Description

Technical Field

[0001] The present invention relates to the technical field of vehicle safety, and particularly relates to a vehicle abnormal reminder method, a controller, a vehicle abnormal reminder device, and a vehicle. Background Art

[0002] In the field of vehicle safety, the alarm system is a key link to ensure the safety of drivers and passengers. In related technologies, the alarm system completes the alarm reminder action by configuring an alarm speaker in the vehicle. However, the alarm reminder method of this alarm reminder system is single, and only relies on a single alarm speaker to sound. Once this alarm speaker fails, the entire alarm function will completely fail, and it cannot provide timely warning information for the driver, which may lead to serious safety accidents. Summary of the Invention

[0003] One of the purposes of the present invention is to provide an abnormal reminder method to solve the technical problem that the alarm function fails due to the failure of a single alarm speaker in related technologies, and can use the vibration sound waves of at least one motor in the vehicle to provide multi-level and highly reliable alarm reminders for the driver in the case of the failure of the alarm device, effectively improving the overall safety of the vehicle; the second purpose is to provide a controller; the third purpose is to provide a vehicle abnormal reminder device; the fourth purpose is to provide a vehicle.

[0004] To achieve the above purposes, the technical solutions adopted by the present invention are as follows:

[0005] A vehicle abnormal reminder method includes: obtaining the status information of the vehicle, and collecting the environmental information of the current environment where the vehicle is located; identifying the actual scene where the vehicle is located according to the status information and the environmental information, and determining whether the actual scene meets the preset abnormal reminder condition; if the preset abnormal reminder condition is met, matching at least one target motor of the vehicle and its vibration sound generation method according to the actual scene, and controlling at least one target motor to perform abnormal reminder according to the corresponding vibration sound generation method.

[0006] According to the vehicle abnormal reminder method of the embodiments of the present application, first, the status information of the vehicle is obtained, and the environmental information of the current environment where the vehicle is located is collected. According to the status information and the environmental information, the actual scene where the vehicle is located is identified, and it is determined whether the actual scene meets the preset abnormal reminder condition. If the preset abnormal reminder condition is met, at least one target motor of the vehicle and its vibration sound generation method are matched according to the actual scene, and at least one target motor is controlled to perform abnormal reminder according to the corresponding vibration sound generation method. Thus, this method can, in the case of the failure of the alarm device, use the vibration sound waves of at least one motor in the vehicle to provide multi-level and highly reliable alarm prompts for the driver, solve the technical problem in the related art that the alarm function fails due to the failure of a single alarm speaker, and effectively improve the overall safety of the vehicle.

[0007] According to an embodiment of the present application, matching at least one target motor of the vehicle and its vibration sound generation method according to the actual scene includes: determining an alarm signal according to the actual scene; determining the level of the alarm signal according to the preset alarm priority corresponding to the actual scene; and matching at least one target motor of the vehicle and its vibration sound generation method based on the level of the alarm signal.

[0008] According to the above technical means, different target motors and their vibration sound generation methods are matched according to the level of the alarm signal, so as to realize the reasonable allocation of vehicle resources. For example, when the level of the alarm signal is relatively high, the window motor and the seat motor are simultaneously driven to vibrate and generate sound. Through the collaborative action of multiple motors, a stronger and more easily recognizable alarm effect is generated; when the level of the alarm signal is relatively low, a smaller number of motors can be selected to generate sound, which not only ensures the effectiveness of the alarm prompt but also reasonably utilizes vehicle resources, avoiding unnecessary energy consumption and equipment wear.

[0009] According to an embodiment of the present application, when the actual scene meets multiple preset abnormal reminder conditions, it further includes: determining multiple target abnormal scenes corresponding to the actual scene, where the target abnormal scene corresponds to the preset abnormal reminder condition; determining the alarm trigger order based on the preset alarm priorities respectively corresponding to the multiple target abnormal scenes; and according to the alarm trigger order, matching at least one target motor of the vehicle and its vibration sound generation method according to the multiple target abnormal scenes, and controlling at least one target motor to perform abnormal reminder according to the corresponding vibration sound generation method.

