[0040] Embodiment 1

[0041] Figure 1 This is a flow chart of a vehicle collision data processing method provided according to the first embodiment of the present invention. This embodiment is applicable to the case where vehicle collision information is uploaded when the vehicle rescue function is used. The method can be executed by a vehicle collision data processing device. The vehicle collision data processing device can be implemented in the form of hardware and / or software. The vehicle collision data processing method device can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0042] The technical solution of this embodiment can be executed by the vehicle control system, which can specifically include the airbag controller, the vehicle controller (T-BOX controller) and the rescue service center, etc. When using the vehicle road life rescue (eCall function), this technical solution can upload some additional information to the MSD, which the rescue center uses to assess the severity of the collision, so as to carry out targeted and efficient rescue.

[0043] Furthermore, the technical solution of this embodiment can be adapted to the European eCall function. In the European market, in addition to meeting basic mandatory regulations, the European New Car Assessment Program (Euro-Ncap) has set higher standards for automobile safety. The rescue and relief part of Euro-Ncap stipulates specific requirements for the eCall function. When a vehicle collides, the T-BOX controller will automatically dial the nearest rescue center and report some necessary information related to the vehicle, collision, and location (MSD) according to certain coding rules. The regulations stipulate the format and coding of MSD. On the basis of this necessary information, Euro-Ncap also requires reporting some additional information to be attached to the MSD, which the rescue center uses to assess the severity of the collision, so as to carry out targeted and efficient rescue. The additional information includes the type of collision event and the maximum lateral and longitudinal speed change of the vehicle within 250ms from the start of the collision.

[0044] S110: When the airbag controller detects a vehicle collision event, a collision start time and a target collision message frame are determined based on the vehicle collision event.

[0045] Among them, the airbag controller can be responsible for collecting, analyzing, judging and processing the collision signal when the vehicle collides, and issuing an ignition command in a timely manner to drive the gas generator to ignite, thereby detonating the airbag to protect the safety of the driver and passengers. Specifically, in this embodiment, the airbag controller can determine whether the vehicle has collided, detect the type of collision, and decide whether it is necessary to ignite certain ignition circuits and provide energy for airbag detonation by collecting the acceleration information and body pressure information of the vehicle. A vehicle collision event can be understood as a situation where the vehicle has collided. The collision start time can be understood as the starting time point of the vehicle collision. The target collision message frame can be understood as a message frame generated when a vehicle collision event occurs. In this embodiment, the target collision message can be understood as an event-type trigger message. The target message frame can include collision type and speed information.

[0046] Furthermore, the airbag electronic control module in this embodiment is equipped with a front collision acceleration sensor, a side collision pressure sensor, and a side collision acceleration sensor, and the airbag controller is also equipped with a five-axis IMU sensor, which can detect the lateral and longitudinal speeds and the rolling angular velocity. Therefore, the airbag controller has the highest accuracy in detecting the collision type and the changes in the lateral and longitudinal accelerations.

[0047] In this embodiment, the vehicle control system can periodically receive signal messages sent by the vehicle. When the airbag controller detects a vehicle collision event, it can trigger the generation of a target collision message frame based on the vehicle collision event, and determine the start time point information of the vehicle collision.

[0048] S120 . Starting from the collision start time, the target collision message frame is sent to the vehicle controller according to a set period until the message frame sending cut-off condition is met.

[0049] Among them, the target collision message frame includes the collision type and real-time speed information. In this embodiment, optionally, the collision type includes front collision, left collision, right collision, rear collision, rollover collision and pedestrian collision. Among them, the front collision can be understood as the collision sent by the front side of the vehicle; the left collision can be understood as the collision on the left side of the vehicle; the right collision can be understood as the collision sent by the right side of the vehicle; the rear collision can be understood as the collision sent by the rear side of the vehicle; the rollover collision can be understood as the vehicle sending a rollover collision; the pedestrian collision can be understood as the collision between the vehicle and the pedestrian. The real-time speed information can be understood as the lateral or longitudinal speed change information between the current time of sending the message and the collision start time. The setting period can be understood as the sending period of the target collision message frame. In this embodiment, the setting period can be pre-set, and for example, the setting period can be 10ms, and can also be set according to actual needs, which is not limited in this embodiment. The vehicle controller can also be called a vehicle networking controller (Telematics Box, T-Box), which can realize the functions of remote monitoring, data acquisition, communication and control of the vehicle by integrating multiple functional modules. The message frame transmission cut-off condition may be a condition for stopping the transmission of the target collision message frame. In this embodiment, the target collision message frame transmission cut-off condition may be that the set period of transmission meets the first set duration, or may be set according to actual needs. For example, the first set duration may be 250ms.

