DETAILED DESCRIPTION

[0001] Generally, a display device, also known as instrument cluster, is placed on a vehicle to display vehicle parameters. The display device on the vehicle, displays information related to the vehicle, to a user of the vehicle. Now-a-days, the display device in the vehicle interacts with a user device to give enhanced features, better and comfortable riding experience to the user of the vehicle. The two-wheeled vehicles available in the market usually have a single display device which is programmed to indicate various vehicle related parameters. Due to competitive nature of the market and with the introduction of connected vehicles, the vehicle manufacturers are providing the cluster loaded with many features, thus increasing the price of the vehicle. The increased price may not have effect on customers who actually look out for the features present in the vehicle. But for the customers who does not require the additional features, the price of the vehicle may have an impact in their decision for buying the vehicle. So, the customer may not be interested in buying a vehicle having features that are of no use to a particular group of people.
[0002] Apart from this, due to constant evolvement of technology, the vehicles which seems to have all the features during the time of purchase, can become outdated after a short span of time. But the customer cannot buy an updated version of the vehicle, each time an update is available. Also, whenever, an update is available, the manufacturers cannot update each and every vehicle they have sold or they are already manufacturing. This may increase the development time and cost spent on updating the instrument cluster of various segments of the vehicle. Also, putting all the new features in a single device makes the device complex and the customer may find it difficult to use, while driving the vehicle, or may even get confused what features to be used at what time. In addition to this, in a single display, viewing all necessary features at a same time is not possible. Accommodating two display devices is very easy in a four wheeled vehicle which has a lot of space and can be placed in a closed environment. However, same thing cannot be done in the two-wheeled vehicle. In the two-wheeled vehicle, there is a space constraint for adding another device, so placing a second display where the rider of the vehicle can easily access and view the parameters displayed on that display device, without any discomfort.
[0003] Also, if the second display is a removable device, then a housing unit of the second display device accommodating the display do not have any system which can ensure that the user of the vehicle has not left his/her display device on the vehicle unattended. So, there should be a system which reminds the user to carry the display device always whenever the vehicle is left unattended. Thus, there is a need to overcome the above-mentioned problems and other problems of known art.
[0004] An objective of the present subject matter is to provide a removable secondary display device with a warning unit, which facilitates the user to use additional features without removing the essential features from the primary display device at all times while riding, and also intimates the user to carry the display device, whenever an ignition key is switched OFF, thus securing the display device. The present subject matter further aims to help in reducing the price of the vehicle as well as reducing the time and cost spent for updating the various speedometers. Also, the present removable display device can be customized according to the requirement and expense that the user needs. The present subject matter is described using an exemplary two-wheeled vehicle, whereas the claimed subject matter can be used in any other vehicle, with required changes and without deviating from the scope of invention. The embodiments of the present invention will now be described in detail with reference to a two-wheeled vehicle along with the accompanying drawings. However, the present invention is not limited to the present embodiments. The present subject matter is further described with reference to accompanying figures. It should be noted that the description and figures merely illustrate principles of the present subject matter. Various arrangements may be devised that, although not explicitly described or shown herein, encompass the principles of the present subject matter.
