    Abstract: A head up display system of a vehicle includes: a communication module configured to receive a period until a traffic signal of an intersection of roads will change from a first state to a second state; a distance module configured to, based on the period and a present speed of the vehicle, determine a distance in front of the vehicle where the vehicle will be when the traffic signal transitions from the first state to the second state; a light source configured to, via a windshield of the vehicle, generate a virtual display that is visible within a passenger cabin of the vehicle; and a display control module configured to, based on the distance, control the light source to include, in the virtual display, a visual indicator of a location in a path of the vehicle where the traffic signal will transition from the first state to the second state.

    Abstract: A system and method that pertain to a rotating vehicle display unit that can automatically or manually rotate between landscape and portrait orientations, depending on the particular display format or media being shown to the vehicle occupants. The rotating vehicle display unit uses an electro-mechanical rotating and locking mechanism with smart fluid, such as magnetorheological fluid (MR), to facilitate easy and precise rotational movement between different display orientations. The rotating vehicle display unit may be coupled to a corresponding human-machine interface (HMI) that responds to the different display orientations and helps facilitate easy transition from one orientation to another in order to optimize the particular display format or media being shown at that time.

    Abstract: A system for measuring passenger satisfaction of a passenger in a vehicle may include a first sensor structured to detect a first property of the passenger and a processor operably coupled to the first sensor. The processor structured to calculate a passenger satisfaction index based on the first property of the passenger. A method for measuring passenger satisfaction in a vehicle may include detecting, with a first sensor, a first property of the passenger; calculating, with a processor, a passenger satisfaction index based on the first property of the passenger.

    Abstract: A processor-implemented path planning method in a vehicle is disclosed. The method includes retrieving road surface information along a planned path for the vehicle; constructing, by the processor, a model of the road surface along the planned path; identifying, by the processor, a road irregularity in the road surface for the planned path; classifying, by the processor, the road irregularity; projecting the location of vehicle tire patches on the model of the road surface; predicting, by the processor, vehicle sprung-mass dynamics as a function of time for the vehicle along the planned path; calculating a plurality of alternative path trajectories within the constraints of the road boundaries for avoiding the road irregularity; choosing an alternative path trajectory out of the plurality of alternative path trajectories that reduces the sprung-mass dynamics for the vehicle to provide a more comfortable ride; and updating the planned path with the chosen alternative path trajectory.
