As shown, after determining the left front longitudinal acceleration integral and the right front longitudinal acceleration integral of the vehicle, the left front longitudinal acceleration integral and the right front longitudinal acceleration integral are subjected to difference processing to obtain the integral difference, and then the integral difference is compared with a preset bias threshold. Optionally, in order to ensure the accuracy of collision type identification, the embodiment of the present application performs difference processing on the absolute value of the left front longitudinal acceleration integral and the absolute value of the right front longitudinal acceleration integral to obtain the integral difference.

[0050] For example, the longitudinal acceleration of the left front collision sensor is usl(x), the longitudinal acceleration of the right front collision sensor is usr(x), and the absolute value is expressed as abs. Then, the calculation formula of the integral difference US_Dvalue between the left front longitudinal acceleration integral and the right front longitudinal acceleration integral can be: US_Dvalue=abs(∫usl(x)dx)-abs(∫usr(x)dx) Assume that the preset bias threshold is threshold_Front, and compare US_Dvalue with threshold_Front. Figure 5As shown, if US_Dvalue is greater than threshold_Front, the collision is determined to be a left collision, and the left collision flag left_crash_flag can be set for the collision; if US_Dvalue is less than threshold_Front, the collision is determined to be a right collision, and the right collision flag right_crash_flag can be set for the collision.

[0051] It should be understood that, in the above-mentioned embodiment, the integral difference is obtained based on the left front longitudinal acceleration integral minus the right front longitudinal acceleration integral, so when the integral difference is greater than the offset threshold, it is a left collision, and when the integral difference is less than the offset threshold, it is a right collision. In other embodiments, if the integral difference is obtained based on the right front longitudinal acceleration integral minus the left front longitudinal acceleration integral, then when the integral difference is greater than the offset threshold, it is a right collision, and when the integral difference is less than the offset threshold, it is a left collision. In addition, when the integral difference is equal to the offset threshold, it can be determined that the collision is a head-on collision.

[0052] In some embodiments, the vehicle collision processing method provided by the embodiments of the present application further includes the following steps: Step S130: determining the ignition logic to be executed for the airbag of the vehicle according to the collision type; Step S140: determining the ignition condition for the airbag according to the collision type; Step S150: When the ignition condition is met, the ignition logic to be executed is executed on the airbag.

[0053] In the airbag ignition algorithm, high-speed collision and medium-speed collision must be ignited, while low-speed collision cannot be ignited. Therefore, the ignition logic to be executed for the airbag in the embodiment of the present application may include left front high-speed ignition logic, left front medium-speed ignition logic, right front high-speed ignition logic and right front medium-speed ignition logic. For the corresponding relationship between high-speed, medium-speed, low-speed collision and strong collision, sub-strong collision and weak collision, please refer to the above embodiment, which will not be elaborated here.

[0054] It should be noted that in the embodiment of the present application, steps S110 and S120 are periodically executed within a preset time period when the vehicle collides; and steps S130 to S150 are executed after exceeding the preset time period.

[0055] Optionally, taking the collision types including strong and weak collision types and left and right collision types, the strong and weak collision types including strong collision, sub-strong collision or weak collision, and the left and right collision types including left collision or right collision as an example, the above step S130 includes: when the collision types include left collision and strong collision, determining that the ignition logic to be executed is the left front high-speed ignition logic; when the collision types include left collision and sub-strong collision, determining that the ignition logic to be executed is the left front medium-speed ignition logic; when the collision types include right collision and strong collision, determining that the ignition logic to be executed is the right front high-speed ignition logic; when the collision types include right collision and sub-strong collision, determining that the ignition logic to be executed is the right front medium-speed ignition logic.

[0056] For example, Figure 5 As shown, after exceeding the preset time period, different ignition logics to be executed are determined according to different combinations of left and right collision types and strong and weak collision types. Figure 5 As shown, when the left-right collision type is left collision (left_crash_flag), if the strong collision type is strong collision (intensity_flag), the ignition logic to be executed is determined to be the left front high-speed ignition logic (Lside_fire1 expectation); if the strong collision type is secondary collision (secondary_flag), the ignition logic to be executed is determined to be the left front medium-speed ignition logic (Lside_fire2expectation). Figure 5 As shown, when the left and right collision type is a right collision (right_crash_flag), if the strong and weak collision type is a strong collision (intensity_flag), the ignition logic to be executed is determined to be the right front high-speed ignition logic (Rside_fire1 expectation); if the strong and weak collision type is a secondary strong collision (secondary_flag), the ignition logic to be executed is determined to be the right front medium-speed ignition logic (Rside_fire2 expectation).

