The invention relates to the technical field of vehicle variable control, and discloses a driving environment sensing method and system for an autonomous vehicle, and the system comprises a vehicle driving road environment state collection module, a vehicle driving road environment state sensing module, and a vehicle driving road environment state emergency processing module. Vehicle driving speed data and front object speed data are accurately collected through a speed sensor, and the driving motion states of a driving vehicle and a front object are conveniently and accurately monitored through the speed of the driving vehicle and speed parameters of the front object; a distance sensor is used for collecting distance parameters from a driving measurement distance to a front object, vehicle side distance parameters of a driving vehicle and distances from the front side and the rear side of the driving vehicle to an adjacent road object on line, so that the driving position relation between the driving vehicle and the front object is scientifically analyzed, and danger characteristics of the driving environment of the driving vehicle are sensed.

    本发明涉及车辆变量控制的技术领域,且公开了一种自动驾驶车辆的行驶环境感知方法及系统,该系统包括车辆行驶道路环境状态采集模块、车辆行驶道路环境状态感知模块、车辆行驶道路环境状态应急处理模块;通过速度传感器精确采集车辆行驶速度数据和前方物体速度数据,利用行驶车辆自身速度和前方物体速度参数,便于精确监测行驶车辆与前方物体行驶运动状态;使用距离传感器在线采集行驶测量距离前方物体的距离参数、行驶车辆车侧距离参数、行驶车辆前后方两侧到相邻道路物体的距离便于科学分析行驶车辆与前方物体的行驶位置关系和感知行驶车辆行驶环境的危险特征。
