The invention discloses a braking anti-lock control method and device and a vehicle, and is applied to the technical field of braking anti-lock control. The method comprises the steps that the vehicle is controlled to trigger a braking anti-lock function; under the condition that the vehicle triggers a braking anti-lock function, at least two times of pressure increasing and reducing cycle control are performed on the vehicle so that the vehicle can be stopped, and each pressure increasing and reducing cycle control comprises pressure reducing control and pressure increasing control after the pressure reducing control. In the first-time pressure increasing and reducing cycle control, the pressure reducing control is executed under the condition that the slip rate of the vehicle is larger than a first slip rate threshold, and in the non-first-time pressure increasing and reducing cycle control, the pressure reducing control is executed after the pressure increasing control of the previous-time pressure increasing and reducing cycle control and under the condition that the slip rate of the vehicle is larger than a second slip rate threshold. The second slip rate threshold is smaller than the first slip rate threshold. According to the application, the triggering precision and the control precision of the anti-lock braking function are improved.
