    Abstract: A cooling system for an autonomous vehicle receives a first flow rate data from a first flow rate sensor circuit and a second flow rate data from a second flow rate sensor circuit. The first flow rate data indicates a first flow rate of the liquid coolant flowing out of a first pump. The second flow rate data indicates a second flow rate of the liquid coolant flowing out of a second pump. The system detects that the first flow rate of the liquid coolant is less than a threshold flow rate. In response, the system communicates, to the second pump, a signal that indicates to increase a speed of the second pump to increase the second flow rate of the liquid coolant flowing out of the second pump and compensate for the first flow rate that is less than the threshold flow rate.

    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: Systems and methods for dynamic predictive control of autonomous vehicles are disclosed. In one aspect, an in-vehicle control system for a semi-truck includes one or more control mechanisms configured to control movement of the semi-truck and a processor. The system further includes computer-readable memory in communication with the processor and having stored thereon computer-executable instructions to cause the processor to receive a desired trajectory and a vehicle status of the semi-truck, determine a dynamic model of the semi-truck based on the desired trajectory and the vehicle status, determine at least one quadratic program (QP) problem based on the dynamic model, generate at least one control command for controlling the semi-truck by solving the at least one QP problem, and provide the at least one control command to the one or more control mechanisms.
