WORK VEHICLE AND METHOD FOR CONTROLLING WORK VEHICLE

摘要

The shuttle action evaluating unit determines that the vehicle is in a shuttle action when the direction relative to the position of the forward/reverse travel operating member differs from the travel direction of the vehicle. The target input shaft torque determination unit determines a target input shaft torque. The target output shaft torque determination unit determines a target output shaft torque so that a deceleration force for decelerating the vehicle is generated on the output shaft of the power transmission device in a state in which connection and disconnection states of the forward travel clutch and the reverse travel clutch are maintained at the state before the start of the shuttle action when the shuttle action is started. The torque-balance information is stored in a storage unit and defines a relationship between the target input shaft torque and the target output shaft torque so as to achieve a balance of the torques of a power transmission device. The command torque determination unit uses the torque-balance information to determine torque commands to the motor from the target input shaft torque and the target output shaft torque.
