The invention discloses an automobile collision avoidance system for vulnerable road users and a control method thereof, and relates to the field of vehicle driving safety. A decision module receives information collected by a sensing module and makes a corresponding scheme, and an execution module is used for executing the scheme of the decision module; the decision module receives the automobile motion information, the motion information of surrounding targets and the road condition information acquired by the sensing module, judges whether a dangerous target exists or not, determines a collision avoidance scheme after evaluating the feasibility of active braking and active steering, and calculates the expected braking pressure, the expected throttle opening and the expected steering wheel turning angle; the execution module is based on a control signal of the decision module, when the automobile is actively braked, a brake and a throttle valve controller work cooperatively, and braking deceleration is output; and when the automobile actively steers, the steering system enables the automobile to steer along the planned path. Active braking or active steering operation is adopted, collision between the automobile and a dangerous target is avoided to the maximum extent, and therefore the road safety is remarkably improved.
本发明公开了一种针对弱势道路使用者的汽车避撞系统及其控制方法,涉及车辆行驶安全领域,决策模块接收感知模块采集到的信息并做出相应的方案,执行模块用来执行决策模块的方案;决策模块接收感知模块获取的汽车运动信息、周围目标的运动信息和路况信息,判断是否存在危险目标再评估主动制动和主动转向的可行性后确立避撞方案,计算期望制动压力、期望节气门开度和期望方向盘转角;执行模块基于决策模块的控制信号,当汽车主动制动时,制动器与节气门控制器协同工作,输出制动减速度;当汽车主动转向时,转向系控制汽车沿规划路径转向行驶。本发明采取主动制动或主动转向操作,最大限度地避免汽车与危险目标发生碰撞,从而显著提高了道路安全性。
