APPARATUS AND METHOD FOR CONTROLLING VEHICLE OF CONSTRUCTION EQUIPMENT
An embodiment of the present specification relates to a system and a method for controlling a vehicle of construction equipment. The system and the method can calculate and transmit a target engine torque calculated from compensation torque information which uses both torque information generated in a hydraulic pump and an engine speed error. Therefore, the system and the method for controlling a vehicle of construction equipment can respond to sudden load changes in the hydraulic pump and can control an engine stably. In addition, the system comprises: an engine; a hydraulic pump which is operated by power supplied from the engine; at least one actuator which is driven by hydraulic pressure discharged from the hydraulic pump; a hydraulic pump control device which calculates a hydraulic pump torque and a compensation torque according to an engine speed error between an actual engine RPM and a target engine RPM, compensates the calculated hydraulic pump torque with the calculated compensation torque, and outputs the result as an engine target torque; and an engine control unit which controls engine torques based on the outputted engine target torque.
본 명세서의 일부의 실시 예는 건설기계의 차량 제어 시스템 및 방법에 관한 것으로, 유압펌프에서 발생하는 토크 정보와 엔진 속도 오차를 이용한 보상 토크 정보로부터 엔진 목표 토크를 계산하여 송신함으로써, 유압펌프의 급격한 부하 변동에 대응하면서 더 안정적으로 엔진 제어를 수행할 수 있는 건설기계의 차량 제어 시스템 및 방법을 제공할 수 있다.
