Problems solved by technology
Because some devices of the airbag electronic control system are being reset at this time (that is, during the collision), the airbag may not be deployed correctly, and the driver and occupants in the car may not be protected during the collision.
[0006] Taking a step back, even if the reset occurs when the actual collision is about to occur, it may prevent the airbag electronic control system from making correct judgments and timely preparations
Therefore, the airbag may not be deployed correctly, and there is also a potential risk

Embodiment Construction
[0024] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and multiple embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, rather than to limit the protection scope of the present invention.
[0025] figure 1 A system block diagram of an airbag electronic control system according to an exemplary embodiment of the present invention is shown.
[0026] Such as figure 1 As shown, the airbag electronic control system 1 includes the following basic functional components: a microprocessor 2 for data processing and control operations, a sensor 3 for detecting collisions, and an ignition drive module 5 for igniting the airbag assembly 4 (It can also be integrated in the microprocessor 2). The sensor 3 is conne...

The invention discloses a safety airbag electronic control system, a related safety airbag system and an automobile. The safety airbag electronic control system comprises a micro-processor, a sensor detecting collision, a system reset module at least resetting the micro-processor when the micro-processor acts abnormal, and a reset limiting module forbidding the system reset module to execute reset operation upon collision and during the collision. The sensor is connected the micro-processor and sends a detection signal to the micro-processor for analysis. The invention further discloses a safety airbag system containing the safety airbag electronic control system, and an automobile including the safety airbag system. According to the safety airbag electronic control system, correct expansion of the safety airbag cannot be affected by system reset during the collision due to the reset limiting module, so great protection is provided for drivers and passengers.
Description
technical field [0001] The invention relates to an electronic control system of a safety airbag, a corresponding safety airbag system and an automobile. Background technique [0002] Today, with the widespread use of automobiles, automobile safety is getting more and more attention. As a passive safety protection system, the airbag system has been fully and effectively verified for the safety protection of the driver and passengers in the event of an accident. At present, with the wide application of airbag system in automobiles, the electronic control system of airbag has experienced the improvement process from mechanical control, simple electronic control to intelligent control. [0003] When a car collides while driving, the airbag sensor first receives the crash signal (such as an acceleration signal) and transmits the signal to the microprocessor. After the microprocessor receives the signal, it compares it with a predetermined threshold, and if the airbag deployment...
