Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Attached Figure Description

[0044] Figure 1 This is a flowchart of the steps of a driving guidance method according to an embodiment of the present invention;

[0045] Figure 2 This is a schematic diagram of a driving guidance device according to an embodiment of the present invention. Detailed Implementation

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] In related technologies, driving guidance systems are often designed for novice drivers, thus their functions are typically comprehensive and numerous. However, as drivers continue to improve their driving skills, they still require driving guidance, albeit only a portion of it. Therefore, existing driving guidance systems do not consider the improvement of driver skills, resulting in a relatively simplistic approach that fails to meet the needs of users with varying driving experience levels.

[0048] Based on this, the inventor proposed the inventive concept of this application: to set different vehicle guidance strategies for drivers of different genders and driving experience, so as to function to guide or assist drivers in avoiding common mistakes.

[0049] This invention provides a driving guidance method, see [link to relevant documentation]. Figure 1 , Figure 1 This application illustrates a flowchart of a driving guidance method according to an embodiment of the present application, applied to a vehicle's infotainment system. The method includes:

[0050] S101: Obtain the user's facial feature information and the user's identity information.

[0051] In this embodiment, for the same vehicle, there may be multiple drivers, each with the same driving skill level. Therefore, when a driver enters the vehicle and has a need to drive, the first step is to identify who the driver is. After the system is activated, the user's biometric features are identified through a DMS (Driver Monitor System) camera located in the driver's seat inside the vehicle cabin. This primarily involves capturing the driver's facial image and making a judgment based on the driver's facial image.

[0052] As an example, a target user profile can be determined from multiple user profiles based on the user's facial feature information. The user's identity is then determined by matching the captured facial image with the facial images stored in the user profile database. The target user profile for the driver can then be selected from the pre-stored user profiles. If no corresponding user profile is found, it indicates a potential risk of the vehicle being used by an unknown person, and the vehicle owner can be notified through the vehicle's communication system.

[0053] User profiles are used to store a user's total safe driving mileage, as well as the safe driving zones and safe driving coefficients set for the user.

[0054] The specific steps for generating a user's profile picture for each user may include:

[0055] S101-1: Based on the driving evaluation parameters of different users, determine the safe driving mileage range and the safe driving coefficient corresponding to the safe driving mileage range for different users;

[0056] S101-2: Based on the user's facial image, driving evaluation parameters, safe driving mileage range, and the safe driving coefficient corresponding to the safe driving mileage range, establish user profiles for different users.

[0057] In the implementations of S102-1 to S102-2, the driving evaluation parameters include at least the user's gender, age, and driving experience. The evaluation methods and scales for different users are different. The evaluation can be based on the user's age or combined with characteristics such as gender.

[0058] As an example, using gender and age as evaluation parameters, consider three users: A, B, and C. Users A and B are both female, but their ages differ; A is 40 years old, and B is 20. Users A and C are male, but A and C are both 40 years old. For female and male users, since female users tend to rely more on in-car driving instructions, a higher safe driving mileage range and a lower safe driving coefficient can be set for them. Conversely, for users of different ages, younger users generally rely less on in-car driving instructions; therefore, a higher safe driving mileage range and a lower safe driving coefficient can be set for older users.

[0059] For example, for user A, the safe driving mileage range is: 0-1500km, with a corresponding safe driving coefficient of 0.5; 1500-3000km, with a corresponding safe driving coefficient of 0.7. For user B, the safe driving mileage range is: 0-1200km, with a corresponding safe driving coefficient of 0.6; 1200-2500km, with a corresponding safe driving coefficient of 0.75. For user C, the safe driving mileage range is: 0-1000km, with a corresponding safe driving coefficient of 0.65; 1000-2000km, with a corresponding safe driving coefficient of 0.78.

[0060] The implementation method for the driving experience parameter is the same as the above implementation method, so it will not be described again.

[0061] After pre-setting the safe driving mileage range and corresponding safe driving coefficient for each user, the user profile is generated by combining each user's facial image and evaluation parameters. The user profile is also used to store the user's total safe driving mileage.

[0062] S102: Obtain the user's total safe driving mileage based on the user's identity information.

