20250187622
This application claims the benefit of and priority to Korean Patent Application No. 10-2023-0180177, filed in the Korean Intellectual Property Office on Dec. 12, 2023, the entire contents of which are hereby incorporated herein by reference.
The present disclosure relates to a method for providing driving mode information and a device using the same.
Conventionally, to reduce a risk of an occurrence of a large-scale traffic accident, if a driver of a vehicle in which an autonomous driving system does not operate performs other actions while driving (for example, if the driver watches TV or plays a game while driving), police imposed a penalty, such as a fine, on the driver. On the other hand, in principle, a passenger in a driver's seat of a vehicle with the autonomous driving system operating at a certain level (e.g., a level 3) or higher is free to perform actions other than driving.
Therefore, to regulate the driver who performs actions other than driving in the vehicle in which the autonomous driving system is not operating, it is necessary to accurately provide the police with information on whether the vehicle is currently traveling in an autonomous driving mode.
As one of methods for providing such information, a method of indicating whether the autonomous driving mode is activated via an indicator light mounted on the vehicle is being discussed. However, if such a method is used, information on whether the autonomous driving mode is activated may also be provided to a third party other than the police. In some cases, other drivers around a host vehicle may intentionally interfere with autonomous driving of the host vehicle.
Therefore, a method for effectively transmitting the information on whether the traveling vehicle is traveling in the autonomous driving mode is desired.
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.
Aspects of the present disclosure provide a method for providing driving mode information of a traveling vehicle and a device using the same.

Various embodiments of the present disclosure are described below with reference to the accompanying drawings. However, the present disclosure is not intended to limit the technology described herein to the specific embodiments. Rather, the present disclosure should be understood to include various modifications, equivalents, and/or alternatives of the described embodiments. In connection with the description of the accompanying drawings, like reference numerals may be used for like components.
In describing the components of the embodiments according to the present disclosure, terms such as first, second, A, B, (a), (b), and the like may be used. These terms are merely intended to distinguish the components from other components. The terms do not limit the nature, order, or sequence of the components.

Hereinafter, embodiments of the present disclosure are described in detail with reference to
Referring to
The monitoring terminal outside the host vehicle may be a terminal of police that regulates violation of traffic regulations, for example.
The real-time driving mode information requested by the monitoring terminal may include current autonomous driving level information of the host vehicle. In an embodiment, autonomous driving levels may be classified for convenience into a level 0 (no automation), a level 1 (driver assistance), a level 2 (partial automation), a level 3 (conditional automation), a level 4 (high automation), and a level 5 (full automation).
As another example, the real-time driving mode information requested by the monitoring terminal may include the current autonomous driving level information of the host vehicle and information on a function corresponding thereto.
As another example, the real-time driving mode information requested by the monitoring terminal may include the current autonomous driving level information of the host vehicle, the information on the function corresponding thereto, and information on actions allowed for a driver.
In an example, if the request for the real-time driving mode information is acquired from the monitoring terminal, the device for providing the real-time driving mode information may verify the monitoring terminal by referring to (e.g., based on) authentication information contained in the request for the real-time driving mode information.
For example, if a request containing an authentication number is acquired from the monitoring terminal of the police that regulates the violation of the traffic regulations, the device for providing the real-time driving mode information may transmit the corresponding authentication number to a National Police Agency server and allow the National Police Agency server to check validity of the authentication number. Further, if the authentication number is checked to be valid by the National Police Agency server, the device for providing the real-time driving mode information may determine (e.g., verify) that the monitoring terminal requesting the real-time driving mode information is a valid monitoring terminal.
If the request for the real-time driving mode information of the host vehicle is acquired in operation S110, the device for providing the real-time driving mode information may, in an operation S120, check the real-time driving mode information corresponding to the host vehicle.
For example, the device for providing the real-time driving mode information may check a current autonomous driving level corresponding to the host vehicle and may transmit a query to a database to check i) a function in operation corresponding to the current autonomous driving level and ii) information on actions allowed for the driver while the corresponding function is in operation. As described in more detail below, the database may be checked by the host vehicle. However, the present disclosure is not limited thereto. For example, the database may be checked by the monitoring terminal.
