摘要:
A method and a control unit for controlling the authorization of charging operations of electrically operated vehicles. A control unit is provided between a main terminal and a plurality of electric coupler sockets, which are connected to the control unit via a power line. A vehicle to be charged is connected to one of the electric coupler sockets, and the total charging current, which is conducted from the main terminal to the electric coupler sockets via the control unit, is measured. Charging-current requests are transmitted to the control unit by each of the vehicles connected to the electric coupler sockets, and the total charging current is compared to the sum of the charging currents reported by the vehicles connected to the charging outlets. The charging outlets are switched off if the total charging current exceeds the sum. The connecting of a vehicle to be charged includes transmitting authorization information from the vehicle to the control unit. The authorization information is compared to a list of authorized vehicles by the control unit, in order to check the authorization of the vehicle. The transmitting of charging-current requests and authorization information is provided by modulating an alternating current signal upon the power line, the alternating current signal representing the authorization request or the charging-current request.

In a routing method for messages in a network, at least two adjacent network controllers exchange priority information of stored messages and compare this priority information. Furthermore, in the event that the message memory of one of the two network controllers is full, a lower-priority message in the full memory is replaced with a higher-priority message from the adjacent network controller as a function of the comparison of the priority information. The replacing message is provided for transmission on and/or via the full network controller.

Disclosed is a method for calibrating an annular-shaped body which is made of thermoplastic or at least partially crystalline plastic material, to an annular-shaped body which is produced according to the method, and to an oscillating object which is used in the method. Also disclosed is an oscillating object which is used to stimulate oscillations and which is introduced into an annular-shaped body by means of axial forward motion. Localised warming of the annular-shaped body is performed until the glass transition temperature of the material thereof is exceeded by localised contact of the oscillating object with the annular-shaped body. A desired, economical internal measurement having high precision is produced when the calibration section of the oscillating body is immersed into the annular-shaped body.

The different electrical components and cables arranged in the B flange of an electric motor can be installed only with difficulties and are complicated and time-consuming due to the restricted space conditions in the B flange. In order to improve this, it is proposed to recess the B flange's 3 front side 10 facing away from the electric motor 1 at least in sections with respect to an imaginary surface normal to the longitudinal axis 15 of the electric motor 1 in the direction toward the motor housing 2, and to shape the B flange cover's 9 front face resting against the B flange 3 in a mirror-inverted manner to thereby improve the accessibility to the inside of the B flange 3.

A device for damping pressure pulsations, in electronically regulatable vehicle brake systems for damping the pressure pulsations that are caused by pressure generators in a hydraulic circuit connected to it. The device has a housing which encloses a damping chamber and also has at least one hydraulic connection opening into the damping chamber, and a throttle device. The housing and throttle device are embodied as a compact damping unit that can be preassembled, is economical, and can be anchored in only a few work steps to the hydraulic block of an electronically regulatable vehicle brake system.

Apparatus for regulating an engine parameter, in particular the output power or the speed of rotation of an internal combustion engine, wherein there are provided two or more adjustable devices by way of which the engine parameter to be regulated can be influenced. There are provided two or more separate regulators, each of which regulates a respective one of the adjustable devices in dependence on the detected actual value of the engine parameter and a predeterminable reference value. There is also provided a change-over switching device by way of which selectively one of the regulators can be activated for regulating the adjustable device associated therewith.
