In one embodiment, the sensing module includes: a motion trajectory sensing unit, configured to detect information related to the motion trajectory of the mobile terminal.

In one embodiment, the relevant information about the motion trajectory of the mobile terminal specifically includes: acceleration and vibration frequency generated during the motion of the mobile terminal.

In one embodiment, the first wireless communication module includes: at least one of a Bluetooth module, a wifi module, and a Z-Bee module.

The present invention provides a vehicle connection system, which includes: a vehicle wireless communication device and at least one mobile terminal described in the above embodiments. Wherein, the vehicle-mounted wireless communication device includes a second wireless communication module that matches the first wireless communication module in the mobile terminal. That is, the communication device in the vehicle should be of the same type as the communication device in the mobile terminal.

The connection method between the mobile terminal and the vehicle-mounted equipment of the present invention is shown in Figure 2. In the connection method of the present invention, at least the following steps: detect the motion state of the mobile terminal; if the mobile terminal is in the driving state, start the mobile terminal in the mobile terminal. A first wireless communication module; the first wireless communication module establishes a communication connection with the second wireless communication module in the vehicle equipment.

Specifically, the current motion state of the mobile terminal can be detected by the sensing module provided in the mobile terminal, and if the detected motion state meets the standard of the driving state, the control module in the mobile terminal will open the first wireless communication module in the mobile terminal, Find the corresponding second wireless communication module in the car, and the mobile terminal and the car establish a communication connection with each other through the corresponding communication modules provided respectively. Through the automatic connection between the mobile terminal and the vehicle-mounted equipment, the manual operation of the user is saved, and at the same time The driving safety problem that may be caused by operating the mobile terminal during driving is reduced.

In an embodiment, detecting the motion state of the mobile terminal specifically includes: detecting information related to a motion track of the mobile terminal.

In an embodiment, the information related to the movement track of the mobile terminal specifically includes: acceleration generated during the movement of the mobile terminal.

Specifically, a mobile terminal placed in a running vehicle will definitely produce relative motion, so it can be judged by detecting and collecting relevant information of the mobile terminal's motion trajectory to determine whether the mobile terminal is in a driving state. For example, a car will continue to accelerate in the same direction for a long time during the starting and braking stages. Even when driving at a steady speed, the car body will vibrate at a lower frequency for a long time, and acceleration in the vertical direction will also be generated during the vibration process. Therefore, the acceleration data of the mobile terminal can be collected for a period of time for analysis and processing, and it can be accurately detected whether the mobile terminal is currently in the driving state. When it is detected that the mobile terminal is in the driving state, the mobile terminal and the communication module in the vehicle establish connection. In order to more accurately determine whether it is in the driving state, the vibration frequency of the mobile phone following the vehicle body can also be used as a piece of detection motion trajectory information. The frequency is much higher than the vibration frequency generated by the vehicle during driving. Therefore, it can be judged comprehensively through the acceleration in the same direction and the vibration frequency. When the vibration frequency of the vehicle body exceeds the preset value, it is not in the driving state. On the contrary, it can be further Judging acceleration information.

Specifically, the motion trajectory sensing unit set in the mobile terminal can be an acceleration sensor. The acceleration sensor can identify whether the mobile terminal is in the driving state accurately and quickly. The acceleration sensor can not only detect the relevant data of the acceleration in the horizontal direction during motion, but also Detect data related to vibration generated during mobile terminal movement. Whether the car drives the mobile terminal to accelerate or decelerate, the acceleration has obvious characteristics. Moreover, even in the process of driving at a steady speed, the body will generate low-frequency vibrations, so the part of the acceleration sensor that detects vibrations is configured with a lower sampling frequency, which can detect the user's state well. At the same time, this type of sensor has the advantages of low power consumption and little impact on the user's standby time when detecting the motion state of the mobile terminal. Compared with turning on the wireless communication module all the time, for example, turning on Bluetooth requires a few milliamperes of standby current, while the acceleration sensor only has less than 1 milliampere, so the use of sensor detection will reduce a lot of energy consumption and prolong the standby time.

In one embodiment, after establishing the communication connection between the first wireless communication module and the second wireless communication module in the vehicle-mounted device, the method further includes: if the mobile terminal is not in a driving state, shutting down the first wireless communication module in the mobile terminal.

Specifically, when the sensing module does not collect relevant data about the movement of the mobile terminal within a period of time, that is, when the mobile terminal is in a non-driving state, the control module in the mobile terminal will turn off the first wireless communication module in the mobile terminal. The first communication module in the terminal is then connected to the vehicle-mounted communication device through open communication. When in a non-driving state, the communication module of the mobile terminal is turned off in time to reduce unnecessary power consumption.

In one embodiment, if the first wireless communication module is disconnected from the second wireless communication module, the first wireless communication module in the mobile terminal is turned off.

Specifically, when the control module has detected that the communication device in the mobile terminal has been disconnected from the vehicle-mounted communication device, the communication device in the mobile terminal is turned off, so that the number of communication devices in the mobile terminal due to disconnection can be reduced. Still continue to work and the waste problem of the mobile terminal electric power that produces.

In an embodiment, before detecting the motion state of the mobile terminal, it further includes: pairing the first wireless communication module and the second wireless communication module, and saving the pairing information.

Specifically, if the communication device of the mobile terminal has not been connected to the communication device in the car before, at this time, it is necessary to pair the mobile terminal and the communication device in the car once, and the pairing can be performed by performing a communication connection. When the mobile terminal After the first successful connection with the communication device in the car, the mobile terminal and the communication device in the car save the pairing information, and can directly and automatically connect next time without pairing again. Saving the pairing information reduces the need for future connections. Unnecessary operation.

It should be noted that the communication method between the mobile terminal and the car in the present invention is not just a Bluetooth communication connection, and the existing short-distance communication connection methods can be applied to the present invention, for example, wifi connection, Z-Bee connection Ways and so on, as long as the communication module in the mobile terminal and the communication module in the car support the same connection method, supporting multiple connection methods increases the range of applications and also increases the space for users to choose.

The above content is a further detailed description of the present invention in conjunction with specific embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions; Under the premise of , some simple deduction or replacement can also be made, which should be regarded as belonging to the protection scope of the present invention.
