Abstract: Disclosed is a method for identifying hydraulic defects in electrohydraulic brake systems for motor vehicles including an electronic regulation and control unit, wheel brakes equipped with inlet and outlet valves, and at least one pressure source. Further disclosed is a device for implementing the method of the invention. According to the disclosed method, the individual causing defect is localized after a defect pattern is identified in order to operate the brake system in an operating mode which takes into account the individual causing defect.

Abstract: A method for increasing the maneuverability and driving stability of an automotive vehicle during cornering, the rotational behavior or the wheel slip of the individual vehicle wheels is monitored, and the distribution of the brake force to the curve-outward wheels compared to the brake force conducted to the curve-inward wheels is varied in dependence on the wheel rotational behavior and on the slip of the wheels. When cornering is detected, a total deceleration of the vehicle that corresponds to the driver's request is determined, and a vehicle deceleration that corresponds to the driver's request is achieved by increasing the brake force at the curve-outward wheels and decreasing or maintaining the brake force at the curve-inward wheels.

Abstract: In a method for increasing the maneuverability and driving stability of an automotive vehicle during cornering, the rotational behavior or the wheel slip of the individual vehicle wheels is monitored, and the distribution of the brake force to the curve-outward wheels compared to the brake force conducted to the curve-inward wheels is varied in dependence on the wheel rotational behavior and/or the slip of the wheels. When cornering is detected, a total deceleration of the vehicle that corresponds to the driver's request is determined, and a vehicle deceleration that corresponds to the driver's request is achieved by increasing the brake force (&Dgr;P1) at the curve-outward wheel(s) and decreasing or maintaining the brake force at the curve-inward wheels.

Abstract: A reciprocating machine with a friction bearing crank mechanism having a monitoring device monitoring operating parameters of the friction bearings of the crank mechanism via at least one sensor which is in connection with an evaluation device. At least one sensor is disposed near a part of the crank mechanism which moves in operation relative to the machine's housing. The connection of the sensor with the evaluation device is guided at least in part via the crankshaft. This provides a simple and effective monitoring option for the friction bearings of the crank mechanism and for other machine-specific parameters.

Abstract: The invention consists in the determination of road conditions during unbraked or partially braked ride of a vehicle through a time derivative of characteristics which are detected on at least one wheel of the vehicle and whose averages are created.

Abstract: Disclosed is a method for identifying a critical braking operation of a two-track vehicle during cornering, which features the steps of detecting the running behaviour of a left-hand side wheel and of a right-hand side wheel, of comparing the running behaviour and/or of evaluating the time variation of at least one left-hand side wheel or right-hand side wheel, and of identifying a critical braking operation on the basis of the result of the comparison and/or of the result of the evaluation. As a reaction, there may ensue the reduction of the braking pressure of a wheel on the inside of the corner in response to identification.

Abstract: A circuit configuration for an anti-lock brake system, which receives input from wheel sensors positioned on the driven wheels, comprises a monitoring circuit (7) which triggers a test cycle (duration T.sub.Test) when the two wheels of a driven axle signal instability for more than a predefined time span (T) during a control cycle. By way of the test cycle, braking pressure is introduced into the wheel brake of the instantaneously slower wheel (v.sub.1, v.sub.min -wheel) of the driven axle and the reaction of the driven wheels to the braking pressure delivered is assessed.

Abstract: In an air-cooled internal combustion engine with one or more cylinder banks, a cooling-air blower and an intercooler for the air charge, the intercooler--as seen in the flow direction of the cooling-air--is placed directly in front of the cylinder bank, i.e. preferably over its entire length. The intercooler is subject to the full stream of cooling-air passing through the cylinder bank. A comparison of conventional designs and the arrangement described by the invention shows that the power requirements of the blower are reduced by as much as 15% in conventional assemblies, and by even 20% in special-purpose vehicles as described below.

Abstract: In order to achieve less deformation under gas pressure load and also under thermal load, the bottom piece of a piston with ring-carrying barrel is configured as a supporting cone tapering towards the piston pin and connected with the piston pin bosses by means of supporting elements. Cone, bosses and supporting elements are made in one piece. The supporting elements comprise walls extending essentially parallel to the axis of the piston pin. First distance (A) to the outer perimeter of the piston in the direction of the piston pin axis (Y--Y) are greater than the corresponding second distances (B) normal to this axis. The end parts of the walls are curved inwardly and leave open an area around an axis (X--X) normal to the piston pin axis.
