Problems solved by technology

[0004] Due to the fact that drive motors with drive units have different tolerances as drive units, the transmission ratios vary from drive unit to drive unit within the tolerance distribution, which complicates the application of such drive units
Especially under changing external conditions the influence on the tolerances is large, so the adjustment speed can vary greatly, which is not a desired situation

Embodiment Construction

[0034] figure 1 Shown is a partial perspective view of a motor vehicle 1 with a drive unit 2 according to the invention for adjusting or operating an air guide element 3 (eg a rear spoiler). The air guide elements here can also be other air guide elements, such as front spoilers or the like.

[0035] The drive unit 2 for adjusting the air guide element 3 of the motor vehicle 1 has a drive motor with at least one transmission, which is connected to the drive motor to form a combined unit and forms a drive motor-gear unit, wherein The drive motor-gearing unit has a rotatable shaft 4 on its two axial end regions, which can be driven by at least one transmission in order to adjust the air guide element 3 .

[0036] In this case, the corresponding shaft 4 drives a mechanism 5 which actuates levers 6 arranged thereon on both sides of the air guide element in order to raise and lower the air guide element 3 .

[0037] figure 2 Shown is an embodiment of a drive unit 10 according t...

Abstract

The invention relates to a drive unit (2, 10, 20, 51), in particular an air guide element (3) for a motor vehicle (1), with a drive motor (11, 21, 52, 129), which The drive motor has at least one transmission mechanism (12, 22, 23, 53), which is connected with the drive motor (11, 21, 52, 129) to form a combined unit and constitutes a drive motor-transmission mechanism unit, in which the drive A control unit (54) for controlling the driving unit (2, 10, 20, 51) is arranged in the unit (2, 10, 20, 51), and a detection driving unit (2, 10, 20, 51) is arranged ) temperature temperature sensor (60).

Description

technical field [0001] The present invention relates to a drive unit and a method of controlling a drive unit, in particular for an air guide element of a motor vehicle. Background technique [0002] Known air-guiding elements on motor vehicles are spoiler elements, which protrude or adjust as a function of the driving state or driving speed. For example, it is known that a rear spoiler retracts when the vehicle is traveling at low speeds and extends upon reaching a predetermined travel speed to increase downforce. [0003] DE 10 2013 100 518 A1 discloses a drive motor arrangement, which is coupled via two drive shafts to a corresponding drive mechanism connected to it, wherein the power take-off shaft of the respective drive mechanism is connected to the rear spoiler. Adjustment kinematics are connected. [0004] Since the drive motors of the belt transmission mechanism respectively have different tolerances as the drive units, the transmission ratios between the drive un...
