<p>A clutch control arrangement in a vehicle is to be capable of being controlled by a clutch pedal and additionally and independently by an automatic free running device. For this purpose, it is proposed that, in addition to a clutch pedal (12), an hydraulic auxiliary piston (2) which is connected to a two-way valve (15) which can be controlled by the automatic free running device and which acts on the means, which actuate a clutch lever (23), such as a column of liquid or a Bowden cable or the like, be provided. The clutch can be opened by means of the hydraulic auxiliary piston (2) independently of the clutch pedal. In order to drive the hydraulic auxiliary piston (2), the two-way valve (15) is actuated with the aid of two electromagnets (18 and 19), one piston-swept volume (7) of the auxiliary piston (2) being connected either by a pressure line (17) to a pressure source or to a discharge line (16). <IMAGE></p> |
