DE3430173A1 - Circuit for indicating the intention to brake - Google Patents

Abstract

The essential part of the invention is the constructional arrangement and vehicle-dependent attachment of the microswitch A, the position of rest of the throttle linkage C closing the make contact G and the working position of the throttle linkage c closing the normally closed contact H. In this arrangement, it is completely irrelevant from which point of the throttle linkage C/c the control lever E/e is actuated. The invention described has the advantage of triggering, by the installation of a microswitch at a suitable point in the motor vehicle, light signals which indicate the intention to brake to drivers of motor vehicles behind. The driver of the motor vehicle behind now has the possibility of reacting much earlier than before to a braking process of the driver of a motor vehicle in front. He is thus prepared earlier for the braking process and, as a result, can avoid accidents. <IMAGE>

Description

13 braking intent indicator circuit on motor vehicles

The invention relates to a switching device and signal display for Early detection of an intended braking process in motor vehicles.

5 is known that the braking process in motor vehicles by at the IIeck Attached brake lights is displayed 0 this circuit is initiated Braking process displayed.

Only when the brake pedal is depressed is a switch activated Brake light activated.

The following driver only now has the opportunity to react. The many rear-end collisions clearly marked this deficiency.

The object of the invention is to propose a switching device, which makes it possible, at a low cost price, through switched signal lamps the colors yellow and green, definitely and clearly a much earlier information to give to the following driver. Because the driver recognizes in time and can react, a high percentage of all rear-end collisions are avoided.

The task is solved by installing a microswitch A.

The switch is located near the throttle linkage C with a suitable Sheet metal strip B attached to the body.

The same is arranged so that the lever E of the microswitch A is depressed by the dormant accelerator pedal D.

The normally open contact G is closed and the one via a suitable one The yellow lamp connected to the line lights up.

See Figure 1.) If the accelerator pedal is pressed, it opens automatically the normally open contact G and the normally closed contact H turn on a green lamp. Please refer Figure 2.) Foot off the gas then means - attention yellow light, it could be braked -.

Foot on the accelerator pedal D means - green light, there is no braking expected.

The provided microswitch A has the advantage that there is no switching delay occurs so that either yellow or green are always switched.

The lamps are connected to a suitable cable, which is installed in the interior of the Motor vehicle is relocated, connected to the microswitch A. The tension you need at contact F, since the consumption is very low, there can be one to be determined Backup can be tapped.

The following driver can, as he is the driving behavior of his Can recognize the person in front, adjust in good time for a possible braking process.

The more important seconds are more likely, seconds more bring readiness to brake and thus gain important nests that help avoid accidents.

r can also rely on the fact that if the foot of the person in front is on the accelerator pedal, a green lamp indicates this. A sudden one braking without a yellow light display is therefore inevitably not possible.

The yellow light indicator remains on until either the ignition key is removed or the right foot depresses the accelerator pedal again and thus switched to green zf Lrd It is planned, for the time being, the lamp arrangement -green / yellow to be installed in a suitable housing.

In the case of a car, the housing can be attached to the rear shelf, for example. The lamps are then clearly visible from behind through the rear window.

A Rombi wagon is attached to the window of the leak flap thought.

The lamps can also be used on the rear of trucks and trailers be attached.

The circuit described has the advantage of being much earlier than so far to recognize a braking process of the vehicle in front.

The intention to brake is displayed here much earlier the following driver adjust to the driving style of the person in front.

Zr is ready to brake earlier and can cause accidents avoid.

Claims (4)

Patent and claims for protection 1.) Switching and display device for Early detection of the intention of a motor vehicle driver to initiate a braking process. 2.) One in motor vehicles, by gas or injection rods, or Gas or injection cable with the help of a mechanically operated micro switch, evoked control of a traffic light system. 3.)
