[0029] Example 1

[0030] Figure 1A flowchart of an electric vehicle control method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of controlling multi-wheeled electric vehicles, such as electric two-wheeled vehicles. The method can be executed by an electric vehicle control device, which can be implemented in the form of hardware and / or software. The electric vehicle control device can be configured in an electronic device, which can be composed of two or more physical entities or one physical entity.

[0031] like Figure 1 As shown, the electric vehicle control method provided in the first embodiment of the present invention can be applied to electric vehicles and specifically includes the following steps:

[0032] S101: Acquire a current control analog signal of the electric vehicle.

[0033] In this embodiment, the user can trigger the current electric vehicle to generate a control analog signal by touching the screen, pressing, rotating, etc. For example, the acceleration analog signal can be generated by rotating the handlebar.

[0034] S102: Convert the control analog signal into a control digital signal using an analog-to-digital conversion module.

[0035] In this embodiment, a current electric vehicle may be pre-installed with an analog-to-digital conversion module, which can be used to convert a control analog signal into a control digital signal.

[0036] S103: Send the control digital signal to the control object unit through the CAN bus, so as to control the current electric vehicle through the control object unit.

[0037] In this embodiment, a CAN bus may be pre-arranged in the current electric vehicle, and a control digital signal may be sent to a control target unit, such as a motor controller unit, via the CAN bus to control the speed of the current electric vehicle via the motor controller unit.

[0038] The electric vehicle control method provided by an embodiment of the present invention obtains an analog control signal from the current electric vehicle, converts the analog control signal into a digital control signal using an analog-to-digital conversion module, and transmits the digital control signal to a control target unit via a CAN bus, thereby controlling the current electric vehicle via the control target unit. The technical solution of an embodiment of the present invention converts the analog control signal for the electric vehicle into a digital signal and then transmits the digital signal to the control target via a CAN bus. This not only achieves accurate control of the electric vehicle, improving vehicle safety and response speed, but also saves wiring harnesses and significantly reduces costs.

[0039] Optionally, the control digital signal is sent to the control object unit via the CAN bus to control the current electric vehicle via the control object unit, including: if the control digital signal includes a second control signal for controlling a second object, the second control signal is differentially transmitted to the microcontroller unit MCU in the liquid-cooled motor module via the CAN bus, wherein the second object includes the liquid-cooled motor in the liquid-cooled motor module; and the liquid-cooled motor is instructed by the MCU to execute the instruction corresponding to the second control signal to achieve control of the speed of the current electric vehicle.

[0040] Specifically, the current driving motor of the electric vehicle can be a digital liquid-cooled motor. If the control digital signal includes a digital signal for controlling the liquid-cooled motor (i.e., a second control signal for controlling the second object), the digital signal is differentially transmitted to the MCU in the liquid-cooled motor module via the CAN bus. The MCU can execute the instructions corresponding to the digital signal to control the wheel speed of the current electric vehicle. Among them, differential transmission is a signal transmission technology. Different from the traditional practice of one signal line and one ground line, differential transmission transmits signals on both lines. The two signals have the same amplitude and opposite phases. The signal receiving end determines the logical state sent by the sending end by comparing the voltage difference of the signals on the two lines.

[0041] Optionally, after the MCU instructs the liquid-cooled motor to execute the instruction corresponding to the control digital signal, it also includes: differentially transmitting the wheel speed signal of the current vehicle to the instrument display screen through the CAN bus.

[0042] Specifically, the wheel speed signal of the current vehicle can be differentially transmitted to the instrument display screen via the CAN bus, so that the wheel speed can be displayed on the instrument display screen.

[0043] Optionally, the CAN bus includes: a power line, a ground line, a low-order data line CAN-L and a high-order data line CAN-H.

[0044] Specifically, traditional vehicle front and rear lighting controls and controllers are typically independent wiring units with numerous leads, numerous plug-ins, and a relatively complex design. The main wiring harness typically has 16 to 18 wires. However, this solution enables vehicle control via a four-wire CAN bus. This eliminates 12 to 14 wires, significantly reducing costs and lowering the risk of failures caused by poor contact between plug-ins and wiring harnesses.

[0045] Example 2

[0046] Figure 2 This is a flow chart of a method for controlling an electric vehicle provided in the second embodiment of the present invention. The technical solution of the embodiment of the present invention is further optimized on the basis of the above-mentioned optional technical solutions, and provides a specific method for controlling a multi-wheeled electric vehicle.

