Abstract
A control system for an electrically-actuated, rideable saddle vehicle including an electric traction motor and a vehicle control system having two different speed acquisition systems. A first speed system includes a position sensor and controls power to the motor on a basis of a control signal, which is characteristic of torque selectively required by the electric motor. A second speed system includes Logic circuitry for estimating vehicle speed from estimated variations of a counter-electromotive force generated in the stator winding as a result of the rotor movement of the motor. The two systems allow optimizing control of the motor from both speed systems, or from that considered more reliable in a given operating condition, during operation of the vehicle. Illustratively, for low speeds, speed control may be based on sensor signals in the first speed system, while high speeds control may be based on the estimates from the logic system.
