Method and devices for disabling detection of a safety system activation
condition. One embodiment of the invention provides a method that
includes disregarding information from a first set of sensors when
detection of a safety system activation condition is disabled;
determining if information from a second set of sensors in available;
when information from a second set of sensors is not available,
generating a warning signal; when information from the second set of
sensors is available, determining a value of the information from the
second set of sensors; and when the value of the information from the
second set of sensors indicates that a vehicle is in use, enabling
detection of the safety system activation condition.
