REDUNDANT LANE MONITORING WITH FREQUENCY-BASED ANALYSIS OF DATA FROM MULTIPLE SENSORS

A system includes a computer having a processor and memory storing instructions executable by the processor. The instructions include instructions to receive roadway feedback data from a first vehicle sensor for a period of time and receive roadway feedback data from a second vehicle sensor for the period of time. The instructions include instructions to apply frequency-based analysis to both the roadway feedback data from the first vehicle sensor and the roadway feedback data from the second vehicle sensor for the period of time and identify travel of a wheel of the vehicle over rumble strips based on the frequency-based analysis.
