Title: Vehicular control apparatus
Inventor: TAKEBAYASHI NORITAKA
IPC: B60W10/11
Filed: 2019-06-14
Abstract: To suppress generation of dragging in a release-side engagement device caused by a shortage of hydraulic oil in a canceller chamber when start-accelerating right after starting a traveling drive force source.SOLUTION: When a traveling drive source is restarted after returning from an automatic stopping of the traveling drive force source followed by an accelerator being stepped on to start, an input rotation speed (a read-ahead input rotation speed) ωis is calculated when a read-ahead time Ts has elapsed. A piston pressing power prediction value Fpp of a release-side engagement device after the read-ahead time Ts elapses is calculated on the basis of centrifugal pressure generated in hydraulic oil in a pressure chamber and canceller chamber in accordance with the read-ahead input rotation speed ωis, and in a case where the piston pressing power prediction value Fpp is equal to or larger than a dragging determination value α, an increase of an input rotation speed ωi is suppressed by advancing an upshift. This causes suppression of an increase in piston pressing force due to an increase in the input rotation speed ωi, thus suppressing occurrence of dragging in the release-side engagement device due to a shortage of hydraulic oil within the canceller chamber.SELECTED DRAWING: Figure 8
