Park brake system and method for corroborated pressure reporting

A park brake system and method for corroborated pressure reporting are provided. In one example implementation, primary and redundant park brake controllers read their respecting pressure sensors along an air channel to a parking brake. The controllers exchange the sensor readings, and each controller determines whether or not the sensor readings are in agreement. The controllers provide their determinations to an automated driving system. If the sensor readings are not in agreement, the automated driving system can partially or completely disengage or take some other action. Other implementations are provided.
