Fig. 3 shows a method according to the invention for alerting by means of a vehicle key. In a first step, the distance state between the vehicle key and the mobile terminal is determined as a function of a communication connection, in particular a bluetooth connection, of the vehicle key to the mobile terminal, which is embodied as a smartphone. According to an exemplary embodiment, the bluetooth module 203 is activated by pressing the bluetooth switch 204 on the vehicle key. Here, it is graphically displayed on the display module 400 that the bluetooth module 203 of the vehicle key has been activated (see fig. 2). If the Bluetooth module 203 can not establish Bluetooth connection with the smart phone, the prompt signal is directly output. If the bluetooth module 203 establishes a bluetooth connection with the smart phone, the distance measurement module of the bluetooth module 203 finds the distance between the vehicle key and the smart phone in real time. In the next step, the vehicle key outputs a reminding signal according to the distance state so as to remind the position of the mobile terminal device relative to the vehicle key. Here, when the smartphone is located more than a certain distance, for example, 15 meters away from the vehicle key, the LED light emitting device 201 of the vehicle key emits flickering light to visually remind the user that the smartphone is forgotten. Additionally or alternatively, it can also be provided that the buzzer 202 of the vehicle key sounds a buzzer sound in order to audibly alert the user that his smartphone is forgotten. In addition or alternatively, it can also be provided that the vibration device of the vehicle key emits a vibration for the purpose of haptic warning the user that his smartphone is forgotten.
It may optionally be provided here that the light-emitting means 201 and/or the buzzer 202 and/or the vibration means of the vehicle key automatically adjust the intensity of the output signal as a function of the state of the distance between the vehicle key and the smartphone. Specifically, as the distance between the vehicle key and the smartphone increases, for example, from 15 meters to 25 meters, the frequency and/or intensity of the flickering light emitted by the light-emitting device 201 gradually increases and/or the color of the flickering light gradually changes. Additionally or alternatively, the beep tone and/or volume of the beep sound emitted by the buzzer 202 is gradually increased and/or the type of beep sound is varied. Additionally or alternatively, the frequency and/or amplitude of the vibrations emitted by the vibration device is gradually increased and/or the vibration pattern is varied. When the distance between the vehicle key and the smartphone exceeds, for example, 30 meters, for example, the bluetooth connection of the bluetooth module 203 to the smartphone is interrupted, the respective flashing light and/or the respective beeping sound and/or the respective vibration emitted by the light emitting device 201 and/or the buzzer 202 and/or the vibrating device are/is the strongest. At the same time, an icon of bluetooth disconnection is displayed and a prompt is displayed in the display module 400 (see fig. 2). The user can thus easily, quickly and intuitively perceive the reminder to forget his smartphone by means of the visually and/or acoustically and/or tactilely perceptible reminder signal and additionally by means of the reminder graphic displayed in the display module 400.
The vehicle key is provided with the communication module, so that the connection function and the use prospect of the vehicle key and other equipment are realized. It should be noted here that the present invention can be applied not only to a scenario in which a user forgets the mobile communication device in a vehicle, but also to a wider scenario, such as a scenario in which a vehicle user forgets the smartphone at a place of dinner when going out.
