Abstract
Description
Technical Field
[0001] This invention relates to the field of two-wheeled vehicle technology, and more particularly to a UWB keyless proximity start / stop and anti-tampering locking method for two-wheeled vehicles. Background Technology
[0002] Two-wheeled vehicles include electric vehicles and electric-assisted vehicles, which use electricity to help users reach their destinations more quickly.
[0003] Traditional two-wheeled vehicles use mechanical keys to start, unlock, and turn off, but mechanical methods are easily stolen and inconvenient to use.
[0004] Existing two-wheeled vehicles use wireless keyless entry for unlocking and starting, which provides better anti-theft protection than mechanical keyless entry. However, manual pressing of the wireless key is required to unlock the vehicle. Over time, the buttons on the wireless key are easily damaged due to their exposed nature. Once the buttons on the wireless key are damaged, the two-wheeled vehicle will not be able to start and will have to be pushed to move.
[0005] Secondly, when the user is not present, the drive wheels and auxiliary wheels are in a released state, and one of the tires is usually locked using an external mechanical lock. However, this locking state is based on the locked state of the external mechanical lock, and in principle, it is impossible to completely lock the tire. The tire can still rotate within a certain range of motion. If the two-wheeled vehicle is moved within the range of the tire's movement during the relocation process, the two-wheeled vehicle can still be stolen.
[0006] Meanwhile, the use of mechanical locks to lock the two-wheeled vehicle through its tires makes it vulnerable to theft if the lock is broken by external force. Summary of the Invention
[0007] Based on this, it is necessary to propose a UWB keyless proximity start / stop and anti-tampering locking method for two-wheeled vehicles to address the above problems.
[0008] A UWB keyless proximity start-stop and anti-tampering locking method for two-wheeled vehicles, comprising: Detect whether a UWB signal corresponding to the UWB key bound to the two-wheeled vehicle is detected within a preset receiving range; If it does not exist, a locking command is generated and executed to put the tire in a locked state, thereby locking the tire. In at least one embodiment of this application, the UWB keyless proximity start / stop and anti-tampering locking method applied to two-wheeled vehicles further includes: If it exists, an unlocking command is generated, the unlocking command is executed, the two-wheeled vehicle is started, and the lock control command is released.
[0009] In at least one embodiment of this application, during the execution of the locking command, it is detected whether the two-wheeled vehicle has a center of gravity shift. If the center of gravity shifts, the position coordinates of the two-wheeled vehicle at the time of initial locking are obtained to generate the original position, and the position coordinates of the two-wheeled vehicle at the time of center of gravity shift are obtained to generate the moving position. Based on the original position and the moved position, an anti-theft control command is generated to control the drive wheel to move in the opposite direction.
[0010] In at least one embodiment of this application, the specific steps of generating an anti-theft control command based on the original position and the moved position to control the reverse movement of the drive wheel include: Calculate the position offset vector based on the original position and the moved position; The position offset vector is parsed to generate a movement direction. Reverse movement data is generated based on the movement direction, and the anti-theft control command is generated based on the reverse movement data.
[0011] In at least one embodiment of this application, the specific step of calculating the position offset vector based on the original position and the moved position further includes: The position offset vector is parsed to generate an offset distance. The offset distance is compared with a threshold upper limit. If it is greater than the threshold upper limit, the anti-theft control command is generated.
[0012] In at least one embodiment of this application, the UWB keyless proximity start / stop and anti-tampering locking method applied to two-wheeled vehicles further includes: If the offset distance is not greater than the upper limit of the threshold, the offset distance is accumulated as a cumulative offset; when the cumulative offset is greater than the upper limit of the threshold, the anti-theft control command is generated.
[0013] In at least one embodiment of this application, the UWB keyless proximity start / stop and anti-tampering locking method applied to two-wheeled vehicles further includes: After executing the anti-theft control command, check whether the two-wheeled vehicle is off the ground; If the vehicle is off the ground, the unique identifiers of at least two adjacent components in the preset component set are bound together. If a corresponding UWB signal for the two-wheeled vehicle exists, the original activation code stored inside the UWB key of the two-wheeled vehicle is verified. If the original activation code fails, a locking control command is generated to control the preset component set to enter the locked state and cut off the power.
