[0070] The present invention is described below based on the following embodiments, but the present invention is not limited to these embodiments. In the detailed description of the present invention below, certain specific details are described in detail. Those skilled in the art can fully understand the present invention without these details. To avoid obscuring the essence of the present invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0071] Furthermore, persons of ordinary skill in the art will appreciate that the figures provided herein are for illustration purposes only and are not necessarily drawn to scale.

[0072] Unless the context clearly requires otherwise, words like “include”, “comprising” and the like in the specification should be interpreted as including rather than exclusive or exhaustive; that is, as “including but not limited to”.

[0073] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0074] Currently, related technologies typically rely on sensors mounted on the inner wall of the helmet to detect helmet wear, which inevitably requires batteries to be installed inside the helmet. This can cause secondary damage if the helmet is subjected to a severe impact. Furthermore, these sensors cannot detect whether the user is wearing the helmet correctly. Therefore, this embodiment provides a helmet that improves the accuracy of helmet wear detection and vehicle safety.

[0075] Figure 1 Schematic diagram of a helmet according to an embodiment of the present invention. Figure 1As shown, the helmet 1 of this embodiment includes a helmet body 11 and a wearing detection device 12.

[0076] In this embodiment, the helmet body 11 includes a strap buckle 111. The wearing detection device 12 includes a buckle sensor. The buckle sensor is configured to detect the fastening state of the strap buckle. The wearing detection device 12 is configured to detect the helmet wearing state based at least on the fastening state of the strap buckle. Thus, this embodiment detects the helmet wearing state at least by the fastening state of the buckle. This not only detects whether the helmet is being worn, but also whether it is being worn correctly, thereby improving the accuracy of helmet wearing detection and vehicle driving safety.

[0077] In an optional implementation, the wearing detection device 12 is provided at the strap buckle 111, so that the buckle sensor can detect the fastening state of the strap buckle, thereby detecting whether the helmet is worn correctly. Moreover, in this embodiment, since the wearing detection device 12 is provided at the strap buckle 111, there is no need to install electronic devices such as batteries inside the helmet, further improving driving safety. It should be understood that Figure 1 The helmet shown in the figure includes two straps. In other examples, the helmet may include one strap, and the strap buckles are respectively provided at the strap and the edge of the helmet. The wearing detection device can be provided at the buckle at the end of the strap or at the buckle at the edge of the helmet. This embodiment is not limited to this.

[0078] In an optional implementation, the buckle sensor includes a microswitch and / or a Hall sensor. Optionally, the buckle sensor may include only a microswitch or a Hall sensor, or may include both a microswitch and a Hall sensor. The buckle is determined to be engaged if at least one of the microswitch and the Hall sensor detects that the lace buckle is engaged, or it is determined to be engaged only if both the microswitch and the Hall sensor detect that the lace buckle is engaged. This embodiment is not limited to this.

[0079] A microswitch features a small contact gap and a snap-action mechanism. External mechanical force acts on a reed through a transmission element, rapidly connecting or disconnecting the fixed and moving contacts at its ends. If the buckle sensor includes a microswitch, the force generated when the driver puts on the helmet and fastens the buckle quickly opens or closes the microswitch, allowing the buckle's engagement status to be detected.

[0080] A Hall effect sensor is a magnetic field sensor based on the Hall effect. If the buckle sensor includes a Hall effect sensor, when the driver puts on the helmet and fastens the buckle, the change in the Hall effect sensor's electrical signal can be used to determine whether the buckle is engaged.

[0081] In this embodiment, the helmet includes a helmet body and a wearing detection device. The helmet body includes a strap buckle, and the wearing detection device includes a buckle sensor. Thus, in this embodiment, the buckle sensor can detect the fastening state of the strap buckle, and the wearing detection device can detect the helmet wearing state based at least on the fastening state of the strap buckle, thereby improving the accuracy of helmet wearing detection and vehicle driving safety. Furthermore, placing the wearing detection device on the strap buckle avoids placing electrical components such as batteries inside the helmet, thereby preventing secondary injuries and further improving safety.

[0082] Figure 2 FIG2 is a schematic diagram of a wearing detection device according to an embodiment of the present invention. In an optional implementation, the wearing detection device further includes an object detection sensor. The object detection sensor is configured to detect the relative position between the helmet and an object. In other words, the object detection sensor is used to detect the relative position between the helmet and the driver.

