Description

Indicator of the degree of danger of the safety distance.

Technical sector

The invention falls within the technical sector of road safety and more specifically in signaling.

State of the art

I do not know precedents to this invention.

Explanation of the invention.

The present invention aims at, report the degree of danger of our distance from security.

This degree or level is born from the relationship between our speed and the distance between our vehicle and Any object in its path.

A sensor gives us the speed of Our vehicle and a distance meter offers us the distance existing between our vehicle and an object in its trajectory.

The speed at which we circulate is received by an electronic module which has distance tables optimal, programmed with some parameters, by means of which module, offers for each speed value it receives, a value of corresponding optimum safety distance.

Different vehicle accessories as they can be lights, windshield wipers, fog lights, etc. send current with its operation, to some switches of the electronic module.

This current closes the switch that the receives and puts into operation the optimal distance table that have associated to provide at each speed, a distance of optimum security most appropriate to the conditions to which we circulate

When no switch receives power from the operation of the connected accessories, the electronic module you have activated an optimal distance table for conditions normal circulation, which we designate as the distance table main optimal.

The distance meter readings are received by the electronic module, which through a converter away, it gives us the distance values of real security

The electronic module makes a relationship between the optimum safety distance and the safety distance real, placing the result in a table of ranges of values.

The degree of danger of the distance of security, is determined by the range that contains the value of the result of the distance relationship.

Each of the ranges is associated with a action, which can be executed by different devices connected to the electronic module.

Description of the figure

Variations in vehicle speed are collected by the sensor (1) and received by the electronic module (3).

Depending on the accessory we are using, with its operation sends current to a switch in the control panel switches (I) having dinner and connecting the table Optimum distance (TD) associated with it.

As an example, of connections (a) none main optimal distance connection or table, (b) dipped beam lights, and (c) windshield wipers.

In Figure 1 the dinner switch is (a).

The distance meter (2) collects the variations of the safety distance that are received by the module (3) which, through the distance converter (CD), we provides the value of the actual safety distance (D2).

The electronic module (3) makes a relationship between the two distances (D1) and (D2).

The result of this relationship is located in a table of ranges of values (TR), where each range generates different actions (x1, x2, x3, x4), as an example: x1 light green, x2 yellow light, x3 orange light and x4 red light, which are received by devices connected to the electronic module to be executed

Embodiments of the invention

We carry out the invention of the following shape:

A meter is commercially acquired Ultrasonic distance for object detection in our trajectory, such as a vehicle that precedes ours, a fence of a work, animals, people etc. for distances between 0 and 200 meters, with values from 0 to 10 volts.

A jumper (connection) of the sensor is made which the vehicle has factory installed to know the speed and which gives us a voltage of 0 to 10 volts for speeds from 0 to 180 km / h.

The electronic module is acquired in the market, such as the Siemens Logo programmable relay with inputs analog and digital

It is determined how to display the information obtained, in this case with a small LED bar, with four colors above the driver's frame and a dimension bar older on the upper side of the rear glass rectangle, with the same range of colors to be observed by the driver who It follows us.

The optimal distance table is programmed main, introducing a multiplier factor that we get from the relationship between the speed sensor and its capabilities, applying a rule of 3, if at 10 volts corresponds to 180 km / h, to 1 volt, corresponds to 18 km / h divided by 3.6 to pass it to m / sec we get 5 meters traveled per second for a reading of 1 volt, for the main optimal distance table we program that the safety distance, be the space traveled during 3 seconds at the speed at which it circulates, 5 m / sec x 3 sec = 15 meters, the factor of this table is 15.

The meter converter is programmed distance applying a rule of 3, if at 10 volts corresponds to 200 meters, 1 volt corresponds to 20 meters, the factor is twenty.

The relationship between distances is programmed (real and optimal) with a division between them.

The ranges of values are programmed:

GREEN: 0 \ rightarrow 1

YELLOW: 1.01 ? 1.50

ORANGE: 1.51 ? 2.70

RED: 2.71 IN AHEAD

The entire assembly is installed in the vehicle.

The set is calibrated for correct functioning.

Performance of the realization

The speed sensor performs a reading of 5.4 volts, multiplied by the distance table factor main optimum, gives us the value of the safety distance optimal (D1) 5.4 x 15 = 81 meters.

The distance meter gives a reading of 3 volts, multiplied by the converter factor, gives us a value of real distance (D2) 3 x 20 = 60 meters.

It is divided (D1 / D2) 81/60 the result is 1.35 remaining the value located in the second range, which comprises of 1.01 to 1.50 being the associated action the yellow light, which corresponds to a medium degree of danger.

With a connection between the driver's control and the windshield wiper motor, current is sent with its operation to another switch of the electronic module, which remains closed, activating another optimal distance table, which has programmed 4 sec. of space traveled at the speed at which we circulate optimal safety distance, being the factor multiplier 5 m / sec x 4 sec = 20 meters.

We apply the multiplier factor of this new Optimum distance table to speed sensor reading, 5.4 volts x 20 = 108 meters of optimal safety distance (D1).

It is divided (D1 / D2) 108/60 the result is 1.8 remaining the value located in the third range, the action being associated orange light that corresponds to a degree of danger medium-high or precautionary.

At equal distance and speed values, with the operation of the windshield wiper changes the distance of optimum safety required by rain, showing the device a higher degree of danger.