[0057] The embodiment of the present application also sets an ignition condition for the airbag, and the above-determined ignition logic to be executed is executed only when the ignition condition is met. It can be seen from the above embodiment that in the airbag ignition algorithm, high-speed collision and medium-speed collision must be ignited, while low-speed collision cannot be ignited. Therefore, the embodiment of the present application sets the ignition condition according to the collision type.

[0058] Based on this, optionally, taking the collision type including strong and weak collision types and left and right collision types, and the strong and weak collision types including strong collision, sub-strong collision or weak collision as an example; the above step S140 includes: when the collision type includes a sub-strong collision, determining that the ignition condition includes a preset condition; when the collision type includes a strong collision, determining the first condition according to the preset condition and the collision duration; when the collision type includes a weak collision, determining the second condition according to the preset condition and the collision duration.

[0059] That is to say, the embodiment of the present application sets the ignition condition based on the sub-strong collision, and when the strong and weak collision types are strong collision and weak collision, the preset condition corresponding to the sub-strong collision is modified in a targeted manner to obtain the first condition corresponding to the strong collision and the second condition corresponding to the weak collision. Among them, the preset condition is the ignition condition for the airbag in the case of a sub-strong collision, the first condition is the ignition condition for the airbag in the case of a strong collision, and the second condition is the ignition condition for the airbag in the case of a weak collision.

[0060] The specific content of the ignition condition is not limited in the present embodiment. Optionally, the ignition condition includes an ignition threshold. Figure 2 As shown, the vehicle is also provided with a central dual-axis sensor 220. For example, the central dual-axis sensor 220 can be arranged at 45 degrees relative to the longitudinal axis or the transverse axis of the vehicle, and the accuracy can be 16 LSB / g. The specific arrangement and accuracy of the central dual-axis sensor are not limited in the embodiment of the present application. The acceleration collected by the central dual-axis sensor is mapped on the longitudinal axis of the vehicle to obtain the longitudinal acceleration, and then the ignition threshold and the longitudinal acceleration corresponding to the central dual-axis sensor are compared. When the longitudinal acceleration corresponding to the central dual-axis sensor is greater than the ignition threshold, the ignition logic to be executed determined for the airbag is executed; when the longitudinal acceleration corresponding to the central dual-axis sensor is less than the ignition threshold, the ignition logic to be executed determined for the airbag is not executed. Among them, when the longitudinal acceleration corresponding to the central dual-axis sensor is equal to the ignition threshold, the ignition logic can be executed or not.

[0061] When the ignition condition includes an ignition threshold, the embodiment of the present application executes the ignition logic in the early stage of the collision to meet the high-speed collision. When the strong or weak collision type is a strong collision, the preset ignition threshold is lowered and the ignition threshold is continuously increased as the collision duration increases.

[0062] Based on this, the above-mentioned preset conditions include a preset ignition threshold; the above-mentioned determination of the first condition based on the preset conditions and the collision duration of the collision includes: when the collision duration is less than the first adjustment duration, determining the first condition includes reducing the preset ignition threshold by a first preset correction value to obtain a first ignition threshold; when the collision duration is greater than the first adjustment duration and less than the second adjustment duration, determining the first condition includes reducing the preset ignition threshold by a second preset correction value to obtain a second ignition threshold; when the collision duration is greater than the second adjustment duration and less than the maximum ignition duration, determining the first condition includes the preset ignition threshold.

[0063] The starting time of the collision duration may be the starting time of the preset time period in step S110, or may be the time when the collision occurs, which is not limited in the embodiments of the present application. The maximum ignition duration is the maximum operating time of the preset airbag ignition algorithm, for example, the maximum ignition duration may be 150ms. In order to lower the preset ignition threshold and make the ignition threshold increase continuously with the increase of the collision duration, the first adjustment duration is less than the second adjustment duration, and the second adjustment duration is less than the maximum ignition duration; and the first preset correction value is greater than the second preset correction value.

[0064] For example, Figure 4 As shown, a preset ignition threshold is set for the airbag, and the strong and weak collision type corresponding to the preset ignition threshold is a secondary strong collision. Figure 4 As shown, when the strong or weak collision type is a strong collision, if the current collision duration is less than the first adjustment duration, the preset ignition threshold is reduced by the first preset correction value to obtain the first ignition threshold, that is, the first preset correction value ECU_X_threshold reduce1 is set; if the current collision duration is greater than the first adjustment duration and less than the second adjustment duration, the preset ignition threshold is reduced by the second preset correction value to obtain the second ignition threshold, that is, the second preset correction value ECU_X_threshold reduce2 is set; if the current collision duration is greater than the second adjustment duration and less than the maximum ignition duration, the ignition threshold is restored to the preset ignition threshold, that is, the preset ignition threshold ECU_X_threshold restore is set.

