Rough road detection system |
摘要 |
A rough road detection system includes an engine speed module, a feature space module, a normalization module, and a rough road module. The engine speed module generates an engine speed signal based on a crank signal. The feature space module generates a feature space signal based on the engine speed signal. The normalization module generates a normalized signal. The normalized signal is based on the feature space signal and a normalization value that varies in accordance with the engine speed signal. The rough road module determines whether a rough road condition exists based on the normalized signal.
