<P>PROBLEM TO BE SOLVED: To solve the problems such as a creep phenomenon, a starting time lag to accelerator operation, an engine overrun when an accelerator operation quantity is suddenly reduced in traveling and an engine stall when a load suddenly increases in traveling, in a vehicle having a power train having an HST (a hydrostatic transmission). <P>SOLUTION: An HST controller 15 in the power train 10 controls maximum absorbing torque of an HST pump 23 in response to an accelerator operation quantity. While, when the accelerator operation quantity suddenly reduces in traveling of the vehicle, or when an engine speed suddenly reduces in traveling of the vehicle, the maximum absorbing torque of the HST pump 23 is controlled in response to the engine speed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
