Method for operating a vehicle

Abstract

A method for operating a vehicle, in which the method allows feedback about imminent risks. In this context, the vehicle moves on a predefined route at a current traveling velocity. A value characteristic of the vehicle movement along the predefined route is precalculated as a function of the current traveling velocity and the predefined route. A vehicle function is activated as a function of this value.

       21 . A method for operating a vehicle, which moves on a predefined route at a current traveling velocity, comprising:
 as a function of the current traveling velocity and the predefined route, precalculating a characteristic value for the vehicle movement along the predefined route; and   activating a vehicle function as a function of the characteristic value;   wherein the vehicle function is at least one of a function for occupant protection and a driver information function activated in the form of a haptic feedback.   
   
   
       22 . The method as recited in claim  1 , wherein a precharging of a brake system or a conditioning of at least one restraint system is activated as a function for occupant protection. 
   
   
       23 . The method as recited in claim  1 , wherein the feedback is implemented at an accelerator pedal. 
   
   
       24 . The method as recited in claim  1 , wherein the driver-information function is activated in the form of feedback regarding a forthcoming critical curve or for optimizing one of fuel consumption and exhaust gas. 
   
   
       25 . The method as recited in claim  1 , wherein a yaw rate is selected as the characteristic value. 
   
   
       26 . The method as recited in claim  1 , wherein the calculation of the characteristic value assumes that an accelerator pedal of the vehicle is not operated. 
   
   
       27 . The method as recited in claim  1 , wherein the route is predetermined in the form of a set of route points, and a path between the route points is interpolated with the aid of continuous and differentiable functions. 
   
   
       28 . The method as recited in claim  1 , wherein the characteristic value is determined as a function of a steering angle, and the steering angle is determined as a function of a traveling-direction vector and a vector tangent to the traveling direction. 
   
   
       29 . The method as recited in claim  8 , wherein the traveling-direction vector is ascertained as a function of a radian measure of the predefined route, and the radian measure is ascertained from a range of the vehicle. 
   
   
       30 . The method as recited in claim  9 , wherein the range of the vehicle is ascertained as a function of a vehicle acceleration, and the vehicle acceleration is ascertained with the aid of a pulling-force equation.
