Method for detecting and preventing a relay attack on a transaction that can be carried out by means of contactless data transmission between a data carrier and a terminal device, wherein a transaction signal sent by the data carrier to the terminal device for carrying out the transaction comprises supplementary information which enables the terminal device to detect a relay attack, comprising the further steps:- evaluating the supplementary information by the terminal device; and- carrying out the transaction by the terminal device in the case that a relay attack can be ruled out on the basis of the evaluation of the supplementary information, characterised by the further steps:- sending a confirmation request signal by the terminal device to the data carrier in the case that a relay attack cannot be ruled out on the basis of the evaluation of the supplementary information; and- carrying out the transaction by the terminal in the event that a transaction confirmation signal from the data carrier is received within a predetermined transaction confirmation interval, or by the further steps:- sending a confirmation request signal by the terminal to the data carrier in the event that a relay attack cannot be ruled out on the basis of the evaluation of the supplementary information; and- aborting the transaction by the terminal in the event that no transaction confirmation signal from the data carrier is received within a predetermined transaction confirmation interval or that a transaction abort signal from the data carrier  is received.

The invention relates to a method of utilizing the relative position of a user to a vehicle. The method is characterized in that the use comprises the determination of position data of the relative position of the user relative to a vehicle, in which by means of at least two receiving units (100) on the vehicle and at least one transmitter (12), which is assigned to the user, position data are determined which indicate the approach of the user to the vehicle and the position information containing information about the area of the vehicle to which the smallest distance exists. In addition, a utilization system is described.

A system for controlling driving modes of a vehicle having a driver, where each of the driving modes is adapted to control a behaviour of the vehicle during operation of the vehicle in the driving mode, each of the driving modes being associated with a set of driving sub-modes. Each driving sub-mode is adapted to be activated by the vehicle in response to ambient circumstances. One of the driving modes is associated with a first and a second driving sub-mode, the first and second driving sub-modes being accompanied with a first and a second driver controlled setting respectively. The system also includes an input device for selection between the driving modes and for controlling the driver controlled settings. The first and second driver controlled settings are adapted to be manually set by the driver through the input device only upon activation of the accompanying driving sub-mode by the vehicle.

The present invention relates to a system for driver-vehicle interaction in a vehicle. The system comprises a soft key arrangement which is adapted to be located in the proximity of a steering wheel of said vehicle and having at least two soft keys. Each soft key corresponds to a display key on a display key arrangement having a corresponding layout as said soft key arrangement, said display key arrangement being adapted to be located in the proximity of a dashboard of said vehicle. Said vehicle is associated with at least two function modes in a first set of function modes, each function mode being associated with a set of selectable options in order to affect a behaviour of the vehicle in each function mode, each function mode further being associated with a respective layout for said display key arrangement in order to display said set of selectable options. For each function mode layout, each display key is adapted to illustrate and correspond to a currently available selectable option of said set of selectable options for each soft key, such that actuation of said soft key arrangement is adapted to both effectuate change between said function modes and to select at least one of said currently available selectable options associated with the chosen function mode. The present invention further relates to a vehicle having such a system for driver-vehicle interaction.
