Steering control for self-propelled vehicles
First Claim
1. A steering control system for a self-propelled vehicle, comprising:
- a steering control comprising a gripping zone of elastically variable shape that can undergo a change in at least one of shape and volume;
at least one sensor provided in the gripping zone structured and arranged to react to said change in at least one of shape and volume of the gripping zone; and
at least one control or monitoring element for operating the self-propelled vehicle, the control or monitoring element being connected to the at least one sensor and being activatable by the at least one sensor;
wherein the at least one sensor comprises a hydraulic or pneumatic sensor comprising a tube filled with a fluid;
the tube extends over essentially an entirety of the steering control; and
the entirety of the steering control comprises a whole circumference of a steering wheel or a whole length of a handle bar,wherein the tube comprises a first material that is elastically deformable;
the tube is embedded in a second material that is elastically deformable; and
a final elasticity of the second material is equal to or less than an elasticity of the first material; and
wherein when an external pressure is exerted to the second material, said external pressure is immediately transmitted to the tube which in turn transmits said external pressure to the fluid contained inside the tube.

Abstract
A steering control for vehicles, such as for automobiles or motorcycles in the form of a steering wheel or of a handlebar, with a gripping zone presenting an elastically variable geometry deformable under the action of the hand or the hands of the driver gripping the steering control fast and forcefully in case of danger. Thus, in the event of panic, an hydraulic or pneumatic sensor located inside the gripping zone is activated. The sensor extends over essentially the whole gripping zone of the steering control that can be gripped by at least one hand of the driver, and includes a tube of elastic material, filled with a liquid, and embedded entirely in a foamed plastic material. The steering control exhibits then high effectiveness and reliability of a safety device, in the elimination of potential danger caused by mistaken reactions of the driver, and in the economic feasibility of the inventive device.

18. A steering control system for a self-propelled vehicle, comprising:
-
a steering control comprising a deformable gripping zone; a sensor provided in the gripping zone structured and arranged to react to a change in at least one of shape and volume of the gripping zone; and a control or monitoring element for operating the self-propelled vehicle, the control or monitoring element operatively connected to the sensor; wherein the steering control comprises a steering wheel comprising a frame surrounded by foam; the sensor comprises a tube embedded in the foam; the tube extends around substantially an entire circumference of the steering wheel; a first end of the tube is sealed; a second end of tube opposite the first end is coupled to a pressure gage and a signal transmitter for analog electric measuring values; the tube comprises at least one of silicon and vinyl-ethylene acetate; a final elasticity of the foam is less than an elasticity of the tube; the sensor is a hydraulic sensor and the tube is filled with a fluid; the fluid is essentially incompressible; and the pressure gage is calibrated such that it the pressure gage emits a signal only when a pressure increase in the tube exceeds a predetermined value.
