[0042] In order to facilitate the understanding of the present invention, some preferred embodiments of the present invention are further described below.

[0043] The following describes the working process of the present invention using a relatively common scenario as an example. The working process is as follows: Step 1: Obtain the vehicle's location, speed, temperature, humidity, wind speed, wind direction and other information; Step 2: Preprocess the acquired vehicle data, including data collection and data cleaning; Step 3: Construct a formula algorithm based on vehicle speed, communication signal strength and signal frequency to generate a communication transmission strategy; Step 4: Perform communication transmission between electric bicycles according to the generated communication transmission strategy; Step 5: Monitor the influencing factors in the communication process in real time and dynamically adjust the communication transmission strategy.

[0044] Preferably, in step 1, multiple sensors are used to obtain vehicle information, including a GPS module to obtain location information, a speed sensor to obtain speed information, a temperature sensor to obtain temperature information, a humidity sensor to obtain humidity information, a wind speed sensor to obtain wind speed information, and a wind direction sensor to obtain wind direction information. The data collection frequency can be adjusted according to actual needs, for example, once per second or once per minute; It should be noted that the accuracy and frequency of data acquisition directly affect the effect of subsequent data processing. Therefore, high-precision sensors should be selected and the acquisition frequency should be set reasonably.

[0045] Preferably, in step 2, data preprocessing includes data cleaning and data correction. Data cleaning removes noise and outliers by filtering, smoothing and other methods to ensure the accuracy and consistency of the data. Data correction eliminates system errors by zero point correction, linear correction and other methods. Data integration integrates data from different sensors into a unified data set to facilitate subsequent processing and analysis.

[0046] Preferably, in step 3, based on the vehicle speed, communication signal strength and signal frequency, a calculation formula for constructing a comprehensive function is as follows: in, Indicates the comprehensive signal strength. , , , and is a constant, represents the vehicle speed, Signal frequency, continuously optimize the parameters in the formula through least squares method, gradient descent method or genetic algorithm to ensure the accuracy of the model; It should be noted that the construction and optimization of formula algorithms are the key to generating effective communication transmission strategies, and they need to be verified and adjusted multiple times based on actual data.

[0047] Preferably, in step 4, communication transmission between electric bicycles is performed according to the generated communication transmission strategy. The communication strategy includes the optimization settings of signal frequency, strength, modulation mode and coding mode. For example, when the vehicle speed is high, the signal frequency is appropriately reduced to reduce the influence of the Doppler effect; when the communication distance is far, the signal strength is increased to compensate for signal attenuation.

[0048] It should be noted that the implementation of communication transmission strategies needs to take into account changes in the actual communication environment and ensure communication quality under different conditions.

[0049] Preferably, in step 5, various influencing factors in the communication process are monitored in real time, such as communication distance, obstacles, weather, electromagnetic interference, etc. According to the monitoring results, the communication transmission strategy is dynamically adjusted to ensure the communication quality. The monitoring method includes real-time data stream processing and sensor fusion.

[0050] It should be noted that real-time monitoring and dynamic adjustment are the key to improving the robustness and adaptability of communication systems. Timeliness of monitoring and effectiveness of adjustment must be ensured; Preferably, the present invention also adds a competition mechanism, such as setting a reward mechanism in the vehicle-to-vehicle communication model to encourage electric bicycle users to actively participate in communication and information sharing. Reward users through points, coupons, etc. to improve communication efficiency; It should be noted that competition mechanisms and user incentives can increase user participation and system activity, and further optimize the performance of the communication system.

[0051] Through the above specific implementation methods, the present invention can effectively optimize the communication transmission strategy between electric bicycles, improve the communication quality and transmission efficiency. At the same time, by introducing competition mechanism and user incentive measures, the practicality of the system and user experience are further improved.

[0052] Reference Figure 2 The vehicle-to-vehicle communication between the electric bicycles includes two communication modes: direct communication transmission and indirect information exchange through the Internet of Vehicles.

[0053] Furthermore, in direct communication transmission, under the premise of determining the vehicle-to-vehicle network, the electric bicycle and the electric bicycle Signals can be directly transmitted and received to share real-time information. This method is suitable for low-latency data exchange between vehicles, which helps to transmit key information such as driving status, location, speed, etc., and ensure safe distance and driving coordination between vehicles; Furthermore, the electric bicycle Internet of Vehicles serves as a hub, and each vehicle uploads its own data and shares it with other vehicles. and the electric bicycle The respective status packets (such as data packets and data packets ) is sent to the Internet of Vehicles, and other connected vehicles can obtain this information through the network.

[0054] Combining direct communication and vehicle networking, vehicles can share information at the local and global levels, improving the overall e-bike communication transmission efficiency.

[0055] In summary, the present invention provides a communication transmission control method for an electric bicycle, the method comprising: acquiring electric bicycle data, the electric bicycle data comprising vehicle location data, speed data, battery status data, its own historical data and historical communication rate; based on the electric bicycle vehicle networking, performing data processing operations on the battery status data to obtain a data packet of the battery status, performing data updating operations on the data packet and its own historical data to obtain an updated data packet; performing calculation operations based on the updated data packet to obtain a connectivity index and a communication reception rate of the electric bicycle, and analyzing the connectivity index and the communication reception rate to obtain a correlation between the electric bicycle and other vehicles.
