Abstract

An assembly including a transmission system, a braking system and a control system, for use in a motor driven vehicle. The assembly comprises a transmission system having drive means which provide an input 3 to an infinitely variable ratio gear assembly (100) and driven means coupled to be driven by an output (45) of the gear assembly (100) which responds automatically to variations in predetermined characteristics of or applied to the transmission system to vary the gear ratio between the drive and driven means; a braking system (70) having brake means, operable independently of the drive means; and a control system communicating between the braking system (70) and the transmission system and being responsive to actuations of the brake means to cause the gear ratio of the assembly (100) to be varied, preferably by decreasing to a lower ratio. <IMAGE>
