摘要： A method of controlling a propulsion system of a utility or agricultural vehicle, wherein the propulsion system comprises a prime mover (E) and a hydraulic transmission (HY) including a variable displacement pump (HP) configured to be driven in rotation by the prime mover and a variable displacement hydraulic motor (HM), operatively connected to the pump by means of a forward hydraulic line (F) and a return one (R), the method providing for monitoring of the (Chk 1) lever inclination of accelerator that exceeds a limit position (AL) and of the (Chk 2) rotation speed of the prime mover is equal to or greater than said limit speed (SL), and when said conditions are simultaneously verified the method foresees (Tr1) switching of the system from a first (ST1) operating mode in which the accelerator controls the rotation speed of the prime mover to a second operating mode (ST2) in which the accelerator controls the hydraulic pump m while the motor is operated at a fixed speed.

摘要： The hydrostatic transmission (100) for a work vehicle (10) comprises: a hydraulic pump (30) coupled to an internal combustion engine (28) and an electronically controlled variable displacement hydraulic motor (32) connected to driving wheels (16), jointly defining a closed hydraulic circuit (1); a first pressure sensor (111), a second pressure sensor (112) and a speed sensor (113) to sense, respectively, the pressure (p f ) on a forward line (101), the pressure (p b ) on a rearward line (102) and the speed (u v ) of the vehicle (10); and an electronic control unit (ECU) configured to set a commanded displacement (V cmd ) of the hydraulic motor (32) equal to the greater of a first displacement (V p ) and a second displacement (V v ); wherein the first displacement (V p ) is a function of the pressure (p f ) on the forward line (101) if the vehicle (10) is moving forward, or the pressure (p b ) on the rearward line (102) if the vehicle (10) is moving rearward; and wherein the second displacement (V v ) is a function of the speed (u v ) of the vehicle (10).

摘要： A wheel loader includes: a mechanical drive unit; a mechanical drive clutch (43, 47) controlling transmission/cutoff of a power in the mechanical drive unit; an HST pump (22) driven by an engine; a hydraulic motor (23, 24) driven by a hydraulic oil delivered from the HST pump (22); a hydraulic drive unit; a hydraulic drive clutch (54, 65) controlling transmission/cutoff of a power in the hydraulic drive unit; a load detecting unit (101) detecting an amount of a load; a vehicle speed sensor (116) detecting a vehicle speed; a switching controlling unit (102) setting a switching vehicle speed in accordance with the amount of the load; and a vehicle-body controller (100) switching between mechanical drive state and hydraulic drive state based on the switching controlling unit (102). The switching controlling unit (102) sets the switching vehicle speed at a high-speed side when the load becomes large and at a low-speed side when the load becomes small.