[0014] In at least one embodiment of this application, the UWB keyless proximity start / stop and anti-tampering locking method applied to two-wheeled vehicles further includes: If there is no corresponding UWB signal for the two-wheeled vehicle UWB key, a locking control command is generated to control the preset component set to enter the locked state and cut off the power.
[0015] In at least one embodiment of this application, the specific steps for detecting whether the two-wheeled vehicle is off the ground after executing the anti-theft control command include: Obtain the tire pressure when the locking command is executed, and generate the initial tire pressure; After executing the anti-theft control command, the tire pressure of the two-wheeled vehicle during the detection process is obtained, and a tire pressure to be checked is generated; The tire pressure to be checked is compared with the initial tire pressure. If the tire pressure to be checked is less than the initial tire pressure, it is determined that the tire is off the ground.
[0016] In at least one embodiment of this application, the UWB keyless proximity start / stop and anti-tampering locking method applied to two-wheeled vehicles further includes: The tire pressure to be checked is compared with the initial tire pressure. If the tire pressure to be checked is not less than the initial tire pressure, it is determined that the tire has not left the ground.
[0017] Implementing the UWB keyless proximity start / stop and anti-tampering locking method for two-wheeled vehicles according to this embodiment will have at least the following beneficial effects: 1. The above-mentioned UWB keyless proximity start-stop and anti-tampering locking method for two-wheeled vehicles determines that the owner has left, the key is not near the vehicle, or unauthorized approach is made if no UWB signal of the UWB key bound to the vehicle is detected within the detection period.
[0018] At this time, the controller automatically generates a locking command and sends it to the vehicle-mounted locking actuator. The locking actuator can be an existing electrically controllable wheel lock structure such as a motor-operated brake type, an electronically controlled brake caliper type, or a wheel axial locking type. After receiving the locking command, it directly drives the vehicle's wheels into a locked state, so that the tires cannot rotate freely under external force, thereby enabling the vehicle to automatically enter the anti-moving protection state after the owner leaves.
[0019] Wireless unlocking via the UWB signal corresponding to the UWB key avoids the problem of traditional button keys causing damage and preventing the vehicle from starting.
[0020] Secondly, the locking action is automatically initiated by the vehicle controller when it cannot detect the bound UWB signal, which significantly improves the anti-theft performance in parking scenarios.
[0021] Locking is an electronically controlled locking mechanism applied to the wheels, which can achieve a higher restraint force than external mechanical locks. It avoids the situation where existing mechanical locks can only restrict the wheels within a certain range of motion and can still be moved little by little. It is also not easy to completely fail after being simply cut, thereby improving the vehicle's resistance to being moved and its anti-theft capabilities.
[0022] 2. In the UWB keyless proximity start / stop and anti-tampering locking method for two-wheeled vehicles provided above, when the controller analyzes this position offset vector, it first extracts the direction component of the vector to generate the movement direction. For example, it determines whether the vehicle is being dragged forward, backward, or laterally, or moving diagonally forward or backward. After determining the movement direction, the controller then constructs a set or segment of reverse running data in the opposite direction to that movement direction.
[0023] The reverse output is generated according to the direction of movement. This allows the thief to encounter a reverse force when pushing the car forward, as if the car itself is pushing back. The more obvious the push, the greater the offset, and the clearer the vector, the more targeted the reverse operation data generated by the controller will be, thus improving the anti-theft performance.
[0024] Meanwhile, the step-by-step logic of first calculating the position offset vector and then generating the reverse running data facilitates subsequent use with strategies such as offset thresholds and cumulative offsets, reduces false triggers caused by slight shaking or environmental interference, and improves the accuracy of anti-moving and anti-theft measures.

Detailed Implementation
[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] A UWB keyless proximity start-stop and anti-tampering locking method for two-wheeled vehicles, comprising: S100: Detect whether a UWB signal corresponding to the UWB key bound to the two-wheeled vehicle is detected within a preset reception range.
[0029] S101. If it does not exist, generate a locking command and execute the locking command to put the tire in a locked state so that the tire is locked.
