Abstract: A system includes a generator and an engine coupled to the generator. The engine is configured to provide mechanical power to the generator. The system further includes a controller coupled to the engine and the generator. The controller is configured to: receive information regarding an engine operating parameter threshold value at which an engine operating parameter value failed to match a load demand value that is indicative of a load exerted by the generator on the engine, and set the engine operating parameter threshold value as a maximum allowable engine operating parameter value for the engine.

Abstract: An apparatus structured to control an electric vehicle accessory of an electric vehicle during a charge event includes a controller communicatively coupled to a battery and an electric vehicle accessory. The controller is structured to determine that the battery of an electric vehicle is undergoing a charge event, and based on determining that the battery of the electric vehicle is undergoing the charge event, place the electric vehicle accessory in an on-state during the charge event, and cause the electric vehicle accessory to recharge by absorbing energy from the charging station during the charge event.

Abstract: Methods and systems for operating a vehicle on a reduced traction surface are disclosed. A controller of the vehicle obtains at least one of: ambient information or GPS information, determines a derate increment size based on the ambient or GPS information, imposes a sustained derate by applying a torque limit on a braking torque of the vehicle based on the derate increment size in response to detecting a traction control event. The controller also determines a verification period and a derate reduction period based on the ambient or GPS information to reduce the sustained derate in response to detecting a lack of traction control event during the verification period at a rate determined by the derate reduction period.

Abstract: A system for a non-hybrid vehicle is provided. The system includes an electromagnetic device structured to couple to an engine and generate AC electrical power from the engine. The system also includes an AC-to-DC inverter structured to receive and change the AC electrical power to regulated DC electrical power. Additionally, the system includes an electrical path coupled to the AC-to-DC inverter and configured to provide the regulated DC electrical power directly to an electrically-powered accessory at or above 28 volts DC.

Abstract: The present disclosure provides an engine stop/start control system for a vehicle comprising a first engine restart module configured to set a restart frequency and duration of an engine in response to a sensed ambient temperature, a second engine restart module configured to control the engine in response to a sensed characteristic temperature associated with the engine, a third engine restart module configured to control the engine in response to occurrence or non-occurrence of at least one expected charging event along a predefined route, a fourth engine restart module configured to control the engine in response to a state-of-charge of an energy storage device, and a route optimization module configured to set and adjust a proposed route to a destination that results in reduced engine usage.

Abstract: Systems and methods to control the vehicle speed of a vehicle includes a controller communicatively coupled to a motor and a brake mechanism. The controller is structured to receive an indication of a desired change in the vehicle speed, activate a motor speed governor responsive to the brake mechanism being in a released state, adjust an output torque responsive to the vehicle speed, wherein as a load corresponding to the motor increases the vehicle speed decreases.
