DE19700066A1 - Switching e.g. motor vehicle engine off and on for brief stops in traffic - Google Patents

Abstract

The on/off switching of the main drive results with a key or a switch, located at the switching lever head, using the fingers of the hand for switching. The electric installation, of the switch or the key with the ignition system, results complemented by the conventional ignition lock-key system. Switching on of the main drive e.g. the engine, conventionally is carried out through the ignition lock-key being in the starting position during a short stop, by operating the key, or the switch, to carry out the starting function. The main drive is conventionally switched off, through the ignition lock with the key turned back, during a short stop, by operating the key, or the switch, which switches off the key function corresp. to the main drive.

Description

Current state of the art:

In the recent past, the automobile has been used both in economical and in ecological improvements made various improvements. From low consumption figures, Exhaust gas cleaning systems, fuel cut-off systems, complete recycling Vehicles has done a lot.

Nevertheless, especially in the metropolitan areas, you are increasingly reaching the limits of the Reasonable. Due to the increasing traffic density in many cities there is often only one tough "stop and go" traffic possible. The resulting noise and Exhaust emissions, with all of their consequences, are a major problem for us Society!

A closer look reveals that a large part of these emissions come from before red Traffic lights waiting or standing in a traffic jam, d. H. not needing effective performance Vehicles.

The question now arises, why do we drivers, despite the emissions, the unnecessary Fuel consumption, appeals from various environmental associations and early training when acquiring a license, "let the engine run"?

Our behavior is certainly not because we do not care about the environment, we are not economical or are lazy!

In my opinion, the cause does not lie in an ergonomic point of view ideal arrangement and also wrong control elements, which for quick removal and Switching on are not suitable!  

Analytical consideration of a switch-on (starting process) and starting process after a service life, e.g. B. switching a traffic light

The engine is off and the traffic light switches!

• 1. slightly bend forward and feel the key;
• - In most vehicles, the ignition lock is not in the driver's field of vision, but rather is covered by the steering wheel,
• - The position of the ignition lock is outside the physiologically favorable gripping space.
• 2. engage clutch;
• 3. Grab the key and turn it to the starting position until the engine is running;
• - The key usually hangs on a keychain with a variety of others Keys, talismans and other attachments that make it difficult to turn,
• - To a sufficiently large moment to turn the key to the starting position the key must first be turned back;
• - From an ergonomic point of view, a key is not an ideal control element which is used for constant actuation is suitable.
• 4. Let go of the key and insert the gear.
• - After ignition, the gear must be engaged with a quick grip on the gear lever will.
• 5. Let the clutch come and accelerate;
• - Vehicle starts to move.

All of these steps must be carried out quickly and without complications as the switched traffic lights and especially the following vehicles an immediate driving on require.

Certainly every driver has his formative memories here whether this is too short Holding the key in the ignition position, accelerating too little, inserting the wrong one Ganges and consequent repetition of the process is one's own excitement and the Expressions of displeasure among the other road users were the result.

The overrun fuel cutoffs on the market have not proven themselves since the Motorists want to decide for themselves on switching the engine on and off.

This leads to the fact that in the future the engine would rather be run.  

My solution to the above problem

Through a simple ergonomic redesign, one can with such short stops achieve significant improvement.

Turning the ignition key to the starting position is activated by pressing a Button switch on the gear lever head replaced! It is also switched off via this Push button switch.

To clarify the advantages, the analysis of the switching on and off process with the repeated new system.

The engine is off, the ignition key is in the ignition position, and the traffic light switches!

• 1. The right hand goes to the gear lever - the clutch is actuated with the foot.
• 2. The gear is engaged and, with your finger, the one on the gear lever head Push button switch pressed until the engine is running,
• 3. Let the clutch come and accelerate,
• - the vehicle starts to move.

The motor is also switched off briefly using this button switch.

Resume

This arrangement eliminates the numerous work steps and all that remains is that Actuation of the push button on the shift lever, which in connection with the necessary Switching process can be seen.

Such a drastic simplification is sure to turn off the Motors at short stops and thus to the advantage of all directly or indirectly involved!

The integration of such a push button switch in a vehicle ignition circuit (regardless of whether Otto, diesel or other type of drive) is neither technically nor financially with great effort connected.

Claims (1)

Switching the main drive on and off for short stops should be quick, safe and easy, this is characterized in that there is a button or switch on the gear lever head. This button or switch is actuated with the fingers of the hand used for switching.
The electrical installation of the switch or button with the ignition system takes place in addition to the conventional ignition lock - key system.
Switching on the main drive conventionally:

• - via ignition lock - key in starting position,
  Short stops:
• - by pressing the button or switch that performs the starting function.
  Switching off the main drive conventionally:
• - Using the ignition lock - turn the key back,
  Short stops:
• - by pressing the button or switch that switches off the main drive according to the key function.
