A control unit (CU) for an electric vehicle includes a control pilot (CP) transmitting unit (CPS), a CP receiving unit (CPR), and a semiconductor switching device. A CP transmitting unit (CPS) is configured to generate and transmit a CP signal, and a CP receiving unit (CPR) is configured to receive the CP signal. An input (CPin) of a CP receiving unit (CPR) for receiving CP signals and an output (CPout) of a CP transmitting unit (CPS) for transmitting CP signals are directly connected to a single connector pin (PINc) of the control unit. The CP transmitting unit (CPS) includes a buffer (OA) configured to output a pulse width modulated signal, and the semiconductor switching device is configured to connect the buffer (OA) to the at least one supply voltage during a CP transmitting mode and disconnect the buffer (OA) from the at least one supply voltage during a CP receiving mode.

    一种用于电动车辆的控制单元(CU)包括控制导频(CP)发送单元(CP_S)、CP接收单元(CP_R)和半导体切换器件。CP发送单元(CP_S)被配置成生成并发送CP信号,并且CP接收单元(CP_R)被配置成接收CP信号。用于接收CP信号的CP接收单元(CP_R)的输入(CP_in)和用于发送CP信号的CP发送单元(CP_S)的输出(CP_out)直接连接到所述控制单元的单个连接器引脚(PIN_c)。CP发送单元(CP_S)包括缓冲器(OA),缓冲器(OA)被配置成输出脉冲宽度调制信号,并且半导体切换器件被配置成在CP发送模式期间将缓冲器(OA)与至少一个供给电压连接并且在CP接收模式期间将缓冲器(OA)从至少一个供给电压断开。
