Description

Technical Field

[0001] The present invention relates to the field of vehicle anti-theft control, and particularly to a wheel anti-theft control method and system. Background Art

[0002] With the continuous improvement of people's living standards, the popularity of cars is getting higher and higher, and almost every household has a car. People driving or taking cars to go to work or travel have become more and more frequent. Currently, the materials required for vehicle design are getting better and better, especially for the design of new wheels involving the use of high-end and expensive materials, which has led to frequent occurrences of vehicle wheel thefts. There are many solutions to prevent vehicle wheels from being stolen. For example, installing a mechanical lock on each wheel. However, this solution is not very convenient to install, and wheel thieves have also discovered ways to make this mechanical protection ineffective.

[0003] The prior art also adopts the technical route of alarm. After detecting the risk of wheel theft, an alarm signal is sent through an alarm, but there is still the defect that the user cannot be notified in time. At the same time, only monitoring is achieved, and there are no effective measures to reduce or avoid the theft risk, so the solution still lacks in anti-theft effect. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a wheel anti-theft control method and system, which can monitor the risk of wheel theft and send an alarm to the user, and at the same time can further adopt control strategies to deal with the theft risk and reduce the possibility of theft.

[0014] The wheel anti-theft control strategy includes:

[0015] Collect vehicle tilt data. If the vehicle does not tilt, drive the vehicle forward and backward. During the vehicle movement, detect obstacles in the moving direction of the vehicle through the on-vehicle radar and switch the vehicle to move forward or backward based on the distance of the obstacles.

[0016] If the vehicle tilts, collect the tilt direction and / or wheel height information to locate the wheels at risk of theft, and control the rotation of the located wheels at risk of theft.

[0017] The rotation speed of the wheels at risk of theft is less than the set threshold, and the rotation of the wheels is controlled in a variable speed and variable direction manner.

[0022] The following briefly describes the content expressed in each drawing of the present invention specification and the marks in the drawings:

[0023] Figure 1 It is the operation flowchart of the remote wheel anti-theft system of the present invention

[0024] Figure 2 It is the system block diagram of the remote wheel anti-theft function of the present invention. Detailed Embodiments

[0025] The following further elaborates on the specific implementation of the present invention through the description of the optimal embodiments with reference to the accompanying drawings.

[0026] This embodiment provides a wheel anti-theft control solution. Through this solution, the anti-theft of the wheels can be effectively achieved. The anti-theft strategy of this solution includes two aspects: on the one hand, after detecting the risk of theft, through the combination of on-site vehicle alarm warning and driving away and remote alarm reminder to the vehicle owner, the risk reminder of wheel theft is realized; on the other hand, after detecting the risk of theft, the rotation of the vehicle or the wheels is used to prevent the theft from occurring, interfering with the wheel theft and thus reducing the possibility of wheel theft. The specific solution is as follows:

[0027] This embodiment provides a wheel anti-theft control method, including:

[0028] After the vehicle is powered off, a first instruction is collected and obtained, and the anti-theft monitoring process of the wheels is started according to the first instruction;

[0029] During the wheel anti-theft monitoring process, the first information is collected in real time, and the theft risk of the current vehicle is judged based on the first information;

[0030] A second instruction for alarm is generated based on the theft risk of the vehicle;

[0031] The second instruction is executed.

[0032] Among them:

[0033] The first instruction is an instruction for the user to turn on or off the wheel anti-theft function. The first instruction obtained after the vehicle is powered off is issued by the vehicle owner or driver to start the monitoring process. Because the vehicle is generally in the use stage when it is not powered off, and there are people in the vehicle during the use stage, there is no need for anti-theft monitoring. Therefore, it is more reasonable for the vehicle owner to actively start the anti-theft monitoring process after the vehicle is powered off. The first instruction is issued by the user, driver, or vehicle owner. In this embodiment, the first instruction is used by the vehicle owner to turn on and off the wheel anti-theft process through the anti-theft system switch. The anti-theft system switch is set as a soft switch and is set in the user's vehicle networking APP. By the user operating the anti-theft system switch in the mobile phone APP, the switch signal is sent through the mobile phone APP, via the vehicle networking platform and in-vehicle TBOX, and then sent to the domain controller in the vehicle, and the domain controller realizes the monitoring and control of the anti-theft process.

