The present disclosure relates to a digital rear mirror (DRM) device capable of adjusting an angle of view while driving a vehicle and an operating method of the same.
A driver that drives a vehicle needs to keep an eye on the rear while keeping an eye on the front while driving. To this end, the vehicle is equipped with a rear mirror (which may also be referred to as one of rear view mirror, back mirror, room mirror, and inside mirror). That is, the driver verifies the rear through the rear mirror while maintaining the forward-facing posture. However, due to a separate loading box providing a space for a passenger, an object, or a cargo behind the driver, a rear view of the driver is often blocked. This may lead to various risks.
The present disclosure provides a digital rear mirror device capable of adjusting an angle of view while driving a vehicle and an operating method of the same.
In the present disclosure, a digital rear mirror device of a vehicle may include a display module configured to display a rear view video of the vehicle; and a processor configured to connect to the display module and to acquire driving information of the vehicle while driving the vehicle, and to adjust an angle of view for the rear view video based on the driving information.
In the present disclosure, an operating method of a digital rear mirror device of a vehicle may include acquiring driving information of the vehicle while driving the vehicle; adjusting an angle of view for a rear view video of the vehicle based on the driving information; and displaying the rear view video according to the angle of view.
In the present disclosure, a digital rear mirror system of a vehicle may include a camera device configured to capture a rear view video of the vehicle, and a digital rear mirror device configured to acquire driving information of the vehicle while driving the vehicle, to adjust an angle of view for the rear view video based on the driving information, and to display the rear view video according to the angle of view.
In the present disclosure, an operating method of a digital rear mirror system of a vehicle may include acquiring, by the digital rear mirror device, driving information of the vehicle while driving the vehicle, adjusting, by the digital rear mirror device, an angle of view for a rear view video of the vehicle based on the driving information, and receiving, by the digital rear mirror device, the rear view video received from the camera device according to the angle of view.
According to the present disclosure, since a digital rear mirror device displays a rear view video of a vehicle captured by a camera device, an unobstructed rear view may be provided to a driver of the vehicle. In particular, the digital rear mirror device may flexibly adjust an angle of view for the rear view video based on driving information of the vehicle, assisting the driver to safely drive the vehicle when driving the vehicle. That is, the digital rear mirror device may automatically provide the rear view necessary for the driver to drive the vehicle depending on a driving state of the vehicle. For example, the digital rear mirror device may adjust the angle of view when the vehicle changes a speed, changes a lane, or reverses.
Hereinafter, various example embodiments of the present document are described with reference to the accompanying drawings.

According to the fourth example embodiment, the processor 780 may expand the angle of view (F) while the vehicle is reversing, and may reduce the angle of view (F) when the vehicle stops moving backward, for example, when the vehicle moves forward. According to the fifth example embodiment, the processor 780 may move the center of the angle of view (F) downward from the origin when the vehicle is reversing, and may return the center of the angle of view (F) to the origin when the vehicle stops moving backward, for example, when the vehicle moves forward. Other example embodiments are also possible.
In an example embodiment, the processor 780 may update configuration information with the adjusted angle of view (F). In another example embodiment, the processor 780 may control the camera device 110 to capture the rear view video according to the angle of view (F) adjusted through focal distance adjustment. Here, the processor 780 may transmit a control signal of the camera device 110 through the second channel between the serializer of the camera device 110 and the deserializer of the interface module 760. In still another example embodiment, the processor 780 may transmit the adjusted angle of view (F) to the camera device 110, and the camera device 110 may update configuration information with the adjusted angle of view (F). Here, the processor 780 may transmit the adjusted angle of view (F) to the camera device 110 through the second channel between the serializer of the camera device 110 and the deserializer of the interface module 760.

In detail, the processor 780 may be adjusted to operate with the newly determined angle of view (F). That is, the processor 780 may receive the rear view video from the camera device 110 and may acquire driving information of the vehicle while displaying the rear view video at the determined angle of view (F). Then, the processor 780 may maintain or further adjust the determined angle of view (F) based on the driving information.