[0010] According to the above technical means, the preset alarm priority rule based on the scene is used as an important basis for resource allocation and determining the alarm trigger order when facing multiple simultaneous alarm situations, ensuring that the most urgent and important alarms can be processed and prompted first.

[0011] According to an embodiment of the present application, at least one target motor of the vehicle and its vibration sound generation method are matched according to the actual scenario, and at least one target motor is controlled to perform an abnormal reminder according to the corresponding vibration sound generation method, including: when the actual scenario is a collision warning scenario, controlling a plurality of target motors of the vehicle to vibrate with a first target sound, wherein the frequency of the first target sound is higher than a first preset frequency; when the actual scenario is a lane departure scenario, controlling at least one target motor of the vehicle to vibrate to generate a second target sound, wherein the frequency of the second target sound is lower than a second preset frequency, and the second preset frequency is lower than the first preset frequency.

[0012] According to the above technical means, a high-frequency continuous sound is generated in a collision warning scenario to arouse the high alertness of the driver, and a low-frequency pulsed sound is generated in a lane departure scenario to gently remind the driver to perform a correction operation. This design of differential sound waves can not only effectively distinguish different types of alarm situations, but also help the driver accurately judge the type of risk faced by the vehicle in the first time, so as to take corresponding countermeasures.

[0013] According to an embodiment of the present application, when matching at least one target motor of the vehicle and its vibration sound generation method according to the actual scenario, and controlling at least one target motor to perform an abnormal reminder according to the corresponding vibration sound generation method, it further includes: obtaining the in-vehicle noise information of the vehicle; adjusting the vibration sound generation parameters of at least one target motor according to the in-vehicle noise information.

[0014] According to the above technical means, automatically adjusting the vibration sound generation parameters of the motor according to the in-vehicle noise ensures that the alarm reminder sound can maintain sufficient clarity and penetration in various noisy environments, effectively solving the problem that the alarm system in the related art has poor alarm effect in high-noise environments.

[0015] According to an embodiment of the present application, before controlling at least one target motor to perform an abnormal reminder according to the corresponding vibration sound generation method, it includes: obtaining the status information of at least one target motor; when it is determined according to the status information that one or more of at least one target motor are in a failure state, matching at least one spare motor in the vehicle and its spare vibration sound generation method according to the actual scenario, and controlling at least one spare motor to perform an abnormal reminder according to the spare vibration sound generation method.

[0016] According to the above technical means, the working status of each motor is monitored in real time. When it is found that a certain target motor fails, the spare motor is immediately started, and the sound generation mode and parameters are readjusted to ensure the continuous and stable operation of the alarm function, improving the reliability and redundancy of the alarm reminder.

[0017] According to an embodiment of the present application, controlling at least one target motor to perform abnormal reminder according to the corresponding vibration sound generation method includes: determining the power supply voltage and the preset pulse width modulation signal of each target motor based on the vibration sound generation method; during the process of supplying power to the target motor through the power supply voltage, controlling a phase winding in the target motor to be energized based on the preset pulse width modulation signal to control the target motor to vibrate and generate sound.

[0018] According to the above technical means, the target motor is controlled to vibrate and generate sound through the power supply voltage and the pulse width modulation signal, so that the sound generation intensity and frequency of the target motor can be adjusted by controlling the amplitude of the power supply voltage and the frequency of the pulse width modulation signal, improving the alarm flexibility.

[0019] A controller includes a memory, a processor, and a vehicle abnormal reminder program stored on the memory and executable on the processor. When the processor executes the vehicle abnormal reminder program, the above-mentioned vehicle abnormal reminder method is implemented.

[0020] A vehicle abnormal reminder device includes: an acquisition module for acquiring the status information of the vehicle and collecting the environmental information of the current environment where the vehicle is located; an identification module for identifying the actual scene where the vehicle is located according to the status information and the environmental information and judging whether the actual scene meets the preset abnormal reminder condition; a control module for, when the actual scene meets the preset abnormal reminder condition, matching at least one target motor of the vehicle and its vibration sound generation method according to the actual scene, and controlling at least one target motor to perform abnormal reminder according to the corresponding vibration sound generation method.

