2 is a diagram showing a configuration of an airbag deployment test system mounted on a vehicle according to an embodiment.

2, the airbag deployment test system 100 may include a sensor 110, an airbag 120, a memory 130, and a controller 140. In addition, the airbag deployment test system 100 may further include a display 200. The display 200 is provided in a cluster or an AVN terminal and connected to the controller 140 through a vehicle communication (for example, CAN communication). However, the display 200 is closely related to the airbag deployment test system 100, Will be described as components of the test system 100. The components and other components may be added or subtracted, but will be omitted for the sake of brevity.

The sensor 110 is disposed on the vehicle front, side, rear, and the like, and can detect a collision of the vehicle. The sensor 110 may include, but is not limited to, an acceleration sensor, a gyroscope sensor, a collision detection sensor, a pressure sensor, and the like. One or more sensors 110 may be mounted on the vehicle.

The airbag 120 is a consumable item developed under the control of the controller 140. When a collision is detected through the sensor 110 when a vehicle collision occurs, the airbag 120 can be operated under the control of the controller 140 .

The memory 130 may store data necessary for driving the airbag deployment test system 100.

The control unit 140 may include an ACU (Airbag Control Unit) having a microcomputer for controlling the entire airbag deployment test system 100.

The controller 140 may be interlocked with the display 200 for driving the airbag deployment test system 100. The display 200 may include a cluster, an AVN terminal, a hindcast display, a HUD (Head Up Display), and the like.

Hereinafter, a driving method of the air bag deployment test system will be described with reference to FIG. The reference numerals of FIG. 2 will be referred to together.

First, the system 100 enters the airbag deployment test mode in the USM (S310).

The User Setting Mode (USM) may be provided in a cluster, but this is only an example and may be provided in another display (e.g., an AVN terminal or a topline display).

At this time, a condition for entering the airbag deployment test mode is inevitably required. System 100 is configured to: i) receive a test mode entry command from the USM switch to the ACU (e.g., Start Comm, Request command); ii) Ig On; iii) the vehicle speed is 0 Kph or RPM is 0; iv) The torque input value is 0, and v) the shift lever position satisfies the P (parking) stage, the airbag deployment test mode entry is performed. The above conditions may be the conditions necessary for the vehicle to proceed safely with the airbag deployment test. However, this is only an example and the airbag deployment test mode entry conditions may be variously configured in advance. For reference, the above condition can be data for setting the development condition for real virtual development after entering the test mode under the condition acquired from the data obtained in the development evaluation (Misuse & evaluation of the roughness).

The system 100 can determine the development when the condition and the actual depression rate and the physical quantity in accordance with the actual collision are inputted into the AU and the expansion condition is satisfied when the system 100 is not normally in the test mode. In addition, when the system 100 is in the test mode, it can be changed to specially set data so that the development conditions can be satisfied even in a slight vibration or a light impact.

Then, when receiving the corresponding signal (for example, a specific CAN ID assignment), the control unit 140 enters the airbag deployment test mode and transmits information to the cluster.

When the cluster receives the information, the system 100 displays the hit area (S320). Will be described with reference to FIG.

According to Fig. 5, the system 100 may display the appearance of the current vehicle, such as a cluster or AVN terminal, and provide the occupant with the location of a sensor for sensing the collision for deployment of the airbag. For example, the system 100 may display the positions of the first to fifth sensors 51 to 55 on the display.

In this case, the occupant may apply an impact to a portion of the actual vehicle corresponding to the hitable portion 51 to 55 displayed on the display. The occupant can impact the actual vehicle with a fist, kicker, rubber hammer, or the like.

At this time, the controller 140 may set the force detection range of the sensor 110 so that the sensor 110 can sense a predetermined small force to prevent damage to the actual vehicle.

The system 100 drives the airbag to be deployed virtually (S340) when a collision occurs in a portion of the vehicle corresponding to the hitting area (S330).

The step S340 will be described in more detail with reference to FIG.

Once the control unit 140 satisfies the preset threshold value in accordance with the physical quantity of the input impact acceleration, the control unit 140 performs the airbag deployment determination. That is, the controller 140 can determine that the airbag has been deployed even if the actual airbag is not deployed.

The control unit 140 normally performs the microcomputer command and recording (S410). The control unit 140 lights the airbag warning lamp. That is, the control unit 140 may transmit a signal indicating that the airbag has been deployed to the cluster or the AVN display to control the airbag warning lamp to be turned on.

At this time, the actual airbag deployment is not generated (S430). The control unit 140 transmits the microcomputer command to the ASIC, but controls the SAFING TR to be unsatisfactory, thereby blocking the current for actual air bag deployment.

For reference, when a microcomputer development command and collision record are generated in the normal mode (normal mode other than the test mode), the information is transmitted to the ASIC and simultaneously developed when the ASIC satisfies the Safing TR. Accordingly, the airbag can actually be deployed. Even if a microcomputer deployment command and collision record are generated in the test mode, when an ASIC is transmitted, a path prohibiting circuit is added or a Safing TR is unsatisfied, the actual deployment signal is not transmitted to the airbag module and the airbag is not deployed.

Next, the system 100 displays the airbag deployment visually / audibly (S440).

Specifically, the system 100 transmits airbag deployment record information (e.g., an ACU 13 message or a Crash Output PWM signal that is sent simultaneously with the ACU deployment signal) to the cluster, and the cluster can provide the deployment status visually and audibly. For example, the system 100 may graphically display the airbag corresponding to the collision site as deployed, and audibly display the airbag as deployed. The BCM (Body Control Management System) can output a simulated sound when the corresponding signal is input to the buzzer lamp or the indoor speaker.

When the deployment simulation is completed, the system 100 ends the airbag deployment test mode (S450). When the end of the test mode is selected in the USM, the control unit 140 ends the test mode.

The system 100 resets the back controller and collectively clears the fault code. In this case, the airbag warning lights displayed in the cluster also flash. When the system 100 receives the ESC and ends the test mode, the ACU senses the signal, clears the DTC, and is reset to operate in the normal mode.

Accordingly, even if the actual airbag is not deployed, the airbag deployment test is performed, so that the user of the vehicle is relieved of the anxiety / suspicion due to unfolding of the airbag, and the user's convenience can be improved.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.

The method according to the above-described embodiments may be implemented as a program to be executed by a computer and stored in a computer-readable recording medium. Examples of the computer-readable recording medium include a ROM, a RAM, a CD- , A floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet).

The computer readable recording medium may be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. And, functional program, code, and code segments for implementing the above-described method can be easily inferred by programmers in the technical field to which the embodiment belongs.
