Abstract
A system and method for limiting a turning speed of a compactor is disclosed. The compactor includes a steering member configured to receive operator steering input. The system may comprise a speed sensor, and a controller in communication with the speed sensor. The speed sensor may be mounted on the compactor and configured to measure a travel speed of the compactor over a surface. In some embodiments, a temperature sensor, configured to measure a temperature of the surface, may be mounted on the compactor and in communication with the controller. The controller is configured to receive the travel speed and/or temperature, and to limit a turning speed of the compactor when a condition is satisfied.

A system on a compactor, the compactor including a steering member, the steering member configured to receive operator steering input, the system comprising:
- a speed sensor mounted on the compactor, the speed sensor configured to measure a travel speed of the compactor over a surface;
- and
- a controller in communication with the speed sensor, the controller configured to:
- receive the travel speed of the compactor from the speed sensor;
- and
- limit a turning speed of the compactor when a condition is satisfied,
- wherein the condition is satisfied when the travel speed is less than a speed threshold.
A method of limiting a turning speed of a compactor including a steering member, a controller, a speed sensor, and a temperature sensor, the steering member configured to receive operator steering input, the speed sensor mounted on the compactor and in communication with the controller, the speed sensor configured to measure a travel speed of the compactor over a surface, the temperature sensor mounted on the compactor, the temperature sensor in communication with the controller and configured to measure a temperature of the surface, the method comprising:
- receiving, by the controller, the travel speed;
- and
- limiting the turning speed of the compactor when a condition is satisfied,
- wherein the condition is satisfied when the travel speed is less than a speed threshold.
A system on a compactor, the compactor including a steering member, the steering member configured to receive operator steering input, the system comprising:
- a speed sensor mounted on the compactor, the speed sensor configured to measure a travel speed of the compactor over a surface;
- a temperature sensor mounted on the compactor, the temperature sensor configured to measure a temperature of the surface;
- a steering speed sensor mounted on the compactor, the steering speed sensor configured to measure a steering speed of the steering member;
- and
- a controller in communication with the speed sensor, the temperature sensor and the steering speed sensor, the controller configured to:
- receive the travel speed from the speed sensor and the temperature from the temperature sensor;
- alert an operator each time the travel speed is less than a speed threshold or the temperature is greater than a temperature threshold;
- receive the steering speed from the steering speed sensor;
- and
- log each incident where the steering speed is greater than a turning threshold for a time period after the alert.