[0021] A vehicle includes the above-mentioned controller or the above-mentioned vehicle abnormal reminder device.

[0022] Advantages of the present invention:

[0023] (1) Improvement in alarm redundancy: Multiple motors of the vehicle are used as backups for each other, and a single point of failure does not affect the overall alarm function. Since a plurality of motors work together, even if one or more motors fail, the other motors can still continue to undertake the alarm task, avoiding the risk of the entire alarm system failing due to a single motor failure, significantly improving the reliability and redundancy of the abnormal reminder, and providing a more solid guarantee for vehicle safety.

[0024] (2) Environmental adaptability: Dynamically adjust the sound generation parameters to ensure that the alarm sound can be recognized in a noisy environment. By real-time monitoring of the in-vehicle environmental noise and adjusting the motor vibration parameters accordingly, the alarm reminder sound can always adapt to the current environmental conditions. Whether on a quiet rural road or a noisy urban street, it can ensure that the driver clearly receives the abnormal reminder, effectively improving the practicability and applicability of the vehicle abnormal reminder.

[0025] (3) User experience optimization: Different alarm types are distinguished by differentiated sound waves (such as high-frequency / low-frequency combinations). Different alarm types correspond to specific sound wave characteristics. The driver can quickly and accurately judge the cause of the alarm through characteristics such as the frequency, rhythm, and intensity of the sound, without having to distract too much attention to identify complex alarm signals, so as to be able to focus more on dealing with various situations during driving, improving driving safety and comfort.

[0035] The following will illustrate the embodiments of the present invention with reference to the drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0036] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0037] The vehicle abnormal reminder method, controller, vehicle abnormal reminder device, and vehicle proposed in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0038] It is a flowchart of a vehicle abnormal reminder method according to an embodiment of the present application.

[0039] As Figure 1 shown, the vehicle abnormal reminder method of the embodiments of the present application includes:

[0040] S1, obtaining the status information of the vehicle and collecting the environmental information of the current environment where the vehicle is located;

[0041] S2, identifying the actual scene where the vehicle is located according to the status information and environmental information, and determining whether the actual scene satisfies the preset abnormal reminder condition;

[0042] S4, if the preset abnormal reminder condition is satisfied, matching at least one target motor of the vehicle and its vibration and sound generation mode according to the actual scene where the vehicle is located, and controlling at least one target motor to perform abnormal reminder according to the corresponding vibration and sound generation mode.

[0043] Specifically, the status information of the vehicle and the environmental information of the current environment where the vehicle is located can be obtained through various types of on-vehicle sensors, such as collision sensors, noise sensors, lane departure sensors, lidar, on-vehicle cameras, etc. These sensors can monitor various states of the vehicle and the surrounding environmental information in real time. Once an abnormal situation is detected, such as the vehicle has a collision risk, tire pressure abnormality, lane departure, or other potential dangerous situations, it is determined that the actual scene where the vehicle is located satisfies the preset abnormal reminder condition and abnormal reminder is required.

[0044] The preset abnormal reminder condition can be set according to the actual situation to determine whether there is an abnormality in the actual scene where the vehicle is located for reminder. For example, based on the environmental image collected by the camera, it is judged whether the vehicle is driving over the line. If the vehicle is driving over the line, it is determined that lane departure has occurred, the preset abnormal reminder condition is satisfied, and at least one target motor corresponding to lane departure and its vibration and sound generation mode are matched; based on the point cloud data collected by the lidar, vehicle collision is predicted. If there is a vehicle collision risk, the preset abnormal reminder condition is satisfied, and at least one target motor corresponding to vehicle collision and its vibration and sound generation mode are matched.

[0045] The target motor can cover various motors in the passenger compartment, such as window motors, seat adjustment motors, sunroof motors, etc., as Figure 2 shown. These motors are used for their respective control functions under normal circumstances. When performing abnormal reminder control, different frequencies and rhythms of sound waves are generated by making them vibrate on their own through corresponding control methods, so as to achieve the abnormal reminder function. Since the vibration characteristics of each motor are different, vibrations with specific frequencies and amplitudes can be generated, providing a basis for the diversification of alarm sound waves.

