1. A vehicle management system, comprising:
a measuring device that measures a transferred displacement between a drive unit and a wheel coupled to the drive unit; and
a torque control configured to:
obtain, from the measuring device, lash angle information corresponding to the transferred displacement between the drive unit and the wheel, and output, based on the lash angle information, torque shaping logic to the drive unit,
wherein the measuring device is configured to measure the transferred displacement between the drive unit and the wheel when a vehicle is in a locked state and greater than a threshold amount of time has passed since the vehicle transitioned into the locked state and prior to the vehicle transitioning into a sleep state.