[0030] This method is applied to two-wheeled vehicles such as electric vehicles and electric-assisted bicycles. The vehicle is equipped with a UWB receiver module corresponding to the UWB key bound to the vehicle and an on-board controller electrically connected to it. When the vehicle is in standby or powered on, the on-board controller periodically listens to the UWB signal in the surrounding space and sets a preset reception range based on the vehicle itself, such as a near-field area of 1m to 2.5m around the vehicle body, which is used to indicate the range of activities that the owner or legitimate user can normally approach, park, and get off the vehicle.
[0031] When the controller detects a UWB signal emitted by the bound UWB key within the preset reception range, it determines that the current unlocking method is legitimate and can maintain the vehicle's normal standby or unlocked state.
[0032] Please refer to Figures 1-3 In this embodiment, if no UWB signal of the UWB key bound to the vehicle is detected within the detection period, it is determined that the vehicle owner has left, the key is not near the vehicle, or unauthorized personnel have approached.
[0033] At this time, the controller automatically generates a locking command and sends it to the vehicle-mounted locking actuator. The locking actuator can be an existing electrically controllable wheel lock structure such as a motor-operated brake type, an electronically controlled brake caliper type, or a wheel axial locking type. After receiving the locking command, it directly drives the vehicle's wheels into a locked state, so that the tires cannot rotate freely under external force, thereby enabling the vehicle to automatically enter the anti-moving protection state after the owner leaves.
[0034] Wireless unlocking via the UWB signal corresponding to the UWB key avoids the problem of traditional button keys causing damage and preventing the vehicle from starting.
[0035] Secondly, the locking action is automatically initiated by the vehicle controller when it cannot detect the bound UWB signal, which significantly improves the anti-theft performance in parking scenarios.
[0036] Locking is an electronically controlled locking mechanism applied to the wheels, which can achieve a higher restraint force than external mechanical locks. It avoids the situation where existing mechanical locks can only restrict the wheels within a certain range of motion and can still be moved little by little. It is also not easy to completely fail after being simply cut, thereby improving the vehicle's resistance to being moved and its anti-theft capabilities.
[0037] In at least one embodiment of this application, the UWB keyless proximity start / stop and anti-tampering locking method applied to two-wheeled vehicles further includes: S102. If it exists, generate an unlock command, execute the unlock command, control the two-wheeled vehicle to start and release the lock control command.
[0038] Please refer to Figures 1-3 In this embodiment, the vehicle controller periodically detects the preset UWB reception range. When the UWB signal of the UWB key bound to the vehicle reappears within the preset range and remains valid for several consecutive detection cycles, the controller determines that a legitimate user is approaching the vehicle with the key. Subsequently, the controller generates an unlocking command and sends it to the vehicle's locking actuator and vehicle control unit.
[0039] Upon receiving the unlocking command, the locking actuator disengages from its original holding, locking, or brake holding state, restoring the locked wheel to a rotatable state.
[0040] After receiving the unlock command, the vehicle control unit opens the vehicle's starter circuit or allows the drive power supply to be powered on, enabling the vehicle to enter a startable and drivable working state, thereby realizing a reciprocating closed-loop control that automatically locks when the key is removed and automatically unlocks and starts when the key is returned.
[0041] The unlocking action corresponds one-to-one with the logic of locking upon leaving, enabling the vehicle to automatically switch between anti-theft, anti-moving, and normal riding conditions. This ensures the vehicle remains safe when unattended and quickly returns to a rideable state when someone is present and the key is valid, thereby improving its applicability and anti-theft capabilities.
[0042] In at least one embodiment of this application, S201, during the execution of the locking command, it is detected whether the two-wheeled vehicle has a center of gravity shift. If the center of gravity shifts, the position coordinates of the two-wheeled vehicle at the initial locking are obtained to generate the original position, and the position coordinates of the two-wheeled vehicle at the center of gravity shift are obtained to generate the moving position.
[0043] Based on the original position and the moved position, an anti-theft control command is generated to control the drive wheel to move in the opposite direction.
[0044] Please refer to Figures 1-3 In this embodiment, once the vehicle enters the locking state, the system continuously monitors whether the two-wheeled vehicle experiences a center of gravity shift throughout the entire period of executing the locking command. (The detection of center of gravity shift can be achieved using attitude sensors, accelerometers, gyroscopes, six-axis / nine-axis IMUs, or even tilt sensors fixed to the frame, all mounted on the vehicle body.) The controller records the attitude parameters and position data of the vehicle when it executes the locking command and when the vehicle is in a normal parking posture. The vehicle position coordinates at that moment are used as the initial locking position and the original position is generated.
