Abstract
The growing issues of energy shortage and the environmental crisis has resulted in new challenges for the automotive industry. Conventional commercial vehicles, such as refuse trucks and delivery vehicles, consume significantly more energy than other on-road vehicles since they have the characteristic of frequent start/stop with high moment of inertia and drive at low speeds on designated city routes. It is important to make these vehicles more fuel efficient and environmentally friendly. The hybrid commercial vehicle is a promising solution to reduce emissions and to meet the future vehicle emission standard since it is generally equipped with braking energy regeneration systems to recover the kinematic loss from frequent braking. This paper introduces a type of all-wheel drive hybrid concept suggested by Dr. Leo Oriet; the new concept allows commercial vehicles to have a significant improvement in kinetic braking energy recovery without sacrificing braking safety. Without mechanical connection involved to transfer energy within the powertrain, greater powertrain efficiency can be achieved. The research is based on the all-wheel drive with a two-axles regenerative braking strategy and driveline control unit. The vehicle model and driveline control unit were executed using AVL CRUISE to demonstrate its reliable braking energy regeneration system, effective energy management and emission reduction. Finally, the power system and engine operating condition, as well as vehicle driving mode, were analyzed after simulation to ensure the whole powertrain component functions together with high efficiency and significant reliability.
