Abstract

In order to fully understand how the Fuel Stop Safety Switch functions, it is essential for a general understanding of the normal function of the fuel injection system. We start with the driver pressing the accelerator pedal, this sends a command through it'"'"'s throttle positioning sensor to the electronic control unit, which receives signals from various sensors and uses this data to determine the fuel needed to maintain efficient and normal operation of the vehicle. When the brake is applied it will activate the Fuel Stop Safety Switch, which will send a signal to the electronic control unit which will return the engine to the idle position, and will remain at idle position as long as the brake pedal is depressed. This will enable the driver to bring the automobile to a stop regardless of the drivers negligence in not removing his or her foot from the accelerator. This can be achieved in one of two ways, one is to install a Fuel Stop Safety Switch. The second way is to rewire the existing brake switch to send a signal to the electronic control unit.

Claims

1. Will in all probability, help to prevent fatal accidents. It is a known fact, that as a person gets older they are not as mobile as a younger person, this leads to a reduction of mobility. therefore, an older person in time of emergency may have a serious problem. This is not to say that stepping on the brake and accelerator can not happen to anyone of any age in times of emergency. The Fuel Stop Safety Switch will alleviate this problem by eliminating human error in a emergency, allowing and helping the driver to come to a safe stop.

Police Pursuit Advantage of the Fuel Stop Switch

2. The FUEL STOP SAFETY SWITCH can also be used in conjunction with Car Star, On Star, Lojack and all registered trademarks. In this case, the Control Module would receive a signal from a satellite or G P S receiver, this would be the same signal that the vehicle now sends in the case of theft or accident. The signal could be programmed to activate the Control Module to reduce the flow of fuel to the idle position which could be used by the law enforcing authorities to apprehend the perpetrators. This would be especially useful in the case of pursuit, and would without doubt reduce the number of fatalities connected to police pursuit.

Snow or Mud Advantage of the Fuel Stop Safety Switch

3. Another use of the Fuel Stop Safety Switch would be the advantage to the driver in the case of being stuck in mud or snow.

Number #-1 Stepping on the brake pedal which will momentarily limit the fuel being delivered to the motor.

Number #-2 Depressing the accelerator part way.

Number #-3 Releasing the brake pedal.

Repeat steps number #1 #2 #3

This will crate the rocking motion that is needed to free the vehicle.

Faster Starts

4. The same procedure will be followed for a faster start. For a situation where faster then normal acceleration is required;

Number #-1 Press down on the brake pedal.

Number #-2 Apply pressure to the accelerator.

Number #-3 Release the brake pedal.

This procedure is to be utilized only when a quicker then normal acceleration is desired and is not recommended for normal driving.
