Dynamic current sense adjustment for ring-like power distribution

An electronic control unit (ECU) for use in a ring-like power distribution architecture, comprising:

• an ECU terminal for providing power to a power drain (PD) terminal of a power drain;
• wherein the ECU performs operations comprising:
• receiving a signal from the power drain, wherein the signal is configured to indicate to the ECU to adjust a sensitivity of an ECU fuse associated with the ECU terminal;
• and
• adjusting the sensitivity of the ECU fuse associated with the ECU terminal based on the signal.

A ring-like power distribution architecture, comprising:

• a first electronic control unit (ECU) comprising:
• a first ECU terminal for receiving power from a first power source (PS) terminal of a first power source;
• wherein the first ECU performs operations comprising:
• determining whether current is flowing into the first ECU terminal or out of the first ECU terminal;
• and
• adjusting a sensitivity of a first ECU fuse associated with the first ECU terminal based on whether current is flowing into the first ECU terminal or out of the first ECU terminal;
• and
• a second ECU comprising:
• a second ECU terminal for providing power to a power drain, PD, terminal of a power drain;
• wherein the second ECU performs operations comprising:
• receiving a signal from the power drain, wherein the signal is configured to indicate to the second ECU to adjust a sensitivity of an ECU fuse associated with the second ECU terminal;
• and
• adjusting the sensitivity of the ECU fuse associated with the second ECU terminal based on the signal;
• and
• wherein the second ECU functions as the first power source and the first ECU functions as the power drain.
