Abstract: Devices, systems, and methods for constant and reliable power distribution, using a redundant power bridge battery architecture, in autonomous vehicles are described. An example method includes determining that each of a plurality of sensors is operating within in a nominal range for the respective sensor, and distributing, based on the determining, power from at least one alternating current (AC) power source or at least one direct current (DC) power source to at least one power distribution unit (PDU), wherein a first power bridge is coupled to the at least one AC power source and the at least one DC power source and a second power bridge is coupled to the at least one DC power source and the at least one PDU, and wherein the plurality of sensors is used to monitor a health of the vehicle and any single point failure is detectable.

Abstract: Devices, systems, and methods for hardware-based time synchronization for heterogenous sensors are described. An example method includes generating a plurality of input trigger pulses having a nominal pulse-per-second (PPS) rate, generating, based on timing information derived from the plurality of input trigger pulses, a plurality of output trigger pulses, and transmitting the plurality of output trigger pulses to a sensor of a plurality of sensors, wherein a frequency of the plurality of output trigger pulses corresponds to a target operating frequency of the sensor, wherein, in a case that a navigation system coupled to the synchronization unit is functioning correctly, the plurality of input trigger pulses is generated based on a nominal PPS signal from the navigation unit, and wherein, in a case that the navigation system is not functioning correctly, the plurality of input trigger pulses is generated based on a simulated clock source of the synchronization unit.

Abstract: A redundant hardware and software architecture can be designed to enable vehicles to be operated in an autonomous mode while improving the reliability and/or safety of such vehicles. A system for redundant architecture can include a set of at least two redundant sensors coupled to a vehicle and configured to provide timestamped sensor data to each of a plurality of computing unit (CU) computers. The CU computers can process the sensor data simultaneously based on at least a time value indicative of an absolute time or a relative time and based on the timestamped sensor data. The CU computers provide to a vehicle control unit (VCU) computer at least two sets of outputs configured to instruct a plurality of devices in a vehicle and cause the vehicle to be driven.
