The invention provides a high-redundancy vehicle braking system, wherein motion state information of a braking pedal in treading is sensed through a pedal movement sensor. A control unit controls the operation modes of a first linear electromagnetic driver and a second linear electromagnetic driver based on motion state information of the braking pedal and an in-cylinder pressure state of a braking main cylinder so that the operation modes of the first linear electromagnetic driver and the second linear electromagnetic driver are at least one selected from a feedback driving mode and a boost driving mode. In the feedback driving mode, the second linear electromagnetic driver is driven for generating a resistance which hinders advancing of the braking pedal. In the boost driving mode, the second linear electromagnetic driver is driven for generating a pushing force which pushes the piston of the braking main cylinder to move. By means of the high-redundancy vehicle braking system, the linear electromagnetic driver as a braking sensing feedback mechanism can be performed for performing boost processing on condition that another linear electromagnetic driver is abnormal or fails, thereby improving reliability of the whole braking system.
