FIELD OF THE INVENTION

The invention generally relates to an electric load control system for a motor vehicle and more particularly to an electric load control system enabling the controlled power supply from the power generation unit making the vehicle more efficient.

BACKGROUND OF INVENTION

Generally, in motor vehicles electrical load requirement can be different depending upon the usage of the vehicle and type of the vehicle e.g. load requirement during the day and during night will be different as electric elements used are more, also for a more powerful motorcycle such as sports sector motorcycle electrical load will be more specially while on high speed and will be lesser in normal day conditions.

In the present technology power supplied from the power generation unit to the electrical load is constant and hence in case of lesser requirement, remaining power is not used and hence power loss is more.

Thus there is a need of a system which can address above mentioned issue of power loss and can manage the input of power to the required electrical load of the vehicle.

SUMMARY OF THE INVENTION

The present invention provides a motor vehicle having an electrical load control system, which improves the efficiency of the vehicles. Said electrical load control system has a power generation unit, a rectification assembly with multiple rectifying elements, configured to rectify input from the power generation unit, a regulator assembly having multiple regulating elements configured to regulate input from the rectification unit, a sensor element configured to sense power requirement on a load cluster and a control unit configured to receive signal from the sensor element and generate signal for the rectification assembly.

Said rectification assembly and the regulator assembly are configured to produce power output in synchronization with output of the control unit, so that the power supplied towards the electrical load can be supplied as per the requirement, resulting in the improvement of efficiency of the vehicle.

Figure 1 is the block diagram of the essential embodiments of the claimed invention.

Figure 2 is showing an exemplary arrangement for the claimed invention.

DETAILED DESCRIPTION OF THE INVENTION

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 required embodiments of the claimed invention. The claimed electrical load control system can have variable load requirements (700, 800) depending upon the usage of the vehicle e.g. day time usage or night time usage. Thus the power requirement for the electrical load (700, 800) keeps on changing.

To regulate incoming power from the power generation unit (100) a control unit (400) is used through a regulator assembly (300). Said regulator assembly (300) sends output to a rectification assembly (200) which rectifies the required power for the active load (600/700/800).

Said control unit (400) gets activated after receiving signal from the load sensor (500) which is working on the principle of current sensing. Said control unit (400) receives said signal from load sensor (500) in voltage form and then a voltage to frequency convertor (402) generates a frequency signal, with that voltage input, for the microprocessor (401) and said microprocessor (401) generates regulating signal for the rectification unit (200) having multiple rectifying elements (201).

Said rectification unit (200) further rectifies the output of the power generation unit (100) and send it to the regulation unit (300) and hence the load cluster (600/700/800) receives the required power.

Supply of limited and calculated power to the load cluster saves generated power which can be used in the transmission of the vehicle which results in a greater efficiency of the engine and hence the performance of the vehicle improves.

The mentioned load cluster (600/700/800) can include battery charging (600), day time electrical load requirement (700/800) or night time load requirement (700/800) or any other kind of electrical load requirement.

As shown in Figure 2, load cluster (600/700/800) includes battery charging (600), different illumination lamps (703, 704, 802, 803, and 804) and other electrical devices such as horn (801), starter relays (701) and starter motor (702) etc. By minimizing electrical loads (700/800), power requirement for the electrical loads (700/800) can be reduced and usage of low power illumination units such as LED based illumination lamps is one of the good examples for load reduction.

With a constant power generation unit (100) efficiency of the vehicle can be improved by supplying more power to the mechanical functioning as soon as the requirement of power for reduced electrical load is less.

Further, electrical power requirement keeps on changing as per the usage of the vehicle e.g. day time requirement or night time requirement as more illumination units are required for the night time usage. For example, during day time illumination lamps such as head lamp (703) is not required.

Also, illumination lamps such as tail lamp (704), stop lamp (802), turn signal lamp (803), and position lamp (804) are not required constantly thus electrical power requirement may vary even while driving the vehicle. Present circuit is providing the facility for the sensing the power requirement for the electrical load (600/700/800) and thus the claimed system supplies only required power to the load cluster (600/700/800) which results in more power availability for mechanical functions hence the efficiency of the vehicle improves considerably.

Following comparison Table 1 is an example of the varying power requirement of the electrical load and its relation with the total generated power. This comparison is based on the partial throttle condition.

As shown in Table1, electrical power requirement reduces as per the driving condition thus constant power supply to electrical load cluster, when not required leads to wastage of the power whereas excess power can be utilized for different application. Claimed system senses the load requirement and based on that control unit (400) controls the power supply to the load cluster (600/700/800).