[0063] In this embodiment, after reading the user's identity information, the total safe driving mileage recorded in the user's identity information is read to determine the subsequent driving guidance strategy. In this embodiment, this is done by reading the target user profile.

[0064] S103: Determine the user's safe driving level based on the total safe driving mileage, and execute driving guidance policies corresponding to the safe driving level.

[0065] In this embodiment, if the current user is A, after reading user A's total safe driving mileage, the current safe driving level of user A is determined. The specific steps are as follows:

[0066] S103-1: Determine the user's safe driving level based on the correspondence between the total safe driving mileage and the preset safe driving mileage range.

[0067] In this embodiment, as an example, when user A's total safe driving mileage is between 0 and 1500 km, the corresponding safe driving level is Level 1; when user A's total safe driving mileage is between 1500 and 3000 km, the corresponding safe driving level is Level 2; when user A's total safe driving mileage is between 3000 and 4000 km, the corresponding safe driving level is Level 3; and when user A's total safe driving mileage is greater than 4000 km, the corresponding safe driving level is Level 4. Therefore, based on the correspondence between the user's total safe driving mileage and the preset safe driving mileage range, user A's safe driving level can be determined.

[0068] In one feasible implementation, once the current user's safe driving level is determined, a corresponding driving guidance strategy can be executed based on the user's safe driving level. The specific steps can be as follows:

[0069] When the user's safe driving level is Level 1, the driving guidance strategy implemented is: voice broadcast of driver assistance functions, traffic light compliance guidance, and Level 1 road condition compliance guidance;

[0070] When the user's safe driving level is Level 2, the driving guidance strategy implemented is: Level 1 Road Condition Guided Driving; when the user's safe driving level is Level 3, the driving guidance strategy implemented is: Level 2 Road Condition Guided Driving; when the user's safe driving level is Level 4, the driving guidance strategy implemented is: Basic Driving Guidance.

[0071] In this implementation, when the user's safe driving level is Level 1, it indicates that the user is in the initial stage of driving and therefore requires multi-dimensional assistance, such as voice prompts for driver assistance functions, traffic light guidance, and Level 1 road condition guidance. Voice prompts for driver assistance functions may include the following: Lane departure: recognizing solid road lines and reminding the vehicle's location and next steps; reminding the user of the specific distances to objects around the vehicle at low speeds. Additional voice prompts can be added based on specific functions. Traffic light guidance may include the following: advance recognition and reminders of traffic light times, such as whether the current vehicle speed allows passage at a given traffic light; traffic light recognition: in addition to navigation prompts regarding road driving regulations, recognizing and reminding the user of the next steps that can be taken at the current traffic light. Level 1 road condition guidance may include the following: speeding voice reminders; rear vehicle approach reminders; start / stop reminders for light acceleration and braking; pedestrian yielding and pedestrian awareness reminders.

[0072] The aforementioned driver assistance functions, including voice broadcasts, traffic light guidance, and Level 1 road condition guidance, can all have their content customized according to the user's needs and preferences. Therefore, this application does not limit the specific guidance content.

[0073] When a user's safe driving level reaches Level 2, it indicates that their driving skills have improved and they possess a certain level of proficiency. Therefore, some basic guidance functions, such as voice prompts for driver assistance features and traffic light instructions, are no longer needed; Level 1 road condition guidance is sufficient.

[0074] When a user's safe driving level reaches Level 3, it indicates that their driving skills have reached a relatively high level. Therefore, Level 1 road condition guidance is no longer needed and is replaced by Level 2 road condition guidance. Level 2 road condition guidance can include the following: reminders for proper driving; reminders for starting, stopping, and gently pressing the accelerator and brake.

[0075] When a user's safe driving level is Level 4, it means that the user's driving skills have reached a very mature level. Therefore, only basic driving instructions are needed. Basic driving instructions can include the following: various additional functions included in the vehicle's function list.

[0076] After the user controls the vehicle according to the driving guidance strategy, it is also necessary to evaluate the user's safe driving mileage during this driving process. The specific steps can be as follows:

[0077] Determine the target safe driving mileage range within which the total safe driving mileage falls;

[0078] Update the total safe driving mileage based on the target safe driving coefficient corresponding to the target safe driving mileage range.