[0046] The mapping relationship between the abnormal reminder scenario, the target motor, and its vibration sound generation method can be pre-stored. When it is determined that the actual scenario of the vehicle meets the preset abnormal reminder condition, at least one target motor of the vehicle and its vibration sound generation method are matched based on the mapping relationship according to the abnormal reminder scenario corresponding to the actual scenario, and then at least one target motor is controlled to perform abnormal reminder according to the corresponding vibration sound generation method. In addition, the mapping relationship between the corresponding target motor and its vibration sound generation method can also be set based on the preset abnormal reminder condition, and the corresponding target motor and its vibration sound generation method are found according to the preset abnormal reminder condition satisfied by the actual scenario, so as to be used for abnormal reminder matching the actual scenario of the vehicle.

[0047] This embodiment allocates the corresponding motor combination and vibration sound generation method according to the actual scenario of the vehicle. For example, in the scenario of collision warning reminder, the target motors include window motors and seat motors. The window motors and seat motors are simultaneously driven to vibrate and generate sound. Through the cooperation of multiple motors, a stronger and more easily recognizable alarm effect is produced; while in the scenario of lane departure, a smaller number of motors are selected, such as using window motors as the target motors, and the window motors are controlled to vibrate and generate sound by themselves. Thus, the effectiveness of the alarm reminder is ensured, the vehicle resources are reasonably utilized, and unnecessary energy consumption and equipment wear are avoided.

[0048] In summary, this embodiment controls at least one target motor to perform cooperative vibration according to the preset vibration mode and parameters. Different motor combinations can generate sound waves with different frequencies, amplitudes, and rhythms. Through the superposition and combination of these sound waves, a unique and distinguishable abnormal reminder sound is formed, which can not only effectively distinguish different types of abnormal reminder situations, but also help the driver accurately judge the type of risk faced by the vehicle in the first time, so as to take corresponding countermeasures. And this method uses the existing motor equipment in the vehicle as a redundant means of alarm, gives full play to the potential functions of various motors inside the vehicle, and realizes the optimal allocation of resources and the deep integration of functions.

[0049] In some embodiments of the present application, matching at least one target motor of the vehicle and its vibration and sound generation method according to the actual scenario includes: determining an alarm signal according to the actual scenario; determining the level of the alarm signal according to the preset alarm priority corresponding to the actual scenario; and matching at least one target motor of the vehicle and its vibration and sound generation method based on the level of the alarm signal.

[0050] That is to say, when it is determined that the actual scenario meets the preset abnormal reminder condition, a corresponding alarm signal is generated. The alarm signal includes key information such as the alarm type and the degree of urgency, so as to accurately identify and process the signal.

[0051] After receiving the alarm signal, first, according to the preset priority rule in the dynamic priority database, search for the preset alarm priority corresponding to the actual scenario. The dynamic priority database stores multiple target abnormal scenarios and the preset alarm priority corresponding to each target abnormal scenario. When it is determined that the actual scenario meets the preset abnormal reminder condition, according to the target abnormal scenario matched by the actual scenario, the preset alarm priority corresponding to the target abnormal scenario is obtained as the preset alarm priority corresponding to the actual scenario. Then, determine the level of the alarm signal according to the preset alarm priority of the actual scenario.

[0052] According to the different alarm levels, select the corresponding number and type of motor combinations and vibration and sound generation methods to achieve the alarm function. For example, for a high-priority collision alarm signal, multiple motors such as the window motor and the seat motor may be called simultaneously for collaborative vibration and sound generation to produce a strong and obvious alarm effect; while for a low-priority lane departure alarm signal, a single or fewer motors such as the sunroof motor may be selected for vibration alarm to avoid excessive interference with the driver.

[0053] In some embodiments of the present application, when the actual scenario meets multiple preset abnormal reminder conditions, it further includes: determining multiple target abnormal scenarios corresponding to the actual scenario, where the target abnormal scenario corresponds to the preset abnormal reminder condition; determining the alarm trigger order based on the preset alarm priority corresponding to the target abnormal scenario; and according to the alarm trigger order, matching at least one target motor of the vehicle and its vibration and sound generation method according to the target abnormal scenario, and controlling at least one target motor to perform abnormal reminder according to the corresponding vibration and sound generation method.

