The invention belongs to the field of automobile design, and particularly relates to a power supply redundant circuit of an automobile body electronic stabilization system. The invention provides a power supply redundant circuit design for a vehicle provided with a vehicle body electronic stability program (ESP) device. The power supply redundant circuit design is provided for the vehicle provided with the ESP device. Through the circuit, the function safety is improved, and the risk that the main function and the additional function of the ESP are unavailable due to the failure of an external power supply (a wire harness or a fuse) is reduced. The two fuses are connected through the redundant power supply circuit, the two fuses independently supply power under normal conditions, when one fuse fails, the redundant power supply circuit automatically switches to the other fuse to supply power, the two fuses are redundant to each other, and as long as one fuse works normally, the ESP can achieve full functions.
本发明属于汽车设计领域,具体涉及一种车身电子稳定系统的电源冗余电路。本发明针对配有车身电子稳定系统(ESP,Electronic Stability Program)装置的车辆提供一种电源冗余电路设计。通过该电路,提升功能安全,降低由于外部供电(线束或者保险)失效,ESP主功能及附加功能不可用的风险。本发明将两路保险通过冗余电源路连接起来,正常情况两路保险丝独立供电,当其中一路保险丝失效,则通过冗余电源电路自动切换到另外一路保险供电,可实现两个保险互为冗余,只要有一个保险正常工作,则ESP可实现全功能。
