PATENT APPLICATION

Device for improving the braking systems of automobiles

PATENT APPLICATION

Device for improving the braking systems of automobiles

The invention relates to a device for reducing the reaction time of the driver in the face of a sudden dangerous situation. This device also enables the driver to automatically apply the brakes and bring the vehicle to a standstill as quickly as possible if any reaction by the driver to an obstacle fails.

The centerpiece of every automotive brake system is the master brake cylinder. He divides the system into 2 areas: 1. The opto-sensory part i.e. the delays deliberately initiated and controlled by the driver.

2. The automatic part i.e. the automatic deceleration. This area has been improved in recent years by a rapid, not yet completed technical development: ABS, disc brakes, general application of electronics, tire optimization, etc. These improvements ensure that a vehicle remains directionally stable and steerable when braking on slippery roads. However, they do not provide the hoped-for braking distance reduction.

As is known, the braking distance is only part of the stopping distance (which is important). Then there is the reaction path.

This reaction path is determined by the reaction time of the driver (from the detection of an obstacle to the> actuation of the brake pedal.) P /

This time is not constant, it may last depending on personal conditions. external circumstances of 0.3-1.7 sk, on average, theoretically 1 sk (frightening second).

The brake pedal as the central transition from the driver to the brake mechanism also proves to be a significant deceleration factor when braking. The reason for this is the anachronistic arrangement of gas u. Brake pedal. This arrangement requires a u.

· Very different movements on the same foot: lifting,

Move, push, and in an ergonomically wrong order. The result is, in association with the right side by pressure, kink u. Cramped states of the driver's nerve strains, an often fatal delay in the initiation of braking. (Is the devil there?)

Another weak point in automotive technology is the lack of an automatically operating shock switch that affects the brake system. In the event of a collision on one side or at an angle, the driver may be pushed out of his normal sitting position and the brake pedal is no longer accessible, or the driver may have been unable to operate it.

The car then continues to slide unchecked until it comes to a standstill, often with catastrophic consequences for the car occupants.

Preventing such a wild run of a vehicle is the purpose of the push switch, which is well known per se. An application example of such a shock switch, as well as the above-mentioned device for reducing the driver's reaction time, can be seen from the attached drawing and Blocl * circuit diagram. p ^ - 3 -

Starting from the car battery (1), an electrical line brings direct current to a potentiometer (2) attached to the steering wheel. This potentiometer is manually operated by the driver (thumb brake) and activates a solenoid valve group (4), consisting of a logistically assembled combination of individual valves that gradually and sensitively discharge the oil from a high-pressure oil reservoir (7), depending on the intensity of the thumb pressure from the driver to the potentiometer , regulated ;. The oil pressure is then, according to the design of the brake system, ί-direct to the main brake cylinder (9) or to an ABS unit. ’(Ti / guided, · and the 'deceleration is initiated /: analogous to the process' with pedal operation.;',

It should be noted that this braking should only take place in an emergency. Their intensity remains at the discretion of the necessary AîAalteWëgea ·· by dfeniFahrer.K: i · rer.

m • „4 ¥ - é- 1. Device for improving the brake systems of automobiles, consisting of a potentiometer (2) attached to the steering wheel, which is operated manually by the driver and the like. A solenoid valve group (4) at the outlet of a high-pressure oil reservoir is activated by electric wire, bypassing the pedal brake. This solenoid valve group initiates the braking u. stop until the desired deceleration of the automobile is reached. ; 2. An appropriate one. Shock switch Imports an electric shock directly to the solenoid valve group 1 (4) after the automobile hits an obstacle. The 'delay is thus initiated automatically'. stops until the automobile comes to a standstill or until the switch is manually unblocked by the driver. / «« Β *
