US 2021/0291068 A1 · MODEL VEHICLE STATE DETECTION AND DETERMINATION METHOD AND SYSTEM

Abstract

A method of determining a state of a model vehicle using an electric motor is provided. During a sample period, the method may include measuring raw variables, including determining a first and a second voltage relative to a battery ground. Further, the method may include extracting state variables from the first and second voltages. The measuring of the raw variables may be repeated until the end of the sample period. The method may also include determining a tentative state from the state variables. Still further, the method may include setting a model vehicle state equal to a tentative state if the tentative state is equal to a previous tentative state. Still further including actuating a model vehicle component based upon the model vehicle state and setting the previous tentative state equal to the tentative state. Additionally, the method may include repeating the process for another sample period.
