The embodiment of the invention provides a vehicle braking method, device and equipment and a computer storage medium, the vehicle braking method comprises the steps that the slip rate, the required braking force and the mechanical braking force of a vehicle and the feedback braking force and the maximum feedback braking force of a motor are obtained, and the slip rate is obtained through calculation based on the wheel speed and the vehicle speed of the vehicle; when it is detected that the slip rate of the vehicle is smaller than or equal to a preset threshold value and the required braking force is smaller than or equal to the maximum feedback braking force of the motor, the feedback braking force of the motor is adopted for braking so as to reduce the wheel speed; and when it is detected that the slip rate of the vehicle is smaller than or equal to a preset threshold value and the required braking force is larger than the maximum feedback braking force of the motor, the mechanical braking force and the feedback braking force of the motor are adopted for braking so as to reduce the wheel speed. According to the embodiment of the invention, the mechanical braking force and the feedback braking force are coordinated and optimized, so that the braking energy utilization rate is improved while the original ABS function is ensured.
