Abstract
A drive assembly for driving an adjustable unit in a motor vehicle includes a motor/transmission and an associated control unit. The motor/transmission is suitable for adjusting an adjustable part in a motor vehicle for normal applications. The transmission is driven by the motor to adjust the adjustable part. The motor and the transmission are separated by an interface region. The motor includes a magnetic field generator for generating an alternating magnetic field as the motor drives the transmission. The control unit can be readily connected to the motor/transmission for controlling the adjustment of the adjustable part for more advanced applications. To be readily connected to the motor/transmission, the control unit includes a profiled projection having a hollow chamber. A magnetic sensor is positioned inside the hollow chamber. The profiled projection is movable to engage the housing portion surrounding the interface region to move the control unit in an operable position with respect to the motor such that the magnetic sensor detects the magnetic fields generated by the magnetic field generator as the motor is driven for determining the position of the adjustable unit as the adjustable unit is being driven. The position of the adjustable unit is required for more complex applications.
