Abstract

A computer system (100) for controlling a power usage of a traction electric machine (104) of a vehicle (202), the computer system comprising processing circuitry (102) configured to: predict a power profile (127) for an upcoming route section (204, 220); determine a thermal buffer (116) of a component or subsystem (118) of the vehicle (202) that is available before a thermal limit (115) is reached, the component or subsystem is associated with a usage restriction due to increased power usage of a driveline (119) of the vehicle, determine a constant power level (124) of the traction electric machine for the upcoming route section based on the thermal buffer and the predicted power profile for the upcoming route section that allows an increase in temperature of the component or subsystem without exceeding the thermal limit while travelling through the upcoming route section, and provide an output message (C) indicating the constant power level.
