CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of priority to Korean Patent Application No. 10-2019-0084431, filed in the Korean Intellectual Property Office on Jul. 12, 2019, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to an apparatus for recording an image of a vehicle, a system having the same, and a method thereof, and more particularly, relates to a vehicle image recording technology for performing exception handling of an impact detected when a door of a vehicle is opened or closed.

BACKGROUND

In general, a vehicle image recording apparatus (a black box) includes one or more cameras for taking images of surroundings of a vehicle. The vehicle image recording apparatus detects a direction (e.g., a fore/aft, left/right, or up/down direction) in which an impact is applied to the vehicle, based on a measurement value of an impact sensor (a 3-axis G-sensor) according to the impact applied to the vehicle and detects a portion of the vehicle to which the impact is applied, based on an image taken with a camera located in the impact direction of the vehicle.

The vehicle image recording apparatus in the related art often takes and records an image by misidentifying an impact occurring when a door, a hood, or a trunk is opened or closed under a normal vehicle usage condition, as an impact caused by an accident.

Due to the unnecessary photographing and recording caused by the misidentification, power and memory may be unnecessarily consumed.

SUMMARY

The present disclosure has been made to solve the above-mentioned problems occurring in the prior art while advantages achieved by the prior art are maintained intact.

An aspect of the present disclosure provides an apparatus for recording an image of a vehicle, a system having the same, and a method thereof, in which the apparatus is aimed at preventing erroneous or unnecessary recording by performing exception handling of unnecessary impacts, such as impacts imposed on the vehicle when doors (e.g., a door, a hood, a trunk, a tailgate, and the like) of the vehicle are opened or closed, in conjunction with an in-vehicle communication network.

The technical problems to be solved by the present disclosure are not limited to the aforementioned problems, and any other technical problems not mentioned herein will be clearly understood from the following description by those skilled in the art to which the present disclosure pertains.

According to an aspect of the present disclosure, an apparatus for recording an image of a vehicle includes: a processor that determines whether an impact of a reference value or more applied to the vehicle is caused by an accident, by using a signal of an in-vehicle communication network and performs control to not record a vehicle image for a predetermined exception handling time, when the processor determines that the impact is not caused by the accident; and a storage controlled by the processor to record the vehicle image.

The processor may determine a transition of a Controller Area Network (CAN) communication signal of the in-vehicle communication network for a predetermined period of time after the occurrence of the impact and may determine that the impact is caused by the accident, when the transition of the CAN communication signal does not occur.

The processor may set the predetermined exception handling time in advance by setting, as a margin, maximum time during which an aftershock occurs after the first impact.

The processor may monitor a transition of a CAN communication signal of the in-vehicle communication network for predetermined monitoring time after the occurrence of the impact.

The processor may set the sum of a maximum period of the communication signal and maximum latency as the monitoring time in advance.

A CAN communication signal of the in-vehicle communication network may include at least one of open/close signals of doors, an open/close signal of a trunk, an open/close signal of a hood, or an open/close signal of a tailgate.

According to another aspect of the present disclosure, a vehicle system includes: a sensing device that senses an impulse of a vehicle; and a vehicle image recording apparatus that determines whether an impact is caused by an accident by using a signal of an in-vehicle communication network when the impulse of the vehicle received from the sensing device is greater than or equal to a reference value, and that performs control to not record a vehicle image for a predetermined exception handling time when the vehicle image recording apparatus determines that the impact is not caused by the accident.

The vehicle image recording apparatus may determine a transition of a Controller Area Network (CAN) communication signal of the in-vehicle communication network for a predetermined period of time after the occurrence of the impact and may determine that the impact is caused by the accident, when the transition of the CAN communication signal does not occur.

The vehicle image recording apparatus may set the predetermined exception handling time in advance by setting, as a margin, maximum time during which an aftershock occurs after the first impact.

The vehicle image recording apparatus may monitor a transition of a CAN communication signal of the in-vehicle communication network for predetermined monitoring time after the occurrence of the impact.

The vehicle image recording apparatus may set the sum of a maximum period of the communication signal and maximum latency as the monitoring time in advance.

According to another aspect of the present disclosure, a method for recording an image of a vehicle includes: determining whether an impact of a reference value or more is applied to the vehicle; determining whether the impact is caused by an accident by using a signal of an in-vehicle communication network when it is determined that the impact of the reference value or more is applied to the vehicle; and performing control to not record a vehicle image for a predetermined exception handling time when it is determined that the impact is not caused by the accident.

A Controller Area Network (CAN) communication signal of the in-vehicle communication network may include at least one of open/close signals of doors, an open/close signal of a trunk, an open/close signal of a hood, or an open/close signal of a tailgate.

The method may further include setting the predetermined exception handling time in advance by setting, as a margin, maximum time during which an aftershock occurs after the first impact.

The method may further include monitoring a transition of a CAN communication signal of the in-vehicle communication network for predetermined monitoring time after the occurrence of the impact.

The method may further include setting the sum of a maximum period of the communication signal and maximum latency as the monitoring time in advance.
