An elevator control method and device, an elevator, a readable storage medium and a program product. The elevator (100) comprises a motor (20) and a car (30), the motor (20) being connected to the car (30). The method comprises: acquiring the moving speed of the car (30), the moving speed being positively correlated with the rotation speed of the motor (20); and in response to an elevator braking scenario, when the moving speed is less than or equal to a preset short winding braking threshold, starting a short winding braking function to brake the car (30), the short winding braking function being configured to be started when three phases of the motor (20) are short-circuited. Therefore, when the elevator needs to be braked and the moving speed of the car (30) is less than or equal to the preset short winding braking threshold, the three phases of the motor (20) can be short-circuited, so as to start the short winding braking function for braking, and avoid excessive loss of a brake pad of a brake (50). Meanwhile, because the short winding braking function is started only when the moving speed is smaller than or equal to the preset short winding braking threshold, long-time operation of the short winding braking function can be avoided, thereby ensuring as much as possible normal operation of devices used for achieving the short winding braking function.
