Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle design, and more particularly to a two-wheeled vehicle and its control method. Background Technology
[0002] Two-wheeled vehicles such as electric bicycles, two-wheeled gasoline motorcycles, and two-wheeled electric motorcycles are generally equipped with steering locks. These steering locks are typically steering wheel locks with retractable bolts. The most traditional steering wheel locks are purely mechanical, using a key to turn the lock cylinder to extend or retract the bolt. This structure is relatively cumbersome and of lower quality. Therefore, as electric vehicles become increasingly intelligent, remote-controlled intelligent electronic steering wheel locks have also appeared on the market. These electronic steering wheel locks use a remote control circuit to control the motor's rotation, causing the bolt to extend or retract into the housing.
[0003] In related technologies, electronic steering wheel locks cannot detect the working status of the bolt and motor when locking or unlocking, thus making it impossible to know whether the electronic steering wheel lock is working properly, which poses a safety hazard during the operation of two-wheeled vehicles. Summary of the Invention
[0004] In view of the above, in order to solve at least one of the above technical problems, this application provides a two-wheeled vehicle and its control method, which can detect the working status of the locking tongue and drive components, ensure the normal operation of the steering locking device, and thus ensure the driving safety of the two-wheeled vehicle.
[0005] This application provides a two-wheeled vehicle, including: a frame; wheels, including front wheels and rear wheels; a steering system supported by the frame for controlling the direction of travel of the two-wheeled vehicle, the front wheels being connected to the steering system; and a steering locking device for locking or unlocking the steering system. The steering locking device includes a latch, a transmission mechanism, a drive assembly, and a detection module. The latch is driven by the transmission mechanism, and the drive assembly is driven by the transmission mechanism. The drive assembly controls the extension and retraction of the latch to lock or unlock the steering system by driving the transmission mechanism. The drive assembly includes a motor. The steering locking device has a locked state and an unlocked state. The transmission mechanism includes a motor drive mechanism and a latch drive mechanism. When the steering locking device is in the locked state, both the latch drive mechanism and the motor drive mechanism are spaced apart from the detection module. When the steering locking device is in the unlocked state, both the latch drive mechanism and the motor drive mechanism abut against the detection module.
[0006] Compared with the prior art, the embodiments of this application have at least the following advantages: By setting a detection module, when the steering locking device is in the locked state, it is necessary to ensure that the latch extends to lock the steering system. By controlling the latch transmission mechanism and the motor transmission mechanism to be spaced apart from the detection module, that is, the driving direction of the drive component to the transmission mechanism is consistent with the extension and retraction direction of the latch when the steering locking device is in the locked state, it can be known that the steering locking device is in a normal working state. When the steering locking device is in the unlocked state, it is necessary to ensure that the latch retracts to unlock the steering system. By controlling the latch transmission mechanism and the motor transmission mechanism to abut against the detection module, that is, the driving direction of the drive component to the transmission mechanism is consistent with the extension and retraction direction of the latch when the steering locking device is in the unlocked state, it can be known that the steering locking device is in a normal working state, thus ensuring the driving safety of the two-wheeled vehicle.
[0007] Furthermore, the drive assembly includes a motor gear, and the motor transmission mechanism is provided with a meshing portion that cooperates with the motor gear.
[0008] Furthermore, both the motor drive mechanism and the locking tongue drive mechanism include an elastic element and a push rod elastically connected to the elastic element; when the steering locking device is in the unlocked state, the push rods of the motor drive mechanism and the locking tongue drive mechanism abut against the detection module.
[0009] Furthermore, the detection module includes a motor detection micro switch and a latch detection micro switch; when the steering locking device is in the locked state, the motor transmission mechanism is spaced apart from the motor detection micro switch, and the latch transmission mechanism is spaced apart from the latch detection micro switch, both of which are in the open state; when the steering locking device is in the unlocked state, the motor transmission mechanism abuts against the motor detection micro switch, and the latch transmission mechanism abuts against the latch detection micro switch, both of which are in the closed state.
