摘要： A system and method for controlling an environmentally-friendly vehicle perform a safety function by blocking a high voltage output of a high voltage battery at the time of a rear-lateral side collision of the environmentally-friendly vehicle. The high voltage blocking function is smoothly performed at the time of the rear-lateral side collision accident by determining a rear-lateral side collision of the environmentally-friendly vehicle using a blind spot detection sensor, a lane change alert sensor, or a rear cross traffic alert sensor, along with a yaw rate sensor that detects a yaw rate, and turning off a relay of the high voltage battery at a moment when the rear-lateral side collision is determined.
