In order to make the objects, technical solutions and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely a subset of embodiments of the invention and not all embodiments of the invention, with the understanding that the invention is not limited to the example embodiments described herein. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the invention described herein without inventive step, shall fall within the scope of protection of the invention.
With the development of bluetooth technology, more and more bluetooth devices are installed at the vehicle-mounted end. For example, the bluetooth car charger has functions of charging and bluetooth connection, is popular with drivers, and is almost a standard product of car electronic devices. The Bluetooth technology can not only realize data and energy transmission, but also have other wireless functions, particularly electronic fence functions, can play a certain role in safe driving, can effectively realize large-range and high-accuracy early warning in the driving process, can bring a good and interesting use body for a user, and provides the use viscosity of the user.
Based on the above consideration, the embodiment of the invention provides a safe driving assistance method based on bluetooth. Referring to fig. 1, fig. 1 is a flowchart illustrating a safe driving assistance method based on bluetooth according to an embodiment of the present invention. As shown in fig. 1, the method 100 includes:
firstly, in step S110, a user not connected with bluetooth is detected through bluetooth scanning, and a driving speed is obtained;
in step S120, when the unconnected bluetooth user is detected, determining whether to issue a first alarm prompt according to the driving speed, and detecting a received signal strength indication of the unconnected bluetooth user;
finally, in step S130, a second warning alert or a third warning alert is issued according to the received signal strength indication and the driving speed.
In the driving process, whether unconnected Bluetooth users exist around is scanned by using a Bluetooth technology, the distance between the surrounding Bluetooth users and a driving vehicle can be judged by receiving signal strength indication when the Bluetooth users are detected, when the received signal strength indication is stronger, the attenuation of the Bluetooth signals is reduced, the unconnected Bluetooth users are closer to the driving vehicle, and on the contrary, when the received signal strength indication is weaker, the attenuation of the Bluetooth signals is large, the unconnected Bluetooth users are farther from the driving vehicle, so that the distance of surrounding objects (such as vehicles or people) is indirectly reflected by the received signal strength indication. In addition, different levels of alarm are carried out by combining the received signal strength indication and the driving speed so as to remind a driver; through the alarm of different grades, the distance and the change of the surrounding objects can be intuitively sensed for driving, the blind area of the driver and negligence caused by other reasons are effectively made up, the safe driving auxiliary function is realized, and the safety of the driver is effectively ensured.
The safe driving auxiliary method based on Bluetooth according to the embodiment of the invention can be deployed at a personal terminal, such as a smart phone, a tablet computer, a personal computer, etc.; it may also be deployed at the vehicle device end, such as a bluetooth vehicle charger or the like.
According to the safe driving assistance method based on the Bluetooth, provided by the embodiment of the invention, whether vehicles, pedestrians and distances exist around the vehicles, pedestrians and the distances between vehicles and pedestrians are indirectly reflected through the scanning function of the Bluetooth and the received signal strength indication reading capacity in the driving process, so that blind areas and unpredictable negligence of a driver are effectively compensated, a safe driving assistance effect is realized, and the safety of the driver is greatly ensured.
According to an embodiment of the present invention, in step S110, the acquiring the driving speed may further include: directly detecting the driving speed or acquiring the driving speed from a connected Bluetooth user.
Optionally, the directly detecting the driving speed comprises: detecting the driving speed based on a GPS.
In one embodiment, for example, where the method 100 is deployed in a cell phone (personal terminal), the cell phone detects the driving speed of the vehicle via its own GPS.
Optionally, the obtaining the driving speed from the connected bluetooth user comprises: detecting a Bluetooth user in the vehicle through Bluetooth scanning, and establishing Bluetooth connection; detecting the driving speed by a connected Bluetooth user establishing the Bluetooth connection; and acquiring the driving speed.
In one embodiment, taking the method 100 deployed in a bluetooth car charger, for example, an in-car bluetooth user is a mobile phone, acquiring the driving speed from a connected bluetooth user includes:
the Bluetooth vehicle-mounted charger detects a mobile phone in a vehicle through Bluetooth scanning and establishes Bluetooth connection with the mobile phone;
the mobile phone detects the driving speed through a GPS and sends the driving speed to the Bluetooth vehicle-mounted charger.
It should be understood that the above-mentioned mobile phone is only an example, and the driving speed can also be detected by using other speed measuring devices. The invention is not limited by the speed measuring method specifically adopted, and the speed measuring method can be applied to the safe driving auxiliary method based on the bluetooth in the embodiment of the invention, no matter the existing speed measuring method or the speed measuring method developed in the future, and the invention also belongs to the protection scope of the invention.
