Abstract
A speed-based system for controlling a pump displacement to control a pump flow rate of a hydraulic pump in a vehicle, such as a hybrid. The system includes a plurality of sensors, a controller, and a hydraulic pump. The controller is configured to receive data from the sensors, ascertain a speed of the vehicle, determine a target pump displacement, and transmit the target pump displacement. The target pump displacement is less than a predetermined maximum value when the speed of the vehicle is greater than a first predefined threshold, and equal to the predetermined maximum value when the speed of the vehicle is less than or equal to the first predefined threshold. The hydraulic pump is configured to ascertain an actual pump displacement, receive the target pump displacement from the controller, and alter the actual pump displacement to the target pump displacement.
