Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a motorcycle. Background Technology

[0002] Currently, traditional motorcycles primarily use mechanical shifting methods such as hand-foot shifting and pedal shifting. Shifting requires manual operation and is cumbersome. For novice riders, especially when riding cruiser or touring motorcycles in complex conditions such as long-distance travel, rainy weather, or hill climbing, shifting can lead to fatigue, blurred vision, and decreased concentration. Mechanical shifting demands considerable skill and is difficult to operate, making it hard to ensure optimal shifting timing. Improper operation can affect the stability and safety of the motorcycle, potentially causing injury to the rider and passengers. Summary of the Invention

[0003] The purpose of this application is to provide a motorcycle whose gear shifting operation is simple and convenient, and does not affect the stability and safety of the motorcycle driving.

[0004] To achieve the above objectives, this application provides a motorcycle with a shifting system, including a frame, a power source, a suspension assembly, wheels, and a transmission assembly. The power source includes an engine supported by the frame, the suspension assembly is connected to the frame, the wheels are connected to the frame via the suspension assembly, and the transmission assembly is equipped with a shifting mechanism, connecting the wheels and the power source. The motorcycle also includes a shifting assembly, a detection assembly, an operating assembly, a control assembly, and an actuator. The shift assembly includes a shift mechanism connected to the transmission assembly and an actuator that drives the shift mechanism to shift gears. The shift mechanism performs the shift function, and the actuator receives the drive from the shift mechanism to achieve the final shift. The detection assembly includes a wheel speed sensor, an engine speed sensor, and a gear position sensor. The wheel speed sensor is used to detect the motorcycle speed, the engine speed sensor is used to detect the engine speed, and the gear position sensor is used to detect the gear position of the shift assembly. The operation assembly includes a shift switch for switching the gears of the shift assembly. The control assembly includes a shift controller for controlling the operation of the actuator. The control assembly can determine the target gear based on the engine speed detected by the detection assembly and the gear position of the shift assembly, and control the actuator to drive the shift mechanism to shift gears according to the determined target gear. The shift controller can receive shift commands sent by the shift switch and control the actuator to drive the shift mechanism to shift gears according to the shift commands.

[0005] Furthermore, the control component also includes an electronic control unit, which sends the received signals to the shift controller. After receiving the signals, the shift controller enters either an automatic shift mode or a manual shift mode. When the shift component enters the automatic shift mode, the shift controller determines the target gear based on the engine speed detected by the detection component and the gear position of the shift component, and sends a shift command to the actuator according to the determined target gear. When the shift component enters the manual shift mode, the shift controller receives the shift command sent by the shift switch and controls the actuator to drive the shift mechanism to shift gears according to the shift command.

[0006] Furthermore, the operating components include switches, handlebars, and instruments. The switches include a shift mode switch for switching the shifting mode of the shifting assembly and a shift / upshift switch for manually switching up or downshifting in manual shifting mode. The instrument displays the shift mode switch and is used to display motorcycle fault information, current gear, and target gear. The shift mode switch issues a shift mode switching command, and the shift controller enters automatic or manual shifting mode according to the shift mode switching command. The shift mode switch can be at least one of a screen key, button, knob, and toggle switch. Optionally, the shift mode switch is mounted on the handlebars, and the shift / upshift switch can be at least one of a button, knob, and toggle switch. The handlebars include a clutch for braking and shifting gears. In manual shifting mode, pressing the clutch engages the shift / upshift switch to complete upshifting or downshifting.

[0007] Furthermore, the detection components include a rain sensor, which is communicatively connected to the electronic control unit. When the rain sensor detects rainy road conditions, it sends a signal to the electronic control unit. When the electronic control unit determines that it has not received a shift signal or a turning signal, it sends a shift command to the shift controller to enter the automatic shift mode.

[0008] Furthermore, the detection component also includes an angle detection device, which is mounted on the frame or body panel. Optionally, the angle detection device is mounted on the centerline of the vehicle body. The angle detection device is communicatively connected to the electronic control unit. The angle detection device detects the rate of change of the vehicle body tilt angle. When the vehicle body tilt angle changes to zero, the angle detection device outputs a signal to the electronic control unit. After receiving the signal, the electronic control unit sends a shift command to the shift controller, and the shift controller enters the automatic shift mode.

[0009] Furthermore, the angle detection device includes a six-axis sensor and a gyroscope.

[0010] Furthermore, the actuator that drives the shift mechanism to shift gears includes a shift motor and a shift hub. The shift motor and the shift hub are connected by a transmission method. A detachable gear position sensor is installed on the shift hub. When the shift motor receives the shift command from the gear position sensor, it drives the shift hub to complete the shift.

