Problems solved by technology
However, such a system has the disadvantage that a different transmittable drive torque can no longer be distributed to one drive wheel than the transmittable drive torque assigned to the other drive wheel
Specific adjustments to the yaw moment for influencing the active yaw function or individually adjustable slides for each side are no longer possible
In systems of the kind described in the international patent application PCT / EP2013 / 077248 or in the German laid-open publication DE 4021747 A1, the essentiality provided in principle by a gearless, clutch-controlled differential unit with individually actuatable clutches is thus lost. advantage

Embodiment Construction
[0024] exist figure 1 In , a differential unit 1 and a system for its operation are schematically shown. The characters "L" and "R" assigned to certain reference numerals in the drawings denote left ("L") or right ("R") portions of a partially symmetrical basic structure.
[0025] The drive power of the vehicle drive is transmitted via the input element 2, usually a cardan shaft, and the drive wheel 3 connected to said input element to the ring gear 4, and from the ring gear to the left or right drives the disc carrier 5, left or right drive The disk carriers 5 are each equipped with a drive disk 7 which is arranged so as to be axially displaceable and non-rotatable relative to each other. These drive discs 7 interact with left or right output discs 7 which in turn interact in a relatively non-rotatable manner with left or right output elements 8 and are axially displaceable but non-rotatably arranged on the left or right On the right output disk carrier 9. The left or righ...

The problem addressed by the invention is that of reducing the complexity and the expenditure for development and vehicle application of systems and methods known from the prior art for the operation of a differential-free, clutch-controlled balancing unit comprising a first clutch and a second clutch, without giving up the possibility of assigning different torque to the clutches. This problem is solved in that a manipulated variable originally produced by a manipulated-variable unit is fed to the first clutch unchanged, while the manipulated variable is fed to the second clutch under the condition that an individual control element is interposed. The first and the second clutches have different clutch properties.
Description
technical field [0001] The invention relates to a system for actuating a motor vehicle, in particular a passenger car, of a gearless, clutch-controlled differential unit according to the preamble of claim 1 and to a system according to the preamble of claim 10 Part of the method of controlling this differential unit. Furthermore, the invention relates to a computer program carrier which enables an electronic control unit for controlling such a differential unit to actuate the differential unit according to the method according to the invention and to the control unit itself. Furthermore, the invention relates to a gearless clutch-operated (transverse) differential unit of a motor vehicle, in particular a passenger car. Background technique [0002] Such a differential unit as well as systems and methods for its operation are known, for example, from EP 2116411 A1 or DE 4039391 A1. In this case, two separately actuatable control valves are used in each case to specifically ...
