Systems and methods for controlling energy efficiency of electric drive systems

A system for controlling vehicle energy efficiency, comprising:

• an advanced driver assistance system (ADAS), comprising one or more imaging sensors, configured to image an environment of a vehicle;
• a navigation sensor configured to collect navigation data pertaining to the vehicle;
• and
• an electric drive cooling system, comprising:
• a powertrain controller, comprising a processor and a memory;
• one or more electric motors (EMs);
• one or more power electronics (PEs);
• and
• a temperature control system configured to adjust a temperature of the one or more EMs and the one or more PEs,
• wherein the memory is configured to store instructions that, when executed by the processor, cause the processor to:
• determine a route of the vehicle;
• dissect the route of the vehicle into a plurality of segments;
• calculate a travel time for each segment of the plurality of segments;
• divide the travel time into a number of prediction steps, the prediction steps forming a prediction horizon;
• establish one or more road conditions across the prediction horizon, based on the navigation data;
• estimate EM motor speed and torque across the prediction horizon, based on the one or more road conditions;
• estimate a temperature profile for the one or more EMs and the one or more PEs across the prediction horizon, based on the estimated EM motor speed and torque;
• and
• determine one or more control inputs to the temperature control system to cause the one or more EMs and the one or more PEs to function within a desired temperature range;
• wherein the n navigation comprises future road gradient and speed limit data for the vehicle;
• and
• wherein the one or more road conditions comprise the future road gradient and speed limit data.
