Abstract
Systems and methods are provided for controlling power modes of a vehicle and for providing passive entry to the vehicle. A sleep command can be sent from a central controller to multiple domain controllers to enter a sleep state. When the sleep command is received by a first domain controller, a sleep state is entered. When the sleep command is received by a second domain controller, a stealth state is entered. While in the stealth state, the second domain controller periodically wakes up from a sleep state to monitor a condition. In response to detecting a first condition, the second domain controller returns to the sleep state. In response to detecting a second condition, the second domain controller sends a notification of the second condition to the central controller.
