Patent
·
OSTI ID:5556079
This patent describes a method of controlling vehicle deceleration during shuttle shifting of a power shift transmission having clutches for selectively interconnecting an input drive shaft, an output drive shaft, and gears rotatably housed in the transmission in driving relationship with the input and output drive shafts such that a selective engagement of the clutches will effect a varying of the speed of operation of the output shaft for a given speed of operation of the input shaft. The preselected gear ratios from a low speed to a high speed power shift transmission further having an electrical control system responsive to switches actuated by manual movement of a gearshift lever between positions for controlling clutches in the transmission.
