Title:
CENTRIFUGAL COMPENSATION CONTROL METHOD, APPARATUS AND SYSTEM FOR TRANSMISSION, AND STORAGE MEDIUM AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/262673
Kind Code:
A1
Abstract:
A centrifugal compensation control method for a transmission. The method comprises: collecting a vehicle working condition signal; determining a vehicle condition state of a vehicle according to the vehicle working condition signal; collecting a hydraulic module signal; determining an oil filling state of a clutch according to the hydraulic module signal; and executing centrifugal compensation on a transmission according to the vehicle condition state of the vehicle and the oil filling state of the clutch. The identification for an accelerator pedal signal, an ESP signal, a vehicle speed signal and a vehicle gear signal is taken as a determination condition of a centrifugal compensation control policy for a vehicle condition state of a vehicle, and the identification for location signals of a hydraulic module piston and a hydraulic valve plate is taken as a determination condition of the centrifugal compensation control policy for a centrifugal compensation involvement time. Therefore, the operation coverage range of a vehicle working condition of a centrifugal compensation control policy is widened, abnormal noise generated during the starting or gear shifting of a DCT is reduced, the impact to a shifting gear is reduced, and the service life of a transmission gear is thus prolonged. The present application further relates to a centrifugal compensation control apparatus and system for a transmission, and a storage medium and a vehicle.
