Description

Technical Field

[0001] The present application relates to the field of automobile early warning technology, and in particular to a vehicle safety warning method and a vehicle safety warning device. Background Art

[0002] Motor vehicles are now an indispensable means of transportation in people's daily lives, but modern people often neglect the maintenance of their vehicles due to their busy schedules, resulting in users being unable to start their vehicles due to abnormal malfunctions while driving.

[0003] However, the status of the vehicle itself determines the user's driving safety. At present, the early warning schemes in related technologies can be roughly divided into two types. One is that the vehicle's own controller monitors the vehicle status and reminds the user through the instrument when an abnormality is found. The other is to analyze the data through the cloud and warn the user after an abnormality is found. However, the two schemes do not have a public order of importance for the warning information obtained from the analysis, and lack further decomposition of the warning information, which makes it impossible for the driver to correctly judge the current hidden dangers of the vehicle and make timely and accurate responses. Summary of the invention

[0004] Regarding the related technologies, the vehicle safety warning scheme does not further decompose the warning information, resulting in the driver being unable to correctly judge the current hidden dangers of the vehicle and make timely and accurate responses.

[0005] In a first aspect, an embodiment of the present application provides a vehicle safety warning method, the vehicle safety warning method comprising:

[0006] Classify safety hazards into multiple safety warning levels according to their importance to vehicle driving, and set a corresponding warning mechanism for each safety warning level;

[0007] Determine the safety warning level of the vehicle's current safety hazard based on the collected vehicle basic information, vehicle status information and current driving information;

[0008] A safety warning is issued using a warning mechanism corresponding to the safety warning level of the current safety hazard.

[0009] In combination with the first aspect, in one implementation, the safety warning information is classified into multiple safety warning levels according to the importance to vehicle driving, including:

[0010] The safety warning information is classified into severe safety warning, moderate safety warning and mild safety warning; among them,

[0011] The vehicle safety hazard corresponding to the severe safety warning is a safety hazard that will seriously affect driving safety and cause the vehicle to be unable to start or require immediate parking;

[0012] The vehicle safety hazard corresponding to the moderate safety warning is that the vehicle can still be driven but needs to be immediately confirmed and repaired at a service station;

[0013] The vehicle safety hazards corresponding to the mild safety warnings are safety hazards that do not affect driving and do not require immediate repair.

[0014] In combination with the first aspect, in one implementation, setting a corresponding warning mechanism for each safety warning level includes:

[0015] Set visual warnings, audible warnings and tactile warnings simultaneously for severe safety warnings;

[0016] Set both visual and audible warnings for moderate safety warnings

[0017] Set visual warnings for minor safety alerts.

[0018] In combination with the first aspect, in one implementation, the tactile warning includes: a steering wheel and a seat issuing a vibration warning.

[0019] In combination with the first aspect, in one implementation, the using of a warning mechanism corresponding to a safety warning level of a current safety hazard for performing a safety warning includes:

[0020] If the vehicle's current safety hazard is in a severe safety warning, determine whether the vehicle's driving speed or vehicle fault meets the preset stress requirements;

[0021] If the vehicle meets the preset stress requirements, visual warnings, auditory warnings and tactile warnings are executed. If the vehicle does not meet the preset requirements, only tactile warnings and auditory warnings are executed.

[0022] In combination with the first aspect, in one implementation, the preset stress requirement includes that the current vehicle speed is higher than 80 km / h or a vehicle failure causes the vehicle to be unable to decelerate or the brakes fail.

[0023] In combination with the first aspect, in one implementation, the collecting of basic vehicle information, vehicle status information and current driving information includes:

[0024] Collect vehicle model information, age of current vehicle, total vehicle mileage, and vehicle maintenance information;

[0025] Collect vehicle status information and current fuel level;

[0026] Collect the vehicle's location information, the vehicle's driving time for this trip, and the vehicle's current speed and rotation speed.

