Definitions

  • the first sub-ECU 11 includes a power supply IC 11a, a microcomputer 11b, and a communication IC 11c. It communicates and transmits the external world information acquired by the sensor to the microcomputer 1b. Note that the sensor main body is omitted. Communication between the main ECU 1 and the first sub ECU 11 is configured, for example, as a CAN bus.
  • the first switch control line 12g draws in the communication line from the CAN_H signal line or CAN_L signal line of the CAN bus, connects it to the first switch circuit 12e, and controls it according to the voltage fluctuation of the communication line.
  • the main board 100 includes a power supply IC 100a and a first microcomputer 100b, and communicates with the sub-board 101 through a UART communication line 100c and with the sub-board 102 through an SPI communication line 100e. It is connected to the sub-board by connectors 100g and 100h.
  • the voltage of the TX signal line 100d rises to High level.
  • the voltage of the first switch control line 101f of the sub-board 101 rises as the voltage of the communication line rises, and when it exceeds a certain threshold voltage, the first switch circuit 101d operates and causes the power control circuit 101c to supply power.
  • the power supply IC 101a operates and the second microcomputer 101b starts.
  • the first microcomputer 100b of the main board 100 can confirm that the power supply to the sub-board 101 has been cut off.
  • the present invention is not limited to the above embodiments, and includes various modifications.
  • the present invention is not limited to vehicles or automobiles, and can be applied to any electronic module connected via a communication line.
  • the above-described embodiments have been described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the described configurations.
  • it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment and it is also possible to add the configuration of another embodiment to the configuration of one embodiment.
