Document Type and Number:
Japanese Patent JP5049782
Kind Code:
B2
Abstract:
A retarder control system for a working vehicle includes: an input shaft revolution speed detector (121) for detecting an input shaft revolution speed of a transmission; a running state acquirer (33) for acquiring a running state of the working vehicle; a threshold map storage (321) for storing a plurality of threshold maps of an input shaft revolution speed at which the retarder braking control starts or ends in accordance with a predetermined running state of the working vehicle; a threshold map selector (34) for selecting a threshold map from the threshold maps stored in the threshold map storage based on the running state acquired by the running state acquirer; and a braking controller (35) for retarder braking control based on the input shaft revolution speed of the transmission detected by the input revolution speed detector (121) and the threshold map selected by the threshold map selector (34).
