[0046] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0048] In the embodiment of the present invention, the operation scenario of the automobile is a car collision test scenario based on environmental perception. The automobile can be a reusable test automobile. It is understandable that in order to reduce costs, the existing technical means are mostly to build an acceleration slide system, and a timed ignition device will be used to ignite the airbag and seat belt. In this way, only the performance of the seat belt and airbag at the specified ignition time can be evaluated, and the performance of the airbag controller cannot be evaluated, resulting in a blank of collision perception of the airbag and seat belt in the actual vehicle environment, and it cannot be verified whether the airbag and seat belt can be normally ignited under specific actual vehicle collision conditions. At the same time, the development of the airbag controller requires a large number of physical sample vehicles to be tested to verify its performance, which is costly and has a long cycle. After the test, the vehicle is scrapped and cannot continue to be tested or used normally, resulting in a large waste of resources.
[0049] Based on this, how to reduce the waste of real vehicles in collision test scenarios, reduce costs and R&D cycles has become a technical problem that needs to be solved urgently.
[0050] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.
[0051] Figure 1 FIG. 1 is a schematic diagram of a vehicle collision test system based on environment perception provided by an embodiment of the present invention. Figure 1 As shown, the system 1 comprises:
[0052] The vehicle platform 10 can move according to a specified acceleration waveform to simulate the collision movement of a real vehicle;
[0053] The vehicle body 11 is mounted on the vehicle platform 10 and includes:
[0054] An airbag 111 and / or a safety belt 112, wherein the airbag 111 and / or the safety belt 112 can be activated based on an ignition electronic pulse signal, wherein the activation of the airbag 111 can form an inflatable buffer zone around the simulated driver in the vehicle body, and the activation of the safety belt 112 can be used to restrict the movement of the simulated driver;
[0055] The external sensor module 113 is used to sense the first acceleration information of the vehicle body 11;
[0056] The signal injector 12 is connected to the external sensor module 113 and is used to receive the first acceleration information of the external sensor module 113 of the vehicle body 11;
[0057] The airbag controller 13 is connected to the signal injector 12 and is used to determine whether the vehicle body 11 is in a collision motion according to the first acceleration information, and output an ignition electronic pulse signal to the airbag and / or the seat belt in response to the vehicle body 11 being in a collision motion;
[0058] The external sensor module 113 is a sensor module installed outside the airbag controller 13 and installed on the vehicle body 11 .
[0059] In some embodiments, in addition to the vehicle body 10, airbag 111, seat belt 112 signal injector 12 and airbag controller 13, the vehicle platform 10 is also equipped with the interior of the vehicle body 10, seats, instrument panel, steering column, steering wheel, battery and corresponding connecting cables, thereby simulating a simulation test vehicle scene similar to a real vehicle, forming a complete test system.
[0060] The vehicle platform 10 here can control the vehicle platform 10 to move according to the specified acceleration waveform by receiving the computer connected to the vehicle platform 10 or the control console of the vehicle platform 10 itself. It can be understood that the acceleration waveform specified here can be the acceleration waveform of different simulated collision scenarios, and the acceleration waveform can be obtained from the cloud big data system. In this way, the vehicle platform 10 can simulate various collision scenarios, so as to test the collision conditions in the vehicle body under different collision scenarios.
[0061] Exemplarily, when a collision begins, the vehicle platform 10 provides a collision start synchronization signal to the signal injector 12 , so that the signal injector 12 obtains the acceleration information of the vehicle platform 10 , which can also be equivalent to the first acceleration information of the vehicle body sensed by the external sensor module 113 .
[0062] The first acceleration information here may include but is not limited to the movement speed, movement direction and movement acceleration of the vehicle body.
[0063] Of course, in order to more accurately simulate the airbag controller 13's perception of the actual vehicle's collision environment, it is necessary to input the corresponding signals collected by each satellite sensor in the external sensor module 113 into the signal injector 12, and then input them into the airbag controller 13. The internal control algorithm of the airbag controller 13 can be used to identify whether it is necessary to detonate the airbag 111 and / or the seat belt 112, thereby simulating the actual vehicle's collision environment.
[0064] Exemplarily, the external sensor module 113 here may include, but is not limited to: a front collision sensor RH and a front collision sensor LH, wherein the front collision sensor RH is a sensor arranged on the right front side of the car, and the front collision sensor LH is a sensor arranged on the left front side of the car.
[0065] In some embodiments, there are multiple signal injectors 12 , and different signal injectors can simulate signals collected by different types of sensors.
[0066] In this embodiment, the airbag controller 13 performs a detonation decision algorithm operation on the signal obtained by the signal injector 12. If the airbag 111 and / or the seat belt 112 need to be detonated, an ignition electronic pulse signal is sent to the airbag 111 and / or the seat belt 112. The detonation decision algorithm here includes, but is not limited to, a comparison algorithm between the movement speed in the first acceleration information and the speed threshold, a comparison algorithm between the movement acceleration in the first acceleration information and the acceleration threshold, etc. After receiving the ignition electronic pulse signal, the airbag 111 and / or the seat belt 112 executes detonation, and the airbag 111 is deployed to form an air bag of a certain volume to protect the simulated driver's head from contacting the airbag 111 and play a buffering role, and the seat belt 112 tightens the simulated driver to avoid a violent collision due to the movement of the vehicle body. In this way, the present embodiment aims to simulate collision scenarios for the airbag controller and also test the airbag controller. Compared with the prior art, in which the development of the airbag controller requires a large number of physical sample vehicles to be tested to verify its performance, the present embodiment can simulate collision scenarios for the airbag controller through the test system and also perform performance tests on the airbag controller, thereby reducing the phenomenon of vehicle scrapping after testing and reducing R&D costs and R&D test cycles.
