Abstract
A signal integration hub for automotive sensors measures battery voltage and provides an indication of that voltage to a processing microcontroller. A program executed on the microcontroller distinguishes between convenience and required function sensors and input circuits. When battery voltage is low, the microprocessor substitutes only for the convenience sensors their last debounced value during a time when battery voltage was not low. Inputs from required function sensors are not altered.
