Methods and systems are provided for a drivetrain system comprising: a first prime mover for supplying a torque to a front axle; a second prime mover for supplying a torque to a rear axle; and a controller configured to, in response to a torque reversal, command the front axle and the rear axle to cross lash zones sequentially.

Systems and methods are provided for a camless reciprocating engine control system that uses laser absorption spectroscopy (LAS) sensors and artificial intelligence/machine learning to optimize engine operation. The control system evaluates LAS data in real time or substantially real time to optimize the operation of the engine through dynamic management of camless engine components such as intake valves, exhaust valves, fuel injectors, spark plugs, and variable compression mechanisms.