[0027] In combination with the first aspect, in one implementation, the determining the safety warning level of the current safety hazard of the vehicle based on the combination of the three factors further includes:

[0028] Determine whether the vehicle has bad driving behavior based on the driving time of the vehicle's current trip and the vehicle's current speed and rotation speed;

[0029] If there is bad driving behavior, the safety warning level will be adjusted according to the bad driving behavior.

[0030] In combination with the first aspect, in one implementation, after the warning mechanism corresponding to the safety warning level of the current safety hazard is used to issue a safety warning, the method further includes:

[0035] The warning unit is used to issue a safety warning using the warning mechanism corresponding to the safety warning level of the current safety hazard.

[0036] The beneficial effects brought by the technical solution provided in the embodiments of the present application include:

[0037] This application classifies safety hazards according to their importance, and determines the importance level of the vehicle's current safety hazards by combining basic vehicle information, vehicle status information, and current driving information, and then provides appropriate solutions, so that drivers and passengers can discover safety hazards in a timely manner and quickly resolve them, reducing the loss of personal and property safety and improving driving safety. Furthermore, this application adds the vehicle's own information as a judgment indicator for the current hazard classification, making the information more comprehensive and improving the accuracy of judgment.

[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] Regarding the related technologies, the vehicle safety warning scheme does not further decompose the warning information, resulting in the driver being unable to correctly judge the current hidden dangers of the vehicle and make timely and accurate responses.

[0045] First, as Figure 1 and Figure 3 As shown, an embodiment of the present application provides a vehicle safety warning method, the vehicle safety warning method comprising:

[0046] Step S1: classify potential safety hazards into multiple safety warning levels according to their importance to vehicle driving, and set a corresponding warning mechanism for each safety warning level.

[0047] In some specific embodiments, the above step S1 includes:

[0048] Step S1a: classify the safety warning information into severe safety warning, moderate safety warning, and mild safety warning; wherein,

[0049] The vehicle safety hazards corresponding to the severe safety warning are safety hazards that will seriously affect driving safety and cause the vehicle to be unable to start or require immediate parking; the vehicle safety hazards corresponding to the moderate safety warning are safety hazards that the vehicle can still be driven but needs to go to the service station immediately for confirmation and repair; the vehicle safety hazards corresponding to the minor safety warning are safety hazards that do not affect driving and do not require immediate repair.

[0050] In some preferred implementations, the mild safety warning can be subdivided into a primary mild safety warning and a secondary mild safety warning according to their importance.

[0051] In some optional implementations, the safety warning level classification rules are shown in the following table:

[0052]

[0053] Step S1b: setting a corresponding warning mechanism for each safety warning level.

[0054] In some specific embodiments, the above step S1b includes: setting a visual warning, an auditory warning and a tactile warning for a severe safety warning; setting a visual warning and an auditory warning for a moderate safety warning; and setting a visual warning for a mild safety warning.

[0055] In combination with the above preferred implementation, among the visual warnings, auditory warnings and tactile warnings set for severe safety warnings, the visual warnings include: the instrument interface displays a stop light, the instrument interface displays a corresponding fault light, the instrument interface pops up a warning window, and the entertainment function of the vehicle entertainment screen is suspended, and the window reminds the user to stop the car. The auditory warning includes: the entertainment screen voice broadcast reminds the user that the vehicle has a fault and needs to stop. The tactile warning includes: the steering wheel vibrates to remind the user to pay attention, and the seat vibrates to remind the user to pay attention.

[0056] Furthermore, for the medium safety warning, visual warning and auditory warning are set at the same time. The visual warning includes: the instrument interface displays a warning alarm light, the instrument interface displays a corresponding fault light, and the instrument interface pops up a warning window. The auditory warning includes: the entertainment screen voice broadcast reminds the user that the vehicle has a fault and needs to be repaired.

[0057] In some optional implementations, the visual warning set for the first-level mild safety warning includes: the instrument interface displays a warning alarm light, the instrument interface displays a corresponding fault light, and the instrument displays fault information in text. The visual warning set for the second-level mild safety warning only includes: the instrument interface displays prompt information in text.

