The invention relates to the technical field of automobile braking, and discloses a brake-by-wire device with a redundancy function and a control method.The brake-by-wire device comprises a rotating device, a transmission device and a control device.The rotating device comprises a brake disc, and a circular axle through hole is formed in the surface of one side of the brake disc; the transmission device comprises calipers, a connecting disc, a brake pad and a connecting spring, the control device comprises an electricity storage box, motors, a connecting plate and an electric telescopic rod, the two motors are arranged in the electricity storage box, and a signal switching unit is arranged in the electricity storage box. According to the brake-by-wire device with the redundancy function and the control method, the redundancy function is achieved through the use of the double motors, rotation of the brake disc drives rotation of an operation assembly in the first piston at the lower end, it is guaranteed that the rotation speed is consistent, the response speed of a brake can be shortened in the high-speed running process, and the service life of the brake is prolonged. Compared with a traditional brake-by-wire device, the brake-by-wire device has the advantages of being high in influence speed and low in cost, and safety and reliability of a brake system are improved.

    本发明涉及汽车制动技术领域,且公开了一种具有冗余功能的线控制动装置及控制方法,本发明包括转动装置、传动装置以及控制装置,转动装置包括制动盘,制动盘一侧表面设有圆形的车轴通孔,传动装置包括卡钳、连接盘、刹车片以及连接弹簧,控制装置包括蓄电箱、电机、连接板以及电动伸缩杆,蓄电箱内部设有两个电机,蓄电箱内部设有信号切换单元。本发明一种具有冗余功能的线控制动装置及控制方法,利用双电机的使用实现冗余功能,制动盘的转动带动下端第一活塞内部运行组件的转动,保证转动速率速率的一致,在高速行驶的过程中能够缩短制动器的反应速度,相比于传统线控制动装置,具有影响速度快,成本低的特点,提高了制动系统的安全可靠性。
