A vehicle control system determines an upper non-zero limit on deceleration of a vehicle to prevent rollback of the vehicle down a grade being traveled up on by the vehicle. The upper non-zero limit on deceleration is determined by the controller based on a payload carried by the vehicle, a speed of the vehicle, and a grade of a route being traveled upon by the vehicle. The controller is configured to monitor the deceleration of the vehicle, and to automatically prevent the deceleration of the vehicle from exceeding the upper non-zero limit by controlling one or more of a brake or a motor of the vehicle. The controller also is configured to one or more of actuate the brake or supply current to the motor of the vehicle to prevent rollback of the vehicle while the vehicle is moving up the grade at a non-zero speed.

A drive system includes an engine, an alternator coupled to the engine, the alternator being configured to power at least one auxiliary load, a traction motor system operatively coupled to drive wheels of the vehicle, the traction motor system being configured for receiving primary electrical power from the alternator and for propelling the vehicle in response to the primary electrical power, and a motor electrically connected to the traction motor system and mechanically coupled to the engine. The motor is configured to receive electrical power from the traction motor system in a dynamic braking mode of operation of the traction motor system and to communicate power to the engine during the dynamic braking mode.

A system (for controlling cooling of an alternator) comprises a control system, an alternator, and a blower fan, the alternator having a stator and a rotor. The control system is adapted to estimate one or more temperatures of the stator and/or rotor of the alternator using a thermal model. The control system is also adapted to control the blower fan to cool the alternator by providing a specified amount of air flow across the stator and rotor of the alternator, based on the estimated one or more temperatures of the stator and/or rotor.
