1. Method for monitoring a sensing system for a host vehicle equipped with wireless inter-vehicle communications capability, comprising:
- said host vehicle determining a respective measure of an ambient environmental condition utilizing a sensor equipped on said host vehicle;
receiving wireless transmissions from other vehicles within communication range comprising corresponding respective measures of said ambient environmental condition;
diagnosing integrity of the host vehicle respective measure of the ambient environmental condition based on the host vehicle respective measure of the ambient environmental condition and the other vehicles respective measures of said ambient environmental condition;
detecting an in-range fault of the sensor based upon the host vehicle respective measure of the ambient environmental condition and the other vehicles respective measures of said ambient environmental condition; and
estimating a correct ambient environmental condition for the host vehicle associated with only the other vehicles respective measures of said ambient environmental condition when an in-range fault is detected.
