Further details and advantages of the present invention will become apparent from the detailed description provided hereinafter. It is to be understood that the following drawings are merely illustrative and not drawn to scale and are not to be considered limiting of the application, the detailed description being made with reference to the accompanying drawings, in which:
fig. 1 shows a flowchart of a method for implementing a departure alert, according to an embodiment of the present invention.
Detailed Description
Embodiments of the present invention are described below with reference to the drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of, and enabling description for, those skilled in the art. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. Furthermore, it should be understood that the invention is not limited to the specific embodiments described. Rather, any combination of the features and elements described below is contemplated as carrying out the invention, whether or not they relate to different embodiments. Thus, the following aspects, features, embodiments and advantages are merely illustrative and are not considered elements or limitations of the claims except where explicitly recited in a claim.
Fig. 1 shows a flowchart of a method for implementing a departure alert, according to an embodiment of the present invention. The vehicle simultaneously supports communication with the RFID key through a radio frequency communication technology and communication with the mobile intelligent device through a Bluetooth communication technology.
As shown in fig. 1, first, when the entire vehicle is not powered off, the vehicle is stationary, and all doors are closed, the door state is detected. If any vehicle door is detected to be opened, whether the mobile intelligent device is in an effective range is detected through a Bluetooth communication technology, namely, whether the distance between the mobile intelligent device and the vehicle is not larger than a set first threshold value is detected. If the detection result is yes, the departure reminding is not triggered; if the detection result is negative, whether the RFID key is in the effective range is detected through the radio frequency communication technology, namely whether the distance between the RFID key and the vehicle is not larger than a set second threshold value is detected. If the detection result is yes, the departure reminding is not triggered; and if the detection result is negative, triggering the vehicle leaving reminding. The specific values of the first threshold and the second threshold can be defined according to actual conditions.
Specifically, the vehicle can be in radio frequency communication connection with the RFID key through a low-frequency antenna array and a vehicle-mounted high-frequency receiver which are arranged around the vehicle body, so that the position of the RFID key is detected, and the legality of the RFID key is authenticated. Radio waves radiated by the low-frequency antenna array can be sensed by the RFID key, and the RFID key feeds back RSSI (Received Signal Strength Indication) to the vehicle-mounted high-frequency receiver through high-frequency radio waves, so that the relative position of the RFID key is detected.
Specifically, the vehicle can realize bluetooth communication connection with the mobile intelligent device through a bluetooth communication module integrated in the T-box or an independent bluetooth communication module. In a specific embodiment, the independent bluetooth communication module comprises a master module arranged in the vehicle (for example, arranged in the center of the vehicle, in the armrest box or higher) and a plurality of slave modules arranged in the vehicle and outside the vehicle (for example, arranged in the vehicle near the trunk and around the outside of the vehicle), wherein the master module and the slave modules are used for detecting bluetooth signal strength indications sent by the mobile intelligent device, and the master module is further used for calculating the positioning result of the mobile intelligent device according to the detected bluetooth signal strength indications.
In particular, the departure alert may include an audible and visual alert issued by the vehicle and/or an alert issued by the mobile smart device APP. For example, the audible and visual warning sent by the vehicle can be a text message and a sound prompt sent by an instrument panel in the vehicle, a light sent by a steering lamp of the vehicle, a sound sent by a horn of the vehicle, and the like. In addition, the mobile intelligent device APP can also send out text or voice reminding.
After the departure reminding is triggered, the positions of the RFID key and the mobile intelligent device are continuously detected, and the departure reminding is cancelled if the mobile intelligent device is detected to be in the effective range or the RFID key is detected to be in the effective range.
After canceling the departure warning, if it is detected that all the doors are closed, the flow ends. If not, the RFID key and the mobile intelligent device need to be located continuously, and the departure reminding is triggered again when the mobile intelligent device and the RFID key are detected to be out of the effective range.
In summary, in the invention, for the situation that the vehicle supports communication with the RFID key and communication with the mobile intelligent device at the same time, a complete solution is provided to realize the departure reminding, thereby filling the gap in the prior art. By utilizing the technical scheme of the invention, the reminding of leaving the vehicle can be realized while ensuring that the user can normally use the mobile intelligent device and the traditional RFID key to enter the vehicle.
In addition, those skilled in the art can understand that the method for realizing the departure reminding provided by the invention is also suitable for the situation that the vehicle only supports the communication with the mobile intelligent device through the Bluetooth communication technology.
For example, the door state is detected when the entire vehicle is not powered down, the vehicle is stationary, and all doors are closed. If any vehicle door is detected to be opened, whether the mobile intelligent device is in an effective range or not is detected through a Bluetooth communication technology, namely, whether the distance between the mobile intelligent device and the vehicle is not larger than a set threshold value or not is detected. If the detection result is yes, the departure reminding is not triggered; and if the detection result is negative, triggering the vehicle leaving reminding. After the departure reminding is triggered, if the mobile intelligent device is detected to be in the effective range, the departure reminding is stopped.
It should be noted that the above description is only an example and not a limitation of the present invention. In other embodiments of the invention, the method may have more, fewer, or different steps, and the order, inclusion, or functional relationship between the steps may be different from that described and illustrated. For example, in general, multiple steps may be combined into a single step, or a single step may be split into multiple steps. For a person skilled in the art, the sequence of the steps is not changed without creative efforts and is within the protection scope of the invention.
The technical solution of the present invention may be substantially implemented or partially implemented in the prior art, or all or part of the technical solution may be implemented in a software product, which is stored in a storage medium and includes several instructions to enable a computer device (which may be a personal computer, a server, or a network device) or a processor or a microcontroller to execute all or part of the steps of the method according to the embodiments of the present invention.
Those of ordinary skill in the art will understand that: all or a portion of the steps of implementing the above-described method embodiments may be performed by hardware associated with program instructions. The program may be stored in a computer-readable storage medium. When executed, the program performs steps comprising the method embodiments described above; and the aforementioned storage medium includes: various media that can store program codes, such as ROM, RAM, magnetic or optical disks.
