Description

Technical Field

[0001] This application relates to the field of transportation technology, specifically to a method for controlling the driving force of a two-wheeled vehicle and an electric two-wheeled vehicle. Background Technology

[0002] In recent years, the popularity of electric two-wheeled vehicles has been increasing, and the number of urban and rural residents using electric two-wheeled vehicles has been increasing year by year.

[0003] Some existing electric two-wheelers are equipped with an anti-slip function. This means that when the driver leaves the seat during vehicle startup, the throttle control is disabled to protect the driver's safety and prevent accidental loss of control. However, with this feature, the throttle control cannot be used properly when the electric two-wheeler needs assistance pushing, such as when pushing uphill. Since the driver is not on the seat and the throttle control is disabled, the electric two-wheeler cannot move forward even when the throttle is turned. In this situation, the electric two-wheeler can only be pushed manually, resulting in a poor user experience. Summary of the Invention

[0004] In order to overcome the problems existing in the prior art, the main purpose of this application is to provide a two-wheeled vehicle driving force control method that can facilitate the movement and braking of vehicles in narrow spaces or on sloping roads.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] This application provides a method for controlling the driving force of a two-wheeled vehicle. The two-wheeled vehicle includes a power source and a control unit connected to the power source. The control method is applied to the control unit, and the two-wheeled vehicle includes a first mode and a second mode. The control method includes:

[0007] When the two-wheeled vehicle is activated, confirm whether the two-wheeled vehicle is activated in the first mode or the second mode;

[0008] When it is confirmed that the two-wheeled vehicle is in the first mode, the power source is controlled to provide assistance according to the driver's pushing intention;

[0009] When it is confirmed that the two-wheeled vehicle is in the second mode, the power source is controlled to provide braking force according to the driver's pushing intention.

[0010] In some embodiments, if the two-wheeled vehicle is a two-wheeled electric vehicle, the power source includes at least an electric motor;

[0011] When it is confirmed that the two-wheeled vehicle is in the first mode, controlling the power source to provide assistance according to the driver's pushing intention includes:

[0012] Determine whether the wheel speed of the two-wheeled vehicle is greater than zero;

[0013] When it is confirmed that the wheel speed of the two-wheeled vehicle is greater than zero, the motor of the two-wheeled vehicle is controlled to output power, and the direction of the power is the same as the rotation direction of the wheels and / or the motor; wherein, the power is less than the driving force required for the two-wheeled vehicle to drive automatically.

[0014] In some embodiments, after the step of controlling the motor output power of the two-wheeled vehicle, the method further includes:

[0015] Determine whether the two-wheeled vehicle receives a braking signal or whether the wheel speed of the two-wheeled vehicle is equal to zero within a preset time range;

[0016] When the two-wheeled vehicle receives a braking signal or when the wheel speed of the two-wheeled vehicle is equal to zero within a preset time range, the motor of the two-wheeled vehicle is controlled to stop outputting power.

[0017] In some embodiments, when it is confirmed that the two-wheeled vehicle is in the second driving mode, controlling the power source to provide braking force according to the driver's pushing intention includes:

[0018] Determine whether the two-wheeled vehicle is on a slope in a first direction, wherein the first direction is the direction of travel of the two-wheeled vehicle;

[0019] Once it is confirmed that the two-wheeled vehicle is on a slope in the first direction, it is further determined whether the two-wheeled vehicle is moving in the second direction, wherein the second direction is opposite to the first direction;

[0020] When it is confirmed that the two-wheeled vehicle is moving in the second direction and the two-wheeled vehicle has not received an acceleration signal, the power source of the two-wheeled vehicle is controlled to output braking force in the first direction.

[0021] The two-wheeled vehicle is equipped with a detection device, which can determine whether the two-wheeled vehicle is on a slope in the first direction.

[0022] In some embodiments, if the two-wheeled vehicle is an electric two-wheeled vehicle, the power source includes at least an electric motor;

[0023] When it is confirmed that the two-wheeled vehicle is moving in the second direction and the two-wheeled vehicle has not received an acceleration signal, controlling the power source of the two-wheeled vehicle to output braking force along the first direction includes: controlling the output torque of the motor of the two-wheeled vehicle, wherein the magnitude of the output torque of the motor is related to the slope of the ramp road surface.

[0024] In some embodiments, the first mode and the second mode are turned on or off by a fixed switch, a handlebar instrument combination switch or a smart terminal APP;

[0025] The two-wheeled vehicle issues a prompt message when the first mode or the second mode is turned on or off.

