Title:
ENGINE CONTROL DEVICE FOR WORKING VEHICLE
Document Type and Number:
WIPO Patent Application WO/2007/080731
Kind Code:
A1
Abstract:
Traction force and lifting force are appropriately balanced by simple control to
enhance workability of a self-propelled working vehicle. An engine control device
for the self-propelled working machine has a hydraulic pump (7) for driving a
working machine, and the engine control device has a vehicle speed sensor (26) for
detecting vehicle speed and also has traction force control means (10). The traction
force control means (10) reduces, based on the result of detection by the vehicle
speed sensor (26), traction force by limiting an upper limit of a throttle amount
when the vehicle speed is lower than a predetermined level.
