Hand-leaving detection device for steering wheel, steering wheel and vehicle

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 a