[0026] Accordingly, this application also provides an electric two-wheeled vehicle, which includes a motor for providing power and a control unit connected to the motor. The electric two-wheeled vehicle includes a first mode, and is equipped with a first detection unit for detecting wheel speed. The first detection unit is connected to the control unit. When the electric two-wheeled vehicle is in the first mode, if the first detection unit detects wheel speed, the control unit controls the motor to provide power; and / or

[0027] The electric two-wheeled vehicle also includes a second mode. When the electric two-wheeled vehicle is in the second mode, if the electric two-wheeled vehicle is on a slope in the first direction, and the electric two-wheeled vehicle moves in the second direction and does not receive an acceleration signal, the control unit controls the motor to provide braking force in the first direction, where the first direction is the direction of travel of the electric two-wheeled vehicle, and the second direction is opposite to the first direction.

[0028] In some embodiments, the direction of the power is the same as the rotation direction of the wheels and / or the motor, and the power is less than the driving force required for the electric two-wheeler to drive automatically;

[0029] If the first detection unit does not detect wheel speed or brake signal within a preset time range, the control unit controls the motor to stop outputting power.

[0030] In some embodiments, the electric two-wheeler is further provided with a second detection unit, which is used to detect whether the electric two-wheeler is on a sloping road surface in the first direction;

[0031] Wherein, if the electric two-wheeled vehicle is on a slope in the first direction, and the electric two-wheeled vehicle moves in the second direction, and the second detection unit does not receive an acceleration signal, the control unit controls the motor to provide braking force along the first direction, including: the control unit controls the motor output torque of the electric two-wheeled vehicle, wherein the magnitude of the torque output by the motor is related to the slope of the slope.

[0032] In some embodiments, the first mode and the second mode are turned on or off by a fixed switch, a handlebar instrument combination switch or a smart terminal APP;

[0033] When the first mode or the second mode is turned on or off, the electric two-wheeler issues a prompt message.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0041] When two-wheeled vehicles are going uphill or downhill, such as when entering or exiting an underground parking lot ramp, they are prone to rolling backwards, posing a safety hazard. To facilitate the entry and exit of two-wheeled vehicles from underground parking lot ramps, this application discloses a method for controlling the driving force of two-wheeled vehicles. This method assists in controlling the driving force of the two-wheeled vehicles when going uphill or downhill, preventing them from rolling backwards while queuing. (Refer to...) Figure 1 As shown, Figure 1 This is a flowchart of a method for controlling the driving force of a two-wheeled vehicle according to an embodiment of this application. The two-wheeled vehicle includes a power source and a control unit connected to the power source. The method for controlling the driving force of the two-wheeled vehicle is applied to the control unit and includes the following steps:

[0042] S11, Start the two-wheeled vehicle.

[0043] S12. Confirm whether the two-wheeled vehicle is in the first or second mode.

[0044] Specifically, if the first or second mode is activated, the vehicle will provide corresponding prompts via indicator lights or voice commands.

[0045] S13. When it is confirmed that the two-wheeled vehicle is in the first mode, control the power source to provide assistance according to the driver's pushing intention.

[0046] S14. When it is confirmed that the two-wheeled vehicle is in the second mode, control the power source to provide braking force according to the driver's pushing intention.

[0047] Furthermore, if the first mode of the two-wheeled vehicle is turned off, the two-wheeled vehicle will stop outputting power assist; if the second mode of the two-wheeled vehicle is turned off, the two-wheeled vehicle will stop outputting braking force.

[0048] Reference Figure 2 As shown, Figure 2 This is a flowchart illustrating the control assist output provided in an embodiment of this application. The control assist output specifically includes:

[0049] S101, Start the two-wheeled vehicle.

[0050] S102, Activate the first mode of the two-wheeled vehicle.

[0051] Specifically, the first mode can be activated directly via a fixed switch on the handlebars, or via a combination switch on the handlebars and instrument panel. For example, you can use the up, down, left, and right buttons on the handlebars and then confirm the activation on the instrument panel. Alternatively, you can activate the first mode via an app on a device such as a mobile phone or tablet.

[0052] Furthermore, when the first mode function is activated, the power steering activation light is displayed on the vehicle's instrument panel, and a first prompt sound is emitted to remind the user that the vehicle's first mode has been activated.

