I.D.# C0833Printable Description
Duration: 2 Days

Considerable attention has been given to the design and efficiencies of electric hybrid propulsion systems and energy storage technologies. Although they draw much less attention, hydraulic hybrid propulsion and regenerative braking systems for road vehicles are a cost effective alternative to electric systems and have relevance to important sectors of the passenger and commercial vehicle markets.

In this two-day seminar, hydraulic hybrid vehicle systems and their potential will be examined using model based evaluations. This will include an evaluation and comparison of hybrid configurations as well as the introduction of components used in these hydraulic hybrid systems. Also provided will be details on how hydraulic systems are designed and integrated into vehicles, including interactions with braking systems and various other vehicle systems. Recent developments in hydraulic machines and an update on the component technology needed to implement these solutions will also be presented.

Learning Objectives
By attending this seminar, you will be able to:

  • Identify the fundamentals of parallel and series hydraulic hybrid vehicle transmission systems and components
  • Evaluate the applicability of such systems to particular vehicle applications
  • Identify how hydraulic hybrid system components can be integrated into the vehicle
  • Recognize the interactions with other vehicle systems (e.g. engine, transmission, ABS, foundation brakes) and integration of controls

Who Should Attend
This course will benefit individuals new to hydraulic hybrid systems as well as engineers and designers involved in all areas related to the design and development of vehicle powertrain systems. Also benefiting will be individuals interested in the interaction of this hybrid system with braking systems and engine controls.

Prerequisites
An undergraduate degree or strong technical background is highly recommended. A basic familiarity with vehicle powertrain and braking systems is required.
