Plausibility test for air pressure sensors in vehicles

摘要

The motor vehicle has at least two air pressure sensors (14,16) for detecting lateral collisions and a plausibility device (26) that receives a pressure signal from both air pressure sensors and compares them together to detect a faulty function. At least one air pressure sensor is mounted on a door (10,12) of the vehicle. The signals are transferred via at least one data bus system.
