Abstract: A hydraulic power steering system has a servo valve which is arranged between the delivery and suction side of a hydraulic pump. The servo valve is open in the central or normal position and controls the pressure to at least one connection of a hydraulic servomotor. When an operating element of the power steering system is actuated, the servomotor serves to generate a servo positioning force which facilitates the adjustment of the operating element. The hydraulic pump has a drive which can be switched-off, or can be switched over to an extremely low capacity or standby operation, when no servo positioning force is required.

Abstract: An adjusting device having a multi-function operating switch is provided. The function elements which can be controlled by the operating switch can be selected in a variable manner on the user side from a totality of function elements. In a motor vehicle, the operating switch may, for example, have the configuration of a tunnel driving switch by which function elements that can be selected by the user, such as window lifting mechanisms, low-beam and interior-light units, etc. can be controlled into function positions which can also be predetermined by the user for driving through tunnels. This implements a high operating comfort for the individual and situation-adapted adjustment of a condition which can be influenced by a totality of function elements.

Abstract: The invention provides a process for diagnosing defects in an exhaust gas recirculation device of an internal-combustion engine system having an engine timing gear with a knock control. According to the invention, the firing point is advanced until a predetermined minimal knock control displacement is reached, at a time when the engine is operating in steady-state conditions and the exhaust gas recirculation device is active. Subsequently, the exhaust gas recirculation rate is reduced while the advanced firing point is maintained, and it is determined whether the knock control frequency or the knock control displacement change. If not, a defect in the exhaust gas recirculation device is concluded.

Abstract: An exhaust butterfly in an exhaust conduit of an internal combustion engine is supported by way of bearing journals by positive plug-in connections. To simplify installation, the bearing journals and the bearing sleeves are designed in such a way that, to install the exhaust butterfly, the bearing journals are each pressed completely into the respective bearing sleeves counter to the force of a spring. In the case of a multiflow exhaust line, between adjacent exhaust lines cylindrical transverse passages are provided in each of which a driver is rotatably mounted. At one end, the driver has a recess which is designed as a bearing sleeve and into which the bearing journal of the first exhaust butterfly is inserted to produce a driving connection. The other end of the driver is designed as a bearing journal which is likewise inserted into a recess in the second exhaust butterfly to produce a driving connection.

Abstract: A veneer for the veneering of especially curved surfaces has a face veneer formed from thin veneer sheets. The veneer sheets are adhesively bonded along their edges so as to be butted flush and on the side opposite the visible side to a mock veneer which is arranged underneath and which extends over the entire region of the face veneer. To maintain the relative movability between the veneer sheets and the mock veneer, an adhesive is coated on underneath the veneer sheets and is influenced in its setting reaction. In terms of the setting reaction, the adhesive is still reactive over a particular timespan. Thus, when the veneer is finally applied, the adhesive does not tear apart at the joints during a shaping curvature of the veneer because the adhesive in the joint region of adjacent edges of the veneer sheets is set completely.

Abstract: A method for assisting the driver of a vehicle in the optimum use of the on-board energy supply, by consumption-oriented driving-power limitation, especially for electric vehicles. A permissible consumption rate related to the remaining distance is determined continuously starting from the available energy supply and this section consumption is used, taking into account the driving resistances, to determine a set point value which controls a device for driving-power limitation. In a preferred embodiment, an electronic accelerator pedal is provided, with a pedal travel divided into two angular ranges, the second angular range requiring an increased actuating force and being allocated to a power range inhibited in accordance with the set point value. The division into the two angular ranges is adjustable by means of a positioning motor as a function of the permissible section consumption.

Abstract: A mirror housing for an exterior rear-view mirror on a vehicle exhibits a mirror face received in an opening and directed towards the vehicle tail. The mirror housing also exhibits a water channel which runs around the mirror housing adjacent to the opening, which water channel is integrated into the mirror housing opposite the housing surface with side walls sunk in with respect to said housing surface, and by means of which water which impinges in a drive mode is collected before it reaches the opening and is channelled in the direction of the lower housing edge. The mirror housing terminates, between the lower opening border and the water channel, in a strip which is oriented, at an angle with respect to the housing surface, in the direction of the tail and downwards.

Abstract: A method sets the braking effect of the retarder brake as a function of the absolute value of the difference between wheel speed values which are derived from wheel speeds at wheels which can be influenced by the retarder brake and from wheel speeds at wheels which cannot be influenced by the retarder brake. The braking effect is reduced if the absolute value of the difference exceeds a prescribed limit value which is lower than the absolute value of the difference when one of the wheels starts to tend to lock. The effect of the retarder brake can thus already be reduced significantly before the locking point is reached so that the risk of wheels locking which otherwise exists owing to the comparatively slow decrease in braking torque of retarder brakes and thus the associated swerving of the axle of the retarder brake are reliably avoided.