[0010] Furthermore, the two-wheeled vehicle also includes a control system, which controls the power-on and power-off of the two-wheeled vehicle. The control system is connected to the motor detection micro switch and the latch detection micro switch, respectively. When the steering locking device changes from the locked state to the unlocked state, the control system detects that both the motor detection micro switch and the latch detection micro switch change from the open state to the closed state, and the control system controls the two-wheeled vehicle to power on. When the steering locking device changes from the unlocked state to the locked state, the control system detects that both the motor detection micro switch and the latch detection micro switch change from the closed state to the open state.
[0011] Furthermore, when the steering locking device transitions from the locked state to the unlocked state, the control system is also configured to: send a fault warning message when it detects that at least one of the motor detection micro switch and the latch detection micro switch has not transitioned from the conducting state to the disconnected state.
[0012] Furthermore, when the steering locking device transitions from the unlocked state to the locked state, the control system is also configured to: send a fault warning message when it detects that at least one of the motor detection micro switch and the latch detection micro switch has not transitioned from the disconnected state to the on state.
[0013] Furthermore, during the operation of the two-wheeled vehicle, the control system is also used to: detect the state of the motor detection micro switch and the lock tongue detection micro switch respectively; when it is detected that at least one of the motor detection micro switch and the lock tongue detection micro switch is not in the conducting state, control the steering locking device to switch to the unlocked state and send a fault prompt message.
[0014] Furthermore, the steering locking device also includes a circuit board connected to an external power source; the circuit board contacts the detection module to energize the detection module.
[0015] A second aspect of this application also provides a two-wheeled vehicle control method, the two-wheeled vehicle comprising: a steering system supported by a frame for controlling the direction of travel of the two-wheeled vehicle, the front wheel being connected to the steering system; and a steering locking device for locking or unlocking the steering system; the steering locking device comprising a latch, a transmission mechanism, a drive assembly, and a detection module, the latch being drively connected to the transmission mechanism, the drive assembly being drively connected to the transmission mechanism, the drive assembly controlling the extension and retraction of the latch to lock or unlock the steering system by driving the transmission mechanism to move, the drive assembly comprising a motor; and the steering locking device including a locked state. The steering locking device is in the locked state, and in the unlocked state; the transmission mechanism includes a motor transmission mechanism and a latch transmission mechanism; the control method includes: when the steering locking device is in the locked state, controlling the drive component to drive the motor transmission mechanism and the latch transmission mechanism to move until they are spaced apart from the detection module, and controlling the detection module to detect that the latch is in the extended state and the drive component is in the forward running state; when the steering locking device is in the unlocked state, controlling the drive component to drive the motor transmission mechanism and the latch transmission mechanism to move until they abut against the detection module, and controlling the detection module to detect that the latch is in the retracted state and the drive component is in the reverse running state.
[0016] Understandably, the two-wheeled vehicle control method of the second aspect provided above corresponds to the two-wheeled vehicle of the first aspect above. Therefore, the beneficial effects it can achieve can be referred to the beneficial effects in the corresponding structure provided above, and will not be repeated here. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0025] The following description sets forth many specific details to provide a full understanding of this application. The described embodiments are only some, not all, of the embodiments of this application.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.
[0027] It should be further noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
[0028] The terms "first," "second," etc., used in the specification, claims, and drawings of this application are used to distinguish similar objects, rather than to describe a specific order or sequence.
[0029] For ease of understanding, the following exemplary descriptions of some concepts related to the embodiments of this application are provided for reference.
[0030] Vehicle Control Unit (VCU): The VCU monitors the actions of the lower-level component control modules and is responsible for the normal driving of the two-wheeled vehicle, brake energy feedback, vehicle power management, network management, fault diagnosis and handling, and monitoring of the two-wheeled vehicle status. It can ensure that the two-wheeled vehicle can work normally and stably with good power and reliability.
[0031] A motor control unit (MCU) controls the rotation of a motor based on commands from the VCU or signals acquired from it. Generally, the MCU can be separate from the drive motor and connected via three-phase lines; alternatively, the MCU can be directly mounted on the drive motor, saving space and reducing costs, but increasing the complexity of maintenance and replacement.