[0083] like Figure 2 As shown, the wearing detection device 12 includes a buckle sensor 121 and an object detection sensor 122. Optionally, the buckle sensor 121 includes a micro switch and / or a Hall sensor.

[0084] In one optional implementation, object detection sensor 122 includes one or more of the following sensors: an infrared sensor, a capacitive sensor, and a body temperature sensor. Alternatively, if at least one of all object detection sensors 122 detects that the relative distance between the helmet and the driver is very small, substantially zero, then the driver is determined to meet the helmet-wearing requirement; or if all object detection sensors 122 detect that the relative distance between the helmet and the driver is very small, then the driver is determined to meet the helmet-wearing requirement.

[0085] An infrared sensor, also known as a sensor that uses infrared light, can detect the presence of an object. When a driver wears a helmet correctly, with the buckle and lace engaged, the wear detection device 12 (i.e., the infrared sensor) is in close proximity to the driver's neck, which can be detected by the infrared sensor. Therefore, when the infrared sensor detects an object in close proximity, it indicates that the buckle and lace are in close proximity to the driver's neck, and the driver can be determined to be qualified to wear a helmet.

[0086] Capacitive sensor is a conversion device that converts measured physical quantity or mechanical quantity into capacitance change using various types of capacitors as sensing elements, and is widely used in the measurement of aspects such as displacement, angle, vibration, speed, pressure. In the present embodiment, after correctly wearing the helmet, the buckle lace is in a fastened state, and the wearing detection device 12 is close to the neck position, with a certain pressure. Optionally, the capacitance value of the capacitive sensor can increase as the pressure increases, or can decrease as the pressure decreases. Taking the capacitance value of the capacitive sensor as an example of increasing as the pressure increases, in the present embodiment, when the capacitance value collected by the capacitive sensor is greater than a threshold value, or continues to be greater than the threshold value for a predetermined time, then it shows that the buckle lace is close to the driver's neck position, and now it can be judged that the driver meets the helmet wearing condition.

[0087] The temperature sensor can detect ambient temperature. In this embodiment, when the helmet is properly worn, the buckle strap is engaged, and the wearing detection device 12 is in close proximity to the driver's neck. Consequently, the temperature around the temperature sensor changes accordingly. Therefore, if the temperature detected by the temperature sensor is within a predetermined temperature range, it can be determined that the buckle strap is in close proximity to the driver's neck, and the driver can be determined to be qualified to wear a helmet.

[0088] Optionally, in this embodiment, the buckle sensor and the object detection sensor can be used for detection at the same time, and when the detection results of the buckle sensor and the object detection sensor both meet the conditions, it is determined that the driver is wearing the helmet correctly; or the buckle sensor can be used for detection first, and after the buckle sensor detects that the strap buckle is fastened, the object sensor can be used for detection; or the object sensor can be used for detection first, and after the detection result of the object sensor meets the conditions, the buckle sensor can be used for detection. This embodiment does not limit this.

[0089] The helmet in this embodiment can determine whether the driver is wearing the helmet correctly by comprehensively judging the detection results of the buckle sensor and the detection results of the object detection sensor, further improving the accuracy of helmet wearing detection and driving safety.

[0090] Figure 3 FIG2 is a schematic diagram of another wearing detection device according to an embodiment of the present invention. In an optional implementation, the wearing detection device further includes a posture sensor. The posture sensor is configured to detect whether the helmet is worn correctly by detecting helmet posture information.

[0091] like Figure 3 As shown, the wearing detection device 13 of this embodiment includes a buckle sensor 131, an object detection sensor 132, and a posture sensor 133. Among them, the posture sensor 133 includes a gyroscope and / or an acceleration sensor. The buckle sensor 131 and the object detection sensor 132 are similar to those in the above embodiment and are not repeated here.

[0092] In this embodiment, the wearing detection device 13 can determine whether the driver is wearing the helmet correctly by detecting the relationship between its own movement speed, movement direction and / or helmet wearing angle and vehicle movement information. When the movement direction of the wearing detection device 13 is consistent or substantially consistent with the vehicle movement direction (i.e., the angle difference between the movement directions is less than a predetermined value), and the helmet strap is perpendicular or substantially perpendicular to the vehicle movement direction (i.e., the difference between the angle between the helmet strap and the vehicle movement direction and 90° is less than a threshold value), it is determined that the driver is wearing the helmet correctly.

