FIELD OF INVENTION

The present invention relates to battery less motor vehicle and more particularly to the electrical load control system for a battery less motor vehicle.

BACKGROUND OF THE INVENTION

Generally, in conventional battery-less vehicle starting of the engine is difficult as by kick method generated power is very less and if any other electrical load of the vehicle is in ON condition then generated power gets distributed and hence the generator is unable to supply a minimum power which is required for the operation of the igniter. Thus, to ensure smooth start, electrical load supply for the vehicle is required to be controlled.

European application holding number 0646723A1 discloses a solution for the above problem by having a controller to activating the igniter with the rotational output characterized in that the supply of power to electrical loads is stopped until the engine is brought to a predetermined engine speed upon its start up. The said controller controls the loads of the vehicle based on the output of the engine speed sensor or crank angle sensor.
Implementation of above mentioned solution to the problem has a drawback in terms of the cost as the engine speed sensor and the use of controlled in correlation with the sensor is not cost effective. Thus a cost effective way to ensure a easy and smooth kick start of the engine in battery less vehicle is required.

SUMMARY OF THE INVENTION

The present invention is related to an electrical load control system for a battery less motorized vehicle with multiple AC generation units supplying current to an ignition control unit and an electrical load control unit such that input to the electrical load control unit is passing through a regulatory unit. Said electrical load control unit has multiple voltage generators and a voltage comparator unit transmitting signal to a switch control unit based upon voltage level difference of the voltage generators resulting in electrical load regulation of the vehicle through multiple switching units.

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 motorized vehicles.

Figure 1 is the schematic diagram of the invention showing the essential embodiments of the invention. AC generation unit 1(101) and AC generation unit 2 (102) are supplying input to the ignition system as well as to the vehicle electrical loads. AC generation unit 2 (102) is acting as a pulse supplier as sending pulses to the ignition control unit (103) to ensure supply of the minimum power, which is required for the operation of the ignition coil (104) to produce the spark through the spark plug (105).

Further, the AC generation unit 1 (101) is supplying AC input to the regulatory unit (106) that is further distributing its output between ignition control unit (103) and electrical load control unit (112). Said electrical load control unit (112) is controlling the operations of the electrical loads (hereinafter electrical load cluster) (100) of the vehicle.

Said electrical load control unit (112) receives input from regulatory unit (106) wherein said input is divided among multiple sub elements such as voltage generator 1 (108), voltage generator 2 (107), voltage comparator (109) and the switch units (111). Voltage generators 1 and 2 (108 and 107) generates different voltages based on the input provided and thereupon the voltage comparator (109) compares the voltage of voltage generator 1 (108) and voltage generator 2 (107) and when the predetermined condition, for example voltage of generator 2 (108) <= voltage of generator 1 (107), of the voltage comparator (109) qualifies then a signal from the voltage comparator unit (109) goes to the switch control unit (110) and in turn said switch control unit (110) supplies input to the switch units (111) for operation. Predetermined condition for the voltage comparator (109) can be different for different type of voltage generators (107,108) used.

Referring to figure 2, a schematic representation of an exemplary type of the voltage generators (204, 207) and voltage comparator (205) with switch control unit (206) is shown in order to explain the predetermined condition of the voltage comparator (205) for release of the signal to the switch control unit (206).

Electrical load control unit (200) is receiving the input from regulatory unit (203) and said input is divided among voltage generator 1 (204), voltage generator 2 (207), voltage comparator (205) and the switch control unit (206).

Based upon the input received from the regulatory unit (203) voltage generator 1 (204) provides output (V1) in accordance with the value of the resistance (R2, R3) used in series. Further, voltage generator 2 (207) will produce voltage (V2) based upon the fixed value of the zener diode (ZD).

Thereupon, the voltage comparator (205) compares the voltages (V1 and V2) and when V1 > V2 said voltage comparator (205) will send a signal to the switch control unit (206) and said switch control unit (206) will send output to the switch unit (208) in order to operate electrical load cluster (209).

The method and the predetermined condition for the electrical load control unit (200) can change and is subjected to the type of voltage generators (204, 207) and voltage comparator (205) used thus shall not be taken as a limitation for the scope of the invention.
