AI Technical Summary

Technical Problem

Motorcycle gear shifting is cumbersome, the shifting process is not smooth and is prone to jerking, and the power interruption time is long. The driver needs to closely coordinate the operation of the throttle and clutch.

Method used

By acquiring the motorcycle's shifting intention signal, combined with engine speed and load, and retrieving the ignition timing push-back angle table, the engine is controlled to perform ignition timing adjustment and periodic fuel cut-off-resumption operations, achieving automatic shifting without the need for the driver to operate the clutch.

Benefits of technology

It simplifies the gear shifting process, shortens the power interruption time, and improves the driving experience, making it especially suitable for novice drivers. The gear shifting process is smoother and faster.

Abstract

The application provides a motorcycle gear shifting control method, system, readable storage medium and motorcycle. The motorcycle gear shifting control method first acquires a gear shifting intention signal of the motorcycle, and determines the gear shifting intention of the motorcycle according to the gear shifting intention signal. Then, the current gear, engine speed and engine load of the motorcycle are acquired, and a corresponding relationship table of the gear, engine speed and engine load and the ignition timing retardation angle corresponding to the gear shifting intention of the motorcycle is retrieved to obtain the ignition timing retardation angle of the engine. Then, the ignition advance angle of the engine in the current gear is obtained according to the ignition timing retardation angle and the basic ignition angle. Finally, the gear shifting control information of the engine is acquired for control according to the ignition advance angle and the minimum ignition advance angle of the engine. The motorcycle gear shifting control method provided by the application makes the gear shifting process simple, is very friendly to novice drivers, and has a short gear shifting process time, a short power interruption time and a better driving experience.
