Yvonne Talbott's scooter crashed with a BMW X5 on the Roanne Ringway in Nuneaton last Sunday. She died the following day.
Her family said: "It will be impossible to fill the void that is left.
"She was dearly loved by the further four generations of her family that she leaves behind."
Anyone who witnessed the crash or who saw either vehicle beforehand is urged to contact Warwickshire Police on 101.
Relatives of an 84-year-old woman who died after her mobility scooter crashed with a car have described her as the "anchor to our family".