[0050] Specifically, in this embodiment, starting from the moment when the airbag controller determines that the vehicle has reached the threshold of a collision event, that is, the collision start moment, the current real-time target collision message frame is sent to the vehicle controller according to the set period until the first set time is met, and then the sending of the target collision message frame can be stopped.

[0051] In addition, in order to save bus resources and facilitate the T-BOX controller to more easily determine the occurrence of a collision event, the target collision message can be defined as an event type. This message is sent only when a collision occurs, and can remain silent at other times.

[0052] In this embodiment, optionally, the message frame sending cut-off condition includes a first set time period after the collision start time, or a set number of target collision message frames.

[0053] The first set duration may be pre-set time information. For example, the first set duration in this embodiment may be 250 ms, and may also be set according to actual needs, which is not limited in this embodiment. The set quantity may be understood as the number of target message frames to be sent. For example, the set quantity may be 25 frames, or 30 frames, etc., which may be set according to actual needs, which is not limited in this embodiment.

[0054] Through such a setting in this embodiment, the real-time target collision message frame that can be sent can be limited to a sending cutoff condition, and the collision type and speed information within the required time can be sent according to the actual needs of the user, so that the actual situation of the current collision can be clearly understood based on the target collision message frame that occurs, which is more convenient and flexible.

[0055] In this embodiment, optionally, starting from the start time of the collision, the target collision message frame is sent to the vehicle controller according to a set period until the message frame sending cut-off condition is met, including: starting from the start time of the collision, one frame of the target collision message is sent to the vehicle controller every set period until the number of target collision messages sent meets the set number.

[0056] In this embodiment, starting from the collision start time, a target collision message frame containing collision type and speed information may be sent to the vehicle controller at set intervals until the number of sent target collision message frames meets the set number requirement.

[0057] Exemplarily, the moment when the airbag controller determines that the vehicle has reached the threshold of a collision event is taken as the collision start moment (T0), and a target collision message frame including collision type and speed information is sent every set period of 10ms until the number of target collision message frames sent reaches 25 frames, that is, the sending period reaches 250ms, and then the sending of target collision message frames to the T-BOX can be stopped.

[0058] Through such a setting in the present embodiment, the sending cut-off condition can be limited according to the number of real-time target collision message frames sent, so that when the sent target collision message frames reach the set number, the sending of target collision message frames can be stopped. This not only facilitates the clear understanding of the actual situation of the vehicle collision based on the target collision message frames that occur, but also avoids the situation where resources are wasted by sending messages continuously, thereby saving system resources.

[0059] S130: Report the received collision type and real-time speed information to a rescue service center through the vehicle-mounted controller.

[0060] Among them, the rescue service center can also be called the eCall function. When a vehicle is involved in a traffic accident and needs rescue, the alarm can be triggered by pressing a button on the on-board device, or the alarm will be automatically triggered in the event of a severe collision. The on-board controller will automatically upload key accident information, including time, location, weather, vehicle information, etc., to increase the rescue speed.

[0061] In addition to automatically uploading key accident information by the on-board controller, the present embodiment also generates a target collision message frame through the airbag controller and sends it to the on-board controller. The on-board controller reports the received target collision message frame containing the collision type and real-time speed information to the rescue service center, so that the rescue service center can evaluate the severity of the current collision and carry out targeted and efficient rescue.

[0062] Exemplarily, the airbag controller adds an outgoing target collision message frame, and the set sending period can be 10ms. The message contains the collision type and the lateral and longitudinal speed change values. The T-BOX controller receives this group of messages from the bus and decodes the information, and reports it to the MSD of the rescue service center.

[0063] The technical solution of the embodiment of the present invention is that when the airbag controller detects a vehicle collision event, the collision start time and the target collision message frame are determined based on the vehicle collision event; starting from the collision start time, the target collision message frame is sent to the vehicle controller according to a set period until the message frame sending cut-off condition is met; wherein the target collision message frame includes the collision type and real-time speed information; and the received collision type and real-time speed information are reported to the rescue service center through the vehicle controller. This technical solution can report the collision type and real-time speed information to the rescue service center to evaluate the severity of the collision, thereby conducting targeted and efficient rescue.

[0064] Embodiment 2

[0065] Figure 2It is a flow chart of a vehicle collision data processing method provided according to the second embodiment of the present invention. This embodiment is optimized based on the above embodiment. The specific optimization is as follows: the real-time speed information includes the real-time speed change; starting from the collision start time, the target collision message frame is sent to the vehicle controller according to the set period until the message frame sending cut-off condition is met, and it also includes: comparing the real-time speed change in the sent target collision message frame to obtain the maximum speed change; using the maximum speed change as a new collision message frame and sending it to the vehicle controller. Figure 2 As shown, the method includes:

[0066] S210: When the airbag controller detects a vehicle collision event, a collision start time and a target collision message frame are determined based on the vehicle collision event.

