AI Technical Summary

Technical Problem

Existing clutch slip control methods use current curves with fixed parameters, which may lead to shocks, increased wear, or inconsistent performance during gear shifting, affecting clutch life and shifting smoothness, especially under high load and variable environments.

Method used

By acquiring the target slip current curve corresponding to the current gear, obtaining the parameters of the current and next curve segments, and dynamically adjusting them according to real-time vehicle speed and torque, the slip control parameters are dynamically adjusted to achieve smooth gear shifting and extend clutch life.

Benefits of technology

It enables smooth gear shifting under different operating conditions, reduces clutch wear and impact, extends clutch service life, and adapts to various operating condition changes.

Abstract

This invention relates to the field of vehicle technology and discloses a clutch slippage control method, device, vehicle, medium, and product. The method includes: acquiring a target slippage current curve corresponding to the current gear, and acquiring current curve segment parameters and next curve segment parameters based on the target slippage current curve; performing current slippage control based on the current curve segment parameters, and acquiring the current vehicle speed and current torque at the end of the current slippage control; dynamically adjusting the next curve segment parameters based on the current vehicle speed and current torque to obtain adjusted curve segment parameters, and performing subsequent slippage control based on the adjusted curve segment parameters until the subsequent slippage control ends. By selecting different slippage current curves for different gears, and dynamically adjusting the next curve segment parameters based on real-time vehicle speed and torque after completing slippage control based on each curve segment parameter, smooth gear shifting and extended clutch life can be achieved, adapting to various operating conditions.
