Method to estimate the output current of an automotive generator (alternator) |
摘要 |
A control system of a vehicle comprises a current estimation module, a current sensor, and a current diagnostic module. The current estimation module determines an estimated output current of a generator of the vehicle based on an engine speed when the generator is operating in a steady-state condition. The current sensor measures an output current of the generator. The current diagnostic module diagnoses a condition of the current sensor based on the estimated output current and the measured output current. |