[0045] When a vehicle is dragged, pushed sideways, lifted from the rear, or moved slowly on the ground, its posture, tilt angle, and acceleration will change significantly from when it is stationary. Based on this, the controller determines that the vehicle's center of gravity has shifted.
[0046] Once a center of gravity shift is detected, the controller immediately reads the vehicle's position coordinates at this time (which can be parking space coordinates, relative ground coordinates, relative displacement coordinates calculated by inertial navigation, or coordinates obtained in conjunction with the ranging and positioning unit installed on the vehicle body), and generates the moving position from these coordinates.
[0047] Then, based on the original position and the moved position, the controller can determine whether the vehicle has been moved while it is locked.
[0048] Based on this judgment, the controller generates an anti-theft control command according to the offset relationship between the original position and the moving position. The content of the anti-theft control command may include: controlling the drive wheel to move in the opposite direction to the direction of movement for a short time or outputting a reverse drive torque, thereby making the drive wheel generate a restraining force or braking force opposite to the direction of movement, forming an active resistance to the external force of moving the vehicle, rather than the static state of a traditional mechanical lock.
[0049] During the locking period, the center of gravity continues to be monitored. Once the vehicle is pushed, lifted, or moved laterally, the changes in the original position and the moving position are immediately obtained and a reverse drive command is issued to prevent the vehicle from being moved.
[0050] Traditional electronic locking systems simply increase tire resistance or lock the vehicle. Once the ground slips, the vehicle is lifted, or it is carried away by two people, the locking resistance decreases. However, this embodiment outputs a reverse force / disturbance force through the reverse motion of the drive wheels, which can give the mover a reverse force / disturbance force the moment the vehicle is moved, increasing the difficulty of moving it.
[0051] Reverse motion is based on the objective quantitative offset between the original position and the moved position, which can reduce false alarms caused by wind, slight touch, or roadside shaking, and improve theft prevention.
[0052] In at least one embodiment of this application, the specific steps of generating an anti-theft control command based on the original position and the moved position to control the reverse movement of the drive wheel include: S202. Calculate the position offset vector based on the original position and the moved position.
[0053] S204. Parse the position offset vector to generate a movement direction, generate reverse running data based on the movement direction, and generate the anti-theft control command based on the reverse running data.
[0054] Please refer to Figures 1-3 In this embodiment, after the vehicle is in the locked state and the vehicle's center of gravity shift has been detected, and the original position at the initial locking and the moving position when the shift occurred have been obtained, the controller calculates the difference between the original position and the moving position to obtain a position offset vector.
[0055] The original position and the moved position can be represented in the same coordinate system (e.g., a Cartesian coordinate system with the vehicle's parking point as the origin, or a vehicle coordinate system with the vehicle's longitudinal direction as X and the lateral direction as Y). Then, the original position is subtracted from the moved position to obtain a vector pointing from the original position to the moved position. This vector contains both the direction information of the vehicle's movement and the amount of displacement information.
[0056] When the controller analyzes this position offset vector, it first extracts the direction component of the vector to generate the movement direction. For example, it determines whether the object is being dragged forward, backward, or laterally, or moving diagonally forward or backward. After determining the movement direction, the controller then constructs a set or segment of reverse movement data in the opposite direction to that movement direction.
[0057] The reverse operation data can include parameters such as the reverse rotation direction of the drive wheel, the reverse speed, the reverse operation duration, and the magnitude of the reverse torque or braking force to be output. Finally, based on these parameters, an anti-theft control command is generated and sent to the drive motor controller or wheel locking actuator corresponding to the drive wheel, so that the drive wheel moves in the opposite direction to the direction being moved for a short time or applies reverse braking force, thereby targeting, pulling back, or disturbing the behavior of moving the vehicle by external force.
[0058] This embodiment does not simply increase resistance to the wheels, but rather outputs the reverse direction of movement. This allows the thief to encounter a reverse force when pushing the car forward, as if the car itself is pushing back. The more obvious the push, the greater the offset, and the clearer the vector, the more targeted the reverse operation data generated by the controller becomes, thus improving the anti-theft capability.
