This application provides an electro-mechanical brake apparatus with an offset transmission shaft of a reducer, a system, and a vehicle. The electro-mechanical brake apparatus is configured to be fastened to a brake caliper and drive a friction plate to brake a wheel. The electro-mechanical brake apparatus includes a brake motor and the reducer. The brake motor includes a rotor and a stator. The reducer includes the transmission shaft and a planetary gear set. An axis of the transmission shaft is offset to an axis of the rotor along a radial direction of the brake motor, the rotor is configured to drive the transmission shaft to rotate around the axis of the rotor, the transmission shaft is configured to drive, through a planet gear of the planetary gear set, a sun gear of the planetary gear set to rotate, and the sun gear is configured to drive the friction plate through a feed mechanism. In this application, the electro-mechanical brake apparatus uses the rotor to form a structure similar to a planet carrier in the planetary gear set of the reducer, to implement integral integration of the brake motor and the reducer. This reduces an axial size of the electro-mechanical brake apparatus, and implements miniaturization of the electro-mechanical brake apparatus on a premise of ensuring reliable braking of the electro-mechanical brake apparatus.
