1. A method for controlling a driver assistance system in a vehicle, the method comprising:
- recognizing, by a control unit using a sensor, a driver of the vehicle;
detecting, by the control unit, an activating request for a driver assistance system from the recognized driver;
ascertaining, by the control unit, a value based on an assessment of a driving behavior of the recognized driver in operating the vehicle while the driver assistance system of the vehicle is in an active state, wherein the driving behavior comprises at least one of a braking operation, an acceleration operation, a shifting operation, an operation modifying a regulated distance, and a failure to retake control of vehicle guidance upon return of responsibility from an automatic function to the driver;
comparing, by the control unit, the ascertained behavior-based value to a threshold value determined and stored based on rules and parameters established for the driving behavior;
determining, by the control unit, after the detection of the activating request and based on the comparison, whether the recognized driver of the vehicle is suitable for utilizing the requested driver assistance system; and
controlling the requested driver assistance system depending on the determined suitability of the recognized driver for utilizing the requested driver assistance system, wherein the controlling is performed such that;
(i) when the ascertained behavior-based value is greater than the threshold value, the driver is determined to be suitable for utilizing the requested driver assistance system, and the driver assistance system is allowed to be in the active state; and
(ii) when the ascertained behavior-based value is not greater than the threshold value, the driver is determined to be unsuitable for utilizing the requested driver assistance system, and the requested driver assistance system is prevented from being in the active state.

13. A control system for controlling a driver assistance system of a vehicle, the control system comprising:
-
a sensor; a control unit, wherein the control unit is configured to recognize a driver of the vehicle based on output of the sensor; and an input device via which an activating request for a driver assistance system is inputtable by the recognized driver, wherein the control unit is configured to; ascertain a value based on an assessment of a driving behavior of the recognized driver in operating the vehicle while the driver assistance system of the vehicle is in an active state, wherein the driving behavior comprises at least one of a braking operation, an acceleration operation, a shifting operation, an operation modifying a regulated distance, and a failure to retake control of vehicle guidance upon return of responsibility from an automatic function to the driver; compare the ascertained behavior-based value to a threshold value determined and stored based on rules and parameters established for the driving behavior; determine, after the detection of the activating request and based on the comparison, whether the recognized driver of the vehicle is suitable for utilizing the requested driver assistance system; and control the requested driver assistance system depending on the determined suitability of the recognized driver for utilizing the requested driver assistance system, the control being such that; (i) when the ascertained behavior-based value is greater than the threshold value, the driver is determined to be suitable for utilizing the requested driver assistance system, and the driver assistance system is allowed to be in the active state; and (ii) when the ascertained behavior-based value is not greater than the threshold value, the driver is determined to be unsuitable for utilizing the requested driver assistance system, and the requested driver assistance system is prevented from being in the active state.

14. A non-transitory computer-readable data storage medium storing a computer program having program codes which that are executable by a computer and that, when executed on the computer, cause the computer to perform a method for controlling a driver assistance system in a vehicle, the method comprising:
-
recognizing, by a control unit using at least a sensor, a driver of the vehicle; detecting, by the control unit, an activating request for a driver assistance system from the recognized driver; ascertaining, by the control unit, a value based on an assessment of a driving behavior of the recognized driver in operating the vehicle while the driver assistance system of the vehicle is in an active state, wherein the driving behavior comprises at least one of a braking operation, an acceleration operation, a shifting operation, an operation modifying a regulated distance, and a failure to retake control of vehicle guidance upon return of responsibility from an automatic function to the driver; comparing, by the control unit, the ascertained behavior-based value to the a threshold value determined and stored based on rules and parameters established for the driving behavior; determining, by the control unit, after the detection of the activating request and based on the comparison, whether the recognized driver of the vehicle is suitable for utilizing the requested driver assistance system; and controlling the requested driver assistance system depending on the determined suitability of the recognized driver for utilizing the requested driver assistance system, wherein the controlling is performed such that; (i) when the ascertained behavior-based value is greater than the threshold value, the driver is determined to be suitable for utilizing the requested driver assistance system, and the driver assistance system is allowed to be in the active state; and (ii) when the ascertained behavior-based value is not greater than the threshold value, the driver is determined to be unsuitable for utilizing the requested driver assistance system, and the requested driver assistance system is prevented from being in the active state.