According to the embodiment of the present invention, in step S120, determining whether to issue a first warning alert according to the driving speed includes:
when the driving speed is in a preset high speed range, a first alarm prompt is sent out; and/or when the driving speed is in a preset low speed range, not sending out a first alarm prompt.
If the vehicle runs in a high-speed scene, once unconnected Bluetooth users are detected around, it is indicated that objects exist around, and then the driver needs to be reminded in time in view of the fact that the vehicle runs at a high speed, the driving speed is high, the possibility of safety accidents is high, the time is short, and therefore the driver can be reminded in time, and therefore when the vehicle runs at a high speed, the unconnected Bluetooth users can send out alarm reminding to inform the driver. And if the vehicle runs in a low-speed scene, the running speed is relatively low, a driver has more time to react when running at a relatively high speed, when unconnected Bluetooth users are detected to exist around, the alarm reminding can be temporarily not sent out, and the unconnected Bluetooth users are further judged and then processed.
In one embodiment, the first warning reminder or a warning reminder different from the first warning reminder may also be issued when the driving speed is in a preset low speed range.
It should be understood that the preset high speed range and the preset low speed range may be set according to actual needs, and are not limited herein. And the invention is not limited by the specifically adopted Received Signal Strength Indication (RSSI) detection method, and no matter the existing RSSI detection method or the future developed RSSI detection method, the invention can be applied to the bluetooth-based safe driving assistance method according to the embodiment of the invention, and shall also be included in the protection scope of the invention.
According to the embodiment of the present invention, in step S130, issuing a second warning alert or a third warning alert according to the received signal strength indication and the driving speed includes:
when the driving speed is in a preset high speed range, a second alarm prompt is sent out; and/or sending out a third alarm prompt when the driving speed is in a preset low speed range.
Optionally, the second alarm reminder comprises a second sub-alarm reminder divided into s +1 levels according to s level thresholds; and/or the presence of a gas in the gas,
the third alert reminder includes a third sub-alert reminder that is classified into t +1 levels according to t level thresholds.
Optionally, the second and/or third alert alerts comprise: and (6) voice prompt. Wherein different levels of sub-alert reminders in the second alert reminder and/or the third alert reminder may be distinguished using different voices or different forms of music. For example, relatively sharp music may be used to indicate that the unconnected bluetooth users are closer, while relatively slow music may be used to indicate that the unconnected bluetooth users are farther.
Optionally, the s level thresholds are the same as or different from the t level thresholds, and/or s is the same as or different from t.
When the received signal strength indication of the unconnected Bluetooth user is greater than or equal to the nth grade threshold value, sending out a sub-alarm prompt of n +1 grade, wherein n is less than or equal to s or t; and when the received signal strength indication of the unconnected Bluetooth user is smaller than the minimum level threshold value, sending out a first level sub-alarm prompt. The second alarm prompt and the third alarm prompt may be the same or different, that is, the same alarm prompt may be used during high-speed driving and during low-speed driving, or different alarm prompts may be used; when different alarms are used for reminding, only the grade threshold values are different, only the grade number is different, or the grade threshold values and the grade number are different, it should be understood that n, s and t are natural numbers, and the grade threshold values and the grade number can be set as required without limitation.
In one embodiment, the level threshold of the second alarm reminder may be lower than the level threshold of the third alarm reminder. Because the safety factor in the high-speed driving environment is lower than that in the low-speed driving environment, the grade threshold value in the high-speed driving process can be set to be lower than that in the low-speed driving process, so that the driver can be reminded in advance, and the safety of the driver is further ensured.
According to an embodiment of the invention, the method 100 further comprises:
performing at least one of disarming, validating, or validating at a specified time for at least one of the first alert reminder, the second alert reminder, or the third alert reminder.
The user may also have multiple types of permissions for all the alert reminders in the above embodiments of the present invention, such as releasing the alert reminder, and/or determining whether the alert reminder is effective, and/or when the alert reminder is effective, so as to avoid interference of frequent and incorrect alert reminders to the driver.
