摘要： PROBLEM TO BE SOLVED: To determine whether abnormal conditions occur in a NOx sensor. SOLUTION: When the output value of the NOx sensor for measuring NOx concentration in an exhaust gas is less than a predetermined threshold (S7), if a NOx integrated quantity estimated from an engine state is greater than a first predetermined value (S8), a vehicle travel distance is greater than a second predetermined value (S9), or fuel consumption is greater than a third predetermined value (S10), it is determined that the abnormal conditions occur in the NOx sensor and thus an alarm unit is operated (S11). Namely, if the NOx sensor is normal, it is very rarely that the output value continuously becomes less than the predetermined threshold in a prescribed period. Meanwhile, if the abnormal conditions occur in the NOx sensor, the output value continuously becomes less than the predetermined threshold in a prescribed period. By using the characteristics, it is determined whether the abnormal conditions occur in the NOx sensor. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：确定NOx传感器中是否发生异常情况。解决方案：当用于测量废气中的NOx浓度的NOx传感器的输出值小于预定阈值（S7）时，如果从发动机状态估计的NOx积分量大于第一预定值（S8 ），车辆行驶距离大于第二规定值（S9）或燃料消耗量大于第三规定值（S10）时，判定为在NOx传感器中发生异常状态，从而使报警单元动作（S11）。即，如果NOx传感器正常，则输出值在规定期间内连续变得小于规定的阈值很少。同时，如果在NOx传感器中发生异常情况，则输出值在规定期间连续变得小于规定的阈值。通过使用这些特性，确定NOx传感器中是否发生异常状况。版权所有（C）2010，JPO＆INPIT
