METHOD FOR CONTROLLING ENGINE OF VEHICLE HAVING POWER EXTRACTION MECHANISM AND DEVICE FOR CONTROLLING ENGINE OF VEHICLE HAVING POWER EXTRACTION MECHANISM

WIPO Patent Application WO/2010/071096

A1

A work vehicle having a power extraction mechanism for controlling the engine rpm according to an all-speed map can surely detect and check a failure of the rotation control due to generation of defective data caused by a failure of a semiconductor storage element. If the actual engine rpm calculated in a second area arranged in an electronic control unit (1) according to the running state of the vehicle inputted from outside is found to be greater than the sum obtained by adding a predetermined allowable rpm increase to a target engine rpm determined according to the correlation predetermined for the torque preset in accordance with the detected accelerator open degree and the all-speed map, the torque determined by the all-speed map in the first area provided for the actual vehicle operation control is subjected to a gradual decrease regulation accompanying the actual engine rpm increase in the second area, thereby executing the engine control in the first area.
