Description

TECHNICAL FIELD

[0002] With the rapid development of the electric two-wheeler industry and the increasing demand of consumers for intelligence and personalization, the performance and reliability of the central control system as the core control unit of the vehicle directly affect the user experience.

[0003] Currently, the electric two-wheeler controls other functional modules through the central control system. The functional modules in the electric two-wheeler and the central control system are usually connected in a discrete design. For example, when the central control system supplies power externally, high-voltage electricity is converted into the voltage required by different modules through multiple independent converters. After conversion, different modules are supplied with power. In this implementation structure, the number of converters is proportional to the modules to be powered, resulting in low power supply efficiency and high cost in the structure of the electric two-wheeler. For another example, all functional modules in the electric two-wheeler are connected to the central control system. However, some functional modules are far away from the central control system, resulting in long connection lines between the central control system and the functional modules, which increases the cost of the electric two-wheeler.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] With the rapid development of the electric vehicle industry and the increasing diversification of consumer demands, electric two-wheelers, as an important means of short-distance travel, are seeing a growing emphasis on intelligent and personalized features. The advantages of the central control system in electric two-wheelers lie in its relatively simple structure, low cost, and ability to meet basic vehicle control needs. While it achieves basic control and management of the vehicle to a certain extent, its design is still based on traditional two-wheelers. With the continuous advancement of electric vehicle technology and the increasing diversification of consumer demands, its functionality and flexible expansion still have many shortcomings.

[0048] As the communication mechanism and mode of the central control system are unreasonable, the system communication speed is slow, the parameter updating and reaction speed are slow, and the vehicle state cannot be quickly understood or convenient operation cannot be performed. At the same time, the operation interface is not friendly, which causes the user to feel inconvenient in the use process; the central control system mostly adopts a closed architecture design, and has few or no reserved expansion interfaces, so it is difficult to realize interconnection and intercommunication with other vehicle-mounted devices, which limits the function expansion and upgrade space of the central control system and cannot meet the development trend of future vehicle intelligentization and networking; although the central control system has certain advantages in cost, with the increase of intelligent functions, the cost also rises, which affects the market competitiveness of the product; and with the improvement of the networking degree of the electric two-wheeled vehicle, the safety problem of the central control system is increasingly prominent. The existing system has deficiencies in data encryption, identity authentication, access control and the like, and is easy to be attacked by hackers and subject to data leakage and other security threats.

[0049] Based on this, the application provides an electric two-wheeled vehicle system and an electric two-wheeled vehicle to solve the above problems.

[0050] The technical solutions of the application and how the technical solutions of the application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the application will be described below with reference to the drawings.

[0051] Figure 1 The electric two-wheeled vehicle system provided by the application has the structure as shown in Figure 1 The electric two-wheeled vehicle system includes:

[0052] The first module includes a first control module, and the second module includes a second control module, and the first control module is connected with the second control module.

[0053] The first module includes a plurality of first components, the first control module is connected with the plurality of first components, the distance between the plurality of first components and the first control module is less than the distance between the corresponding first component and the second control module, and the first control module is used to control the plurality of first components to run.

[0054] The second module includes a plurality of second components, the plurality of second components are connected with the second control module, the distance between the plurality of second components and the second control module is less than the distance between the corresponding second component and the first control module, and the second control module is used to control the plurality of second components to run.

[0055] The second module comprises a power supply unit, the first control module comprises a power conversion module, the power conversion module is connected with the power supply unit, and the power conversion module is configured to convert the input voltage of the power supply unit into at least two voltages with different values, the at least two voltages with different values are used to supply power to the corresponding at least two first components, and the at least two voltages with different values are less than the input voltage.

[0056] It can be understood that, Figure 1 Two first components and two second components are shown in the figure, but in other embodiments, there can be other numbers of first components and second components, which are not specifically limited here.

