A self-adaptive cruise control system based on brake-by-wire is composed of a data acquisition module, a self-adaptive cruise mode switching module, an execution unit and a driving ECU, and the data acquisition module, the self-adaptive cruise mode switching module and the execution unit are connected with the driving ECU through a CAN bus. The driving ECU receives signals of the data acquisition module and transmits the signals to the self-adaptive cruise mode switching module, and the self-adaptive cruise mode switching module calculates the safety distance so as to switch to a proper control mode and perform self-adaptive cruise on the vehicle through the driving ECU and the execution unit. According to the system, self-adaptive cruise during intelligent driving is achieved, the self-designed mode switching method solves the problems of frequent control mode switching of an intelligent driving vehicle in the self-adaptive cruise process and control incoherence, comfort and economy are both considered. Meanwhile, a driving safety distance control method is designed to improve the adaptability of different external environments such as rainy days and nights, and emergencies in severe weather are prevented.
一种基于线控制动的自适应巡航控制系统,由数据采集模块、自适应巡航模式切换模块、执行单元、行车ECU组成,数据采集模块、自适应巡航模式切换模块、执行单元均通过CAN总线连接行车ECU;行车ECU接受数据采集模块的信号,并传输给自适应巡航模式切换模块,自适应巡航模式切换模块进行安全距离的计算,以此切换至合适的控制模式并通过行车ECU以及执行单元对自车进行自适应巡航。本系统实现智能驾驶时的自适应巡航,自行设计的模式切换方法解决智能驾驶车辆在自适应巡航的过程中频繁的控制模式切换,以及出现的控制的不连贯问题,以兼顾舒适性和经济性,同时设计行车安全距离控制方法来提高雨天、夜晚等不同外界环境的适应性,防止恶劣天气下的突发情况。
