Abstract (en)
Method (20) for controlling in a closed loop a work vehicle (1) including: an engine (3); a control unit (6); a sensor (5); a selector device (12) configured to permit the operator to select or define an acceleration profile (22); and a throttle input device (10). The method comprises the steps of: acquiring a ground speed (v<sub>ground</sub>) or, alternatively, a ground acceleration (a<sub>ground</sub>) of the work vehicle (1) through the sensor (5) ; generating (28) a throttle engine command (ω<sub>throttle</sub>) indicative of a position of the throttle input device (10); acquiring the acceleration profile (22) through the selector device (12); generating (26, 38; 26) a setpoint quantity (v<sub>set</sub>; a<sub>set</sub>) based on the acceleration profile (22); generating (30; 130) a profile engine command (ω<sub>profile</sub>; ω'<sub>profile</sub>) based on both the setpoint quantity (v<sub>set</sub>; a<sub>set</sub>) and either the ground speed (v<sub>ground</sub>) or, alternatively, the ground acceleration (a<sub>ground</sub>) ; generating (32) an engine command (ω<sub>eng</sub>) by selecting among at least the profile engine command (ω<sub>profile</sub>; ω'<sub>profile</sub>) and the throttle engine command (ω<sub>throttle</sub>) to control the engine (3) .
