The 38-year-old from Worksop, who was world number one for a five-week spell last year, said he had his eyes set on the US Masters in April.
Westwood was at Buckingham Palace today to receive the honour which was awarded to him in the New Year Honours List.
"Hopefully I'll win it," he said of his Masters aspirations.
"I think this year could be it. I'm certainly playing well enough and getting my game together.
"I've been working hard and putting in a lot of preparation, so hopefully all that will click into place."
Westwood, who has recently returned from three weeks of tournaments in the Middle East and is about to travel to the US, said: "The Queen spoke to me about travelling, where I've been recently and where I'm going.
"I'm sure I don't do as much travelling as she does though.
"I've played golf with Prince Andrew before, so perhaps the Queen has an interest - I would have preferred to speak to her about horseracing though, but I didn't have the chance."
He said of the honour: "It's amazing really. I can't quite believe it.
"You don't imagine, when you start playing the sport you love, that you will end up receiving an award for it. It's amazing really."