That is, the digital rear mirror device 120 may automatically provide the rear view necessary for the driver to drive the vehicle depending on a driving state of the vehicle. For example, the digital rear mirror device 120 may adjust the angle of view (F) when the vehicle changes a speed, changes a lane, or reverses. According to an example embodiment, when the digital rear mirror device 120 detects a portion of the rear view video according to the angle of view (F), the camera device 110 may transmit the captured rear view video and thus, a typical camera device may be used without modification. According to another example embodiment, when the camera device 110 is implemented to be capable of adjusting the angle of view through focal length adjustment, the camera device 110 may transmit the captured rear view video as is once set. According to still another example embodiment, when the camera device 110 detects a portion of the rear view video according to the angle of view (F), only the detected portion may be transmitted from the camera device 110 and thus, transmission load between the digital rear mirror device 120 and the camera device 110 may be reduced.

The control device 2100 may include a controller 2120 that includes a memory 2122 and a processor 2124, a sensor 2110, a wireless communication device 2130, a light detection and ranging (LIDAR) device 2140, and a camera module 2150.
The controller 2120 may be configured at a time of manufacture by a manufacturing company of the vehicle or may be additionally configured to perform an autonomous driving function after manufacture. Alternatively, a configuration to continuously perform an additional function by upgrading the controller 2120 configured at the time of manufacture may be included.
The controller 2120 may forward a control signal to the sensor 2110, an engine 2006, a user interface (UI) 2008, the wireless communication device 2130, the LIDAR device 2140, and the camera module 2150 included as other components in the vehicle. Also, although not illustrated, the controller 2120 may forward a control signal to an acceleration device, a braking system, a steering device, or a navigation device associated with driving of the vehicle.
The controller 2120 may control the engine 2006. For example, the controller 2120 may sense a speed limit of a road on which the vehicle 2000 is driving and may control the engine 2006 such that a driving speed may not exceed the speed limit, or may control the engine 2006 to increase the driving speed of the vehicle 2000 within the range of not exceeding the speed limit. Additionally, when sensing modules 2004a, 2004b, 2004c, and 2004d sense an external environment of the vehicle and forward the same to the sensor 2110, the controller 2120 may receive external environment information, may generate a signal for controlling the engine 2006 or a steering device (not shown), and thereby control driving of the vehicle.
When another vehicle or an obstacle is present in front of the vehicle, the controller 2120 may control the engine 2006 or the braking system to decrease the driving speed and may also control a trajectory, a driving route, and a steering angle in addition to the speed. Alternatively, the controller 2120 may generate a necessary control signal according to recognition information of other external environments, such as, for example, a driving lane, a driving signal, etc., of the vehicle, and may control driving of the vehicle.
The controller 2120 may also control driving of the vehicle by communicating with a nearby vehicle or a central server in addition to autonomously generating the control signal and by transmitting an instruction for controlling peripheral devices based on the received information.
Further, if a location or an angle of view of the camera module 2150 is changed, it may be difficult for the controller 2120 to accurately recognize a vehicle or a lane. To prevent this, the controller 2120 may generate a control signal for controlling a calibration of the camera module 2150. Therefore, the controller 2120 may generate a calibration control signal for the camera module 2150 and may continuously maintain a normal mounting location, direction, angle of view, etc., of the camera module 2150 regardless of a change in a mounting location of the camera module 2150 by a vibration or an impact occurring due to a motion of the autonomous vehicle 2000. When prestored information on an initial mounting location, direction, and angle of view of the camera module 2150 differs from information on the initial mounting location, direction, and angle of view of the camera module 2150 that are measured during driving of the autonomous vehicle 2000 by a threshold or more, the controller 2120 may generate a control signal for performing calibration of the camera module 2150.
The controller 2120 may include the memory 2122 and the processor 2124. The processor 2124 may execute software stored in the memory 2122 in response to the control signal of the controller 2120.

Here, the memory 2122 may be stored in a recording medium executable at the non-volatile processor 2124. The memory 2122 may store software and data through an appropriate external device. The memory 2122 may include random access memory (RAM), read only memory (ROM), hard disk, and a memory device connected to a dongle.
The memory 2122 may at least store an operating system (OS), a user application, and executable instructions. The memory 2122 may store application data and arrangement data structures.
The processor 2124 may be a controller, a microcontroller, or a state machine as a microprocessor or an appropriate electronic processor.
The processor 2124 may be configured as a combination of computing devices. The computing device may be configured as a digital signal processor, a microprocessor, or an appropriate combination thereof.

