The invention belongs to the technical field of automobile steering wheel HOD application, and particularly discloses an automobile steering wheel HOD monitoring system which comprises a gateway, an LIN communication module, a main control module and an HOD sensor. The gateway, the LIN communication module, the main control module and the HOD sensor are connected in sequence, and the gateway is connected with the ADAS system. According to a capacitive detection and torque signal two-in-one scheme, 1) not only the problem of misjudgment of EPS on a bumpy road surface is solved, but also HOD signals are fused according to the torque signals, and the problems that a capacitive sensing scheme has a fuzzy judgment area in a multi-fingered application occasion and cannot accurately identify an HOD state is overcome; and 2, the problem that a traditional HOD scheme cannot recognize various driver operation gestures is solved through internal algorithm analysis and a steering wheel capacitance detection layout mode, the control ability of a current driver to a steering wheel is accurately recognized, and the driving experience is improved.

    本发明属于汽车方向盘HOD应用技术领域,具体公开了汽车方向盘HOD监测系统,包括网关、LIN通信模块、主控模块和HOD传感器;所述网关、LIN通信模块、主控模块、HOD传感器依次连接,其中,网关与ADAS系统连接。1、电容式检测和扭矩信号二合一方案,既解决了EPS在颠簸路面误判的问题,同时又能根据扭矩信号对HOD信号进行融合,解决电容感应方案在多指的应用场合存在的模糊判断的区域,未能准确识别出HOD状态问题;2:电容式检测和扭矩信号二合一方案,通过内部的算法分析和方向盘电容检测布局方式,解决了传统HOD方案不能识别多种驾驶员操作手势问题,精确识别出当前驾驶员对方向盘掌控能力,提高驾驶体验。
