Abstract: A transmission device is provided with a hydraulic control device, which has a pump for generating hydraulic pressure using power from a motor, and an accumulator, and which controls hydraulic pressure and supplies the hydraulic pressure to a hydraulic servo of an engagement element. The transmission device executes, when the motor that automatically stopped starts up with a request for vehicle travel: a fill control in which the hydraulic control device is controlled so that the hydraulic servo is being filled with working oil; a standby control to control the hydraulic pressure in the hydraulic servo at a standby pressure; and an engagement control to increase the hydraulic pressure in the hydraulic servo is started when the rotational speed of the motor becomes reaches or exceeds a prescribed rotational speed, after hydraulic pressure accumulated in the accumulator is released into the hydraulic circuit, so that the engagement element is engaged.

Abstract: A road slope estimating device which is mounted on a vehicle and estimates a slope of a road on which the vehicle is traveling, the vehicle including a motor and a transmission capable of changing a shift speed by an engagement switching operation of disengaging one of a plurality of engagement elements and engaging another one of the plurality of engagement elements, and outputting power from the motor via the transmission to travel. An estimating section carries out first road slope estimation from the computed output torque and acceleration of the vehicle until transfer of torque is handed over from the engagement element to be disengaged of the plurality of engagement elements to the engagement element to be engaged. Second road slope estimation is estimated from the computed output torque and the acceleration of the vehicle when the handover of the transfer of torque is carried out.
