The invention relates to the technical field of automobiles, discloses a steering wheel hand-leaving detection device, a steering wheel and a vehicle, and solves the problem that the existing steering wheel hand-leaving detection cannot determine whether one hand leaves the hand or both hands leaves the hand and which hand leaves the hand. The steering wheel hand-leaving detection device comprises a first electric conductor, a second electric conductor, a third electric conductor, a fourth electric conductor and a control unit, wherein the first electric conductor and the second electric conductor are arranged inside a steering wheel framework; the opposite parts of the first conductor and the third conductor form a first capacitor, the opposite parts of the second conductor and the fourth conductor form a second capacitor, and the control unit judges which hand of a user is in a hand-off state or two hands are in the hand-off state at the same time according to the capacitance change of the first capacitor and the second capacitor.

    本申请涉及汽车技术领域,公开了一种方向盘离手检测装置、方向盘和车辆,解决现有方向盘离手检测无法确定是单手离手还是双手离手以及哪只手离手的问题。该方向盘离手检测装置设置于方向盘骨架内部的第一和第二导电体、设置于方向盘骨架外部的第三和第四导电体和控制单元;该第一导电体和该第三导电体的相对部分形成第一电容,该第二导电体和该第四导电体的相对部分形成第二电容,控制单元根据该第一和第二电容的电容量变化判断用户哪只手处于离手状态或两只手同时处于离手状态。
