摘要： For diagnosing a proper functioning of an auxiliary heater in an air mass sensor in an engine system including an internal combustion engine, the auxiliary heater being used for preventing contamination of a sensor area, the air mass sensor communicating air mass information via a signal line during a sensor operating mode and, if a specified state on the signal line is detected, activating the auxiliary heater, the following are performed: setting the state of the signal line to the specified state for a predefined time period in an auxiliary heater operating mode; transmitting a first temperature information before the activation of the auxiliary heater operating mode and a second temperature information via the signal line after expiration of the predefined time period; and detecting the proper functioning of the auxiliary heater depending on the difference between the first temperature information and the second temperature information.

摘要： A method is provided for identifying an averaged sensor value of a state variable of an air system for an internal combustion engine in a motor vehicle, comprising the following steps: acquiring and temporarily storing sensor values at a predefined sampling interval during a segment duration of the state variable, the segment duration corresponding to one period of a pulsation of the state variable; determining an average of the sensor values acquired within the segment duration; correcting the average of the sensor values that has been determined, using a correction variable that depends on the time difference between the segment duration and a multiple of the sampling interval.
摘要翻译：提供了一种用于识别机动车辆中的内燃机的空气系统的状态变量的平均传感器值的方法，包括以下步骤：在预定义的采样间隔期间获取并暂时存储传感器值，状态变量，段持续时间对应于状态变量的脉动的一个周期; 确定在段持续时间内获取的传感器值的平均值; 使用取决于段持续时间和采样间隔的倍数之间的时间差的校正变量来校正已经确定的传感器值的平均值。
