Description

Technical Field

[0001] This invention relates to the field of safe driving technology, and in particular to a safety feedback system and method for intelligent driving. Background Technology

[0002] Chinese Patent Publication No. CN102700501A discloses a car seatbelt warning device. This solution includes a seatbelt and a seatbelt buckle. It also includes a seat buckle, a controller, and an instrument panel warning device. A metal contact switch is installed inside the seat buckle; when the metal buckle is detected, a signal is sent to the controller. Signal detection devices are installed on the seatbelt, seat, and seat buckle to detect the length of the seatbelt pull-out, the fore-and-aft position of the seat, and the position of the seatbelt buckle, respectively, and transmit the obtained signals to the controller. The controller processes the signals and sends the result to the instrument panel warning device. Therefore, this solution only provides a warning regarding whether the seatbelt is engaged and does not consider other factors affecting driving safety. Summary of the Invention

[0003] Therefore, the present invention provides a safety feedback system and method for intelligent driving to overcome the problems of low efficiency and low driving safety in the prior art.

[0004] To achieve the above objectives, in one aspect, the present invention provides a safety feedback system for intelligent driving, comprising,

[0005] The status acquisition module is used to collect the seat belt insertion status and airbag operation status in the vehicle in real time.

[0006] The safety analysis module is used to perform an initial analysis of driving safety based on the seat belt insertion status, and a secondary analysis of driving safety based on the airbag operation status.

[0007] The safety analysis module includes a first analysis unit and a second analysis unit. During the initial analysis of driving safety, the first analysis unit selects the seat containing the target user as the target seat and obtains the seatbelt insertion status of the target seat for driving safety analysis. The first analysis unit performs the initial analysis of driving safety based on the proportion of high-risk seats and adjusts the results based on the location of the high-risk seats. During the second analysis of driving safety, the second analysis unit obtains the operating status of each airbag and performs a second analysis of driving safety based on the seatbelt insertion status of the seats adjacent to the airbags.

[0008] The security assessment module is used to assess operational security based on the security analysis results obtained from the initial analysis.

[0009] The alarm feedback module is used to issue alarms in different ways according to different risk states when there is a risk to driving safety. The alarm feedback module issues alarms when there is low risk, medium risk and high risk to driving safety.

[0010] Furthermore, when the first analysis unit performs an initial analysis of driving safety, it obtains the proportion of risky seats A, setting A = A1 / A2, where A1 is the number of risky seats and A2 is the total number of seats. The first analysis unit compares the proportion of risky seats A with a preset proportion of risky seats A0. The safety judgment module judges the operational safety based on the comparison result.

[0011] When 0 < A ≤ A0, the safety judgment module determines that there is a low risk to driving safety;

[0012] When A > A0, the safety judgment module determines that there is a medium risk to driving safety.

[0013] Furthermore, when adjusting the initial analysis results, the first analysis unit obtains the positions of each risk seat and adjusts the initial analysis results accordingly.

[0014] When a front seat is present in the risk seats, if the driving safety is determined to be low, the first analysis unit will adjust the operational safety judgment result to medium risk.

[0015] When there is no front seat among the risk seats, if the driving safety is determined to be at medium risk, the first analysis unit will adjust the operational safety judgment result to low risk.

[0016] Furthermore, the second analysis unit acquires the operational status of each airbag and the seatbelt insertion status of adjacent seats, and performs a secondary analysis on the adjusted initial analysis results, wherein...

[0017] When all airbags are operating normally, the second analysis unit maintains the initial analysis results;

[0018] When the airbag malfunctions, the second analysis unit obtains the number of malfunctioning airbags and corrects the initial analysis results.

[0019] Furthermore, when correcting the initial analysis results, the second analysis unit obtains the number of faulty airbags N, compares it with the preset number of faulty airbags N0, and corrects the initial analysis results based on the comparison results.

[0020] When N > N0, the second analysis unit corrects the initial operational safety judgment result to high risk;

[0021] When N≤N0, if the seat adjacent to the faulty airbag is the target seat and the target seat is not a risky seat, the second analysis unit will correct the initial operational safety judgment result to medium risk. If the seat adjacent to the faulty airbag is the target seat and the target seat is a risky seat, the second analysis unit will correct the initial operational safety judgment result to high risk.

[0022] Furthermore, the alarm feedback module acquires the operational safety assessment results after secondary analysis and issues alarms based on different driving safety risks.

