Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Collision monitoring apparatus of the vehicle according to the invention is shown in Figure 1, the ignition switch 10, the vehicle speed sensor 20, the front collision detection sensor 30, rear collision detection sensor 40, selection A switch 50, an electronic control module (ECM) 60, a front surveillance camera 70a, and a rear surveillance camera 70b are provided. The ignition switch 10 applies or cuts power to the electrical equipment of the vehicle. The vehicle speed sensor 20 operates as the ignition switch 10 is turned on and the power is applied to detect the speed of the vehicle and apply the corresponding detection signal to the ECM 60 side. The front collision detection sensor 30 operates as the ignition switch 10 is turned on and detects a collision of the front of the vehicle to apply a corresponding detection signal to the ECM 60, and the rear collision detection sensor 40. ) Operates as the ignition switch 10 is turned on and detects a collision in the rear of the vehicle, and applies a corresponding detection signal to the ECM 60 side. The selection switch 50 sets or releases the collision monitoring mode by the driver's selection. The ECM 60 detects whether the ignition switch 10 is turned on or the collision detection mode is set according to the selection switch 50 being turned on from the front collision sensor 30 or the rear collision sensor 40. According to the signal, a control signal corresponding thereto is applied to the front surveillance camera 70a and the rear surveillance camera 70b. The front surveillance camera 70a operates as the control signal is applied from the ECM 60 to record the vehicle speed and the front of the vehicle immediately before the collision, and the rear surveillance camera 70b receives the control signal from the ECM 60. Follow the steps to record the speed of the vehicle and the rear of the vehicle just before the crash.

On the other hand, according to an embodiment of the present invention, the front collision detection sensor 30 is mounted at a predetermined position of the front bumper 80 of the vehicle, as shown in Figure 2a attached, the rear collision detection sensor 40 As shown in FIG. 2B, the rear bumper 90 of the vehicle is mounted at a predetermined position, and the front and rear surveillance cameras 70a and 70b are shown in FIG. 2C. The liner 100 is mounted at a predetermined position before and after the liner 100.

The operation of the present invention configured as described above will be described in detail with reference to the operation flowchart of FIG. 3 as follows.

First, when the vehicle runs, the ECM 60 checks whether the ignition switch 10 is turned on (step S1), and since the vehicle is running, the ignition switch 10 may have been turned on. Accordingly, the ECM 60 detects the vehicle speed according to the detection signal applied from the vehicle speed sensor 20 and stores the vehicle speed (step S2). This means that when the vehicle collides later, the speed of the vehicle immediately before the collision is determined. To record together. Thereafter, the ECM 60 checks whether the collision detection signal is applied from the front collision detection sensor 30 (step S3), and if the collision detection signal is not applied, the ECM 60 detects the rear collision detection sensor 40. In step S4, it is checked whether the collision detection signal is applied. At this time, if the vehicle collided from the rear, the rear collision detection sensor 40 applies a collision detection signal to the ECM 60 side, the ECM 60 recognizes that a collision occurred from the rear, the front surveillance camera 70a and the rear surveillance camera 70b are operated to record the vehicle speed just before the collision and the front and rear of the vehicle (step S5). In addition, when the vehicle collides with the vehicle in front, the collision detection signal is applied from the front collision sensor 30 in step S3, and the ECM 60 recognizes that a collision with the vehicle in front occurs, and monitors the vehicle forward. The camera 70a and the rear surveillance camera 70b are operated to record the vehicle speed just before the collision and the front and rear of the vehicle (step S5).

On the other hand, when the driver finishes driving, turns off the ignition switch 10, turns on the selection switch 50, sets the collision monitoring mode, and then parks the vehicle, the ECM 60 causes the ignition switch 10 to turn on. If it is checked (step S1), since the ignition switch 10 of the vehicle is not turned on, it is checked whether the selection switch 50 is turned on (step S6). At this time, since the selector switch 50 is turned on, the ECM 60 recognizes that the collision monitoring mode is set, and returns to the step S3 to record the situation of the front and rear of the vehicle if a collision occurs even while the vehicle is parked. You can do it.

As described above, the present invention detects a collision accident in the front or rear while driving a vehicle, and records the situation of the front and rear of the vehicle at the time of the accident with a video camera, thereby allowing the parties to be responsible for each other. At the same time, it is possible to eliminate hits caused by transfers and to detect hit-and-run vehicles.
