    • A method for monitoring a pressure sensor, which determines a pressure in a pressure accumulator regulated by a pressure actuator, includes the steps of calculating an expected pressure value in the pressure accumulator for a given point in time based on a holding pressure preset by the pressure actuator and based on a detected rate of change in a mass balance of a medium contained in the pressure accumulator. A pressure value in the pressure accumulator is determined with the pressure sensor at the given point in time. The expected pressure value is compared with the determined pressure value and a malfunction in the pressure sensor is detected if the pressure values deviate from each other beyond a predetermined value. A device for monitoring a pressure sensor is also provided.
    • 一种用于监测压力传感器的方法,其确定由压力致动器调节的压力存储器中的压力,包括以下步骤:基于由压力预设的保持压力,计算给定时间点内的蓄压器中的预期压力值 并且基于检测到的包含在蓄压器中的介质的质量平衡的变化率。 在给定的时间点,用压力传感器确定蓄能器中的压力值。 将预期压力值与确定的压力值进行比较,并且如果压力值彼此偏离预定值,则检测压力传感器中的故障。 还提供了用于监测压力传感器的装置。

    • A control apparatus for an internal combustion engine has an exhaust-gas turbocharger regulator which, as a function of a setpoint boost pressure and an actual boost pressure, determines a controlled actuating-variable exhaust-gas back-pressure. An exhaust-gas recirculation regulator determines, as a function of a setpoint air mass flow and an actual air mass flow, a controlled actuating-variable exhaust-gas recirculation mass flow. A first decoupling unit determines a decoupling mass flow in an exhaust-gas section. A second decoupling unit determines a decoupling exhaust-gas back-pressure. A first conversion unit determines a signal for the exhaust-gas turbocharger actuator as a function of the pilot-control actuating-variable exhaust-gas back-pressure, the controlled actuating-variable exhaust-gas back-pressure and the decoupling mass flow. A second conversion unit determines a signal for the exhaust-gas recirculation valve as a function of the pilot-control actuating-variable exhaust-gas recirculation mass flow, the controlled actuating-variable exhaust-gas recirculation mass flow and the decoupling exhaust-gas back-pressure.
