A vehicle control system includes one or more processors configured to assign plural vehicles to different groups in one or more vehicle systems for travel along one or more routes. The one or more processors also are configured to determine trip plans for the different groups. The trip plans designate different operational settings of the vehicles in the different groups at different locations along one or more routes during movement of the one or more vehicle systems along the one or more routes. The one or more processors also are configured to modify one or more of the groups to which the vehicles are assigned or the operational settings for the vehicles in one or more of the vehicle systems based on a movement parameter of one or more of the vehicle systems. The trip plans for the different groups of the vehicles are interdependent upon each other.

An EHC is configured to electrically heat a catalyst that purifies exhaust gas from an exhaust path of an internal combustion engine mounted on an electrically-powered vehicle, when a current passes through the EHC. A charger converts AC electric power supplied from an external power supply to a charging port into charging power of a power storage device by a power conversion path including an insulating transformer. The EHC is electrically connected to power lines which are provided on the primary side of the insulating transformer on the power conversion path, and to which a DC voltage is output. In a case where the EHC is operated when the vehicle travels, the charger converts the electric power from the power storage device into the DC voltage output to the power lines connected to the EHC, by a part of inverse conversion of power conversion at the time of external charging.

A system and method control a powered system having an engine configured to operate using a plurality of fuel types. A first set of control signals including a first set of valve signals are communicated to each fuel tank based at least in part on a first stored engine operating profile to control amounts of fuel provided from each fuel tank to the engine. A different, second set of control signals including a second set of valve signals are communicated to the fuel tanks based at least in part on a second stored engine operating profile to control or change the amounts of fuel from each fuel tank to the engine. The system and method can switch between operating conditions associated with different external domains to alter the engine operating profile used to control the fuel or fuels supplied to the engine.

A hybrid vehicle includes an internal combustion engine, a rotating electric machine, an electric storage device, a power supply device, and a controller. The controller executes switching control to switch from a first electric power supply to a second electric power supply by starting the internal combustion engine. The first electric power supply is the supply of electric power from the electric storage device to the electric device. The second electric power supply is the supply of electric power from the rotating electric machine to the electric device. The controller controls the power supply device and the internal combustion engine such that the internal combustion engine is started with the first electric power supply being continued during the switching control.

A method manages energy of a hybrid vehicle. The vehicle includes a heat engine, one or more electric traction motors, a high-voltage traction battery, a low-voltage on-board battery for accessories of the vehicle, a current inverter to transform direct currents into alternating currents for the electric motor, and a reversible current transformer to convert high-voltage current into low-voltage current of the on-board battery and to use a stock of energy available in the low-voltage battery to not draw energy from the high-voltage battery when it has a relatively low level of charge. The method includes determining an operating point of the vehicle involving a minimum fuel consumption in the heat engine by imposing on the electric motor a torque that minimizes a criterion of total fuel consumption by the consumption of the heat engine, power consumed in the traction battery, and power consumed in the on-board battery.

A cruising distance coefficient is set that is smaller than a value of 1 and that becomes smaller as a use index indicating a degree of use of external charging gets smaller, and a cruising distance is calculated by multiplying a fuel quantity by the set cruising distance coefficient and a fuel consumption coefficient. Then, a display cruising distance is calculated by subtracting from the cruising distance a value obtained by subtracting a set-time travel distance Lset, obtained when the cruising distance is calculated, from a travel distance from a travel distance meter, and the calculated display cruising distance is displayed on a display device in front of a driver's seat.

A control system identifies vehicle systems for combining into a larger convoy. Each the vehicle systems is formed from at least one propulsion-generating vehicle and at least one non-propulsion-generating vehicle. The control system directs the identified vehicle systems to couple with each other for travel as the convoy from a first location toward a different, second location. The control system directs a first vehicle system in the convoy to separate from the convoy and/or a second vehicle system to join the convoy by coupling with at least one of the vehicle systems in the convoy in an intermediate location between the first and second locations. The vehicles in each of the vehicle systems in the convoy remain connected during separation of the first vehicle system from the convoy and/or during joining of the second vehicle system to the convoy.

A battery module includes a sub module including a plurality of battery cells, a lower housing to receive the sub module therein and having an opening, a first housing cover coupled to the lower housing, covering the opening of the lower housing, and having a gas inlet, a second housing cover coupled to the first housing cover from above to form a gas receiving space therebetween, and having a gas outlet, and a variable partition structure using hinges installed in the gas receiving space to partition the gas receiving space to define a gas exhaust path to increase a movement path of a flame entering together with gas occurred in the sub module and entering the gas receiving space through the gas inlet.

The present disclosure generally relates to a system and methods for managing and controlling emissions produced by a vehicle and/or powertrain which includes one or more power sources selected from a fuel cell, a fuel cell stack, a battery, and combinations thereof, a processor, one or more inputs, a controller, and one or more emission control devices.

A self-charging all electric vehicle comprising three or four banks of batteries, FIG. 1 and FIG. 1A, to power in rotation, one or two at a time, the prime mover 12, a permanent magnet direct current motor. A three-wire direct current generator 13 which provides two 125 voltages to charge simultaneously two banks of batteries 10 and 250 volts to power the traction motors FIG. 4 and FIG. 5 for producing rotational energy. The generator is driven by the drive shaft of the prime mover.
