The invention discloses a steering wheel capable of warning a driver of fatigue driving. The steering wheel comprises a steering wheel supporting rack, an angular speed sensor is fixedly arranged at the center of the steering wheel supporting rack, and a plurality of pressure sensors which are sequentially in series connection are fixedly arranged on a handrail of the steering wheel supporting rack in the circumferential direction. A fatigue driving warning device is further fixedly arranged on the steering wheel supporting rack, and the fatigue driving warning device comprises a shell. A single chip microcomputer, a warning flashing light and a warning loudspeaker are arranged in the shell, and the shell is further provided with a shutoff button which can be used for turning off the warning flashing light and the warning loudspeaker. The angular speed sensor and the pressure sensors are connected with the input end of the single chip microcomputer, and the warning flashing light and the warning loudspeaker are connected with the output end of the single chip microcomputer. According to the steering wheel, the fatigue driving of the driver is effectively warned on the basis of the detection operation frequency and gripping force (or pressure), operation is easy, and high practicability and realizability are achieved.
