DETAILED DESCRIPTION

[0040] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0041] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0042] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0043] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0044] When a car collides, the airbag controller drives the ignition device to ignite and generate gas, which is instantly injected into the airbag to inflate and expand, thereby protecting passengers from impact injuries. Seat belts are another passenger safety protection device besides airbags. In the early stage of a car collision, the seat belt is pre-tightened to effectively restrain the passengers, thereby protecting the passengers.

[0045] In a frontal collision, the seat belt pretensioner and airbag ignition method is unified centralized ignition, that is, the airbag, seat belt pretensioner, and different passenger positions are ignited at the same time. Ignition accuracy is a crucial factor in the passive safety protection effect of passengers. Obviously, the accuracy of this unified centralized ignition still has room for improvement.

[0046] In addition, most airbags are disposable, which means that after being opened, they can only be replaced or repaired, and cannot be reinstalled and reused. Therefore, this centralized ignition may lead to unnecessary consumption of airbags and increase the cost of subsequent maintenance.

[0047] like Figure 1 As shown, the embodiment of the present application provides an ignition method for a vehicle safety measure, comprising: S100, obtaining collision information of the vehicle.

[0048] The collision information is used to characterize the collision degree of the vehicle. In step S100, the collision information of the vehicle can be obtained through a collision sensor, or through an acceleration sensor combined with calculation processing.

[0049] In a possible implementation, obtaining the collision information of the vehicle includes: S110, obtaining collision acceleration information of the vehicle.

[0050] In step S110 , the collision acceleration information of the vehicle may be acquired through an acceleration sensor.

[0051] In a possible implementation manner, the collision acceleration information of the vehicle includes first collision acceleration information, second collision acceleration information, and third collision acceleration information.

[0052] In a possible implementation, obtaining the collision acceleration information of the vehicle includes: S111, obtaining a collision acceleration signal of the vehicle, the collision acceleration signal including a first acceleration signal A_fl, a second acceleration signal A_fr and a third acceleration signal A_axy. Figure 2 As shown, the first acceleration signal A_fl is obtained by the first acceleration sensor 201 located at the left front part of the vehicle body 200, the second acceleration signal A_fr is obtained by the second acceleration sensor 202 located at the right front part of the vehicle body 200, and the third acceleration signal A_axy is obtained by the third acceleration sensor 203 located at the middle part of the vehicle body 200. The angle α between the first sensing direction Z of the third acceleration sensor 203 and the first direction X of the vehicle body is an acute angle, and the first direction X is parallel to the straight direction of the vehicle.

[0053] In step S111, the first acceleration sensor 201 is fixedly mounted on the left front part of the vehicle body, for example, the first acceleration sensor 201 is fixedly mounted on the vehicle body near or around the left front headlight. For example, the first acceleration sensor 201 is mounted on the vehicle frame, and the distance from the left front headlight is less than or equal to the set threshold, and the set threshold may be 10-30cm. The second acceleration sensor 202 is fixedly mounted on the right front part of the vehicle body, for example, the second acceleration sensor 202 is fixedly mounted on the vehicle body near or around the right front headlight. For example, the second acceleration sensor 202 is mounted on the vehicle frame, and the distance from the right front headlight is less than or equal to the set threshold, and the set threshold may be 10-30cm.

[0054] The first acceleration signal A_fl is used to characterize the first acceleration. The second acceleration signal A_fr is used to characterize the second acceleration. The direction of the first acceleration is parallel to the first direction. The direction of the second acceleration is parallel to the first direction.

[0055] The third acceleration sensor 203 is fixedly mounted on the middle part of the vehicle body 200. In a possible implementation, the middle part may be within a range of 0-50 cm from the center of the vehicle body. In a possible implementation, the third acceleration sensor is fixedly mounted on the vehicle body and is located in the cab.

[0056] The first sensing direction Z of the third acceleration sensor 203 is one of its working directions, and the working direction is the direction of acceleration collected when the acceleration sensor is working. Taking the third acceleration sensor as a capacitive acceleration sensor as an example, the first sensing direction can be the direction of movement of the capacitor plate in the capacitive acceleration sensor.

[0057] The first sensing direction Z of the third acceleration sensor 203 forms an acute angle with the first direction X, so that the third acceleration sensor 203 can collect multiple accelerations and then synthesize the multiple accelerations to obtain the final acceleration, so as to improve the accuracy of the information.