[0023] When the driving safety risk is low, the alarm feedback module will issue an alarm in different ways based on user interaction feedback;

[0024] When the driving safety risk is medium risk, the alarm feedback module will issue an alarm in different ways according to the risk factors.

[0025] When the driving safety risk is high, the alarm feedback module will issue an airbag malfunction alarm, prompting the user to stop driving and have the airbags inspected in a timely manner.

[0026] Furthermore, when the driving safety risk is low, if the user interaction feedback result indicates that the rear seat belt reminder is off, the alarm feedback module controls the seat belt warning light to flash, collects the seat belt unfastened duration T, compares it with various preset durations, and adjusts the state of the seat belt warning light according to the comparison result.

[0027] No adjustment is made when T≤T1;

[0028] When T1 < T ≤ T2, the alarm feedback module will change the state of the seat belt warning light from flashing to constantly on;

[0029] When T2 < T, the alarm feedback module will change the status of the seat belt warning light from always on to off;

[0030] Where T1 is the first preset duration and T2 is the second preset duration, set to 5 < T1 < 10 and T2 ≥ 10, with the unit being seconds.

[0031] Furthermore, when the driving safety risk is low, if the user interaction feedback result is that the rear seat belt reminder is activated, the alarm feedback module will remind the user of the location of the risky seat while controlling the seat belt warning light to issue an alarm.

[0032] Furthermore, when the driving safety risk is medium risk, if the airbag is operating normally, the alarm feedback module will issue a seatbelt unfastened warning to remind the user to fasten their seatbelt in time. If the airbag is malfunctioning, the alarm feedback module will issue an airbag malfunction warning to remind the user that there is a risk to driving safety and the airbag needs to be inspected in time.

[0033] On the other hand, the present invention also provides a safety feedback method for intelligent driving, comprising:

[0034] Step S1: Real-time monitoring of the seatbelt insertion status and airbag operation status inside the vehicle;

[0035] Step S2: Perform an initial analysis of driving safety based on the seat belt insertion status, and a secondary analysis of driving safety based on the airbag operation status.

[0036] Step S3: Determine the operational safety based on the safety analysis results obtained from the initial analysis;

[0037] Step S4: When there is a risk to driving safety, issue warnings in different ways depending on the different risk states.

[0038] Compared with existing technologies, the beneficial effects of this invention are as follows: by collecting real-time data on the seat belt insertion status and airbag operation status, the operating status of in-vehicle safety protection devices can be obtained in real time. A first analysis unit performs an initial analysis of driving safety to determine the impact of seat belt insertion status on driving safety in different seats. This initial analysis improves user driving safety. A second analysis unit performs a secondary analysis of driving safety to determine the impact of airbag operation status in various locations on driving safety. This secondary analysis further improves user driving safety. A safety judgment module assesses operational safety, and an alarm feedback module issues safety warnings when driving safety risks exist. These warnings allow users to be promptly informed of potential safety hazards, thereby further improving user driving safety. Attached Figure Description

[0042] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0043] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0044] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] Please see Figure 1 As shown, this is a structural schematic diagram of the safety feedback system for intelligent driving in this embodiment. The system includes:

[0046] The status acquisition module is used to collect the seat belt insertion status and airbag operation status in the vehicle in real time; the insertion status includes inserted and not inserted, and the operation status includes normal and fault.

[0047] The safety analysis module is used to perform an initial analysis of driving safety based on the seat belt insertion status, and a secondary analysis of driving safety based on the airbag operation status. The analysis module is connected to the status acquisition module.

[0048] The security judgment module is used to judge the operational security based on the security analysis results obtained from the secondary analysis. The security judgment module is connected to the security analysis module.

[0049] The alarm feedback module is used to issue safety alarms when there is a risk to driving safety. The alarm feedback module is connected to the safety judgment module.

[0050] Please see Figure 2As shown, this is a structural schematic diagram of the safety analysis module in this embodiment. The safety analysis module includes a first analysis unit and a second analysis unit. During the initial analysis of driving safety, the first analysis unit takes the seat with the target user as the target seat and obtains the seat belt insertion status of the target seat for driving safety analysis. The first analysis unit takes the target seat with the seat belt not inserted as the risk seat and calculates the risk seat ratio, which is defined as the proportion of the number of risk seats to the number of target seats. The first analysis unit is used to perform the initial analysis of driving safety based on the risk seat ratio and adjust the initial analysis results according to the position of the risk seats. During the second analysis of driving safety, the second analysis unit obtains the operating status of each airbag and combines it with the seat belt insertion status of the seats adjacent to the airbags to perform the second analysis of driving safety.

