Description

Vehicle seat management system Background Vehicle occupants and drivers often feel tired and uncomfortable during road travel. This is especially true for individuals sitting in vehicle seats most of the day and/or for individuals traveling long distances. As should be appreciated, driver fatigue is a condition that may lead to impaired motor skills and increased likelihood of vehicle collisions. Similarly, both passengers and drivers are at risk of developing long-term health problems due to sitting in uncomfortable sitting positions for a longer period of time. Currently, vehicle anti-fatigue seating systems are often factory preset. In some cases, these preset factory movement algorithms fail to provide comfort and fatigue resistance to all users in various applications. For example, the same seat movement algorithm may not be as effective for large-size adults as for small-size teenagers. Similarly, vehicle data such as location, road conditions, and/or speed may not be taken into account. In many applications, it would be advantageous to have a seat adjustment algorithm that is personalized and calculated based on various occupant and/or vehicle data. Accordingly, improvements are needed in this area. Disclosure of Invention A vehicle seat management system for providing anti-fatigue capability to passengers is disclosed. In one aspect, the vehicle seat management system includes one or more seat adjustment inputs. In one example, the one or more seat adjustment inputs may be a seat adjustment algorithm. In another aspect, the one or more seat adjustment inputs are created from a combination of occupant and/or vehicle data. In yet another aspect, the one or more seat adjustment inputs are stored on a remote device and transmitted to the controller via wireless transmission. In one example, the controller may be a seat Electronic Control Unit (ECU) of the vehicle. Further forms, objects, features, aspects, benefits, advantages, and embodiments of the present disclosure will become apparent from the detailed description and drawings provided herein.

Detailed Description For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. However, it should be understood that no limitation with respect to the scope of the present disclosure is thereby intended. Any alterations and further modifications in the described embodiments, and any further applications of the principles of the disclosure as described herein are contemplated as would normally occur to one skilled in the art to which the disclosure relates. One embodiment of the present disclosure is shown in great detail, although it will be apparent to those skilled in the relevant art that some features not relevant to the present disclosure may not be shown for clarity. Vehicle seating systems may be used to reduce user fatigue and other undesirable effects of long distance travel. Such a system includes a typical vehicle seat mountable in a vehicle, at least two power seat adjustment actuators, and an electrical controller. As an example, various embodiments of the system may be used within an automobile, train, and/or aircraft. The actuator is movable to alter the seating position formed by the seat, thereby reducing positional fatigue of the user. The actuator preferably repositions the seat to a different seating position with a slow moving average typically less than about 10 centimeters per second. The electrical controller has a control period that generally includes at least one movement period and, in some embodiments, at least one fixed period. In an exemplary embodiment, the electrical controller initiates the control period after a first period of time that begins when the vehicle is turned on. Thereafter, the control cycle preferably includes at least one movement cycle in which the actuator automatically cycles through the various seating positions and repositions the user to reduce fatigue for long distance travel.
