The invention relates to a power supply processing circuit, an automobile anti-lock braking system and an automobile, and the power supply processing circuit comprises a shunting module which is used for providing a first power supply input end meeting first preset power and a second power supply input end meeting second preset power; the voltage suppression module is used for clamping the voltage of the corresponding power supply input end to a preset voltage value when any power supply input end meets a preset suppression condition; the filtering module is used for filtering noise meeting a preset filtering condition in the first power supply input end and/or the second power supply input end; and the protection module is used for executing corresponding protection operation when the filtered first and/or second power supply input end meets a preset protection condition so as to protect the power supply processing circuit. Therefore, the problems that a power module of an automobile anti-lock braking system is unreasonable in shunting, noise cannot be removed, and effective protection is lacked for sudden reverse prevention and overcurrent are solved, the stability of the whole plate is improved, noise is effectively restrained, and stable degradation of functions is achieved.

    本申请涉及一种电源处理电路、汽车防抱死系统及汽车,包括:分流模块,用于提供满足第一预设功率的第一路供电输入端和满足第二预设功率的第二路供电输入端;电压抑制模块,用于在任一供电输入端满足预设抑制条件时,将对应的供电输入端电压箝位至预设电压值;滤波模块,用于滤除第一和/或第二路供电输入端中满足预设滤除条件的噪声;保护模块,用于在滤波后的第一和/或第二路供电输入端满足预设保护条件时,执行对应的保护操作,以保护电源处理电路。由此,解决汽车防抱死系统的电源模块分流不合理,无法去除噪声以及面对突发的防反、过流缺少有效保护等问题,提高整版的稳定性,有效抑制噪声,实现功能的平稳退化。