[0093] Optionally, in this embodiment, the snap sensor, object detection sensor and posture sensor can be used for detection at the same time, and when the detection results of the snap sensor, object detection sensor and posture sensor all meet the conditions, it is determined that the driver is wearing the helmet correctly, or the snap sensor, object detection sensor and posture sensor can be used for detection in sequence. It should be understood that this embodiment does not limit the execution order of the snap sensor, object detection sensor and posture sensor.

[0094] The helmet in this embodiment can determine whether the driver is wearing the helmet correctly by comprehensively judging the detection results of the buckle sensor, the detection results of the object detection sensor and the detection results of the posture sensor, further improving the accuracy of helmet wearing detection and driving safety.

[0095] Figure 4 FIG2 is a schematic diagram of another embodiment of a wear detection device according to an embodiment of the present invention. In an optional implementation, the wear detection device further includes a communication module. The communication module is configured to transmit or broadcast helmet wear status information. Thus, a terminal device or a vehicle central control system can receive the helmet wear status information transmitted or broadcast by the communication module and provide prompts to the driver based on the helmet wear status information.

[0096] like Figure 4 As shown, the wearing detection device 14 of this embodiment includes a buckle sensor 141, an object detection sensor 142, a posture sensor 143 and a communication module 144. The buckle sensor 141, the object detection sensor 142 and the posture sensor 143 are similar to those of the above embodiment and are not described again here.

[0097] The helmet in this embodiment can determine whether the driver is wearing the helmet correctly by comprehensively judging the detection results of the buckle sensor, the detection results of the object detection sensor and the detection results of the posture sensor, and send or broadcast the helmet wearing status information through the communication module to prompt the driver, thereby further improving the accuracy of helmet wearing detection and driving safety.

[0098] Figure 5 This is a flow chart of a helmet wear detection method according to an embodiment of the present invention. In this embodiment, the helmet includes a wear detection device. Optionally, the wear detection device is located at the helmet strap buckle. This eliminates the need for electronic components such as batteries inside the helmet, further improving driving safety.

[0099] The wearing detection device includes a buckle sensor. Optionally, the buckle sensor includes a micro switch and / or a Hall sensor.

[0100] like Figure 5 As shown, in this embodiment, the working process of the wearing detection device in the helmet includes the following steps:

[0101] Step S100: Receive a wearing query instruction. For example, when creating a ride task or during a ride on a shared bicycle or electric motorcycle, the user terminal or the central control of the target vehicle can send a wearing query instruction to the helmet, activating the helmet's wearing detection device to check whether the user is wearing the helmet correctly. Optionally, the helmet's wearing detection device can periodically check the helmet's wearing status based on the detection frequency specified in the configuration information.

[0102] In an optional implementation, the method of this embodiment further includes receiving configuration information. The configuration information includes the activation status and detection frequency of the wear detection device. Optionally, in this embodiment, the server delivers the configuration information in real time. That is, when a user requests to use a shared bicycle or motorcycle, the server, upon receiving the request, searches the corresponding vehicle to determine whether it has a helmet and a wear detection device to determine the configuration information corresponding to the vehicle, and then delivers the configuration information to the helmet in real time.

[0103] In this embodiment, the server stores configuration information and delivers the latest configuration information to the helmet in real time when the helmet is in use. This allows for flexible configuration of the configuration information to adapt to a variety of application scenarios. The configuration information may include, but is not limited to, the activation status and detection frequency of the wear detection device. For example, the configuration information may include: whether to enable the wear detection device (configuration options: yes / no); and the detection frequency of the wear detection device (configuration options: a numerical value, in milliseconds). Thus, upon receiving the wear detection instruction, the helmet can perform a detection based on the configuration information.

[0104] Step S200: Controlling a buckle sensor to detect the fastening state of the helmet strap buckle. In this embodiment, the buckle sensor in the wearing detection device detects whether the helmet buckle strap is fastened. When the buckle strap of the helmet is detected to be fastened, it is determined that the wearing state of the helmet meets the corresponding wearing condition.

[0105] Step S300: Determine the helmet wearing state based at least on the fastening state. In one optional implementation, the helmet is determined to be in the wearing state in response to the strap buckle being in the fastened state. Thus, this embodiment can detect the fastening state of the strap buckle using a buckle sensor, and detect the helmet wearing state based at least on the fastening state of the strap buckle using a wearing detection device, thereby improving the accuracy of helmet wearing detection and vehicle driving safety.

