Description

Technical Field

[0001] The present invention relates to the technical field of vehicle Bluetooth communication, in particular to a vehicle dual Bluetooth system based on a vehicle control system. Background Art

[0002] With the development of new energy vehicles, the demand for intelligent technology is increasing. Among the solutions for unlocking cars, keyless entry and starting are becoming more and more popular among consumers. Among them, the unlocking function based on Bluetooth is becoming more and more common, which is realized by interacting with the car's data through a mobile phone APP. The mobile phone APP connects to the vehicle through Bluetooth, binds the vehicle information, and records the vehicle's Bluetooth. When the user approaches the vehicle with the mobile phone, the mobile phone and the vehicle's Bluetooth are connected, and the senseless unlocking function is realized through logical judgment.

[0003] With the development of intelligent vehicles, Bluetooth technology is increasingly being used in the automotive field. Traditional automotive Bluetooth systems usually have only a single function: either for sensor unlocking the vehicle or for data exchange with mobile apps. Such single-function Bluetooth systems have certain limitations. For example, in the sensor unlocking scenario, if it also takes on the task of data transmission, the unlocking response may be delayed due to high data traffic, affecting the user experience. In terms of data transmission, if the Bluetooth module is shared with the sensor unlocking, the stability and accuracy of data transmission may be affected due to frequent interference of the unlocking signal.

[0004] In addition, the mobile phone has a function that forcibly closes applications running in the background. When the vehicle Bluetooth is used as the connection host, it cannot search for the mobile phone Bluetooth device as the slave. As a result, when the user holds the mobile phone close to the vehicle, the Bluetooth is not connected to the vehicle and cannot be unlocked without feeling, which shows a quality problem of functional failure. Therefore, it is of great practical significance to develop a dual-Bluetooth system for vehicles that can separate the induction unlocking and data transmission functions and stably realize the unlocking function. Summary of the Invention

[0005] The object of the present invention is to provide a vehicle dual Bluetooth system based on a vehicle control system to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a vehicle dual Bluetooth system based on a vehicle control system, comprising:

[0007] The induction unlocking Bluetooth module is responsible for communicating with the Bluetooth-enabled device carried by the user to realize the induction unlocking of the vehicle;

[0008] Data transmission Bluetooth module, used for data transmission with device application software, realizing information interaction between vehicle and device, including vehicle status data upload function and device command reception function;

[0009] The vehicle control system is the core of the entire dual Bluetooth system. It is responsible for coordinating the work of the induction unlocking Bluetooth module and the data transmission Bluetooth module, receiving instructions sent by the induction unlocking Bluetooth module and the data transmission Bluetooth module, and controlling various devices of the vehicle according to the received instructions, specifically including Bluetooth module management, instruction processing, and data storage and management.

[0010] Preferably, the vehicle status data uploading function and the device instruction receiving function are specifically:

After receiving the commands, the data transmission Bluetooth module forwards the commands to the vehicle control system, and the vehicle control system performs corresponding operations according to the commands.

[0013] Preferably, the Bluetooth module management, instruction processing, and data storage and management are specifically as follows:

[0014] Bluetooth module management: Initialize and configure the induction unlocking Bluetooth module and the data transmission Bluetooth module to ensure the normal operation of the two modules;

[0019] Step 2: Determine whether the sensorless unlocking function is turned on. If so, turn on both the unlocking Bluetooth and data Bluetooth broadcasting. Otherwise, only turn on the data Bluetooth broadcasting.

[0020] Step 3: Determine whether the data Bluetooth is connected. If so, wake up the vehicle control system to determine whether there is a mobile phone command for the vehicle control system to process, or the vehicle control system has data or control instructions for the mobile phone to process. If so, process it; otherwise, go directly to step 4;

[0021] Step 4: Determine whether the unlocking Bluetooth is connected. If so, send the Bluetooth signal strength to the vehicle control system for processing. After completion, return to step 3 for loop processing. Otherwise, return to step 3.

[0022] Preferably, the inductive unlocking Bluetooth module includes inductive unlocking and inductive locking, and depends on the unlocking Bluetooth signal strength. An unlocking instruction is generated according to the change of the Bluetooth signal strength. After receiving the instruction, the vehicle control system completes the Bluetooth unlocking process.

[0023] Preferably, the induction unlocking Bluetooth module works as follows:

[0024] When the Bluetooth device carried by the user enters the effective sensing range of the vehicle's induction unlocking Bluetooth module, the induction unlocking Bluetooth module will automatically detect the Bluetooth signal of the device;

[0025] The induction unlocking Bluetooth module compares the detected Bluetooth signal with the legal Bluetooth device information pre-stored in the vehicle control system;

[0026] If the comparison result matches, when a Bluetooth signal is received, the distance between the Bluetooth device and the vehicle is calculated based on the Bluetooth signal strength, and an unlocking command is sent to the vehicle control system.

[0027] Preferably, the Bluetooth unlocking process includes the following steps:

[0028] Step 1: Determine whether the Bluetooth signal strength is received. If so, determine whether the user is approaching the vehicle based on the change in Bluetooth signal strength and perform the unlocking action. Otherwise, remain unchanged.

