The invention particularly relates to a control system of a vehicle-mounted DCDC converter. The control system comprises a main controller, a current acquisition module, a voltage acquisition module, a communication module, a PWN driving module, a fault protection module, a temperature acquisition module and a load control module. The main controller is used for receiving information from the peripheral circuit and issuing a command to the related peripheral circuit. The current acquisition module is used for sampling the current of the DCDC converter side for the sampling resistor, converting a current signal into a current range which can be accepted by the main controller, and transmitting the current range to the main controller; the main controller issues a command of starting acquisition or stopping acquisition to the current acquisition module so as to control whether the current acquisition module works or not; and the voltage acquisition module is used for sampling the current of the DCDC converter side for the sampling resistor, converting a current voltage signal into a level range which can be accepted by the main controller and transmitting the level range to the main controller.

    本发明具体涉及一种车载DCDC变换器的控制系统,包括主控制器、电流采集模块、电压采集模块、通讯模块、PWN驱动模块、故障保护模块、温度采集模块、负载控制模块。主控制器用于接收来自外设电路的信息,发布命令至相关的外设电路。电流采集模块用于对采样电阻进行采样DCDC变换器侧的电流,并将电流信号转换为主控制器能够接受的电流范围传输至主控制器;主控制器发布开始采集或者停止采集的命令至电流采集模块实现对电流采集模块是否工作的控制。电压采集模块用于对采样电阻进行采样DCDC变换器侧的电流,并将电流压信号转换为主控制器能够接受的电平范围传输至主控制器。
