Abstract
A method for controlling a vehicle system includes determining a vehicle reference speed using an off-board-based input speed and an onboard-based input speed. The off-board-based input speed is representative of a moving speed of the vehicle system and is determined from data received from an off-board device. The onboard-based input speed is representative of the moving speed of the vehicle system and is determined from data obtained from an onboard device. The method includes using the vehicle reference speed to at least one of measure wheel creep for one or more wheels of the vehicle system or control at least one of torques applied by or rotational speeds of one or more motors of the vehicle system.
