Oh what a tangled mess we weave


I scribbled a post on the evils of persisting central electrics earlier today. While composing that article, I updated the information of the tailgate node to illustrate how it could reduce the peak current load, allowing the use of smaller and more flexible wires.

Similar measures can be implemented in e.g. the doors by stopping the mirrors from moving and being heated while the lock actuator is working.

As the voltage drop through a wire is related to the total current draw, reducing the load temporarily lets something else happen for a fraction of a second to three, providing a higher operating voltage for that action.

After adding a diagram, I promoted today’s earlier post to a page so that it doesn’t slip away with the blog post history.

The LIN Node Design page now has a diagram showing the locations of nodes and their clusters.