Next, the method 100 will be described by taking high-speed travel as an example. The safe driving auxiliary method based on the Bluetooth comprises the following steps:
firstly, a Bluetooth vehicle-mounted charger detects a mobile phone in a vehicle through Bluetooth scanning and establishes Bluetooth connection with the mobile phone; the mobile phone detects the driving speed through a GPS and sends the driving speed to a Bluetooth vehicle-mounted charger;
then, the Bluetooth vehicle-mounted charger acquires the driving speed, automatically judges that the vehicle is in a high-speed driving scene, and detects the unconnected Bluetooth user through Bluetooth scanning;
when the user without the Bluetooth connection is detected (such as the Bluetooth name is scanned), a first voice alarm prompt is sent out to prompt the driver that other vehicles or people are around under the current high-speed driving environment. Simultaneously, the RSSI is detected, and a second alarm prompt is sent out according to the RSSI, wherein the RSSI is detected and specifically comprises the following steps:
assuming that the second alarm reminder comprises second sub-alarm reminders divided into s +1 levels according to s level thresholds, the s level thresholds being incremented and the corresponding s +1 level second sub-alarm reminders being music of increasing urgency;
comparing the RSSI of the unconnected Bluetooth user with the s level thresholds, and if the RSSI of the unconnected Bluetooth user is greater than or equal to the nth level threshold (n is less than s), sending out a sub-alarm prompt of n +1 level, wherein n is less than or equal to s; if the received signal strength indication of the unconnected Bluetooth user is smaller than a 1 st level threshold value, sending a first level sub-alarm prompt;
in addition, the user can perform at least one of disarming, validation, or validation at a specified time on the first voice warning reminder and/or the second warning reminder to avoid interference of frequent and false warnings with the driver.
Therefore, according to the safe driving assistance method based on the Bluetooth, whether vehicles, pedestrians and the distance between the vehicles and the pedestrians exist around the vehicle and the distance between the vehicles and the pedestrians are indirectly reflected through the scanning function of the Bluetooth and the received signal strength indication reading capacity in the driving process, interaction with a mobile phone of a driver or reminding of the Bluetooth vehicle-mounted charger is achieved, blind areas and unpredictable negligence of the driver are effectively made up, the safe driving assistance effect is achieved, and safety of the driver is greatly guaranteed.
The method 100 will be described below by taking low-speed running as an example. The safe driving auxiliary method based on the Bluetooth comprises the following steps:
firstly, a Bluetooth vehicle-mounted charger detects a mobile phone in a vehicle through Bluetooth scanning and establishes Bluetooth connection with the mobile phone; the mobile phone detects the driving speed through a GPS and sends the driving speed to a Bluetooth vehicle-mounted charger;
then, the Bluetooth vehicle-mounted charger acquires the driving speed, automatically judges that the vehicle is in a low-speed driving scene, and detects the unconnected Bluetooth user through Bluetooth scanning;
when detecting the unconnected Bluetooth user (for example, scanning the Bluetooth name), detecting the RSSI of the unconnected Bluetooth user, and sending a third alarm prompt according to the RSSI of the unconnected Bluetooth user, specifically including:
assuming that the third alarm reminder comprises a third sub-alarm reminder divided into t +1 levels according to t level thresholds, the t level thresholds being incremented, and the corresponding t +1 level third sub-alarm reminder being music that is increasingly urgent;
comparing the RSSI of the unconnected Bluetooth user with the t level thresholds, and if the RSSI of the unconnected Bluetooth user is greater than or equal to the nth level threshold (n is less than t), sending out a sub-alarm prompt of n +1 level, wherein n is less than or equal to t; if the received signal strength indication of the unconnected Bluetooth user is smaller than a 1 st level threshold value, sending a first level sub-alarm prompt;
in addition, the user can perform at least one of releasing, confirming, or taking effect at a designated time on the first voice warning reminder and/or the third warning reminder to avoid interference of frequent and wrong warnings with the driver.
Therefore, according to the safe driving assistance method based on the Bluetooth, whether vehicles, pedestrians and the distance between the vehicles and the pedestrians exist around the vehicle and the distance between the vehicles and the pedestrians are indirectly reflected through the scanning function of the Bluetooth and the received signal strength indication reading capacity in the driving process, interaction with a mobile phone of a driver or reminding of the Bluetooth vehicle-mounted charger is achieved, blind areas and unpredictable negligence of the driver are effectively made up, the safe driving assistance effect is achieved, and safety of the driver is greatly guaranteed.
In addition, according to the safe driving auxiliary method based on the Bluetooth, different alarm reminding modes can be adopted according to different driving environments; under a high-speed driving scene, as long as an unconnected Bluetooth user indicates that vehicles or people exist around the unconnected Bluetooth user, a first alarm prompt is sent out; then, the distance between surrounding vehicles or pedestrians and the user is estimated according to the detected received signal strength indicator RSSI of the unconnected Bluetooth user, and the distance is compared with a preset grade threshold value to send out alarm reminders of different grades; in the ground speed driving scene, when detecting that the unconnected Bluetooth users indicate that vehicles or people exist around, not sending out a first alarm prompt; and then, after the distance between the surrounding vehicles or pedestrians and the user is estimated according to the detected received signal strength indicator RSSI of the unconnected Bluetooth user, different levels of alarm reminding are sent out by comparing the distance with a preset level threshold value.
