The invention provides a redundant self-locking power supply control circuit, an electronic mechanical braking system and an automobile, and relates to the technical field of braking control. A first power supply module is connected with a first power receiving module through a switching tube Q1 in sequence; the second power supply module is connected with the first power receiving module through a switching tube Q4; one input end of the comparator U1 is connected with reference voltage, the other input end of the comparator U1 is connected with the first power receiving module, and the output end of the comparator U1 is connected with the control end of the switching tube Q1 and the control end of the switching tube Q4. The problem that in the prior art, when a power supply in an electronic mechanical brake system goes wrong, time consumed for starting a standby power supply to supply power to a brake motor is long is solved.
本发明提供了一种冗余自锁供电控制电路、电子机械制动系统及汽车,涉及制动控制的技术领域,包括:第一供电模块依次通过开关管Q1与第一受电模块相连;第二供电模块通过开关管Q4与第一受电模块相连;比较器U1的其中一个输入端连接有基准电压,比较器U1的另一个输入端与第一受电模块相连,比较器U1的输出端分别与开关管Q1的控制端和开关管Q4的控制端相连。本发明解决了现有技术中存在的当电子机械制动系统中的供电源出现问题时,执行启用备用电源对制动电机进行供电耗时较长的问题。