[0058] In a possible implementation, the angle between the first sensing direction Z of the third acceleration sensor 203 and the first direction X of the vehicle body 200 is 45 degrees.

[0059] The angle between the first sensing direction Z of the third acceleration sensor 203 and the first direction X of the vehicle body 200 is 45 degrees. After the acceleration synthesis, the final acceleration signal can accurately reflect the collision condition of the vehicle.

[0060] For example, in a possible implementation, obtaining a collision acceleration signal of a vehicle includes: The first sub-acceleration A_ax and the second sub-acceleration A_ay are obtained by the third acceleration sensor 203, the direction of the first sub-acceleration A_ax is perpendicular to the direction of the second sub-acceleration A_ay, and the first sub-acceleration A_ax is parallel to the first sensing direction Z. The third acceleration signal A_axy is the component of the sum of the first sub-acceleration A_ax and the second sub-acceleration A_ay in the first direction.

[0061] The first sub-acceleration is obtained by the sensing component working in the first sensing direction, and the second sub-acceleration is obtained by the sensing component working in the second sensing direction. The first sensing direction is parallel to the second sensing direction. After the third acceleration sensor obtains the first sub-acceleration and the second sub-acceleration, the processing unit will merge the first sub-acceleration and the second sub-acceleration, for example, add them, and use the sum of the components in the first direction as the third acceleration signal.

[0062] S112, filtering the collision acceleration signal of the vehicle.

[0063] In step S112, the filtering process includes high-pass filtering and low-pass filtering. The filtering process can effectively remove noise signals.

[0064] In step S112, the first acceleration signal is filtered to obtain a first intermediate acceleration signal, the second acceleration signal is filtered to obtain a second intermediate acceleration signal, and the third acceleration signal is filtered to obtain a third intermediate acceleration signal.

[0065] S113, normalizing the collision acceleration signal of the vehicle after the filtering process to obtain collision acceleration information of the vehicle.

[0066] In step S113, if Figure 3 As shown, the first intermediate acceleration signal is normalized to obtain the first collision acceleration information D_fl, the second intermediate acceleration signal is normalized to obtain the second collision acceleration information D_fr, and the third intermediate acceleration signal is normalized to obtain the third collision acceleration information D_ax. The normalization process may be an analog-to-digital conversion process, and after the normalization process, the first collision acceleration information, the second collision acceleration information, and the third collision acceleration information can be converted into data within a preset range. In a possible implementation, the preset range may be [-512, 512].

[0067] S120, performing data processing on the collision acceleration information of the vehicle to obtain the collision information of the vehicle.

[0068] In step S120, after the collision acceleration information is obtained, the collision information of the vehicle is obtained by performing calculation processing on the collision acceleration information.

[0069] In a possible implementation manner, the collision information of the vehicle includes: a first collision degree, a second collision degree, a third collision degree, a fourth collision degree, a fifth collision degree, and a sixth collision degree.

[0070] The collision acceleration information of the vehicle is processed to obtain the collision information of the vehicle including: S121, the third collision acceleration information D_ax Perform integral operation to obtain the first collision degree A lg0-1. For example:

[0071] Wherein, t is the calculation time start time. t-len is the end point of the preset time length starting from the time start time. For example, if the time start time t is 1s and the time preset length is 5s, then t-len is 6s. The t and t-len in the following text can refer to the above explanation.

[0072] S122, first collision acceleration information D_fl Perform an integral operation to obtain the second collision degree A lg0-2. For example:

[0073] S123, the second collision acceleration information D_fr Perform integral operation to obtain the third collision degree A lg0-3. For example:

[0074] S124, the third collision acceleration information D_ax With the first collision acceleration information D_fl The fourth collision degree is obtained by integrating the difference between A lg0-4. For example:

[0075] S125, the third collision acceleration information D_ax With the second collision acceleration information D_fr The fifth collision degree is obtained by integrating the difference between A lg0-5. For example:

[0076] S126, the third collision acceleration information D_ax Perform full integral operation to obtain the sixth collision degree A lg0-6. For example:

[0077] It should be noted that the execution order of steps S121, S122, S123, S124, S125 and S126 is not limited here. That is, the execution order of the six steps is not prioritized. For example, the six steps can be executed serially, in parallel, or partially in serial and partially in parallel.

