Detailed Description
Some non-limiting embodiments of the invention will be described in detail below with reference to the accompanying drawings.
The communication system for the vehicle locking prompt comprises a key terminal system and a vehicle terminal system, wherein the key terminal system comprises a vehicle door state display module and a key terminal communication module, and the vehicle door state display module comprises a warning lamp and a buzzer; the vehicle terminal system comprises a vehicle terminal communication module and a mobile network module. Preferably, the key terminal system further comprises a key control module, and the vehicle terminal system further comprises a vehicle body controller and a lock control module.
FIG. 1 shows an exemplary embodiment of a door status display module of a key fob system, in this example, the door status display module 10 includes a dual color L ED1 and a buzzer 2, but is not limited thereto, e.g., it may also include a graphical display of the door status, L ED1 displays green when the vehicle is in a locked state, L ED1 displays red when the vehicle is in an unlocked state, of course, the L ED1 may be made to display a different color, display a different pattern, or flash in a different pattern, the buzzer 2 functions to initiate an alarm to alert the driver to lock the vehicle when the key is out of range from the vehicle and the vehicle is still in a door open state.
fig. 2 is a schematic diagram showing interaction between a key terminal communication module, a key control module, and a door state display module of the key terminal system, as shown, the key terminal communication module 20 transmits door state information received from a vehicle to the key control module 30, where the door state information is, for example, an open/lock state word, the key control module 30 controls the door state display module 10 to make a corresponding display according to the received open/lock state word, for example, the key control module 30 controls the L ED1 to display green when the open/lock state word indicates that the door is locked, the key control module 30 controls the L ED1 to display red when the open/lock state word indicates that the door is open, and the key control module 30 controls the buzzer 2 to sound an alarm when the distance of the key from the vehicle is out of a valid communication range and the open/lock state word still indicates that the door is open, for example, it may be determined that the distance of the key from the vehicle is out of a valid communication range when the key terminal communication module cannot receive door state information emitted from the vehicle.
Fig. 3 shows a schematic diagram of the interaction between the vehicle body controller of the vehicle terminal system of the communication system for vehicle locking prompt according to the present invention and the lock control module, the vehicle end communication module and the mobile network module. As shown, the vehicle body controller 100 inquires the door state information of the lock control module 40 and transmits the inquired door state information to the vehicle-side communication module 50, and the vehicle-side communication module 50 then transmits the door state information to the key-side communication module 20, thereby communicating between the vehicle-side and the key-side regarding the open/lock state of the door. As described above, the door state information transmitted between the vehicle side and the key side is, for example, an open/lock state word.
In this example, the vehicle-side communication module 50 and the key-side communication module 20 communicate wirelessly using RFID technology. It is clear that a person skilled in the art can also envisage other communication modes in the field between the two, as long as an efficient communication is achieved.
In addition, the vehicle body controller 100 also communicates with the driver's mobile phone through the mobile network module 60. When the vehicle-side communication module 50 cannot detect the key-side communication module 20 and thus cannot transmit information, and the door status information queried by the lock control module 40 still shows that the door is open, the mobile network module 60 will send a message to the driver's mobile phone to indicate that the door is unlocked. Here, the mobile network module and the mobile phone of the driver can communicate by using 4G/5G, and can also communicate by using bluetooth. When the communication is performed through bluetooth, it is also conceivable that the mobile network module sends a warning message to the mobile phone of the driver when it is detected that the mobile phone is away from the vehicle through bluetooth ranging and the door state information queried by the door control module still shows that the door is open.
The communication system for the vehicle locking prompt according to the present invention may further include a vehicle horn and/or vehicle lights. When the vehicle door state information shows that the vehicle door is opened and the distance between the key end communication module and the vehicle end communication module exceeds an effective communication range, the automobile horn can perform whistle alarm and/or light alarm on automobile lamps so as to reinforce the vehicle locking prompt of a driver.
In addition, the invention also relates to a car locking prompting method executed by the communication system for car locking prompting. Fig. 4 shows an exemplary flowchart of the car locking prompting method, which includes the following steps:
S1: the vehicle body controller inquires the state of the vehicle door from the vehicle lock control module, and sends the vehicle door state information indicating that the vehicle door is opened or closed to the vehicle end communication module, and the vehicle end communication module sends the vehicle door state information to the key end communication module;
S2: the key end communication module sends the vehicle door state information to a key control module, if the vehicle door state information shows that the vehicle door is locked, the control module goes to S3, and if the vehicle door state information shows that the vehicle door is opened, the control module goes to S4;
S3: the key control module controls the warning lamp to display green;
S4: the key control module controls the warning lamp to display red;
S5: judging whether the distance between the key and the vehicle exceeds the effective communication range, if so, turning to S6;
S6: the key end control module controls the buzzer to give out sound alarm, and the mobile network module sends warning information to a mobile phone of a driver.
therefore, according to the above non-limiting embodiment of the invention, on one hand, the current unlocking/locking state of the vehicle can be visually displayed to the driver through the two-color LED, on the other hand, the buzzer can be started to give an alarm and simultaneously send a warning message to the mobile phone of the driver through the buzzer under the condition that the vehicle is unlocked and the driver has carried the key away from the vehicle for a certain distance, and the alarm can also be given through the automobile horn and/or the automobile lamp, so that the driver can be reminded in various ways, and the vehicle safety is effectively guaranteed.
The above description of the communication system for a car-lock reminder, the car and the method for a car-lock reminder according to the invention is only exemplary and a person skilled in the art may also envisage other specific implementations without departing from the scope of the invention as defined by the appended claims.