[0011] Furthermore, the shift motor and shift hub utilize a worm gear transmission mechanism. The shift motor is connected to the worm gear, and its rotation drives a buffer worm gear. The rotation of the buffer worm gear causes the input gear to rotate, which in turn drives the output gear. The output gear transmits torque and speed to the shift hub gear via an idler gear. The shift hub gear is bolted to the shift hub, thereby driving the shift hub to rotate and move the shift fork, thus achieving gear shifting. The angle of the shift fork's movement driven by the rotation of the shift hub is coordinated with the command output by the gear position sensor. When the shift motor receives the shift command from the gear position sensor, it drives the shift hub to complete the shifting function.

[0012] Furthermore, the transmission methods achieved by the shift motor and shift hub include gear transmission.

[0013] Furthermore, shifting motors include brushed DC motors and brushless DC motors.

[0014] Furthermore, the detection component acquires the current motorcycle speed, engine speed, and gear position of the shift component, and obtains the currently received engine speed signal or shift component gear position signal. Based on the currently received engine speed and shift component gear position detected by the detection component, the target gear is determined, and the actuator is controlled to drive the shift mechanism to shift gears according to the determined target gear. The shift controller can receive shift commands sent by the shift switch and control the actuator to drive the shift mechanism to shift gears according to the shift commands.

[0015] Furthermore, the detection component acquires information including data transmitted from the rain sensor and the angle detection device, and sends the acquired signals to the electronic control unit. When the electronic control unit determines that it has not received the shift signal and turning signal transmitted by the shift switch, the shift controller enters the automatic shift mode.

[0016] The motorcycle can transmit signals to the control component based on the gear position signal and engine speed to control the shifting component to shift gears, so that the target gear and engine speed are matched. When the shifting controller receives the shifting command sent by the shifting switch, it can control the actuator to drive the shifting mechanism to shift gears according to the shifting command, so that the shifting operation of the motorcycle is simple and quick, and does not affect the stability and safety of the motorcycle driving.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of specific embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. However, these embodiments do not limit the invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0026] like Figure 1As shown, this application provides a motorcycle 10, including a frame 11, a power source 12, a suspension assembly 13, wheels 14, a transmission assembly 15, a shift assembly 16, a detection assembly, an operation assembly 18, a control assembly, and an actuator 20. The power source 12 includes an engine 121, which is supported by the frame 11. The suspension assembly 13 is connected to the frame 11, and the wheels 14 are connected to the frame 11 via the suspension assembly 13. The transmission assembly 15 connects the wheels 14 and the power source 12. The shift assembly 16 includes a shift mechanism connected to the transmission assembly 15 and an actuator for driving the shift mechanism to shift gears. The detection assembly includes an engine speed sensor and a gear position sensor 172. The engine speed sensor detects the engine speed of the engine 121, and the gear position sensor 172 detects the gear position of the shift assembly 16. The operating component 18 includes a switch 181, a handle 182, and an instrument 183. The switch 181 includes a shift mode switch 1811 for switching the shift mode of the shift component 16 and a shift switch 1812 for manually switching up or down in manual shift mode. The shift switch 1812 is mounted on the handle 182, which allows the driver to operate the operating component 18 at any time. The shift mode switch 1811 is used to issue a shift mode switching command. The shift controller 191 enters the automatic shift mode or the manual shift mode according to the shift mode switching command. The shift mode switch 1811 can be at least one of a screen key, a button, a knob, and a toggle switch. The upshift / downshift switch 1812 can be at least one of a button, a knob, and a toggle switch. The handlebar 182 is equipped with a clutch 1821 and an upshift / downshift switch 1812. The clutch 1821 is used for braking and upshifting / downshifting of the motorcycle 10. In manual shift mode, pressing the clutch and the upshift / downshift switch completes upshifting or downshifting of the motorcycle 10. The instrument 183 has a shift mode switch 1811 for switching the shift mode of the shift assembly 16. It is used to select between manual and automatic shift modes of the motorcycle 10 and displays information such as fault information, current gear, and target gear of the motorcycle 10. Optionally, the shift mode switch 1811 can be installed on the handlebar 182. The control component includes a shift controller 191 that controls the operation of the actuator. The control component can determine the target gear based on the engine speed 121 detected by the current receiving detection component and the gear position of the shift component 16, and control the actuator to drive the shift mechanism to shift gears according to the determined target gear. The shift controller 191 can also receive shift commands sent by the switch 181 and control the actuator to drive the shift mechanism to shift gears according to the shift commands.

