Embodiment Construction

[0032] The examples described in detail below are preferred embodiments of the present invention.

[0033] figure 1 A motor vehicle 10 is shown which has a control unit 12 . Control unit 12 is connected via corresponding data lines to wheel speed sensors 14a to 14d of the wheels of the motor vehicle. Furthermore, the control device 12 is connected to a steering angle sensor 16 , which is operatively connected to the steering system of the motor vehicle. Control unit 12 is designed to determine at least one state variable of motor vehicle 10 from the data of wheel speed sensors 14 a to 14 d and from the data of steering angle sensor 16 . Such state variables can be, for example, speed, acceleration, direction of travel, etc. The motor vehicle can have further sensors, not shown here, with which other state variables of motor vehicle 10 can be determined.

[0034] Furthermore, the controller 12 is designed to detect a predetermined driving maneuver from the temporal profile ...

Abstract

The invention relates to a method for controlling a reversible belt tensioner (18) of a safety belt in a motor vehicle (10) by detecting a progression over time of at least one state variable and / or at least one variable relating to the surroundings of the motor vehicle, recognising a predetermined driving manoeuvre and / or a value characterising the attentiveness of a driver by means of the progression over time of the at least one detected state variable and / or variable relating to the surroundings, and controlling the reversible belt tensioner (18) on the basis of the recognised driving manoeuvre or on the basis of the value characterising the attentiveness of the driver.

Description

technical field [0001] The invention relates to a method for controlling a reversible seat belt retractor of a seat belt in a motor vehicle. Furthermore, the invention relates to a driver assistance system for a motor vehicle. Finally, the invention relates to such a motor vehicle. Background technique [0002] Current motor vehicles are equipped with conventional seat belt systems without reversible seat belt retractors or with seat belt systems with reversible seat belt retractors. In a motor vehicle equipped with a reversible seat belt tensioner, when starting to drive with the seat belt inserted, the seat belt is tightened and a so-called slack state of the seat belt is avoided. During driving, however, the seat belt slack is reintroduced into the respective seat belt system due to movements of the driver or vehicle occupants or due to corresponding driving maneuvers. As a result, the seat belt is no longer sufficiently tightened and the driver or other vehicle occupa...
