Abstract

A toy vehicle remote control transmitter unit wirelessly controls the movements of a programmable toy vehicle. The toy vehicle includes a motive chassis having a plurality of steering positions. A microprocessor in the transmitter unit emulates manual transmission operation of the toy vehicle by being in any one of a plurality of different gear states selected by manually operating a plurality of manual input elements mounted on the housing of the transmitter unit. Forward propulsion control signals representing different toy vehicle speed ratios associated with each of the gear states are transmitted from the transmitter unit to the toy vehicle. The motive chassis has a plurality of defined steering positions. The speed of changing from a current steering position of the motive chassis to a new steering position is dependent upon the physical relationship between the current and new steering positions.
