  • Patent number: 10101294
    Abstract: Provided is a method for recovering output of a gas sensor in shorter time. The method includes: determining a recovering temperature T1 and a recovering time ??1 based on a condition setting range where a high recovery rate is expected; and recovering the output based on T1 and ??1, wherein in the recovering, a duty ratio for a heater is instantly increased to value D1 higher than a value in a normal driving mode when the recovering starts, D1 is maintained up to T1, and PID control is performed by reducing the duty ratio to value D2 to maintain T1. After an elapse of ??1, the duty ratio is reduced to value D3. When the temperature of the element reaches a value 1 to 1.2 times as high as the temperature in the normal drive mode, the duty ratio is instantly changed to value D0 in the normal drive mode.