[0059] Meanwhile, the step-by-step logic of first calculating the position offset vector and then generating the reverse running data facilitates subsequent use with strategies such as offset thresholds and cumulative offsets, reduces false triggers caused by slight shaking or environmental interference, and improves the accuracy of anti-moving and anti-theft measures.
[0060] In at least one embodiment of this application, the specific step of calculating the position offset vector based on the original position and the moved position further includes: S203. Parse the position offset vector to generate an offset distance, compare the offset distance with a threshold upper limit, and if it is greater than the threshold upper limit, generate the anti-theft control command.
[0061] Please refer to Figures 1-3 In this embodiment, the controller parses the position offset vector, extracts the magnitude of the vector, and uses it as the offset distance at which the vehicle is moved.
[0062] Then, the controller presets a threshold upper limit (manually preset) in the system parameters. This threshold upper limit can be configured according to the vehicle's weight, common parking vibration, and sensor accuracy. For example, it can be set to a few centimeters or tens of centimeters to indicate the upper limit of the threshold to determine whether the vehicle can be moved.
[0063] The controller compares the calculated offset distance with the upper limit of the threshold: if the offset distance is greater than the upper limit of the threshold, it means that the vehicle has undergone substantial displacement beyond the normal shaking range while under lock control. The controller then generates and issues an anti-theft control command, causing the drive wheels to perform reverse movement, reverse torque output, or enter a higher level of protection. If the offset distance does not exceed the upper limit of the threshold, it can be considered as a small displacement caused by wind, minor collision, the user moving the car to right it, or uneven ground. In this case, the controller does not immediately enter strong protection to avoid unnecessary alarms or reverse towing.
[0064] This solution establishes anti-theft actions based on actual moving exceeding the threshold, rather than on any minute displacement, by comparing position offset vectors, offset distances, and thresholds, and triggering a link only when the value exceeds the threshold. This retains the active anti-moving capability of detecting being dragged and pushing back, while using a simple and adjustable threshold to filter out minor daily disturbances, achieving a balance between anti-theft accuracy and ease of use.
[0065] In at least one embodiment of this application, the UWB keyless proximity start / stop and anti-tampering locking method applied to two-wheeled vehicles further includes: S205. If the offset distance is not greater than the upper limit of the threshold, the offset distance is accumulated as a cumulative offset; when the cumulative offset is greater than the upper limit of the threshold, the anti-theft control command is generated.
[0066] Please refer to Figures 1-3 In this embodiment, if the offset distance is not greater than the preset threshold limit during a locking cycle (i.e., during the parking locking period after unlocking), the controller does not directly trigger the anti-theft action. Instead, it treats the small offset as a suspicious but not enough displacement and adds the offset distance to the cumulative offset maintained during the locking cycle.
[0067] Subsequently, in subsequent monitoring cycles, as long as the vehicle remains locked and there are still offset distances less than the threshold, the controller continues to add these small displacements to the cumulative offset. When the value of this cumulative offset eventually exceeds the same upper limit of the threshold, it means that although each movement is small, the total displacement has reached the level of actual removal. At this time, the controller immediately generates an anti-theft control command and sends it to the drive wheels or locking actuator to perform reverse movement, forced braking, or enter the next level of protection.
[0068] During theft, thieves may use multiple small pushes or segmented movements to circumvent anti-theft measures triggered by a single large displacement.
[0069] If the system detects a single offset, the theft will occur through slow, piecemeal movement, eventually being carried away little by little. By accumulating each small offset that is below the threshold, and only triggering anti-theft measures when the total exceeds the threshold, this method of theft involving multiple small pushes and piecemeal movement can be identified.
[0070] At the same time, it will not immediately reverse drive due to slight ground vibrations, wind, or minor displacement caused by a neighboring vehicle, thus ensuring stability and user experience in daily parking scenarios.
[0071] This makes the anti-moving logic both sensitive and insensitive, capable of detecting multiple small pushes and segmented moves while shielding against occasional disturbances, thus making the entire UWB keyless anti-theft method more practical and more resistant to bypassing.
[0072] In at least one embodiment of this application, the UWB keyless proximity start / stop and anti-tampering locking method applied to two-wheeled vehicles further includes: After executing the anti-theft control command, it checks whether the two-wheeled vehicle is off the ground.
