The collision monitoring apparatus of the vehicle according to the present invention, as shown in the accompanying drawings, Figure 1, the ignition switch 10, the vehicle speed sensor 20, the front collision detection sensor 30, rear collision detection sensor 40, ECM (Electronic Control Module) 50, a plurality of heat detection sensors 60a to 60n, and a plurality of water pumps 70a to 70n. 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 a corresponding detection signal to the ECM 50 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 50, 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 50 side. When the ignition switch 10 is turned on, the ECM 50 applies a control signal to a plurality of water pumps 70a to 70n when a heat detection signal of a predetermined level or more is applied from the plurality of heat detection sensors 60a to 60n. When the vehicle is traveling at a predetermined speed or more, if a collision detection signal is applied from the front collision detection sensor 30 or the rear collision detection sensor 40, the control signal is applied to the plurality of water pumps 70a to 70n. . The plurality of heat detection sensors 60a to 60n sense heat in the vehicle interior and apply a heat detection signal corresponding thereto to the ECM 50. The plurality of water pumps 70a to 70n operate when a control signal is applied from the ECM 50 to inject water into the vehicle interior.

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 as shown in FIG. 2C, the plurality of thermal sensors 60a to 60n are headliners of the vehicle. 100 is mounted at a predetermined position, and the plurality of water pumps 70a to 70n are mounted at a predetermined position of the water tank formed between the roof 110 of the vehicle and the headliner 100 inside the vehicle interior. In addition, the internal structure of the water pump (70a to 70n) is shown in Figure 3 attached to the bar, when the control signal is applied from the ECM 50, the motor provided in the water pump (70a to 70n) is rotated As it is connected to the pump impeller 71 is rotated at the same time to suck the water stored in the water tank, it is injected through the injection nozzle 72.

Referring to the operation of the present invention configured as described above in detail with reference to the operation flowchart of Figure 4 as follows.

According to an embodiment of the present invention, the temperature inside the vehicle and the speed of the vehicle preset in the ECM 50 are set to 70 ° C. and 50 km / h, respectively.

First, when the vehicle travels, the ECM 50 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 50 detects the vehicle speed according to the detection signal applied from the vehicle speed sensor 20, stores the vehicle speed, and monitors the heat detection signals applied from the plurality of heat detection sensors 60a to 60n. (Step S2). Thereafter, the ECM 50 checks whether the temperature inside the vehicle interior is higher than a predetermined temperature according to the heat detection signals applied from the plurality of thermal sensors 60a to 60n (step S3). If the temperature of the temperature is lower than the predetermined temperature, that is, 70 ° C, the ECM 50 recognizes that no fire has occurred in the vehicle and checks whether the current vehicle traveling speed exceeds the predetermined speed. (Step S4). At this time, if the running speed of the current vehicle does not exceed the preset speed, that is, 50 km / h, the flow returns to the step S1, and if the running speed of the current vehicle exceeds the preset speed, that is, 50 km / h, the ECM 50 checks whether a collision detection signal is applied from the front collision detection sensor 30 and the rear collision detection sensor 40 (step S5). At this time, if the collision detection signal is not applied, the flow returns to the step S1. When the collision detection signal is applied, the ECM 50 injects water into the vehicle interior by operating the plurality of water pumps 70a to 70n. (Step S6). Therefore, even if a fire occurs while the vehicle is running at a high speed while the thermal sensors 60a to 60n are damaged due to a collision accident, the water pump is operated to extinguish the fire.

On the other hand, in step S3, the ECM 50 indicates that a fire has occurred in the interior of the vehicle when the temperature in the interior of the vehicle applied from the plurality of thermal sensors 60a to 60n is higher than a predetermined temperature, that is, 70 °. Upon recognition, the ECM 50 injects water into the vehicle interior by operating the plurality of water pumps 70a to 70n (step S6). Therefore, if a fire occurs due to overheating due to a mistake of the occupant or a poor maintenance of the vehicle while the vehicle is running, the water pump may operate to extinguish the fire.

In addition, the present invention can operate even when the ignition key is removed, that is, the ignition switch 10 is off, it can be set to extinguish the fire when the fire occurs even when the vehicle parking.

As described above, the present invention is to detect the automatic fire if the fire occurs due to overheating due to the passenger's mistake or poor maintenance of the vehicle, or when the fire occurs due to a collision accident from the front or the rear, the automatic By extinguishing the fire quickly by spraying water, it is possible to minimize the casualty caused by the fire of the vehicle.
