Title:
ガスセンサのための駆動制御回路及び駆動制御方法
Document Type and Number:
Japanese Patent JP4746238
Kind Code:
B2
Abstract:
A method and device for driving a gas sensor includes a three-point circuit determining a temperature of a gas sensor having a resistive heating element by determining a measuring current with a measuring resistor flowing through the resistor in a measuring phase. The three-point measurement makes it possible to determine accurately the line resistance of an incoming line branch, which can also be used approximately for the line resistance of another incoming line branch. Naturally, the tap may also be provided on the incoming line side.