[0027] The detection component includes a rain sensor 173, which is mounted at the front or highest point of the frame 11. Optionally, the rain sensor 173 can be mounted on the windshield or rearview mirror. When the rain sensor 173 detects rain, it sends a detection signal to the electronic control unit 192. In the absence of manual gear shifting or turning, the electronic control unit 192 sends a gear shift command to the gear shift controller 191 after receiving the signal from the rain sensor 173, switching to automatic gear shifting mode. The gear shift controller 191 automatically reads the current engine speed 121, the gear position sensor 172 reads the current gear, and the gear shift motor 201 drives the gear shift hub to switch gears so that the engine speed 121 matches the gear position of the gear position sensor 172 to achieve the gear shifting purpose.

[0028] The detection component includes an angle detection device 174, which is mounted on the frame 11 or the body panel. Optionally, the angle detection device is mounted on the centerline of the vehicle body, or alternatively, it is mounted at the center of gravity of the vehicle body. It is used to detect the rate of change of the vehicle body tilt angle. Optionally, the angle detection device 174 is a 6D sensor or a gyroscope. When the angle detection device 174 detects that the change in the vehicle body tilt angle has returned to zero, it determines that the motorcycle 10 is in a non-turning state, i.e., exiting a turn, and sends an exiting-turn signal to the electronic control unit 192. After receiving the signal from the angle detection device 174, the electronic control unit 192, in conjunction with the signal sent by the rain sensor 173, sends a shift command to the shift controller 191 to switch to automatic shifting mode. When the angle detection device 174 detects a large rate of change in the vehicle body tilt angle, it determines that the motorcycle 10 is not in a sharp turn, and the electronic control unit 192 does not send a shift command, allowing the shift controller 191 to enter automatic shifting mode.

[0029] like Figure 2As shown, the actuator 20 includes a shift motor 201, a gear position sensor 172, and a shift hub 202. The shift motor 201 and the shift hub 202 are connected by a worm gear transmission. The shift motor 201 is connected to the worm 203, and its rotation drives the buffer worm wheel 204. The rotation of the buffer worm wheel 204 causes the input gear 205 to rotate. The input gear 205 is connected to the fixed shaft 206, which drives the output gear 207 to rotate. The output gear 207 transmits torque and speed to the gear in the shift hub 202 through the idler wheel 208. The gear in the shift hub 202 is connected to the shift hub 202 through bolts 209, thereby driving the shift hub 202 to rotate and drive the shift fork to move, realizing gear switching. The angle of the shift fork's movement driven by the rotation of the shift hub 202 is coordinated with the command output by the gear position sensor 172. When the shift motor 201 receives the shift command from the gear position sensor 172, it drives the shift hub 202 to complete the shift and realize the shift function. The gear position sensor 172 is detachably mounted on the shift hub 202. Optionally, the transmission method also includes gear transmission. Optionally, the shift motor 201 includes, but is not limited to, a DC brushed motor and a DC brushless motor.

[0030] Optionally, the clutch 1821 is operated by an electric oil pump controlled by a button device or a switch device to operate the clutch cylinder piston. The electronic control unit 192 calculates the optimal engagement time and speed of the clutch based on feedback information such as the gear position of the shift mechanism and the speed detected by the engine speed sensor. The electronic control unit 192 drives the clutch cylinder piston to move, thereby realizing the action of the clutch 1821 and the shifting of the motorcycle.

[0031] like Figure 3As shown, the motorcycle 10 has two shifting modes: a manual shifting mode, replacing the traditional mode of shifting using foot-operated components, and an automatic shifting mode. In manual shifting mode, when the motorcycle's speed increases and the engine 121 reaches a preset speed range, the shifting mechanism needs to be in the corresponding gear to match the current speed. The rider presses the upshift switch 1812 to shift to the corresponding gear. The shift controller 191 receives the signal and controls the actuator to shift gears, matching the current speed with the current gear. When the motorcycle encounters an obstacle and needs to downshift, the rider presses the downshift switch 1812. The shift controller 191 receives the signal and controls the actuator to shift gears, matching the current speed with the current gear. The motorcycle uses automatic shifting mode, with different speed ranges preset and corresponding gears assigned to each range. The shift controller 191 automatically reads the engine speed signal of the engine 121. When the engine speed of the engine 121 is within the corresponding preset speed range, the shift controller 191 sends a signal to the actuator, which then drives the shifting mechanism to shift to the corresponding gear. For example, the motorcycle speed can be set to low, medium, and high speed ranges, with corresponding low, medium, and high gears. When the speed range changes from low to medium, the shifting mechanism switches to the medium gear. The rider does not need to operate the shift switch 1812 to change gears; by increasing the engine speed of the engine 121 to the preset value, the gear automatically changes and matches the current speed to achieve the target gear.

