Road Surface
Clearly the condition of the roadway and weather conditions are significant influences regarding wheel slip and the retention of Lateral Locating Forces.
As road surfaces vary and weather conditions impact the tire's ability to maintain good rolling contact, the function of the ABS remains unchanged. Only the stopping distances increase due to the regulated transmission of braking force.
Whatever the road surface or weather, the wheel slip will still be limited to 20-25%.
Regardless of the AST system, good judgement and common sense are still required.
