The invention relates to a steering wheel out-of-hand detection method and device, a readable storage medium and a vehicle, and relates to the field of automatic driving. The method comprises the steps of periodically obtaining capacitance values collected by a capacitance sensor aiming at a vehicle steering wheel; acquiring a torque value acquired by a torque sensor aiming at the steering wheel; periodically determining a capacitance value variation according to the capacitance value and a preset capacitance reference value; and when the capacitance value variable quantity is smaller than a preset capacitance value variable quantity threshold value and the working state of the capacitance sensor is not in an effective state, determining a hand release detection result according to the working state of the capacitance sensor and the torque value. Thus, even in some special use scenes, whether the steering wheel slips out of the hand or not can be accurately detected, accurate information is provided for an auxiliary driving system, and the driving safety is improved.
