Driver assistance system and safety monitoring unit and method thereof

The invention provides a driver assistance system and a safety monitoring unit and method thereof. The safety monitoring unit includes: an acquisition module configured to acquire a first line shape and a second line shape measured by two independent sensor devices and representing a shape of a same target line of a road on which a vehicle travels; a calculation module configured to calculate a difference between the first line shape and the second line shape; a determination module configured to determine whether there is a fault in the driver assistance system based on a comparison result between the calculated difference and a comparison threshold; and a generation module configured to generate a safety response command for triggering a safety response if it is determined that there is a fault in the driver assistance system. 提供了驾驶员辅助系统及其安全性监控单元和方法。所述安全性监控单元包括：获取模块，配置成获取第一线形和第二线形，所述第一线形和第二线形由两个独立的传感器设备测量并表示车辆行驶道路的同一目标线的形状；计算模块，配置成计算所述第一线形与所述第二线形之间的差；确定模块，配置成基于计算出差与比较阈值之间的比较结果来确定所述驾驶员辅助系统中是否存在故障；以及生成模块，配置成在