[0032] Please refer to Figure 1 and Figure 2 As shown, the two-wheeled vehicle 100 provided in this application embodiment includes, but is not limited to: a steering locking device 11, a frame 12, wheels 13, and a steering system 14. The wheels 13 include a front wheel 131 and a rear wheel 132; the steering system 14 is supported by the frame 12 and is used to control the running direction of the two-wheeled vehicle 100, with the front wheel 131 connected to the steering system 14; the steering locking device 11 is used to lock or unlock the steering system 14.
[0033] Please refer to this again. Figure 2 The steering locking device 11 includes a drive assembly 112, a locking tongue 1131, a transmission mechanism, and a detection module 114. It should be noted that the transmission mechanism includes... Figure 2The motor drive mechanism 1132 and the latch drive mechanism 1133 are shown. Specifically, the latch 1131 is drive-connected to the latch drive mechanism 1133, and the drive assembly 112 is drive-connected to the motor drive mechanism 1132. The drive assembly 112 drives the motor drive mechanism 1132 to move, which in turn drives the latch drive mechanism 1133 to move, thereby controlling the extension and retraction of the latch 1131.
[0034] The steering locking device 11 includes a locked state and an unlocked state. When the steering locking device 11 is in the locked state, the motor drive mechanism 1132 and the lock tongue drive mechanism 1133 are spaced apart from the detection module 114. When the steering locking device 11 is in the unlocked state, the motor drive mechanism 1132 and the lock tongue drive mechanism 1133 are in contact with the detection module 114.
[0035] Please see again Figure 2 The drive assembly 112 includes a motor 1121 and a motor gear 1122. The motor transmission mechanism 1132 is provided with a meshing part 1132e that cooperates with the motor gear 1122. The rotation of the motor 1121 drives the motor gear 1122 to rotate. The motor gear 1122 drives the meshing part 1132e to move through gear transmission, so that the motor transmission mechanism 1132 moves. The motor transmission mechanism 1132 drives the locking tongue transmission mechanism 1133 to move, thereby controlling the extension and retraction of the locking tongue 1131.
[0036] Furthermore, Figure 2 The detection module 114 shown includes a motor detection micro switch 1141 and a latch detection micro switch 1142. When the steering lock device 11 is in the locked state, the motor transmission mechanism 1132 is spaced apart from the motor detection micro switch 1141, and the latch transmission mechanism 1133 is spaced apart from the latch detection micro switch 1142. Both the motor detection micro switch 1141 and the latch detection micro switch 1142 are in the open state. When the steering lock device 11 is in the unlocked state, the motor transmission mechanism 1132 abuts against the motor detection micro switch 1141, and the latch transmission mechanism 1133 abuts against the latch detection micro switch 1142. Both the motor detection micro switch 1141 and the latch detection micro switch 1142 are in the closed state.
[0037] To facilitate understanding, the following will be combined with... Figure 3 The working process of the steering locking device 11 in this application is described in detail below: Please refer to this as well. Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the steering locking device 11 in the unlocked state. Figure 3 This is a schematic diagram of the steering locking device 11 in the locked state. The specific working process of the locking system 11 is as follows: (1) When the steering lock device 11 needs to be switched to the unlocked state, the motor 1121 rotates to drive the motor gear 1122 to rotate counterclockwise. The motor gear 1122 drives the meshing part 1132e to move in the direction close to the motor detection micro switch 1141 through gear transmission, so that the latch transmission mechanism 1133 follows the movement of the motor transmission mechanism 1132 in the direction close to the latch detection micro switch 1142, until the motor transmission mechanism 1132 abuts against the motor detection micro switch 1141, and the latch transmission mechanism 1133 abuts against the latch detection micro switch 1142. Both the motor detection micro switch 1141 and the latch detection micro switch 1142 are in the conducting state. Figure 2 It can be seen that when the steering locking device 11 is in the unlocked state, the locking tongue 1131 is housed in the lock housing 111 of the steering locking device 11.
[0038] (2) When the steering lock device 11 needs to be switched to the locked state, the motor 1121 rotates, driving the motor gear 1122 to rotate clockwise. The motor gear 1122 drives the meshing part 1132e to move away from the motor detection micro switch 1141 through gear transmission, so that the latch transmission mechanism 1133 follows the movement of the motor transmission mechanism 1132 and moves away from the latch detection micro switch 1142 until the motor transmission mechanism 1132 is separated from the motor detection micro switch 1141, and the latch transmission mechanism 1133 is separated from the latch detection micro switch 1142. Both the motor detection micro switch 1141 and the latch detection micro switch 1142 are in the open state. Figure 3 It can be seen that when the steering locking device 11 is in the locked state, the locking tongue 1131 extends at least partially out of the lock housing 111 of the steering locking device 11.
