The invention belongs to the technical field of transport trucks, and particularly relates to an automatic driving truck and an unmanned driving system. The automatic driving system is arranged in the whole vehicle chassis and used for generating a control intention according to a sensed external environment, the whole vehicle control system is used for controlling the whole vehicle chassis to execute the control intention, and a cargo carrying area is formed on the upper portion of the whole vehicle chassis; the whole vehicle control system comprises an EBS braking system, the automatic driving system forms a braking demand message through a braking control intention according to the required braking degree and transmits the braking demand message to the EBS braking system through a CAN network, and the EBS braking system responds to the braking control intention meeting the required braking degree according to the message content. According to the automatic driving truck, the braking demand message is transmitted to the EBS through the CAN network, mechanical actions are not needed in the control signal transmission process, the control process is number-number-execution, full digital control is achieved, the response delay of the braking system is smaller, the performance of the automatic driving truck is more excellent, and driving is safer.
本发明属于运输货车技术领域,具体涉及一种自动驾驶货车及无人驾驶系统。包括整车底盘,设置在整车底盘中的用于根据感知到的外部环境产生控制意图的自动驾驶系统,用于控制整车底盘以执行控制意图的整车控制系统,整车底盘上部形成载货区域;整车控制系统包括EBS制动系统,自动驾驶系统根据需求制动程度,将制动控制意图形成制动需求报文,通过CAN网络传输给EBS制动系统,EBS制动系统根据报文内容响应符合需求制动程度的制动控制意图。本发明的自动驾驶货车,通过CAN网络向EBS制动系统传递制动需求报文,控制信号传输过程不需要机械动作,控制过程为“数—数—执行”,实现全数字化控制,制动系统响应延时更小,使自动驾驶货车性能更优越,行驶更加安全。
