[0039] The operating principle and embodiments of the disclosed invention will be described below with reference to the attached drawings.

[0040] FIG. 1 illustrates the configuration of a vehicle according to one embodiment.

[0041] As illustrated in FIG. 1, the vehicle (1) includes a driving system (10), a braking system (30), and a steering system (40).

[0042] The drive system (10) moves the vehicle (1) and may include an engine management system (EMS) (11), an engine (12), a transmission control unit (TCU) (21), and a transmission (22).

[0043] The engine (12) includes cylinders and pistons and can generate power for the vehicle (1) to drive. The transmission (22) includes multiple gears and can transmit the power generated by the engine (12) to the wheels.

Additionally, the electronic braking control module (31) can control the braking device (32) to temporarily brake the wheels (Traction Control System, TCS) in response to wheel slip detected during driving of the vehicle (1).

[0049] Additionally, the electronic braking control module (31) can control the braking device (32) in response to a request from the driver assistance device (2). For example, the electronic braking control module (31) can receive a deceleration request including a deceleration rate from the driver assistance device (2) and control the braking device (32) so that the vehicle (1) decelerates based on the requested deceleration rate.

[0050] The steering system (40) may include an Electronic Power Steering Control Module (EPS) (41) and a steering device (40).

[0051] The steering device (42) can change the driving direction of the vehicle (1).

[0052] The electronic steering control module (41) can assist the operation of the steering device (42) in response to the driver's steering intention through the steering wheel so that the driver can easily operate the steering wheel. For example, the electronic steering control module (41) can assist the operation of the steering device (42) to reduce the steering force during low-speed driving or parking and increase the steering force during high-speed driving.

[0053] Additionally, the electronic steering control module (41) can control the steering device (42) in response to a request from the driver assistance device (2). For example, the electronic steering control module (41) can receive a steering request including steering torque from the driver assistance device (2) and control the steering device (42) so that the vehicle (1) is steered in dependence on the requested steering torque.

[0054] The vehicle (1) also includes a Body Control Module (BCM) (51) and a Driver Assistance System (DAS) (2) for the safety and convenience of the driver.

[0055] The body control module (51) can control the operation of electronic components that provide convenience to the driver or ensure the driver's safety. For example, the body control module (51) can control headlamps, wipers, clusters, multifunction switches, and turn signal lamps.

[0056] The driver assistance device (2) can assist the driver in operating (driving, braking, steering) the vehicle (1). For example, the driver assistance device (2) can detect the environment around the vehicle (1) (e.g., other vehicles, pedestrians, cyclists, lanes, road signs, etc.) and control the driving and / or braking and / or steering of the vehicle (1) in response to the detected environment.

[0057] The driver assistance device (2) can provide various functions to the driver. For example, the driver assistance device (2) can provide Lane Departure Warning (LDW), Lane Keeping Assist (LKA), High Beam Assist (HBA), Autonomous Emergency Braking (AEB), Traffic Sign Recognition (TSR), Adaptive Cruise Control (ACC), and Blind Spot Detection (BSD).

[0058] The driver assistance device (2) includes a camera module (101) for acquiring image data around the vehicle (1) and a radar module (102) for acquiring object data around the vehicle (1). The camera module (101) includes a camera (101a) and an Electronic Control Unit (ECU) (101b), and can photograph the front of the vehicle (1) and recognize other vehicles, pedestrians, cyclists, lanes, road signs, etc. The radar module (102) includes a radar (102a) and a controller (102b), and can acquire the relative position, relative speed, etc. of objects around the vehicle (1) (e.g., other vehicles, pedestrians, cyclists, etc.).

[0059] The driver assistance device (2) is not limited to that shown in FIG. 1 and may further include a lidar that scans the area around the vehicle (1) and detects objects.

[0060] The above electronic components can communicate with each other through a vehicle communication network (NT). For example, electronic components can exchange data through Ethernet, MOST (Media Oriented Systems Transport), Flexray, CAN (Controller Area Network), LIN (Local Interconnect Network), etc. For example, a driver assistance device (2) can transmit a driving signal, a braking signal, and a steering signal, respectively, to an engine management system (11), a transmission control unit (21), an electronic braking control module (31), and an electronic steering control module (41) through a vehicle communication network (NT).

