Abstract
A help system is provided for a vehicle occupant who carries a mobile communication device. The vehicle has a transceiver providing two-way wireless telecommunication and which detects a loss-of-signal condition. A powertrain system provides vehicle movement and is configured for reckoning a path traversed by the vehicle. The help system includes a guidance controller and an interface adapted to connect to the mobile communication device. The guidance controller is configured to A) identify a crossing point when the transceiver detects an initiation of the loss-of-signal condition, B) store a breadcrumb route for returning to the crossing point based on the reckoned path, C) detect a stranded condition of the vehicle during the loss-of-signal condition, D) generate guidance instructions including the breadcrumb route from the vehicle back to the crossing point when the stranded condition is detected, and E) transfer the guidance instructions to the mobile communication device.
