A sudden-acceleration case against Toyota Motor Corp. is headed for settlement, a turn of events that would call off a bellwether trial against the automaker scheduled for next month.

The case is the first of the consolidated sudden-acceleration lawsuits claiming personal injury against Toyota set for trial. It was brought by the family of Paul Van Alfen, a 66-year-old Utah resident who was killed three years ago while driving a 2008 Camry.
