  • Patent number: 11866066
    Abstract: Systems and methods to perform behavioral planning in an autonomous vehicle from a reference state involve generating a set of actions of a fixed size and fixed order according to a predefined methodology. Each action is a semantic instruction for a next motion of the vehicle. A set of trajectories is generated from the set of actions as an instruction indicating a path and a velocity profile to generate steering angles and accelerations for implementation by the vehicle. A trajectory filter is applied to filter the set of trajectories such that unfiltered trajectories are candidate trajectories. Applying the trajectory filter includes assessing the path and velocity profile indicated by each of the set of trajectories. A selected trajectory is used to control the vehicle or the action that corresponds to the selected trajectory is used in trajectory planning to generate a final trajectory that is used to control the vehicle.

    Abstract: A battery cell pack has a plurality of battery cells that are assembled into a prismatic frame, with deformable separators interposed to accommodate elastic and plastic deformation caused by cyclic and acyclic expansion and contraction thereof during charging and discharging over the life of the battery cell pack. The battery cells are arranged in a horizontal stack within the prismatic frame, and the deformable separators are interposed between subsets of the battery cells. The deformable separators exert compressive force on the subsets of the battery cells along a longitudinal axis that is defined by the horizontal stack. The compressive force exerted by the deformable separators is at least a minimum force over a service life of the battery cell pack.

  • Publication number: 20240001963
    Abstract: Vehicles and related systems and methods are provided for controlling a vehicle in an autonomous operating mode. One method involves identifying a stationary object outside a current lane of travel based at least in part on sensor data captured onboard the vehicle, determining an estimated location for the stationary object based at least in part on the sensor data and a location of the vehicle and providing the estimated location to a remote system. The remote system updates lane preference information corresponding to the estimated location for the stationary object when the stationary object satisfies one or more avoidance criteria. The method continues by determining a trajectory for a vehicle to change lanes based at least in part on the updated lane preference information and autonomously operating one or more actuators onboard the vehicle in accordance with the trajectory.
