Title:
HYBRID-ELECTRIC VEHICULAR CONTROL APPARATUS
Document Type and Number:
Japanese Patent JP2023035722
Kind Code:
A
Abstract:
To appropriately suppress a clattering shock when changing from a driven travel to a driving travel, regardless of a difference in inertia of a drive source side.SOLUTION: During a travel in a BEV travel mode where a K0 clutch is disengaged, with an engine separated from a power transmission path, and where inertia on a drive source side is relatively small, a play is reduced by gradually increasing target input torque Tinbev at a change rate (Φhev1>Φbev1) smaller than that during a travel in an HEV travel mode with the K0 clutch engaged, when gradually increasing the target input torque Tinbev in a play-reducing zone (a time t2-t3 zone) in which a differential rotation ΔN changes from negative to positive. By so doing, it is possible to change the differential rotation ΔN from the negative to positive in an approximately the same changing pattern regardless of a difference in inertia, making it possible to suppress a clattering shock with a play appropriately reduced in any travel mode.SELECTED DRAWING: Figure 3
