FIELD OF INVENTION

The invention generally relates to the illumination system of a motor vehicle and more particularly to a control system used for regulated operation of said illumination system.

BACKGROUND

Generally, vehicle illumination units such as head lamp are controlled by mechanical switches. With the help of said mechanical switches driver switches on the lamp, which in general practice is turned off by switching off the ignition i.e. the engine. On again turning on the ignition key and cranking the engine, the head lamp starts on its on which reduces the battery life and also increases fuel consumption.
Thus a mechanism is required so that the automatic turn on situation of such illumination units can be avoided.

SUMMARY

The present invention provides a control mechanism for illumination system of a vehicle. This control mechanism has an electrical supply system, a pulse generator used to generate a pulse signal on intervention of an activation switch. Further, this control system has a speed sensor (hereinafter RPM sensor) unit secured over an engine and is used to sense speed of said engine.

A microcontroller unit is used in claimed system for generating an activation signal based upon a predefined collective input from mentioned pulse generator and RPM sensor unit. A switching unit is configured to receive input from microcontroller unit and a load cluster to be operated based upon activation of said switching unit.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention will become more fully understood from the detailed description given herein below and the accompanying drawing which is incorporated in and constitute embodiments of the invention, illustrate several aspects of the invention and together with a description of the embodiments serve to explain the principles of the invention and thus, are not limited of the present invention and a brief description of the drawing is as follows:

Figure 1 is an exemplary representation of the essential embodiments of the invention.

Figure 2 is a schematic representation of the enablement steps of the claimed invention.

DETAILED DESCRIPTION

The embodiments disclosed below are not intended to be exhaustive or to limit the invention to the precise forms disclosed in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in the art may utilize their teachings.

The invention may have application to all types of vehicles. The scope of the invention is entirely based upon the claims provided.

Reference is made to Figure 1, which illustrates a block diagram of the essential embodiments of the invention. The illumination load cluster (600) e.g. head lamp/position lamp (601/602) is connected to a switching unit (500) e.g. relay which gets activated based upon the input activation signal, received from the micro-controller (300) connected to it.

Said micro-controller (300) is further providing the outputs based upon the inputs coming from the RPM (revolution per minute) sensor (400) located on the engine (not shown in figure) and the electronic pulse generator (200). Said electronic pulse generator (200) is generating an activation pulse with the intervention of the activation switch (201) which is to be operated manually.

As soon as the activation switch (201) is pressed, electrical circuit of the activation switch (201) with the electrical power supply (100/700) is completed and hence the circuit between the two terminals (100/700) of the battery is completed.

Further referring to Figure 2, enablement steps of the claimed invention are described. Mentioned micro-controller (300) generates (003) an activation signal based upon a specific combination of inputs (002) received from the rprn sensor (400) and the pulse generator (200).

For example, is the engine rprn is greater than or equal to 800 at a high or positive pulse from the pulse generator then the micro-controller will generate an activation signal (003) which will energize (004) the relay (500) to switch on the illumination cluster (600) i.e. the load.

Above described control system thus enables the automatic reset of illumination lamp and ensures that the lamp doesn't turn on without human intervention. Claimed control mechanism for illumination system of the vehicle ensures improved efficiency and longer battery life of the vehicle.
