  • The The invention relates to an arrangement for a vehicle and a method for placing a vehicle rearview mirror when cornering with in the preamble of claims 1 and 10 mentioned features.
  • From the DE 41 09 315 A1 is a motor vehicle rearview mirror with automatic extension of a reflection range of the vehicle rearview mirror known. The extension of the reflection range is effected in that the motor vehicle rearview mirror is connected to adjustment means which pivot the motor vehicle rearview mirror in response to a direction indicator operation.
  • By the automatic extension of the reflection area can be a driver's field of view when cornering in a blind spot to be pivoted.
  • Inside- and outside mirrors of a motor vehicle are important means by which a driver can use a Done in the traffic in a rear area of the motor vehicle can inform.
  • According to the invention, it has been recognized that mirror fields of vision of a driver are noticeably changed already at a vehicle speed of 40 km / h. In doing so, changing the driver's field of view contributes to the following factors:
    • - The vehicle undergoes a transverse acceleration in a curve, which causes a rolling movement of the motor vehicle, that is, a tilting of the vehicle about a vehicle longitudinal axis. By this rolling motion creates an angle between a vehicle floor and a road level, hereinafter referred to as vehicle roll angle.
    • - The driver tends when driving a curve his upper body for better driving control when turning the steering wheel to the inside of the curve.
    • - By acting on the driver's upper body while driving a curve lateral acceleration bends the upper body of the driver towards the inside of the curve.
  • These Three factors together cause a shift of one through a vehicle mirror detectable rear field of view depending on the curve orientation to the left or right. As a result, the rear field of view is so moved that parts of an event, in an area behind the motor vehicle, are no longer detected by the driver visually can.
  • Of the Invention is therefore based on the object, the driving safety Driving a curve to improve.
  • These The object is achieved by an arrangement of the type mentioned, wherein the arrangement is formed, the position of the mirror plane with the Adjusting device at least in response to a vehicle rolling movement, in particular a vehicle rolling motion about a vehicle longitudinal axis or a vehicle pitching movement about a vehicle transverse axis or of both, to change.

  • In a preferred embodiment the arrangement has a steering angle sensor, which is formed is to detect a turning radius of a cornering of the vehicle and to generate a Kurvenradiussignal corresponding to the curve radius. The Arrangement is in this embodiment formed, the position of the mirror plane by means of the adjusting device dependent on from the Kurvenradiussignal to change. By capturing a Kurvenradiussignals can be advantageously detected, whether a roll angle a vehicle is caused by cornering.
  • Further Preferably, the arrangement has a speed sensor, which is designed to detect a vehicle speed and a speed signal corresponding to the vehicle speed to create. The arrangement is formed in this embodiment, the location the mirror plane by means of the adjusting device in dependence on to change the speed signal.
  • Further Advantageously, the arrangement can be designed, a ratio signal to generate what a ratio, formed from the speed signal and the Kurvenradiussignal, equivalent. The arrangement is formed in this embodiment, the Position of the mirror plane by means of the adjusting device in dependence from the ratio signal to change. For example, such a ratio signal may be the ratio of Represent vehicle speed divided by the radius of curvature.
  • In this embodiment For example, one caused by a lateral acceleration Movement of an upper body a driver - for example empirically determined - at an adjustment of a vehicle rearview mirror be taken into account.
  • In advantageous embodiment the arrangement has a head position sensor which is formed is to detect a driver's head position and a head position generate corresponding head position signal. In this embodiment the arrangement is formed, the position of the mirror plane by means of the adjusting device in dependence from the head position signal.
  • One Head position sensor may be a distance sensor, which is a Distance to a driver head interferometric or by radiation transit time difference can capture.
