The invention provides a driving risk monitoring method for an emergent target, and belongs to the field of intelligent driving. The monitoring method comprises the following steps: acquiring historical environment data associated with an emergent target, establishing an emergent target impulse traversal model, and predicting the probability of emergent target impulse traversal; the driving risk field is constructed by combining the emergent target impulse passing probability and other state information of the intelligent vehicle, and the driving risk is judged according to the value of the driving risk field. According to the method, the driving risk field is constructed, the risk threshold value of safe driving of the intelligent vehicle is provided, once the driving risk field value of the intelligent vehicle exceeds the risk field threshold value, the intelligent vehicle can give out an early warning prompt, and collision accidents occurring when an emergent target travels in an impulsive mode in a visual blind area environment are effectively avoided.
本发明提出一种针对突现目标的行车风险监测方法,属于智能驾驶领域。所述监测方法包括:获取与突现目标相关联的历史环境数据,并建立突现目标冲动性穿行模型,预测突现目标冲动性穿行的概率;通过结合突现目标冲动性穿行概率和智能车辆其他状态信息构建行车风险场,并根据行车风险场场值判断行车风险。本发明通过构建行车风险场,提供了智能车辆安全行驶的风险阈值,一旦智能车辆的行车风险场值超过风险场阈值,智能车辆就会发出预警提示,有效避免视觉盲区环境中突现目标出现冲动性穿行时发生碰撞事故。
