Abstract: A system includes a first heater positioned in or proximate to an exhaust aftertreatment system in exhaust gas-receiving communication with an engine, a second heater positioned downstream of the first heater, and a controller coupled to the first and second heaters. The controller is structured to determine, based on information indicative of a temperature regarding the exhaust aftertreatment system, that the temperature is below a temperature threshold; receive information regarding a characteristic of a battery coupled to the first heater and the second heater; control the temperature regarding the exhaust aftertreatment system without using the first or second heaters in response to determining that the characteristic of the battery is below a first threshold; and control a temperature regarding the exhaust aftertreatment system using the first heater in response to determining that the characteristic of the battery is above the first threshold but below a second threshold.

Abstract: Platooning vehicles can result in operational cost savings. Disclosed is a method of apportioning costs that are incurred/saved as a result of platooning vehicles, as well as assigning penalties for unfair platoon participation. For example, platooning history of a vehicle can be tracked, and if that vehicle acts too often as a trailing vehicle in a series of platoons then a penalty might be assigned to that vehicle. Also disclosed is a technique for operating a platoon in the presence of external factors such as municipal regulations, merging traffic, emergency vehicles, etc.

Abstract: A system and method are disclosed for improving the performance of an aftertreatment system by elevating its temperature above an activation temperature. According to at least one aspect of the present disclosure, the method includes injecting a quantity of a fuel into certain fueled cylinders of a plurality of combustion cylinders of an internal combustion engine, the plurality of combustion cylinders further including non-fueled cylinders. Exhaust from the fueled cylinders is directed through the aftertreatment system while uncombusted gas from the non-fueled cylinders is directed away from the aftertreatment system. In certain embodiments, the uncombusted gas may be directed into an intake manifold in fluid communication with the plurality of combustion cylinders through an orifice. The system includes an engine having exhaust valves to control flow of the exhaust and uncombusted gas and a controller configured to perform the operations of the method.

Abstract: A system includes an intake heater positioned in or proximate to an air intake of an engine, an aftertreatment system heater positioned downstream of the engine, and a controller coupled to the intake heater and the aftertreatment system heater. The controller is structured to operate the intake heater to heat air entering the engine for a predefined time period. The controller is structured to determine, based on information indicative of a temperature regarding an exhaust aftertreatment system, that the temperature regarding the exhaust aftertreatment system is below a predefined temperature threshold. The controller is structured to continue operating the intake heater after the predefined time period responsive to the temperature regarding the exhaust aftertreatment system being below the predefined temperature threshold.

Abstract: System, apparatus, and methods are disclosed for identifying passing opportunities for a vehicle and controlling the vehicle in response to the passing opportunities. For example, operation of one or more components of the vehicle can be changed in advance of attempting the pass to better prepare the vehicle for acceleration to initiate and complete the pass attempt. Operation of one or more components of the vehicle can be changed during passing to assist the vehicle in completing the pass.

Abstract: An electric vehicle includes an electric motor switchable between a first mode with a first number of poles and a second mode with a second number of poles less than the first number of poles, a plurality of inverters coupled to the motor, and a control module coupled to the plurality of inverters. The control module receives current vehicle information, determines that a mode switch is required between the first and second modes of the motor based on the current vehicle information, wherein the first mode achieves higher torque than the second mode, and performs the mode switch by controlling the plurality of inverters.

Abstract: Systems and methods for triggering and issuing safety warnings, including a risk-assessment system that collects movement data pertaining to each of a plurality of subsystems including one or more slow-moving subsystems (SMSSs) and/or one or more fast-moving subsystems (FMSSs). The risk-assessment system identifies, based at least in part on the collected movement data, an instance in which each of a set of warning-triggering conditions is true. The set includes (i) that a likelihood of a collision occurring among an identified subset of the plurality of subsystems is greater than a collision-probability threshold and (ii) that at least one of the subsystems in the identified subset has at least one current movement anomaly. In response to identifying the instance, the risk-assessment system issues at least one warning to at least one of the subsystems in the identified subset.
