WORK VEHICLE AND CONTROL METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2015/104937
Kind Code:
A1
Abstract:
A control unit for a work vehicle has a transmission request determining unit, a command torque determining unit, and a traction limiting unit. The transmission request determining unit determines the request traction on the basis of the operation amount of an accelerator operating member. The request traction is the target traction for a traveling device. The command torque determining unit determines the output torque of an electric motor so that the vehicle traction is the request traction. The traction limiting unit reduces the request traction below a value according to the operation amount of the accelerator operating member when the vehicle is excavating.