[0106] In another optional implementation, the wearing detection device includes an object detection sensor. Optionally, the object detection sensor includes one or more of the following sensors: an infrared sensor, a capacitive sensor, and a body temperature sensor. The method of this embodiment further includes controlling the object detection sensor to detect the relative position of the helmet and the object.

[0107] Step S300 may specifically include determining the helmet wearing state based on the fastening state of the strap buckle and the relative position of the helmet and the object. Optionally, a detection result of the object detection sensor is determined in response to a wearing condition corresponding to the fastening state of the strap buckle, and the helmet is determined to be in the wearing state in response to the relative position detected by the object detection sensor satisfying the corresponding wearing condition.

[0108] In this embodiment, whether the driver is wearing the helmet correctly can be determined by comprehensively judging the detection results of the buckle sensor and the detection results of the object detection sensor, thereby further improving the accuracy of helmet wearing detection and driving safety.

[0109] In another optional implementation, the wearing detection device includes a posture sensor. Optionally, the posture sensor includes a gyroscope and / or an acceleration sensor. The method of this embodiment further includes: controlling the posture sensor to detect posture information of the helmet.

[0110] Step S300 may specifically include determining the helmet wearing state based on the fastening state of the strap buckle, the relative position between the helmet and the object, and the helmet posture information. Optionally, in response to a wearing condition corresponding to the fastening state of the strap buckle, a detection result of the object detection sensor is determined; in response to the relative position detected by the object detection sensor satisfying the corresponding wearing condition, a detection result of the helmet posture information is determined; and in response to the helmet posture information satisfying the corresponding wearing condition, it is determined that the helmet is in the wearing state.

[0111] In an optional implementation, the method of this embodiment also includes: sending or broadcasting helmet wearing status information so that the terminal device or vehicle central control can obtain the helmet wearing status information, thereby prompting the driver based on the helmet wearing status information.

[0112] The helmet in this embodiment can determine whether the driver is wearing the helmet correctly by comprehensively judging the detection results of the buckle sensor, the detection results of the object detection sensor and the detection results of the posture sensor, and send or broadcast the helmet wearing status information to prompt the driver, thereby further improving the accuracy of helmet wearing detection and driving safety.

[0113] Figure 6 FIG. 1 is a flow chart of another method for detecting helmet wearing according to an embodiment of the present invention. Figure 6 As shown, in this embodiment, the working process of the wearing detection device in the helmet includes the following steps:

[0114] Step S110: Receive a wearing query instruction. Taking a shared bicycle or electric motorcycle as an example, when creating a riding task or during a ride, the user terminal or the central control of the target vehicle can send a wearing query instruction to the helmet to activate the wearing detection device in the helmet to detect whether the user is wearing the helmet correctly.

[0115] Step S120: Buckle sensor detection. In this embodiment, the buckle sensor in the wearing detection device detects whether the buckle strap of the helmet is fastened, and determines that the wearing state of the helmet meets the condition when the buckle strap of the helmet is detected to be fastened.

[0116] Figure 7 Schematic diagram of a helmet in a wearing state according to an embodiment of the present invention. Figure 7 As shown, when the driver wears the helmet correctly, the strap buckle 111 of the helmet is fastened, and the buckle sensor in the wearing detection device 12 generates a fastening signal when the strap buckle is fastened to indicate that the strap buckle of the helmet is fastened.

[0117] Step S130 determines whether the detection result of the buckle sensor meets the first wearing condition. If so, step S140 is executed, which continues the detection using the posture sensor. If not, step S190 is executed, which generates first helmet wearing detection information. The first helmet wearing detection information includes information indicating that the driver is not wearing a helmet or is wearing the helmet incorrectly.

[0118] In this embodiment, in order to avoid the situation where the driver fastens the strap of the helmet but does not wear it, after detecting that the buckle and strap of the helmet are fastened, other sensors are continued to be used for detection to improve the accuracy of helmet wearing detection.

[0119] Step S140, posture sensor detection. In this embodiment, the posture sensor is configured to collect posture information of the helmet. The posture information may include movement information of the wearing detection device and the wearing angle information of the helmet. Optionally, the communication module in the wearing detection device can receive the vehicle posture information collected by the vehicle central control, or can obtain the vehicle posture information by other means, and this embodiment is not limited to this. The wearing detection device is configured to compare the posture information of the helmet and the vehicle posture information to determine whether the second wearing condition is met.

