Abstract: A vehicle computer includes a processor programmed to confirm an identity of a limited user prior to permitting the limited user to enter an autonomous host vehicle, monitor autonomous operation of the host vehicle, and transmit a status update to a primary mobile device associated with a supervisor user of the host vehicle during autonomous operation of the autonomous host vehicle.

Abstract: Method and apparatus are disclosed for remote starting of engines via vehicle keypads. An example vehicle includes a keypad, a communication module to communicate with a mobile device designated as a wireless key, and a vehicle activator. The vehicle activator is to remote start an engine in response to receiving a first code entered via the keypad when a battery of the mobile device is discharged and authorize control of the engine in response to the communication module establishing communication with the mobile device.

Abstract: Method and apparatus are disclosed for secure idle for a vehicle generator. An example vehicle includes an outlet external to the vehicle, a power inverter dedicated to supplying AC power to the outlet, and a powertrain control module. The powertrain control module controls the power inverter to supply first power level when a switch is in a first position and a second power level when the switch is in a second position. Additionally, the powertrain control module, after entering a secure mode, controls an engine to remain idling when an ignition switch is off.

Abstract: Systems and methods for managing keys that operate a given vehicle include a processor. Responsive to identifying a received first key for operating the vehicle as having an administrative status, the processor is configured to enable creation of a second key for operating the vehicle having the administrative status, and enable creation of a third key for operating the vehicle having a secondary status and a passcode. Responsive to receiving and identifying the third key as having the secondary status, the processor is configured to enable alteration of the passcode.

Abstract: Embodiments include a vehicle comprising a plurality of antennas positioned at locations inside and outside a vehicle cabin, each antenna being in wireless communication with an external mobile device and being associated with signal strength information; and a central module in communication with the antennas and configured to identify the antennas with the two strongest signals, and determine a mobile device location relative to the vehicle cabin based on the locations of the identified antennas. Embodiments also include a method comprising receiving signal strength information associated with a plurality of antennas wirelessly communicating with a mobile device, the antennas positioned at locations inside and outside a vehicle cabin; identifying a first antenna having a first highest signal strength and a second antenna having a second highest signal strength; and determining a mobile device location relative to the vehicle cabin based on the locations of the first and second antennas.

Abstract: Methods and systems for selecting vehicle operating modes in response to output of remote security token devices are described. In one example, a vehicle operating mode may be determined when two key fobs having different, but valid, security token assignments are present within a vehicle cabin. Further, one mode of a two mode key fob may be selectively deactivated and reactivated to provide system flexibility.

Abstract: An access system for a vehicle may include a controller. The controller may be configured to respond to receiving an unlock signal indicative of an unlock request by causing a compartment closure to unlock for a predetermined time. Or the controller may be configured to respond to receiving an unlock signal indicative of an unlock request and a vehicle operation signal indicative of a vehicle secure state by causing a compartment closure to unlock for a predetermined time. Upon expiration of the predetermined time, the controller may cause the compartment closure to lock. The controller may be configured to respond to receiving an unlatch signal indicative of an unlatch request during the predetermined time by causing the compartment closure to unlatch.

Abstract: An unattended-vehicle engine-idling system controls a vehicle powertrain in a non-motive mode with the engine running. An ignition switch operables with a removable ignition key. A control circuit has multiple states including a PREARMED state which is entered when the powertrain is in the motive mode and the user generates a manual activation signal. An ARMED state is entered when the transmission is in Park and holds an ignition switch status signal at RUN. An ACTIVE state is entered when the ignition switch is moved to the Accessory or Off positions or the key is removed. The powertrain is switched to non-motive mode and the switch status signal stays at RUN. A DISARMED state is entered in response to a manual deactivation signal generated independently of the ignition switch. In the DISARMED state, the ignition switch status signal corresponds with the ignition switch position, thereby turning off the engine.