[0067] In some other embodiments, please refer to Figure 1 The airbag controller 13 is further used to: determine the degree of collision according to the acceleration information in response to the vehicle body 11 being in collision motion; and determine the tightening length of the seat belt 112 according to the degree of collision;
[0068] The safety belt 112 further includes:
[0069] The seat belt tightening device 1121 is used to tighten the seat belt according to the tightening length of the seat belt 112.
[0070] It is understandable that there is a corresponding relationship between the collision degree and the tightening length. Thus, determining the collision degree based on the acceleration information and then testing the tightening length based on the collision degree can facilitate the performance test of the airbag controller 13 on the relationship between the collision degree and the tightening length.
[0071] It should be added that, since some sensors of the external sensor module may be arranged on the periphery of the vehicle body, it is known that during a collision, the periphery of the vehicle body may be damaged, thereby causing damage to the sensors arranged on the periphery of the vehicle body, thereby affecting the signal input to the signal injector, thereby causing the airbag controller to be unable to receive accurate signals. Based on this, in some embodiments, the system further includes:
[0072] A built-in sensor module installed in the airbag controller, used to input the detected second acceleration information to the signal injector and / or the airbag controller;
[0073] The airbag controller is also used to determine whether the vehicle body is in a collision motion based on the first acceleration information and the second acceleration information, and output an ignition electronic pulse signal to the airbag and / or the seat belt in response to the vehicle body being in a collision motion.
[0074] Exemplarily, the airbag controller also has a sensor with motion sensing function, which can sense the movement of the vehicle body and record it in the built-in memory. It also has data computing capabilities, can perform complex algorithm deductions on the obtained sensor data, and execute corresponding output signals according to a pre-set process, such as outputting to a signal injector, or directly outputting to the control module of the airbag controller, or, simultaneously outputting to the signal injector and the airbag controller.
[0075] Thus, in this embodiment, by comprehensively considering whether the vehicle body is in a collision motion through the first acceleration information and the second acceleration information, the airbag and / or seat belt can be ignited more accurately during the collision motion, thereby reducing the mis-ignition of the airbag and / or seat belt and the safety accidents caused by inaccurate judgment caused by only the first acceleration information.
[0076] In some embodiments, the external sensor module and / or the internal sensor module can detect acceleration change information from different directions; the safety airbag includes: a plurality of safety sub-airbags in different directions around the simulated driver safely in the vehicle body;
[0077] The airbag controller is also used to determine the collision direction according to the acceleration change information in different directions; based on the collision direction, output an ignition electronic pulse signal of the safety sub-airbag having the same collision direction; and / or, based on the collision direction, output an ignition electronic pulse signal of the seat belt corresponding to the collision direction.
[0078] For example, see Figure 2 , Figure 2 Another structural diagram of an automobile collision test system based on environment perception provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, the system includes: a left side airbag sensor, a driver airbag module connected to the left side airbag sensor, a front left seatbelt tensioner, and a front left side airbag module; wherein the driver airbag module is used to determine whether to send an ignition electronic pulse signal to the front left side airbag module and / or the front left seatbelt tensioner according to the left side sensing signal detected by the left side airbag sensor, so as to activate the front left side airbag and / or tighten the front left seatbelt; the system also includes: a front right seatbelt tensioner, a right side airbag sensor, a front passenger airbag module connected to the front passenger airbag module, and a front right side airbag module; wherein the front passenger airbag module is used to determine whether to send an ignition electronic pulse signal to the front right side airbag module and / or the front right seatbelt tensioner according to the right side sensing signal detected by the right side airbag sensor, so as to activate the front right side airbag and / or tighten the front right seatbelt.
[0079] Thus, in this embodiment, the collision direction can be determined by the acceleration change information in different directions, so that based on the collision direction, an ignition electronic pulse signal of the safety sub-airbag having the same direction as the collision direction can be output; and / or, based on the collision direction, an ignition electronic pulse signal of the seat belt corresponding to the collision direction can be output; in this way, it can be tested whether the airbag controller can accurately provide protection for the occupants of the vehicle.
[0080] In some embodiments, see Figure 1 and Figure 3 , Figure 3 Another structural diagram of an automobile collision test system based on environment perception provided by an embodiment of the present invention is shown in FIG. Figure 3 As shown, the system also includes:
[0081] The simulated driver 30 is arranged in the vehicle body 11 and includes:
[0082] A human body sensor module 301 is used to detect the injury degree of the simulated driver 30;
[0083] The airbag controller 13 is used to adjust the determination condition for determining whether the vehicle body is in collision motion according to the injury degree of the simulated driver 30 .
[0084] It is understandable that if the injury level of the simulated driver 30 is serious, it indicates that the protection of the airbag and / or seat belt is not sufficient. Thus, by adjusting the conditions for determining whether there is a collision movement, better protection can be provided for the occupants.
[0085] For example, in a collision test, the simulated driver 30 moves under the protection of the airbag 111 and the seat belt 112, and the human body sensor module 301 in the simulated driver 30 can collect corresponding motion data and store it in the vehicle-mounted data acquisition system. After being exported, the injury value of the injury degree is evaluated according to a specific algorithm. Combined with the built-in sensor module with motion sensing function inside the airbag controller, the movement of the vehicle body can be sensed and recorded in the built-in memory. In this way, these test data can be analyzed and processed to improve the control performance of the airbag controller.
[0086] It should be supplemented that the above embodiments may be implemented independently or in any combination, and no limitation is made herein.

[0091] In some optional embodiments, the method further includes:
[0092] Acquire second acceleration information detected by a built-in sensor module in a processor of the vehicle body;