[0039] It should be noted that the principle that the steering lock device 11 can be determined to be successfully unlocked when both the motor detection micro switch 1141 and the lock tongue detection micro switch 1142 are in the on state, and the steering lock device 11 can be determined to be successfully locked when both the motor detection micro switch 1141 and the lock tongue detection micro switch 1142 are in the off state, is described in detail in subsequent embodiments. To avoid repetition, it will not be repeated here.
[0040] In some embodiments, the steering locking device 11 is a steering lock. For ease of understanding, the following description is in conjunction with... Figure 4 The structure of the faucet lock 11 provided in this embodiment will be described in detail below: Please refer to Figure 4 , Figure 4 An exploded view of the steering locking device 11 provided in an embodiment of this application. Figure 4The steering lock device 11 shown is a throttle lock, which also includes a lock housing 111, a lower housing 115, and an upper housing 116. The drive assembly 112, the latch 1131, the motor transmission mechanism 1132, the latch transmission mechanism 1133, and the detection module 114 are all housed within the lock housing 111. Specifically, the motor 1121 and the motor gear 1122 are housed within the receiving space formed by the lower housing 115 and the upper housing 116. The lower housing 115 and the upper housing 116 cooperate to be housed within the lock housing 111. The upper housing 116 is provided with a microswitch receiving slot 1160, in which the motor detection microswitch 1141 and the latch detection microswitch 1142 are both housed.
[0041] In some embodiments, the steering locking device 11 further includes a circuit board 115, which is disposed within a micro switch receiving slot 1160. A motor detection micro switch 1141 and a latch detection micro switch 1142 are disposed on the side of the circuit board 115 away from the upper housing 116, and are in contact with the circuit board. Since the circuit board 115 is connected to an external power source, the motor detection micro switch 1141 and the latch detection micro switch 1142 can be energized. This structure allows the circuit board 115 to function as a conductor, facilitating the soldering of the motor detection micro switch 1141 and the latch detection micro switch 1142, improving the production efficiency of the steering locking device 11, and reducing the production failure rate of the steering locking device 11.
[0042] It is worth noting that, Figure 4The motor transmission mechanism 1132 shown includes a first elastic element 1132a and a first push rod 1132b elastically connected to the first elastic element 1132a. The latch transmission mechanism 1133 includes a second elastic element 1133a and a second push rod 1133b elastically connected to the first elastic element 1133a. The motor detection micro switch 1141 includes a first protrusion 1141a, and the latch detection micro switch 1142 includes a second protrusion 1142b. When the steering locking device 11 needs to be switched to the unlocked state... When the motor 1121 rotates, it drives the motor gear 1122 to rotate counterclockwise. The motor gear 1122, through gear transmission, drives the meshing part 1132e to move in the direction close to the motor detection micro switch 1141. This causes the locking tongue transmission mechanism 1133 to follow the movement of the motor transmission mechanism 1132 in the direction close to the locking tongue detection micro switch 1142 until the first push rod 1132b contacts the first protrusion 1141a and the second push rod 1133b contacts the second protrusion 1142b. This structure transforms the rigid contact between the transmission mechanism and the micro switch into an elastic contact, preventing damage to the motor detection micro switch 1141 and the locking tongue detection micro switch 1142 from repeated rigid contact. This improves the service life of the motor detection micro switch 1141 and the locking tongue detection micro switch 1142, thereby enhancing the reliability of the steering lock device 11.
[0043] Please refer to this as well. Figures 5 to 6 , Figure 5 This is a partial structural schematic diagram of the motor drive mechanism 1132 and the latch drive mechanism 1133 provided in the embodiments of this application. The motor drive mechanism 1132 further includes a first receiving groove 1132c, in which a first elastic member 1132a and a first push rod 1132b are received; the latch drive mechanism 1133 further includes a second receiving groove 1133c, in which a second elastic member 1133a and a second push rod 1133b are received. The motor drive mechanism 1132 further includes a third elastic member 1132d, through which the motor drive mechanism 1132 is elastically connected to the latch drive mechanism 1133.
