[0003] Currently, car rental companies typically use the following methods to manage their vehicles:
[0004] 1. GPS tracking technology can locate a vehicle by installing a GPS device on it. However, this method can only provide location information and cannot restrict the vehicle's usage rights of drivers who break their promises. Therefore, it is difficult to fundamentally solve the problem of drivers using vehicles in violation of their promises.
[0005] 2. Manual collection and vehicle recovery: Car rental companies need to collect rent by phone or other means, or arrange personnel to find and recover defaulted vehicles. This method is not only inefficient, but also costly, requiring a large investment in manpower and time.
[0006] 3. Physical key handover: In the short-term rental model, users must go to the rental location to pick up and return the keys. The process is cumbersome, which affects the user's rental experience and also brings high key management difficulty and cost to the rental company. Summary of the Invention

[0039] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numbers in the drawings represent functionally the same or similar elements. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
[0040] The word "exemplary" is used herein in the sense of being an example, instance, or illustration. Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.
[0041] In addition, in order to better illustrate the present application, numerous specific details are given in the specific embodiments below. Those skilled in the art should understand that the present application can also be implemented without certain specific details. In some examples, methods, means, elements well known to those skilled in the art are not described in detail, in order to highlight the main idea of the present application.
[0042] Embodiment 1;
[0043] The present application provides an intelligent Bluetooth key and vehicle management system, a key box module: a built-in safety box for fixing the original car key and connecting with the vehicle circuit through a wire harness, the safety box is hiddenly installed in the vehicle, and is prevented from being physically damaged by a anti-disassembly structure.
[0044] The key box module is built-in a safety box, which is hidden and installed in a position not easy to be found in the vehicle, such as the inside of the instrument panel or under the seat, etc. The safety box adopts a tamper-proof structure design, for example, through screws or buckles. If it is violently disassembled, the internal sensor will immediately trigger the alarm mechanism. At the same time, the safety box is connected with the vehicle circuit through a wire harness. The interface of the wire harness matches the original key circuit interface of the vehicle, which can simulate the circuit signal of the original vehicle key. Under normal permission, the key box module controls the vehicle door lock through the key circuit board. When the user's permission is revoked, the internal electronic switch will automatically disconnect the signal transmission, so that the vehicle cannot be started.
[0045] Communication module: integrated Bluetooth unit and 4G unit, used for real-time communication with user mobile terminal and management background.
[0046] The communication module integrates Bluetooth unit and 4G unit. The Bluetooth unit adopts low-power Bluetooth technology, which supports near-distance and fast connection with user mobile terminal. In short-term rental mode, the user can establish Bluetooth communication with the vehicle within a certain range (such as 10 meters) near the vehicle through the mobile phone APP, and realize unlocking and starting operation. The 4G unit is used for real-time communication with the management background. When the Bluetooth connection is not available, such as when the user is far away from the vehicle or the Bluetooth signal is disturbed, the 4G unit can receive key information such as forced locking instructions from the management background through the cellular network, ensuring that the management background's control over the vehicle is not limited by distance and environment.
[0047] Permission management module: dynamically control user permissions according to rental status, including real-time adjustment of user's vehicle starting permission based on rental payment status in long-term rental mode, and limiting user to unlock the vehicle through Bluetooth connection within the scheduled time period in long-term rental mode.
[0048] User identity verification unit: before using the car rental service, the user needs to complete registration and identity verification on the mobile phone APP. During the identity verification process, the APP collects the user's basic features such as face information or fingerprint information through the mobile phone camera. At the same time, it also supports dynamic verification code verification method. After the user submits the verification information, the APP will encrypt the data and transmit it to the management background for comparison and verification. Only after the verification is passed, the Bluetooth module will verify the user's permission and send the unlocking instruction to the vehicle control module.
[0049] Time policy unit: in short-term rental mode, when the user books a vehicle through the APP, the user needs to set the use time period, and the system sets the vehicle use time window according to the time period. Before approaching the end of the scheduled time window, the system automatically sends a renewal reminder to the user's mobile terminal through Bluetooth. If the user does not apply for renewal, after the time window ends, the system starts the idling and allows the user to use the vehicle in a limited mode within fifteen minutes after the overtime, such as limiting the driving range to within 5 kilometers of the current location. If the user still does not renew the fee after fifteen minutes, the permission management module sends a complete locking instruction to the vehicle control module through the communication module.
[0050] Vehicle control module: receiving management background instructions, executing vehicle locking, unlocking or starting operation.
[0051] The vehicle control module, as a system execution unit, receives instructions sent by the management background through the communication module in real time. When an unlocking instruction is received, the vehicle control module analyzes the instruction and controls the door unlocking and the control module starting through the internal circuit. When a locking instruction is received, the vehicle locking operation is immediately executed, including closing the door, cutting off the control module power supply, etc. In the initial overdue stage, the vehicle control module analyzes the limit speed instruction sent by the management background, generates an analog vehicle speed signal by covering the original vehicle speed sensor data through the vehicle preset threshold, and when the actual vehicle speed exceeds the preset threshold (such as 30 kilometers / hour), the control module sends a power reduction instruction to the engine electronic controller through the vehicle self-diagnosis interface, realizing the limitation of the maximum speed of the vehicle.
