Abstract
A slip control system for an off-road vehicle includes a control system configured to output a signal indicative of a first action if a magnitude of slippage of the off-road vehicle relative to a soil surface is greater than a first threshold value and less than or equal to a second threshold value. Furthermore, the control system is configured to output a signal indicative of a second action, different than the first action, if the magnitude of slippage is greater than the second threshold value.
Claims14
A slip control system for an off-road vehicle, comprising:
- at least one controller having a memory and a processor, wherein the at least one controller is configured to:
- receive a first signal indicative of a magnitude of slippage of the off-road vehicle relative to a soil surface;
- receive a second signal indicative of a rate of change of slippage of the off-road vehicle relative to the soil surface;
- perform a first action in response to the magnitude of slippage being greater than a first threshold value and less than or equal to a second threshold value for more than a first threshold duration, wherein the first action comprises alerting an operator;
- perform a second action, different than the first action, in response to the magnitude of slippage being greater than the second threshold value, wherein the second action comprises controlling operation of the off-road vehicle, an implement towed by the off-road vehicle, or a combination thereof;
- perform the first action in response to the rate of change of slippage being greater than a third threshold value and less than or equal to a fourth threshold value;
- and
- not perform the first action in response to the magnitude of slippage being greater than the second threshold value;
- wherein the second threshold value is greater than the first threshold value, and the fourth threshold value is greater than the third threshold value.
