A closing device for opening and closing an opening in a vehicle is disclosed. The closing device comprises a closing system, having a closing body (SK) that is fitted on the vehicle (FZ) in a movable manner and is configured to open and close the opening (O), a drive device (AV) that is operatively connected to the closing body (SK) and is configured to move the closing body (SK), and a transmission system (US) that is arranged between the closing body (SK) and the drive device (AV) and is configured to transmit a drive force generated by the drive device (AV) to the closing body (SK). The closing system (SLS) has a closing system spring rate (FRSLS) that characterizes an overall elasticity of the closing body (SLS), of the drive device (AV) and of the transmission system (US). The closing device (SV) also comprises a force transmission spring unit (KUFE) that is configured to pick up the drive force transmitted from the drive device (AV) to the closing body (SK). The force transmission spring unit (KUFE) has a force transmission spring rate (FRKUFE) that is lower than the closing system spring rate (FRSLS).

Closing device for a vehicle

The disclosure relates to a motor vehicle having at least one vehicle side, on which a front door and a rear door are provided, and to a method for operating an electric motor in a respective rear door of the at least one vehicle side. The disclosure relates to a motor vehicle having at least one vehicle side, on which a front door and a rear door are provided, wherein an electric motor configured to provide a motorized door function is provided in the rear door and wherein a control device configured to operate the motor which is connected to the motor via electrical conductor elements for transferring a motor current is provided. According to the disclosure, the control device is arranged in the front door and is configured to also control at least one door function of the front door.

Motor vehicle having a front door and a rear door

A door handle assembly having a vehicle door handle and a vehicle door. The vehicle door handle moves between a first, retracted position, in which an essentially planar surface of the vehicle door handle is flush with an outer face of the vehicle door, and a second, extended position, in which a grip opening between the outer face of the vehicle door and a grip inner side of the vehicle door handle is cleared for a user. The vehicle door handle is movable between the first and second positions aided by an electric motor, controlled by a control unit. The electric motor can be set in rotation starting from the second position of the door handle by application of a user's external force on the basis of a mechanical coupling of the vehicle door handle to the electric motor sensed by a sensing unit and fed to the control unit.

Doorhandle assembly with a vehicle doorhandle

A device for determining the actual reversal of the direction of rotation of a rotational drive continuing to operate after previous switching of the direction of rotation, in particular for window lifting systems or sliding roof drives in a motor vehicle, has a sensor wheel () with a coding structure () configured asymmetrically in respect of distribution along the periphery of the sensor wheel (); a single detector (), which generates a rotor speed-dependent pulse signal during rotation of the sensor wheel () by scanning the coding structure (); and an evaluation unit (), to which the pulse signal is fed and which determines the actual reversal of the direction of rotation by evaluating the pulse edges; wherein the coding structure () is formed by coding sectors () of a first sector width () and a reference coding sector pair () with a second sector width ().
