This application provides a brake assistance system, a brake method, and an electric vehicle. The brake assistance system includes a brake pedal, a booster motor, a simulation motor, a planetary row coupling node, and a brake master cylinder. The brake master cylinder is configured to provide a braking force for the vehicle. The brake pedal, the booster motor, and the simulation motor are separately connected to the planetary row coupling node. The planetary row coupling node is configured to convert a torque of the brake pedal, a torque output by the booster motor, and a torque output by the simulation motor into an acting force acting on a piston rod in the brake master cylinder. It can be learned from the foregoing description that, the planetary row coupling node is disposed, so that both the torque output by the simulation motor and the torque output by the booster motor are used as the force for driving the piston rod of the brake master cylinder. This can reduce an output power requirement on a single motor. In addition, when two motors are used to drive the brake master cylinder at the same time, if one motor fails, the other motor can be used for braking, so that reliability of the entire brake assistance system is improved.