In an embodiment, the database may be a remote server located outside the host vehicle. However, the present disclosure is not limited thereto. For example, the database may be mounted inside the host vehicle. Additionally, the database may be updated periodically and/or aperiodically. For example, if the database is mounted inside the host vehicle, the database may be updated via wired communication or wireless communication (e.g., over-the-air (OTA)).
For example, if the current autonomous driving level corresponding to the host vehicle is checked to be 1, the device for providing the real-time driving mode information may transmit the query to the database to check a function (e.g., a lane following assist (LFA)) corresponding to a current autonomous driving level 1 and information on actions allowed for the driver in the corresponding function (e.g., a maximum time hands are allowed to be off a steering wheel).
Table 1 shows example data stored in the database. For reference, for convenience, Table 1 only describes a specific autonomous driving level (the level 1) and a specific function (the LFA). However, the present disclosure is not limited thereto.
Referring still to
In various embodiments, the driver state information may be acquired via various systems mounted inside the host vehicle.
For example, information on whether the driver is currently drowsy or the like may be acquired via a driver drowsiness and attention warning system (DDAW).
Additionally, the driver action conditions corresponding to the real-time driving mode information may be conditions for actions allowed for the driver in the specific function in operation at the specific autonomous driving level.
For example, while the host vehicle is currently traveling at the autonomous driving level 1 and the lane following assist function corresponding to the autonomous driving level 1 is in operation, if the driver is currently playing a game in a driver's seat, is not looking ahead, is drowsy, or keeps taking the hands off the steering wheel, the driver action conditions are not satisfied, as may be seen in Table 1. In this case, the device for providing the real-time driving mode information may determine that the driver action conditions corresponding to the real-time driving mode information are not satisfied by referring to (e.g., based on) the driver state information of the host vehicle.
If it is determined that the driver action conditions are not satisfied, the device for providing the real-time driving mode information may request a specific driver action to satisfy the driver action conditions to the driver of the host vehicle.
For example, if the driver keeps taking hands off the steering wheel, a vibration sensor mounted on the steering wheel may be activated, an alarming sound may be output via a speaker, or a warning message may be output to the driver via a display screen to encourage the driver to grip the steering wheel.
As another example, if the driver is not looking ahead, the alarming sound may be output via a speaker or the warning message may be output to the driver via a display screen to encourage the driver to look ahead.
In an embodiment, the device for providing the real-time driving mode information may determine whether the number of requests to the driver of the host vehicle for the specific driver action to satisfy the driver action conditions is smaller than a threshold number before making the request to the driver.
If the number of requests is smaller than the threshold number, the device for providing the real-time driving mode information may repeat the process of requesting the specific driver action to the driver of the host vehicle and then determining whether the driver action conditions are satisfied.
If whether the driver action conditions are satisfied is determined based on the operation S130, the device for providing the real-time driving mode information may, in an operation S140, provide at least some of the real-time driving mode information to the monitoring terminal by referring to (e.g., based on) the determination result.
For example, the device for providing the real-time driving mode information may provide at least some of the real-time driving mode information to the monitoring terminal based on a vehicle-to-everything (V2X) communication.
In an example, if it is determined that driver action conditions are satisfied, the device for providing the real-time driving mode information may provide at least some of the real-time driving mode information to the monitoring terminal.
In an embodiment, the device for providing the real-time driving mode information may provide at least some of the real-time driving mode information to the monitoring terminal by additionally referring to the result of requesting the specific driver action to the driver.
For example, when the device for providing the real-time driving mode information has repeatedly requested the specific driver action to satisfy the driver action conditions to the driver of the host vehicle the threshold number (e.g., 3 times) because the driver action conditions were not satisfied, if the driver action conditions are still not satisfied, at least some of the real-time driving mode information may not be provided to the monitoring terminal. In other words, even though the driver action conditions are not satisfied, if the number of requests from the device for providing the real-time driving mode information is, for example, smaller than a predetermined threshold number, the device for providing the real-time driving mode information may not provide the real-time driving mode information to the monitoring terminal.
Further, as described above, if the verification process for the monitoring terminal is performed, the device for providing the real-time driving mode information may provide the real-time driving mode information to the monitoring terminal by additionally referring to the verification results for the monitoring terminal.
