Abstract

A vehicle fuel economy system that reduces up to 30% of fuel used on a typical journey by regulating power from the engine to the transmission system by using a clutch that is controlled by a speed pedal or speed regulator. The system negates the need for a separate clutch pedal as the connection and operation will be attained by either mechanical or electrical means on activation of the speed pedal/control.

Description

Name of Invention: Vehicle fuel economy through the use of a combined speed and clutch pedal connected by electrical or mechanical means.
Description
This invention relates to the way in which conventional vehicles using an internal combustion engine or an electric engine can improve their fuel or energy efficiency by managing or regulating the way in which power is transferred from its engine to the transmission system using the clutch.
Conventional vehicles transfer power from their engine to the transmission system (manual or automatic), using a clutch. Once the clutch is engaged and a forward or reverse gear selected on the transmission system, power from the engine is transferred to the transmission system and in turn to the wheels via a drive shaft.
By pressing down or depressing the speed pedal or speed control mechanism, power from the vehicle's engine can be regulated into the transmission system to obtain the desired travelling speed of the vehicle.
When a vehicle is travelling (i.e. gear selected on the transmission system and the clutch is engaged), power from the engine is being transferred to the transmission system. In this state the engine will continue to provide power to the transmission system at the rate regulated by the speed pedal or speed control mechanism.
Even when power is not being requested by the speed pedal (i.e. foot taken off the speed pedal) or requested by the speed control mechanism (cruise control, manual button etc.), the transmission system will continue to draw power from the engine at a high rate requiring fuel to be consumed at a higher rate while the vehicle gradually slows down.
The only time the transmission system does not draw power from the engine when it's running even when the speed pedal is pressed down, is when the transmission system in the neutral gear position or when the clutch is disengaged (i.e. clutch pedal is depressed thereby removing power transfer from the engine to the transmission system). In these two states, when the speed pedal is not pressed down, the engine power reduces to an idle or idling state requiring fuel to be consumed at a much lower rate.
This invention reduces fuel consumption of a vehicle by disengaging or removing power from the engine to the transmission system via the clutch when power is not being requested through the speed pedal or the speed control mechanism. Power is only provided to the transmission system when it is requested via the speed pedal or speed control mechanism. Upon request for power or additional power via the speed pedal or speed control mechanism, the clutch then reengages to transfer power from the engine to the transmission system.
Gears can only be selected on the transmission system when the clutch is not engaged (i.e. no power is being requested by the speed pedal or speed control mechanism). When the engine is switched off the clutch is engaged and the transmission system remains in the gear selected prior to the vehicle being switched off. Claim
