The method and system for automatically controlling a path of travel of a
vehicle include engaging an automatic control system when the security of
the onboard controls is jeopardized. Engagement may be automatic or
manual from inside the vehicle or remotely via a communication link. Any
onboard capability to supersede the automatic control system may then be
disabled by disconnecting the onboard controls and/or providing
uninterruptible power to the automatic control system via a path that
does not include the onboard accessible power control element(s). The
operation of the vehicle is then controlled via the processing element of
the automatic control system. The control commands may be received from a
remote location and/or from predetermined control commands that are
stored onboard the vehicle.
