Background Because of its flexible traffic performance, motorcycles are often used as vehicles in a variety of road conditions. The motorcycle may have an excessively high speed during running, which may cause a driving accident due to the risk of rolling of the body during straight running or cornering. For example, when the speed of the motorcycle is too high, the sudden jolt may cause the phenomenon that the motorcycle is inclined when passing over a rough road surface, and thus a safety accident occurs, and for example, when the voltage applied to the acceleration assembly is too high, the speed of the motorcycle is too high, and thus the safety accident of the motorcycle is caused. Currently, in the running process of a motorcycle, a driver performs acceleration operation (such as a rotary acceleration assembly) through the rotary acceleration assembly, adjusts the voltage value of a Hall element through the acceleration assembly so as to adjust the voltage value of an input circuit, and controls a power source to apply power to wheels of the motorcycle according to the voltage value of the input circuit, so that the acceleration of the motorcycle is realized. However, in the case of loosening or failure of the acceleration assembly, it cannot be ensured that the power applied to the wheels by the power source according to the voltage value of the input circuit when the acceleration assembly rotates conforms to the intention of the driver, and an excessive or insufficient power may occur, thereby resulting in lower safety of the motorcycle during running.