[0120] Optionally, the vehicle movement direction P (x1, y1, z1) and the wearing detection device movement direction H (x2, y2, z2) are collected, and the angle between the vehicle movement direction P and the wearing detection device movement direction H is calculated. When the angle is less than a predetermined threshold T (x0, y0, z0), it is determined that the vehicle and the wearing detection device are moving in the same direction.

[0121] Optionally, the Z-axis data of the gyroscope and gravity sensor are collected, and it is calculated whether the Z-axes of the two are in the same direction (that is, the angle between the Z-axis data of the two is less than a threshold). If the directions are the same, it indicates that the wearing angle information of the helmet meets the correct wearing conditions.

[0122] Step S150 determines whether the detection result of the posture sensor meets the second wearing condition. If the second wearing condition is met, that is, the posture information of the helmet and the posture information of the vehicle meet the relevant conditions, step S160 is executed, that is, the object detection sensor is continued to detect. If the second wearing condition is not met, step S190 is executed, that is, the first helmet wearing detection information is generated. The first helmet wearing detection information includes information indicating that the driver is not wearing a helmet or is wearing the helmet incorrectly.

[0123] Step S160: Object detection sensor detection. In this embodiment, at least one of an infrared sensor, a capacitance sensor, and a body temperature sensor is used to detect whether the wearing detection device is close to the driver. Figure 6 As shown, when the driver wears the helmet, the helmet strap buckle 111 is fastened. At this time, the strap buckle 111 is close to the driver's neck. The infrared sensor will generate relevant signals due to the approach of the object, the capacitance sensor will change the capacitance value due to changes in parameters such as pressure, and the temperature detected by the body temperature sensor will also change. Therefore, at least one of the infrared sensor, the capacitance sensor, and the body temperature sensor can be used for detection to determine whether the current helmet wearing state meets the third wearing condition.

[0124] Step S170 determines whether the detection result of the object detection sensor meets the third wearing condition. If the third wearing condition is met, that is, the infrared sensor detects the proximity of an object, the capacitance value of the capacitive sensor meets the conditions, and / or the temperature of the body temperature sensor is within a predetermined temperature range, step S180 is executed to generate second helmet wearing status information. If the second wearing condition is not met, step S190 is executed to generate first helmet wearing detection information. The first helmet wearing detection information includes information indicating that the driver is not wearing a helmet or is not wearing the helmet correctly. The second helmet wearing detection information includes information indicating that the driver is wearing the helmet correctly.

[0125] This embodiment adopts a method of sequentially detecting the snap sensor, the posture sensor, and the object detection sensor. It should be understood that this embodiment does not limit the detection order of the various sensors.

[0126] The helmet in this embodiment can determine whether the driver is wearing the helmet correctly by comprehensively judging the detection results of the buckle sensor, the detection results of the object detection sensor and the detection results of the posture sensor, further improving the accuracy of helmet wearing detection and driving safety.

[0127] Figure 8 FIG is a schematic diagram of a vehicle system according to an embodiment of the present invention. Figure 8 As shown, the vehicle system 8 of this embodiment of the present invention includes a vehicle central control 81, a helmet 82, and a terminal device 83. The vehicle central control 81 communicates with the wear detection device in the helmet 82 using near-field wireless communication, and the terminal device 83 communicates with the wear detection device in the helmet 82 using near-field wireless communication. Alternatively, the near-field communication method may be Bluetooth, Zigbee, or other communication methods, which are not limited in this embodiment.

[0128] In this embodiment, the helmet 82 includes a helmet body and a wear detection device. The wear detection device includes at least a buckle sensor. Optionally, the wear detection device can be located at the helmet's strap buckle to enhance helmet safety. It should be understood that the helmet 82 in the vehicle system 8 employs the helmet described in the aforementioned embodiment and will not be further described here.

