Abstract: Methods and systems are provided for controlling thermal conditioning of a battery system associated with brakes of a vehicle towing a trailer. In one embodiment, a method includes: determining, by a processor, that a temperature of the battery system is outside of a defined temperature range; determining, by the processor, a delta value between a brake request and a battery charge limit; generating, by the processor, a control signal to at least one of a heater and a compressor of the vehicle based on the delta value; generating, by the processor, a control signal to the battery system to initiate regeneration braking; and generating, by the processor, a braking reduction request to reduce braking by the trailer.

Abstract: A cruise control method for a vehicle includes receiving a set speed and determining a commanded axle torque to maintain the set speed on a road that is flat. The method further includes commanding a propulsion system of the vehicle to produce the commanded axle torque to maintain the set speed and applying a fading memory filter to the commanded axle torque to generate a filtered torque command. The method further includes determining an arbitrated torque command as a function of the filtered torque command and command the propulsion system of the vehicle to produce the arbitrated torque command. Also, the method includes determining that a slope of the road is greater than a predetermined slope threshold, setting a temporary set speed, and commanding the propulsion system of the vehicle to maintain the vehicle at the temporary speed.
