Abstract

Controlled startup of devices is based on dynamic statistical predictions. Timely startup of onboard associated vehicle devices is based on dynamic statistical predictions and driver proximity to the vehicle. An apparatus for timely startup includes an interface operatively coupled with a power consuming device and control logic coupled with the interface. The control logic is operable in a first mode to perform processing for determining a presence of a first condition of the vehicle, and to selectively activate the power consuming device of the vehicle, via the interface, responsive to determining the presence of the first condition. The control logic is operable in a second mode to suspend, via the interface, the processing for determining the presence of the first condition of the vehicle. The control logic selectively transitions between the first and second modes in accordance with a stochastic modeling of the presence of the first condition over time.