[0044] like Figure 6The diagram shows a partial structural schematic of the motor transmission mechanism 1132 provided in this embodiment of the application. The third elastic element 1132d is held in the groove of the motor transmission mechanism 1132. Since the motor 1121, motor gear 1122, motor transmission mechanism 1132, and locking tongue transmission mechanism 1133 are all connected by transmission, if the transmission connection between the motor transmission mechanism 1132 and the locking tongue transmission mechanism 1133 is rigid, it will cause the motor 1121 to be unable to rotate if the locking tongue 1131 is stuck when the working state of the steering locking device 11 is changed, which may lead to damage to the motor 1121. With this structural design, the motor 1121 can still rotate when the locking tongue 1131 is stuck, which further improves the reliability of the steering locking device 11.
[0045] In some embodiments, the two-wheeled vehicle 100 further includes a control system (not shown), which controls the power-on and power-off of the two-wheeled vehicle 100. The control system is connected to the motor detection micro switch 1141 and the latch detection micro switch 1142, respectively. When the steering locking device 11 changes from the locked state to the unlocked state, the control system detects that both the motor detection micro switch 1141 and the latch detection micro switch 1142 change from the open state to the on state, and the control system controls the two-wheeled vehicle 100 to power on. When the steering locking device 11 changes from the unlocked state to the locked state, the control system detects that both the motor detection micro switch 1141 and the latch detection micro switch 1142 change from the on state to the open state.
[0046] As described above, the motor detection microswitch 1141 and the latch detection microswitch 1142 are in contact with the circuit board. Since the circuit board is connected to an external power supply, the motor detection microswitch 1141 and the latch detection microswitch 1142 can be energized. When the motor detection microswitch 1141 is not abutted by the motor transmission mechanism 1132, the motor detection microswitch 1141 is in the open state. At this time, the control system detects that the voltage difference of the motor detection microswitch 1141 is 0. When the motor detection microswitch 1141 is abutted by the motor transmission mechanism 1132, the motor detection microswitch 1141 is in the closed state. At this time, the control system detects that there is a voltage difference in the motor detection microswitch 1141. Therefore, the control system can detect whether the motor detection microswitch 1141 is abutted by the motor transmission mechanism 1132 by detecting whether the voltage difference of the motor detection microswitch 1141 is 0, thereby knowing the working state of the motor 1121. Similarly, the control system can detect whether the latch detection micro switch 1142 is abutted by the latch transmission mechanism 1133 by detecting whether the voltage difference of the latch detection micro switch 1142 is 0, thereby determining the position of the latch 1131.
[0047] It is understood that this embodiment does not specifically limit the type of control system. The control system can be a vehicle controller, motor controller, instrument, etc., and can be set according to actual needs.
[0048] In some embodiments, when the steering locking device 11 transitions from a locked state to an unlocked state, the control system is further configured to: send a fault warning message when it detects that at least one of the motor detection micro switch 1141 and the latch detection micro switch 1142 has not transitioned from a conducting state to a disconnected state.
[0049] In some embodiments, when the steering locking device 11 transitions from an unlocked state to a locked state, the control system is further configured to: send a fault warning message when it detects that at least one of the motor detection micro switch 1141 and the latch detection micro switch 1142 has not transitioned from an open state to an on state.
[0050] In some embodiments, during the operation of the two-wheeled vehicle 100, the control system is further configured to: detect the states of the motor detection micro switch 1141 and the lock tongue detection micro switch 1142 respectively; when at least one of the motor detection micro switch 1141 and the lock tongue detection micro switch 1142 is detected to be not in the conducting state, control the steering locking device 11 to switch to the unlocked state and send a fault prompt message.
[0051] It is understood that this embodiment does not specifically limit the way the control system sends fault prompt information. The control system can prompt the user of a fault by displaying text or patterns on the instrument panel of the two-wheeled vehicle 100, or it can control the speaker of the two-wheeled vehicle 100 to send a voice prompt to the user of a fault.
