Current limit management for multi-function systems

摘要

Exemplary methods are disclosed, which may include providing a conductive component configured to conduct a current to at least two electrical systems or elements. Methods may further include determining one of the electrical elements as a low-priority system and a second one of the electrical elements as a high-priority system, measuring or estimating a current associated with the at least two electrical systems to establish the current exceeds a predetermined parameter, and deactivating the low-priority system in response to at least the determination of the current exceeding the predetermined parameter.

1. A method, comprising:
providing a clockspring circuit having a predetermined current limit and including a fixed portion defining a steering wheel column and a rotating portion defining a steering wheel configured to rotate relative to the steering wheel column, the clockspring circuit configured to conduct current to a plurality of electrical elements including a steering wheel heating device and an active steering system; determining a low-priority system and a high-priority system included in the electrical elements; measuring current through the clockspring circuit to establish the predetermined current limit is exceeded; and deactivating the low-priority system in response to at least the determination of the predetermined current limit being exceeded.
