The invention discloses a V2V-based pleasant front collision early warning system and early warning method, and belongs to the technical field of driving active early warning of intelligent networked vehicles. The system comprises an information acquisition module, an intention recognition parameter acquisition module, a control module and a man-machine interaction module which are connected in sequence. Firstly, different safety distance models are selected in advance through intention recognition of a vehicle and a front vehicle, rear-end collision situations under different working conditions are considered, the early warning distance can be calculated in a more targeted mode, and the applicability of an FCW system is improved; secondly, compared with front vehicle information obtained by a traditional perception sensor of a single vehicle intelligent system, the front vehicle information is obtained in a V2V mode, the accuracy of front vehicle intention recognition is guaranteed, the correctness of information such as the front vehicle speed, the acceleration and the relative distance in the early warning distance is guaranteed, and the correctness of an FCW system safety distance model is guaranteed.

    本发明公开了一种基于V2V的宜人化的前方碰撞预警系统及预警方法,属于智能网联汽车驾驶主动预警技术领域。包括有信息采集模块、意图识别参数获取模块、控制模块、人机交互模块,所述信息采集模块、意图识别参数获取模块、控制模块、人机交互模块依次连接。首先,本发明通过自车与前车的意图识别来提前选取不同的安全距离模型,考虑了不同工况的追尾碰撞情况,可以更有针对性的计算预警距离,提升FCW系统的适用性;其次,相对单车智能系统的传统感知传感器获取的前车信息,本发明通过V2V方式获取得到前车信息,保证了前车意图识别的准确率,保证了预警距离中前车车速、加速度、相对距离等信息的正确度,保证了FCW系统安全距离模型的正确性。