[0061] FIG. 2 illustrates the configuration of a driver assistance device according to one embodiment. FIG. 3 illustrates the field of view of a camera and radar included in a driver assistance device according to one embodiment.

[0062] As shown in FIG. 2, the vehicle (1) may include a drive system (10), a braking system (30), a steering system (40), and a driver assistance device (2).

[0063] The driving system (10), the braking system (30), and the steering system (40) may be the same as the driving system (10), the braking system (30), and the steering system (40) shown in FIG. 1.

[0064] The driver assistance device (2) may include a front camera (110), a front radar (120), and a control unit (140).

[0065] FIG. 3 is a control block diagram of a driver assistance device (2) according to one embodiment.

[0066] Referring to FIG. 3, a driver assistance device (2) according to one disclosed embodiment includes an information acquisition unit (100), a control unit (140), and a display unit (400), and may include a sensor unit (200) or a communication unit (300).

[0067] An information acquisition unit (100) according to a disclosed embodiment acquires driver information data.

[0068] The information acquisition unit (100) can acquire driver information based on the driver's facial recognition or the driver's fingerprint recognition. The information acquisition unit (100) may include a sensor or camera for recognizing the driver's face and may include a fingerprint detection sensor for recognizing the driver's fingerprint.

[0069] Additionally, the information acquisition unit (100) can acquire driver information data from card information held by the driver or information stored in the driver's driver's license. To acquire card information or driver's license information data held by the driver, the information acquisition unit (100) may include an IC chip (Integrated Circuit) recognition module or an RFID (Radio-Frequency Identification) recognition module, but is not limited thereto.

[0070] Additionally, the driver's license may include an IC chip, and the driver's identification card that the information acquisition unit (100) can recognize may include a resident registration card or a passport in addition to the driver's license.

[0071] Additionally, the information acquisition unit (100) can generate a storage signal to store data related to the driver in the driver's license and identification card.

[0072] A sensor unit (200) according to a disclosed embodiment may include a first sensor (201) that detects a view object or a second sensor (202) that detects a change in the speed of a vehicle (1).

[0073] Specifically, the first sensor (201) can detect whether a forward object is approaching. Here, the forward object may be a stationary object such as a building, a pillar, a road sign, or another stopped vehicle, but is not limited thereto.

[0074] In addition, the object in front may be a moving object such as another moving vehicle or pedestrian, but is not limited thereto.

[0075] Additionally, the second sensor (202) detects a change in the speed of the vehicle (1). The second sensor can detect whether the vehicle (1) is decelerating or accelerating from the change in the speed of the vehicle (1), and can detect acceleration. Additionally, by detecting the change in the speed of the vehicle (1) in real time, the second sensor can detect the degree of acceleration, the degree of deceleration, the point of acceleration, or the point of deceleration of the vehicle (1).

[0076] A communication unit (300) according to a disclosed embodiment can communicate with a server (3) provided externally regarding driver information data.

[0077] In addition, the communication unit (300) can communicate data regarding the driver's driving tendencies with the server (3).

[0078] The communication unit (300) may include one or more components that enable communication with an external device, and may include, for example, at least one of a short-range communication module, a wired communication module, and a wireless communication module.

[0079] The short-range communication module may include various short-range communication modules that transmit and receive signals using a wireless communication network at short range, such as a Bluetooth module, an infrared communication module, an RFID (Radio Frequency Identification) communication module, a WLAN (Wireless Local Access Network) communication module, an NFC communication module, and a Zigbee communication module.

[0080] Wired communication modules may include various wired communication modules such as Controller Area Network (CAN) communication modules, Local Area Network (LAN) modules, Wide Area Network (WAN) modules, or Value Added Network (VAN) modules, as well as various cable communication modules such as Universal Serial Bus (USB), High Definition Multimedia Interface (HDMI), Digital Visual Interface (DVI), RS-232 (recommended standard 232), power line communication, or plain old telephone service (POTS).

[0081] In addition to Wi-Fi modules and WiBro (Wireless broadband) modules, the wireless communication module may include wireless communication modules that support various wireless communication methods such as GSM (global System for Mobile Communication), CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), UMTS (universal mobile telecommunications system), TDMA (Time Division Multiple Access), and LTE (Long Term Evolution).

[0082] The wireless communication module may include a wireless communication interface comprising an antenna and a transmitter that transmit a signal. Additionally, the wireless communication module may further include a signal conversion module that modulates a digital control signal output from the control unit (140) through the wireless communication interface into an analog wireless signal under the control of the control unit (140).

