DESC:FORM 2 The Patent Act 1970 (39 of 1970) & The Patent Rules, 2005 PROVISIONAL COMPLETE SPECIFICATION (SEE SECTION 10 AND RULE 13) TITLE OF THE INVENTION “Method and system for determining coasting distance for a vehicle” APPLICANTS: Name Nationality Address Mahindra & Mahindra Limited Indian Mahindra & Mahindra Ltd., MRV, Mahindra World City (MWC), Plot No. 41/1, Anjur Post, Chengalpattu, Kanchipuram District – 603204 (TN) INDIA The following specification particularly describes and ascertains the nature of this invention and the manner in which it is to be performed:- FIELD OF INVENTION This invention relates to vehicles and more particularly to enabling a driver to manage driving of a vehicle. BACKGROUND OF INVENTION Coasting a vehicle refers to driving the vehicle, when the vehicle is in neutral gear and the accelerator pedal or the brake pedal are not being pressed. The driver can also have the clutch fully depressed or partially depressed, when the vehicle is coasting. The car can remain in motion when the car is coasting, till the vehicle completely loses momentum and comes to a halt on its own or the driver of the vehicle applies an input such as a brake pedal. The driver can also exit coasting, by pressing the accelerator pedal. Coasting can be done, when the vehicle is on a downward slope, coming to a signal/stop sign or any other cause, which will cause the vehicle to halt, maintain a steady speed or slow down gradually. It is claimed that coasting can provide benefits, such as improved fuel efficiency, a reduction in emissions from the vehicle (such as CO2, NO2 and so on), a reduction in the carbon footprint of the vehicle and so on. Even though, coasting provides benefits, the driver typically has to judge the feasibility of coasting, coasting distance possible to the vehicle and so on, based on his experience. In most cases, the driver will opt not to coast, even when the driver has to the option to coast the vehicle. This can result in the vehicle and the driver of the vehicle, being unable to avail benefits offered by coasting. OBJECT OF INVENTION The principal object of this invention is to propose a method and system for determining the coasting distance available to a vehicle, based on a plurality of parameters such as the current state of the vehicle, at least one parameter related to the vehicle and so on. Another object of the invention is to provide a method and system for providing an indication to the user about coasting distance available to a driver in a plurality of scenarios.

DETAILED DESCRIPTION OF INVENTION The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein. The embodiments herein disclose a method and system for determining the coasting distance available for a vehicle. Referring now to the drawings, and more particularly to FIGS. 1 through 8, where similar reference characters denote corresponding features consistently throughout the figures, there are shown preferred embodiments. FIG. 1 depicts a vehicle moving along a road, according to embodiments as disclosed herein. The vehicle can be any vehicle, which can be used on a road. Examples of a vehicle can be a car, a motorbike, a scooter, a van, a bus, truck, or any other equivalent means of transport, which can use a road for movement. The term ‘road’ as used herein can refer to any path, which enables movement of vehicle along its surface. The surface of the road can be a smooth surface or a rough surface. The surface of the road can comprise of tar, concrete, tiling structures, sand, stones, paving stones, or any other equivalent means. The road can comprise of at least one obstacle, which can make the vehicle to stop or slow down. FIGs. 2a, 2b and 2c depict example scenarios which cause a vehicle to slow down from a higher speed or maintain a speed for a certain amount of time. In FIG. 2a, the vehicle is approaching a signal which is red for the direction in which the vehicle is approaching. In FIG. 2b, the vehicle is on a downslope, which causes in the vehicle increasing its speed automatically, as the vehicle moves down. IN FIG. 2c, the vehicle is travelling on a long straight stretch of road where the vehicle can maintain a steady speed. The above depicted scenarios are examples and embodiments herein can be extended to other scenarios where the vehicle can move without the driver needing to press the accelerator or brake pedals. FIG. 3 depicts a system for estimating the coasting distance for a vehicle, according to embodiments as disclosed herein. The system, as depicted, comprises of a Coasting Estimation Module (CEM) 301. The CEM 301 can be connected to at least one memory 302. The memory 302 can comprise of a plurality of parameters related to the vehicle such as the unladed mass of the vehicle 101, laden mass of the vehicle 101, parameters related to the wheels and tyres of the vehicle (such as footprint of the tyre, radius of the wheel/tyre, and so on), which wheels are the driving wheels and the non-driving vehicles (which can be changed automatically or by a driver of the vehicle) and so on. The CEM 301 can be connected to at least one other system and/or component present in the vehicle 101, such as the engine, clutch box, the accelerator pedal, the brake pedal, the axles, and so on, to collect real-time and instantaneous information about the vehicle. The CEM 301 can also be connected to a component which can provide details about the current state of the vehicle, such as the ECU (Electronic Control Unit) of the vehicle and so on. The CEM 301 can be connected to at least one display 303. The display 303 can be at least one of the dashboard of the vehicle, the instrument cluster of the vehicle, a Multi-function display means in the vehicle (in the instrument cluster and/or the dashboard), a device connected to the vehicle 101 using a suitable means (such as WiFi Direct, Bluetooth, wired means (USB (Universal Serial Bus), auxiliary cable, audio jack, and so on) and so on), the infotainment system of the vehicle, a display screen in the vehicle, a Heads-up-Display (HUD) in the vehicle and so on. The CEM 301 can be configured to estimate the distance that a vehicle 101 can coast; i.e., the distance that the vehicle 101 can move if the driver of the vehicle releases the accelerator pedal of the vehicle 101 at that instant. Consider that the vehicle is currently moving at velocity v_current. Consider that the final velocity is v, wherein v
