A method for controlling coasting drive of an environmentally friendly vehicle comprises: a step of calculating a coasting speed of an environmentally friendly vehicle at a reducing event point based on a target coasting distance to a reducing event and an inclination degree of the reducing event point by a controller; a step of calculating a control target speed of the environmentally friendly vehicle based on a target speed of the environmentally friendly vehicle at the reducing event point and the calculated a coasting speed by the controller; and a step of controlling to output control torque in a powertrain of the environmentally friendly vehicle, wherein the control torque adjusts the speed of the environmentally friendly vehicle to the target speed based on the calculated target speed by the controller.
친환경 차량의 타행 주행 제어 방법은, 제어기가 감속 이벤트까지의 목표 타행거리 및 감속 이벤트 지점의 경사도에 근거하여 감속 이벤트 지점에서의 친환경 차량의 타행속도를 계산하는 단계와, 제어기가 감속 이벤트 지점에서의 친환경 차량의 목표 속도와 상기 계산된 타행속도에 근거하여 친환경 차량의 제어 목표 속도를 계산하는 단계와, 제어기가 상기 계산된 제어 목표 속도에 근거하여 친환경 차량의 속도를 목표 속도로 조정하는 제어 토크를 친환경 차량의 파워트레인에 출력하도록 제어하는 단계를 포함한다.
