In order to meet the new requirements, a novel electric power-assisted braking system is created, an additional vacuum pump is not needed, and meanwhile, the power-assisted size is controllable, namely, the power-assisted motor can be used for assisting less power or not assisting power as required, so that the control is more convenient. A fixed braking curve is preset in the novel electric power-assisted braking system, and the braking curve is a relation curve of the travel of a brake pedal and the deceleration of a vehicle.

None of the current braking systems, however, meets the above-mentioned needs.

Preferably, the step of receiving a braking mode selection command input by a user specifically includes: and receiving a braking mode selection command input by a user through a man-machine interface device of the vehicle.
The braking mode selection commands can carry different braking mode information, but each braking mode selection command only carries one type of braking mode information, so that the braking mode which a user wants to select to use can be determined according to the braking mode selection command.
