Method and system for satelite connection interruption prevention

摘要

A vehicle, such as a car, includes an airbag deployment system and a vehicle systems controller. The vehicle systems controller can connect the airbag deployment system to a reserve power source for a predetermined period of time when a battery terminal voltage falls below a predetermined threshold.

1. A method for controlling electronic systems in a vehicle having a stop-start engine feature comprising the steps of:
monitoring a voltage of a first battery terminal, connected to an electric system through at least one in-line electronic device, during a stop-start event, and thereby determining when the voltage falls below an autarky threshold; altering the autarky threshold by reducing a detected voltage of the first battery terminal by a predetermined voltage reduction amount, the predetermined voltage reduction amount is at least a voltage drop of the at least one in-line electronic device, using a voltage compensator; and connecting the electronic system to a reserve energy source for a predetermined period of time when said reduced voltage falls below said autarky threshold.
