At the same time, the wiring harness will also show fatigue characteristics due to frequent twisting, which may cause unstable operation of the vehicle.

[0003] For steering wheels with carbon brush structures, signal cross-talk and contact noise from the carbon brushes will reduce communication quality and introduce operational risks. Utility Model Content