[0079] In this embodiment, as an example, if user A's current safe driving mileage is 600km, then the target safe driving mileage range for the total safe driving mileage is determined to be 0-1500km, and the safe driving coefficient corresponding to 0-1500km is determined to be 0.5. The step of updating the total safe driving mileage according to the target safe driving coefficient corresponding to the target safe driving mileage range includes:

[0080] Obtain the user's actual driving mileage and scenario evaluation parameters for the current driving cycle;

[0081] Based on the scenario evaluation parameters and the target safe driving coefficient, the actual driving mileage of the current driving cycle is converted into mileage to obtain the safe driving mileage of the current driving cycle.

[0082] The total safe driving mileage is updated based on the safe driving mileage of the current driving cycle.

[0083] In this implementation, the actual driving mileage of the current driving cycle refers to the actual mileage traveled by the user during this driving period according to the driving guidance strategy. Scene evaluation parameters may include: the number of avoidance maneuvers in the current driving cycle, the narrow-path passage speed in the current driving cycle, and the percentage of high-speed driving time in the current driving cycle. The number of avoidance maneuvers refers to the number of times the vehicle performs emergency avoidance maneuvers; the narrow-path passage speed refers to the vehicle's speed when driving on a narrow path; and the percentage of high-speed driving time refers to the percentage of total time spent driving at speeds exceeding a certain threshold. The system records the number of avoidance maneuvers, the narrow-path passage speed, and the percentage of high-speed driving time during the user's driving process within the current driving cycle.

[0084] As an example, the threshold for the number of times a vehicle avoids obstacles can be set to 5, the threshold for the speed of passing through narrow passages can be set to 2 m / s, and the threshold for the percentage of high-speed driving time can be 70%.

[0085] After obtaining the scenario evaluation parameters and safe driving coefficient, the steps for converting the actual driving mileage of the current driving cycle based on the scenario evaluation parameters and the target safe driving coefficient include:

[0086] Calculate the first scenario mileage based on the number of avoidance maneuvers in the current driving cycle;

[0087] Calculate the mileage for the second scenario based on the speed at which the vehicle passes through the narrow passage during the current driving cycle;

[0088] The mileage for the third scenario is calculated based on the percentage of high-speed driving time in the current driving cycle.

[0089] The actual driving mileage for the current driving cycle is converted based on the mileage in the first scenario, the mileage in the second scenario, the mileage in the third scenario, and the target safe driving coefficient.

[0090] In this embodiment, as an example, if the system records 7 avoidance attempts, a narrow passage speed of 3 m / s, and a high-speed driving time percentage of 60%, then firstly, the first scenario mileage is calculated based on the 7 avoidance attempts. The calculation logic for the first scenario mileage is that for each avoidance attempt exceeding a preset threshold, the actual driving mileage is reduced by 10%. Since the actual driving mileage for the current driving cycle is 100 km, the actual converted first scenario mileage is 20 km. Then, the second scenario mileage is calculated based on the narrow passage speed of 3 m / s. The calculation logic for the second scenario mileage is that if the narrow passage speed is greater than a preset threshold, the actual driving mileage is reduced by 5%, so the actual converted second scenario mileage is 5 km. Finally, the third scenario mileage is calculated based on the high-speed driving time percentage. The calculation logic for the third scenario mileage is that for every 10% lower than the threshold for the high-speed driving time percentage, the actual driving mileage is reduced by 10%, so the actual converted third scenario mileage is 10 km.

[0091] The conversion ratios for the first scenario mileage, the second scenario mileage, and the third scenario mileage differ for different users and their different safe driving levels.

[0092] After determining the mileage for the first, second, and third scenarios, the actual safe driving mileage is used to reduce the mileage for the first, second, and third scenarios. Then, the mileage is multiplied by the corresponding safe driving coefficient of 0.5. This determines that the safe driving mileage for the current driving cycle is 32.5 km. The safe driving mileage for the current driving cycle is then added to the total safe driving mileage to update the total safe driving mileage.