[0057] In some embodiments, the first control module is located at the front of the electric two-wheeled vehicle, and the first components can include a communication module, a speaker component, a light component, a sound sensor component, a screen display component, etc., which are not specifically limited here.

[0058] The one component can further include a plurality of different types of devices, such as a turn signal, a high / low beam light, a projection light, an atmosphere light, etc., and the screen display component can include a segment code screen and a liquid crystal display screen. Different types of devices in different components are also connected with the first control module.

[0059] In some embodiments, the first control module can be a central control, which is integrated with Bluetooth, power supply, wireless, etc., and can control the first components to realize related functions.

[0060] In some embodiments, the second control module is located at the tail of the electric two-wheeled vehicle, and the second components can include a gear component, a motor component, a charger component, etc., which are not specifically limited here.

[0061] The second control module can be a motor driver or a controller or a car center.

[0062] The first control module and the second control module can be connected by wire or wirelessly, such as in an embodiment, the first control module and the second control module are connected through an RS485 (a commonly used serial communication standard) interface.

[0063] In some embodiments, the first components are respectively connected to the first control modules, the second components are respectively connected to the second control modules, and the distance between the first components and the first control modules is less than the distance between the first components and the second control modules, and the distance between the second components and the second control modules is less than the distance between the second components and the first control modules, so that different components are connected to the control modules with shorter distances, avoiding the problem of long connection lines between components and a single control module, and reducing the length of the connection lines between different components and control modules by connecting the components of different control modules according to the paths between the two control modules.

[0064] Meanwhile, the first control modules are respectively connected to the first components, and the second control modules are respectively connected to the second components, so that the first control modules can control different first components in parallel, and the second control modules can process second components in parallel, improving the transmission distance of control data of the controlled components and the efficiency of component control.

[0065] In some embodiments, the second module further includes a power supply unit, which can be a power storage device, for power supply, the first control module includes a power conversion module, the power control module is connected to the power supply module, the power supply module can supply power to the power conversion module, and the power conversion module can convert the voltage of the power supply provided by the power supply module into multiple voltages with different values, thereby supplying power to the first components.

[0066] In some embodiments, different first components that require power supply may require different voltages, and the voltage value output by the power supply module is too large to directly supply power to the first components, and cannot meet the power supply voltage requirement of different values of the first components. Therefore, the power conversion module can convert the voltage of the power supply unit into other voltages.

[0067] As in some embodiments, the voltages required by the turn signal, high beam and low beam in the light component, and the liquid crystal display and speaker component in the screen display component are 12V (volts), and the voltages required by the projection lamp, atmosphere lamp in the light component, and segment code screen in the screen display component are 5V. Therefore, the power conversion module needs to convert the voltage output by the power supply unit into the voltage required by different components, thereby supplying power to the first components.

[0068] In some embodiments, the high-value voltage output by the power conversion module can be used to drive the first components, and the low-value voltage output by the power conversion module can be used to control the first components, such as 12V voltage for controlling and driving the turn signal, high beam and low beam, and 5V voltage for controlling the operation of the projection lamp, atmosphere lamp and segment code screen.

[0069] In some embodiments, as shown in Figure 2 The power conversion module outputs two different values of voltage, and the two different values of power are a first voltage and a second voltage, the power conversion module comprises a first voltage conversion unit, a second voltage conversion unit and a third voltage conversion unit, the first voltage conversion unit is connected with the power supply unit, the second voltage conversion unit is connected with the first voltage conversion unit, and the third voltage conversion unit is connected with the first voltage conversion unit.

[0070] The first voltage conversion unit is connected with the power supply unit, and is used for converting the voltage output by the power supply unit into an intermediate voltage; the intermediate voltage is smaller than the output voltage.

[0071] The second voltage conversion unit is connected with the first voltage conversion unit, and is used for receiving the intermediate voltage output by the first voltage conversion unit and converting the intermediate voltage into the first voltage, and the second voltage conversion unit is also used for providing the first voltage to at least one first component; the first voltage is smaller than the intermediate voltage.

