Abstract: The present invention provides a method and a device for controlling operational sequences, in particular in a vehicle. In this context, a functional unit for forwarding and receiving data via at least one connecting unit is in contact with at least one bus system. Functional unit is monitored by a monitoring unit. The monitoring unit prevents the forwarding of data by the functional unit via the at least one bus system if the monitoring unit detects an error of the functional unit. In an error case, in order to prevent the forwarding of data by functional unit in a manner as simple as possible, yet one that is safe and reliable, an error signal is emitted by the monitoring unit, which error signal assumes different values as a function of whether an error of the functional unit has been recognized or not, and the error signal is applied to the at least one connecting unit such that the at least one connecting unit is deactivated by the error signal if an error of the functional unit has been detected.

Abstract: The present invention relates to a method and a device for controlling operational sequences, in particular in a vehicle. In this context, a functional unit (3) for forwarding and receiving data via at least one connecting unit (4) is in contact with at least one bus system (2). Functional unit (3) is monitored by a monitoring unit (8). The monitoring unit (8) prevents the forwarding of data by the functional unit (3) via the at least one bus system (2) if it detects an error of the functional unit (3).

Abstract: A method and an arrangement for monitoring the measured-value detection for an electronic power control of a motor of a vehicle is suggested wherein the single computing element outputs a signal which operates on at least one of its input channels or operates indirectly on this at least one input channel by changing the supply voltage. A fault condition is detected when the variable, which is supply via this input channel, exceeds at least one pregiven limit value correlated in time to the output of the control signal.

Abstract: A circuit arrangement for executing a reset, in which controlled resetting of a functional computer and a safety module takes place. A reset stage is able to coerce both the functional computer and the safety module into a reset state, while all output stages are switched off for all reset states. The functional computer and the safety module are connected by a serial interface to continually monitor each other and can mutually reset one another in the case of a fault.

Abstract: The invention is directed to a method and an arrangement for checking the operability of the measured value detection system for an electronic power control arrangement of a motor vehicle. In the invention, and to check operation, the measured variable is converted by an analog/digital converter of the computer and is compared to a signal level determined from a signal derived from this measured variable. A fault condition in the area of the measured value detection system is assumed when impermissible deviations are determined between the two signals.

Abstract: The invention is directed to a method and an arrangement for controlling a power adjusting device in motor vehicles. The adjustment of an electrically actuable power adjusting element is made in pregiven operating states. The power adjusting element is adjusted in accordance with a first value in the region of the full-load position of the power adjusting element, however, not at the full load position itself and is adjusted to a second value in the region of the completely closed position but not at the completely closed position itself.

Abstract: An arrangement for detecting a changing variable in a motor vehicle includes at least one transducer having terminals with at least one terminal being connected to a pole of a supply voltage. In addition, an actuable switch element is provided which interrupts at least one connecting line connected to a terminal. The potential of this terminal is detected relative to a reference potential when the switch element is open and a fault state of the transducer is assumed when there is an impermissible fluctuation of the potential value during at least two detecting operations.

Abstract: An apparatus for controlling motor vehicle safety devices has a plurality of sensors, each coupled to a control unit. The control unit in turn activates inertial restraining devices based on the output signals generated by the sensors.

Abstract: A method and an arrangement for electronically controlling an internal combustion engine of a motor vehicle. The detecting unit is connected to a component determining the power of the engine such as a throttle flap or a control rod or an accelerator pedal and generates at least two position signals. The detecting unit is so configured that with a position change of the power-determining component, the two position signal variables change in opposition. A fault detection associated with this kind of measure permits detecting short circuits as well as shunt faults between the potentiometer wipers.