[0034] After starting the anti-theft process, the first information is collected in real time, and the theft risk of the current vehicle is judged based on the first information; the first information is the status information of the monitored wheels, and the theft risk of the current wheels is judged based on the monitoring of the status information of the wheels. The monitoring of the status of the wheels can be realized through a variety of ways to monitor the anti-theft risk, including but not limited to the following ways:

[0035] 1. Collect the heights of the four wheels from the ground through height sensors, and determine whether there is a risk of theft based on the height changes.

[0036] 2. Determine whether there is a risk of theft based on the tilt angles of the four wheels relative to the vehicle body collected by the vehicle tilt sensor or gyroscope.

[0037] 3. Determine whether there is a risk of theft based on the personnel information of those who approach the tires and stay at the tires for a long time collected by the cameras of the vehicle's sentry system.

[0038] Any of the above three methods can achieve the identification and monitoring of the risk of wheel theft. For example, after entering the theft monitoring process, if it is detected that the height of at least one wheel from the ground changes significantly, it may indicate that the vehicle has been jacked up by the thief when stealing the wheel, resulting in a significant change in the wheel height. When the height change is detected, it means that there is a risk of theft at this time. Similarly, when stealing the wheel, it will cause the vehicle to tilt, so the vehicle tilt data can be collected to determine whether there is a risk of theft.

[0039] After the risk of theft is detected, an alarm signal needs to be sent at this time. In this solution, the alarm reminder of the theft risk is realized through the second instruction. The second instruction includes a local alarm instruction and / or a remote alarm instruction. The local alarm instruction is executed to achieve the anti-theft alarm at the vehicle site, and the remote alarm instruction is executed to send an anti-theft alarm to the user remotely. The domain controller generates the second instruction according to the theft risk. When there is a theft risk, the domain controller generates the second instruction, and the second instruction is executed by the in-vehicle alarm and the mobile phone vehicle networking APP respectively. The second instruction is sent to the in-vehicle voice system through the vehicle CAN network, and the in-vehicle voice system executes the second instruction and issues the corresponding theft risk reminder, driving and repelling the thieves through voice alarm, so as to achieve the purpose of theft reminder and driving away the thieves. At the same time, the second instruction is transmitted to the cloud platform TSP through the in-vehicle TBOX, and the cloud platform TSP sends the second instruction to the user's mobile phone APP. After receiving the second instruction, the mobile phone APP executes the second instruction, and displays information such as text, voice, and images of the wheel theft risk reminder through the mobile phone APP to convey the current wheel theft risk to the user and remind the user to pay attention to handling.

[0040] In a preferred solution of this embodiment, after the risk of theft is detected, simply alarming cannot accurately drive away the thieves and cannot effectively protect the vehicle property safety of the vehicle owner. Therefore, this embodiment also sets a wheel anti-theft control strategy to prevent the wheels from being stolen. Specifically:

[0041] When it is determined that there is a risk of theft currently, the vehicle's powertrain system starts, and the wheel anti-theft control strategy is used to prevent the wheels from being stolen. When there is a risk of theft, the occurrence of wheel theft is prevented by the way of wheel movement, thereby protecting the vehicle's property safety. After the risk of theft disappears or is eliminated, the execution of the wheel anti-theft control strategy is stopped.

