Abstract

The idea is that the vehicles move on roads prepared for execution by adjusting their speed and direction according to the actual accident, and in some cases even under the influence of the surroundings. In other words, it is based on the design of an accident participant or expert, as if it existed on the eve of an accident.

In particular, the accident can be reproduced not only in relation to the vehicle and driving class used in that case, but also in the place where the surrounding factors are dominant and special in the context of the accident, that is, on the very specific road where the accident occurred.

In this way all the influences of the accident process are taken into account and the thinking can be reproduced very realistically. Participants' statements are tested in relation to the issue of liability, by comparing the recreated and actual incidents, even in the absence of accurate evidence such as brake wheels caused by the use of ABS. To test the impact of a car accident on a passenger, a model doll is tested in the vehicle as in a crash test. The driver's reactions such as braking, turning, etc. are also reproduced in the context of the accident.

Description

Equipment for testing the effects of car accidents {ELECTRONICALLY CONTROLLED VEHICLE CRASH SYSTEM}

The present invention relates to a device for experimenting the effects of a car accident, and more specifically, to provide a device for measuring the performance of a car by reproducing and simulating a real accident.

A facility for testing the effects of a car accident, in which at least one car is led to a predetermined crash site.

The challenge is to reproduce concrete and real thoughts.

This can be accomplished by operating one or more vehicles on a road that is ready for action to reproduce the accident, adjusting the speed and direction to match the actual accident.

In the automotive industry, new cars are tested in crash tests when molded. In this, the car moves and collides with any obstructions. The obstruction is of course fixed but may also be a moving second vehicle.

Simulated accidents are tailored to the vehicle and dummy in this test, especially those at risk, ie overturning the vehicle. Frequent accidents, mainly known by accident statistics, are simulated, for example, collisions, frontal collisions or kite collisions in which different vehicles are made from different angles.

During and after the simulated accident, the dummy and the impacts and wounds on the vehicle are recorded and used to improve the passenger's active and passive safety. In part, crash tests often use vehicles generated by computer calculations and computer simulations as tests and adjustments.

In the crash test, the vehicles are adjusted by means of remote control and the like. In most cases, passengers are experimented with dummy.

In DE-OS 32 48 192 there is a device that records against crash tests, which records the vehicle's information before the accident and can be installed as an accident recorder in actual accidents, like a black box on an airplane. . Information such as speed, brake operation, horns and direction indicators are recorded and in the event of an accident it must provide guidance such as whether the direction indicator has malfunctioned or the speed is not too high and should be used for accident accountability. do. At any time, information about 200 meters of the latest mileage is recorded, and all information about the distance before 200 meters is erased.

With crash tests and the DE-OS 32 48 192 method or facility, it is impossible to reproduce an accident in consideration of the actual vehicle involved, the speed of the vehicle, the direction of the vehicle, etc. In a crash test, you only run an accident to test the impact on the vehicle. The accidents that actually happened in the traffic accident are not reproduced, but the daily accidents given by the accident statistics are reproduced.

The accident recorder for DE-OS 32 48 192 is not intended for the reproduction of accident conditions. This recorder only provides information about an accident that has already occurred. The experimentation of the various acts on the accident cannot be carried out with this recorder.

Therefore, this conception lies in the following tasks. In other words, the method of experimenting with the effects of the above-mentioned types of car accidents will be further developed so that the actual accidents can be reproduced. In addition, some equipment can be attached, which leads to one or several vehicles corresponding to the accident situation.

This problem can be solved by claim 1 according to the idea.

When implementing the scheme on an idea, one or several vehicles move on the road ready for execution by adjusting the speed and direction according to the actual accident, and in some cases even under the influence of ambient influences.

In implementing the method in line with the idea, the process is reproduced based on the statement of the witness, the participant or the expert, just as it was before the accident, the exact process of the vehicle speed, just like the direction of the vehicle. Accidents are not only reproduced in that case with regard to the vehicle used and the class of travel, but can also be reproduced at the place, i.e. on the very specific road where the accident occurred, if the surrounding factors are dominant and special in the context of the accident.

In this way all the influences of the accident process are taken into account and the thinking can be reproduced very realistically. Participants' statements are tested in relation to the issue of liability, by comparing the recreated and actual incidents, even in the absence of accurate evidence such as brake wheels caused by the use of ABS. To test the impact of a car accident on a passenger, a model doll is tested in the vehicle as in a crash test. The driver's reactions such as braking, turning, etc. are also reproduced in the context of the accident.