[0053] S103. Determine whether the two-wheeled vehicle has activated the first mode. If the determination result is yes, proceed to step S104. If the determination result is no, proceed to step S108.

[0054] S104. Determine whether the wheel speed of the two-wheeled vehicle is greater than zero. If the result is yes, proceed to step S105. If the result is no, proceed to step S108.

[0055] S105. Control the motor output power of the two-wheeled vehicle, the direction of which is the same as the rotation direction of the wheels and / or the motor.

[0056] Specifically, if the two-wheeled vehicle is electric, the power source includes at least a motor. When the electric two-wheeled vehicle is in its first mode, the direction of the motor's output power can be the same as the direction of wheel rotation, the same as the direction of motor rotation, or both. Furthermore, the power output by the vehicle's motor must be less than the driving force required for the two-wheeled vehicle to move automatically; that is, the power output by the motor should be insufficient to make the two-wheeled vehicle move automatically, to prevent the vehicle from moving on its own under the influence of this power, which could pose a safety hazard.

[0057] S106. Determine whether the two-wheeled vehicle has received a braking signal or whether the wheel speed of the two-wheeled vehicle is equal to zero within a preset time range. If the determination result is yes, that is, the two-wheeled vehicle has received a braking signal or the wheel speed of the two-wheeled vehicle is equal to zero within a preset time range, proceed to step S108. If the determination result is no, that is, it is not one of the above two situations, return to step S105.

[0058] S107, the first mode for turning off two-wheeled vehicles.

[0059] Specifically, the first mode can be turned off directly via a fixed switch on the handlebars, or via a combination switch on the handlebars and instrument panel. For example, you can press the up, down, left, and right buttons on the handlebars and then confirm the button on the instrument panel to turn off the first mode. Alternatively, you can turn off the first mode via an app on a device such as a mobile phone or tablet.

[0060] Further, when the first mode is turned off, the power steering on indicator light on the vehicle's instrument panel turns off accordingly. At the same time, the vehicle emits a second warning sound to remind the user that the first mode has been turned off. The second warning sound is different from the first warning sound.

[0061] S108, Control the motor of the two-wheeled vehicle to stop outputting power.

[0062] Reference Figure 3 As shown, Figure 3This application provides a flowchart illustrating the control of braking force output in an embodiment. The control of braking force output specifically includes:

[0063] S201, Start the two-wheeled vehicle.

[0064] S202, Activate the second mode of the two-wheeled vehicle.

[0065] Specifically, the second mode can be activated directly via a fixed switch on the handlebars, or via a combination switch on the handlebars and instrument panel. For example, you can use the up, down, left, and right buttons on the handlebars and then confirm the activation on the instrument panel to control the activation of the second mode. Alternatively, you can activate the second mode via an app on a terminal (such as a mobile phone or tablet).

[0066] Furthermore, when the second mode function is activated, the vehicle's instrument panel displays the anti-rollover activation light, and a third prompt sound is emitted to remind the user that the vehicle's second mode has been activated.

[0067] S203. Determine whether the two-wheeled vehicle has activated the second mode. If the determination result is yes, proceed to step S204. If the determination result is no, proceed to step S209.

[0068] S204. Determine whether the two-wheeled vehicle is on a slope in the first direction. If the determination result is yes, proceed to step S205. If the determination result is no, proceed to step S209.

[0069] Specifically, a detection device can be installed on the two-wheeled vehicle to determine whether the two-wheeled vehicle is on a slope in the first direction. The first direction refers to the direction of travel of the two-wheeled vehicle, and the slope refers to the road surface in the direction of travel of the two-wheeled vehicle being inclined (a road with a certain slope, the degree of which can be set as needed). For example, if the two-wheeled vehicle is on the uphill or downhill side of the slope, it can be determined that the two-wheeled vehicle is on a slope in the first direction.

[0070] S205. Continue to determine whether the two-wheeled vehicle is moving in the second direction. If the determination result is yes, proceed to step S206. If the determination result is no, proceed to step S209.

[0071] The second direction refers to the direction opposite to the first direction, that is, the second direction refers to the direction opposite to the direction of travel of the two-wheeled vehicle.

[0072] S206. Continue to determine whether the two-wheeled vehicle receives an acceleration signal. If the determination result is no, proceed to step S207. If the determination result is yes, proceed to step S209.

[0073] S207, Control the power source output of the two-wheeled vehicle to provide braking force in the first direction.

