Abstract: A vehicle transmission braking mode comprises determining a set of available clutches of the plurality of clutches that are not being utilized for engagement of a particular forward gear of the plurality of forward gears, determining at least one of a modeled temperature, a measured temperature, and a modeled energy of each clutch of the set of available clutches to obtain a set of at least one of clutch temperatures and energies, and based on at least the set of available clutches and the set of at least one of clutch temperatures and energies, selectively operate the transmission in the transmission braking mode by at least partially applying at least one clutch of the set of available clutches to mitigate or prevent powerflow through the transmission and thereby decrease or maintain a speed of the vehicle and/or reduce acceleration of the vehicle.

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.