[0058] It should be noted that the difference between pop-up window reminders and text reminders is that pop-up window reminders are displayed in the middle of the instrument, and users can confirm more quickly. Text reminders are located at the bottom of the instrument and users can view them but it does not affect the viewing of other driving information. The priority is lower than pop-up window reminders.

[0059] It is understandable that the advantage of the overall solution is that, through the hierarchical management of vehicle safety warning information and the optimization of interactive forms, the user's recognition of vehicle safety warning information is reduced, which effectively improves driving safety while reducing the user's handling costs for vehicle failures and further increases the vehicle's service life.

[0060] Step S2: Determine the safety warning level of the current safety hazard of the vehicle based on the collected vehicle basic information, vehicle status information and current driving information.

[0061] In some specific implementation manners, the above step S2 includes:

[0062] Step S2a, collecting basic vehicle information, vehicle status information and current driving information.

[0063] Specifically, the vehicle information needs to be collected first. In addition to receiving information from controllers such as the body control module (BCM) and the body electronic control system, the following contents need to be transmitted to the cloud, including but not limited to: vehicle model, age, total mileage, vehicle maintenance record, operating status of each vehicle system, vehicle speed, rotation speed, fuel level, vehicle location, driving time of the vehicle this trip, fault code, and user personal information. Among them, fault information and information that the cloud analysis believes needs to be used as a safety warning for the user need to be recorded locally and automatically overwritten after a certain storage period. The overwriting period depends on the memory of the storage device.

[0064] Furthermore, basic vehicle information includes: vehicle model, age, total mileage and vehicle maintenance information; among which, the vehicle model is used for comparison with other similar models during cloud analysis. Age is used by the cloud to analyze the problems that are prone to occur in vehicles at various stages in combination with past data, and dynamically adjust the warning information. The total mileage of the vehicle is used by the cloud to analyze the problems that are prone to occur in vehicles when the total mileage reaches a certain value in combination with past data, and dynamically adjust the warning information. Vehicle maintenance information is used to confirm the maintenance status of the vehicle.

[0065] The vehicle status information includes: the operation information of each vehicle system and the fuel level. The operation information of each vehicle system is used to receive vehicle fault information. The fuel level is used to evaluate the remaining mileage of the vehicle.

[0066] Driving information includes: vehicle location, driving time, speed, and rotation speed of the vehicle. The vehicle location is used to analyze the road conditions of the current section in combination with high-precision maps and past driving history to provide early warning information to users. The driving time of the vehicle's current trip is used to determine whether the user has fatigued driving behavior. The speed and rotation speed are used to determine whether the user has bad driving behaviors such as speeding and coasting in neutral.

[0067] Step S2b: Determine the safety warning level of the current safety hazard of the vehicle.

[0068] Specifically, the vehicle status information can directly determine whether the vehicle is in good condition without cloud processing. Driving information can be processed through the cloud to confirm whether there are risks that affect vehicle safety, and to promptly remind users to issue warnings. Basic vehicle information can affect the cloud's analysis and judgment of driving information. For example, different models perform differently in different road conditions, and the difference in model feelings can provide users with more accurate warning information; when a vehicle is driven for a certain time or mileage, the wear and tear of its components often grows exponentially, and differentiated warning services can be provided for vehicles of different years of use and driving mileage; if the vehicle is not maintained for a long time, the probability of component damage is higher, and safety risks may be more likely to occur on some road conditions.

[0069] In some preferred implementations, the above step S2b further includes: judging whether the vehicle has bad driving behavior according to the driving time of the vehicle's current trip and the current speed and rotation speed of the vehicle;

[0070] If there is bad driving behavior, the safety warning level will be adjusted according to the bad driving behavior.

[0071] Furthermore, bad driving behaviors include: coasting in neutral gear, fatigue driving, distracted driving and sudden braking.

