Abstract

An electronic system for stabilizing steering of a model vehicle may use different settings depending upon the RC model vehicle to be controlled. Different vehicles have different dynamic operation and responses and therefore may require different Electronic Steering Stability (ESS) system “settings”. The “settings” may be different “gains”, or different “coefficients” used with the control system algorithms. “Settings” may also mean that a completely different control algorithm may be used. For example, a vehicle A may be controlled adequately with a “P” control algorithm, while a vehicle B may require a complete “PID” control algorithm to be implemented.

Claims

a controller comprising a transmitter configured to transmit control signals to the model ground vehicle, wherein the transmitter comprises;

a steering control for steering the model ground vehicle;

wherein one of the settings comprises data representing the physical orientation of the receiver in the model ground vehicle;

wherein the transmitter is configured to transmit the settings stored in the transmitter memory to the receiver; and

wherein the receiver is configured to store the settings in the receiver memory, and then loads the ESS system with appropriate parameters from the settings in the receiver memory.
