The invention discloses an accident early warning system based on an intelligent networked automobile, particularly relates to the technical field of accident early warning, and realizes data interaction and transmission between the automobile and surrounding vehicles by collecting the driving states of the automobile and the surrounding vehicles in real time. And calculating the average speed and acceleration of surrounding vehicles through a weighted summation mode, and combining the average speed and acceleration with the data of the vehicle to obtain the speed and acceleration of the vehicle. Based on the information, the system calculates the safe distance to ensure that the safe distance is kept between the vehicle and the front vehicle. If the distance is smaller than the safe distance, the system sends out deceleration reminding. When the front vehicle is too close, the system predicts the driving tracks of the surrounding vehicles and the vehicle, simulates different turning angles and accelerations, and ensures that the vehicle does not collide with the surrounding vehicles. And if the avoidance turning is not feasible, the system simulates the collision momentum and the collision position in different obstacle avoidance modes, calculates a loss coefficient by using a logistic regression formula, and selects a risk avoidance path with the minimum loss, so that collision is effectively avoided.

    本发明公开了基于智能网联汽车的事故预警系统,具体涉及事故预警技术领域,本发明通过实时采集本车及周围车辆的行驶状态,并实现本车与周围车辆的数据交互与传输。通过加权求和的方式,计算周围车辆的平均速度与加速度,并与本车的数据结合,得出本车的速度与加速度。基于这些信息,系统计算安全距离,确保本车与前方车辆保持安全间距。若距离小于安全距离,系统会发出减速提醒。当前方车辆过近时,系统预测周围车辆与本车的行驶轨迹,模拟不同转弯角度与加速度,确保本车与周围车辆不发生碰撞。如果避让转弯不可行,系统通过模拟不同避障模式下的碰撞动量与碰撞位置,使用逻辑回归公式计算损失系数,选择损失最小的避险路径,从而有效避免碰撞。
