A method for inertia drive control is provided. The method includes performing advanced inertia drive control by an inertia drive controller. The controller detects a speed reduction event during road driving of a vehicle, lane division together with road type division for a road, and performs inertia drive control guide and the inertia drive control based on drive conditions of lane change and lane maintenance.

Aspects of the present invention relate to a method and to a control system for controlling an engine and an electric traction motor of a vehicle, the control system comprising one or more controllers, wherein the control system is configured to: receive an indication of engine speed during engine idling; and control the electric traction motor to reduce a difference between the engine speed and an engine idle speed target

A work vehicle includes a main frame. The main frame is configured to selectively receive one of a first type of power source and a second type of power source. The first type of power source is different from the second type of power source. A traction motor is connected to the main frame and is configured to be driven by the one of the first type of power source and the second type of power source. A wheel is connected to the main frame and is configured to be driven by the traction motor.

A method is provided for scheduling regenerative braking torque, including: sensing a position of an accelerator pedal; generating a torque request value in response to the sensed accelerator pedal position; determining a speed of operation of a motor/generator; determining a torque limit in response to the torque request value and the determined speed of the motor/generator; generating a regenerative braking command in response to the torque limit; and outputting the regenerative braking command to the motor/generator.

There is provided a hybrid vehicle to suppress hunting (inversion) of a drive mode in a short time. The hybrid vehicle has an engine, a motor, a battery, an air conditioning system configured to condition air in a passenger compartment, and map information, and sets a drive route from the present location to the destination, and creates a drive support plan in which one of the drive modes including CD mode and CS mode is assigned to each drive section of the drive route to perform the drive support control. The drive support plan is created based on the battery remaining capacity taking into account the power consumption of the air conditioning system. When the predetermined condition that is based on the battery remaining capacity without taking into account the power consumption of the air conditioning system is satisfied while performing the drive support control, the driving state is continued.

A power delivery system includes a first inverter, a second inverter, and a turbocharger assist device. The first inverter is electrically connected to a primary bus and configured to receive electric current from an alternator via the primary bus to supply the electric current to a first load. The alternator generates the electric current based on mechanical energy received from an engine. The second inverter is electrically connected to a secondary bus discrete from the primary bus. The turbocharger assist device is mechanically connected to a turbocharger operably coupled to the engine. The turbocharger assist device is electrically connected to the secondary bus and configured to generate electric current based on rotation of a rotor of the turbocharger. The second inverter is configured to receive the electric current generated by the turbocharger assist device via the secondary bus to supply the electric current to a second load.

A saddle riding vehicle includes: an engine disposed between a front wheel and a rear wheel; a fuel tank disposed above the engine; a generator mounted to a crankshaft of the engine; and an inverter that supplies output of the generator to a battery. The inverter is disposed behind a head pipe, above a crankcase and below the fuel tank.

Methods and systems are provided for diagnosing leaks/degradation in a fuel system. In one example, a system for a vehicle may comprise a variable volume device disposed within a fuel tank; an atmospheric port of the variable volume device fluidly coupled to a vent line upstream of a hydrocarbon sensor housed in the vent line, the vent line coupling a fuel vapor canister to atmosphere; and a controller storing instructions for monitoring output of the hydrocarbon sensor; and generating an indication of a degradation in the variable volume device based on the monitored hydrocarbon sensor. In this way, it is possible to effectively detect a degradation/leak in the variable volume device with minimal specialized components in the fuel system.
