Abstract: A combustion engine for a vehicle includes a first centrifugal device for varying timing of a first plurality of suction or relief valves with respect to the drive shaft. A driving disc is mounted idle on a first camshaft which controls the valves, and at least one driven disc is integral with the camshaft. Drive elements for transmitting motion from the driving disc to the driven disc are interposed between the two discs causing a relative rotation of the driven disc with respect to the driving disc when the rotation speed of the discs exceeds a predetermined threshold. A distribution system connects the drive shaft with the driving disc so as to cause the rotation thereof. A second gear meshes with a first gear so that rotation of the driving disc mounted on the first camshaft causes the rotation of the second camshaft to control other valves of the engine.

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.