[0129] In this embodiment, the vehicle central control 81 is configured to obtain the wearing status information of the helmet 82 and generate a first prompt message based on the wearing detection status information. In an optional implementation method, the vehicle central control 81 sends a wearing query instruction to the helmet 82 during the process from the creation of the riding task to the end of the riding task to query the wearing status information of the helmet 82. After receiving the wearing query instruction, the helmet 82 enables the wearing detection device, detects the wearing status according to the corresponding configuration information, and sends the detected wearing status information to the vehicle central control 81 through the communication module. The vehicle central control 81 generates a first prompt message based on the received wearing detection status information. In other optional implementation methods, after receiving the wearing query instruction, the helmet 82 enables the wearing detection device and updates the real-time wearing status information to the corresponding broadcast message. The vehicle central control 81 monitors the wireless broadcast of the wearing detection device of the helmet 82 to obtain the wearing status information in the broadcast message.

[0130] In an optional implementation, the first prompt information includes a voice prompt. For example, before the end of the riding task, when the wearing status information shows that the driver has correctly worn the helmet, the vehicle central control 81 voice broadcasts the prompt "Helmet is worn". When the wearing status information shows that the buckle is fastened, but the detection result of the object detection sensor does not meet the conditions, the vehicle central control 81 can voice broadcast the prompt "Helmet buckle is locked, please tighten the strap". When the wearing status information shows that the driver is not wearing a helmet, the vehicle central control 81 voice broadcasts the prompt "Please wear a helmet". At the end of the riding task, the driver takes off the helmet, and the vehicle central control 81 can generate a prompt message based on the real-time motion status of the vehicle and the wearing detection information. For example, when the vehicle is stationary, the vehicle central control 81 voice broadcasts the prompt "Thank you for using the vehicle, please return the helmet first". When the vehicle continues to move, the vehicle central control 81 voice broadcasts the prompt "Please wear the helmet correctly and pay attention to traffic safety".

[0131] In another optional implementation, the vehicle central control 81 also includes a warning light that flashes differently based on different wearing status information. Optionally, the vehicle central control 81 can coordinate voice prompts with warning light prompts to improve information reach. For example, the green light can flash while the voice prompt "Helmet worn" is broadcast, or the red light can flash while the voice prompt "Please wear a helmet" is broadcast.

[0132] In another optional implementation, the first prompt information also includes control information to provide a prompt based on vehicle usage restrictions. The vehicle central control 81 is configured to generate control information based on the wear detection status information to control the vehicle's usage status, thereby providing prompts based on the vehicle's usage status, which includes normal use and restricted use. For example, if the wear status information indicates that the driver is not wearing a helmet correctly, the vehicle may be controlled to have no power output or a speed limit, even if the accelerator is turned, to indicate that the user is not wearing a helmet.

[0133] In this embodiment, the terminal device 83 is configured to obtain the wearing status information of the helmet and generate a second prompt message based on the wearing detection status information of the helmet. In an optional implementation, the terminal device 83 sends a wearing query instruction to the helmet 82 during the process from the creation of the riding task to the end of the riding task to query the wearing status information of the helmet 82. After receiving the wearing query instruction, the helmet 82 enables the wearing detection device and sends the detected wearing status information to the terminal device 83 through the communication module. The terminal device 83 generates a second prompt message based on the received wearing detection status information. In other optional implementations, the helmet 82 enables the wearing detection device after receiving the wearing query instruction and updates the real-time wearing status information to the corresponding broadcast message. The terminal device 83 monitors the wireless broadcast of the wearing detection device of the helmet 82 to obtain the wearing status information in the broadcast message.

[0134] In an optional implementation, the second prompt information includes a pop-up window prompt. For example, when the wearing status information indicates that the driver has correctly worn the helmet, the terminal interface of the terminal device 83 displays a pop-up window message that reads "Helmet is worn." When the wearing status information indicates that the buckle is fastened, but the detection result of the object detection sensor does not meet the conditions, the terminal page of the terminal device 83 displays a pop-up window message that reads "Helmet buckle is locked, please tighten the strap." When the wearing status information indicates that the driver is not wearing a helmet, the terminal page of the terminal device 83 displays a pop-up window message that reads "Please wear a helmet." It should be understood that the terminal device 83 can also provide prompts through voice broadcasts, and this embodiment does not limit the specific prompt method.

