The present invention relates to a vehicle access system (1) having a tracking means (11; 23, 25, 27) for tracking a positional movement pattern of a user (D) relative to a vehicle (3). A controller (9) is provided for controlling the opening and/or closing of a vehicle opening (5). The controller (9) communicates with a storage device (15) and the tracking means (11; 23, 25, 27). The controller (9) has a comparator (17) for comparing the positional movement pattern with one or more pre-defined movement maps stored in the storage device (15). The controller is configured to open the vehicle opening when the comparator (17) determines that the positional movement pattern corresponds to a first of the pre-defined movement maps. Alternatively, or in addition the controller can be configured to close the vehicle opening when the comparator (17) determines that the positional movement pattern corresponds to a second of said pre-defined movement maps. The invention also relates to a method of opening/closing a vehicle opening.
