Abstract

A vehicle maneuver application (VMA) interface, and a VMA interface system software being executed thereon, may be used for installing, modifying, uninstalling, activating, and/or deactivating one or more VMAs. The VMA interface may include an interface processor and an interface memory. The interface processor may be configured to install the VMA to the VMA device upon receiving an installation signal, update the installed VMA upon receiving an update signal, uninstalling the installed VMA upon receiving an uninstallation signal, activating the installed VMA upon receiving an activation signal, and/or deactivating the installed VMA upon receiving a deactivation signal. The interface memory may be coupled to the interface processor, and it may be configured to store a VMA execution record related to the installed VMA.
