Abstract:
A method, and related device, for operating a brake device of a vehicle with brake slip regulation (ABS) on roadways with different friction coefficients on different sides, as a result of which a braking yaw moment is imparted to the vehicle during braking, characterized in that, on at least one axle of the vehicle, an absolute brake pressure difference between the brake pressure at the wheel with the higher friction coefficient and the brake pressure at the wheel with the lower friction coefficient is adapted as a function of a steer input, intended to produce a yaw moment acting counter to the braking yaw moment, by the driver and/or by an automatically intervening auxiliary steering system.

Abstract:
An electronic power circuit includes several power modules (1) and is especially for controlling an electrical machine. Each power module (1) includes a plate-shaped integrated electronic circuit arrangement (2) having several electrical terminals. A perpendicular bent-over electrically conducting side leg (3) is arranged on each of two opposite-lying sides of the plate-shaped circuit arrangement (2). The side leg (3) forms an electrical contact and, in this way, the power module (1) has a U-shaped cross section. Each side leg (3) is provided with connecting elements via which two or several power modules (1) can be electrically and mechanically fixedly connected to each other while forming a mutual spacing between the plate-shaped circuit arrangement (2) via the side legs (3) for forming the electronic power circuit.

Abstract:
A cooling device for an internal combustion engine is provided. During assembly, the radiator and the cooler are connected by first connecting the radiator and the cooler via a lower plug-in connection as a result of a vertical joining motion and then bringing the radiator and the cooler into a slightly tilted position. The position is achieved via limited swiveling mobility of the lower plug-in connection, whereby the required degree of freedom is created so that the required distance of the radiator and of the cooler for attaching the upper first plug-in connection can be set. The upper-first plug-in connection is then attached in a final assembly step via an attachment device that is substantially orthogonal to the plane of the cooler. The limited mobility ensures that thermal or production-related tolerances due to the different operating temperatures of the radiator and the cooler are compensated during operation.