For example, if the monitoring terminal is verified to be the valid monitoring terminal, the device for providing the real-time driving mode information may provide the real-time driving mode information to the monitoring terminal.
As another example, if the monitoring terminal is an invalid monitoring terminal, the device for providing the real-time driving mode information may not provide the real-time driving mode information. In this case, the device for providing the real-time driving mode information may transmit an alarm message about the fact that the provision of the real-time driving mode information has been requested from the invalid monitoring terminal to a user (e.g., the driver).
In addition, with a range of the real-time driving mode information provided to the monitoring terminal set, the device for providing the real-time driving mode information may provide at least some of the real-time driving mode information to the monitoring terminal.
In one example, the range of the information provided may be determined by the user (e.g., the driver) of the host vehicle.
For example, one (specific provision range setting information) of i) first provision range setting information for providing all of the real-time driving mode information to the monitoring terminal or ii) second provision range setting information for providing some of the real-time driving mode information to the monitoring terminal may be input by the user.
Further, in an embodiment in which the specific provision range setting information is acquired, the device for providing the real-time driving mode information may provide at least some of the real-time driving mode information to the monitoring terminal by additionally referring to the specific provision range setting information.
For example, if the terminal of the police that regulates the violation of the traffic regulations is the monitoring terminal, the device for providing the real-time driving mode information may provide information in a minimum range specified in the traffic regulations to the monitoring terminal.
As another example, if the terminal of the police that regulates the violation of the traffic regulations is the monitoring terminal, the device for providing the real-time driving mode information may provide all of the real-time driving mode information to the monitoring terminal.
As another example, if the monitoring terminal is a general terminal located around the host vehicle (e.g., a terminal other than a terminal of the police that regulates the violation of the traffic regulations), the device for providing the real-time driving mode information may provide all of the real-time driving mode information to the monitoring terminal.
In addition, together with at least some of the real-time driving mode information provided to the monitoring terminal, alarm information corresponding to the operation of providing at least some of the real-time driving mode information to the monitoring terminal may be provided to the driver of the host vehicle.
In other words, the alarm information indicating that the real-time driving mode information is provided to the monitoring terminal may be provided to the driver of the host vehicle.
In an embodiment, a history of at least some of the real-time driving mode information provided to the monitoring terminal may be stored in the host vehicle or an external storage space. Additionally, the user may set a range of the stored history.
An example of a data format of the real-time driving mode information, according to an embodiment, is as follows.
For example, the data format of the real-time driving mode information may be a JSON data format as described below.
In an example, the real-time driving mode information may contain a header and data.
The header may include information on a response ID (RES_ID), a response type (ResType_Seq), a vehicle identification (VIN), and a response time (RES_TIME).
Additionally, the data may include information on the autonomous driving level (AUTONOMOUS LEVEL), an autonomous driving function name (FUNTION NAME), and an allowable function (ALLOWANCE-HANDS OFF or the like).
For example, in a case of “ALLOWANCE HANDS OFF”: “15s”, this may mean a limit time that the driver may take hands off the steering wheel under the autonomous driving function corresponding to the current autonomous driving level.
Because one autonomous function has been described above for convenience, the data format of the real-time driving mode information is described as including only “data1”. However, if two or more autonomous functions are operable, a plurality of data may be included.
A device 100 for providing the real-time driving mode information according to one embodiment may include a memory 120 storing computer-executable instructions and at least one processor 110 that accesses to the memory 120 and executes instructions 122.
The processor 110 may acquire the request for the real-time driving mode information of the host vehicle from the monitoring terminal outside the host vehicle.
The processor 110 may check the real-time driving mode information corresponding to the host vehicle.
The processor 110 may determine whether the driver action conditions corresponding to the real-time driving mode information are satisfied by referring to (e.g., based on) the driver state information of the host vehicle.
Additionally, the processor 110 may provide at least some of the real-time driving mode information to the monitoring terminal by referring to (e.g., based on) the determination result.
Accordingly, communication between the autonomous driving vehicles and an external ecosystem may be achieved efficiently, and unnecessary exercise of police power may be minimized.