[0072] The third voltage conversion unit is connected with the first voltage conversion unit, and is used for receiving the intermediate voltage output by the first voltage conversion unit and converting the intermediate voltage into the second voltage, and the third voltage conversion unit is also used for providing the second voltage to at least one first component; the second voltage is smaller than the first voltage.

[0073] It can be understood that the power conversion module can also output three or four different values of voltage, and by connecting a plurality of power supply units with the second power supply unit, the intermediate voltage can be converted into a voltage with a required value.

[0074] In some embodiments, the power supply unit can be a DCDC (direct current-direct current) power supply, and by the DCDC mode, the first power conversion module can convert the power output by the power supply module into an intermediate voltage, which is smaller than the voltage output by the power supply module, and then the second voltage conversion unit and the third power conversion unit further convert the intermediate voltage into a voltage with a smaller value, so that the first voltage and the second voltage can be obtained.

[0075] In some embodiments, by the intermediate voltage, the cost of the power conversion module can be reduced, if the voltage output by the power supply unit is directly converted into the first voltage and the second voltage, the voltage output by the power supply unit is relatively large, and high-power devices are required for voltage conversion, and the cost of the high-power devices is relatively high, and by setting the first power supply module, only the first power supply module requires high-power devices, and since the value of the intermediate voltage has been reduced, the second power supply module and the third power supply module do not require high-power devices, so that the cost of the power conversion module can be reduced.

[0076] As in an embodiment, the power supply unit inputs a voltage of 72V, the first voltage conversion unit converts the voltage of 72V into a voltage of 24V, which is the intermediate voltage, and the intermediate voltage is converted into 12V and 5V through the second voltage conversion unit and the third voltage conversion unit, which correspond to the first voltage and the second voltage.

[0077] Of course, it can be understood that the above-mentioned input voltage of the power supply unit is 72V, which is exemplary, and in other embodiments, the input voltage can also be other numerical values, such as 48V, 60V, etc., which are not specifically limited here; the intermediate voltage is 24V, which is also exemplary, and can also be other numerical values of the intermediate voltage, which is not specifically limited here; the first voltage and the second voltage are 12V and 5V, which are also exemplary, and can also be other numerical values of the first voltage and the second voltage, which are not specifically limited here.

[0078] According to the voltage values required by different components, different numerical values of the voltage output by the voltage conversion module can be used to power different components.

[0079] In some embodiments, to further ensure the reliability of the power conversion module, the first voltage conversion unit, the second voltage conversion unit and the third voltage conversion unit can be provided with voltage stabilizing circuits and protection circuits, so as to provide overvoltage protection and overcurrent protection for the first voltage conversion unit, the second voltage conversion unit and the third voltage conversion unit, improve the reliability of the power conversion module, and ensure the output of the corresponding numerical value of the voltage.

[0080] In some embodiments, the plurality of first components includes a loudspeaker assembly, the loudspeaker assembly includes a sound driving unit and a sound playing unit, and the first control module includes a sound control unit; the sound control unit is configured to receive a sound playing trigger signal and generate a corresponding loudspeaker control signal based on the sound playing trigger signal; the sound playing trigger signal is any one of an overspeed alarm sound playing trigger signal, an iron horn sound playing trigger signal, and a chord sound playing trigger signal; the sound driving unit is connected to the sound control unit and is configured to drive and amplify a corresponding sound signal according to the loudspeaker control signal to obtain a processed sound signal; and the sound playing unit is connected to the sound driving unit and is configured to play the processed sound signal.

[0081] The loudspeaker assembly can be a horn, and the sound playing trigger signal received by the sound control unit can be triggered by a user on the electric two-wheeled vehicle or generated in a specific scene, such as generating an iron horn sound playing trigger signal by pressing a key, generating a chord sound playing trigger signal by selecting a function in the screen display assembly, or generating an overspeed alarm sound playing trigger signal when the electric two-wheeled vehicle is overspeed, which is not specifically limited here.

