Abstract: A system and method for assisting vehicle parking is disclosed. The method includes transmitting, by an electronic controller of a vehicle, a parking space request. The parking space request is transmitted to a reservation system. The reservation system determines whether a parking space is available to fulfill the parking space request. The determining is based on availability information that is received from a parking infrastructure. The method also includes receiving an indication. The indication indicates whether a parking spot has been reserved to fulfill the parking space request.
