Abstract: Integrated circuit (1) with a system base chip that has base elements for a transceiver system for a motor vehicle data bus, i.e. system power supply (3) and circuit block (2) for system resetting and monitoring. The circuit also comprises an interface circuit (4, 5) that autonomously processes a data bus protocol, e.g. local interconnect network (LIN) protocol. Data bus protocol processing includes bit rate detection and a serial-parallel converter (2) that uses the bit rate detected by the interface circuit.

Abstract: A circuit arrangement for vehicles for generating at least two DC output voltages (V A1 , V A2 ) from at least one DC input voltage (V E ), wherein the DC output voltages (V A1 , V A2 ) are smaller than the DC input voltage (V E ), the circuit arrangement comprising voltage regulating means ( 3, 4; 13, 14 ) for generating the DC output voltages (V A1 , V A2 ), and wherein the DC input voltage (V E ) is applied to a DC/DC converter ( 2; 12 ) which can be switched on or off by a control means ( 5; 15 ) and supplies a lower voltage than the DC input voltage (V E ) to the voltage regulating means.

Abstract: Each subscriber may pass a signal to a CAN (Controller Area Network) data bus, changing the signal level from a rest value (50) to an active signal level (42-48). Each subscriber passes a signal in turn. There are blank time periods (Delta td) between the first signals during a partial net drive period (T). There is an end period (Delta t) which is greater than a critical time period (Delta tk) before the start of the full net drive period (G). The last signals from the subscribers are transmitted during the full net drive period.

Abstract: The application-executing device is provided with a protocol controller unit (42) which is supplied with voltage in the event of there being an incoming message on the data-bus (10). The protocol controller unit is preferably activated by the incoming message, which is compared with a reference message associated with the application, and stored in the protocol controller unit. Independent claims are included for a transceiver unit, a system chip unit, and the use of the method or chip unit to activate a device in a motor vehicle.

Abstract: Method for monitoring the operation of a system (100) microcontroller (300) in which a monitoring module (10), assigned to the microcontroller unit, generates an acknowledgement signal when the microcontroller is successfully reset. An Independent claim is made for a system chip unit (200) for monitoring the operation of a microcontroller unit with a monitoring module for monitoring the a reset unit (40) that is connected to the microcontroller. The invention also relates to a corresponding system, especially a control system.

Abstract: The method switches the system from a partial network operation to a full network operation. In the partial operation at least one node and/or subscriber of the system is in a low current consumption state and is not communicated with or activated by the system data signal level. In the full operation all nodes or subscribers are communicated with and/or activated by the signal level of the data on the system. The system is switched to full network operation in which at least one definite, continual and/or symmetrical signal level pattern can be recognized in the data on the system. Independent claims also cover a system for carrying out the method.

Abstract: To enable a method and a base chip (200) for monitoring, by means of at least one base chip (200), the operation of at least one microcontroller unit (300) that is intended for at least one application and is associated with a system (100) to be further developed in such a way a reset of the microcontroller unit (300) only takes place under defined conditions, it is proposed that a reset (R) of the microcontroller unit (300) is caused if at least one special sequence, and particularly at least one drive or access sequence assigned to the reset operation (R), is applied to the base chip (200).

Abstract: A method for measuring the difference in earth potential of components of a networked system, especially for testing the earth contacts between networked control units linked via a bus system. The method has the following steps: measurement of the voltage level on transmitting and receiving lines in an idle state and comparison with a threshold value; generation of an error signal if the threshold is exceeded; and testing over a longer time period. An Independent claim is made for a circuit arrangement for testing the earthing of components of a networked system.
