The invention relates to the technical field of automatic driving control, in particular to an automatic driving container truck open circuit protection system for a port, which comprises a truck body and a protection system arranged on the truck body and used for realizing open circuit protection, and a parking hand valve, a differential valve and a rear axle brake chamber are arranged in the protection system. A second electromagnetic valve and an eight-hole valve are arranged between the parking hand valve and the rear axle braking air chamber, a relay is arranged in the second electromagnetic valve, a trailer hand valve is further arranged in the protection system, and a trailer valve is assembled on one side of the trailer valve. During power failure, the relay in the second electromagnetic valve trips automatically, the relay in the second electromagnetic valve can check an ADU signal through the VCU/EBS, when the ADU signal is wrong or lost, the relay in the second electromagnetic valve is powered off, the second electromagnetic valve immediately triggers active braking, and the relay in the second electromagnetic valve is powered off. And the safety of the vehicle is actively protected, and automatic parking can be immediately started when the vehicle is accidentally powered off or an ADU signal is wrong.
本发明涉及自动驾驶控制技术领域,具体为一种港口用自动驾驶集装箱卡车断路保护系统,包括卡车本体和设置在卡车本体上用以实现断路保护的保护系统,保护系统内部驻车手阀、差动阀和后桥制动气室,驻车手阀与后桥制动气室间设有第二电磁阀,以及八孔阀,第二电磁阀内设有继电器,保护系统内部还设有挂车手阀,挂车阀一侧装配有挂车阀,本发明通过在挂车制动的挂车手阀与挂车阀间加一个第二电磁阀,断电时第二电磁阀内的继电器发生自动跳闸,第二电磁阀内的继电器可通过VCU/EBS校验ADU信号,当ADU信号错误或者丢失后,第二电磁阀中继电器断电,第二电磁阀立即触发主动制动,主动保护车辆安全有效实现车辆在意外断电或ADU信号错误时的立即启动自动驻车。
