Various methods and systems are provided for an auxiliary power unit of a vehicle. In one example, a system for a vehicle having a main power unit (MPU) coupled to an alternator and an auxiliary power unit (APU) configured to provide power to one or more hotel loads of the vehicle comprises: a controller with computer readable instructions stored in non-transitory memory executable to initiate operation of the APU in response to a drain load being applied to a battery of the vehicle that will deplete the battery to a state of charge (SOC) level that is less than a determined SOC threshold level in less time than a determined period, and the MPU is not in operation.

Method and systems for an auxiliary power unit

Various methods and systems are provided for an auxiliary power unit of a vehicle that provides electrical power and compressed air while a main engine of the vehicle is not running. In one example, an auxiliary power unit (APU) comprises: an engine, an alternator, and a compressor, all mounted to a common base frame in a triangular arrangement with the alternator and compressor arranged adjacent to one another and each of the alternator and compressor rotationally coupled with the engine through a gearbox spaced between the engine and each of the compressor and alternator.

A bus assembly is provided having a bus bar with first and second conductive layers extending along an insulator sheet interposed between the first and second conductive layers. The first and second conductive layers are partially aligned with respect to each other to form a first overlap region of the insulator sheet. The bus assembly includes a first set of arms having a set of diodes and a second set of arms having a set of switches. The bust bar includes a plurality of bus links coupling the plurality of arms to the bus bar forming a plurality of inverters. Each of bus links include a respective first bracket and a respective second bracket aligned with each other forming a second overlap region of the insulator sheet. The first bracket is electrically coupled to the first conductive layer and the second bracket is electrically coupled to the second conductive layer.

A vehicle control system determines a predicted location of wheel slip for an upcoming trip of a vehicle system by comparing a vehicle characteristic, route characteristic, and/or weather characteristic associated with the upcoming trip with a vehicle characteristic, route characteristic, and/or weather characteristic associated with a previous detection of wheel slip. Movement of the vehicle system is controlled during the upcoming trip by reducing tractive effort generated by a leading vehicle of the vehicle system relative to a trailing vehicle of the vehicle system during movement over the predicted location, reducing tractive effort generated by a leading axle in a vehicle of the vehicle system relative to a trailing axle of the vehicle during movement over the predicted location, and/or directing an adhesion modifying device to automatically dispense an adhesion modifying substance onto the predicted location.
