Abstract
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.
Claims23
A method of monitoring for vehicle travel over rumble strips, the method comprising:
- receiving roadway feedback data from a first vehicle sensor for a period of time from a first vehicle system;
- receiving roadway feedback data from a second vehicle sensor for the period of time from a second vehicle system, wherein the first vehicle system is different than the second vehicle system and the second vehicle sensor measures a different physical input to the vehicle than is measured by the first vehicle sensor;
- applying 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;
- identifying travel of a wheel of the vehicle over rumble strips based on the frequency-based analysis;
- and
- autonomously commanding operation of a vehicle system as a corrective action in response to the identified operation of the wheel of the vehicle traveling over the rumble strips.
