Vehicle traction control system having separate power sources for front and rear wheels controlled according to static and dynamic state

摘要

The traction control system is designed for a four-wheel drive vehicle with a first power source (14,16) for driving either the front (66,68) or rear (80,82) set of wheels and a second power source (20) for driving the other set. The front wheel drives can be in the form of different types of power sources, while the rear wheel drive comprises at least one electric motor (70). The wheel drives are controlled according to the static and dynamic state of the vehicle so that the sum of the front and rear drives is equal to the power required by the operator or driver to propel it, and governed by a manually-operated accelerator.
