The invention discloses an emergency control method for responding to sudden lane changing of a side lane vehicle during fatigue driving and belongs to the field of automobiles. When a front arranged vehicle detector detects sudden lane changing of the vehicle on a side lane, a front arranged distance measurement module detects the distance between a vehicle body and the lane changing vehicle and compares the distance with the braking distance obtained through conversion with a conversion table of driving speed and braking distance. When the braking distance is larger than the measured distance, a front arranged speed measurement module conducts speed measurement on the lane changing vehicle and compares the speed of the lane changing vehicle with the current speed of the vehicle body. When the measured speed is smaller than the speed of the vehicle body, a rear arranged vehicle detector detects whether a vehicle is on side lanes of the lane of vehicle body, lane changing is conducted towards the lane where no vehicle is located. If vehicles are on both two lanes, a rear arranged speed measurement module measures the speed of the vehicles on the side lanes, lane changing is conducted towards the lane where the vehicle speed is smaller than the speed of the vehicle body, or an auxiliary braking system conducts auxiliary braking in time. The emergency control method is mainly used for the condition of sudden lane changing of the side lane vehicle during fatigue driving, the vehicle body can be controlled in real time, and thus traffic accidents are reduced effectively.
