In addition, the control unit 150 may set a weight based on environment information of the vehicle.

According to an embodiment, the controller 150 may set the weight according to the type of the driving road on which the vehicle is traveling. For example, if it is determined that the vehicle is driving on a general road, the controller 150 may set the weight to 0. Also, when it is determined that the vehicle is traveling on a national road, the controller 150 may set the weight by increasing the weight compared to the case where the vehicle is traveling on a general road. According to an embodiment, when driving on a national road, the weight may be set to +10.

A more detailed description will be given with reference to FIG. 4 .

4 is a diagram illustrating an amount of change in impact corrected by reflecting a weight set according to an environment of a vehicle according to an embodiment of the present invention.

As shown in FIG. 4 , when the driver's disposition is bad and the sensitivity is set to 3, the control unit 150 sets the reference shock variation in each of the X-axis, Y-axis, and Z-axis directions to 50, 50, and 50. can be

For example, the control unit 150 is based on the environmental information of the vehicle, the vehicle is driving on a general road, there is no snow or rain, there is no bump, the road surface condition is also a state without mud, sand, gravel, etc., the road If it is determined that the event information of ' has not been received, the weight may be set to 0, and the reference impact variation corrected for the X-axis direction, the Y-axis direction, and the Z-axis direction may be set to 50, 50, and 50.

As another example, the control unit 150, based on the environmental information of the vehicle, when the vehicle is driving on a general road, snow or rain, and there is a bump on the road ahead, the X-axis direction, the Y-axis direction, and the Z It is possible to set the standard impact change amount corrected for the axial direction as 40, 40, or 70. Refer to Equation 1 for the method of calculating the corrected reference impact change amount.

<Formula 1>

X-axis direction weight = 50 (reference impact change) + 0 (normal road driving)-10 (snow or rain) = 40

Weight in the Y-axis direction = 50 (baseline impact change) + 0 (normal road driving)-10 (snow or rain) = 40

Z-axis weight = 50 (standard impact change) + 0 (normal road driving)-10 (snow or rain) + 30 (bump, Z-axis only) = 70

The controller 150 may set different weights according to the environment information of various vehicles in the above-described manner.

The control unit 150 compares the standard shock change amount corrected by applying the weight set in the above manner with the shock change amount obtained from the sensor 110, and when the shock change amount detected by the sensor 110 exceeds the corrected reference shock change amount Therefore, since the control unit 150 sets the reference shock change amount low in the case of a sensitive driver, it is possible to store the image surrounding the vehicle even when the shock change amount is small. , since the control unit 150 sets the reference shock change amount to be high in the case of the insensitive driver, the image around the vehicle may be stored only when the shock change amount is large.

When it is determined that the vehicle is traveling on a national road or a highway, the controller 150 gives a + weight to the reference shock change amount, so that the image around the vehicle can be stored only when the shock change amount is large.

Also, when the external environment of the vehicle is snow or rain, the control unit 150 gives a - weight to the reference impact change amount, so that even when the impact change amount is small, the image around the vehicle can be stored.

In addition, since the control unit 150 gives + weight when there is a bump or mud, sand, gravel, etc. on the road surface of the road on which the vehicle is traveling, the image around the vehicle is stored only when the amount of change in the impact is large. can

In addition, when event information is received on the road on which the vehicle is driving, the controller 150 gives a weight - so that the image around the vehicle can be stored even when the amount of change in the impact is small.

The controller 150 may set a storage period based on the magnitude of the amount of impact change detected by the sensor 110 and store the surrounding image. According to an embodiment of the present invention, the controller 150 may set the reference value differently when the vehicle is driving and when the vehicle is parked, and may set a storage period corresponding to the reference value. For a more detailed description, refer to FIG. 5 .

5 is a diagram illustrating a storage period set according to an amount of change in impact according to an embodiment of the present invention.

As shown in FIG. 5 , according to the embodiment, when the control unit 150 determines that the amount of shock change detected by the sensor 110 is equal to or greater than the reference value set for each step, the controller 150 stores the surrounding image for a set time corresponding to each reference value. can be controlled to do so. Here, the reference value may be set to a different value when the vehicle is driving and when the vehicle is parked, and as the reference value increases, the storage period may also increase.

For example, if the controller 150 determines that the amount of change in the shock sensed by the sensor 110 is equal to or greater than the first reference value, the controller 150 may store it for 12 hours. Here, the first reference value may be set to 30 when the vehicle is driving, and may be set to 5 when the vehicle is parked. Therefore, the controller 150 may store the surrounding image for 12 hours when the amount of shock change detected by the sensor 110 is 30 or more when the vehicle is driving, and when the vehicle is parked, the sensor 110 detects When the amount of impact change is 5 or more, it is possible to control to store the surrounding image for 12 hours.

As another example, if it is determined that the amount of change in the shock sensed by the sensor is equal to or greater than the fifth reference value (a value greater than the first reference value), the controller 150 may store it for 168 hours. Here, the fifth reference value may be set to 70 when the vehicle is driving, and may be set to 25 when the vehicle is parked. Therefore, when the amount of shock change detected by the sensor 110 is 70 or more when the vehicle is driving, the controller 150 can store the surrounding image for 168 hours, and when the vehicle is parked, the sensor 110 detects When the amount of change of impact is 25 or more, it is possible to control to store the surrounding image for 168 hours.

According to the embodiment of the present invention, as described above, the controller 150 stores the surrounding images for a set time corresponding to each reference value, so that when the amount of change in the shock is relatively large, it can be stored for a long time, and the shock is relatively high. When the change amount is small, it is possible to prevent unnecessary images from being stored for a long time by preventing them from being stored or for a long time.
