The invention relates to a steering wheel assembly, a vehicle having the steering wheel assembly and a method for checking a skeleton connection in the steering wheel assembly. The invention relates to a steering wheel assembly (1) for a vehicle, comprising a steering wheel device (2), the steering wheel device (2) having a steering wheel skeleton (3), a first electrically conductive layer (6) and a second electrically conductive layer (8), an intermediate layer capacitor CLayer (12) being formed between the first electrically conductive layer (6) and the second electrically conductive layer (8), wherein a skeleton capacitance CSketon is formed between the second electrically conductive layer (8) and the steering wheel skeleton (3), the steering wheel skeleton (3) can be coupled and/or coupled to a ground connection M of the vehicle via a skeleton connection (13), and wherein the intermediate layer capacitance CLayer (12) and the skeleton capacitance CSketon form a capacitive voltage divider for a voltage applied to the first electrically conductive layer (6), wherein a partial voltage can be tapped on the second electrically conductive layer (8), and the steering wheel assembly has an evaluation device (16), the evaluation device (16) being designed to detect a partial voltage on the second electrically conductive layer (8) and to determine whether the skeleton connection (13) is normal or abnormal on the basis of the detected partial voltage.

    本发明涉及一种方向盘组件、一种具有所述方向盘组件的车辆以及一种用于检查在所述方向盘组件中的骨架连接的方法。提出一种用于车辆的方向盘组件(1),所述方向盘组件包括方向盘装置(2),其中所述方向盘装置(2)具有方向盘骨架(3),第一导电层(6)和第二导电层(8),其中在所述第一导电层(6)与所述第二导电层(8)之间构造有中间层电容C_Layer_(12),其中在所述第二导电层(8)与所述方向盘骨架(3)之间构造有骨架电容C_Skeleton,其中所述方向盘骨架(3)通过骨架连接(13)与所述车辆的接地M可耦联和/或耦联,其中中间层电容C_Layer_(12)和骨架电容C_Skeleton形成用于施加在所述第一导电层(6)上的电压的电容分压器,其中在第二导电层(8)上能分接出分电压,并且所述方向盘组件具有评估装置(16),其中所述评估装置(16)构造用于检测所述第二导电层(8)上的分电压,并且基于所检测的分电压判断所述骨架连接(13)为正常或不正常。
