The invention provides an automatic driving vehicle control system and a redundancy control system, and belongs to the technical field of automatic driving vehicle safety. An AEBS system which is not coherent with an existing automatic driving sensor and an existing automatic driving controller of a vehicle is adopted, and the AEBS system comprises the AEBS controller and the AEBS sensor; when the automatic driving sensor or the automatic driving controller of the vehicle breaks down, the AEBS controller judges whether the vehicle has a collision risk or not according to data obtained by the AEBS sensor, and when the collision risk exists, the AEBS controller issues a braking request to achieve vehicle braking control. According to the invention, the AEBS system can work normally and detect possible collision in real time under the condition that the vehicle is out of control due to the failure of the original vehicle sensor or the failure of the automatic driving controller and the failure of effective recognition of obstacles in the environment or the failure of normal communication with the vehicle; and the vehicle can be controlled to perform emergency braking in time before the collision occurs, so that the safety performance of vehicle operation is improved.
本发明提出一种自动驾驶车辆控制系统和冗余控制系统,属于自动驾驶车辆安全技术领域。本发明采用一套与车辆已有自动驾驶传感器和自动驾驶控制器互不相干的AEBS系统,包括AEBS控制器和AEBS传感器;在车辆自动驾驶传感器或自动驾驶控制器出现故障时,AEBS控制器根据AEBS传感器获取的数据判断车辆是否存在碰撞风险,当存在碰撞风险时,AEBS控制器下发制动请求实现车辆制动控制。本发明保证了在原有车辆传感器故障或者自动驾驶控制器故障导致无法有效识别环境中障碍物或者无法和车辆正常通信而导致车辆失去控制的情况下,AEBS系统可以正常工作,实时探测可能发生的碰撞,并能够在碰撞发生前及时控制车辆进行紧急制动,提升了车辆运行的安全性能。