[0042] The wheel anti-theft control strategy includes:

[0043] Collect vehicle tilt data. If the vehicle does not tilt, drive the vehicle to move forward and backward. During the vehicle movement, detect obstacles in the moving direction of the vehicle through on-vehicle radar and switch the vehicle's forward or backward movement based on the distance to the obstacles. If the vehicle does not tilt, it means that the theft is in the earliest stage at this time, and the vehicle has not been jacked up yet. To interfere with the vehicle being jacked up and prevent the tires from being removed, the vehicle is powered on at this time, and the vehicle is controlled to move automatically forward and backward to prevent the tires from being removed, thereby achieving anti-theft. Controlling the vehicle to move forward and backward requires the vehicle to be powered on and the drive motor to rotate to drive the vehicle to move forward and backward, or the vehicle is ignited and the powertrain system starts to control the vehicle to move forward and backward. At this time, to avoid property losses caused by collisions during the vehicle's forward and backward movement, on-vehicle radar installed at the front and rear of the vehicle is used to detect obstacles in the front and rear directions during the vehicle's forward and backward movement. When the distance between the vehicle and the obstacle is less than the threshold value, the vehicle's forward and backward movement directions are switched according to the distance to the obstacle to ensure that the vehicle will not touch the obstacle during forward and backward movement, and this kind of movement also completely avoids the occurrence of wheel theft. The distance range of the vehicle's forward and backward movement is preset in advance to prevent the vehicle from moving too far when there are no obstacles. Set the maximum forward distance and the maximum backward distance of the vehicle, and then control the vehicle's forward and backward movement according to the maximum forward and backward distances. At the same time, detect obstacles in the forward and backward directions through the radar and adjust the final movement distance based on the obstacles.

[0044] If the vehicle tilts, locate the wheels at risk of theft by collecting the tilt direction and / or wheel height information, and control the rotation of the located wheels at risk of theft. When the vehicle tilts, it means that the vehicle has been jacked up by the jack at this time, and there is already a risk of tire removal. At this time, the tilt direction or wheel height collected can be used to determine and locate which wheel or which wheels are jacked up. Then control the rotation of the stolen wheels to prevent the theft. For example, the height of the jacked-up wheel changes, and the vehicle tilt angle and direction collected by a gyroscope, tilt angle sensor, etc. can also be used to determine the specific tilt position and the position of the wheels at risk of theft. Then control the rotation of these wheels at risk of theft to interfere with the removal of the tires, because the rotation of the wheels will cause the fixing screws of the tires to be unable to be removed. Therefore, anti-theft can be achieved by controlling the rotation of the wheels.

[0045] In this embodiment, for a wheel at risk of theft, controlling its rotation can achieve anti-theft, and its rotation speed also needs to be regulated. The rotation speed of the wheel at risk of theft is less than the set threshold, and the rotation of the wheel is controlled in a variable speed and variable direction manner. The rotation speed of the wheel cannot be too fast, as it will pose a safety hazard; therefore, it is necessary to limit the rotation speed of the wheel, and limit the magnitude of the rotation speed of the wheel to the maximum set threshold, so that the speed does not exceed the threshold. Although the speed is small, in order to interfere with the disassembly of the wheel, the rotation speed of the wheel cannot be kept constant. Therefore, in this application, the rotation speed of the wheel is controlled to be variable speed and variable direction. Variable speed means that the rotation speed is real-time changing and not fixed during the rotation of the wheel. Variable direction means that the rotation direction of the wheel changes periodically, and it can rotate forward or backward. By periodically changing the rotation direction and the change of the rotation speed, the disassembly of the wheel can be reduced or avoided.

[0046] This embodiment also provides a wheel anti-theft control system, including an anti-theft system switch and a domain controller; after the vehicle is powered off, a first instruction is sent to the domain controller through the anti-theft system switch to control the start of the wheel anti-theft monitoring process. After the wheel anti-theft monitoring process starts, the domain controller monitors and judges the theft risk of the current vehicle and generates a second instruction, and issues an anti-theft alarm signal by executing the second instruction.

