Abstract: Steering boxes currently available on the market in order to convert the rotation of the steering wheel into the angular rotation of the wheels are not suitable to be partially built into the rim of the wheels of an electric car. In addition, existing boxes do not allow the independent rotation of the wheels or wide turning radii. These limitations are overcome using a system comprising: a body into which at least one motor is built using corresponding supports, which motor(s) actuate(s) the steering rotation axle of each steered wheel in the upper part of the body, and, in the lower part, a transmission gearbox and a stationary circular crown gear with which driving pinions mesh, said pinions rotating about the crown gear, thereby rotating the entire body and the rotation axle of the wheel built into the body together with suitable means.

Abstract: The regenerative energy produced during the braking of a vehicle is used for powering a secondary battery, that is independent from the main battery, and, in the event of a complete failure of said main battery, allows the continued operation of the basic services such as power steering, lights, the brake servo unit, and electronics, as a result of the combined action of said autonomous system that includes a capacitor bank which powers said services either directly or via the secondary battery. The system comprises an interface of the electronic power and control unit, an electronic power and control unit, applied to the steering and pedals, and an ECU power controller and port.

Abstract: The invention concerns a sequential safety system associated with a moving closing panel driven so as to slide by an electric motor (6), this safety system including means (20) exploiting the signal originating from an optical fiber to stop and reverse the direction of movement of said moving panel in the event of a change in the signal, as well as additional safety means allowing the end-of-travel positions of the moving panel to be determined without ambiguity via the joint exploitation of the results derived from measuring the frequency of the pulses caused by the rotation of the electric motor (6) driving said moving panel, as well as data originating from the optical fiber.