[0078] S200, determining at least one effective ignition level of the vehicle based on the collision information of the vehicle, wherein the collision information of the vehicle satisfies a preset condition of the effective ignition level.

[0079] In step S200, by comparing the collision degree Algo-i of the vehicle with the preset threshold Thr_i, the effective ignition level of the vehicle can be determined. The effective ignition level is a condition for executing safety measures. Only when the effective ignition level of the vehicle is determined can the safety measures be accurately executed, and ultimately the accuracy of the safety measures control can be improved.

[0080] Combination Figure 4 , Figure 5 as well as Figure 6 In a possible implementation, based on the collision information of the vehicle, determining at least one effective ignition level of the vehicle includes: S210, at the first collision A lg0-1 is greater than the first threshold Thr_1, and the second collision degree A lg0-2 is greater than the second threshold Thr_2, and the sixth collision degree A When lg0-6 is greater than the sixth threshold Thr_6, the first ignition level Level_1 of the vehicle is valid.

[0081] S220, at the first collision A lg0-1 is greater than the first threshold Thr_1, and the third collision degree A lg0-3 is greater than the third threshold Thr_3, and the sixth collision degree A When lg0-6 is greater than the sixth threshold Thr_6, the second ignition level Level_2 of the vehicle is effective.

[0082] S230, when the first ignition level Level_1 of the vehicle is valid and the fourth collision degree A When lg0-4 is greater than the fourth threshold Thr_4, the third ignition level Level_3 of the vehicle is effective.

[0083] S240, when the second ignition level Level_2 of the vehicle is effective and the fifth collision degree A When lg0-5 is greater than the fifth threshold Thr_5, the fourth ignition level Level_4 of the vehicle is effective.

[0084] According to the comparison results between the collision degree information and the threshold, the vehicle's ignition level is divided into four effective ignition levels. Different ignition levels correspond to different safety measures, thereby improving the accuracy of vehicle safety measures and improving the increase in maintenance costs and waste of materials caused by unified centralized ignition.

[0085] like Figure 4 and Figure 5 As shown, in a possible implementation, in order to reduce the amount of calculation, a crossing flag can be introduced, and the crossing flag is used to characterize the comparison result between the collision degree and the threshold. When the collision degree is greater than the corresponding threshold, the crossing flag is valid.

[0086] like Figure 4 As shown, the first collision degree A lg0-1 is greater than the first threshold Thr_1, and the first crossing flag Flag_1 is valid. A lg0-2 is greater than the second threshold Thr_2, and the second crossing flag Flag_2 is valid. A lg0-3 is greater than the third threshold Thr_3, and the third crossing flag Flag_3 is valid. A lg0-4 is greater than the fourth threshold Thr_4, and the fourth crossing flag Flag_4 is valid. A lg0-5 is greater than the fifth threshold Thr_5, and the fifth crossing flag Flag_5 is valid. A lg0-6 is greater than the sixth threshold Thr_6, and the sixth crossing flag Flag_6 is valid. When the collision degree is greater than the corresponding threshold, the ignition condition and the non-ignition condition are as follows Figure 5 shown.

[0087] like Figure 6 As shown, when the first crossing flag Flag_1, the second crossing flag Flag_2, and the sixth crossing flag Flag_6 are all valid at the same time, the first ignition level Level_1 is valid. When the first crossing flag Flag_1, the third crossing flag Flag_3, and the sixth crossing flag Flag_6 are all valid at the same time, the second ignition level Level_2 is valid. When the first ignition level Level_1 is valid and the fourth crossing flag Flag_4 is valid, the third ignition level Level_3 is valid. When the second ignition level Level_2 is valid and the fifth crossing flag Flag_5 is valid, the fourth ignition level Level_4 is valid.

[0088] S300, based on at least one valid ignition level, executing at least one corresponding safety measure. Wherein, one ignition level corresponds to one safety measure, and different ignition levels correspond to different safety measures. One safety measure includes: ignition of seat belt pretensioner for the main driver's seat, ignition of seat belt pretensioner for the front passenger's seat, ignition of the airbag for the main driver's seat, or ignition of the airbag for the front passenger's seat.

[0089] One ignition level corresponds to one safety measure, so that different safety measures can be implemented when the vehicle is in different ignition levels. Therefore, the seat belt pretensioner and the airbag ignition can be implemented separately, and the safety measures for the main driver's seat and the front passenger's seat can be implemented separately, thereby improving the accuracy of the safety measures.

