    摘要： A steering method and steering system which enable a minimum turn radius more than the discharge capacities of a hydraulic motor and a hydraulic pump and which positively prevent the unstable traveling and turning behavior of a vehicle when the vehicle makes a pivot turn. The vehicle is provided with a pair of brakes for right and left output shafts and designed to transmit the driving force of the hydraulic motor to the output shafts through planetary gear mechanisms. During a pivot turn of the vehicle, an operation of the brake of either one of the right and left output shafts and a transmission of a driving force from the hydraulic motor to a planetary gear mechanism are simultaneously carried out for a specified period of time and thereafter, the transmission of the driving force from the hydraulic motor to the planetary gear mechanism is interrupted.

    摘要： The present invention provides a drive device for a working vehicle whereby gear change shock during the forward/reverse running changeover action can be reduced while achieving shortening of cycle time and protecting various clutch mechanisms in the transmission. If a reverse running command is output from a running control device while the vehicle is running forward, an ECMV controls a braking force of a brake device so as to reduce a vehicle speed through a first prescribed speed to a second prescribed speed, and disengages the forward clutch. When the vehicle speed reaches the first prescribed speed, the ECMV puts the reverse clutch in a slipping action condition and, after the vehicle speed reaches the second prescribed speed, gradually engages the reverse clutch.

    摘要： A vehicle control system which is capable of performing a quick decelerating operation in all vehicle speed regions and setting a direct region where power from an engine is transmitted through a mechanical transmission unit only in a hydro-mechanical transmission. The vehicle control system includes an engine and a hydro-mechanical transmission and is designed to set a tractive force-vehicle speed characteristic corresponding to the direct region where power transmission from the input shaft to the intermediate output shaft of the hydro-mechanical transmission is done by the mechanical transmission unit alone in a specified engine speed region. An engine control system controls the engine and a decelerator outputs a deceleration command according to an operating amount thereof. The engine control system controls the engine to reduce engine output torque corresponding to a specified engine speed region in response to the deceleration command.
