Abstract: The present invention discloses a method for energy management, by means of which significant fluctuations in the power consumption in the on-board electrical system are reduced, in particular, current consumption peaks arising due to a very high start-up current of electrical actuators and solenoid valves, are more evenly distributed over time. To achieve this, the method for energy management according to the invention operates predictively, i.e. it determines both the energy available in the subsequent time interval and the energy required on the basis of activation requests, and selects consumers to be activated according to their priority and a prevailing tolerance time within which a consumer must be activated following the submission of its activation request. The tolerance time is thereby continuously adapted.

Abstract: The solution is arrived at with a computer-based diagnostic tester which can exchange information with the control devices installed in the motor vehicle using a diagnostic program via a diagnostic interface and via data lines. The motor vehicle-mounted control devices have program routines for self-diagnostics of the control devices and are capable of storing identified faults in the form of fault codes in reserved memory areas. The diagnostic program which is implemented in the diagnostic tester reads the fault codes out from the reserved memory areas, interprets the fault codes and displays them on a display together with the interpretations. In order to check to what extent repairs which have been performed have been successfully concluded, status polling is carried out using the diagnostic program implemented in the diagnostic tester. During this status polling, the status information of all the fault codes known in the system is interrogated and evaluated.

Abstract: A motor vehicle preventive protection system comprises a plurality of safety devices which are actuated as a function of information from at least one vehicle surroundings detection device. The time remaining prior to a collision is determined when the information from the vehicle surroundings detection device represents an anticipated collision with a collision object. Associated activation times for at least two of the actuators assigned to the safety devices are stored and the time remaining prior to the collision is compared with the activation times. At least one safety device is activated if the time remaining prior to the collision is shorter than or equal to at least one of the activation times of the actuators.

Abstract: The invention concerns a network comprising an interconnecting network and several network nodes that are coupled to said interconnecting network and are designed to adapt their local communication time schedule to the communication time schedule of at least one other network mode, prior to being integrated as active network nodes. A network node to be integrated checks the activity of other network nodes and if no activity is identified, sends out positional messages for other network nodes, said message being fixed by predetermination in its communication time schedule. If a network node cannot be integrated as a reference node, it can only be integrated as an active node if it adapts its local communication time schedule to that of the reference node after receiving positional messages and if a check as to whether its own communication time schedule agrees with the communication time schedules of at least some of the active network nodes proves positive.

Abstract: The invention refers to a method for monitoring a communication media access schedule of a communication controller (5) of a communication system (1) by means of a bus guardian (6). The communication system (1) comprises a communication media (2) and nodes (3) connected to the communication media (2). Each node (3) comprises a communication controller (5) and a bus guardian (6) assigned to the communication controller (5). Messages are transmitted among the nodes (3) across the communication media (2) based on a cyclic time triggered communication media access scheme.
