Abstract:
A starter relay connects a battery with a starter motor of an engine when in a closed state and disconnects the starter motor from the battery when in an open state. A switching device provides current to the starter relay when in a closed state and disables current flow to the starter relay when in an open state. For an engine startup event, a switch control module: transitions the switching device to the closed state for a first predetermined period; transitions the switching device to the open state for a second predetermined period after the first predetermined period; and transitions the switching device to the closed state for a third period after the second predetermined period. The starter relay remains in the open state during the first predetermined period and transitions to the closed state when the switching device is in the closed state for the third period.