[0054] That is to say, the preset abnormal reminder condition is used to judge whether the actual scenario is in the target abnormal scenario. For example, the preset collision reminder condition can be determined based on the collision warning scenario, the preset lane departure reminder condition can be determined based on the lane departure scenario, and the preset tire pressure abnormal reminder condition can be determined based on the tire pressure abnormal scenario.

[0055] Multiple target abnormal scenarios and the corresponding preset alarm priorities for each target abnormal scenario are pre-stored in the database. The preset alarm priorities corresponding to each target abnormal scenario are sorted according to the urgency and importance of the alarm. For example, in the field of vehicle safety, the alarm priority of collision warning is higher than that of tire pressure abnormality, and the alarm priority of tire pressure abnormality is higher than that of lane departure. When it is determined that the actual scenario meets multiple preset abnormal reminder conditions, the multiple target abnormal scenarios corresponding to the actual scenario are determined according to the preset abnormal reminder conditions met by the actual scenario, and the preset alarm priorities corresponding to the multiple target abnormal scenarios are retrieved based on the database to determine the alarm trigger order. Suppose it is determined that the actual scenario includes a collision warning scenario and a tire pressure abnormality scenario. Then, first, at least one target motor of the vehicle and its vibration and sound generation method are matched according to the collision warning scenario, and at least one target motor is controlled to perform collision warning abnormal reminder according to the corresponding vibration and sound generation method. Then, at least one target motor of the vehicle and its vibration and sound generation method are matched according to the tire pressure abnormality scenario, and at least one target motor is controlled to perform tire pressure abnormality reminder according to the corresponding vibration and sound generation method.

[0056] Based on the setting of the preset alarm priority, this embodiment enables reasonable allocation of resources when facing multiple simultaneous abnormal situations, which is an important basis for determining the alarm trigger order, ensuring that the most urgent and important alarms can be processed and prompted first.

[0057] In some embodiments of the present application, matching at least one target motor of the vehicle and its vibration and sound generation method according to the actual scenario, and controlling at least one target motor to perform abnormal reminder according to the corresponding vibration and sound generation method includes: when the actual scenario is a collision warning scenario, controlling multiple target motors of the vehicle to vibrate to generate a first target sound, where the frequency of the first target sound is higher than a first preset frequency; when the actual scenario is a lane departure scenario, controlling at least one target motor of the vehicle to vibrate to generate a second target sound, where the frequency of the second target sound is lower than a second preset frequency, and the second preset frequency is lower than the first preset frequency.

[0058] Specifically, this abnormal reminder method can control multiple motors to perform collaborative vibration according to preset vibration modes and parameters. Different motor combinations can generate sound waves with different frequencies, amplitudes, and rhythms. Through the superposition and combination of these sound waves, unique and distinguishable alarm sounds are formed.

[0059] When it is determined that the actual scenario is a collision warning scenario, when giving a collision reminder, control multiple target motors to generate a high-frequency continuous sound, that is, a first target sound with a frequency higher than the first preset frequency, to arouse the high alertness of the driver. When it is determined that the actual scenario is a lane departure scenario, when giving a lane departure reminder, control at least one target motor to generate a low-frequency pulse sound, that is, a second target sound with a frequency lower than the second preset frequency, to gently remind the driver to perform a correction operation. This design of differentiated sound waves can not only effectively distinguish different types of abnormal situations, but also help the driver accurately judge the type of risk faced by the vehicle in the first time, so as to take corresponding countermeasures.

[0060] This embodiment distinguishes abnormal types through differentiated sound waves (such as high-frequency / low-frequency combinations). Different abnormal scenario types correspond to specific sound wave characteristics. The driver can quickly and accurately judge the reason for the alarm through characteristics such as the frequency, rhythm, and intensity of the sound, without having to distract too much attention to identify complex alarm signals, so as to be able to focus more on dealing with various situations during driving, improving the safety and comfort of driving.

