ABSTRACT
This chapter discusses the design principle of an off-road hybrid electric tracked vehicle, focusing on power ratings of the traction motor, engine/generator, and energy storage for satisfying specified vehicle performance indices, such as gradeability, acceleration, and steering on various types of ground. Off-road vehicles (military, agricultural, and construction) usually operate on unprepared ground and need to overcome very complex and difficult ground obstacles, such as steep grade and very soft ground. Depending on the functional requirements, different criteria are used to evaluate the performance of various types of off-road vehicles.