[0052] To facilitate understanding, the following will be combined with... Figure 7 This embodiment provides a detailed explanation of how it detects the status of the steering lock device 11 and sends fault warning messages: Please refer to Figure 7 This is a schematic diagram of the control logic of the steering lock 11 when the steering lock 11 provided in this application embodiment is a steering lock. When the steering lock 11 needs to be switched to the unlocked state (i.e., perform unlocking) or needs to be switched to the locked state (i.e., perform locking), the control system detects the motor unlocking signal corresponding to the motor detection micro switch 1141 and the lock tongue unlocking signal corresponding to the lock tongue detection micro switch 1142.
[0053] Specifically, when the motor unlocking signal of the motor detection micro switch 1141 is 0, it indicates that the motor detection micro switch 1141 is in the off state; when the motor unlocking signal of the motor detection micro switch 1141 is 1, it indicates that the motor detection micro switch 1141 is in the on state. Similarly, when the lock tongue detection micro switch 1142's lock tongue unlocking signal is 0, it indicates that the lock tongue detection micro switch 1142 is in the off state; when the lock tongue detection micro switch 1142's lock tongue unlocking signal is 1, it indicates that the lock tongue detection micro switch 1142 is in the on state.
[0054] More specifically, during the unlocking process of the faucet lock 11, if the motor rotation of motor 1121 is... Figure 7 The "from locked to unlocked" signifies that the motor 1121 drives the motor gear 1122 to rotate counterclockwise. The motor gear 1122 drives the meshing part 1132e to move in the direction close to the motor detection micro switch 1141 through gear transmission until the first push rod 1132b of the motor transmission mechanism 1132 contacts the first protrusion 1141a of the motor detection micro switch 1141. At this time, the motor detection micro switch 1141 changes from the open state to the on state. The control system detects that there is a voltage difference in the motor detection micro switch 1141, that is, it detects that the motor unlock signal changes from 0 to 1. Furthermore, the latch transmission mechanism 1133 moves along the direction close to the latch detection micro switch 1142, following the movement of the motor transmission mechanism 1132, until the second push rod 1133b of the latch transmission mechanism 1133 contacts the second protrusion 1142b of the latch detection micro switch 1142. At this time, the latch detection micro switch 1142 changes from the open state to the on state. The control system detects that there is a voltage difference in the latch detection micro switch 1142, that is, it detects that the latch unlocking signal changes from 0 to 1.
[0055] As can be seen from the control logic of the faucet lock 11 for unlocking shown in Figure 7 and the above description, the unlocking process of the faucet lock 11 includes the following control logic: (1) During the unlocking process of the auger lock 11, the control system detects that the motor unlocking signal changes from 0 to 1 and the lock tongue unlocking signal changes from 0 to 1, indicating that the auger lock 11 is performing the unlocking process normally, and the control system controls the two-wheeled vehicle 100 to be powered on.
[0056] (2) During the unlocking process of the auger lock 11, the control system detects that the motor unlocking signal changes from 0 to 1, but the lock tongue unlocking signal is still 0. The control system detects that the auger lock 11 is in an abnormal state, and the control system detects that the possible cause of the auger lock 11 fault is that the lock tongue 1131 is stuck. The control system informs the user to shake the auger of the two-wheeled vehicle 100 through the text prompt or voice prompt of the instrument. If the control system detects that the lock tongue unlocking signal is still 0 after the preset time after reminding the user (e.g., after 5 seconds), the control system controls the two-wheeled vehicle 100 to send a fault prompt message.
[0057] (3) During the unlocking process of the auger lock 11, the control system detects that the motor unlocking signal is still 0 and the lock tongue unlocking signal changes from 0 to 1. The control system detects that the auger lock 11 is in an abnormal state and the control system detects that the possible cause of the auger lock 11 is that the motor detection micro switch 1141 is open. The control system controls the two-wheeled vehicle 100 to send a fault prompt message.
[0058] (4) During the unlocking process of the auger lock 11, the control system detects that the motor unlocking signal changes from 0 to 1, and the lock tongue unlocking signal remains unchanged at 1, indicating that the auger lock 11 is performing the unlocking process normally, and the control system controls the two-wheeled vehicle 100 to power on.
