The invention discloses a steering wheel with a driver grip strength detection function and a method, and belongs to the technical field of intelligent driving. Comprising a grip strength sensor used for generating displacement and providing grip strength information when a driver holds a steering wheel; the temperature sensor is used for detecting the temperature of the steering wheel at the held position of the steering wheel main body; and the steering wheel controller is connected with the grip strength sensor and the temperature sensor and is used for judging whether a driver holds the steering wheel or not according to the grip strength information, the steering wheel temperature, the cab temperature and the environment temperature. The technical scheme has the beneficial effects that due to the adoption of the technical scheme, the problem of misjudgment in a drive-by-wire mode of the electric power steering controller is effectively solved, and the problem that whether the steering wheel is manually held or not cannot be distinguished under a lane keeping function is effectively solved.
