"The Queen and the Duke of Edinburgh would like to be remembered to you." - what does that mean?

What does “would like to be remembered to you” mean in the statement: “”The Queen and the Duke of Edinburgh would like to be remembered to you.” ?

This was later released by the Royal Household to a member of the public who was injured in the accident also involving Prince Philip’s vehicle.

I should point out that my question is:

• not to pass judgement or assign fault to any party in the accident
• not to pass judgement on a person’s fitness to drive or required use safety facilities whilst driving
• not to debate the need for the Royal Family. From a personal perspective I’m not opposed to them. Sources elsewhere on the internet can do a much better job than myself to point out how the UK benefits from having a Royal Family.

My question is:

• To understand the meaning of the phrase: “would like to be remembered to you.”.

I’m not the only one to observe the peculiar grammar as well to not understand what the message was saying. You’ll find articles on this but I’ve not found one that disects the meaning, hence posting the question here.
