Abstract
An engine rpm signal processing method in a vehicle, may include a low speed determination step for determining whether an engine rpm sensor signal needs to be subjected to post processing when the engine rpm sensor signal is less than a predetermined first reference speed, and a filtering step for processing the engine rpm sensor signal with a Kalman filter to output a filtered engine rpm when it is determined in the low speed determination step that the post processing of the engine rpm sensor signal is necessary.
Claims6
An engine rpm signal processing method in a vehicle, comprising:
- a low speed determination step for determining whether an engine rpm sensor signal needs to be subjected to post processing when the engine rpm sensor signal is less than a predetermined first reference speed;
- and
- a filtering step for processing the engine rpm sensor signal with a Kalman filter to output a filtered engine rpm when it is determined in the low speed determination step that the post processing of the engine rpm sensor signal is necessary.
