Abstract
A computer system and computer-implemented method for determining a longitudinal slip limit for a steered axle of a vehicle having two steered axles are disclosed. The computer system has processing circuitry to acquire a reference body slip for a steered axle of the vehicle; acquire a current body slip for the steered axle; determine a first difference between the reference body slip and the current body slip; acquire an initial longitudinal slip limit for the steered axle; and determine an adjusted longitudinal slip limit for the steered axle based on the first difference and the initial longitudinal slip limit for the steered axle.

A computer system for determining a longitudinal slip limit for a steered axle of a vehicle having two steered axles, the computer system comprising processing circuitry configured to:
- acquire a reference body slip for a steered axle of the vehicle;
- acquire a current body slip for the steered axle;
- determine a first difference between the reference body slip and the current body slip;
- acquire an initial longitudinal slip limit for the steered axle;
- and
- determine an adjusted longitudinal slip limit for the steered axle based on the first difference and the initial longitudinal slip limit for the steered axle.
A computer-implemented method for determining a longitudinal slip limit for a steered axle of a vehicle having two steered axles, the computer-implemented method comprising:
- acquiring, by processing circuitry of a computer system, a reference body slip for a steered axle of the vehicle;
- acquiring, by the processing circuitry, a current body slip for the steered axle;
- determining, by the processing circuitry, a first difference between the reference body slip and the current body slip;
- acquiring, by the processing circuitry, an initial longitudinal slip limit for the steered axle;
- and
- determining, by the processing circuitry, an adjusted longitudinal slip limit for the steered axle based on the first difference and the initial longitudinal slip limit for the steered axle.
