Abstract
To provide a vehicular charging and generating system capable of issuing alarm to a driver even when failure is caused in a rectifying apparatus of the vehicular charging and generating system, failure detecting means issues alarm when a difference between an output voltage of generated voltage detecting means and an output voltage of average phase voltage detecting means is higher than first difference voltage set when failure is not caused in a rectifying element or when the difference is lower than second difference voltage set when failure is not caused in the rectifying element.
Claims5

- failure detecting means for detecting a failure of a rectifying element constituting the rectifier;
- wherein the failure detecting means detects the failure of the rectifying element by comparing a generated voltage of the vehicular charging generator and an average voltage of a phase voltage of the armature coil.
