Adaptive torque operating system and electric motor control apparatus
An apparatus transforms vehicle operator intentions to wheel propulsion controls using an operator interface, sensors, a torque budgeting circuit, at least four motor controllers, and a vehicle/operator personality profile store. The store provides instructions and parameters which control dynamic vehicle responsiveness and reflect an operator's personality. The instructions and parameters are accessible by an application programming interface (API). Vehicle characteristics may be recorded by operating the vehicle through a prescribed route or evolution. A revised performance profile of a vehicle can be installed when the vehicle is reconfigured. Performance of a vehicle is modified to mimic a different vehicle by installing a new software dynamic performance profile. The API enables an open architecture for developers to customize vehicle dynamics without cutting metal.