[0051] Specifically, the system described in this embodiment is applied to an in-vehicle computer. It analyzes and judges driving safety by collecting real-time data on the seat belt insertion status and the airbag operation status. When there is a risk to driving safety, it promptly alerts the user to improve the user's driving safety.

[0052] Specifically, in this embodiment, the real-time acquisition of the seat belt insertion status and airbag operation status inside the vehicle is used to obtain the real-time operation status of the vehicle's safety protection devices. A first analysis unit performs an initial analysis of driving safety to determine the impact of the seat belt insertion status on driving safety at different seats. This initial analysis based on seat belt insertion status improves user driving safety. A second analysis unit performs a second analysis of driving safety to determine the impact of the airbag operation status at various locations inside the vehicle on driving safety. This second analysis based on airbag operation status further improves user driving safety. A safety judgment module assesses operational safety, and an alarm feedback module issues safety alarms when driving safety risks exist. These alarms allow users to be promptly informed of potential safety hazards, thereby further improving user driving safety.

[0053] Specifically, in this embodiment, when the first analysis unit performs an initial analysis of driving safety, it obtains the proportion of risky seats A, setting A = A1 / A2, where A1 is the number of risky seats and A2 is the total number of seats. The first analysis unit compares the proportion of risky seats A with a preset proportion of risky seats A0. The safety judgment module judges the operational safety based on the comparison result.

[0054] When 0 < A ≤ A0, the safety judgment module determines that there is a low risk to driving safety;

[0055] When A > A0, the safety judgment module determines that there is a medium risk to driving safety.

[0056] Specifically, in this embodiment, when the first analysis unit adjusts the initial analysis results, it obtains the positions of each risk seat and adjusts the initial analysis results accordingly.

[0057] When a front seat is present in the risk seats, if the driving safety is determined to be low, the first analysis unit will adjust the operational safety judgment result to medium risk.

[0058] When there is no front seat among the risk seats, if the driving safety is determined to be at medium risk, the first analysis unit will adjust the operational safety judgment result to low risk.

[0059] Specifically, in this embodiment, the first analysis unit performs an initial analysis of driving safety by acquiring the proportion of risky seats. This analysis allows for timely identification of current driving safety risks, thereby improving driving safety. When the proportion of risky seats is within a threshold, the driving is judged to have low risk; otherwise, it is judged to have medium risk. The first analysis unit also adjusts the initial analysis results based on the location of each risky seat. The risk assessment result is increased when front seats are present and decreased when front seats are absent. By adjusting the initial analysis results based on the location of risky seats, the risk assessment result is changed, thereby providing timely and effective risk warnings to the user and further improving driving safety. This embodiment does not specifically limit the proportion of risky seats A; those skilled in the art can set it according to the number of seats in the vehicle, such as setting A to a value of 0.2 or 0.25.

[0060] Specifically, in this embodiment, the second analysis unit acquires the operating status of each airbag and the seat belt insertion status of adjacent seats, and performs a secondary analysis on the adjusted initial analysis results, wherein...

[0061] When all airbags are operating normally, the second analysis unit maintains the initial analysis results;

[0062] When the airbag malfunctions, the second analysis unit obtains the number of malfunctioning airbags and corrects the initial analysis results.

[0063] Specifically, in this embodiment, when the second analysis unit corrects the initial analysis results, it obtains the number of faulty airbags N, compares it with the preset number of faulty airbags N0, and corrects the initial analysis results based on the comparison results.

[0064] When N > N0, the second analysis unit corrects the initial operational safety judgment result to high risk;

[0065] When N≤N0, if the seat adjacent to the faulty airbag is the target seat and the target seat is not a risky seat, the second analysis unit will correct the initial operational safety judgment result to medium risk. If the seat adjacent to the faulty airbag is the target seat and the target seat is a risky seat, the second analysis unit will correct the initial operational safety judgment result to high risk.

[0066] Specifically, in this embodiment, the second analysis unit corrects the initial driving safety judgment result by acquiring the operating status of each airbag. This correction improves the accuracy of driving safety risk judgment, thereby enhancing driving safety. The second analysis unit acquires the number of faulty airbags. When the number exceeds a threshold, the number of faulty airbags is high. The risk level is corrected to high risk to change the alarm method, allowing the user to respond promptly based on the risk alarm, thereby reducing the impact of faulty airbags on driving safety. When the number of faulty airbags is within the threshold but the seat adjacent to the faulty airbag is a risky seat, the second analysis unit corrects the operating safety judgment result to high risk to further improve driving safety.

