Abstract: A system for detecting a health condition of an occupant of a vehicle includes a plurality of vehicle sensors and a controller in electrical communication with the plurality of vehicle sensors. The controller is programmed to perform a plurality of measurements using the plurality of vehicle sensors determine a health risk probability based at least in part on the plurality of measurements. The health risk probability is a probability that the occupant of the vehicle has the health condition. The controller is further programmed to notify the occupant of the vehicle in response to determining that the health risk probability is greater than or equal to a predetermined health risk threshold.

Abstract: A driver command interpreter system for a vehicle includes one or more controllers that execute instructions to receive a plurality of dynamic variables, vehicle configuration information, and driving environment conditions, and determine a target vehicle state during transient driving conditions based on the plurality of dynamic variables from the one or more sensors, the vehicle configuration information, and the driving environment conditions. The one or more controllers build a transient vehicle dynamic model based on the target vehicle state during transient driving conditions, the plurality of dynamic variables, the vehicle configuration information, and the driving environment conditions, and solve for desired zeros corresponding to the target vehicle state during transient conditions.

Abstract: A method for mitigating an adversarial attack includes receiving input data. The input data includes sensor data from a plurality of sensors and map data. The method further includes monitoring, in real time, an environment around an autonomous vehicle to identify a region that is possibly subject to an adversarial attack and determining a probability of the adversarial attack in the region. The method further includes determining whether the probability of the adversarial attack in the region that is possibly subject to the adversarial attack is greater than a predetermined threshold and, in response, planning a motion of the autonomous vehicle by taking into account the adversarial attack to generate a planned motion. The method further includes controlling a host vehicle to move in accordance with the planned motion.

Abstract: A vehicle trajectory planning system includes a perception system of a host vehicle collecting information from multiple sources and communicating with a computer. A fusion module fuses scene information from a map and perception items identified by the perception system. A behavior planning module receives an output of the fusion module and produces a host vehicle baseline trajectory. A trajectory and motion planning module receives an output of the fusion module in parallel with the behavior planning module. The trajectory and motion planning module determines a reference trajectory and operation corridor for a host vehicle. A disturbance and reachability refiner module receives an output of the trajectory and motion planning module including the reference trajectory and operation corridor. An algorithm is applied to adjust and re-plan the host vehicle baseline trajectory to be robust to a range of inclement weather conditions.

Abstract: Disclosed are a method for message match table lookup, a system, a non-transitory computer-readable storage medium and a terminal. The method for message match table lookup includes: performing on-demand data bit width compression on information of a specified part of an input message; extracting N groups of data from compressed data, performing intra-group data comparison to obtain N groups of comparison results, and performing true value splicing on the N groups of comparison results, where N is an integer greater than 1; performing match searching of a ternary content addressable memory (TCAM) by using the true value splicing result as a keyword; and searching, according to a match hit result of the TCAM, for an Action Random Access Memory (Action RAM), and outputting, by the Action RAM, a table lookup request.

Abstract: A system and method of manufacturing an aluminum fuel cell cradle includes providing a negative cast mold having cavities to form the cradle having a length greater than a width to define a longitudinal axis and providing a feeding mechanism disposed about the mold and in fluid communication with the cavities thereof. The feeding mechanism includes primary risers connected to and in fluid communication with the cavities. The method further includes melting a first metallic material to define a molten metallic material, moving the mold to a vertical orientation about the longitudinal axis while feeding molten metallic material through the runner to the cavities, and moving the cast mold to a horizontal orientation. A second solidification time in the risers is greater than a first solidification time in the mold such that shrinkage of the solidified metallic material occurs in the risers away from the mold.

Abstract: A system for controlling turbocharger shaft speed for an internal combustion engine (ICE) includes sensors and actuators and control modules in communication with the sensors and actuators. The control modules store and execute control logic that generates a predicted shaft speed from turbocharger shaft speed data. A shaft speed control algorithm (SSCA) is selectively initialized. The SSCA generates lower and upper limits to turbocharger flow corrections applied via the actuators. Closed loop control outputs are applied selectively to the actuators to control a mass flow through a compressor of the turbocharger. The SSCA selectively determines the shaft speed has exceeded a threshold, and the actuators alter a pressure ratio of the ICE. The SSCA operates the turbocharger stably within predefined hardware limits at an optimum shaft speed while maintaining constant flow across a range of pressure ratios. A long-term memory learning process trims turbocharger performance.
