The invention discloses a driver hand release detection method, device and equipment and a storage medium, and relates to the technical field of vehicle control, and the driver hand release detection method comprises the steps that a torque detection value and a capacitance parameter of a steering wheel are obtained; estimating a real direction torque input by a driver according to the torque detection value to obtain a reference torque; obtaining a driving state according to the capacitance parameter and the reference torque, wherein the driving state comprises normal driving and hand-free driving; according to the method, the detection torque of the steering wheel is obtained through a detector, interference signals of the torque detection value of the steering wheel are further eliminated, accurate reference torque capable of better representing the input torque of a driver is extracted, and whether the driver drives without hands is comprehensively judged from multiple angles by combining contact capacitance signals of the driver at the steering wheel. And the accuracy of judging the hand release of the driver is effectively improved.