[0047] Optionally, the control analog signal includes a handlebar control analog signal; wherein, using an analog-to-digital conversion module to convert the control analog signal into a control digital signal includes: using the analog-to-digital conversion module built into the front electronic control unit FECU of the current electric vehicle to convert the handlebar control analog signal into a control digital signal.

[0048] Optionally, the FECU further has a built-in first metal oxide semiconductor field effect transistor MOSFET;

[0049] Among them, after the control analog signal is converted into a control digital signal by using the analog-to-digital conversion module, it also includes: if the control digital signal includes a first control signal for controlling a first object, then through the first MOSFET in the FECU, the first object of the current electric vehicle is controlled according to the first control signal, wherein the first object includes a mobile phone charging device, a voice speaker, a headlight, a horn and an electric vehicle lock.

[0050] Optionally, the current electric vehicle is equipped with a rear electronic control unit RECU; the RECU has a built-in second MOSFET; wherein, the control digital signal is sent to the control object unit via the CAN bus to control the current electric vehicle via the control object unit, including: if the control digital signal includes a third control signal for controlling a third object, the third control signal is differentially transmitted to the RECU via the CAN bus, wherein the third object includes a breathing light, a license plate light, a taillight and a saddle lock; and the third object in the current electric vehicle is controlled according to the third control signal through the second MOSFET in the RECU.

[0051] like Figure 2 As shown, a second embodiment of the present invention provides an electric vehicle control method, which specifically includes the following steps:

[0052] S201: Acquire a current analog signal of a handlebar control of the electric vehicle.

[0053] S202: Utilize the analog-to-digital conversion module built into the front electronic control unit (FECU) of the current electric vehicle to convert the handlebar control analog signal into a control digital signal.

[0054] Specifically, Figure 3 Figure 1 is a schematic diagram of the structure of an electric vehicle. Figure 3As shown, current electric vehicles can be equipped with a front electronic control unit (FECU). The left handlebar 101, instrument display 102, right handlebar 103, mobile phone charger 104, voice speaker 105, left headlight 106, electric vehicle lock 107, horn 108, and right headlight 109 are electrically connected to the FECU. An analog-to-digital conversion module can be pre-installed in the FECU. The FECU is used to convert analog signals into digital signals.

[0055] S203. Convert the handlebar control analog signal into a control digital signal using an analog-to-digital conversion module, wherein the control digital signal includes a first control signal for controlling a first object, a second control signal for a second object, and a third control signal for a third object.

[0056] S204 : Control a first object of the current electric vehicle according to the first control signal through the first MOSFET in the FECU.

[0057] Among them, the first objects include a mobile phone charging device, a voice speaker, a headlight, a horn and an electric vehicle lock.

[0058] Specifically, existing vehicles directly control the first object through mechanical switches, while the present invention drives the first object through signal processing and MOSFETs. Since the signal switch does not draw current, its service life can be significantly extended. The FECU can include multiple MOSFETs. Upon receiving the first control signal, these MOSFETs can drive the mobile phone charger, voice speaker, headlights, horn, and electric vehicle locks.

[0059] S205. Differentially transmit the second control signal to the microcontroller unit MCU in the liquid-cooled motor module through the CAN bus, wherein the second object includes the liquid-cooled motor in the liquid-cooled motor module; instruct the liquid-cooled motor to execute the instruction corresponding to the second control signal through the MCU to control the speed of the current electric vehicle.

[0060] Specifically, the integrated powertrain control system is subject to interference from the electromagnetic field inside the motor, which can interfere with the traditional analog signal from the handlebar, affecting vehicle riding. Digital signals are differentially transmitted to the control object via the CAN bus, effectively suppressing interference.

[0061] S206. Differentially transmit the third control signal to the rear electronic control unit RECU via the CAN bus; control a third object in the current electric vehicle according to the third control signal via the second MOSFET in the RECU, wherein the current electric vehicle is equipped with the RECU and the second MOSFET is built into the RECU.

[0062] The third object includes a breathing light, a license plate light, a tail light and a saddle lock.

[0063] Specifically, such as Figure 3 As shown, the current electric vehicle is equipped with a rear electronic control unit (RECU). The liquid-cooled motor module 110, the left breathing light 111, the license plate light 112, the tail light 113, the saddle lock 114, the right breathing light 115, the battery pack 116, the first heating plate 117, the second heating plate 117, the battery temperature display screen 119 and the charging interface 120 are electrically connected to the RECU respectively, and the connection between the FECU and the RECU is a CAN bus. Multiple MOSFETs can be built into the RECU. The RECU is electrically connected to the main power supply battery of the current electric vehicle (such as a 72V lead-acid battery), and the RECU can power the FECU, MCU, instrument display screen and vehicle handlebars. After receiving the third control signal, these MOSFETs can drive the breathing light, license plate light, taillight and saddle lock.

