Abstract

An electric motor including a rotor, rotating about an axis of rotation, and a stator, coaxial to the rotor. The stator has a casing. A body incorporates a controller of the electric motor. The body is placed outside the stator and parallel to the axis of rotation in a position substantially tangent to the casing of the stator. The rotor includes a first and second cooling fan, keyed on respective first and second axial ends of the rotor, opposite along the axis of rotation. The first and second cooling fans generate respectively, with the rotation of the rotor, a first and a second flow of cooling air independent of each other. The first flow of cooling air is directed toward the first axial end of the rotor, and the second flow of cooling air is directed towards the body so as to cool down the controller.

Abstract

A method for the diagnosis of the offset of the resolver of an electric motor, comprising acquiring a predetermined offset of a resolver associated with the electric motor; in a first transient, supplying an excitation current to the phases of the electric motor. As a consequence of the excitation current, a current established on the axis d of minimum reluctance and a current established on an axis q in phase quadrature with respect to the axis of minimum reluctance are determined. The correctness of the offset of the resolver is diagnosed if the current established on the axis d in the first transient is higher than the current established on the axis d in the second or third transient, and if the current established on the axis q in the first transient is lower than the current established on the axis q in the second or third transient.

Abstract

A method calibrates an inertial-sensor device installed in an arbitrary position on board a vehicle and adapted to detect at least one entity indicative of vehicle dynamics along at least one direction of a local reference-coordinate system. The method includes steps of: acquiring by the inertial-sensor device at predetermined measuring times real-measured data indicative of the vehicle dynamics in the local reference-coordinate system; acquiring by a calibrating detector different from the inertial-sensor device, at sampling times coinciding with the measuring times, reference-measured data indicative of the vehicle dynamics in a vehicle-coordinate system; and generating a coordinate-transformation matrix adapted to correlate the entity measured in the local reference-coordinate system with a corresponding entity in the vehicle-coordinate system. Also, a sensor system of dynamics of the vehicle is able to be installed on board in an arbitrary position.

Abstract

A parking-assistant system for “multi-maneuver parking”, which is designed for generating, before the parking maneuver is started, a predetermined path, via the simulation of a maneuver of exit from a parking space. The control effected by the system, during the real parking maneuver, limits itself to comparing the effective position of the vehicle with respect to the predetermined path. Said control has somewhat low computational requirements so that the system is quite reliable.