In this experiment, a car moves on a road ready for execution, and an induction cable is installed on the road surface or inside the road. Induction cables can be easily and quickly installed on road surfaces. Just before the accident, the car is installed up to the point of accident along the way it was originally and the vehicle to be used for the accident moves along the induction cable to the point of accident. There once everything related to the accident has a magnitude of known vehicle movement and crashes from the accident that can be reproduced.

It is an advantage if the vehicle that reproduces the accident is driven by a motor in the bodywork. In this case, it is effective if the speed of the vehicle is defined by the operating device, for example by a change in power rotational speed. In addition, the speed of the vehicle is changed by the change of the transmission gear ratio in the case of automatic transmission or by the change in power rotation speed in the case of transmission, and the vehicle is adjusted by the operating device and the speed is controlled by the operation of the brake of the vehicle. Slowed down.

In this way all of the vehicle's driving functions and motion parameters can be changed by the influence of the motor, powertrain, direction and brakes. Since the car is then not directly influenced by the outside, but is moved by the facilities in the body, the accident situation can be reproduced very realistically. No additional equipment, such as external operating aids, the vehicle's derailment or forced direction indication to the point of accident is required.

In order to adapt itself to the standard values of the motion parameters as the car proceeds to an accident without significant action from the outside, the actual values of the motion parameters, in particular the speed, the inclination of the steering wheel and the brake operation, are recorded separately or all together by the sensor. It is effective if the standard values given by the actual accident situation are adjusted by the driving control means.

It may also be an advantage if at least part of the motion parameters is controlled by signals outside the vehicle. The signal is then received by the receiver of the bodywork and continuously guided for the adjustment of the parameters in the travel control means. Because the vehicle is somewhat damaged when an accident occurs, the cost of reproducing the accident in this way will be significantly reduced unless additional thinking of expensive control or storage facilities other than the actual sensor and coordination equipment is needed. . In addition, larger and faster calculators can be installed in this case.

This calculator allows for a change in motion parameters over a short period of time, which may prove necessary when viewed from the outside. Communication with the vehicle control means is made via an antenna, for example made of an antenna, installed in the vehicle body.

In order to give each other the best knowledge of the relative position of the vehicle at each point in time while it is being reproduced, and to give one of the actual accidents that corresponds exactly to the vehicle's movement process in relation to the point of accident, In case it can be advantageous.

In other words, if the instantaneous position of one or several vehicles is calculated by a coordinated computer system combined with an induction cable, based on the trigger indications regularly present in the induction cable, then the standard values and actual values of the motion parameters as relative positions If the quantities are to be compared and the corrected value is transmitted to the corresponding travel control means. An induction cable transmitter of any type may be placed between the coordinating computer system and the induction cable.

This is with the aid of an induction cable, which sends the calibration value to the vehicle control means via the receiver of the vehicle mounted on the vehicle body.

Get a thorough insight into motor parameters such as speed and others just before an accident and during the course of an accident, and also provide a model puppet that describes the passenger's position in experiments for possible damage in other measurement sizes-accidents. In order to obtain accurate insights into, for example, whether it was slow or accelerated by means of an accident, if a motion parameter and also a wide range of measurement sizes are accepted and transmitted to the in-vehicle computer system for storage and later use, It is an advantage.

In addition, in order to prevent possible loss of information in the event of an accident, the transfer of information to a computer or storage device external to the vehicle can naturally occur.

The driving computer can be made as an integral component in the vehicle control means. If something unexpected happens, such as a technical defect that obstructs or even prevents the reproduction of an obstacle or accident on the road prepared by the induction cable, It would be an advantage if the emergency braking system would be operated without the adjusting direction or other technical equipment as in the external situation to the contrary.

This can be done manually, such as in the case of technical defects, as in the case of obstructions present on the road.

A more advantageous way of implementing this idea is to lead with the help of a laser beam on the road actually prepared. In addition, conventional lasers can be used, which can be mounted inside or outside of the body.

In both cases, the vehicle is led to the collision site in a way that achieves its purpose. In a laser mounted on a vehicle, for example by means of obstructions, the laser beam is reflected by a different vehicle in some cases with the aid of a mirror, and the reflected laser beam adjusts the vehicle. The laser can likewise be mounted on the outside of the vehicle so that the vehicle will collide along the laser beam.

