A method for an access system for a vehicle includes the steps of recording a first optical information in a specific area surrounding the vehicle and detecting an object approaching the vehicle as a function of the recorded first optical information. As a function of detecting the approaching object, a second optical information in the surrounding area is recorded, and gesture information of the object is identified as a function of the second optical information. A locking device or door opening device of the access system is triggered as a function of gesture information.
