Embodiment 1
[0035] The method of the present invention is based on figure 1 The described architecture is implemented by a perception unit, a control unit and an execution unit respectively, wherein each sensor in the perception unit follows the figure 2 settings shown.
[0036] Such as image 3 As shown, a kind of side airbag implementation method based on multi-parameter decision-making among the present invention concrete steps are as follows:
[0037] The first step is to obtain data through the sensing unit
[0038] Obtain the wheel speed signals of the vehicle through the wheel speed sensor;
[0039] Obtain information about whether there are passengers on the seat through the pressure sensor arranged on the seat cushion;
[0040] Obtain the information of whether the passenger is wearing a seat belt or not through the trigger switch arranged on the seat belt buckle;
[0041] The lateral acceleration of the vehicle is obtained through the acceleration sensor.
[0042] The sec...

The invention discloses an automobile side air bag implementing method based on multi-parameter decision making. The method aims at solving the problem that air bag detonation cannot be accurately controlled through an existing side air bag implementing method conducting detonation decision making based on a single parameter, and through information about the wheel speed of all wheels, the information about whether a passenger exists or not, the information about whether the passenger wears a safety belt or not and the side acceleration of an automobile, air bag detonation control commands output under different degrees of collision strength and different side turning conditions are jointly judged and decided. After receiving the command sent by a control unit, an execution unit executes an air bag execution action. The method is easy to implement by the utilization of existing sensors of the automobile, and the decision making accuracy and reliability are improved through multi-parameter decision making. The strength grade of the side collisions is further taken into consideration in the method, so that air bag denotation is more accurately controlled.
Description
technical field [0001] The invention relates to a method for implementing an automobile side airbag based on multi-parameter decision-making. Background technique [0002] Airbags can effectively protect occupants from or mitigate collision injuries, while side airbags are generally installed on the outside of the seat. Under the action of inertial force, it hits the airbag to avoid direct contact between the torso and the interior parts, and slow down the damage caused by the side impact. [0003] Most of the existing side airbag implementation methods use a single parameter to make the detonation decision, such as the acceleration threshold method and the speed variable method. This decision-making method based on a single parameter cannot accurately control the airbag detonation. An ideal airbag control method includes two meanings: low misexplosion rate and low misexplosion rate. In order to reduce the false deployment rate of the airbag, the current practice is to se...
