Problems solved by technology

In practice, however, the complexity of the interaction between PCC control and ICM control, and its interaction with other powertrain and vehicle system controls, can be surprisingly detrimental to any fuel consumption benefit and may actually increase fuel consumption

Embodiment Construction

[0021] see figure 1 , shows a schematic diagram of an exemplary vehicle 100 including a powertrain 102 incorporated within the vehicle 100 . In the illustrated embodiment, the powertrain 102 includes a prime mover 104 , such as an internal combustion engine, structured to generate power for the vehicle 100 . The powertrain 102 also includes a gearbox 106 coupled to the prime mover 104 to adjust the output torque of the prime mover 104 and transmit the output torque to a driveline 107 including a drive shaft 108 . In the illustrated embodiment, transmission 106 may be disengageably connected to engine crankshaft 105 via clutch 109 . In other embodiments, the gearbox 106 may be disengageably connected to the engine crankshaft 105, and the engagement and disengagement may be by operation of a master clutch located in front of the gearbox, by placing the gears in neutral through the gearbox Or by other clutch and / or gear arrangements. Various embodiments contemplate that the tr...

Abstract

A powertrain includes a prime mover and an electronically controllable clutch. The powertrain structured selectably engages the clutch to provide power from the prime mover to drive one or more groundcontacting wheels and to selectably disengage the clutch to decouple with one or more ground contacting wheels. The electronic control system operatively communicates with the prime mover and the electronically controllable clutch, and uses a predictive cruise control (PCC) controller and an idle coast management (ICM) controller, to control vehicle speed during concurrent operation of the PCC controller and the ICM controller.

Description

Background technique [0001] The present application relates to optimization of parallel operation of predictive cruise control and idle coast management control. Predictive cruise control (sometimes referred to herein as "PCC") generally involves being configured to provide cruise control vehicle speed set point changes based on current or projected vehicle mission parameters in order to reduce fuel consumption or increase fuel economy A type of control. PCC control components may reside in controllers embedded in engine control systems, transmission control systems, other vehicle control systems, and combinations thereof. Idle coasting management control (sometimes referred to herein as "ICM") generally involves being configured to control the engagement and disengagement of the vehicle's wheels with a vehicle prime mover, such as the engine, in order to reduce fuel consumption based on current or projected vehicle mission parameters. A type of control that consumes or incr...