[0029] Step 2: If the Bluetooth signal strength is received but does not meet the proximity unlock condition, determine whether the user has pressed the unlock button. If so, determine whether the signal strength meets the signal strength of the unlock button. If so, unlock the phone. Otherwise, proceed to step 3.

[0030] Step 3: Determine whether the vehicle is powered on. If it is powered on, the unlocking process will be carried out. If not, the automatic locking process will be carried out in step 4.

[0031] Step 4: Determine whether the signal strength is out of the induction unlocking range. If so and it lasts for one minute, then execute the lock, otherwise go to step 5;

[0032] Step 5: Determine whether the signal strength is within the locking range, and if so, execute the locking end.

[0033] Preferably, the vehicle unlocking process is performed while the vehicle is powered on, and after the vehicle is unlocked, the data transmission Bluetooth module and the vehicle control system continue to complete data interaction and device operation.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] The present invention realizes data transmission function and senseless unlocking function, such as approach unlocking, leaving unlocking, and key unlocking, through dual Bluetooth systems and a set of reasonable unlocking judgment logic;

[0050] The present invention will be further described below in conjunction with Examples 1 to 3:

[0051] Example 1:

[0052] This embodiment is used to describe the specific implementation of the vehicle system Bluetooth connection and data processing process. The following is a detailed description of the four steps:

[0053] Step 1: The vehicle control system is powered on for initialization and reads the saved Bluetooth parameters and function parameters;

[0054] Step 2: Determine whether the sensorless unlocking function is turned on. If so, turn on both the unlocking Bluetooth and data Bluetooth broadcasting. Otherwise, only turn on the data Bluetooth broadcasting.

[0055] Step 3: Determine whether the data Bluetooth is connected.

[0057] Example 2:

[0058] This embodiment is used to describe the working method of the induction unlocking Bluetooth module. The induction unlocking Bluetooth module includes non-sensing unlocking and non-sensing locking, and depends on the unlocking Bluetooth signal strength. The unlocking command is generated according to the change of Bluetooth signal strength. The vehicle control system processes the received command after receiving it. The specific method is as follows:

[0059] When the Bluetooth device carried by the user enters the effective sensing range of the vehicle's induction unlocking Bluetooth module, the induction unlocking Bluetooth module will automatically detect the Bluetooth signal of the device;

[0060] The induction unlocking Bluetooth module compares the detected Bluetooth signal with the legal Bluetooth device information pre-stored in the vehicle control system;

[0061] If the comparison result matches, when a Bluetooth signal is received, the distance between the Bluetooth device and the vehicle is calculated based on the Bluetooth signal strength, and an unlocking command is sent to the vehicle control system.

[0062] Example 3:

[0063] The specific implementation of the Bluetooth unlocking process in this embodiment is described in detail in five steps:

[0064] Step 1: Determine whether the Bluetooth signal strength is received. If so, determine whether the user is approaching the vehicle based on the change in Bluetooth signal strength and perform the unlocking action. Otherwise, remain unchanged.

[0065] Step 2: If the Bluetooth signal strength is received but does not meet the proximity unlock condition, determine whether the user has pressed the unlock button. If so, determine whether the signal strength meets the signal strength of the unlock button. If so, unlock the phone. Otherwise, proceed to step 3.

[0066] Step 3: Determine whether the vehicle is powered on. If it is powered on, continue with the subsequent operations of the unlocking process. If it is not powered on, enter the automatic locking process of step 4;

[0067] The vehicle unlocking process is performed during the vehicle power-on process. After the vehicle is unlocked, the data transmission Bluetooth module and the vehicle control system continue to complete data interaction and device operations.

[0068] Step 4: Determine whether the signal strength is out of the induction unlocking range. If so and it lasts for one minute, then execute the lock, otherwise go to step 5;

[0069] Step 5: Determine whether the signal strength is within the locking range, and if so, execute the locking end.

[0070] Working principle: When the present invention is used, the vehicle control system is first powered on for initialization, and reads the saved Bluetooth parameters and functional parameters. After the senseless unlocking function is turned on, the unlocking Bluetooth and data Bluetooth broadcasts are turned on at the same time. Otherwise, only the data Bluetooth broadcast is turned on. The data transmission Bluetooth module can transmit data with the mobile phone APP to realize information interaction between the vehicle and the device, and the induction unlocking Bluetooth module can communicate with the mobile phone with Bluetooth function carried by the user to realize the induction unlocking of the vehicle. After connecting the unlocking Bluetooth, the Bluetooth signal strength will be sent to the vehicle control system, and the unlocking instruction will be sent according to the Bluetooth unlocking process. After the data Bluetooth of the unlocked vehicle is connected, the vehicle control system will be awakened to determine whether there is a mobile phone instruction for the vehicle control system to process, or the vehicle control system has data or control instructions for the mobile phone to process, and coordinate the work of the induction unlocking Bluetooth module and the data transmission Bluetooth module.
