Abstract: Novel systems and methodologies for precise indoor positioning employs a plurality of synchronized beacons emitting uniquely identifiable acoustic positioning signals in synchronized fashion to one another for receipt by microphone-equipped tracking devices, and beacon controllers emitting wireless synchronization signals receivable by RF receivers of those devices, at least one of which has multiple microphones to enable calculation of both position and orientation. An onboard IMU of each tracking device is used for dead reckoning between acoustic epochs, and for efficiently targeted searching of expected acoustic signals in the captured audio samples. Audio and IMU data captured by the target device is used for event detection purposes, and in the case of the former, to diagnose and remediate or mitigate environmental noise of detriment to the acoustic positioning functionality.

Abstract: One aspect of the invention relates to a method for signaling information to the operator of the remote control for a parking assistance system which can be controlled by remote control from outside of a motor vehicle for automatically parking the motor vehicle into a parking space. The method includes detecting surroundings information with respect to the vehicle surroundings on the motor vehicle side using a surrounding sensor system of the motor vehicle. The parking assistance system in the motor vehicle detects a parking space on the basis of the surroundings information, and information on the detection of a parking space is transmitted from the motor vehicle to the remote control via a wireless communication connection. On the basis of the received information, the remote control signals the presence of the detected parking space to the operator.
