1. A system for automatic control of entry and/or motor starting authorization of a user for a motor vehicle, the system comprising:

  • a control device that controls at least one function of unlocking/locking one or more entry doors of the motor vehicle and/or enabling/disabling a motor control device adapted for controlling operation of a motor of the motor vehicle; and

    an electronic key associated with the control device,wherein the control device and the electronic key each include a transceiver for sending and receiving signals,wherein at least one signal transmitted from the electronic key to the control device is an encoded signal for authentication of the electronic key so that, after evaluation of the encoded signal, given an authorized electronic key, the control device produces a control signal for unlocking one or more of the entry doors and/or for enabling of the motor control device,wherein the control device is configured for at least one of;

    computing, after receiving the encoded signal for an authorized electronic key, by at least one statistical computation method using one or more pieces of information available to the control device able to be used as an indication for computation of a probability of misuse of the electronic key for obtaining an entry and/or motor starting authorization for the motor vehicle, and, in response to the computed probability of misuse reaching or exceeding a prescribable threshold value, stopping at least one control signal for unlocking one or more of the entry doors and/or for enabling of the motor control device or producing the at least one control signal only in response to at least one additional authentication criterion being satisfied, wherein the one or more pieces of information include at least one of;

    a time of a last stoppage of the motor of the motor vehicle;

    a time of a last start of the motor of the motor vehicle;

    a time of a last locking of the one or more entry doors;

    a time of a last unlocking of the one or more entry doors;

    a time of a last disabling of the motor control device;

    a time of a last enabling of the motor control device;

    which of the one or more entry doors that was used last;

    an approximate position of the electronic key in an interior of the motor vehicle before a last start of the motor of the motor vehicle;

    times of regularly made journeys; and

    regular times of nonuse of the motor vehicle; and

    deactivating the system for control of the entry and/or motor starting authorization in response to the control device using at least one statistical computation method to establish that the motor vehicle is parking in an environment in which the probability of future misuse of the electronic key reaches or exceeds a prescribable threshold value based on current parking coordinates of the motor vehicle and at least one further criterion associable with the parking coordinates.
