摘要： A brake assistance system comprising a brake pedal, a booster motor, a simulation motor, a planetary row coupling node, and a brake master cylinder, where 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 coupled 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.
