The invention relates to a steering wheel with a hand-leaving detection function and a steering wheel system.The steering wheel comprises a framework and a processor; the framework is coated with a coating layer; a plurality of double-layer resistance film sheets are distributed on the coating layer; each double-layer resistance film sheet comprises an insulating layer, a first conductive layer and a second conductive layer; the insulating layer wraps the first conductive layer and the second conductive layer, a spacing layer is arranged between the first conductive layer and the second conductive layer, a first voltage is applied to the first conductive layer, and a second voltage is applied to the second conductive layer; and the processor is respectively connected with the first conductive layer and the second conductive layer of each double-layer resistance film sheet, and is used for determining a hand leaving detection result by utilizing the voltage change of the first voltage and the second voltage when a person holds the steering wheel by hand and the spacing layer is extruded to enable the first conductive layer to be in contact with the second conductive layer. According to the invention, the problem of low recognition accuracy due to possible misjudgment caused by bumpy road conditions is solved, the structure is simple, and the recognition accuracy is improved.