[0090] like Figure 6 As shown, in a possible implementation, based on at least one effective ignition level, executing at least one corresponding safety measure includes: Based on the vehicle's first ignition level being effective, the driver's seat seat belt pretensioner ignition is performed.

[0091] Based on the vehicle's second ignition level being active, the front passenger seat seat belt pretensioner ignition is performed.

[0092] Based on the vehicle's third ignition level being valid, the driver's airbag is ignited.

[0093] Based on the vehicle's fourth ignition level being effective, the passenger airbag is ignited.

[0094] In this implementation, different effective ignition levels correspond to different safety measures, thereby achieving time-sharing execution of the airbags for the main driver's seat and the front passenger's seat, which is beneficial to improving the problem of poor accuracy of safety measures caused by unified centralized ignition.

[0095] An embodiment of the present application also provides an ignition device for a vehicle safety measure, comprising: a processing unit. The processing unit is used to obtain collision information of the vehicle. The processing unit is also used to determine at least one effective ignition level of the vehicle based on the collision information of the vehicle. The collision information of the vehicle meets the preset conditions of the effective ignition level. The processing unit is also used to execute at least one corresponding safety measure based on at least one effective ignition level. One ignition level corresponds to one safety measure, and different ignition levels correspond to different safety measures. One safety measure includes: ignition of seat belt pretensioner for the main driver's seat, ignition of seat belt pretensioner for the co-driver's seat, ignition of the airbag for the main driver's seat, or ignition of the airbag for the co-driver's seat.

[0096] In this embodiment, the ignition device of the vehicle safety measure can realize the time-sharing ignition of the main driver's airbag and the co-pilot's airbag, thereby helping to improve the problem of poor accuracy of the safety measure caused by unified centralized ignition.

[0097] In a possible implementation, the ignition device further includes: a first acceleration sensor, a second acceleration sensor, and a third acceleration sensor.

[0098] The first acceleration sensor is installed on the left front part of the vehicle body, for example, the first acceleration sensor is fixedly installed on the vehicle body near or around the left front headlight. For example, the first acceleration sensor is installed on the frame, and the distance from the left front headlight is less than or equal to the set threshold, and the set threshold can be 10-30cm. The second sensor is fixedly installed on the right front part of the vehicle body, for example, the second acceleration sensor is fixedly installed on the vehicle body near or around the right front headlight. For example, the second acceleration sensor is installed on the frame, and the distance from the right front headlight is less than or equal to the set threshold, and the set threshold can be 10-30cm.

[0099] The first acceleration signal is used to characterize the first acceleration. The second acceleration signal is used to characterize the second acceleration. The direction of the first acceleration is parallel to the first direction. The direction of the second acceleration is parallel to the first direction.

[0100] The third acceleration sensor is fixedly mounted on the middle part of the vehicle body. In a possible implementation, the middle part may be within a range of 0-50 cm from the center of the vehicle body. In a possible implementation, the third acceleration sensor is fixedly mounted on the vehicle body and is located in the cab.

[0101] The first sensing direction of the third acceleration sensor is one of its working directions, and the working direction is the direction of acceleration collected when the acceleration sensor is working. Taking the third acceleration sensor as a capacitive acceleration sensor as an example, the first sensing direction can be the direction of movement of the capacitor plate in the capacitive acceleration sensor.

[0102] The first sensing direction of the third acceleration sensor forms an acute angle with the first direction, so that the third acceleration sensor can collect multiple accelerations, and then synthesize the multiple accelerations to obtain the final acceleration, so as to improve the accuracy of the information.

[0103] In a possible implementation manner, an angle between a first sensing direction of the third acceleration sensor and a first direction of the vehicle body is 45 degrees.

[0104] The angle between the first sensing direction of the third acceleration sensor and the first direction of the vehicle body is 45 degrees. After acceleration synthesis, the final angle signal can accurately reflect the collision condition of the vehicle.

[0106] The processing unit is also used to filter the collision acceleration signal of the vehicle.

[0107] The processing unit is also used to perform normalization processing on the collision acceleration signal of the vehicle after filtering processing to obtain the collision acceleration information of the vehicle.

The third acceleration signal is the component of the sum of the first sub-acceleration and the second sub-acceleration in the first direction.