[0067] In this embodiment, optionally, determining the collision start time based on the vehicle collision event includes: obtaining the speed change within a second set time period within the vehicle collision event; determining whether the speed change is greater than a set threshold; if the speed change is greater than the set threshold, taking the time corresponding to the speed change as the collision start time.

[0068] The second set duration can be understood as the set duration information within the collision time. In this embodiment, the second set duration can be 20ms, and can also be set according to actual needs. The set threshold can be pre-set. In this embodiment, the set threshold corresponding to the speed change value can be different according to different collision types.

[0069] In this embodiment, if the airbag controller detects a vehicle collision event, it can obtain the speed change of 20ms within the vehicle collision event, and determine whether the speed change of 20ms is greater than the set threshold. If the speed change of 20ms is greater than the set threshold, the moment corresponding to the speed change can be used as the start time of the collision.

[0070] For example, if the collision type is a frontal collision or a rearward collision, the second set time length can be 20ms. Within the 20ms time interval, the moment when the longitudinal cumulative speed change value is greater than the set threshold value of 0.8km / h can be used as the collision start time, or within the second set time length of 5ms for a side collision event, the moment when the lateral cumulative speed change value is greater than 0.8km / h can be used as the collision start time.

[0071] Through such a setting in this embodiment, the speed change amount corresponding to different durations of the collision type can be compared with the corresponding set threshold to determine the collision start time, which is more accurate and reliable.

[0072] S220: Starting from the collision start time, the target collision message frame is sent to the vehicle controller according to the set period until the message frame sending end condition is met.

[0073] Among them, the target collision message frame includes the collision type and real-time speed information; the real-time speed information includes the real-time speed change; the real-time speed change can be understood as the difference data between the real-time speed corresponding to the current real-time moment and the lateral and / or longitudinal speed corresponding to the collision start moment.

[0074] S230: Compare the real-time speed changes in the sent target collision message frames to obtain a maximum speed change.

[0075] The maximum speed variation may be the maximum speed difference data among all target collision message frames sent by the airbag controller.

[0076] In this embodiment, the airbag controller can compare the real-time changes in all the sent target collision message frames to obtain the maximum speed change value in the target collision message frame.

[0077] S240: Use the maximum speed change as a newly added collision message frame and send it to the vehicle controller.

[0078] The newly added collision message frame can be understood as an additional message frame in addition to the sent target collision message frame. In this embodiment, the maximum speed change obtained by comparing the real-time changes in all target collision message frames can be used as the newly added collision message frame and sent to the T-BOX controller.

[0079] Specifically, in this embodiment, within a short period of time after the collision event occurs, after the T-BOX controller receives the information about the collision event, it needs to confirm the vehicle position, collect information in the MSD, and call for help in a short period of time. It may not have the resources to compare the lateral and longitudinal speed changes and select the largest lateral and longitudinal speed changes. Therefore, in this embodiment, after the airbag controller sends 25 frames of target collision message frames, it is necessary to add a frame of message information to select the maximum speed change in the 25 frames and send it to the T-BOX controller, so that if the T-BOX has computing resources, it can compare and select by itself, or it can directly upload the received newly added collision message frames to the MSD. This saves the computing resources of the MSD and increases the success rate of correctly uploaded information.

[0080] S250: Report the received collision type and real-time speed information to a rescue service center through the vehicle-mounted controller.

[0081] In this embodiment, the airbag control unit is used as the detection subject for detecting collision information, which can ensure the accuracy of the information to the greatest extent; the target collision message is an event-triggered message of the airbag controller, which will be sent out only when a collision occurs, which not only saves communication resources on the entire vehicle, but also ensures that the T-box can accurately identify the starting point of the collision information; and a unique design is made on the signal of the lateral and longitudinal speed change. After the 250ms specified by Euro-Ncap from the collision starting point, another frame of information is added to filter out the maximum change and send it to T-BOX, saving the computing resources of T-BOX. Therefore, through the technical solution of this embodiment, the requirements of Euro-Ncap for the eCall function to upload additional MSD information can be achieved with minimal resources, and the accuracy of this information can be guaranteed.

[0082] The technical solution of the embodiment of the present invention is as follows: when the airbag controller detects a vehicle collision event, the collision start time and the target collision message frame are determined based on the vehicle collision event; starting from the collision start time, the target collision message frame is sent to the on-board controller according to the set period until the message frame sending cut-off condition is met; wherein the target collision message frame includes the collision type and real-time speed information; the real-time speed change in the sent target collision message frame is compared to obtain the maximum speed change; the maximum speed change is used as a new collision message frame and sent to the on-board controller. The received collision type and real-time speed information are reported to the rescue service center by the on-board controller. This technical solution can report the collision type and real-time speed information to the rescue service center to evaluate the severity of the collision, thereby performing targeted and efficient rescue.