[0059] (5) During the unlocking process of the auger lock 11, the control system detected that the motor unlocking signal was always 1 and the lock tongue unlocking signal changed from 0 to 1. The control system detected that the auger lock 11 was in an abnormal state and the control system detected that the possible cause of the auger lock 11 was a short circuit of the lock tongue detection micro switch 1142. The control system controlled the two-wheeled vehicle 100 to send a fault prompt message.
[0060] (6) After the auger lock 11 is unlocked, the control system detects that the motor unlock signal is always 1 and the lock tongue unlock signal is always 1, indicating that the auger lock 11 is in the unlocked state, and the control system controls the two-wheeled vehicle 100 to be powered on normally.
[0061] (7) After the auger lock 11 is unlocked, the control system detects that the motor unlock signal is always 0 and the lock tongue unlock signal is always 0. The control system detects that the auger lock 11 is in an abnormal state and detects that the possible cause of the auger lock 11 failure is a fault in motor 1121 or a break in the motor 1121 wire. The control system controls the two-wheeled vehicle 100 to send a fault prompt message.
[0062] During the locking process of the faucet lock 11, if the motor rotation of motor 1121 is... Figure 7The "from unlock to lock" signifies that the motor 1121 drives the motor gear 1122 to rotate clockwise. The motor gear 1122 drives the meshing part 1132e to move away from the motor detection micro switch 1141 through gear transmission until the first push rod 1132b of the motor transmission mechanism 1132 is separated from the first protrusion 1141a of the motor detection micro switch 1141. At this time, the motor detection micro switch 1141 changes from the on state to the off state. The control system detects that the voltage difference of the motor detection micro switch 1141 is 0, that is, the motor unlock signal changes from 1 to 0. Furthermore, the latch transmission mechanism 1133 moves in a direction away from the latch detection micro switch 1142, following the movement of the motor transmission mechanism 1132, until the second push rod 1133b of the latch transmission mechanism 1133 is spaced apart from the second protrusion 1142b of the latch detection micro switch 1142. At this time, the latch detection micro switch 1142 changes from the on state to the off state, and the control system detects that the voltage difference of the latch detection micro switch 1142 is 0, that is, it detects that the latch unlocking signal changes from 1 to 0.
[0063] As can be seen from the control logic of the faucet lock 11 in Figure 7 and the above description, the following control logics are included in the process of the faucet lock 11 locking: (1) During the locking process of the faucet lock 11, the control system detects that the motor unlocking signal changes from 1 to 0 and the lock tongue unlocking signal changes from 1 to 0, indicating that the locking process of the faucet lock 11 is normal.
[0064] (2) During the locking process of the auger lock 11, the control system detects that the motor unlocking signal changes from 1 to 0, but the lock tongue unlocking signal is still 1. The control system detects that the auger lock 11 is in an abnormal state, and the control system detects that the possible cause of the auger lock 11 fault is that the lock tongue 1131 is stuck or the lock tongue 1131 is lifted by the auger lock cable. Since the two-wheeled vehicle 100 has been powered off at this time, the control system can choose not to control the two-wheeled vehicle 100 to send fault prompt information.
[0065] (3) During the locking process of the auger lock 11, the control system detects that the motor unlocking signal changes from 1 to 0, and the lock tongue unlocking signal is still 0. The control system detects that the auger lock 11 is in an abnormal state, and the control system detects that the possible cause of the auger lock 11 fault is that the lock tongue detection micro switch 1142 is short-circuited or the lock tongue 1131 is blocked. Since the two-wheeled vehicle 100 has been powered off at this time, the control system can choose not to control the two-wheeled vehicle 100 to send fault prompt information.
[0066] (4) During the locking process of the auger lock 11, the control system detects that the motor unlocking signal is still 1 and the lock tongue unlocking signal changes from 1 to 0. The control system detects that the auger lock 11 is in an abnormal state. The control system detects that the possible cause of the auger lock 11 is a short circuit in the motor detection micro switch 1141. Since the short circuit of the motor detection micro switch 1141 is quite serious, even if the two-wheeled vehicle 100 is powered off, the control system will still control the two-wheeled vehicle 100 to send a fault prompt message.
