Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] Airbag controller impact strength test and airbag controller ignition algorithm verification test

[0040]1) The impact strength test of the airbag controller In this specific embodiment, the test block (13) is adjusted to the end of the slideway (12), and the energy-absorbing tube fixing seat (22) is removed, and the newly developed safety The airbag controller (31) is fixed on the tail of the tackle (13) by bolts, and the acceleration direction collected by the controller (31) is confirmed to be consistent with the acceleration direction of the collision, and the sensor (32) of the data acquisition instrument is installed on the boss of the tackle (22) , used to collect the acceleration of the tackle (13), so as to be used for comparative analysis with the acceleration signal collected by the controller (31). Use the hand-held electro...

Abstract

The invention discloses an ignition algorithm verification test device for an air bag restraint system controller, which can replace a trolley test for verification of impact strength and ignition algorithm of the air bag restraint system controller in early stage of development of the air bag restraint system controller. The test device comprises four modules, including a test stand rack, a pendulum bob impact acceleration mechanism, a test pulley component and a data acquiring module; the test stand rack comprises a main test stand rack, a pulley slide way and a pulley buffering device; the test stand rack acts as a component for bearing load in the test; the pendulum bob impact acceleration mechanism comprises a handheld electromagnet, a pendulum bob, a pendulum rod vernier device, a pendulum rod and an oscillation angle measurer; the pendulum bob impact acceleration mechanism acts as a power output component in the test; the test pulley component comprises a pulley, an energy absorption cylinder fixing seat and an energy absorption cylinder; the test pulley component acts as an automobile for simulating impact and a carrier of an air bag restraint system controller sample; and the data acquiring module comprises an acceleration sensor and a speed measurer and is used for acquiring the test data in the test. The algorithm verification test device disclosed by the invention has the advantages of simple structure, low cost, convenience in operation and high efficiency, etc.

Description

technical field [0001] The invention mainly relates to the verification test field of algorithms in the development of safety airbag controllers, in particular to a test device for quickly verifying newly developed automobile safety airbag controllers and algorithms. Background technique [0002] The occupant restraint system is one of the most important automotive passive safety devices, and its reliability is related to the life safety of occupants in collision accidents. When a car collides, at first the car collides with an external obstacle. Then, under the action of inertial force, the passenger will have a secondary collision with the car interior parts. As an important part of the restraint system, the airbag is used to form an air bag to restrict the occupant to move forward after a car collision, reducing the risk of collision between the occupant and the interior parts of the car, thereby reducing the injury suffered by the occupant in the accident . Therefore,...