[0074] Specifically, the motor of the two-wheeled vehicle is controlled to enter a zero-speed mode, that is, the motor of the vehicle is controlled to output torque only and not speed, and the magnitude of the torque output by the motor is related to the slope of the road surface. At this time, the magnitude of the torque output by the motor should be able to ensure that the vehicle does not slip on a certain slope when there is no external pushing force.

[0075] S208, the second mode for turning off two-wheeled vehicles.

[0076] Specifically, the second mode can be turned off directly via a fixed switch on the handlebars, or via a combination switch on the handlebars and instrument panel. For example, you can press the up, down, left, and right buttons on the handlebars and then confirm the button on the instrument panel to turn off the second mode. Alternatively, you can turn off the second mode via an app on a device such as a mobile phone or tablet.

[0077] Furthermore, when the second mode function is turned off, the anti-rollover indicator light on the vehicle's instrument panel will turn off accordingly, and a fourth warning sound will be emitted to remind the user that the vehicle's second mode has been activated. The fourth warning sound is different from the third warning sound.

[0078] S209. Control the motor of the two-wheeled vehicle to stop outputting braking force.

[0079] In existing electric two-wheelers, braking force is typically provided by a brake and power output is controlled by a throttle. However, providing braking force via a brake requires constant control of the brake, which is complex and poses safety hazards. Similarly, controlling power output via a throttle requires constant control of the throttle, which is also complex and poses safety hazards. Furthermore, in existing electric two-wheelers, when the driver is not on the vehicle, it is difficult for the driver to operate the throttle, meaning it is impossible to maintain constant control of the throttle. Consequently, the vehicle may not provide automatic braking force, requiring the driver to keep the brake closed and manually brake the vehicle, which is also complex and poses safety hazards.

[0080] The control method of this application can control the vehicle to output power assistance regardless of whether the driver is in the vehicle, so as to facilitate the movement of the vehicle in narrow spaces or on sloping roads. It can also control the vehicle to output braking force, so as to facilitate braking of the vehicle in narrow spaces or on sloping roads.

[0081] This application effectively utilizes the characteristics of automatic vehicle speed detection by the motor to provide assistance to the vehicle. It is simple to operate and highly safe. At the same time, it effectively utilizes the characteristics of the motor to provide a certain amount of power to the vehicle without the need for brakes. It is simple to operate and highly safe.

[0082] Correspondingly, embodiments of this application also disclose an electric two-wheeled vehicle, which includes a motor for providing power and a control unit connected to the motor, the control unit being capable of executing the control method described in any of the above embodiments.

[0083] Specifically, the electric two-wheeler includes a first mode and a second mode. The electric two-wheeler is equipped with a first detection unit and a second detection unit, both connected to a control unit. The first detection unit detects the wheel speed and braking signal of the electric two-wheeler, while the second detection unit detects whether the electric two-wheeler is on a slope in the first direction. In the first mode, if the first detection unit detects the wheel speed, the control unit controls the motor to provide power; if the first detection unit detects a braking signal or does not detect wheel speed within a preset time range, the control unit controls the motor to stop outputting power. In the second mode, if the electric two-wheeler is on a slope in the first direction and is moving in the second direction, and the second detection unit does not detect an acceleration signal, the control unit controls the motor to provide braking force in the first direction. The first direction is the direction of travel of the electric two-wheeler, and the second direction is opposite to the first direction.

[0084] Furthermore, the direction of power provided by the motor is the same as the direction of rotation of the wheels or the motor, and this power is less than the driving force required for the electric two-wheeler to move automatically. Specifically, the control unit controls the motor to provide braking force by controlling the output torque of the electric two-wheeler's motor, the magnitude of which is related to the gradient of the slope.

[0085] Furthermore, the second mode can be turned off directly via a fixed switch on the handlebars, or via a combination switch on the handlebars and instrument panel. For example, you can press the up, down, left, and right buttons on the handlebars and then confirm the button on the instrument panel to turn off the second mode. Alternatively, you can turn off the second mode via an app on a terminal (such as a mobile phone or tablet).

[0086] The two-wheeled vehicle mentioned above can be an electric two-wheeled vehicle or a fuel-powered two-wheeled vehicle. The fuel-powered two-wheeled vehicle is equipped with a motor, and the motor in the electric or fuel-powered two-wheeled vehicle can provide assistance or braking force according to the driver's pushing intention.

[0087] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
