The invention relates to an electronic control unit (ECU) (10) for a vehicle, comprising a 12V domain (20) and a 48V domain (30), the 12V domain (20) being designed to control an electrical load (50) supplied with a first supply voltage (V12), and the 48V domain (30) being designed to control an electrical load (40) supplied with a second supply voltage (V48). The two domains (20, 30) are arranged on a single printed circuit board (RGB) and are galvanically isolated from each other and are connected to each other by a galvanically isolated data interface (11), said data interface (11) being designed to transmit data between the two domains (20, 30) according to a half-duplex or full-duplex communication protocol. The 48V domain (30) comprises a 48V microcontroller (32) and a 48V power supply (31) supplying the 48V microcontroller (32), the 48V power supply (31) being supplied by a first supply voltage (V12) from the 12V domain (20) via a galvanically isolated supply interface (12).
本发明涉及用于车辆的电子控制单元(ECU)(10),其包括12V域(20)和48V域(30),12V域(20)被设计为控制被供应有第一供给电压(V12)的电气负载(50),并且48V域(30)被设计为控制被供应有第二供给电压(V48)的电气负载(40)。这两个域(20、30)布置在单个印刷电路板(RGB)上并且彼此电流隔离,并且通过电流隔离的数据接口(11)彼此连接,所述数据接口(11)被设计为根据半双工或全双工通信协议在两个域(20、30)之间传输数据。48V域(30)包括48V微控制器(32)和供给48V微控制器(32)的48V电源(31),其中,48V电源(31)由来自12V域(20)的第一供给电压(V12)经由电流隔离的供给接口(12)来供电。