Also, the at least one sensing module 2004 may include an acceleration sensor (2110), a gyroscope, an image sensor (2110), a radar, an ultrasound sensor, a LIDAR sensor, and the like, and may sense motion information of the vehicle 2000.
The sensing module 2004 may receive specific data, such as state information of a road on which the vehicle 2000 is present, nearby vehicle information, and an external environmental state such as weather, as external information, and may sense a vehicle parameter according thereto. The sensed information may be stored in the memory 2122 temporarily or in long-term depending on purposes.
The sensor 2110 may integrate and collect information of the sensing modules 2004 for collecting information generated inside and on outside the vehicle 2000.
The control device 2100 may further include the wireless communication device 2130.
The wireless communication device 2130 is configured to implement wireless communication between the vehicles 2000. For example, the wireless communication device 2130 enables the vehicles 2000 to communicate with a mobile phone of a user, another wireless communication device 2130, another vehicle, a central device (traffic control device), a server, and the like. The wireless communication device 2130 may transmit and receive a wireless signal according to a connection communication protocol. A wireless communication protocol may be WiFi, Bluetooth, Long-Term Evolution (LTE), code division multiple access (CDMA), wideband code division multiple access (WCDMA), and global systems for mobile communications (GSM). However, it is provided as an example only and the wireless communication protocol is not limited thereto.
Also, the vehicle 2000 may implement vehicle-to-vehicle (V2V) communication through the wireless communication device 2130. That is, the wireless communication device 2130 may perform communication with another vehicle and other vehicles on the roads through the V2V communication. The vehicle 2000 may transmit and receive information, such as driving warnings and traffic information, through the V2V communication and may also request another vehicle for information or may receive a request from the other vehicle. For example, the wireless communication device 2130 may perform the V2V communication using a dedicated short-range communication (DSRC) device or a cellular-V2V (CV2V) device. Also, in addition to the V2V communication, vehicle-to-everything (V2X) communication, communication between the vehicle and another object (e.g., electronic device carried by pedestrian), may be implemented through the wireless communication device 2130.
Also, the control device 2100 may include the LIDAR device 2140. The LIDAR device 2140 may detect an object around the vehicle 2000 during an operation, based on data sensed using a LIDAR sensor. The LIDAR device 2140 may transmit detection information to the controller 2120, and the controller 2120 may operate the vehicle 2000 based on the detection information. For example, when the detection information includes a vehicle ahead driving at a low speed, the controller 2120 may instruct the vehicle to decrease a speed through the engine 2006. Alternatively, the controller 2120 may instruct the vehicle to decrease a speed based on a curvature of a curve the vehicle enters.
The control device 2100 may further include the camera module 2150. The controller 2120 may extract object information from an external image captured from the camera module 2150, and may process the extracted object information using the controller 2120.

In addition to the LIDAR device 2140, a radar, a GPS device, a driving distance measurement device (odometry), and other computer vision devices may be used. Such devices may selectively or simultaneously operate depending on necessity, thereby enabling further precise sensing.
The vehicle 2000 may further include the user interface (UI) 2008 for a user input to the control device 2100. The user interface 2008 enables the user to input information through appropriate interaction. For example, the user interface 2008 may be configured as a touchscreen, a keypad, and a control button. The user interface 2008 may transmit an input or an instruction to the controller 2120, and the controller 2120 may perform a vehicle control operation in response to the input or the instruction.
Also, the user interface 2008 may enable communication between an external device of the vehicle 2000 and the vehicle 2000 through the wireless communication device 2130. For example, the user interface 2008 may enable interaction with a mobile phone, a tablet, or other computer devices.
Further, although the example embodiment describes that the vehicle 2000 includes the engine 2006, it is provided as an example only. The vehicle 2000 may include a different type of a propulsion system. For example, the vehicle 2000 may run with electric energy, and may run with hydrogen energy or through a hybrid system with a combination thereof. Therefore, the controller 2120 may include a propulsion mechanism according to the propulsion system of the vehicle 2000 and may provide a control signal according thereto to each component of the propulsion mechanism.
