Abstract: A method for fault tolerant controller readiness. Executing functions by a first controller operating in a primary status mode. Operating in a hot standby status mode by a second controller and mirroring the first controller by executing functions to operate as a redundant controller. Operating in a cold standby status mode by at least one backup controller under normal operating conditions. The second controller is reconfigured while operating under normal operating conditions from the hot standby status mode to the primary standby status mode if a failure occurs in the first controller. Reconfiguring the at least one backup controller operating under normal operating conditions from cold standby status mode to hot standby status mode to operate as a redundant controller in response to the reconfiguring the second controller from the hot standby status mode to the primary status mode.

Abstract: A method of controlling data communication between a vehicle and a plurality of wireless networks includes tracking a location of the vehicle over time to identify a known route, and tracking a signal duration for each of the plurality of wireless networks. One of the plurality of wireless networks that provides the longest signal duration for the vehicle, and which is available for data communication with the vehicle along the identified known route, is identified. When a current route of the vehicle is the same as the known route, data communication from the vehicle is connected to the available wireless network identified as providing the longest signal duration for the vehicle when moving along the identified known route.
