Abstract
An offset correction method for an automobile oil pressure sensor determines whether or not an engine start signal is applied. An offset value of the oil pressure sensor installed on an oil pressure line connected to an oil pump is detected within a first preset period after the start signal is applied. An output value of the oil pressure sensor is corrected after the offset value is detected.
Claims6
An offset correction method for an automobile oil pressure sensor, comprising steps of:
- determining whether or not an engine start signal is applied;
- detecting an offset value of the oil pressure sensor installed on an oil pressure line connected to an oil pump within a first preset period after the start signal is applied;
- performing a validity determination by determining whether or not the start signal is applied after a second preset period elapses since turning-off of vehicle ignition;
- and
- correcting an output value of the oil pressure sensor after the offset value is detected.
