The invention discloses a safety redundancy system for automatic driving in an engineering park, and the system is characterized in that the system comprises a chassis controller which is located in an automatic driving vehicle and is used for receiving a control instruction and controlling a drive-by-wire device in the automatic driving vehicle according to the control instruction; the emergency stop switches are distributed in all stop stations in the engineering park, and wireless communication connection is established between the emergency stop switches and the chassis controller when the distance between the emergency stop switches and the chassis controller is within a preset range; when the chassis controller communicates with the emergency stop switch, the state of the emergency stop switch is monitored, and when the emergency stop switch is triggered, the chassis controller controls a drive-by-wire device in the automatic driving vehicle to conduct braking. According to the technical scheme provided by the invention, a safety redundancy scheme for a station coordination scene is realized, and the safety of automatic driving in an engineering park is improved.
本发明公开了一种工程园区内自动驾驶的安全冗余系统,其特征在于,系统包括:底盘控制器,底盘控制器位于自动驾驶车辆中,用于接收控制指令,并根据控制指令控制自动驾驶车辆中的线控装置;紧急停车开关,紧急停车开关分布于工程园区内的各个停靠站点中,且与底盘控制器的距离在预设范围内时与底盘控制器建立无线通信连接;其中,底盘控制器在与紧急停车开关通信时,监测紧急停车开关的状态,当紧急停车开关被触发时,底盘控制器控制自动驾驶车辆中的线控装置进行制动。本发明提供的技术方案,实现了针对车站协同场景的安全冗余方案,提高了工程园区内自动驾驶的安全性。
