Description:Complete Specification

The following specification describes and ascertains the nature of this invention and the manner in which it is to be performed.
Field of the invention
[0001] This invention relates to a hydrogen vehicle, and more specifically to a safety system for the hydrogen vehicle.

Background of the invention
[0002] US 2016171797 AA describes a system control method that is provided for measuring a distance between a smart key and a vehicle. When the distance between the smart key and the vehicle is changed based on a predetermined distance whether a hydrogen leak occurs is detected by a hydrogen sensor detection controller. A driver is then informed of a hydrogen leak via a display on a cluster, a turn-on of an emergency light, and a warning sound of the vehicle. Alternatively, a starting-impossible state of the vehicle or shutting-down starting of the vehicle is maintained to ensure safety measures based on the concentration of the leaking hydrogen.

Detailed description of the embodiments
[0004] Figure 1 illustrates a drawing depicting a canopy 110 containing a hydrogen sensor 130 that is positioned above a hydrogen engine 120 in one embodiment of the invention. A safety system 100 for a hydrogen vehicle is described. The safety system 100 comprises a canopy 110 positioned above a hydrogen engine 120 such that the canopy 110 that is positioned above the hydrogen engine 120 channels hydrogen gas that leaks from the hydrogen engine 120 towards a center of the canopy 110. The hydrogen sensor 130 is mounted at a center of the canopy 110 that is positioned above the hydrogen engine 120. The hydrogen sensor 130 senses a presence of hydrogen gas that leaks from the hydrogen engine 120 and is channeled towards the center of the canopy 110. An electronic control unit 140 is in electronic communication with the hydrogen sensor 130 that is mounted at the center of the canopy 110 that is positioned above the hydrogen engine 120. The electronic control unit 140 is adapted to receive a signal from the hydrogen sensor 130 if the hydrogen sensor 130 senses a presence of hydrogen gas that leaks from the hydrogen engine 120 and is channeled to the hydrogen sensor 130 that is positioned in the center of the canopy 110.

[0005] Figure 1 illustrates a drawing depicting the canopy 110 containing the hydrogen sensor 130 that is positioned above the hydrogen engine 120 in one embodiment of the invention. In an exemplary embodiment, the safety system 100 for a hydrogen vehicle is described. The safety system 100 comprises the hydrogen engine 120 and a plurality of hydrogen supplying modules (not shown) that are positioned in proximity of the hydrogen engine 120 and in flow communication with the hydrogen engine 120. A canopy 110 is positioned above the hydrogen engine 120 and receives hydrogen gas that leaks from the hydrogen engine 120. More specifically, the canopy 110 is positioned above the hydrogen engine 120 such that the canopy 110 that is positioned above the hydrogen engine 120 channels hydrogen gas that leaks from the hydrogen engine 120 towards a center of the canopy 110. Therefore, the hydrogen gas that leaks from the hydrogen engine 120 and from the plurality of hydrogen supplying modules that surround the hydrogen engine 120 rises upwardly towards the canopy 110 and are channeled due to the dome shape of the canopy 110 towards the center of the canopy 110.

[0006] In an exemplary embodiment, a hydrogen sensor 130 is mounted at a center of the canopy 110 that is positioned above the hydrogen engine 120. The hydrogen sensor 130 that is mounted at the center of the canopy 110 that is positioned above the hydrogen engine 120 senses a presence of hydrogen gas that leaks from the hydrogen engine 120 and is channeled towards the center of the canopy 110. Since the hydrogen sensor 130 is positioned at the center of the canopy 110, the hydrogen gas that leaks from the hydrogen engine 120 and from the plurality of hydrogen supplying modules that surround the hydrogen engine 120 is channeled to the center of the canopy 110 that is positioned above the hydrogen engine 120.

[0007] In an exemplary embodiment, an electronic control unit 140 is in electronic communication with the hydrogen sensor 130 that is mounted at the center of the canopy 110 that is positioned above the hydrogen engine 120. Once the hydrogen sensor 130 that is positioned at the center of the canopy 110 senses the presence of hydrogen gas that indicates a leak in the hydrogen engine 120 or from the plurality of hydrogen supplying modules that surround the hydrogen engine 120, the hydrogen sensor 130 transmits an electronic signal to the electronic control unit 140. The electronic control unit 140 is adapted to receive a signal from the hydrogen sensor 130 if the hydrogen sensor 130 senses a presence of hydrogen gas that leaks from the hydrogen engine 120 and is channeled towards the center of the canopy 110. Therein, the electronic control unit 140 transmits an electronic signal to an indicator, thereby notifying a user of the hydrogen leak that is detected from hydrogen engine 120 or from the plurality of hydrogen supplying modules that surround the hydrogen engine 120.

[0008] A working of the safety system 100 for the hydrogen vehicle is described as an example. When hydrogen gas leaks from one of the hydrogen engine 120 and from the plurality of hydrogen supplying modules that surround the hydrogen engine 120, the hydrogen gas is channeled via the dome shaped portion of the canopy 110 towards the center of the canopy 110. Therein, the hydrogen sensor 130 that is located at the center of the dome shaped portion of the canopy 110 senses the presence of hydrogen gas that has leaked from one of the hydrogen engine 120 and from the plurality of hydrogen supplying modules that surround the hydrogen engine 120. Once the hydrogen sensor 130 senses the presence of hydrogen gas that has leaked from the hydrogen engine 120 or from the plurality of hydrogen supplying modules that surround the hydrogen engine 120, the hydrogen sensor 130 transmits an electronic signal to the engine control unit 140. The electronic signal that is transmitted from the hydrogen sensor 130 to the engine control unit 140 is indicative of the presence of hydrogen gas that has leaked from the hydrogen engine 120 or from the plurality of hydrogen supplying modules that surround the hydrogen engine 120. Therefore, the user of the vehicle is notified that hydrogen gas has leaked from one of the hydrogen engine 120 and the plurality of hydrogen supplying modules that surround the hydrogen engine 120 and requires to be rectified.

[0009] It must be understood that the embodiments explained above are only illustrative and do not limit the scope of the disclosure. Many modifications in the embodiments with regard to dimensions of various components are envisaged and form a part of this invention. The scope of the invention is only limited by the scope of the claims.