[0061] In some embodiments of the present application, when matching at least one target motor of the vehicle and its vibration and sound generation method according to the actual scenario, and controlling at least one target motor to give an abnormal reminder according to the corresponding vibration and sound generation method, it further includes: obtaining the in-vehicle noise information of the vehicle; adjusting the vibration and sound generation parameters of at least one target motor according to the in-vehicle noise information.

[0062] Specifically, the vehicle alarm reminder system adopted by the related technology completes the reminder action through an alarm speaker, and there is a problem that the alarm effect of the alarm system is not good in a high-noise environment. For example, when the vehicle is driving in a noisy environment such as a traffic jam, a construction area, or a large event site, the sound of the alarm speaker is easily covered by the surrounding environmental noise, and the driver cannot clearly identify the alarm signal, resulting in missing important safety information.

[0063] To solve the above technical problems, the environmental noise detection unit of the vehicle monitors the noise level in the passenger compartment in real time, and dynamically adjusts the vibration and sound generation parameters of the target motor according to the detection data combined with a preset environmental adaptive algorithm, so as to adjust the reminder sound. The specific formula can be: I = I0×(1 + N / Nmax), where I represents the adjusted motor amplitude, I0 is the initial amplitude, N is the current environmental noise value, and Nmax is the preset maximum noise threshold. That is to say, when the environmental noise is large, the vibration intensity of the motor is correspondingly increased to enhance the penetration and recognizability of the reminder sound; while when the environmental noise is small, the vibration intensity is appropriately reduced to balance the alarm effect and driving comfort, ensuring that the alarm prompt can be clearly conveyed without causing unnecessary trouble to the driver.

[0064] This dynamic adjustment mechanism ensures that the abnormal reminder sound can still be clearly distinguishable in a noisy environment, effectively solving the problem of poor alarm effect of the alarm system in the related technology in a high-noise environment. It can adapt to complex and changeable actual road conditions and environmental conditions, meet the safety alarm requirements of the vehicle in various scenarios, and ensure that clear and reliable alarm prompts can be provided for the driver under various conditions.

[0065] In some embodiments of the present application, before controlling at least one target motor to perform abnormal reminder according to the corresponding vibration sound generation method, it includes: obtaining the status information of at least one target motor; when determining that one or more of the at least one target motors are in a failure state according to the status information, matching at least one spare motor and its spare vibration sound generation method in the vehicle according to the actual scenario, and controlling at least one spare motor to perform abnormal reminder according to the spare vibration sound generation method.

[0066] That is to say, the status information of each motor is monitored in real time, and the status information may include motor current, motor voltage, current working status, etc.

[0067] When determining that one or more of the at least one target motors are in a failure state according to the status information, for example, the target motor is in a working state or a fault occurs, it is considered that the target motor fails and cannot be used for abnormal reminder. Automatically switch to the spare motor and adjust the sound generation mode. For example, determine the spare motor according to the situation of the remaining motors combined with the actual scenario, and re-adjust the sound generation mode and parameters to ensure the continuous and stable operation of the alarm function, improving the overall reliability and redundancy of the system. The application of this spare vibration sound generation method can, on the one hand, perform abnormal reminder for the current actual scenario, and on the other hand, facilitate the driver to identify the motor fault based on the spare vibration sound generation method, so as to facilitate the timely detection of the vehicle motor.

[0068] Furthermore, when determining that one or more of the at least one target motors are in a failure state, the failed target motor can be replaced by the spare motor, so as to combine the effective target motors and spare motors to perform abnormal reminder sound according to the spare vibration sound generation method, or the original target motor combination can be entirely replaced by the spare motor combination, and then control the spare motor combination to perform abnormal reminder sound according to the spare vibration sound generation method, without specific limitation.

[0069] In some embodiments of the present application, controlling at least one target motor to perform abnormal reminder according to the corresponding vibration sound generation method includes: determining the power supply voltage and the preset pulse width modulation signal of each target motor based on the vibration sound generation method; during the process of supplying power to the target motor through the power supply voltage, controlling one phase winding of the target motor to be energized based on the preset pulse width modulation signal to control the target motor to vibrate and generate sound.

