AI Technical Summary

Technical Problem

Existing zero-steering lawnmowers have a balance problem between response speed and anti-overshoot in speed control, resulting in slow start-up, insufficient dynamic following ability, and affecting the accuracy of driving trajectory and operating experience.

Method used

It adopts dual-channel parallel processing logic, generates target speed correction through integral operation, and superimposes it with the original target speed to form dynamic target speed. Combined with proportional operation, it generates the final control signal and performs specific processing for different working conditions, such as emergency reset, saturation obstruction and steering differential working conditions.

Benefits of technology

It improves the speed response sensitivity and dynamic following ability of the zero-steering lawnmower under varying working conditions, ensures smooth driving and steering control precision, shortens system response time, and improves overall work efficiency and safety.

Abstract

This application relates to a method and related apparatus for rapid motor response control of a zero-steering lawnmower. The method includes: establishing dual-channel parallel processing logic for the left and right drive wheels to obtain the original target speed and actual feedback speed for each channel; performing an integral operation on the speed error between the original target speed and the actual feedback speed to generate a target speed correction amount for each channel; superimposing the target speed correction amount and the original target speed to generate a dynamic target speed for each channel; and performing a proportional operation based on the instantaneous error between the dynamic target speed and the actual feedback speed to generate the final control signal for each channel. This application has the advantage of converting integral operations into active command guidance, improving the dynamic following ability and response sensitivity of the zero-steering lawnmower, while avoiding overshoot to ensure vehicle stability.