[0083] The wireless communication module may include a wireless communication interface comprising an antenna and a receiver for receiving a signal. Additionally, the wireless communication module may further include a signal conversion module for demodulating an analog wireless signal received through the wireless communication interface into a digital control signal.

[0084] A display unit (400) according to a disclosed embodiment displays preset driver information.

[0085] Specifically, the pre-configured driver information may be a unique driver number assigned to the driver. The unique driver number may be stored in an identification document such as the driver's driver's license, passport, or national ID card. Additionally, the unique driver number may be stored on a credit or debit card held by the driver.

[0086] The display unit (400) may be provided with a cathode ray tube (CRT), digital light processing (DLP) panel, plasma display panel, liquid crystal display (LCD) panel, electroluminescence (EL) panel, electrophoretic display (EPD) panel, electrochromic display (ECD) panel, light-emitting diode (LED) panel or organic light-emitting diode (OLED) panel, but is not limited thereto.

[0087] A control unit (140) according to a disclosed embodiment determines whether driver information has been changed, and if it is determined that driver information has been changed, controls a display unit (400) to display the unique number of the changed driver.

[0088] Additionally, the control unit (140) can control the display unit (400) to display a unique number assigned to the driver based on information data stored in the driver's identification card, such as a driver's license, passport, or national identification card.

[0089] Additionally, the control unit (140) can control the communication unit (300) to communicate driver information with an external server (3) when driver information data cannot be extracted from the aforementioned identification card or when the driver's unique number cannot be identified.

[0090] Additionally, the control unit (140) can control the information acquisition unit (100) to analyze the driver's driving tendencies and, when the driver finishes driving, store the analysis results in the driver's license. Additionally, the control unit (140) can transmit the driver's driving tendencies to a server (3) provided externally.

[0091] In addition, the control unit (140) can analyze driver information stored in an identification document such as a driver's license and set the driving mode of the vehicle (1) according to the analysis result.

[0092] For example, if the driver set the speed limit to 100 km / h when setting the autonomous driving mode of the vehicle (1) in the previous driving, the control unit (140) can set the speed limit of the vehicle (1) to 100 km / h and control the vehicle (1) to perform autonomous driving.

[0093] In addition, if the driver has set the safety distance to 200m in the previous drive, the control unit (140) can set the vehicle (1) driving mode to a distance of 200m from the vehicle in front.

[0094] However, the criteria for the control unit (140) to set the driving mode of the vehicle (1) are not limited to the driver's past driving, but can be determined based on user definition or the results of an analysis of the driver's driving tendencies. In addition, to set the driving mode, the control unit (140) may determine information related to Smart Cruise Control and apply it to the driving mode setting.

[0095] Additionally, the control unit (140) can set a driving mode of the vehicle (1) based on at least one of the distance to a forward object, the degree of acceleration of the vehicle (1), the degree of deceleration of the vehicle (1), the point of acceleration of the vehicle (1), or the point of deceleration of the vehicle (1), and can control the vehicle so that the vehicle (1) drives autonomously based on the set driving mode.

[0096] In addition, the control unit (140) can control whether the vehicle (1) is driven based on whether the driver is identified.

[0097] Specifically, if the driver is not identified, if the driver is identified as a minor, if the driver is identified as not possessing a license, or if the driver is determined to be a person who is legally restricted from driving, the control unit (140) can control the vehicle (1) so that driving is impossible.

[0098] For example, if the driver is identified as a minor, the control unit (140) can control the vehicle (1) so that the vehicle (1) does not start. However, this is merely one embodiment, and the driving of the vehicle (1) can be restricted by other methods.

[0099] At least one component may be added or removed in response to the performance of the components of the driver assistance device (2) shown in FIG. 3. In addition, it will be readily understood by those skilled in the art that the relative positions of the components may be changed in response to the performance or structure of the system.

[0100] Meanwhile, each component illustrated in Fig. 3 refers to a software and / or hardware component such as a Field Programmable Gate Array (FPGA) and an Application Specific Integrated Circuit (ASIC).

[0101] The following describes in detail the process of the control unit (140) controlling the vehicle (1).

[0102] FIG. 4 is a flowchart showing the process of a control unit (140) according to one embodiment displaying a driver's unique number on a license plate.

