  • Publication number: 20230347887
    Abstract: Systems and methods are provided for lane biasing, e.g., positioning a vehicle within a current lane of travel. Lane biasing can be dependent on learned driver behaviors or other factors that may impact lane biasing, e.g., weather conditions, traffic conditions, and so on (which may also be learned). Lane biasing may result in a vehicle traveling, e.g., off the center-line of a current lane of travel, and is distinguished from conventional lane keep assist systems that merely position a vehicle in the center of a current lane of travel by default.

  • Patent number: 11801844
    Abstract: Systems and methods for controlling a vehicle using operational constraints, including friction estimates are disclosed. Friction estimation include estimating a tire-road coefficient of friction using bins and envelopes. Bounding envelopes are configured to ensure that stability of the vehicle is maintained. The friction estimate is used to define the bounding envelopes. Further, the bounding envelopes are received as feedback into the friction estimation, itself. Based on the bounding envelope, the friction estimation can be adjusted. Then, the adjusted friction estimation can be fed back to reshape the bounding envelopes. Multiple bins can be used to evaluate an operating range of friction. Each bin can be used to compare actual vehicle dynamics with expected dynamics based on the estimation using the range assigned to that bin. Multiple bins and multiple controllers can run in parallel to re-estimate friction considering the vehicle dynamics over time.

  • Publication number: 20230339431
    Abstract: A system is provided for implementing trajectory analysis entry controls. A trajectory analysis entry control system is implemented in a vehicle, and supports remote and automatic entry control functions for the vehicle. For example the system triggers various automatic entry controls functions, such as remotely unlocking doors and/or a trunk of a vehicle, by tracking and analyzing a user's trajectory of movement while they are approaching the vehicle. A system includes a user identification device to identify whether a user is authorized to access the vehicle, such as a driver. The system also includes a trajectory tracking device that determines a trajectory of the user with respect to the vehicle. As the user's trajectory is determined to be approaching the vehicle, the trajectory tracking device further determines which entry point of the vehicle the user is approaching and automatically engages an automatic unlocking of that access point of the vehicle.

  • Publication number: 20230339503
    Abstract: A system for producing a trajectory from a diverse set of possible movements can include a processor and a memory. The memory can store a possible movement production module and a trajectory production module. The possible movement production module can include instructions that cause the processor to: (1) produce a set of possible movements of a mobile robot with respect to a challenge, (2) determine a measure of diversity between a first possible movement and a second possible movement, and (3) produce a subset. Measures of diversity associated with possible movements included in the subset can be larger than measures of diversity associated with possible movements excluded from the subset. The trajectory production module can include instructions that cause the processor to: (1) produce trajectories associated with the possible movements included in the subset and (2) cause the mobile robot to move according to one of the trajectories.

  • Publication number: 20230339441
    Abstract: Systems and methods are provided for variable actuation and release of a vehicle's brake hold mechanism/function. A brake hold device may be implemented as a “tuner” or controller that can connect to and override, e.g., the default functionality of an existing brake hold mechanism of a vehicle. Delays in exiting a brake hold state, repetitive actuation of an accelerator to exit a brake hold state, and other shortcomings associated with the conventional operation of brake hold mechanisms may be avoided by taking into account relevant vehicle operating conditions or environmental/road/traffic conditions.

  • Publication number: 20230339382
    Abstract: Systems and methods for optimizing the loading or unloading of cargo in a cargo area is provided. Friction-reducing elements, such as rails, may be disposed atop a surface of the cargo area. The friction-reducing elements vibrate pursuant to the application of vibrational energy generated by one or more vibration actuators operatively connected, directly or indirectly, to the friction-reducing elements. The application of vibrational energy reduces the time that cargo contacts the friction-reducing elements, which in turn, reduces the amount of friction applied to the cargo, easing the burden of loading/unloading the cargo.

  • Publication number: 20230339288
    Abstract: A method for controlling a comfort component of a vehicle includes setting a comfort component, while a passenger is occupying the vehicle, to an active state to adjust a temperature within the vehicle to a passenger desired temperature based on receiving an input from the passenger. The method further includes maintaining, after the passenger exited the vehicle, the comfort component in an active state based on a likelihood of the passenger returning to the vehicle satisfying an active state condition. The method still further includes capturing, after the passenger exited the vehicle, an image of a person approaching the vehicle via one or more sensors of the vehicle. The method also includes adjusting the comfort component from the active state to a default state based on an identity of the person being different from an identity of the passenger, the identity of the person being determined based on the image.

  • Publication number: 20230343240
    Abstract: Systems and methods are provided for training and suggestion frameworks to improve driver operation of a vehicle. A driver may perform certain maneuvers frequently. Pairing these maneuvers with assigned stimuli may form an association in the driver's mind between the maneuver and the stimuli. A driving scenario may arise in which it would be safer, compliant, more efficient, or more effective for a driver to perform a certain maneuver. If a driver has formed a strong mental association between a maneuver and assigned stimuli, the assigned stimuli may be presented to prompt the driver to perform the maneuver. A driver may still retain ultimate control of a vehicle and may choose not to perform the maneuver.
