摘要:
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). Additionally, the wheel (10) is temporarily supplied with an acceleration torque (Ma) by means of an accelerating device of the vehicle during the reduction of the travel speed (v), said acceleration torque acting in the rotating direction (14).

Systems and methods are provided for operating a network arrangement including multiple network devices that are coupled to each other in a ring structure. Each network device includes a control device and a switch device with at least two ports for coupling to a communication path. During operation, at least two VLANs are simultaneously provided in the ring structure, and the sending of a data packet from the control device of a selected network device is performed via a port of the switch device in one of the two VLANs. In order to achieve this, the other port of the switch device of the selected network device is deactivated for the one VLAN. By using two VLANs, a redundant and reliable data transmission may be achieved. A destabilization of the VLANs in the network ring is prevented by the targeted deactivation of specific ports of the sending network device.

The invention relates to a method for operating a communication network (101), in particular an Ethernet network. Network devices (1) which are coupled to the network comprise a switch device (4), a first and a second control device (2, 3) which are coupled to the switch device (4), and the switch device (4) comprises for the first and the second control device (2, 3) a respective input port (10, 14) and emitter port (9, 13) for sending and receiving data via the communication network (6). Ring-shaped communication paths for data are provided so that redundant data can be transmitted in different directions and checked for consistency. An improved protection against failure and error analysis in the event of transmission errors are ensured by the ring-shaped structure using bidirectional communication paths. The invention further relates to a network arrangement (101) comprising several corresponding network devices (100, 200, 300) which operate according to the method.