[0047] In this embodiment, the control system further includes an in-vehicle TBOX, a cloud platform, and a mobile phone APP. The second instruction generated by the domain controller is sent to the mobile phone APP through the in-vehicle TBOX and the cloud platform to enable the mobile phone APP to issue an anti-theft alarm. The domain controller generates the second instruction according to the theft risk. When there is a theft risk, the domain controller generates the second instruction, and the second instruction is executed by the in-vehicle alarm and the mobile phone vehicle networking APP respectively. The second instruction is sent to the in-vehicle voice system through the vehicle CAN network, and the in-vehicle voice system executes the second instruction and issues a corresponding theft risk reminder, and drives away the theft personnel by means of voice alarm, so as to achieve the purpose of theft reminder and driving away the theft personnel. At the same time, the second instruction is transmitted to the cloud platform TSP through the in-vehicle TBOX, and the cloud platform TSP sends the second instruction to the user's mobile phone APP. After receiving the second instruction, the mobile phone APP executes the second instruction and displays information such as text, voice, and images of the wheel theft risk reminder through the mobile phone APP to convey the current wheel theft risk to the user and remind the user to pay attention to handling.

[0048] The domain controller can be one or more. Taking two domain controllers as an example, the LZCU domain controller is used to monitor the theft risk of the two left tires, and the RZCU is used to monitor the theft risk of the two right tires. Both domain controllers are connected to the in-vehicle alarm and are connected to the cloud platform through the TBOX, so as to achieve local and remote alarms.

[0049] A control method for a wheel anti-theft system provided in this embodiment mainly realizes the functions of the wheel anti-theft system by adding a remote control function and installing an anti-theft monitoring sensor on the wheel. A wheel anti-theft system includes a platform, a TBOX, an LZCU, and an RZCU.

[0050] The platform module is used for the user to turn on the soft switch of the wheel anti-theft system. In the case of abnormal wheels, it sends text reminders to the user, such as "The wheel is abnormal, please check it in time" and "There is a risk of wheel theft".

[0051] The TBOX module is used to feedback the actual state and functional state of the wheel to the platform, send network wake-up requests and wheel anti-theft function requests to the left domain / right domain controller and perform encryption authentication.

[0052] The LZCU module is used to monitor the tire pressure of the left vehicle wheel and feedback the actual state of the wheel to the TBOX module, so as to realize the user's real-time monitoring of the state of the left wheel.

[0053] The RZCU module is used to monitor the tire pressure of the right vehicle wheel and feedback the actual state of the wheel to the TBOX module, so as to realize the user's real-time monitoring of the state of the right wheel.

[0054] As Figure 1 shown, it is described with reference to the operation flowchart of the remote wheel anti-theft system: When the vehicle is powered off, the user needs to turn on the wheel anti-theft system switch with one key in the App. The TSP will send a remote control instruction. After receiving the instruction, the TBOX sends the signal to the domain controller. The domain controller monitors the actual state of the wheel in real time. In case of special situations, such as the wheel is loose / someone approaches the wheel / abnormal tire pressure, the vehicle will give a voice prompt and display the actual state of the wheel in the APP, and a text prompt "There is a risk of wheel theft" will be shown.

[0055] As Figure 2 shown, it is described with reference to the block diagram of the remote wheel anti-theft function system: The platform sends a request to turn on the wheel anti-theft function. The TBOX receives the request and feedbacks the functional state and the actual state of the wheel. The TBOX sends a network wake-up request, encryption authentication, and a request to turn on the wheel anti-theft function to the left domain / right domain. Then the left domain / right domain will feedback the encryption authentication and the actual state of the wheel. The user's mobile phone App has a soft button for this function, which can display the state of the vehicle wheels in real time. Abnormal states such as abnormal tire pressure and loose wheels are allowed. The App will send a reminder to the user "The wheel is abnormal, please check it in time".

[0056] The control method of the automotive wheel anti-theft system in this solution mainly adds a remote control function. While the vehicle gives a voice prompt, the mobile phone App will also have a text prompt. This implementation method of dual reminders reduces the risk of wheel theft. At the same time, the interference of wheel theft is realized through the wheel control strategy, further enhancing safety.

[0057] Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