[0070] That is to say, by controlling the supply voltage and the preset pulse width modulation signal, the target motor can generate self-vibration sound without rotation, so that the sound intensity and frequency of the target motor can be adjusted by controlling the voltage amplitude of the supply voltage and the signal frequency of the preset pulse width modulation signal, improving the flexibility of sound control for alarm reminder.

[0071] As a specific embodiment of the present application, as Figure 3 shown, the vehicle abnormal reminder method may include the following steps:

[0072] S101, continuously monitor the status information of the vehicle and the environmental information of the environment where the vehicle is located through in-vehicle sensors.

[0073] S102, identify the actual scene where the vehicle is located according to the status information and environmental information.

[0074] S103, determine whether the actual scene meets the preset abnormal reminder condition. If so, execute step S104; if not, execute step S101.

[0075] S104, match at least one target motor of the vehicle and its vibration sound generation method according to the actual scene.

[0076] S105, determine whether there is a failure in the matched target motor. If so, execute step S106; if not, execute step S107.

[0077] S106, match at least one spare motor in the vehicle and its spare vibration sound generation method according to the actual scene.

[0078] S107, obtain the in-vehicle noise value of the vehicle.

[0079] S108, adjust the motor amplitude I = I0×(1 + N / Nmax).

[0080] S109, control the motor to perform abnormal reminder according to the corresponding vibration sound generation method based on the adjusted motor amplitude.

[0081] This abnormal reminder method can effectively solve the single-point failure problem of the alarm system in the related technology, make full use of the existing vehicle resources to achieve redundant alarm functions, and have good environmental adaptability, ensuring that clear and reliable alarm prompts can be provided for the driver under various conditions. Specifically, through key technologies such as environmental noise detection, dynamic priority control, and multi-motor collaborative sound generation, the high reliability, environmental self-adaptability, and user-friendliness of the alarm function are realized, effectively improving the safety performance of the vehicle.

[0082] Furthermore, the abnormal reminder system structure corresponding to this abnormal reminder method is as Figure 4 shown, including the following modules:

[0083] 1. Multi-motor module: It includes various motors in the passenger compartment, such as window motors, seat adjustment motors, sunroof motors, etc. Under normal circumstances, these motors are used for their respective control functions, but in this system, through specific control methods, they vibrate to generate sound waves with different frequencies and rhythms, thereby realizing the alarm reminder function.

[0084] 2. Control module: As the core part of the system, it includes a main control unit and a communication unit, which are located within the domain controller. The main control unit is responsible for receiving alarm signals from the sensor module and, according to the preset control logic and priority rules, precisely controls the multi-motor module, including selecting appropriate motor combinations, determining vibration parameters, etc. The communication unit is responsible for transmitting data and instructions between various components, ensuring the coordinated operation of all parts of the system, and realizing real-time interaction and efficient processing of information.

[0085] 3. Sensor module: It contains various types of sensors, such as collision sensors, noise sensors, lane departure sensors, etc. These sensors can real-time monitor various states of the vehicle and surrounding environment information. Once an abnormal situation is detected, such as a vehicle collision, excessive surrounding environment noise, vehicle lane departure, etc., it immediately generates corresponding alarm signals and transmits them to the control module, providing a basis for the system's alarm decision-making.

[0086] 4. Dynamic priority database: This database stores the priority rules for different alarm scenarios, and sorts various possible alarm situations according to the urgency and importance of the alarm. For example, in the field of vehicle safety, the priority of collision alarm is higher than that of tire pressure abnormal alarm, and the priority of tire pressure abnormal alarm is higher than that of lane departure alarm, etc. These priority rules are an important basis for the system to reasonably allocate resources and determine the alarm trigger order when facing multiple simultaneous alarm situations, ensuring that the most urgent and important alarms can be processed and prompted first.

[0087] 5. Environmental noise detection unit: It is responsible for real-time monitoring the noise level in the passenger compartment and feeding back the monitoring data to the control module. The control module, based on these data and combined with the preset environment adaptive algorithm, dynamically adjusts the sound generation intensity of the motor to ensure that the alarm sound can still be clearly distinguishable in a noisy environment, effectively solving the problem of poor alarm effect of traditional alarm systems in high-noise environments.