[0032] When the motorcycle 10 is started, it defaults to manual shifting mode. The driver can select different shifting modes according to different road conditions and driving needs. The driver can maintain manual shifting mode or switch to automatic shifting mode after starting the motorcycle 10. When the motorcycle is in manual shifting mode, the driver operates the shift switch 1812 on the operating component 18 to select the gear according to actual needs. After receiving the signal from the shift controller 191, the actuator responds, and the shift motor 201 drives the shift hub 202 to complete the shifting operation, so that the gear position signal received by the gear position sensor 172 matches the gear position of the shift switch 1812. When encountering uphill or other challenging road conditions, the motorcycle 10's climbing ability may be insufficient due to its heavy weight, outdated in-vehicle sensors, and the driver's lack of skill. This could lead to difficulties in gear shifting during uphill climbs or slippage when parking on a slope. If the driver finds manual shifting difficult or experiences a decreased driving experience due to uneven gear shifting, they can switch to automatic shifting mode. In this mode, the actuator receives the vehicle speed signal and drives the shift hub 202 to the appropriate gear. The automatic selection of the matching gear based on the motorcycle 10's speed range ensures that the motorcycle 10 has adequate power for climbing and prevents slippage. Switching to automatic shifting mode also prevents interruptions in climbing caused by incorrect gear shifting timing, improving vehicle stability. Under normal road conditions, the driver can also select the appropriate shifting mode based on their driving needs. For a more comfortable driving experience, the driver can choose manual shifting mode. For long journeys or when comfort is a priority, automatic shifting mode can be selected. Drivers can also switch to automatic shifting mode when they find it inconvenient to frequently operate the shift switch 1812 in congested areas or at traffic lights. After passing through such areas, the driver can switch back to manual shifting mode. When the motorcycle is switched to automatic shifting mode, the driver operates the shift mode switch 1811 on the operating component 18 to automatic shifting mode. Upon receiving the user's shift request, the shift controller 191 transmits the shift request and the current gear signal to the actuator. The actuator responds to the user's shifting intention, and the gear position sensor 172, in conjunction with the shift motor 201, drives the shift hub 202 to complete the shifting operation.

[0033] like Figure 4As shown, when the motorcycle 10 starts, it defaults to manual shifting mode. If the rider does not switch gears, and the rain sensor 173 detects rain during startup or movement, it sends a rain detection signal to the electronic control unit 192. Upon receiving the signal from the rain sensor 173, the electronic control unit 192 sends a signal command to the shift controller 191 to switch shifting modes. The shift controller 191 then enters automatic shifting mode according to the shifting mode command. The shift controller 191 automatically reads the current vehicle speed, engine speed 121, and power supply gear information, and controls the gear position sensor 172 in the actuator to work with the shift motor 201 to drive the shift hub 202 to switch gears, matching the gear to the current vehicle speed. However, when the motorcycle 10 is in manual shifting mode or the angle detection device 174 detects that the rate of change of the motorcycle 10's body tilt angle is not zero, the electronic control unit 192, upon receiving the signal from the angle detection device 174, will not send a signal to the shift controller 191 to switch shifting modes, and the shifting mode will not switch to automatic shifting mode. When the rain sensor 173 detects rain but no longer detects rain within a preset time, the driver can switch the motorcycle to manual shift mode by operating the control component 18 according to driving needs. The preset detection time for the rain sensor can be set by the user. When the rain sensor 173 does not detect rain, the motorcycle 10 remains in manual shift mode and does not switch to automatic shift mode.

[0034] like Figure 5 As shown, there are at least two ways to switch the motorcycle 10 from manual to automatic mode: one is by operating the shift mode switch 1811 on the operating component 18 to switch to automatic mode, and the other is by automatically switching to automatic mode when the rain sensor 173 on the motorcycle 10 detects rain. The first method involves the rider operating the shift mode switch 1811 while riding the motorcycle 10, issuing a shift mode switching command. The shift controller 191 then enters either automatic or manual mode according to the shift mode switching command. The second scenario: When the driver starts the motorcycle 10 or is riding, if the rain sensor 173 detects rainwater and the driver does not switch gears or perform a gear shifting operation, the electronic control unit 192 receives the rain detection signal from the rain sensor 173 and sends a gear shifting mode switching command to the gear shift controller 191 to enter automatic gear shifting mode. If the motorcycle 10 is in manual gear shifting mode, and the rain sensor 173 detects rainwater but the driver is performing a gear shifting operation, the electronic control unit 192 receives the signal but does not send a control command to the gear shift sensor. It enters automatic gear shifting mode when the driver operates the gear shifting mode switch 1811 to switch to automatic gear shifting mode.

[0035] This application provides a control method for a motorcycle 10, which can control the motorcycle 10 provided in the embodiments of this application.

[0046] Step S303: Motorcycle 10 is in manual shift mode.