[0082] As Figure 3As shown, the sound playback trigger signal enters the sound control unit, is processed by the sound control unit to generate a speaker control signal, and outputs the speaker control signal to the speaker assembly. The sound drive unit drives and amplifies the corresponding sound signal according to the speaker control signal to obtain the processed sound signal. The sound drive unit sends the processed sound signal to the sound drive unit, thereby playing the sound through the sound drive unit.

[0083] Understandably, different sound playback trigger signals correspond to different speaker control signals, thus enabling the playback of multiple different sounds through a single speaker component.

[0084] In some embodiments, such as Figure 4 The diagram also shows a schematic of a sound driver unit, which can be an NS4100B (a microcontroller). The sound signal (SPK+) corresponding to the sound control unit enters the sound driver unit through INP+ (positive input pin). The sound driver unit's INN- (negative input pin) is grounded (GND) through resistor R6 and capacitor C8. The sound driver unit's BYPASS (bypass pin) is grounded through capacitor C6. The sound driver unit's EP (control pin) is connected to a power input of 5V via resistor R1. The sound driver unit's CTRL (register) is connected to EnSleep (low-power mode) via resistor R2, and resistor R2 is connected to resistor R1. The sound driver unit's GND is grounded. The sound driver unit's VDD (power pin) is connected to a 12V power supply. The positive portion (VOI_P) of the processed sound signal output from the sound driver unit's VOP+ (positive output pin) and the negative portion (VOI_N) of the processed sound signal output from the VON- (negative output pin) enter the... Figure 5 The sound playback unit shown plays sound.

[0085] In the embodiments of this application, Figure 4 The capacitors and resistors in the sound driver unit can be used to filter and smooth the input power supply, allowing the sound driver unit to process it better, while the resistors can be used for voltage division and current limiting, improving the reliability of the sound driver unit.

[0086] In some embodiments, the plurality of first components include a light assembly, which includes left and right turn signals, high and low beam lights, side marker lights, taillights, lock lights, hazard lights, etc., without specific limitations.

[0087] The first control module includes a lighting control unit, which is used to control the lighting components to emit light.

[0088] In some embodiments, the light control unit can directly control different lights in the light assembly to emit different light, such as in an emergency situation, a control signal for emitting double flash light is sent to the light control unit through the button to control the light assembly to emit double flash light.

[0089] In some embodiments, the light assembly is directly connected to the electric two-wheeled vehicle through the first direct terminal, and is connected to the first control module. The first direct terminal connected to the light assembly is a light control interface. The first control module can directly control the light assembly to emit light through the first direct terminal. In other embodiments, a micro control device or a color light integrated circuit can be used to control the light assembly.

[0090] In some embodiments, the sound control unit is connected to the light control unit to send a speaker control signal to the light control unit. The light control unit is further configured to control the light assembly to emit light according to the speaker control signal.

[0091] When the sound control unit sends a speaker control signal, the light control unit can also receive the speaker control signal and control the light assembly to emit light according to the speaker control signal.

[0092] It can be understood that different speaker control signals can correspond to different control signals of the light assembly. For example, when the speaker control signal is a signal corresponding to the sound playing trigger signal of the iron horn, the corresponding control signal of the light control unit for the light assembly is a control signal for controlling the high beam and low beam to emit light. Of course, this is an example. In other embodiments, different speaker control signals are input to the light control unit, and the light control unit controls different lights in the light assembly to emit light. That is, the speaker control signal and the control signal of the light assembly can correspond one-to-one, so that when the speaker assembly emits different horn sounds, the corresponding light assembly emits different light.

[0093] In some embodiments, the first control module is connected to the second control module. When the second component in the second module fails, the fault signal is transmitted to the first control module through the second control module, so that the sound control unit and the light control unit in the first control module can control the speaker assembly to emit sound and the light assembly to emit light according to the fault signal.

