<p>In order to reduce fuel consumption while reducing as much as possible the effect on the vehicle travel speed, provided is a hydraulically driven vehicle that is equipped with a travel hydraulic pump (11) and a travel hydraulic motor (12) which are connected via a pair of main oil passages (13A, 13B), an engine (1) for driving the travel hydraulic pump (11), and a control unit (130) for implementing a torque control such that the output torque outputted from an output shaft (1a) of the engine (1) becomes the target torque, wherein oil is circulated and supplied from the travel hydraulic pump (11) via the pair of main oil passages (13A, 13B) to drive the travel hydraulic motor (12) so as to make travel possible. The hydraulically driven vehicle is equipped with a regeneration accumulator (51) which is connected to the main oil passage that will become the high pressure side during travel deceleration, and which accumulates oil therein. A regeneration hydraulic motor (52) is driven by the oil accumulated in the regeneration accumulator (51).</p> |