[0072] It is understandable that when the driver is driving, it is easy to use the vehicle's inertia to slide forward to save fuel, which can be judged as neutral sliding. When the driver drives for a long time without rest, it can be judged as fatigue driving. When the driver chats or makes phone calls while driving, it can be judged as distracted driving. When the driver quickly presses the brake to the bottom to control the speed, it can be judged as emergency braking. The cloud records and analyzes bad driving behaviors, warns them, and adjusts the safety warning level to further improve driving safety.

[0073] It is worth mentioning that the cloud needs to adjust the warning level of some information in response to special circumstances, and the warning level of some information can be increased or decreased based on its frequency of occurrence and changes in the surrounding environment.

[0074] In some optional implementations, the bad driving behavior adjustment logic is summarized as shown in the following table:

[0075]

[0076]

[0077] Step S3: Use the warning mechanism corresponding to the safety warning level of the current safety hazard to issue a safety warning.

[0078] In some specific implementation manners, the above step S3 includes:

[0079] Step S3a: If the current safety hazard of the vehicle is in a severe safety warning, determine whether the vehicle speed or vehicle fault meets the preset stress requirements; if the vehicle does not meet the preset stress requirements, perform visual warnings, auditory warnings and tactile warnings; if the vehicle meets the preset requirements, only perform tactile warnings and auditory warnings. Further, if it is detected that the vehicle is still in a driving state (vehicle speed is less than 80km / h and greater than 2km / h) 5 seconds after the fault reminder, the steering wheel and seat start vibrating reminders.

[0080] Alternatively, if Figure 2 As shown, the above-mentioned preset stress requirements include that the current vehicle speed is higher than 80 km / h or a vehicle failure causes the vehicle to be unable to decelerate or the brakes fail.

[0081] It is understandable that if the driver is stimulated without warning while driving at high speed, it is easy to affect driving safety, so tactile feedback needs to take into account the impact of human stress response on driving.

[0082] Step S3b: Pushing driving behavior suggestions or troubleshooting methods in the vehicle according to the safety warning level of the current safety hazard.

[0083] It is understandable that after receiving the warning mechanism, drivers and passengers often do not know how to deal with the safety hazards. Therefore, after the warning is executed, solutions need to be provided to drivers and passengers to help them find and solve the safety hazards of the vehicle as soon as possible.

[0084] Specifically, the above step S3b includes:

[0085] When the warning mechanism after a severe safety warning is executed, after the vehicle stops, the cloud pushes fault information and quick response measures to the user's mobile phone to remind the user to take action.

[0086] When the warning mechanism after the moderate safety warning is executed, after the vehicle stops, the cloud pushes fault information to the user's entertainment screen and recommends the nearest service station based on the vehicle's location. At the same time, it pushes maintenance service notifications to the mobile phone, so that users can quickly get in touch with the service station.

[0087] When the warning mechanism after the first-level mild safety warning is executed, after the vehicle stops, the cloud will push detailed fault information and handling methods to the user's entertainment screen, and push the fault information to the mobile phone. The user can also view or seek further help on the mobile phone.

[0088] When the warning mechanism after the second-level mild safety warning is executed, the cloud pushes driving behavior suggestions or fault information and handling methods to the user after the vehicle stops. For fault information, when the user arrives at the service station, the cloud will remind the service station staff to read and process the information through the vehicle's on-board diagnostic system (OBD).

[0089] Furthermore, the present application provides a specific embodiment of the security warning method of the present application for specific application scenarios:

[0090] Scenario 1: The controller receives a fault code that causes the vehicle to be unable to drive normally. This is a Level 1 safety warning. The vehicle is currently stationary. The STOP light and the corresponding fault light on the instrument panel light up, and a pop-up window reminds the user of the fault details (such as Figure 4 The entertainment screen will announce the fault information and remind the user not to start the vehicle further. The user can quickly call the service station for help in the interface. If the vehicle is detected to change from a stationary state to a driving state (vehicle speed greater than 2km / h), the steering wheel and seat will start vibrating to remind the user.

[0091] The cloud records the fault information and immediately transmits it to the user's mobile phone. The user can learn the fault details on the mobile phone and contact the service station with one click. The message content is similar to: "Your vehicle has been detected to have a fault. You can contact the service station by calling."

