A Display System for a Vehicle

APPLICANT
TVS MOTOR COMPANY LIMITED, an Indian company, having its address at “Chaitanya”, No.12 Khader Nawaz Khan Road, Nungambakkam, Chennai 600 006, Tamil Nadu, India.

PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed. 
FIELD OF THE INVENTION
[001] The present invention generally relates to a display system. More particularly, the present invention relates to a display system for a vehicle.

BACKGROUND OF THE INVENTION
[002] With the overall advancement of vehicles, usage of a heads up display is becoming more prominent. A head-up display, or heads-up display, also known as an HUD, is any transparent display that presents data without requiring users to look away from their usual viewpoints. In an HUD, the rider is able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instrument panel.
[003] In one of the conventional heads up displays for vehicles, a virtual image is formed on the road from drivers' point of view with the help of heads-up display concept. However, the device used for the heads-up display needs to be separately attached as an add-on and is then integrated with other components in the vehicle using individual communications. In other conventional heads up displays for vehicles, an augmented image is formed on the road to assist the rider to follow navigation using heads-up display concept. However, in this heads-up display system similar to other conventional systems, the device used for the heads-up display needs to be separately attached as an add-on and is then integrated with other components in the vehicle using individual communications.
[004] Similarly, most conventional heads-up display systems are available as an external accessory and need to be retrofitted to the vehicle. Existing architecture of the vehicles in the market has lower flexibility to include the heads-up display. Particularly, in case of two-wheelers, the heads-up display implementation remains a challenge, because packaging an additional unit near the headlamp housing increases the complexity in the assembly.
[005] Further, the electronics used for the heads-up display additionally increases the cost of the system because separate controllers need to be added to heads-up display unit for processing the data & communication with the other nodes. Additionally, for existing systems, the form factor is as high as twice of the existing instrument clusters, which make the packaging of heads up displays in case of the two wheeler environment a further challenge.
[006] In terms of the software, the design side which handles the data segregation is complex in the existing systems. The data segregation is required to manage the data between the multiple controllers to provide relevant data to the user by sharing the portion of the display data between the instrument cluster & heads up display unit.
[007] Thus, there is a need in the art for a display system for a vehicle, which addresses at least the aforementioned problems.