[0135] In an optional implementation, the vehicle system 8 of this embodiment further includes a server, wherein the server communicates remotely with the vehicle's central control system 81 and the terminal device. In this embodiment, the server is configured to transmit the helmet's configuration information in real time. That is, the server stores the configuration information and transmits the latest configuration information to the helmet in real time when the helmet is used. This allows for flexible configuration of the configuration information to adapt to a variety of application scenarios. The configuration information may include, but is not limited to, the activation status and detection frequency of the wearing detection device. For example, the configuration information includes: whether to activate the wearing detection device, with configuration options: yes / no; and the detection frequency of the wearing detection device, with configuration options: a numerical value, in milliseconds. Thus, after receiving the wearing detection instruction, the helmet can perform a detection according to the configuration information.

[0136] Optionally, in this embodiment, the terminal device 83 sends a riding request to the server. After receiving the task request, the server detects whether the target vehicle is equipped with a helmet and a wear detection device. If the target vehicle is equipped with a wear detection device, it sends the corresponding configuration information to the helmet 82. After receiving the configuration information, the helmet 82 configures itself accordingly, such as whether to activate the wear detection device and the detection frequency when the wear detection device is activated. Optionally, after configuring itself according to the configuration information, the helmet 82 can provide a voice prompt to the user that the helmet and vehicle are currently available, and send a prompt to the terminal device 83. The terminal device 83 can further prompt the user to start using the helmet or vehicle through interface interaction.

[0137] In this embodiment, a wearing query instruction is sent to the helmet through the terminal device or the vehicle central control, so that the helmet activates the wearing detection device to accurately detect the helmet wearing status information based on the buckle sensor, the posture sensor and the object detection sensor. After the helmet detects the wearing status information, it transmits the wearing status information to the terminal device and the vehicle central control in the form of sending or broadcasting. The terminal device and the vehicle central control generate corresponding prompt information according to the wearing status information to prompt the driver of the vehicle. Therefore, this embodiment can improve the accuracy of helmet wearing detection, and provide prompts based on the terminal device and the vehicle central control to further improve driving safety.

[0138] Figure 9 Flowchart of the information interaction method of the embodiment of the present invention. The information interaction method of the embodiment can be applied to the user's terminal device or the vehicle central control device. Figure 9 As shown, the information interaction method of the embodiment of the present invention includes the following steps:

[0139] Step S210: Acquire helmet wearing status information. The helmet wearing status information is obtained by detecting a wearing detection device in the helmet, which includes at least a buckle sensor. The helmet wearing status information of this embodiment can be determined based on any of the aforementioned embodiments and will not be further described here.

[0140] In an optional embodiment, if a device (terminal device or vehicle central control) sends a helmet wearing query command to the helmet, the helmet wearing status information is obtained by receiving the helmet wearing status information sent by the communication module in the helmet. If the device does not send a helmet wearing query command to the helmet, the helmet wearing status information is obtained by querying the helmet's broadcast information.

[0141] Step S220: Generate prompt information based on the helmet wearing status information.

[0142] Step S230: display or voice broadcast the prompt information.

[0143] In an optional implementation, if the execution subject of this embodiment is a user's terminal device, the prompt information includes the real-time wearing status of the helmet, so that the terminal device generates corresponding prompt information based on the real-time wearing status of the helmet, and displays the prompt information through a pop-up window or announces the prompt information through voice. The manner and content of the terminal device displaying the pop-up window information are similar to those in the above embodiment and will not be repeated here.

[0144] In an optional implementation, if the execution subject of this embodiment is the vehicle's central control system, the prompt information includes the real-time wearing status of the helmet, and the vehicle control information is generated based on the real-time wearing status. Optionally, step S230 can specifically include: displaying the prompt information through lights or announcing the prompt information through voice. For example, a red light can be used to indicate that the helmet is not being worn correctly, while a green light can be used to indicate that the helmet is being worn correctly.

[0145] In an optional implementation, the method of this embodiment further includes controlling the vehicle's usage status based on the prompt information. Optionally, vehicle control information is generated based on the real-time wearing status in the prompt information, and the vehicle's usage status is controlled based on the control information. Optionally, in response to the prompt information indicating that the helmet is not being worn correctly, the vehicle is controlled to be in a restricted usage state. For example, if the wearing status information indicates that the driver is not wearing a helmet correctly, even if the accelerator is turned, the vehicle is controlled to have no power output, or the speed is limited, to indicate that the user is not wearing a helmet.

[0146] This embodiment obtains helmet wearing status information, generates prompt information based on the helmet wearing status information, and displays or voice broadcasts the prompt information to prompt the user of the real-time helmet wearing status, thereby improving driving safety.
