<p>A retarder control device for a working vehicle has a input shaft speed detection means (121) for detecting the rotation speed of the input shaft of a transmission, a traveling condition acquisition means (33) for acquiring traveling conditions of the working vehicle, a threshold map storage means (321) having stored in it threshold maps of the input shaft speed, the threshold maps starting and/or canceling braking control by a retarder according to preset traveling conditions of the working vehicle, a threshold map selection means (34) for selecting, based on the traveling conditions acquired by the traveling condition acquisition means, a threshold map stored in the threshold map storage means, and a braking control means (35) for performing braking control of the retarder based on the transmission input shaft speed detected by the input shaft speed detection means (121) and on the threshold map selected by the threshold map selection means (34).</p> |