[0064] S207 : Differentially transmit the current vehicle's wheel speed signal to the instrument display screen via the CAN bus.

[0065] For example, the current control methods for electric vehicles include the following 14 items:

[0066] 1. Receive the analog signal that triggers the push-to-start function. After analog-to-digital conversion, the FECU forwards the analog signal to the RECU via the CAN bus. The RECU then turns on the vehicle's power supply, illuminating the instrument cluster. Simultaneously, the RECU closes the MOSFETs in the left and right breathing lights and the license plate light, illuminating them. The MOSFET in the mobile phone charger also closes.

[0067] 2. Receive the analog signal that triggers the horn switch. After the analog signal is converted to a digital signal, it is forwarded by the FECU to the RECU via the CAN bus. The RECU drives the MOSFET of the horn to close, causing the horn to sound.

[0068] 3. Receive the analog signal that triggers the left and right turn signals. After the analog signal is converted to a digital signal, it is forwarded by the FECU to the RECU via the CAN bus. The RECU turns on the MOSFETs of the left and right turn signals, illuminating them.

[0069] 4. Receive the analog signal that triggers the high and low beams. This analog signal is converted to a digital signal and then forwarded by the FECU to the RECU via the CAN bus. The RECU turns on the MOSFETs of the left and right headlights, illuminating the low beams. Receive the analog signal that triggers the high and low beam switching. This analog signal is converted to a digital signal and then forwarded by the FECU to the RECU via the CAN bus. The RECU activates the low and high beam switching.

[0070] 5. Receive the analog signal that triggers the overtaking switch. After the analog signal is converted to a digital signal, it is forwarded by the FECU via the CAN bus to the digital liquid-cooled motor integrated power control system, triggering acceleration for overtaking.

[0071] 6. Receives the analog signal that triggers the upshift or downshift switch. After the analog signal is converted to a digital signal, it is forwarded by the FECU via the CAN bus to the digital liquid-cooled motor integrated power control system to perform the three-gear shift.

[0072] 7. Receive the analog signal that triggers the double flash switch. After the analog signal is converted to a digital signal, it is forwarded by the FECU to the RECU via the CAN bus. The FECU drives the MOSFETs of the left and right lights to close, causing the left and right turn signals to flash and illuminate.

[0073] 8. Receive the analog signal that triggers cruise control. After the analog signal is converted to a digital signal, it is forwarded by the FECU via the CAN bus to the digital liquid-cooled motor integrated power control system, triggering cruise control.

[0074] 9. Receive the analog signal that triggers reverse. After the analog signal is converted into a digital signal, it is forwarded by the FECU via the CAN bus to the digital liquid-cooled motor integrated power control system to trigger reverse.

[0075] 10. Receive the analog signal that triggers the saddle lock switch. After the analog signal is converted to a digital signal, it is forwarded by the FECU to the RECU via the CAN bus. The RECU drives the MOSFET of the saddle lock to close, and the saddle lock is opened.

[0076] 11. Receive the analog signal that triggers the light-sensing switch. After the analog signal is converted to a digital signal, it is forwarded by the FECU to the RECU via the CAN bus. The FECU activates the light-sensing headlight function.

[0077] 12. Receive the analog signal that triggers the headlight switch. After the analog signal is converted to a digital signal, it is forwarded by the FECU to the RECU via the CAN bus. The FECU turns on the MOSFETs of the left and right headlights, illuminating the headlights.

[0078] 13. Receive the analog signal that triggers the brake switch. After analog-to-digital conversion, the analog signal is forwarded by the FECU via the CAN bus to the RECU and the digital liquid-cooled motor integrated power control system, which activates the brakes. Simultaneously, the taillight MOSFET closes, illuminating the brake lights.

[0079] 14. Receive the analog signal that triggers the throttle signal. After the analog signal is converted into a digital signal, it is forwarded by the FECU via the CAN bus to the digital liquid-cooled motor integrated power control system for speed control.

[0080] The electric vehicle control method provided by the embodiment of the present invention uses MOSFET to drive the control object, greatly extending the service life of the switch, and differentially transmits the digital signal to the control object through the CAN bus, which can effectively suppress interference, reduce wiring costs, and reduce the failure rate caused by poor contact between the plug-in and the wiring harness.