[0067] Specifically, in this embodiment, the alarm feedback module obtains the operational safety judgment result after secondary analysis and issues alarm reminders based on different driving safety risks.

[0068] When the driving safety risk is low, the alarm feedback module will issue an alarm in different ways based on user interaction feedback;

[0069] When the driving safety risk is medium risk, the alarm feedback module will issue an alarm in different ways according to the risk factors.

[0070] When the driving safety risk is high, the alarm feedback module will issue an airbag malfunction alarm, prompting the user to stop driving and have the airbags inspected in a timely manner.

[0071] Specifically, in this embodiment, the alarm feedback module uses different methods to issue alarms based on different risk levels, so as to remind users of the impact of different risk levels on operational safety, enabling users to take timely and effective measures to further improve user driving safety.

[0072] Specifically, in this embodiment, when the driving safety risk is low, if the user interaction feedback result is that the rear seat belt reminder is off, the alarm feedback module controls the seat belt warning light to flash, collects the seat belt unfastened duration T, compares it with various preset durations, and adjusts the state of the seat belt warning light according to the comparison result.

[0073] No adjustment is made when T≤T1;

[0074] When T1 < T ≤ T2, the alarm feedback module will change the state of the seat belt warning light from flashing to constantly on;

[0075] When T2 < T, the alarm feedback module will change the status of the seat belt warning light from always on to off;

[0076] Where T1 is the first preset duration and T2 is the second preset duration, set to 5 < T1 < 10 and T2 ≥ 10, with the unit being seconds.

[0077] Specifically, in this embodiment, when the driving safety risk is low, if the user interaction feedback result indicates that the rear seatbelt reminder is on, the alarm feedback module, while controlling the seatbelt warning light to issue an alarm, also reminds the user of the location of the at-risk seat. In this embodiment, the control method for the seatbelt warning light when the rear seatbelt reminder is on is the same as when it is off. It is understood that this embodiment does not specifically limit the method of reminding users of the at-risk seat location. Those skilled in the art can provide reminders by setting location icons on the vehicle's central control screen, or by setting other methods, as long as the location reminder requirement is met.

[0078] Specifically, in this embodiment, the alarm feedback module issues an alarm when the driving safety risk is low. It obtains user feedback and then issues the alarm in different ways. If the user feedback indicates the rear seatbelt reminder is off, the alarm is triggered by controlling the seatbelt warning light's state based on the duration of seatbelt unfastened. The warning light's state changes as the unfastened duration reaches different thresholds, eventually turning off completely, thus providing an alarm to the user within the specified timeframe. If the user feedback indicates the rear seatbelt reminder is on, the location is displayed simultaneously with the seatbelt warning light, allowing the user to respond promptly and effectively, further improving driving safety. It is understood that this embodiment does not specifically limit the user interaction process. For example, a button could be installed inside the vehicle to receive user feedback regarding the rear seatbelt reminder. Those skilled in the art can also set other interaction methods, such as voice interaction, as long as the interaction feedback requirements are met.

[0079] Specifically, in this embodiment, when the driving safety risk is medium risk, if the airbag is operating normally, the alarm feedback module will issue a seatbelt unfastened warning, reminding the user to fasten their seatbelt immediately. If the airbag malfunctions, the alarm feedback module will issue an airbag malfunction warning, reminding the user that there is a risk to driving safety and the airbag needs to be inspected promptly. It is understood that this embodiment does not limit the alarm method. Those skilled in the art can set up voice alarms or other alarm methods when issuing seatbelt unfastened and airbag malfunction warnings; this embodiment does not impose specific limitations.

[0080] Please see Figure 3 As shown, this is a flowchart illustrating the safety feedback method for intelligent driving in this embodiment. The method includes:

[0081] Step S1: Real-time monitoring of the seatbelt insertion status and airbag operation status inside the vehicle;

[0082] Step S2: Perform an initial analysis of driving safety based on the seat belt insertion status, and a secondary analysis of driving safety based on the airbag operation status.

[0083] Step S3: Determine the operational safety based on the safety analysis results obtained from the initial analysis;

[0084] Step S4: When there is a risk to driving safety, issue warnings in different ways depending on the different risk states.

[0085] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
