The invention discloses a system for triggering and controlling an automobile formation through periodic events. The system comprises a front-end vehicle-mounted radar, a rear-end vehicle-mounted radar, an intelligent network connection controller and a driving/braking controller. The front-end vehicle-mounted radar is used for sensing the relative position and the relative speed of the front vehicle and receiving the motion state information of the front vehicle; the intelligent network connection controller is a main control module for formation driving and makes a decision through a built-in algorithm according to input; the driving/braking controller is used for executing the decision of the intelligent network connection controller; and the rear-end vehicle-mounted radar is used for sending the motion state information of the vehicle. The radar in the system has a sensing function and a reliable wireless communication function at the same time, and follows a periodic sampling and event triggering mechanism and a working scheme thereof. The stability of the formation system is ensured. Compared with the prior art, hardware cost is reduced, and communication resources are saved.
本发明公开了一种周期性事件触发控制汽车编队的系统,包括前端车载雷达、后端车载雷达、智能网联控制器、驱动/制动控制器。前端车载雷达用于感知与前车的相对位置、相对速度和接收前车运动状态信息;所述智能网联控制器是编队行驶的主控模块,根据输入通过内置算法做出决策;所述驱动/制动控制器用于执行智能网联控制器的决策;所述后端车载雷达用于属于发送自车的运动状态信息。本系统中雷达同时具备感知功能和可靠的无线通信功能,并遵循周期采样、事件触发机制及其工作方案。即保证编队系统稳定性。与现有技术相比,降低了硬件成本,节约通信资源。
