Abstract:
1. A construction vehicle including at least one traction device, an engine, an engine controller operably coupled to the engine, a drivetrain operably coupled to the at least one traction device and engine for powering the at least one traction device, a transmission controller operably coupled to the drivetrain and configured to obtain a ground speed of the vehicle, a boom implement configured to be raised and lowered to move material, a hydraulic system for providing power to the boom implement, and a power management apparatus including a vehicle control unit in communication with the engine controller, the transmission controller and a power management actuator, wherein the vehicle control unit determines a maximum drivetrain torque for the ground speed obtained by the transmission controller and sends a message to the transmission controller regarding the maximum drivetrain torque, the transmission controller preventing too much power from being delivered to the drivetrain for the ground speed obtained by the transmission controller by reducing engine power to the transmission and increasing engine power to the hydraulic system and the boom implement.