[0073] S304. If the vehicle is off the ground, bind the unique identifiers of at least two adjacent components in the preset component set. If a corresponding UWB signal for the two-wheeled vehicle exists, verify the original activation code stored inside the UWB key of the two-wheeled vehicle. If the original activation code fails, generate a locking control command to control the preset component set to enter the locking state and cut off the power.
[0074] Please refer to Figures 1-3 In this embodiment, after the vehicle is detected to be dragged / moved while under lock and the anti-theft control command has been executed, the vehicle controller will further enter the removal judgment process to identify whether the thief is bypassing the wheel lock and directly lifting the vehicle to leave.
[0075] Anti-movement operation is mainly aimed at scenarios of pushing or dragging on the ground. If the front and rear wheels of the car are lifted off the ground, the actions of tire locking and reverse drive will be greatly reduced.
[0076] In this embodiment, after executing the anti-theft control command, the controller will immediately collect parameters for determining the off-ground status, such as comparing the tire pressure value when the lock is executed with the current tire pressure value, detecting whether the shock absorption stroke is in a fully extended state, and detecting whether the vehicle attitude sensor / IMU is in a suspended state. Once it is determined that the vehicle is off the ground, it is considered that the current moving behavior has been upgraded from ordinary trolley pushing to forced removal / lifting, entering a higher level of protection mode.
[0077] After entering this advanced protection mode, the controller will select at least two adjacent or functionally coupled key components from the preset set of components in the vehicle (such as the drive motor controller and battery management unit, the power control module and instrument panel on the frame side, the electronic central control and positioning module, etc.), read their respective unique identifiers (UIDs), and bind the unique identifiers of these two (or more) adjacent components at once under the current ground departure event, forming a set of currently legal component binding relationships for this vehicle.
[0078] Next, the controller will check if there is a UWB signal from the UWB key bound to the vehicle nearby. If there is, it will further request the UWB key to send back or participate in the authentication of its internally stored original activation code to prove that although the car has been lifted, it is indeed the owner who is moving the car.
[0079] If the original activation code fails verification, it indicates that the current off-ground movement is not a legitimate user operation. The controller immediately generates a locking control command, pulling the aforementioned pre-bound components into a locked state. At the same time, it cuts off or disables the associated power supply and drive paths. This ensures that even if the thief has lifted the vehicle off the ground or even removed some components, these core components cannot be made to work again without the correct activation code. This completes the entire anti-theft process of lifting, identifying, binding, verifying the key, locking and cutting off power if the operation is illegitimate.
[0080] By making the unique identifier of the preset set of components a dynamic binding in the off-ground scenario, it is equivalent to putting an electronic lock on these key components that is "only valid for this vehicle and this removal action". Even if thieves disassemble or replace the components, they will find it difficult to start the vehicle without the key.
[0081] Based on UWB signals, the activation code is verified to prevent others from counterfeiting UWB transmitters under the same protocol to activate two-wheeled vehicles, thereby improving theft prevention.
[0082] This embodiment adds a layer of security to the existing countermeasures against towing of the two-wheeled vehicle, with self-encryption and power-off measures triggered by lifting or moving. This expands the vehicle's anti-theft system from ground-level protection to off-ground transport protection, thus improving the anti-theft capabilities of the two-wheeled vehicle.
[0083] In at least one embodiment of this application, the UWB keyless proximity start / stop and anti-tampering locking method applied to two-wheeled vehicles further includes: S305. If there is no UWB signal for the corresponding two-wheeled vehicle UWB key, a locking control command is generated to control the preset component set to enter the locked state and cut off the power.
[0084] Please refer to Figures 1-3 In this embodiment, when the vehicle has entered the aforementioned anti-theft or anti-moving process, and the controller has determined that the current scenario requires upgrading the protection of the vehicle's key functions, the vehicle controller will first attempt to search within the set UWB receiving range for the existence of a UWB signal from a two-wheeled vehicle UWB key that has been bound to the vehicle. If no corresponding UWB signal is found within the specified detection time window, or if the detected signal cannot match the vehicle's binding identifier, the controller can directly determine that the person currently moving, disassembling, or lifting the vehicle is not a legitimate user or the vehicle owner.
