Abstract
A method for influencing the load on a driver while driving a motor vehicle, in which a workload is determined from physiological driver data detected by sensors, and to an apparatus for carrying out the method. The load or the workload on the driver is kept in an optimum workload range and brought back to this optimum range if there is any discrepancy, thus ensuring an optimum driver performance level and attention level. For this purpose, vehicle systems are driven as a function of the detected workload value in such a way that the driver is influenced via his visual, auditory or tactile sense channels in such a way that his workload value returns to a value in the optimum workload range.

41. A method for influencing the load on a driver while driving a motor vehicle, comprising the steps:
-
determining a workload (WL), from physiological driver data detected by means of sensors, comparing the determined workload (WL) with a predetermined intended workload (WLopt), if the determined workload (WL) is less than the predetermined workload where WL<
WLopt indicates that the driver is underloaded, increasing the load on the driver by at least one of producing at least on of visual and audible and tactile and olfactory signals by controlling at least one vehicle system, and by increasing at least one of visual and audible and tactile and olfactory signals which have already been produced, and by changing their signal quality by controlling at least one vehicle system, andif the determined workload (WL) is greater than the predetermined workload where WL>
WLopt the driver is overloaded, preventing any increase in the load on the driver by at least one of providing driver information and display systems in the motor vehicle in such a way that the output of at least one of visual and audible and tactile and olfactory signals is completely suppressed or partially suppressed or output at a later time. - View Dependent Claims (44, 45, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80)