[0067] (5) During the locking process of the auger lock 11, the control system detected that the motor unlocking signal was always 0 and the lock tongue unlocking signal changed from 1 to 0. The control system detected that the auger lock 11 was in an abnormal state. The control system detected that the possible cause of the auger lock 11 was that the motor detection micro switch 1141 was open circuit. Since the open circuit of the motor detection micro switch 1141 was quite serious, even if the two-wheeled vehicle 100 was powered off, the control system would still control the two-wheeled vehicle 100 to send a fault prompt message.
[0068] (6) After the faucet lock 11 is locked, the control system detects that the motor unlock signal is always 0 and the lock tongue unlock signal is always 0. The control system detects that the faucet lock 11 is in an abnormal state. The control system detects that the possible causes of the faucet lock 11 failure are motor 1121 failure or faucet lock 11 being in a locked state.
[0069] (7) After the auger lock 11 is locked, the control system detects that the motor unlock signal is always 1 and the lock tongue unlock signal is always 1. The control system detects that the auger lock 11 is in an abnormal state. The control system detects that the possible cause of the auger lock 11 failure is a fault in motor 1121 or a break in the motor 1121 wire. The control system controls the two-wheeled vehicle 100 to send a locking failure message.
[0070] It should also be noted that during the operation of the two-wheeled vehicle 100, the control system will also monitor the status of the steering lock 11 in real time, such as... Figure 7 As shown, the following control logics are included during the operation of the two-wheeled vehicle 100: (1) The control system detects that the motor unlock signal changes from 1 to 0, and the lock tongue unlock signal is always 1. The control system detects that the steer lock 11 is in an abnormal state, and the control system detects that the possible cause of the steer lock 11 failure is that the motor detection micro switch 1141 is open. The control system controls the steer lock 11 to switch to the unlock state and controls the two-wheeled vehicle to send a fault prompt message.
[0071] (2) The control system detected that the motor unlock signal was always 1 and the lock tongue unlock signal changed from 1 to 0. The control system detected that the state of the steer lock 11 was abnormal. The control system detected that the possible cause of the fault of the steer lock 11 was that the lock tongue detection micro switch 1142 was open. The control system controlled the steer lock 11 to switch to the unlocked state and controlled the two-wheeled vehicle to send fault prompt information.
[0072] (3) The control system detects that the motor unlock signal changes from 1 to 0 and the lock tongue unlock signal changes from 1 to 0. The control system detects that the state of the steering wheel lock 11 is abnormal and the possible cause of the failure of the steering wheel lock 11 is that the steering wheel lock 11 is accidentally locked. The control system controls the steering wheel lock 11 to switch to the unlocked state and controls the two-wheeled vehicle to send a fault prompt message.
[0073] This application also provides a two-wheeled vehicle control method applied to the aforementioned two-wheeled vehicle 100. The control method includes: when the steering lock device is in a locked state, controlling the drive assembly to move the drive motor transmission mechanism and the lock tongue transmission mechanism to a distance from the detection module, and controlling the detection module to detect that the lock tongue is in an extended state and the drive assembly is in a forward running state; when the steering lock device is in an unlocked state, controlling the drive assembly to move the drive motor transmission mechanism and the lock tongue transmission mechanism to abut against the detection module, and controlling the detection module to detect that the lock tongue is in a retracted state and the drive assembly is in a reverse running state.
[0074] Compared with the prior art, the embodiments of this application have at least the following advantages: By setting a detection module, when the steering locking device is in the locked state, it is necessary to ensure that the latch extends to lock the steering system. By controlling the latch transmission mechanism and the motor transmission mechanism to be spaced apart from the detection module, that is, the driving direction of the drive component to the transmission mechanism is consistent with the extension and retraction direction of the latch when the steering locking device is in the locked state, it can be known that the steering locking device is in a normal working state. When the steering locking device is in the unlocked state, it is necessary to ensure that the latch retracts to unlock the steering system. By controlling the latch transmission mechanism and the motor transmission mechanism to abut against the detection module, that is, the driving direction of the drive component to the transmission mechanism is consistent with the extension and retraction direction of the latch when the steering locking device is in the unlocked state, it can be known that the steering locking device is in a normal working state, thus ensuring the driving safety of the two-wheeled vehicle.

Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application.
