US 12,360,011 B2 · System and method for automatic detection of dual wheels

Abstract

A distance sensor is used for automatically detecting whether an outer wheel of a dual-wheel axle is present. The distance sensor is mounted to detect a distance between the sensor and an outer wheel of a dual-wheel axle. A controller compares the distance information with an expected range of distances if the outer wheel is present and determines that the wheel is not present if the measured distance falls outside the expected range. The methods and systems are particularly suitable for mobile machines, such as a combine harvester, having a rollover risk reduction system and/or a stability control system reliant on accurate width data for the machine, and which can be configured to apply different limits for maximum steering angle and/or maximum speed depending on whether the outer wheel is found to be present.

Dependent claims

A method of detecting a presence of dual wheels on a dual-wheel axle of a mobile machine, the method comprising:

using a distance sensor mounted to the mobile machine to determine whether an outer wheel of the dual-wheel axle is present;
using presence or absence of the outer wheel to assess a rollover risk of the mobile machine;
and
adopting at least one of a maximum steering angle and a maximum ground speed for the mobile machine based at least in part on the presence or absence of the outer wheel of the dual-wheel axle.

1 more element

A system for detecting a presence of dual wheels on a dual-wheel axle of a mobile machine, the system comprising:

a distance sensor mounted to the mobile machine having a dual-wheel axle, the distance sensor configured to detect distance information relating to a distance between a known datum and a part of an outer wheel of the dual-wheel axle when the outer wheel is present on the dual-wheel axle;
and
at least one controller configured to receive distance information from the distance sensor and to determine whether the outer wheel is present on the dual-wheel axle based at least in part on the distance information, use presence or absence of the outer wheel to assess a rollover risk of the mobile machine, and adopt at least one of a maximum steering angle and a maximum ground speed for the mobile machine based at least in part on the presence or absence of the outer wheel of the dual-wheel axle.
