BEST DRIVING CONTROL METHOD OF EXCAVATOR |
摘要 |
The method for adapting the hydraulic vehicle to variously changing loads generated from a running motor according to the road conditions, switches the running mode from the primary step to the secondary step in order to offer efficient running. When the manipulating degree (&thgr;1) of the pedal (15) in running motors (6,8) is not zero, current value (Ia) for controlling the electromagnetic valve (10) and current value (Ib) for controlling the swash-plate angle adjusting valves (3b,4b) are calculated according to the degree (&thgr;1). When the degree (&thgr;1) is the maximum value (&thgr;max) the sensor (14) for detecting the operating velo city (V1) of the motors (6,8) outputs the current signal, the velocity (V1) is compared with the allowed low velocity (V2), and the solenoid valve (11) is operated for adjusting the swash-plate angle.