[0065] When the ignition condition includes an ignition threshold, the embodiment of the present application executes the ignition logic to meet the low-speed collision avoidance. When the strong or weak collision type is a weak collision, the preset ignition threshold is increased and the ignition threshold is continuously reduced as the collision duration increases.

[0066] Based on this, the above-mentioned preset conditions include a preset ignition threshold; the above-mentioned second condition is determined based on the preset conditions and the collision duration, including: when the collision duration is less than the third adjustment duration, determining the second condition includes increasing the preset ignition threshold by the third preset correction value to obtain a third ignition threshold; when the collision duration is greater than the third adjustment duration and less than the fourth adjustment duration, determining the second condition includes increasing the preset ignition threshold by the fourth preset correction value to obtain a fourth ignition threshold; when the collision duration is greater than the fourth adjustment duration and less than the maximum ignition duration, determining the second condition includes the preset ignition threshold; wherein the third adjustment duration is less than the fourth adjustment duration, and the fourth adjustment duration is less than the maximum ignition duration; the third preset correction value is greater than the fourth preset correction value.

[0067] The starting time of the collision duration may be the starting time of the preset time period in step S110, or may be the time when the collision occurs, which is not limited in the embodiment of the present application. The maximum ignition duration is the maximum operating time of the preset airbag ignition algorithm, for example, the maximum ignition duration may be 150ms. In order to increase the preset ignition threshold and make the ignition threshold decrease continuously as the collision duration increases, the third adjustment duration is less than the fourth adjustment duration, and the fourth adjustment duration is less than the maximum ignition duration; and the third preset correction value is greater than the fourth preset correction value.

[0068] For example, Figure 4 As shown, a preset ignition threshold is set for the airbag, and the strong and weak collision type corresponding to the preset ignition threshold is a secondary strong collision. Figure 4 As shown, when the strong or weak collision type is a weak collision, if the current collision duration is less than the third adjustment duration, the preset ignition threshold is increased by the third preset correction value to obtain the third ignition threshold, that is, the third preset correction value ECU_X_threshold improve1 is set; if the current collision duration is greater than the third adjustment duration and less than the fourth adjustment duration, the preset ignition threshold is increased by the fourth preset correction value to obtain the fourth ignition threshold, that is, the fourth preset correction value ECU_X_threshold improve2 is set; if the current collision duration is greater than the fourth adjustment duration and less than the maximum ignition duration, the ignition threshold is restored to the preset ignition threshold, that is, the preset ignition threshold ECU_X_threshold restore is set.

[0069] Optionally, in the above embodiment, the first adjustment duration may be the same as the third adjustment duration, the second adjustment duration may be the same as the fourth adjustment duration, the value of the first preset correction value may be the same as the value of the third preset correction value, and the value of the second preset correction value may be the same as the value of the fourth preset correction value. However, the embodiment of the present application is not limited thereto, and other durations and value setting methods may also be used in actual application.

[0070] It should be understood that the embodiments of the present application only illustrate the discrete adjustment of the preset ignition threshold by three segments in case of strong collision and weak collision, respectively. In actual application, the preset ignition threshold may also be discretely adjusted by two or four or other number of segments, or the preset ignition threshold may be continuously adjusted. In general, in case of strong collision, the preset ignition threshold is lowered and the ignition threshold is continuously increased as the collision duration increases, and in case of weak collision, the preset ignition threshold is raised and the ignition threshold is continuously decreased as the collision duration increases.

[0071] In summary, the vehicle collision handling method provided in the embodiment of the present application determines the ignition logic to be executed for the airbag according to the combination of strong and weak collision types and left and right collision types. Since the combination of strong and weak collision types and left and right collision types can realize the identification of multiple collision states, the ignition logic can be determined according to the combination, and the ignition logic can be determined for a variety of different collision states to ensure the accuracy of the ignition logic. In addition, the embodiment of the present application adaptively adjusts the ignition conditions for different strong and weak collision types. When the strong and weak collision type is a strong collision, the preset ignition threshold is lowered and the ignition threshold is continuously increased as the collision duration increases, so as to meet the ignition logic in the early stage of the high-speed collision; when the strong and weak collision type is a weak collision, the preset ignition threshold is increased and the ignition threshold is continuously reduced as the collision duration increases, so as to effectively avoid the execution of the ignition logic for low-speed collisions.
