Abstract
A system is provided that includes a detection circuit having a first and second sensor. The first sensor is configured to measure a rotational speed of a first wheel. The second sensor is coupled to a vehicle chassis and configured to measure a position over time of the vehicle chassis. The system further includes a controller circuit configured to determine a shock frequency based on the position of the vehicle chassis. The controller circuit is further configured to determine a condition (e.g., an anomalous condition) of the first wheel based on the shock frequency and the rotational speed, and may be further configured for vehicle control based on the determined condition.
Claims20
A system comprising:
- a speed sensor configured to measure a rotational speed of a wheel of a vehicle;
- a movement sensor configured to measure one or more other characteristics of movement of the vehicle;
- and
- a controller configured to identify a repeated event in the one or more other characteristics of the movement of the vehicle and to determine a frequency associated with the repeated event, the controller configured to determine a state of a route being traveled upon by the vehicle based on the rotational speed of the wheel and the frequency associated with the repeated event.
A method comprising:
- determining a rotational speed of a wheel of a vehicle;
- determining one or more other characteristics of movement of the vehicle;
- and
- identifying a repeated event in the one or more other characteristics of the movement of the vehicle;
- determining a frequency associated with the repeated event;
- and
- determining a state of a route being traveled upon by the vehicle based on the rotational speed of the wheel and the frequency associated with the repeated event.
A method comprising:
- receiving a speed measurement signal from a first sensor and a position measurement signal from a second sensor, the speed measurement signal representing a rotational speed of a wheel of a vehicle, the position measurement signal representing changes in a position of the vehicle;
- identifying a repeated event in the position measurement signal;
- determining a frequency based at least in part on the repeated event;
- and
- determining a state of a route being traveled upon by the vehicle a state of the wheel based on the frequency and the rotational speed.
