  • Method for use with vehicle having selectable transfer case
    Patent number: 9358883
    Abstract: A method for notifying, indicating or otherwise alerting a driver when it may be desirable to switch to a different transfer case mode. According to an exemplary embodiment, the method uses one or more environmental and/or vehicle conditions to evaluate a current transfer case mode and to determine if it is the most preferable or optimal mode. If the current transfer case mode is not optimal, then the method may recommend that the driver manually switch transfer case modes by notifying or alerting them through a visual and/or audio message. In one example, the method recommends a transition from a four-wheel mode to a two-wheel mode, or vice-versa, with a visual message on an instrument panel gauge.
