Abstract

This invention pertains to an economical method of easy conversion of any internal combustion fueled vehicle into a fuel saving hybrid electric vehicle (HEV) by an add-on kit, without replacing the engine and with a minimal modification of the vehicle body. The converted vehicle has a substantially longer driving range on the same amount of fuel than the vehicle before this conversion.

Claims

1. A method of conversion of internal combustion vehicle into a fuel saving hybrid electric vehicle, comprising the steps of:

providing a steerable front wheel(s) driven internal fuel combustion vehicle, which vehicle includes a multi-piston engine with an ignition system and a fuel, a storage space, and non-driven rear wheel(s),

providing at least one electric wheel-motor/generator,

replacing said rear non-driven wheel(s) with said electric wheel-motor/generator(s),

providing at least one electric energy storage unit,

placing and mounting said electric energy storage unit(s) into said storage space,

providing at least one electric control unit for said electric wheel-motor/generator(s),

placing and mounting said electric control unit(s) into said storage space, electrically connecting said electric storage unit(s) with said electric control unit(s) via said electric control unit(s),

providing electric vehicle speed, engine torque, and acceleration sensors,

providing vehicle operator'"'"'s electric command controls,

mounting said sensors and said command controls into said vehicle,

disconnecting said ignition system and said fuel, to at least one piston of said multi-piston engine,

and programming said electric control unit(s) to disconnect said electric motor(s) when a preset cruising vehicle speed and preset low engine torque is reached.

4. A method of conversion of internal combustion vehicle into a fuel saving hybrid electric vehicle, as described in claim 1, or 2, or 3, in which said electric control units are included in said electric wheel-motor/generator(s).

5. A method of conversion of internal combustion vehicle into a fuel saving hybrid electric vehicle, as described in claim 1, or 2, or 3, in which said electric control units compensate for driving different revolutions per minute of said wheel-motor/generator(s) during turns of the vehicle.

6. A method of conversion of internal combustion vehicle into a fuel saving hybrid electric vehicle, as described in claim 1, or 2, or 3, in which said electric drive sensors and command controls communicate with said vehicles combustion engine controls and drive system sensors.

7. A method of conversion of internal combustion vehicle into a fuel saving hybrid electric vehicle, as described in claim 1, or 2, or 3, in which said electric energy storage unit comprise a battery and ultra-capacitor.

8. A method of conversion of internal combustion vehicle into a fuel saving hybrid electric vehicle, as described in claim 1, or 2, or 3, in which said electric energy storage unit is a battery.

providing electric vehicle speed, engine torque, and acceleration sensors,

providing vehicle operator'"'"'s electric command controls,

mounting said sensors and said command controls into said vehicle,

disconnecting said ignition system, and said fuel to at least one piston of said multi-piston engine,

and programming said electric control unit(s) to disconnect said electric motor(s) when a preset cruising vehicle speed and preset low engine torque is reached.

3. A method of conversion of internal combustion vehicle into a fuel saving hybrid electric vehicle comprising the steps of:

providing a steerable all wheels driven internal fuel combustion vehicle, which vehicle includes a multi-piston engine with an ignition system and a fuel, and a storage space,
