Abstract: An integrated circuit for use in a first vehicle may include: an interface circuit that communicates with a second integrated circuit in a second vehicle; and a processing circuit. During operation, the processing circuit may determine that the second vehicle has better situational awareness for a portion of a road or an environment proximate to the road than the first vehicle, where the second vehicle is proximate to the first vehicle. Then, the processing circuit may dynamically establish, with the second integrated circuit, a communication pairing with the second vehicle. Moreover, the integrated circuit may exchange, via the pairing, information with the second integrated circuit. For example, the exchanged information may include or may specify: measurement data, one or more detected objects, one or more object identifiers, seed information for a detection technique (such as a priori information), and/or a priority or urgency of the exchanged information.

Abstract: An interface circuit may convert an input electrical signal at an input node in a first power domain having a first ground or reference voltage into an output electrical signal at an output node in a second power domain having a second ground or reference voltage. Notably, a level-shifting circuit in the interface circuit may selectively electrically couple to the input node and the output node. Then, when there is electrical coupling, the level-shifting circuit may perform level shifting between the first power domain and the second power domain. The level shifting may involve: passing, using a first filter, frequencies in the input electrical signal below a first corner frequency; passing, using a second filter in parallel with the first filter, frequencies in the input electrical signal above a second corner frequency; and combining outputs of the first filter and the second filter as the output electrical signal.
