Abstract

See full text

A drum drive system includes a controller configured to control a prime mover, a variable displacement pump, and a variable displacement motor of the vehicle to provide a target drum speed for a drum of the vehicle. To provide the target drum speed, the controller having programmed instructions to (i) initially operate the variable displacement motor at a maximum motor displacement and operate the variable displacement pump at a pump displacement that provides the target drum speed without needing to actively manipulate a prime mover speed of the prime mover, (ii) increase the pump displacement and decrease a motor displacement without needing to actively manipulate the prime mover speed while still providing the target drum speed, and (iii) increase the prime mover speed if necessary to maintain the target drum speed in response to the pump displacement reaching a maximum pump displacement and the motor displacement reaching a minimum motor displacement.