[0094] For example, in an embodiment, the battery and the motor in the second component fail, and the fault signal is transmitted to the first control module through the second control module. The light control unit in the first control module receives the fault signal and controls the vehicle ambient light and the double flash warning light to automatically turn on, and the sound control unit controls the speaker assembly to emit sound for alarm.

[0095] In some embodiments, the plurality of first components further comprise a sound sensor component connected with the light control unit, for receiving the processed sound signal played by the sound playing unit and generating a light control signal; the light control unit is further configured to receive the light control signal and control the light component to emit light.

[0096] The sound sensor component can receive the sound played by the speaker component and generate a light control signal, so that the sound sensor component can send the light control signal to the light component, and the light component emits light, realizing the cooperation of the speaker component and the light component, such as emitting a specific light under a specific sound.

[0097] In other embodiments, the sound sensor component can obtain the sound in the driving environment of the electric two-wheeled vehicle, and the sound sensor can generate a warning signal according to the received sound, such as automatically generating a warning signal after receiving the sound of a truck or a large vehicle, or sending the received sound signal to the first control unit, and the first control unit generates a warning signal.

[0098] The warning signal can also enter the light control unit and the sound control unit in the first control module, so as to control the light component to emit light and control the speaker component to emit sound, and the warning signal can be warned through the speaker component and the light control component.

[0099] In some embodiments, the plurality of first components further comprise a screen display component; the screen display component is connected with the first control module through a first one-wire interface, the first one-wire interface is an interface integrating sending function and receiving function, and the first one-wire interface adopts serial universal asynchronous receiver transmitter (UART) communication protocol.

[0100] In some embodiments, the first one-wire interface can be an upgraded one-wire interface, and the first one-wire interface adopts serial universal asynchronous receiver transmitter (UART) communication protocol.

[0101] The screen display component and the first control module are connected through the first one-wire interface, so as to improve the communication efficiency between the screen display component and the first control module.

[0102] In some embodiments, the screen display component can include various screens, such as segment code screen and liquid crystal display screen, the segment code screen can be connected with the first control module through a first one-wire interface, and the liquid crystal display screen can also be connected with the first control module through a first one-wire interface.

[0103] In some embodiments, the segment code screen and the liquid crystal display screen can be simultaneously connected in double display mode through the RS485 interface and the first one-wire interface.

[0104] In some embodiments, the screen display component is further connected with the sound control unit, and the screen display component is further configured to store audio as a sound signal, and the sound control unit is further configured to receive the sound signal sent by the screen display component.

[0105] In some embodiments, the sound signal is stored in the screen display component, so that the utilization of the storage space of the screen display component can be improved.

[0106] In some embodiments, the screen display component is connected with the sound control unit through the first control unit, and when the sound driving unit in the loudspeaker component determines the loudspeaker control signal, the screen display component can be accessed to obtain the corresponding sound signal and perform driving amplification processing, so that the sound playing unit can play the processed sound signal.

[0107] In some embodiments, the screen display component includes a light sensor, a segment code screen, and a liquid crystal display screen, the light sensor is connected with the segment code screen and the liquid crystal display screen, the light sensor is configured to receive a light signal, the light sensor is connected with the first control module, the light sensor is configured to receive the light signal and send the light signal to the first control module, the first control module is configured to convert the light signal into a light control signal, and the light control signal is configured to adjust the brightness of the segment code screen and the liquid crystal display screen and / or control the opening and closing and brightness of the lamp assembly.

[0108] In some embodiments, the light sensor can receive a light signal, different light signals correspond to different light intensities, the light sensor sends the light signal to the first control module, the first control module can obtain the light control signal corresponding to the light signal through the corresponding relationship between the light intensity and the light control signal, and the first control module transmits the light control signal to the segment code screen and the liquid crystal display screen, so that the segment code screen and the liquid crystal display screen can control the brightness of the segment code screen and the liquid crystal display screen according to the light control signal, thereby realizing the adaptive adjustment of the screen brightness of the segment code screen and the liquid crystal display screen.

