AI Technical Summary
Technical Problem
In existing technologies, adding additional sensors increases vehicle costs, while transmissions without sensors cannot effectively determine clutch wear and alert the driver.
Method used
By acquiring the cumulative slippage work of the clutch based on the driving data of the target vehicle, and using big data analysis methods of vehicle clusters to calculate the threshold of cumulative slippage work for clutch plate failure, comparison and early warning can be achieved, avoiding the need to install additional sensors.
Benefits of technology
It enables real-time monitoring and early warning of manual transmission clutch wear, reducing vehicle costs and improving the accuracy of wear assessment.

Abstract
本申请涉及一种变速箱离合器磨损预警方法及系统，其包括：基于目标车辆的行驶数据，获取单位时间内，目标车辆的离合器累计滑摩功，行驶数据包括发动机扭矩、离合器转速差、离合器打滑持续时间；基于车辆集群中每一台车辆的离合器累计滑磨总功，获取目标车辆的离合器片失效累计滑摩功阈值；其中，车辆集群包括与目标车辆同类型的参照车辆，车辆的离合器累计滑磨总功包括：以该单位时间为起始点，向前推的预设时间段内，该车辆离合器维修所有次数中，其中的两次维修对应的时间以及之间的所有单位时间对应的离合器累计滑摩功之和；将目标车辆的离合器累计滑摩功与目标车辆的离合器片失效累计滑摩功阈值进行对比；根据对比结果，进行预警。
