Method for determining the activity of a driver of a motor vehicle and the adaptive response time and a corresponding assistance system
First Claim
1. A method for determining an adaptive reaction time of a driver of a motor vehicle based on an activity of the driver as part of predictive monitoring of surroundings of the motor vehicle by an assistance system, the method comprising:
- sensing the surroundings in front of the motor vehicle by a surrounding sensor system;
determining the driving behavior of the vehicle driving ahead of the driver'"'"'s motor vehicle using the surroundings sensor system;
determining operator control actions of the driver in the motor vehicle;
determining a vehicle-specific driver'"'"'s activity;
determining a correlated driver'"'"'s activity from the interaction between the vehicle driving ahead and reactions of the driver;
determining whether the driver is active based on the vehicle-specific driver'"'"'s activity and the correlated driver'"'"'s activity;
determining a driver'"'"'s reaction time from the resulting driver'"'"'s activity, wherein the driver'"'"'s reaction time varies based on reactions of the driver; and
generating a warning to the driver as a function of the driver'"'"'s reaction time and a distance from the vehicle driving ahead.

Abstract
A method for determining an adaptive reaction time of a driver of a motor vehicle, wherein the adaptive reaction time is determined from the activity of the driver by determining the driving behavior of a vehicle driving ahead by a surroundings sensor system, determining activities of the driver of the motor vehicle, determining chronological correlations between the driving behavior of the vehicle driving ahead and the activities of the driver, and determining the driver'"'"'s activity from the chronological correlations. The method is applied in assistance systems with observation of the surroundings in front of the motor vehicle, in which systems the driver'"'"'s reaction time is used to determine a warning time.
