The invention discloses an automobile, a vehicle-mounted DC/DC conversion module, a power supply system and a driving method. The conversion module comprises a DC/DC converter and a microcontroller. The microcontroller meets the ASIL-D safety level, the input end of the microcontroller is connected with the input end IN, the state monitoring end PGOOD, the enabling end EN and the output end OUT end of the DC/DC converter, and the output end of the microcontroller is connected with the intelligent driving controller. The microcontroller judges the fault state of the DC/DC converter according to the input voltage, the internal operation state, the enabling state and the output voltage of the DC/DC converter, so that the intelligent driving controller controls the driving mode of the vehicle according to the fault state. According to the invention, the problems of difficulty in model selection, inconvenience in purchasing and small loading capacity of the power supply chip meeting function safety are solved.

    本申请公开一种汽车及车载DC/DC转换模块、供电系统、驾驶方法,所述转换模块包括DC/DC转换器和微控制器;微控制器满足ASIL‑D安全等级且其输入端分别与DC/DC转换器的输入端IN、状态监测端PGOOD、使能端EN和输出端OUT端连接,微控制器的输出端与智能驾驶控制器连接;微控制器根据DC/DC转换器的输入电压、内部运行状态、使能状态以及输出电压判断DC/DC转换器的故障状态,使智能驾驶控制器根据故障状态控制车辆的驾驶模式。本发明解决了满足功能安全的电源芯片选型困难,采购不便以及带载能力小的问题。
