FAILURE DIAGNOSIS METHOD FOR HALL SENSOR |
| 摘要 |
A failure diagnosis method for a Hall sensor includes: a failure recognizing step of recognizing a failure signal of a Hall sensor by a control unit; a duty increasing step of, when the failure signal is recognized as a result of having performed the failure recognizing step, increasing a driving duty of an oil pump by a preset value; and a failure diagnosing step of diagnosing a failure of the Hall sensor after the duty increasing step. |

1. A failure diagnosis method for a Hall sensor, comprising:
a failure recognizing step of recognizing a failure signal of a Hall sensor by a control unit; a duty increasing step of increasing a driving duty of an oil pump to a preset value, when the failure signal is recognized through the failure recognizing step; and a failure diagnosing step of diagnosing a failure of the Hall sensor after the duty increasing step. |
