A sensor arrangement for a braking system of a vehicle is disclosed comprising a connection interface, a control unit, and a sensor. The sensor has an external interface with electrical contacts via which the sensor is connected to the control unit. The control unit is connected to and supplied with power via the connection interface and exchanges data with a higher-level unit via the connection interface. The sensor is provided power via the electrical contact points and provides electrical output signals via the electrical contact points. A first contact point provides a first electrical output signal and is connected to the connection interface via a first switching element such that the first contact point is connected to the connection interface when the first switching element is in the deenergized state and is disconnected from the connection interface when the first switching element is in the energized state.

Sensor arrangement for a braking system of a vehicle and corresponding braking system

A drive assembly has a housing block, on which there is arranged an electrical machine. The latter has a working shaft mounted in a shaft bore of the housing block and the rotational position of which is detected by a sensor device formed by a signal transmitter and a signal receiver comprising evaluation electronics. The shaft bore is closed by a cover, which is arranged between signal transmitter and signal receiver. The cover is formed in one piece with an electronics housing of the signal receiver. A centering device for the signal receiver is formed on the housing block on the electronics housing. The disclosed drive assembly simplifies the construction, functional testing and mounting of the signal receiver and at the same time improves the protection thereof against damaging environmental influences.

Drive assembly, in particular hydraulic assembly of an electronically slip-controllable vehicle brake system

A connecting arrangement includes an electronic component and a printed circuit board, and a method includes establishing a solder connection between the component and circuit board. The component has a housing with a support area, and a contact element with a first contact area running parallel to the support area of the housing, a second contact area at a prespecified angle relative to the first contact area, and a rounded transition region formed between the first and second contact areas. The circuit board has a first surface with a soldering area including a constriction, a first section, and a second section connected to the first section via the constriction. The transition region is in a region of the constriction. The second contact area is connected to the second section via a solder connection. The support area is at an angle relative to the first surface corresponding to the prespecified angle.

Connecting arrangement and corresponding method for mounting an electronic component on a printed circuit board

A system () includes an electrical load system () with a load network battery (), and a fuel cell system (). Operation is simplified, especially during start of the fuel cell system () if the fuel cell system () has a system battery (). A system voltage across the system battery () can be supplied to electrical system loads () of the fuel cell system () and, via a load voltage converter () and at least one additional voltage converter (), to the load system () and secondary electrical loads ().

Arrangement comprising a fuel cell system

A fuel cell system () has a fuel cell () and a reformer (). A careful operation of the fuel cell system (), in particular during a start-up of the fuel cell system (), is obtained when the fuel cell system () is equipped with a reformer heating burner (additional burner) (). The heat of reformer heating burner waste gas of the reformer heating burner () is fed to the reformer ().

Fuel cell system

A fuel cell system (), especially in a motor vehicle, is provided with a fuel cell (), which generates electric current during the operation from anode gas and cathode gas, with a residual gas burner (), which reacts anode waste gas with cathode waste gas into burner waste gas during the operation; with an air delivery device (), which feeds air as cathode gas to the fuel cell () via a fuel cell air line () during the operation; and with a first heat exchanger (), which couples a waste gas line () removing burner waste gas from the residual gas burner () with the fuel cell air line () in a heat-transmitting operation. The start-up process of the system () is improved with an auxiliary burner (), which reacts air with a fuel into an auxiliary burner waste gas during the operation; with a bypass air line (), which is connected on the inlet side to the fuel cell air line () between the air delivery device () and the first heat exchanger () and which is connected to the fuel cell air line () on the outlet side between the first heat exchanger () and the fuel cell (). A second heat exchanger () couples an auxiliary waste gas line () removing auxiliary burner waste gas from the auxiliary burner () with the bypass air line () in a heat-transmitting manner.
