    Abstract: Methods and systems to implement sensor fusion to determine collision potential for a vehicle include identifying a specific intersection that the vehicle is approaching, and identifying collision potential scenarios associated with one or more paths through the specific intersection. Each collision potential scenario defines a risk of a collision between the vehicle and an object in a specified area. A weight with which one or more information sources of the vehicle are considered is adjusted for each collision potential scenario such that a highest weight is given to one or more of the one or more information sources that provide most relevant and reliable information about the specified area. Sensor fusion is implemented based on the adjusting the weight of the one or more information sources and performing detection based on the sensor fusion, and an alert is provided or actions are implemented according to the detection.

    Abstract: An example of a negative electrode includes silicon nanoparticles having a carbon coating thereon. The carbon coating has an oxygen-free structure including pentagon rings. The negative electrode with the silicon nanoparticles having the carbon coating thereon may be incorporated into a lithium-based battery. In an example of a method, silicon nanoparticles are provided. A carbon precursor is applied on the silicon nanoparticles. The carbon precursor is an oxygen-free, fluorene-based polymer. Then the silicon nanoparticles are heated in an inert gas atmosphere to form the carbon coating on the silicon nanoparticles. The carbon coating formed on the silicon nanoparticles has an oxygen-free structure including pentagon rings.

    Abstract: A method for monitoring a battery module in a vehicle includes selecting an upper cut-off voltage and a lower cut-off voltage for the battery module. The method includes charging the battery cell from an original state to a first benchmark voltage greater than an upper cut-off voltage, via a first charging process. The method includes discharging the battery cell from the first benchmark voltage to a second benchmark voltage less than a lower cut-off voltage, via a first discharging process. The battery module is then charged from the second benchmark voltage to the first benchmark voltage, via a second charging process. The method includes obtaining a ratio of a discharging capacity to a charging capacity of the battery module. Operation of the vehicle is controlled based in part on the ratio, including taking at least one remedial action if the ratio is less than a predefined threshold.

    Abstract: A system for key absence management in a vehicle configured to be started by an electronic key fob includes a key absence management controller that implements a method configured to authorize starting of the vehicle by monitoring presence and absence of the electronic key fob in the vehicle. If the controller finds the electronic key fob to be present in the vehicle, then the controller authorizes starting of the vehicle. If the controller finds the electronic key fob to be absent from the vehicle, then the controller authorizes starting of the vehicle based on detection of a keyless authority indicator. A vehicle configured to be started by an electronic key fob includes the system with the controller that implements the method.

    Abstract: Excessive expansion of rechargeable batteries during recharging is a significant concern since the uncontrolled buildup of high internal battery pressures from expansion inside a confined space can lead to separator membrane failure and/or thermal runaway of a battery cell. A crushable foam or honeycomb insert layer is placed inside of a rigid battery fixture to automatically limit the progressive buildup of internal battery pressure due to charging-induced expansion of the battery cell during recharging. The crushable insert layer is included as part of the rigid battery fixture. Aluminum honeycomb cores and porous aluminum metal foam materials have a significant amount of crushability over a very wide range of compressive strains. Alternatively, a porous metal foam or metal honeycomb material may be infused with a liquid polymer (e.g., silicone, rubber, EDPM, or polyurethane) to enhance the mechanical properties of the polymer-infused metal foam or honeycomb metal/polymer composite material.
