SYSTEM AND METHOD FOR CONTROLLING ENVIRONMENTALLY-FRIENDLY VEHICLE

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.

1. A system for controlling an environmentally-friendly vehicle, the system comprising:
a rear-lateral side detection sensor configured to detect an expected collision time with and a distance from a collision object; and a controller configured to determine that a rear-lateral side collision and block a connection of a relay of a battery of the vehicle when the expected collision time detected by the rear-lateral side detection sensor is equal to or smaller than a first threshold value and a distance from the collision object detected by the rear-lateral side detection sensor is equal to or smaller than a second threshold value.
