A method for controlling coasting drive of an environmentally friendly vehicle comprises the following steps of: determining, by a controller, a deceleration target speed of the environmentally friendly vehicle based on a forward deceleration event of the environmentally friendly vehicle; determining, by the controller, a correction value of a charging limit amount to prevent a charging limit with respect to a battery based on a charging accumulation amount with respect to the battery in accordance with the charging limit amount with respect to the battery supplying electricity to a drive motor of the environmentally friendly vehicle and the forward deceleration event; and controlling, by the controller, the environmentally friendly vehicle with the deceleration target speed by performing hydraulic braking of the environmentally friendly vehicle based on the charging amount of the battery by the drive motor and the correction value of the charging limit amount.
친환경 차량의 타행 주행 제어 방법은, 제어기가 상기 친환경 차량의 전방 감속 이벤트에 근거하여 상기 친환경 차량의 감속 목표 속도를 결정하는 단계와, 상기 제어기가 상기 친환경 차량의 구동 모터에 전력을 공급하는 배터리에 대한 충전 제한량과 상기 전방 감속 이벤트에 따른 상기 배터리에 대한 충전 누적량에 근거하여 상기 배터리에 대한 충전제한을 방지하는 값인 상기 충전 제한량의 보정값을 결정하는 단계와, 상기 제어기가 상기 구동 모터에 의한 배터리의 충전량과 상기 충전 제한량의 보정값에 근거하여 상기 친환경 차량의 유압 제동을 수행시켜 상기 친환경 차량을 상기 감속 목표 속도로 제어하는 단계를 포함한다.
