Abstract
A power limiting system, such as an engine output power regulator (32), is combined with a power distributing system, such as a torque proportioning differential (18), to limit excessive wheel slip while utilizing more of available traction. Slip determination and control logic (36) reduces drive power with respect to operator demand in response to a measure of wheel slip above a threshold 'T'. Threshold determining logic (56) adjusts the threshold 'T' from a first target value 'T1' to a higher second target value 'T' from a the drive power is reduced and drive wheels (24 and 26) are rotating at the same speed.
