    摘要: There is provided a hydraulic control device for controlling a hydraulic pressure supplied to a vehicle start-up engagement element in an automatic transmission when a shift lever is moved from a non-drive range position to a drive range position. The hydraulic control device has a target pressure setting section that sets, based on an input torque of the automatic transmission, a target value of hydraulic pressure supplied to the vehicle start-up engagement element at the completion of engagement of the vehicle start-up engagement element and corrects the target value periodically based on the transmission input torque until the completion of engagement of the vehicle start-up engagement element and a hydraulic pressure control section that controls the hydraulic pressure in such a manner that the hydraulic pressure supplied to the vehicle start-up engagement element reaches the corrected target value at the completion of engagement of the vehicle start-up engagement element.

    摘要: A brake pressure predetermined value (Pa) required to bring a vehicle to a standstill while the vehicle is stationary is calculated on the basis of a slope angle (θ), and when the position of a shift lever 7 is in a driving range, a vehicle speed (V) is equal to or lower than a predetermined vehicle speed (Va), and a brake pressure (P) is equal to or greater than the brake pressure predetermined value (Pa), neutral control is performed to disengage a forward-reverse switching clutch 4 provided between an engine 1 and a continuously variable transmission 5.
