SYSTEM AND METHOD OF CONTROLLING VEHICLE OF CONSTRUCTION EQUIPMENT

摘要

The present disclosure relates to a system and method of controlling a vehicle of construction equipment, which calculate a target engine torque from compensation torque information using torque information generated in a hydraulic pump and an engine speed error and transmit the calculated target engine torque, thereby more stably performing engine control while responding to a rapid load variation of the hydraulic pump.

主权项

1. A system for controlling a vehicle of construction equipment, comprising:
an engine; a hydraulic pump operated by power supplied from the engine; one or more actuators driven by a hydraulic pressure discharged from the hydraulic pump; a hydraulic pump control device configured to calculate a compensation torque according to a hydraulic pump torque and an engine speed error between an actual engine RPM and a target engine RPM, compensate for the calculated hydraulic pump torque with the calculated compensation torque, and output the compensated torque as a target engine torque; and an engine control unit configured to control a torque of the engine based on the output target engine torque.
