| 摘要 | A method for controlling an auto idle state of heavy construction equipment of an exemplary embodiment of the present disclosure includes: storing, by a vehicle controller (VCU) that receives engine actuation information from an engine controller (ECU), an average traveling value of a worker-set engine RPM for a first set time when the heavy construction equipment is actuated at the worker-set engine RPM; and actuating, by the engine controller (ECU) that receives information on the average traveling value of the worker-set engine RPM for the first set time from the vehicle controller (VCU), an engine at a variable auto idle engine RPM, which varies depending on the average traveling value of the worker-set engine RPM for the first set time, when work is temporarily stopped and the worker-set engine RPM is switched to an auto idle engine RPM. | ||

| 主权项 | 1. A method for controlling an auto idle state of heavy construction equipment, comprising: storing, by a vehicle controller (VCU) that receives engine actuation information from an engine controller (ECU), an average traveling value of a worker-set engine RPM for a first set time when the heavy construction equipment is actuated at the worker-set engine RPM; and calculating a variable auto idle engine RPM changed depending on the average traveling value of the worker-set engine RPM for the first set time and actuating an engine at the variable auto idle engine RPM when work is stopped for a previously set predetermined time. | ||
