Abstract

A driver-assistance system for a motor vehicle includes a recording device for recording an environment of the motor vehicle including a rear environment of the motor vehicle, a warning device for generating a warning signal, and an evaluation device. The evaluation device is configured to analyze a current driving behavior of the driver on the basis of the recorded environment of the motor vehicle, and to induce the warning device to generate a warning signal if the evaluation device detects a deviation of the driving behavior from a predetermined setpoint behavior.

Claims

1. An assistance system for a motor vehicle, comprising:

a recording device of the motor vehicle configured to optically record a rear environment of the motor vehicle, the recording device recording images of a traveled trajectory of the motor vehicle including at least a first traveled trajectory portion corresponding to a first time period and a second traveled trajectory portion corresponding to a second time period more recent than the first time period;

a warning device configured to generate a warning signal;

a device configured to determine a current geographical location of the motor vehicle; and

an evaluation device configured to;

(a) analyze a driving behavior of a driver of the motor vehicle on the basis of (i) a comparison of driving behaviors derived from at least the characteristics of the first and second traveled trajectory portions, wherein a setpoint driving behavior is derived from at least the characteristics of the first traveled trajectory portion and a current driving behavior is derived from at least the characteristics of the second traveled trajectory portion, and (ii) the determined current geographical location of the motor vehicle, wherein the evaluation device is configured to estimate a course of a road to be traveled based on the first and second traveled trajectory portions; and

(b) induce the warning device to generate a warning signal if the evaluation device detects a deviation of the current driving behavior from the setpoint driving behavior.

2. The assistance system as recited in claim 1, wherein the warning device is configured to generate the warning signal at least one of optically, acoustically and haptically.

3. A method for providing automated driving-assistance to a driver of a motor vehicle, comprising:

optically recording, using a recording device configured to record a rear environment of the motor vehicle, images of a traveled trajectory of the motor vehicle including at least a first traveled trajectory portion corresponding to a first time period and a second traveled trajectory portion corresponding to a second time period more recent than the first time period;

determining a current geographical location of the motor vehicle;

analyzing a driving behavior of the driver on the basis of (i) a comparison of driving behaviors derived from at least the characteristics of the first and second traveled trajectory portions, wherein a setpoint driving behavior is derived from at least the characteristics of the first traveled trajectory portion and a current driving behavior is derived from at least the characteristics of the second traveled trajectory portion, and (ii) the determined current geographical location of the motor vehicle, wherein the analysis of the driving behavior further includes estimation of a course of the road to be traveled based on the first and second traveled trajectory portions; and

generating a warning signal if a deviation of the current driving behavior from the setpoint driving behavior is detected.

4. The method as recited in claim 3, wherein the warning signal is generated at least one of optically, acoustically and haptically.
