Abstract: A system for dynamically braking an electrically driven vehicle wherein a retarding means is directly coupled to the engine/generator drive and employed to absorb the major portion of the energy produced during power regeneration. Running at near rated engine speed, the retarding means generates substantially constant braking torque during vehicle deceleration and associated control systems automatically operate the retarding means in response to command signals and employ circuits to maintain the excitation of generator below that of the wheel motors during retarding whereby better power transfer is effected.
