摘要： The present application relates to a braking method and a braking system. The braking method of the present application may be performed by an electro-mechanical braking system including at least one axle control unit and a plurality of electro-mechanical braking devices provided at ends of wheels and driven by motors to apply friction braking forces to the wheels. The electro-mechanical braking devices are controlled by at least one axle control unit to switch between a state in which no friction braking is applied and a state in which friction braking is applied in response to a braking requirement. The braking method includes: setting a brake clearance between a brake pad and a brake disc to an initial value; determining whether there is a braking requirement; determining whether regenerative braking is performed; and in response to the performing of regenerative braking, setting the brake clearance to a preset value, wherein the preset value is smaller than the initial value. The brake clearance is reduced before friction braking is required, the respond time to the friction braking requirement is shortened, so that the switch between friction braking and regenerative braking is smoother, thereby the pause and transition during the switch between brakings is effectively reduced.
