PROBLEM TO BE SOLVED: To provide a control device of a hydrostatic pressure assist vehicle which includes a hydrostatic pressure assist mechanism and also outputs torque requested by a driver during driving to improve drivability.SOLUTION: A device includes a pump/motor connected to an in-vehicle engine and an accumulator, the pump/motor is operated as a pump and a hydrostatic pressure is discharged and accumulated in the accumulator during deceleration, and the pump/motor is operated as a motor and an engine drive is assisted by the accumulated hydrostatic pressure during starting etc. In the device, request torque requested by a driver is calculated based on a detected accelerator opening and a vehicle speed (110a), output possible torque is calculated by a hydrostatic pressure assist mechanism based on the calculated request torque and a detected engine speed (110b), and torque to be output from the engine is calculated by subtracting the calculated output possible torque from the calculated request torque (110f). |
