Washing machine control method and washing machine

The invention provides a washing machine control method and a washing machine, and the control method comprises the steps: presetting allowance time delta in a control module, in the washing process, obtaining current washing preset time T0 and real-time washing target time T1 in real time, and calculating error time delta T through the following formula: delta T = current washing preset time T0-real-time washing target time T1, moreover, when delta T is less than-delta, the control module outputs a control signal to enhance the washing strength; when delta T is larger than or equal to-delta and smaller than or equal to delta, the existing washing state is kept unchanged; when delta T is larger than delta, the value of the current washing preset time T0 is replaced with the value of the real-time washing target time T1, the PID control algorithm is adopted for control, and adjustment of the washing process time of the washing machine is more accurate. According to the method, the target washing time is determ
