TRANSMISSION HYDRAULIC CONTROL APPARATUS |
摘要 |
A hydraulic pressure control device for a transmission, the hydraulic pressure control device configured to operate a prescribed hydraulic apparatus by hydraulic pressure generated by an oil pump to be driven during operation of a driving force source, for which automatic stop control is performed according to at least one of a vehicle speed and a request drive amount, to accumulate the hydraulic pressure in a pressure accumulator, and to supply the hydraulic pressure accumulated in the pressure accumulator to the hydraulic apparatus when the driving force source is automatically stopped, wherein: the automatic stop control includes control to stop the driving force source during travel in which the vehicle speed is equal to or higher than a prescribed vehicle speed; and the hydraulic pressure control device is configured to perform a pressure accumulation control to control an accumulated oil amount in the pressure accumulator and the automatic stop control in a cooperative manner so as to increase the accumulated oil amount of the pressure accumulator when the driving force source is automatically stopped during travel. |
