Toy vehicle wireless control system
First Claim
1. A toy vehicle remote control transmitter unit comprising:
- a housing;
a plurality of manual input elements mounted on the housing for manual movement;
a microprocessor in the housing operably coupled with each manual input element on the housing;
a signal transmitter operably coupled with the microprocessor to transmit wireless control signals generated by the microprocessor; and
wherein the microprocessor is configured for at least two different modes of operation, the microprocessor being configured in one of the at least two different modes of operation to emulate manual transmission operation of the toy vehicle by being in any of a plurality of different gear states and to transmit through the transmitter forward propulsion control signals representing different toy vehicle speed ratios for each of the plurality of different gear states, the microprocessor further being configured to be at least advanced through the plurality of different consecutive gear states by successive manual operations of at least one of the manual input devices.

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 an operation of manual input elements on 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 steering feedback sensor with a plurality of defined steering positions to vary rate of steering position change to avoid overshoot.