[0052] Safety alarm module: when the user's permission is revoked, triggering the vehicle sound and light alarm and sending the GPS coordinate positioning data to the management background.
[0053] Permission revocation alarm mechanism: when the user's permission is revoked, such as not paying the rent on time or exceeding the lease period, the safety alarm module immediately triggers the vehicle sound and light alarm, and sends the GPS coordinate positioning data to the management background. In addition, after the alarm is triggered, the safety alarm module synchronously activates the vehicle self-diagnosis interface, limits the power output, prevents the user from continuing to use the vehicle in violation of the rules, and continuously uploads the GPS position to the management background, so as to facilitate the rental company to grasp the vehicle position information in real time.
[0054] Stage permission revocation operation, initial overdue stage: when the user first overpays the rent or exceeds the lease period, the management background sends an instruction to the vehicle control module through the 4G unit. The vehicle control module limits the maximum speed of the vehicle to a preset threshold (such as 30 kilometers / hour) according to the instruction, and at the same time, the management background pushes the overdue warning and grace period notice to the user through the mobile phone APP, reminding the user to handle the overdue problem as soon as possible.
[0055] Secondary overdue stage: if the user does not handle the overdue problem within the grace period, the management background sends instructions to the vehicle control module through the 4G unit again, completely locks the vehicle control module, triggers the sound and light alarm, and limits the power output to the idle state through the vehicle self-diagnosis interface. At this time, the vehicle cannot run normally and can only maintain basic idle operation.
[0056] Forced recovery stage: after the vehicle is locked, the management background tracks the vehicle location through GPS. If the vehicle is not recovered within the set time, the management background sends positioning data and electronic authorization key to the third-party towing service to start the automatic towing process, ensuring that the vehicle can be smoothly recovered and reducing the asset loss of the rental company.
[0057] Embodiment 2;
[0058] In the long-term rental mode, after the user completes registration and identity verification, a lease contract is signed with the rental company, and the management background opens the corresponding vehicle start permission for the user according to the contract information. This process is completed through the cooperation of the permission management module and the communication module, realizing fast and safe permission opening. During the lease period, the permission management module uses advanced data monitoring technology to obtain the user's rent payment status in real time. If the user pays the rent on time, the vehicle control module can quickly and stably respond to the unlock and start instructions, ensuring normal use of the vehicle by the user. The simple and fast operation process improves the user's experience. Once there is an overdue payment, the security alarm module starts the phased permission revocation operation. In the initial overdue stage, the vehicle control module limits the vehicle's maximum speed to a preset threshold (such as 30 km / h) through the vehicle's preset threshold. At the same time, the management background pushes overdue warnings and grace period notifications to the user through the mobile phone APP. This restriction measure not only safeguards the interests of the rental company but also gives the user enough advance time. If the user still does not handle it within the grace period, the secondary overdue stage will completely lock the vehicle control module, trigger the sound and light alarm, and limit the power output to the idle state, effectively preventing the user from continuing to use the vehicle in violation of the rules. In the forced recovery stage, the management background tracks the vehicle location through GPS. If the vehicle is not recovered within the set time, it sends positioning data and electronic authorization key to the third-party towing service to start the automatic towing process, greatly reducing the cost and difficulty of manual collection and vehicle recovery for the rental company, and significantly improving management efficiency.
[0059] In the short-term rental mode, the traditional physical key handover process is cumbersome, seriously affecting the user experience and increasing the enterprise management cost. The user only needs to select a vehicle and reserve a time period through a mobile phone APP, and after completing the payment, arrives near the vehicle within the reserved time period, and establishes a Bluetooth connection with the vehicle through the mobile phone APP. In this process, the user identity authentication unit of the permission management module completes authentication through APP collection of biometric features or dynamic verification code, ensuring that only legitimate users can obtain permission, thereby ensuring the safety of vehicle use. After authentication, the vehicle control module quickly performs unlocking and starting operations. The entire process does not require cumbersome key handover, simplifies the rental process, and improves the user experience. During use, the time strategy unit monitors the use time in real time, and one hour before the end of the time window, the system automatically sends a renewal reminder to the user's mobile terminal through Bluetooth. If the user does not apply for renewal, the system starts idling after the timeout, and allows the user to temporarily use the vehicle in a limited mode (such as limiting the driving range to within 5 kilometers of the current location) within fifteen minutes, giving the user some flexibility. If the user still does not renew the fee after fifteen minutes, the system performs complete locking, effectively preventing the user from occupying the vehicle beyond the timeout, thereby protecting the interests of the rental company and the normal development of subsequent business.
[0060] Through the long-term and short-term rental modes, the intelligent Bluetooth key and vehicle management system solves the vehicle asset management safety problem of the rental industry from multiple aspects. In terms of management efficiency, it reduces a large amount of tedious work such as manual collection and key management. Through automatic permission management and vehicle control, efficient vehicle management is achieved. In terms of user experience, the rental process is simplified, convenient and efficient services are provided, and the use of users is safer and more intelligent through safe and reliable identity authentication and permission management.