[0109] In some embodiments, if the light signal corresponds to a high light intensity, the corresponding light control signal is to adjust the brightness of the segment code screen and the liquid crystal display screen, and if the light signal corresponds to a low light intensity, the corresponding light control signal is to adjust the brightness of the segment code screen and the liquid crystal display screen.

[0110] As in some embodiments, the segment code screen and the liquid crystal display screen internally store a screen adjustment program, and when receiving a light control signal, the screen brightness of the segment code screen and the liquid crystal display screen can be automatically adjusted according to the control program corresponding to the light control signal. For example, when the light control signal indicates to dim the screen, the screen brightness of the segment code screen and the liquid crystal display screen is reduced.

For example, when the light control signal indicates to modify the screen font to red, the segment code screen and the liquid crystal display screen modify the font to red. Here, no specific limitation is made. Through the light control signal, the segment code screen and the liquid crystal display screen can be adjusted.

[0111] In some embodiments, the first control module can also control the opening and closing and brightness of the lamp assembly by sending a light control signal to the lamp assembly. For example, when the light signal corresponds to a high light intensity, the corresponding light control signal entering the lamp assembly reduces the brightness of the lamp in the lamp assembly or turns off the light in the lamp assembly. For example, when the light signal corresponds to a low light intensity, the corresponding light control signal entering the lamp assembly brightens the brightness of the lamp in the lamp assembly or turns on the light in the lamp assembly.

[0112] For example, in some embodiments, the lamp control unit has a light adjustment program, and when receiving a light control signal, the brightness of the lamp in the lamp assembly or the opening / closing of the lamp in the lamp assembly can be adjusted according to the control program corresponding to the light control signal.

[0113] In some embodiments, the light control signal can enter the lamp control unit, and the lamp control unit controls the brightness and opening / closing of the lamp in the lamp assembly according to the light control signal.

The insulating unit covers the functional unit, and the insulating unit is provided with a plurality of heat dissipation holes filled with silica gel.

[0114] In some embodiments, the functional unit in the power conversion module is provided with a large number of components for voltage conversion, and the heat is high. Therefore, heat dissipation is needed to improve the reliability of the functional module.

For example, in a distributed connection, the first control module is connected to component A, and an adapter is arranged in the line connecting the first control module and component A through the line connecting the first control module and component A, and component B is connected through the adapter. In this process, the connection cost of component B is increased, and component A and component B share a section of line, so the first control module cannot control component A and component B at the same time. The control signal of the first control module for controlling component B needs to pass through the line between component A and the first control module, which reduces the speed of data transmission.

[0121] In some embodiments, the plurality of first direct terminals can also have a reserved port, which is not connected to the first components at present. After the first components are added subsequently, the port for connecting the first control module and the first components can be provided.

[0124] In the embodiments of the present application, the direct terminal connection component and the control module increase the expandability and upgrade space of the electric two-wheeled vehicle system, and the direct terminal connection also saves the assembly time and reduces the production difficulty.

[0125] In other embodiments, a TVS (Transient Voltage Suppressor, a component that protects electrical and electronic equipment from transient voltage damage) can be arranged on the direct terminal to further protect the direct terminal from overvoltage and improve the reliability of the component.

[0126] In some embodiments, the first direct terminal includes a first power terminal and a first function terminal; the first control module supplies power to the first component through the first power terminal; and the first function terminal includes one or more of a first one-wire pass-through interface, an RS485 interface, a CAN (Controller Area Network) interface, an NFC (Near Field Communication) interface, a baseband interface, and a positioning interface.

[0131] In some embodiments, the first control module and the second control module are connected through a communication interface, and the communication interface comprises one of an RS485 interface and a CAN interface.
