Title: Vehicle control device
Inventor: SUGIYAMA KOJI
IPC: B60K6/547
Filed: 2017-08-25
Abstract: To achieve both the improvement of the control accuracy of an engine rotating speed and the improvement of drivability according to the operation state of an engine during the shifting of a mechanical transmission mechanism.SOLUTION: When the operation state of an engine 14 is a state of being stopped or a state of warming up a catalyst, as compared to when the operation state of the engine 14 is a state of being normally operated, an engagement hydraulic pressure PRcb of an engaging side engagement device is lowered in the shifting transition of a stepped transmission part 20, so that an engine rotating speed is less likely to vary relative to target rotation. As a result, in the shifting of the stepped transmission part 20 when the operation state of the engine 14 is the state of being stopped or the state of warming up the catalyst, the engine rotating speed can be accurately controlled. In addition, in the shifting of the stepped transmission part 20 when the operation state of the engine 14 is the state of being normally operated, a shifting time can be reduced. Thus, during the shifting of the stepped transmission part 20, the improvement of the control accuracy of the engine rotating speed and the improvement of drivability can be both achieved according to the operation state of the engine 14.SELECTED DRAWING: Figure 7
