The invention discloses an automatic driving function degradation processing device which is characterized in that a plurality of cameras, a millimeter wave radar, a laser radar, a vehicle-mounted navigation system, a vehicle positioning system, an automatic driving control system and an execution system are arranged on a vehicle body, the automatic driving control system and the execution system are electrically connected, and a control system main chip and a standby chip which are connected in parallel are arranged in the control system; two sets of steering structures and two sets of braking structures are arranged in the execution system, the first set of steering structures and the first set of braking structures are electrically connected with the control system main chip and controlled by the control system main chip, and the second set of steering structures and the second set of braking structures are electrically connected with the control system standby chip and controlled by the control system standby chip. According to the device, the main chip and the standby chip of the control system and two sets of steering structures and braking structures are arranged and are mutually redundant, and when an automatic driving system or related hardware breaks down, degradation logic is entered through redundant hardware, so that low-level automatic driving is entered, and the life and property safety of drivers and passengers is guaranteed.

    本发明公开了自动驾驶功能降级处理装置,在车身上设置多个摄像头、毫米波雷达、激光雷达,车载导航系统,车辆定位系统,电连接的自动驾驶控制系统和执行系统,在控制系统内,设置有并联的控制系统主芯片和备用芯片,执行系统内设置的转向结构和制动结构都是两套,第一套转向结构和制动结构与控制系统主芯片电连接,受控制系统主芯片控制,第二套转向结构和制动结构与控制系统备用芯片电连接,受控制系统备用芯片控制。本发明的装置,设置了控制系统主芯片和备用芯片,以及两套转向结构和制动结构,互为冗余,在自动驾驶系统或相关硬件产生故障时,通过冗余硬件进入降级逻辑,从而进入低级别的自动驾驶,保障驾乘人员的生命财产安全。
