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.

Claims

1. An autonomous control system applicable to hybrid and/or electric vehicles to make use of regenerative energy created when braking in each wheel with the aim of charging the automobile battery comprising a sensor for each wheel, which in combination with a secondary battery and a capacitor bank, powers the electric motors located in each wheel, which control the servo steering, servo brakes and traction motors as well as stabilising the peaks of regenerative current created when braking the vehicle with these electric motors working like dynamos, in combination with the autonomous control system, which is activated when the main battery fails.

2. The autonomous control system (ACS) according to claim 1 wherein the ACS comprises:

a gateway and controller of the EPCs, powered by the secondary battery

electronic power and control unit (EPC) applied to the steering and pedals,

interface of the previous unit, located on the steering Wheel and

automated wheel controller device (one for each wheel).

3. The autonomous control system according to claim 1 wherein the ACS can work directly from the capacitor bank, powering the electric motors of the servo steering, servo brakes and traction, or the regenerative energy can charge the secondary battery, which then works supplying power to the electric motors located in each wheel, activating the servo steering and servo brakes.

4. The autonomous control system according to claim 1 wherein regenerative energy created when braking the vehicle is used to power other services such as lights, electric windows, general vehicle electronics, without having to pass through the main battery.

5. The autonomous control system according to claim 1 wherein the vehicle includes two cables, one for the protection signal at 300 volts powered by the main battery and another 12 volt cable supplied by the secondary battery.

6. The autonomous control system according to the claim 1 wherein the system is installed in each wheel.

7. The autonomous control system according to claim 1 wherein alternatively the system is installed on the platform.
