The invention relates to a power distribution design of an integrated braking system of a new energy automobile, in particular to a redundant power distribution design of a braking redundancy scheme of a vehicle carrying a full-automatic parking or automatic driving function. An IPB power supply and an RBU power supply are respectively placed in a PFB (pre-fuse box) and an EJB (forecabin fuse box), and the PFB is connected with a positive electrode of a storage battery through a copper bar and then distributes the power supply to electric appliances through a fuse; the power supply of the EJB is taken from the PFB through a fuse, and then the power supply is distributed to electric appliances through the fuse in the EJB. According to the invention, the problem of short circuit of the power supply of the braking system or braking failure during short circuit under extreme conditions can be effectively solved, the safety and stability of the whole vehicle are improved, and the automatic driving technology is effectively improved.

    本发明涉及新能源汽车集成式制动系统的配电设计,特别是一种搭载全自动泊车或自动驾驶功能车辆的制动冗余方案的冗余配电设计。本发明将IPB电源及RBU电源分别放置在PFB(预保险盒)和EJB(前舱保险盒)中,所述PFB通过铜排与蓄电池正极相连再经保险丝将电源分配给用电器;EJB的电源从PFB中经由保险丝取,EJB中再经过保险丝将电源分配给用电器。本发明可有效地解决了极端情况下制动系统电源短路或短路时制动失效的问题,提高了整车的安全性、稳定性,有效的为自动驾驶技术添砖加瓦。