[0103] The control unit (140) determines whether the driver is on board the vehicle (1) (1101).

[0104] Specifically, the control unit (140) can determine whether the driver is in the vehicle (1) based on the detection result of the first sensor or the detection result of a passenger detection sensor (not shown) provided in the seat of the vehicle (1).

[0105] When it is determined that a driver is on board the vehicle (1), the control unit (140) obtains driver information data (1102).

[0106] Specifically, the control unit (140) may obtain driver information data based on information stored in the driver's identification card, such as the driver's driver's license, passport, or national identification card, but is not limited thereto.

[0107] When driver information data is obtained, the control unit (140) determines whether the driver information has been changed (1103).

[0108] Specifically, the control unit (140) may determine whether driver information has been changed based on the driver's physical characteristics, such as the driver's face or the driver's fingerprint, but is not limited thereto.

[0109] Additionally, the control unit (140) may determine whether driver information has been changed based on information stored in the driver's identification card, such as the driver's driver's license, passport, or national identification card, but is not limited thereto.

[0110] If it is determined that the driver information has changed, the control unit (140) controls the display unit (400) to display a driver's unique number that is pre-set on the license plate (1104). However, if it is determined that the driver information has not changed, the control unit (140) does not change the display content of the license plate and controls the display unit (400) to display the existing driver's unique number.

[0111] Here, the pre-set unique driver number is assigned differently to each driver and is a number that may be assigned upon issuance of a driver's license, but is not limited thereto. Since the pre-set unique driver number differs for each driver, it is possible to identify the driver by the unique driver number.

[0112] FIG. 5 is a flowchart showing the process of a control unit (140) according to one embodiment acquiring driver information from a driver's license.

[0113] The control unit (140) determines whether the driver has boarded the vehicle (1) (1201).

[0114] When the driver's boarding is detected, the control unit (140) recognizes the driver's driver's license (1202).

[0115] Specifically, the driver's license may contain an IC chip or barcode information, and the control unit (140) can recognize the driver's license based on the IC chip or barcode provided in the driver's license.

[0116] However, the recognition by the control unit (140) is not limited to a driver's license and may include a resident registration card, passport, or credit card.

[0117] If it is determined that an IC chip exists in the driver's license, the control unit (140) controls the display unit (400) to display the driver's unique number on the license plate (1204, 1206).

[0118] However, if it is determined that there is no IC chip in the driver's license or that it is impossible to obtain driver information data from the driver's license, the control unit (140) obtains driver information data from an externally provided server (3) and controls the display unit (400) to display the driver's unique number on the license plate (1205, 1206).

[0119] However, the recognition by the control unit (140) is not limited to a driver's license and may include a resident registration card, passport, or credit card.

[0120] FIG. 6 is a flowchart illustrating that a control unit (140) according to one embodiment stores the driver's driving tendency.

[0121] The control unit (140) analyzes the driver's driving tendencies (1301).

[0122] Here, the driver's driving tendency may include at least one of the degree of acceleration of the vehicle (1), the point of deceleration at which the driver typically begins to decelerate to avoid an object in front, the point of the driver's typical lane change, or the degree of the driver's typical deceleration.

[0123] In addition, the control unit (140) can determine in real time the degree of acceleration of the vehicle (1), the time of deceleration when the driver starts decelerating to avoid an object in front, the time of lane change of the driver, or the degree of deceleration of the driver, statistically analyze, and calculate a normal value.

[0124] When the driver's driving tendency is analyzed and the driving is finished, the control unit (140) determines whether there is an IC chip capable of storing data in the driver's license (1302, 1303).

[0125] If it is determined that there is an IC chip capable of storing data in the driver's license, the control unit (140) generates a storage signal to store the driver's driving tendency information analyzed in the driver's license (1304). When the storage signal is generated, the information acquisition unit (100) can store the driver's driving tendency information in the IC chip provided in the driver's license.

[0126] However, if it is determined that there is no IC chip capable of storing data in the driver's license, the control unit (140) transmits the driver's driving tendency analysis result to a server (3) provided externally (1305).

[0127] As a result, the server (3) or driver's license can store data related to the driver's driving tendencies and can provide information that serves as a basis for arbitrarily setting an autonomous driving mode in the autonomous driving of the vehicle (1).
