[0006] To achieve the above object, the present invention provides the following technical solution: a combined wireless remote control method for a two-wheeled electric vehicle, comprising the following steps: Step S01: Multi-band communication channel detection: It is used to install antennas of commonly used frequency bands inside the remote control receiver of the two-wheeled electric vehicle, detect the channel quality of each frequency band according to the set period, and calculate the channel quality score of each frequency band.

[0007] Step S02: Multi-band communication channel switching: used to receive the channel quality score of the target frequency band transmitted in the multi-band communication channel detection step, compare it with the preset channel quality score and switching threshold, and trigger the frequency band switching judgment process.

[0008] Step S03: Vehicle signal acquisition: The user uses the remote control to send a pairing signal to the receiving end through the target frequency band. After verifying the legitimacy of the signal source, the pairing is completed. After the vehicle is started, the sensor signal of the two-wheeled electric vehicle is collected.

The ranging unit is used to detect the distance between the remote control and the vehicle, the power adjustment unit is used to receive a control signal to adjust the transmission power, and the control unit is used to receive data from the ranging unit, calculate the appropriate transmission power according to a preset algorithm, and send a control signal to the power adjustment unit.

[0012] Preferably, the multi-band communication channel detection is specifically as follows: S11: A remote control receiver is mounted on the front of the two-wheeled electric vehicle. An antenna with a commonly used frequency band is built into the remote control receiver. The antenna is designed with a flexible substrate and can be flexibly adjusted according to the internal space of the remote control receiver. S12: Set up a periodic scanning mechanism that adjusts the time interval according to the ambient noise level and detects the channel quality of each frequency band; S13: The MCU (microcontroller unit) controls the RF switch to switch to the antenna of the target frequency band, configures the wireless chip to enter the receiving mode, reads the signal strength value of the signal strength register of the target frequency band after stabilization, measures the signal power during the valid signal period, measures the noise power during the no-signal period or idle channel, calculates the signal-to-noise ratio of the target frequency band, sends standard test frames at the set time interval, and calculates the bit error rate of the target frequency band by the ratio of the number of received error bits to the total number of bits; S14: Calculate the channel quality score of each frequency band based on signal strength, signal-to-noise ratio, and bit error rate.

[0013] Preferably, the multi-band communication channel switching is specifically as follows: The trigger condition for frequency band switching is the preset channel quality score minus the switching threshold. The channel quality score of the target frequency band is obtained and compared with the trigger condition value of the frequency band switching. If the channel quality score of the target frequency band is greater than the trigger condition value of the frequency band switching, it indicates that the channel quality of the current frequency band is excellent, and the frequency band switching is not performed. When the channel quality score of the target frequency band is less than or equal to the trigger condition of the frequency band switching, it is determined that the channel quality of the current frequency band is poor, and the frequency band switching is triggered.

If the driving risk assessment coefficient is greater than the maximum value of the preset driving risk assessment coefficient judgment interval, it indicates that there is a serious safety hazard in the current driving state of the two-wheeled electric vehicle, triggering an emergency braking response strategy. At this time, the vibration motor of the remote control device is activated through wireless remote control tactile feedback, and the vibration intensity is adjusted according to the type of safety protection response strategy, reminding the user to send an emergency braking command to the vehicle receiving end through the remote control. After the vehicle receiving end receives the emergency braking command, it immediately performs an emergency braking operation to ensure that the two-wheeled electric vehicle is safely stopped and avoid accidents. S43: If the driving risk assessment coefficient is less than or equal to the maximum value of the preset driving risk assessment coefficient judgment interval and greater than the minimum value of the judgment interval, it indicates that there is a certain safety hazard in the current driving state of the two-wheeled electric vehicle, and a warning prompt response strategy is triggered. At this time, the vibration motor of the remote control device is activated through wireless remote control tactile feedback, and the vibration intensity is adjusted according to the type of safety protection response strategy to remind the user to take corresponding safety measures. Specific safety hazard information is displayed on the touch screen equipped with the remote control; S44: If the driving risk assessment coefficient is less than or equal to the minimum value of the preset driving risk assessment coefficient judgment interval, it indicates that the current driving state of the two-wheeled electric vehicle is safe and no operation is performed.

After receiving the signal, the power adjustment unit compares the actual power with the current transmit power deviation. If the deviation exceeds the allowable range, the transmit power is adjusted to the current transmit power. Otherwise, the transmit power is not adjusted.

[0017] Preferably, the combined wireless remote control device for the two-wheeled electric vehicle includes: a processor, a memory, and a program or instruction stored in the memory and executable on the processor.

[0018] Technical effects and advantages of the present invention: 1. The present invention provides a combined wireless remote control method and device for a two-wheeled electric vehicle. By installing an antenna for a commonly used frequency band inside the remote control receiver of the two-wheeled electric vehicle, the method detects the channel quality of each frequency band according to a set period. Based on signal strength, signal-to-noise ratio, and bit error rate, the method calculates a channel quality score for each frequency band, compares the score with a preset channel quality score and switching threshold, and triggers a frequency band switching judgment process.
