Hereinafter, the road is used in the sense of highways, national roads, major local roads, one-way or two-way roads where pedestrians go instead of main roads.

Hereinafter, a map-based front camera control apparatus according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4. 2 is a view for explaining a map-based front camera control concept according to an embodiment of the present invention, Figures 3 and 4 are block diagrams for explaining a map-based front camera control apparatus according to an embodiment of the present invention. to be.

As illustrated in FIG. 2, the present invention operates the front camera when the current position (RAE_Cross_Distance) of the vehicle is located at a specific distance (Camera_Display_Distance) from the intersection entry point during the driving of the road based on the driving road information.

The driving road information is obtained through the road type message of the set movement route (link), calculates the intersection entry distance by the forward node distance, and inputs from the front camera by operating the front camera when the driving speed is kept below a certain speed for a certain time. Display the video signal through AVN to indicate the driver to the blind spot. If the driving speed exceeds the specified speed limit, the driver stops the forward camera operation because the driver is not willing to check the blind spot. Let's do it.

Hereinafter, the present invention will be described in more detail in terms of configuration with reference to FIGS. 3 and 4.

As shown in FIG. 3 and FIG. 4, the map-based front camera control apparatus 100 of the present invention includes an information collector 110, a controller 120, and a front camera 200.

The information collecting unit 110 may determine the number of GPS satellites capable of receiving GPS information, whether a route is set, driving road information (type, vehicle, etc.), forward branch information (type, distance), vehicle speed, and route deviation information. Collect and transfer the collected information to the control unit 120.

For example, the information collecting unit 110 collects map information (facility information and distance information to the facility) from the AVN 300, and collects vehicle speed, gear position information, etc. from a transmission control unit (TCU) 400, The driver collects the driver's operation information of the front camera 200 from the CPG 500 and collects GPS data and satellite information corresponding thereto through a GPS receiver.

The first part 120 determines whether to perform a control operation on the front camera 200.

For example, the controller 120 determines whether the GPS information can be received from the GPS satellites, determines whether or not the GPS information is transmitted from the information collecting unit 110, determines whether the delivered GPS information is reliable, and determines the determination result. On the basis of this, it is determined whether the front camera 200 control operation is performed.

That is, the controller 120 may determine whether the GPS information can be received from the GPS satellites based on the GPS satellite information transmitted from the information collector 110, and receive GPS data based on the transmitted GPS satellite information, for example. If the number of GPS satellites is 0, it is determined that the reception of GPS information is impossible. If the GPS information is not transmitted from the information collecting unit 110, it is determined that communication in the vehicle is impossible, and the reliability of the transmitted GPS information is determined. For example, if the number of GPS satellites is at least three or more, it is determined that the received GPS information is reliable.

The control unit 120 determines that it is impossible to receive GPS information from the GPS satellites, fails to receive GPS information from the information collecting unit 110, or is determined to be unreliable in the received GPS information. It is determined that the control operation for 200) is performed.

When it is determined that the controller 120 performs the control operation on the front camera 200, the controller 120 determines whether the driving road of the vehicle is the fine road based on the driving road information transmitted from the information collecting unit 110, and the vehicle is If it is determined that the vehicle runs on the road, it is determined whether the driving speed of the vehicle is less than the preset speed.

For example, the controller 120 determines that the driver has no intention to check the blind spot when the driving speed of the vehicle when the vehicle runs at a fine road is greater than or equal to a preset speed, and stops the control operation on the front camera 200, When the traveling speed is less than the preset speed, the distance from the current position of the vehicle to the intersection entry point is calculated based on the forward branch information transmitted from the information collecting unit 110.

The controller 120 operates the front camera 200 and outputs the image signal input from the front camera 200 through the AVN 300 when the current position of the vehicle is located at a specific distance from the intersection entry point based on the calculated distance. Inform the driver of the situation in front of the blind spot.

When entering the intersection, the control unit 120 stops the control operation on the front camera 200 and prevents the vehicle from being deactivated before and after the vehicle enters the intersection while the vehicle is traveling in the road, so that the vehicle safely passes through the intersection in the road. Do it.

As described above, according to the present invention, it is possible to secure blind spots without distracting the driver's attention (without a separate operation to the front camera), thereby improving the convenience of driving, thereby improving the convenience of blind spots. You can prevent accidents.

Meanwhile, in the present invention, the front camera is controlled based on the information collected through the information collecting unit, but the present invention is not limited thereto. Predict sensor validity, ADAS option setting information, illuminance obstacle vehicle distance, and illuminance obstacle are collected. Control headlamps based on information such as presence and absence of illuminant obstacles, multi-function switch input value, vehicle speed, and illuminance sensor output value (Automatic Head Lamp Control, AHLC), validity of Predict sensor collected through information collector, ADAS option ATSC Setting information, current road type, current link type, current road occupant, distance to next branch node, next branch type, forward branch type, distance between vehicle and forward branch node, link (root) guide code, travel route deviation, Control direction indicator based on information such as multi-function switch input value, vehicle speed, steering wheel sensor input value, heading information, etc. omatic Turn Signal Control (ATSC), the number of GPS receiver satellites collected through the information collection unit, route setting, driving road information (facility), forward facility information (type, distance, etc.), route departure information, vehicle speed, etc. Automatic Ventilation Control (AVC), GPS validity collected through information collector, route setting, angle information / curvature, current road information (type / lane), speed limit information (speed bumps, etc.) Of course, it can be configured to perform a curve warning control (HCW) based on information such as vehicle speed, Accel angle information, and the like.

In the above, the apparatus for controlling a map-based front camera according to an embodiment of the present invention has been described with reference to FIGS. 2 to 4. Hereinafter, the method for controlling a map-based front camera according to an embodiment of the present invention will be described with reference to FIG. 5. Explain. 5 is a flowchart illustrating a map-based front camera control method according to an embodiment of the present invention.

As shown in Figure 5, it is determined whether the vehicle enters the road (S400). For example, when the GPS information cannot be received or the received GPS information is unreliable, it is determined that the control operation for the front camera 200 is performed, and whether the driving road of the vehicle is the fine road based on the transmitted driving road information. Determine whether or not.

As a result of the determination, when the vehicle is driving at the fine road, it is determined whether the vehicle is before entering the intersection (S401). For example, it is determined whether the vehicle is before entering the intersection based on the forward branch information, and if the vehicle is before entering the intersection, it is determined whether the driving speed of the vehicle is less than the predetermined speed (S402).

As a result of the determination, when the driving speed of the vehicle driving at the fine road is greater than or equal to the preset speed, the driver determines that there is no willingness to check blind spots and stops the control operation on the front camera 200.

However, as a result of the determination, when the driving speed of the vehicle driving at the fine road is less than the predetermined speed, the distance from the current position of the vehicle to the entry point of the intersection is calculated based on the forward branch information transmitted, and the calculated current position of the vehicle is the intersection. When located at a specific distance from the entry point to operate the front camera 200 (S402), and outputs the video signal input from the front camera 200 through the AVN 300 to inform the driver of the situation in the front blind spot (S404). ).