[0085] Based on this determination, the controller no longer needs to go through the step of verifying the original activation code, but directly generates a lock-up control command, pulling all the preset components that are pre-set in the vehicle and strongly associated with driving, power supply and control into the lock-up state.
[0086] At the same time, a power-off command is issued to the power paths associated with these components, putting them in a controlled shutdown state that is unavailable, inactive, and inoperable until they are re-authenticated with a valid UWB key.
[0087] As long as the vehicle's exclusive UWB key is not detected, a set of interconnected core components will be locked and powered off immediately. This prevents thieves from powering on the vehicle, riding it away without a key, or reusing the key electronic components, even if they have already obtained the vehicle. This greatly improves theft prevention.
[0088] In at least one embodiment of this application, the specific steps for detecting whether the two-wheeled vehicle is off the ground after executing the anti-theft control command include: S301. Obtain the tire pressure when executing the locking command and generate the initial tire pressure.
[0089] S302. After executing the anti-theft control command, obtain the tire pressure of the two-wheeled vehicle during the detection process and generate the tire pressure to be checked.
[0090] S303. Compare the tire pressure to be checked with the initial tire pressure. If the tire pressure to be checked is less than the initial tire pressure, it is determined that the tire is off the ground.
[0091] Please refer to Figures 1-3 In this embodiment, when the vehicle issues a locking command for the first time and the wheels are still on the ground, the vehicle controller calls the tire pressure detection module (which can be a TPMS pressure sensor built into the tire or an on-board tire pressure acquisition device connected to the rim and axle) to read the actual tire pressure of the wheel at this time, and records this tire pressure value as the initial tire pressure. This initial tire pressure corresponds to the reference pressure when the vehicle is in a locked state but still on the ground and there is heavy pressure from the vehicle on the tire.
[0092] Subsequently, when the vehicle executes an anti-theft control command (such as reverse drive or braking disturbance), the controller obtains the current tire pressure from the same tire pressure detection module again within a set detection time and generates the tire pressure to be checked.
[0093] The controller compares the tire pressure to be checked with the previously recorded initial tire pressure. If it finds that the tire pressure to be checked is significantly lower than the initial tire pressure (i.e., the tire pressure has dropped), it can determine that the ground reaction force on the tire or the weight of the whole vehicle has decreased. Combined with the premise that the vehicle is in anti-theft mode at this time, it can be reasonably determined that the vehicle has been lifted off the ground or at least some wheels have been lifted off the ground, and thus output the judgment result of being lifted off the ground.
[0094] Compared to sensor methods that rely on tilt angle and acceleration, which are easily affected by uneven ground, wind, and minor collisions, tire pressure drops noticeably when the wheels are actually off the ground. This provides a more accurate assessment of whether the vehicle has truly lost ground support, reducing false alarms.
[0095] If the vehicle is in anti-theft mode, has indeed been lifted off the ground, and there is no valid UWB key or activation code on site, it will immediately enter a high-level locking state, preventing thieves from restoring the vehicle's functionality even if they lift it away. This significantly enhances the anti-theft capability of the entire UWB keyless anti-moving method.
[0096] In at least one embodiment of this application, the UWB keyless proximity start / stop and anti-tampering locking method applied to two-wheeled vehicles further includes: S306. Compare the tire pressure to be checked with the initial tire pressure. If the tire pressure to be checked is not less than the initial tire pressure, it is determined that the tire has not left the ground.
[0097] Please refer to Figures 1-3In this embodiment, when the vehicle controller compares the tire pressure to be checked with the initial tire pressure and finds that the tire pressure to be checked has not decreased, that is, when the tire pressure to be checked is not less than the initial tire pressure, it can be considered that the ground support force borne by the wheel has not decreased significantly, and the vehicle still maintains a force and ground state that is basically the same as when the locking control is executed. At this time, the controller makes the judgment of "not off the ground" and does not enter the subsequent protection process such as high-level locking, component binding, and power cut-off after the vehicle is off the ground. The vehicle can remain in the original locking / anti-moving monitoring state.
[0098] The system ensures that the tire pressure is not less than the initial tire pressure and remains silent during normal parking and legal minor operations, avoiding misjudgments caused by someone gently touching the vehicle, slight bumps on the ground, wind shaking, or the owner adjusting the vehicle while stationary.
[0099] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0100] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
