    Abstract: Methods and systems are provided for controlling parking of an autonomous vehicle. A method of parking an autonomous vehicle includes receiving sensor data indicative of an exterior environment of the autonomous vehicle. The received sensor data is processed to determine a parking space characterization. Additional sensor data is received that is indicative of an occupant location within the autonomous vehicle. A processor determines a parking position within a parking space based on the parking space characterization and the occupant location. The processor generates control signals to operate one or more actuator devices to maneuver the autonomous vehicle into the parking space at the parking position.

    Abstract: In an exemplary embodiment, a system is provided that includes one or more first sensors, one or more second sensors, and a processor disposed onboard a vehicle. The first sensors are configured to at least facilitate obtaining first sensor data with regard to an external environment outside the vehicle. The second sensors are configured to at least facilitate obtaining second sensor data with regard to one or more eyes of a driver of the vehicle. The processor is configured to at least facilitate: determining a predicted gaze angle of the one or more eyes of the driver based on the external environment outside the vehicle, using the first sensor data; determining a measured gaze angle of the one or more eyes of the driver, using the second sensor data, and controlling one or more vehicle actions based on a comparison of the predicted and measured gaze angles.

    Abstract: Vision sensor detection systems and methods for mobile platforms that proactively prepare for impending lighting scenarios. The method includes determining or predicting a lighting scenario (LS) as a function of GPS data and wirelessly received mapping data. An on-board camera system is then operated in the LS using an associated predefined profile (PDP) having a tone-mapping setting associated with the LS. Received sensor data and camera data is used to confirm each predicted and current LS; Each predicted LS change results in retrieval of an associated PDP with its tone-mapping setting. Each confirmed LS results in using the sensor data and camera data to customize the tone-mapping setting. The method cycles during operation of the mobile platform.

    Abstract: An automotive vehicle includes a propulsion system, at least one wheel brake, a sensor configured to detect objects external to the vehicle, and a controller. The controller is configured to, in response to the sensor detecting a first target vehicle in the path of the host vehicle and a second target vehicle in the path of the host vehicle, automatically control the propulsion system and the at least one wheel brake based on a first relative velocity associated with the first target vehicle, a first relative acceleration associated with the first target vehicle, a second relative velocity associated with the second target vehicle, and a second relative acceleration associated with the second target vehicle.
