Abstract: In order to achieve a vehicle wheel (10) slip relative to a roadway (12) while braking the vehicle, said slip being as advantageous as possible, the rotational speed (w) of the wheel (10) can be actively reduced by an ABS by means of a braking intervention and passively allowed to accelerate again via the roadway (12) when the brake is released. The slip of the wheel (10) oscillates by an optimal slip value during the ABS regulating process. The aim of the invention is to improve an anti-lock braking system for a vehicle. In the method according to the invention, at least one wheel (10) of the vehicle is supplied with a braking torque (Mb) in order to temporarily reduce a travel speed (v) of the vehicle relative to a rolling surface (12), said braking torque acting against a rotating direction (14) of the wheel (10).

Abstract: A method is provided for computer-supported development of an overall system including subsystems. The subsystems include real products and virtual behavior models simulated in real-time, used in phases of the right branch of the V-model, including development steps “MIL,” “SIL” and “VPIL.” Each development step includes an environment model, a reusable multiphysics model and software. The development step “HIL” also includes another physics unit simulating parts of the hardware of a product that are only virtually present. The method provides a temporally parallel and spatially divided integration, and a corresponding test, of components on various levels (e.g., the right-hand branch of a V-model performed by the system developer). Open-loop and closed-loop control functions or processes for the overall system level may already be developed, even though all of the subsystems are not yet present. No parallel systems are required where new processes are run in advance.

Pressure generated in chamber may be controlled by moving a heating element. Additional pressure during cooling-down is exerted on the butt joint by moving one clamping in the direction of the butt joint. A thin foil of a fluorine-containing thermoplastic inserted between the abutting surfaces facilitates joining of the surfaces.
