Abstract

See full text

A vehicle management system includes a torque control generates torque shaping logic for managing torque output of a drive unit and limiting displacement between a drive unit of a vehicle and a wheel coupled to the drive unit. A measuring device monitors a transferred displacement between the drive unit and the wheel coupled to the drive unit when the drive unit is operating to measure a lash angle corresponding to the transferred displacement between the drive unit and the wheel. The measuring device can provide data (e.g., displacement data), indicating the lash angle information, to the vehicle management system. Based on the lash angle information, the torque output generates the torque shaping logic used to manage the torque output of the drive unit.