In order to prevent the laser from being damaged when the vehicle collides, the following cases are effective, in which the laser is attached to the outside of the vehicle and the laser beam is received by the laser receiving equipment attached to the vehicle. Even when the condition of the vehicle with respect to the obstacle is determined, the deviation of the direction of the vehicle and the laser beam can be defined with the aid of the receiving equipment, and the vehicle can be adjusted in consideration of the speed as well.

In this connection, it proves effective when the laser beam receiver is made from a series of photovoltaic plates. In essence, the reception of the laser beam in response to the place is made on the basis of parallel photovoltaic plates and it is easier to travel along the road given by the laser beam.

In that it is effective if the travel control means and the travel computer are coupled to the laser beam receiver separately or together. With the help of the signal transmitted by the laser beam receiver, the driving control means or the traveling computer can define the vehicle out of direction relative to the laser beam and the vehicle travels along a given road. So the vehicle moves to the point of collision quickly and without error.

In contrast to induction cables placed on the road surface or inside the road, the use of a laser system requires no additional work.

If the emergency brake function resolves in such a case where the vehicle misses the laser beam, it is effective. The uncontrollable process of thinking is thus limited.

The following is a closer illustration of this idea in relation to the schematic of the depicted example.

1 is a system diagram of two vehicle collision facilities with an induction cable indicating device of the present invention, FIG. 2 is a system diagram of a vehicle vehicle collision facility with a laser indicating device of the present invention, and FIG. 3 is a laser indication of the present invention. Alternatively, a vehicle collision facility system diagram having an induction cable indicating device is illustrated in FIG. 1, in which two vehicles having one induction cable indicating device are illustrated.

The facility foreseen for this type of fittings includes one steering computer system 1 which is fixedly mounted on the outside of the vehicle.

The coordination computer system 1 stores the standard values of the motion parameters in one or several vehicles, where this standard value is involved in the accident that is reproduced.

In addition, the coordination computer system 1 actually controls the actual value of the motion parameters implemented by the vehicle 8 at that time.

The adjusting computer system 1 then defines the deviation between the standard value and the actual value and delivers the necessary corrector.

The corrector is necessary to correctly implement the exercise parameters shown in the actual accident scene.

The coordination computer system 1 is coupled with an induction cable transmitter 2 via an information induction device.

The induction cable transmitter 2 can in that case also be additionally made as a receiver.

The induction cable transmitter 2 can be made in one line and in some cases in several lines for the exchange of information between the steering computer system 1 and the travel control means 5.

By means of a battery buffer the induction cable transmitter 2 is independent of the external power supply. In addition, the induction cable transmitter 2 presents one or additional several input frequencies which are inserted to adjust the direction of the vehicle.

For the adjustment of the parameters, the travel control means 5 is connected with the direction cylinder means 11 to enter the direction means 10 of the front wheel, for example in the manner described in the figure.

Thus, the control of the direction of movement makes it possible to drive the vehicle 8 as if the last turn occurred just before the accident according to the induction cable 3.

The connection of the driving control means 5 to various places is made for controlling the speed and controlling the brake operation. The brake manipulator 12 is directly connected to the driving control means to release the brake operation. The brake manipulator 12 can explain the driver's response just before the accident, such as stepping on the brake or complete braking.

In addition, the brake manipulator 12 is configured with an emergency braking function, so that the vehicle can be forcibly stopped at the time of departure of the vehicle from the induction cable or in case of lack of technical equipment.

The speed is adapted to the standard value of the speed given by the travel regulating means 5 with the aid of the sensor 14, originally made in the form of a speed sensor. The speed regulating means 13 then directly interferes with the throttle, but can be made in continuous form over time.

The running of the vehicle 8 along the induction cable 3 essentially moves in it the vehicle itself. This means, for example, that the tracer device is sensitively controlled or otherwise controlled in relation to the induction cable 3 via the antenna 4 and in some cases by means of the intervention of the travel control means 5. To be modified in (11). The adjustment of the speed still takes place only by the vehicle, ie only by the travel control means.

The instantaneous actual speed is always precisely defined with the aid of the speed sensor 14 and can be adapted to the standard value via the speed regulating means 13 with the aid of the travel control means.

