Document Type and Number:
Japanese Patent JP2741381
Kind Code:
B2
Abstract:
When the output of a gas sensor is approximately constant, the sensor output is stored as a reference output.

The sensor output which is constant is detected by establishing that the difference between a maximum and a minimum of sensor output in a predetermined section is not greater than a specified value.
