[0011] Beneficial effects of the present disclosure: In the related scheme, the alarm is triggered from three dimensions, and the alarm method is improved. The three dimensions are the seat belt unfastened signal (not the final confirmed seat belt unfastened signal), vehicle speed, and time. The present disclosure uses vehicle speed and time to characterize the vehicle use scenario. For example: Vehicle use scenario: The vehicle is reversing at a low speed (vehicle speed characterization), the driver and passengers have a low demand for seat belts, and the user does not wear a seat belt. At this time, the vehicle will not sound an alarm, avoiding aggravating the tension of the driver and passengers when reversing, and improving the driving experience. In the present disclosure, in combination with the specific vehicle use scenario, the corresponding alarm method is triggered to alarm, which replaces the driving experience of the driver and passengers.

[0017] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0018] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0019] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0020] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0021] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0022] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0023] At present, the seat belt reminder strategy is: when the seat belt is detected to be unfastened and the vehicle is detected to be stationary, the seat belt unfastened indicator light is always on; when the vehicle is detected to be moving, the seat belt unfastened indicator light is always on or flashes, accompanied by a sound reminder. This seat belt unfastened reminder strategy uses a unified alarm strategy regardless of the vehicle usage scenario, resulting in a poor user experience.

[0024] In view of this, the present disclosure proposes a seat belt unfastened alarm method, device and medium. On the basis of the traditional single-dimensional judgment of whether the seat belt is fastened, the vehicle speed and time dimensions are added to characterize the specific vehicle usage scenario. The present disclosure adopts different alarm methods in combination with the specific vehicle usage scenario to effectively improve the driving experience of the driver and passengers.

[0025] Figure 1 FIG. 1 is a flow chart showing a method for warning a seat belt not being fastened according to some embodiments of the present disclosure. Figure 1 As shown, the seat belt unfastened alarm method includes steps 110 to 130.

[0026] In step 110, it is determined whether the seat belt is not fastened by means of the seat belt warning switch, and it is determined whether there is someone sitting in the seat by means of the seat sensor.

[0027] In step 120 , if it is determined that the seat belt is not fastened and that someone is sitting on the seat, it is determined whether the current vehicle speed is less than a first vehicle speed threshold.

[0028] In step 130 , if the current vehicle speed is less than the first vehicle speed threshold, the seat belt unfastened indicator light is always on, and no sound alarm is given.

[0029] If the front vehicle speed is less than the first vehicle speed threshold, the seat belt unfastened indicator light is always on, and no sound alarm is issued. The method also includes: if the vehicle speed is greater than or equal to the first vehicle speed threshold for the first time, the seat belt unfastened indicator light flashes and a sound alarm is issued, wherein the frequency of the sound alarm is a first frequency, and a timer is triggered at the same time.

[0030] If the vehicle speed is greater than or equal to the first vehicle speed threshold for the first time, the seat belt unfastened indicator light flashes and a sound alarm is sounded, and the method also includes: within a preset time, if the vehicle speed is maintained above the first vehicle speed threshold, the seat belt unfastened indicator light keeps flashing and the sound alarm is kept on; when the preset time is exceeded, the seat belt unfastened indicator light is adjusted from flashing to constantly on, the sound alarm is turned off, and the time counting is stopped.

[0031] In some embodiments, if the vehicle speed is greater than or equal to a first speed threshold for the first time, the seat belt unfastened indicator light flashes, and after a sound alarm is issued, it also includes: within a preset time, if the vehicle speed is greater than or equal to a second speed threshold and less than the first speed threshold, the frequency of the sound alarm is adjusted to a second frequency, and the seat belt unfastened indicator light is kept flashing, wherein the second speed threshold is less than the first speed threshold, and the second frequency is less than the first frequency; if the vehicle speed is less than the second speed threshold, the sound alarm is stopped, and the seat belt unfastened indicator light is adjusted from flashing to constantly on.

[0032] The above principle is explained below through a specific embodiment: after determining that the seat belt is not fastened, it is also necessary to judge the two dimensions of vehicle speed and time. Based on the judgment result, the corresponding alarm method is triggered. The alarm method mainly includes two methods. One method is to alarm by the seat belt unfastened indicator light being always on or flashing, and the other method is to alarm by sound. There are two frequencies of sound alarm.

[0033] In this embodiment, the first vehicle speed threshold is set to 20 km / h, the second vehicle speed threshold is set to 10 km / h, and the preset time is set to 95 seconds.

[0034] After determining that the seat belt is not fastened through the seat sensor and the seat belt alarm switch, the system detects whether the current vehicle speed is within 20km / h. If the current vehicle speed is within 20km / h, the seat belt unfastened indicator light will remain on and no sound alarm will be given.

[0035] When the vehicle speed (the vehicle speed at this time is a general concept) reaches 20km / h for the first time, or exceeds 20km / h for the first time, the seat belt unfastened indicator light is adjusted from normally on to flashing, and the sound alarm is turned on with a first frequency, which is 4Hz in this embodiment, and the time timing is triggered at the same time.

[0036] When the vehicle speed remains above 20 km / h for the next 95 seconds, the seat belt unfastened indicator light will keep flashing and the alarm will sound. Once the speed exceeds 95 seconds, the seat belt unfastened indicator light will stay on, the alarm will stop sounding, and the timer will stop counting.

[0037] When the vehicle speed reaches 20km / h for the first time, or exceeds 20km / h for the first time, within the subsequent 95 seconds, if the vehicle speed is between 10km / h and 20km / h, the frequency of the sound alarm will be adjusted from 4Hz to 2Hz, and the seat belt unfastened indicator light will flash.

[0038] When the vehicle speed reaches 10km / h, the sound alarm stops and the seat belt unfastened indicator light stays on.

[0039] Readers are reminded again that they can imagine the following vehicle usage scenario: when the driver (without wearing a seat belt) starts the vehicle and accelerates to 20 km / h, the seat belt unfastened indicator light on the dashboard is always on (hereinafter referred to as the indicator light), and no sound alarm is given; of course, if at this moment, the driver is reversing the vehicle into a parking space at a low speed, no sound alarm is given either, that is, the driver is only in the vehicle usage scenario of reversing the vehicle into a parking space, not in the vehicle usage scenario of moving the vehicle.

[0040] Continuing from above, when the vehicle is started and the speed is accelerated to 20km / h, the indicator light is always on and no sound alarm is sounded. When the driver is moving the vehicle to the parking garage, the speed is 20km / h or more, at this time, the indicator light on the instrument panel changes from always on to flashing, indicating an increase in the danger level. The driver continues to drive, and the speed is always above 20km / h. After driving for 95 seconds (with the first time the speed reaches 20km / h as the time reference node), the indicator light is always on, the alarm is lifted, and the time counting is stopped; within 95 seconds, the indicator light remains flashing and the sound alarm remains.

[0041] In another case, when the vehicle speed reaches 20km / h for the first time, the driver has a strong sense of safety and decelerates immediately. Starting from the moment of deceleration, during the first 95 seconds, the driver controls the vehicle speed between 10km / h and 20km / h. During this first period, the sound alarm frequency decreases from 4Hz to 2Hz, and the indicator light flashes. During the second 95 seconds, the driver controls the vehicle speed below 10km / h and reverses into the garage. At this time, the sound alarm is lifted to avoid aggravating the driver's nervousness, and the reverse parking is completed, thereby completing the entire vehicle moving process.
