Embodiment Construction

[0013] This instruction manual is concerned with operating the drivetrain or drive train of a vehicle. The method may be applied to a drivetrain including an electric motor that selectively provides power to the drivetrain to provide propulsion to accelerate and decelerate the wheels. The drivetrain may also include another power source (eg, an internal combustion engine) to provide power to the drivetrain. engine can be figure 1 type shown in . The engine can be included in figure 2 and image 3 In a drivetrain of the type shown in . Alternatively, the engine may be included in other types of series and parallel hybrid powertrain configurations. The drivetrain can be based on Figure 5 and Figure 6 methods such as Figure 4 operation shown. Figure 5 and Figure 6 A method adjusts power output of an internal combustion engine to enhance power delivery to wheels during off-road conditions.

[0014] refer to figure 1 , an internal combustion engine 10 (which inclu...

Abstract

The disclosure provides a method and system for operating an off-road vehicle. Systems and methods for operating a hybrid powertrain or driveline that includes an engine and an integrated starter / generator are described. In one example, engine power is adjusted based on a time averaged transmission input shaft power so that the engine may operate in a power region where its performance is enhancedto support operation in an off-road environment.

Description

technical field [0001] The present description relates to methods and systems for operating a powertrain of a hybrid vehicle. The method and system are particularly useful for hybrid vehicles that can be driven off-road. Background technique [0002] Vehicles can sometimes be driven off-road for work and recreational purposes. The vehicle may experience slopes in terrain that do not exist on paved or dirt roads. Additionally, the vehicle may encounter rock formations, rivers, creeks and other natural obstacles that the vehicle's driver may wish to navigate. When the driver depresses the accelerator pedal, it may be desirable for the vehicle to respond with a substantial amount of torque so that the driver has confidence that the vehicle can clear obstacles in the vehicle's path. One way to provide access to a lot of torque is to install a large displacement engine in the vehicle. However, large displacement engines may consume large amounts of fuel during conditions wher...
