Description / Abstract: Purpose.

Provide a common global development and validation performance evaluation of a driveline system that utilizes traction enhancing driveline hardware, e.g., Active On Demand (AOD) All Wheel Drive (AWD) and Limited Slip Differential (LSD) with electronic controls. This procedure is also performed to evaluate the performance of driveline components after being subjected to severe loads resulting from multiple vehicle launches on ʺsplit muʺ surfaces, i.e., left (or right) side of the vehicle on a small frictional coefficient (μ) surface, i.e., ʺlow muʺ surface, and the other side on a large frictional coefficient surface, i.e., ʺhi muʺ surface.

Applicability. Passenger cars and light trucks equipped with driveline traction enhancing hardware beyond normal brake system traction control systems.
