TRAVELLING CONTROLLER FOR HYDRAULIC DRIVEN VEHICLE AND HYDRAULIC DRIVEN VEHICLE

摘要

PROBLEM TO BE SOLVED: To prevent an excessive rotation of a travelling motor upon moving on a downward slope while an accelerator pedal is stepped on. SOLUTION: A manipulated variable of the accelerator pedal 22a is detected by a pressure sensor 41. A function generator 501 outputs target rotating speed Nt of an engine 1 corresponding to the manipulated variable of the accelerator pedal 22a. Travelling driving pressure P is detected by a pressure sensor 42. When the travelling driving pressure P is a prescribed value Pa or lower, a function generator 502 outputs corrected rotating speed Ns. A value obtained by subtracting the corrected rotating speed Ns from the target rotating speed Nt is outputted as a target rotating speed command value Ny to control engine rotating speed to the target rotating speed command value Ny.
