These and other results are obtained according to the present invention by a device of the above kind wherein acceleration is obtained by a circular rotative element, preferably provided and fixed under the steering wheel, and following its steering movement, permitting acceleration on the basis of the vehicle direction, without losing gripping action and direction on the steering wheel, and making it possible maintaining when necessary both hands on the steering wheel. The solution according to the invention is particularly, but not exclusively advantageous when driving along mixed mountain roads.
It is therefore specific object of the present invention an electronic manual acceleration device for a vehicle provided with a steering wheel, said device providing at least a first element, or covering element, or little wheel, having a circular sector shape, at least a second element, sliding coupled with said first element or little wheel, and integral with said steering wheel, acceleration being obtained by rotating, rightward or leftward, said first element, following the steering movement of the steering wheel, thus permitting acceleration on the basis of vehicle direction, without losing grip on the steering wheel and direction, being it possible, when necessary, keeping both hands on the same steering wheel.
In a first embodiment of the device according to the invention, two circular sector first elements and two corresponding second elements are provided.
In a second embodiment of the device according to the invention, said first element or little wheel and said second element are comprised of a full circle.
Preferably, according to the invention, said device is applied behind said steering wheel.
Furthermore, according to the invention, said device can be provided in front of said steering wheel.
Particularly, according to the invention, rotation coupling between said first element and said second element is obtained by projections realized on said second element and a sliding channel realized on said first element.

Observing first figure 1 , it is shown a first embodiment of a manual acceleration device according to the invention, mounted behind the steering wheel (not shown in this as well in the others figures), providing a first circular element 1 , or covering element, or little wheel, sliding coupled with a second circular element 2.
Said second circular element 2, preferably comprised of sheet, is integral with steering wheel. Rotating coupling between element 1 and element 2 is obtained by projections realized on circular element 2 and a sliding channel realized on little wheel 1.
Device 1 according to the invention provides acceleration by rotating little wheel 1 about its own symmetry axis and with respect to steering wheel.
Starting from a quiet position, to accelerate, little wheel 1 is rotated with respect to steering wheel, either in a clockwise direction or in an anticlockwise direction, against the force of a spring (not shown in figure 1).
Acceleration is proportional to rotation amount, so that maximum acceleration is obtained when rotation reaches a limit angle set by designer of the device (e.g. 5°).
In case acceleration has been obtained by rotating little wheel 1 according to a direction, its reverse rotation reduces acceleration up to reaching a zero value in correspondence of quiet position.
In case little wheel is left by the user, it goes back to the quiet position by the action of return spring, or of other suitable means, not shown.
Second circular element 2 is fixed to the steering wheel by clamps, or by another system, also not shown in the figures.
Observing now figure 2, it is shown another embodiment of the manual acceleration device according to the invention, wherein a layer 3, made up of Teflon®, or of another material having similar sliding properties, is provided between said little wheel 1 and said second circular element 2, and a further sheet element 4, between said layer 3 and said little wheel 1.
Sliding between said further sheet element 4 and said layer 3 is obtained by sliding slots and radial bearings.
Transmission of motion, and transformation of the same into acceleration, is obtained by a potentiometer 5.
Idle pins 6 are housed in suitable holes on said second circular element 2, said pins 6 having one end coupled to a groove obtained within the little wheel 1 , so as to obtain a circular relevant movement between said second circular elements and the little wheel 1.
A tracer point, not shown, is provided on said steering wheel 1 , said tracer point, sliding on potentiometer 5, permitting recognizing position between second circular element 2, integral with the steering wheel, and the little wheel 1.
Said information is sent to a suitable electronic unit (not shown), processing the signal and transmitting the acceleration control to the vehicle electronics.
Return of little wheel 1 in the quiet position, or "not acceleration position" occurs by the action of two return springs, not shown, one for clockwise rotations and the other one for anticlockwise rotations, respectively.
Position of the little wheel can be monitored by any instrument suitable for said function (e.g. electric systems, magnetic systems, video systems, mechanical systems, mixed systems, etc.).
In the third embodiment shown in figure 3, manual acceleration device according to the invention provides, instead of the little wheel 1 and the second circular element 2, two circle sectors 1', 11", and two sectors of said second circular element 12', 12".
The present invention has been described for illustrative, but not limitative purposes, according to its preferred embodiments, but it is understood that variations and/or modifications can be introduced by those skilled in the art without departing from the relevant scope, as defined in the enclosed claims.
