WORKING VEHICLE ENGINE OUTPUT CONTROL SYSTEM AND METHOD
摘要
<p>It is an object to solve a problem that occurs in such a condition that a torque converter of a working vehicle is inclined to stall or stalls. A speed ratio at the time when a torque ratio (t) of a torque converter (4) is larger than a torque ratio (t1) at the time of the maximum efficiency (?max) is determined in advance as a speed ratio threshold value (ec). Such a speed ratio is stored at a memory unit (22) of a controller (20). An engine output reduction means (23) of the controller (20) carries out the control to reduce an output (Pe) of an engine (3) in the case where a speed ratio (e) subjected to an arithmetic operation is not larger than the speed ratio threshold value (ec).</p>
