The invention discloses a novel motor braking system and a braking force distribution method, and belongs to the technical field of automobile control, the novel motor braking system is formed by connecting a high-voltage power battery pack and a parallel bleeder resistor in parallel and connecting the high-voltage power battery pack with a series controllable dissipative load, a cooperative braking controller and a hub motor in series through a high-frequency change-over switch, and the hub motor is fixedly connected to a hub of a wheel. The novel motor braking system can broaden the braking limit boundary of the high-speed section of the motor and realize full-time and full-rotating-speed section motor constant torque control, so that the motor braking can independently undertake a part of braking tasks; according to the braking force distribution method based on the novel motor braking system, the maximum braking energy recovery effect and the maximum braking energy utilization effect can be guaranteed.
