Emergency control method for responding to sudden lane changing of side lane vehicle during fatigue driving

Abstract

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.

Description

technical field [0001] The invention relates to an emergency control method for sudden lane changes of vehicles in the traffic field, in particular to an emergency control method for coping with sudden lane changes of bypass vehicles during fatigue driving. Background technique [0002] Today, with the continuous development of the economy, the number of private cars is increasing, so the frequency of traffic accidents is gradually increasing. According to the data of a highway safety investigation agency, about 70% of traffic accidents are caused by vehicles changing lanes. Part of the reason is that the driver was distracted due to fatigue driving, and did not notice that a vehicle in front suddenly changed lanes and drove into his lane, which may cause traffic accidents. Therefore, it is urgent to design an emergency control method to reduce the frequency of such traffic accidents. [0003] Generally speaking, if the driver is paying attention, then the driver will gener...

[0004] Chinese patent CN201210079084.3 discloses an automobile auxiliary braking system that is easy to operate and reduces tire wear. When braking, the deceleration fluid sprayed from the liquid spray pipe adheres to the wheels and the ground, increasing the friction coefficient between the wheels and the ground. The braking distance is shortened. The prerequisite for these auxiliary braking is that the driver should step on the brake pedal. However, when the driver is tired, the attention may not be very concentrated, and traffic accidents are very likely to occur
