AI Technical Summary

Technical Problem

In existing technologies, sensors are prone to false triggering due to malfunctions during normal driving, especially on uneven roads or under severe driving conditions, making it difficult to effectively identify and avoid false triggering caused by sensor malfunctions.

Method used

By combining explicit and implicit monitoring methods, sensor faults are identified by comparing the signal characteristics of multiple sensors with identification thresholds, including using different thresholds under normal and abnormal driving conditions, thus ensuring the robustness and availability of sensor monitoring.

Benefits of technology

It improves the diagnostic coverage and availability of sensor monitoring, reduces the risk of false triggers, and is particularly effective in identifying sensor malfunctions under complex driving conditions.

Abstract

Embodiments of the present disclosure relate to a method for monitoring a sensor in a vehicle. The invention relates to a method for monitoring a sensor (20) which detects a quantity and outputs at least one corresponding signal (30), wherein the at least one corresponding signal (30) is pre-processed such that at least one signal feature (40) is obtained, the at least one signal feature (40) is compared with at least one identification threshold (42), wherein the at least one identification threshold (42) is obtained by analyzing a signal (32) of a further sensor (22), and the method is executed in order to detect a sensor failure.