If there are two or several vehicles that are designed to be guided to the point of collision according to signals from various directions, the precise definition of the point of impact and relative position between the vehicles, including absolute and relative speeds, is aided by the coordination computer system. This can be done with the help of trigger markings on inductive cables.

Its value is compared with the corresponding standard and, in some cases, with the aid of the operating cylinder, the speed regulating means 13 and the brake manipulator 12, passing the induction cable transmitter 2 and the induction cable 3 and the driving regulating means 5 Intervention to) ensures that the vehicle meets this standard. The adjustment computer system 1 is thus arranged above the travel control means 5 and is designed to adjust the motion parameters as a higher device than the travel control means.

In order for the equipment in the vehicle to operate on its own, all functions, such as the driving control means 5, are operated by the battery of the vehicle, as in ordinary vehicles.

A sensor 16 with a wide range of functions is attached to the vehicle to record important measurement signals while the accident is in progress. The sensor 16 is connected to the in-vehicle computer system 6 and is made to function to improve and store the measurement signals. In addition, the inductive device 19 is connected to the antenna or the driving control means.

The in-vehicle computer system 6 thus grasps the motion parameters that may be affected by the in-vehicle computer system. For example, with respect to the antenna 4, the in-vehicle computer system 6 can be operated including the sensor 16. In-vehicle computer system 6 has its own power supply 17 therein.

The in-vehicle computer system 6 is therefore guaranteed for the entire experimental period without being powered from the vehicle battery 15. In addition, the travel control means 5, the power supply 17 and the sensor 16 are particularly carefully attached to the vehicle body.

The measurements delivered by the sensor 16 to the in-vehicle computer system 6 are stored in the in-vehicle computer system 6 and later evaluated.

It is also possible to store the measurement price by means of the in-vehicle computer system 6 and transmit it to a storage facility which is not broken by an accident outside of the vehicle.

Each experimental type of installations designed for the reproduction of car accidents is equipped with the corresponding unique facilities in the body according to the vehicle involved in the accident and leading to the collision point.

Accurate adaptation to the motion parameters of all vehicles is made possible by the higher coordination computer systems for coordination with each other as well as with the standard values given by the accident situation.

In Fig. 2, another embodiment of this concept is depicted. Parts corresponding to those in FIG. 1 show the same relationship and will only be mentioned in part.

In this example of implementation, instead of the antenna 4 of FIG. 1, a laser receiving apparatus 20 is attached to the front of the vehicle 8. It is combined with the travel control means 5 and the in-vehicle computer system 6.

The adjustment inside the vehicle is similar to that described in FIG. 1, and nothing newly described in relation to FIG. 2.

The laser 21 is attached to or near the point of impact and leads the vehicle 8 to the point of impact with the aid of the laser beam 22 received by the laser beam receiving facility 20. The deviation of the vehicle direction 18 and the laser beam 22, which occur in some cases, is corrected in accordance with the practice exercises with the antenna and the induction cable by one or both of the in-vehicle computer system 6 and the drive control means 5 So that the directions of both coincide.

The steering computer system 1 lies outside of the vehicle 8, for example by means of a cable, which is connected to the laser 21 or by means of a drive control means 5 attached to the vehicle 8. And in-vehicle computer system 6.

In FIG. 3, a typical accident situation is exemplarily illustrated.

Vehicles 27 and 28 respectively run in the direction of 33 or 32 over two roads 24 and 25 that cross each other.

At the point of impact 34 the two vehicles must meet each other. The laser beam receiver 30 or 31 is provided in front of the vehicle 26 and 27. As shown in FIG. A track tracking device 38 or 37 is placed in the length of the vehicle direction 32 or 33 from the vehicle 26 or 27 to the collision point 34.

The laser beam 35 or 36 exits here, and the laser beam enters the laser beam receiving facility 30 or 31. Along these laser beams 35 and 36, the vehicles 26 and 27 move in the direction of 32 or 33 to lead to the point of impact 34.

This conception according to FIG. 1 is implemented with an induction cable 39 or 40 on or inside the road. Along this induction cable, vehicles 26 and 27 are led to the point of impact 34 with the aid of the antenna 4.

According to this idea, all vehicles involved in the accident process can be configured as either a laser beam guidance system, an induction cable system, or a combination of both systems.

It is to develop the equipment to test the impact of the car accident of the present invention more widely, so that the actual accident can be reproduced. In addition, some equipment can be attached, which leads to one or several vehicles corresponding to the accident situation.
