Abstract: Systems and methods for complementary control of an autonomous vehicle are disclosed. A primary controller provides a first plurality of instructions to an AV platform for operating the AV in an autonomous mode along a planned path based on sensor data from a primary sensor system and a secondary sensor system, and provides information that includes a fallback monitoring region to a complementary controller. The complementary controller receives sensor data from the secondary sensor system that includes sensed data for a fallback monitoring region, analyzes the received sensor data to determine whether a collision is imminent with an object detected in the fallback monitoring region, and cause the AV platform to initiate a collision mitigation action if a collision is determined to be imminent.

Abstract: A vehicle includes a low-voltage battery, a high-voltage battery, and a converter that decreases voltage provided from the high-voltage battery to the low-voltage battery. A system controller of the vehicle is programmed to use the converter, in a key-off cycle, to charge the low-voltage battery a calibrated number of times that the low-voltage battery drops below a predefined state-of-charge threshold, and send a wireless notification a subsequent time the low-voltage battery drops below the threshold. A notification is sent to a predefined contact address when a periodically computed state of charge of a low-voltage battery of a vehicle falls below a predefined threshold. Using a converter, voltage provided from a high-voltage battery of the vehicle to the low-voltage battery is decreased to charge the low-voltage battery responsive to receipt from the contact address of a response indicating approval of the charge.
