DESC:FIELD OF INVENTION

The present invention relates to automobile movement by using gravity. In particular, the present invention relates to the technology for fuel-supply to moving automobiles. More particularly, the present invention relates to optimally supply fuel to automobiles running at high-speed and down the hilly terrains by using the gravity force.

BACKGROUND OF THE INVENTION

In mechanics, gravity means the phenomenon by which massive bodies are attracted to one another. In popular usage, the term “gravity” is often used to describe the force of attraction itself, but technically “gravitation” is the force and “gravity” is the observed effect of this force.

PRIOR ART

US6276700B1 discloses a gravity driven steerable wheeled vehicle for recreational use, most particularly on surfaces such as pavement, artificial hard-pack turf, mountain slopes, dirt roads, grass and hard-packed snow. The vehicle has at least three (3) but preferably four (4) wheels which may or may not be on independent axles one from the other and which may or may not be each independently shock suspended. There is also a steering mechanism for steering the vehicle and a driver compartment portion for containing a driver of the vehicle in a prone face-down and face-forward position. The vehicle is steerable by the driver from the prone face-down and face-forward position. The vehicle may further have braking system for slowing or stopping the vehicle and a harness apparatus for harnessing the driver onto and into the vehicle.

US6672602B2 discloses a gravity driven steerable vehicle having wheels, or skis or a combination of wheels and skis for recreational use, most particularly on surfaces such as pavement, artificial hard-pack turf, mountain slopes, dirt roads, grass and hard-packed or non-packed snow. The vehicle has at least three (3) but preferably four (4) wheels, or skis or a combination of wheels and skis which may or may not be on independent axles one from the other and which may or may not be each independently shock suspended. There is also a steering mechanism for steering the vehicle and a driver compartment portion for containing a driver of the vehicle in a prone face-down and face-forward position. The vehicle is steerable by the driver from the prone face-down and face-forward position. The mechanism for suspension of the wheels and/or skis is configured to provide precise control in turns especially the carving of turns, by the skis, while descending on snow covered terrain. The attitude of the skis relative to the snow surface changes upon initiation of a turn and while in the turn to increase the edging of the skis thereby enhancing the turning characteristics of the vehicle. The vehicle may further have a braking system for slowing or stopping the vehicle and a harness apparatus for harnessing the driver onto and into the vehicle.

DISADVANTAGES WITH THE PRIOR ART

The following are the disadvantages with the prior art discussed above:

However, the prior art documents described above use the gravity force for performing steering control and stopping mechanism. It does not control the fuel-supply for adjusting it by gravity feed and inertia of the motor vehicle.

Further, Engine Control Unit (ECU) and Transmission Control Unit (TCU) act to control and command, which in turn learn all functions from various units. So, the motor vehicle is accelerated, when it is driven at higher speeds.

Moreover, both the prior art documents concern vehicle driven in dirt, grass or snow, in which driver is in a prone, face down and face forward position to drive racing vehicles or cart and which are not the motor vehicles covered by the present invention.

OBJECTS OF THE INVENTION

Some of the objects of the present invention - satisfied by at least one embodiment of the present invention - are as follows:

An object of the present invention is to provide an automatic and semi-automatic vehicle using gravity force to be controlled by a Transmission Control Unit (TCU).

Another object of the present invention is to provide a motor vehicle for optimum fuel-supply controlled by gravity force and inertia thereof while running under high-speed.

Still another object of the present invention is to provide a motor vehicle moving by the gravity force while running downhill.

Yet another object of the present invention is to provide a motor vehicle moving by the gravity force for easy control thereof.

A still further object of the present invention is to provide a motor vehicle moving by the gravity force for increasing efficiency thereof.

These and other objects and advantages of the present invention will become more apparent from the following description, when read with the accompanying figures of drawing, which are however not intended to limit the scope of the present invention in any way.

Typically, the drive shaft is disengaged from the drive line for about 0.15-0.25 microseconds, preferably for 0.2 microseconds during which the vehicle moves solely by inertia of the vehicle or by gravity to reduce vehicle speed to a speed well within the threshold speed.

BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS

The present invention will be briefly described with reference to the accompanying drawings, wherein:

Figure 1 shows a schematic diagram of the motor vehicle moving by the gravity force under high-speed or moving downhill and configured in accordance with the present invention.

DETAILED DESCRIPTION OF THE ACCOMPANYING DRAWINGS

In the following, the device for moving a motor vehicle by the gravity force under high-speed or moving downhill and configured in accordance with the present invention will be described in more details with reference to the accompanying drawings without limiting the scope and ambit of the present invention in any way.

Figure 1 Shows a schematic diagram of the device for moving a motor vehicle by the gravity force under high-speed or downhill and configured in accordance with the present invention. It is connected to wheels W1, W2 driven by an engine ENG via a clutch CL and gear box GB connected to a propeller shaft PS. An engine control unit (ECU) is connected to the gear box GB via a gear lever GL, an accelerator Acc and a common rail R fitted with a plurality of injectors on the engine ENG. ECU is also connected to two solenoids S1 and S2 fitted on the axle carrying the wheels W1, W2. The propeller shaft PS is connected to the wheel-assembly via a differential housing DH. The solenoid position may vary based on the feasibility to cut-off the drive.
The existing motor vehicle ECU cluster already includes the peripherals like, gear lever position, accelerator pedal position, vehicle speed, ECU, fuel injection system and solenoid operated electromagnets. Here, the complete drive is cut-off during operation at higher speed and the vehicle speed is increased for about 0.2 microseconds, only due to inertia of the vehicle.

WORKING PRINCIPLE OF THE INVENTION

There are two broad stages for working the motor vehicle configured in accordance with the present invention:

Stage 1:

1) ECU acquires the gear lever operating position and accelerator pedal position (which is already available in existing vehicles).

2) Gear lever operating positions include a neutral gear or a top gear.

3) Accelerator pedal position includes either 0% accelerator pedal pressing (no acceleration) or 100% accelerator pedal pressing, i.e. full throttle-on position.

Stage 2:

1) ECU issues commands to the solenoids or electromagnets.

2) Solenoids are controlled by the ECU depending on the accelerator pedal position and gear lever position.

3) In case, the solenoid receives no signal, the electromagnet disconnects the drive shaft from the drive line.

Accordingly, the operation of the mechanism devised as per the invention is operated as given below:

a) If the accelerator pedal is detected to be pressed 100%, i.e. vehicle is running in top gear:

- Accelerator pedal in maintained in this position for 6 to 12 seconds.

- Electromagnet is activated depending on the ECU signals received for about 0.5 to 3 micro seconds.

- The wheels are disengaged from the drive shaft and an optimum fuel-consumption is recorded.

For example:

• An accelerator pedal position is maintained for 3 seconds while driving on a highway, i.e. at 100%.

• ECU would capture the accelerator pedal position and cut off the drive for just 0.2 microseconds.

• Due to complete disengagement of the vehicle from its driving mechanism, the vehicle solely moves by gravity force for this 0.2 microsecond duration.

• This drive cut-off further enhances the acceleration of the vehicle, which is only for about 0.2 microseconds.

• The moment vehicle speed start to dip, the fuel is injected again to maintain the vehicle speed.

b) If the accelerator pedal is detected to be pressed 100%, i.e. vehicle is running in top gear:

- Operating the vehicle continuously beyond its threshold limit, e.g. at 160 km/hour for 5 minutes.

- Activate the electromagnets and cut-off the fuel supply to safeguard the vehicle components.