[0092] Scenario 2: The controller receives a fault code that causes the vehicle to be unable to drive normally, which is a level 1 safety warning. The vehicle is currently in motion. At this time, the STOP light and the corresponding fault light on the instrument panel light up, and a pop-up window reminds the user of the fault details. The entertainment screen broadcasts the fault information and reminds the user to stop the car as soon as possible. The user can quickly call the service station for help within the interface.

[0093] Haptic feedback needs to take into account the impact of human stress response on driving. If the driver is stimulated without warning while driving at high speed, it is easy to affect driving safety. It is recommended to block the haptic feedback function in special situations, for example:

[0094] If the vehicle speed is higher than 80km / h, in order to avoid causing accidents due to excessive tension of the user, the steering wheel and seat vibration will not be activated.

[0095] If a vehicle failure causes the vehicle to be unable to slow down or the brakes fail, in order to avoid affecting user operation, the steering wheel and seat vibration will not be activated.

[0096] If it is detected that the vehicle is still in motion (vehicle speed is less than 80km / h and greater than 2km / h) 5 seconds after the fault reminder, the steering wheel and seat will start vibrating as a reminder.

[0097] The cloud records the fault information and immediately transmits it to the user's mobile phone. The user can learn the fault details on the mobile phone and contact the service station with one click. The message content is similar to: "Your vehicle has been detected to have a fault. You can contact the service station by calling."

[0098] Scenario 3: The controller receives a fault code. This fault requires the user to go to a service station for repair. It is a secondary safety warning. At this time, the warning light and the corresponding fault light on the instrument panel light up, and a pop-up window reminds the user of the fault details. The entertainment screen voice broadcast reminds the user that the vehicle has a fault and needs repair. The user can click one button to navigate to the service station or click to call the service station.

[0099] The cloud records the fault information and immediately transmits it to the user’s mobile phone. The user can learn the fault details on the mobile phone and contact the service station with one click.

[0100] Scenario 4: The controller receives a fault code. This fault has little impact on driving and can be handled during daily vehicle maintenance. It belongs to the third-level safety warning range. At this time, the warning light and the corresponding fault light on the instrument are on, and the text reminds the user of the detailed fault information. The memory stores this message, and the detailed fault information is displayed on the entertainment screen after parking. The user can click to view the quick solution.

[0101] The cloud will push fault information to users after parking, and users can also view detailed information and solutions on their mobile phones.

[0102] Scenario 5: The controller receives a fault code. This fault has no impact on driving. The user can understand it, but does not need to deal with it immediately. It belongs to the fourth-level safety warning range. At this time, a text reminder message is displayed on the instrument. The memory stores this information, and the detailed information of the fault is displayed on the entertainment screen after parking. The user can click to view the quick solution.

[0103] Scenario 6: When the cloud pushes a message and detects that the weather near the vehicle is about to change or the road section is prone to accidents, which will affect driving safety and fall within the third-level safety warning range, the instrument panel will remind the user of the warning information in text, and the warning information does not need to light up the alarm light. The entertainment screen will broadcast the warning reminder content by voice, and the user can click one button to understand what to do.

[0104] Scenario 7: When the cloud finds that the user is coasting in neutral based on the current driving situation, which affects driving safety and falls within the level 4 safety warning range, the instrument text reminds the user to drive properly. After the vehicle stops, the cloud will push the dangers of the driving behavior to the entertainment screen to remind the user to drive properly. The user can click to view a detailed driving analysis report.

[0105] Scenario 8: When the cloud finds that the user has coasted in neutral for more than five times or that the vehicle is in a position where coasting in neutral is likely to cause an accident, and no adjustment is made after the reminder, a third-level safety warning will be issued. In addition to the text reminder on the instrument panel, the entertainment screen will also use voice broadcast to remind the user to pay attention to driving behavior standards.

[0106] It should be noted that the warning information and driving behavior analysis information in the cloud are somewhat subjective, and users can turn them off according to their own needs.
