Abstract
After a vehicle is started up, a voltage value detected by a voltage sensor while a voltage detection target and the voltage sensor are disconnected from each other is obtained as an offset voltage, and the voltage value detected by the voltage sensor is corrected based upon the offset voltage thus obtained.
Claims12
An offset correction apparatus for an automotive voltage sensor, comprising:
- a connection/disconnection device that connects/disconnects a voltage sensor and a voltage detection target to/from each other;
- an offset voltage obtaining device that obtains as an offset voltage a voltage value detected by the voltage sensor while the voltage detection target and the voltage sensor are disconnected from each other by the connection/disconnection device;
- and
- a voltage correction device that corrects the voltage value detected by the voltage sensor based upon the offset voltage obtained by the offset voltage obtaining device.
