  • Publication number: 20240140449
    Abstract: A system for planning motion of a vehicle includes a controller having a processor and tangible, non-transitory memory on which instructions are recorded. The vehicle is capable of an automated driving operation. A planning module is executable by the controller to generate a vehicle trajectory constrained by a set of planning parameters. During a degraded driving situation, an adjustment module is executable by the controller to generate at least one adjusted parameter in the set of planning parameters. The controller is adapted to register occurrence of the degraded driving situation when the planning module is unable to generate a feasible path for the vehicle constrained by the set of planning parameters. The planning module is adapted to generate a modified trajectory plan based on the at least one adjusted parameter, with the automated driving operation being based on the modified trajectory plan during the degraded driving situation.

A liquid-gas separator assembly for an FCS includes an outer housing with an internal compartment, a first port fluidly connecting this internal compartment to an FCS transfer conduit to receive FCS exhaust, and a second port fluidly connecting the internal compartment to an FCS exhaust manifold to transfer water separated from the exhaust. A third port fluidly connects the internal compartment to an FCS hydrogen inlet to transfer hydrogen extracted from the exhaust. A first chamber located inside the internal compartment fluidly connects the first and second ports and evacuates extracted water from the compartment. A second chamber located inside the internal compartment above the first chamber fluidly connects the first chamber to the third port and evacuates extracted hydrogen from the compartment.
