Mark Warburton's men sit seven points clear of third-placed Leyton Orient with four games remaining, knowing that victory over Preston combined with defeat for Orient and Rotherham United failing to win would see them return to the second tier for the first time since 1993.
Brentford were denied promotion last season by a stunning last-minute defeat to Doncaster Rovers, before another loss to Yeovil Town in the play-off final compounded their misery.
"They learned from last year. They've moved on from last year," he told TheEvening Standard.
"Our target, in a non-arrogant way, is to win four out of four, to secure promotion."
Facing an in-form Preston side will not be easy, though, and Simon Grayson's men could still catch their opponents should they secure victory at Griffin Park.
Peterborough United's return to form has boosted their hopes of a top-six finish and they travel to Bradford City, while Swindon Town, in seventh, will look to keep the pressure on Darren Ferguson's side when they visit Coventry City.
Though manager Graham Westley has not led his side to victory in eight games, they are just four points behind 20t-placed Notts County, who will hope that a run of four wins from five can be improved further at Bristol City.
