Description

INTRODUCTION

[001] The present invention patent deals with an intelligent and embedded automation system for collecting positioning and approximation data (Vehicle B) in the back of another moving or stopped vehicle (Vehicle A), in real time. It creates a complementary signaling system for approaching vehicles, by means of a light signal and independent of the existing lights and brake pedal, thus enabling the automatic perception of the risk situation involving the vehicles in the context.

FIELD OF THE INVENTION

[002] The invention in question has its application in the automotive industry, and can be used in any vehicle, used or new, regardless of its classification (cars, motorcycles, trucks, etc.).

CONVINCMENT

[003] The automobile industry has used, since the beginning, the same rear signaling system, which works as a binary system, that is, if the driver steps on the brake, the red light turns on and remains off if he does not step on the brake.

[004] A few years ago there was an improvement in signaling when the so-called "break light" was created, which is nothing more than a third lamp installed in the rear window or another position, but working in parallel with the binary system, described above, that is, being controlled by the brake pedal.

STATE OF THE TECHNIQUE

[005] The current state of the art anticipates some patent documents that deal with rear brake signaling, such as PI 9800070-5, entitled “'Auxiliary signaling system for motor vehicles'” - enables: a) at each braking that is made, intermittent activation of auxiliary brake lights for a short time, and then their continuous activation until the end of braking; b) the intermittent activation of ref. lights for a short time when your pedal is pressed lightly without causing braking.

[006] Document MU8000409-1 entitled “Automotive signaling for effective braking - (safe)” - adds two receivers/transmitters of infrared rays (IR) in each motor vehicle. The set consists of a front device and a rear device, both with different functions of receivers and transmitters of ri or electric current triggering this thermal energy switched by relays. In addition to the RI transmitter, the rear device, which may be independent, integrated to the "brakelight" or to the set of rear brake lights - will have a signaling lamp for effective or imminent brake action.

[007] The above document presents the biggest drawback is that for operation, the system must be implemented in the entire fleet of circulating vehicles.

[008] Document PI 0722620-9 entitled “Deceleration light or anticipatory brake signal light in motor vehicles” - system that indicates that the driver of a vehicle takes his foot off the accelerator and, as a result, the vehicle will slow down or even come to a halt. It consists of installing a deceleration sensor and an indicator light in the vehicle at the rear of the vehicle, a deceleration sensor and an indicator light at the rear of the vehicle, which are interconnected by electrical cables and work when the driver takes his foot off the accelerator.

[009] Document PI 0500510-8 entitled “intelligent brake light indicator” - consists of an optical sensor installed on the accelerator pedal on the accelerator pedal, which anticipates the braking alert by two seconds.

[010] Although the documents anticipated by the current state of the art, perform, in a way, well the function for which they were designed, they still leave some gaps that generate risk situations that are covered by the proposed invention.

DETAILED TECHNICAL DESCRIPTION OF THE INVENTION

[024] “COMPLEMENTARY REAR SIGNALING SYSTEM FOR AUTOMOTIVE AND SIMILAR VEHICLES”, deals with a system in which sensors (1) of distance and/or movement are installed in a vehicle A, which delimit a controlled zone (2), automatically adjustable or via APP (7), in relation to a vehicle B, whose data are processed by a processing module (3) in order to, in vehicle A, activate an additional rear signal light L1 (4) or additional rear signal light L2 (4'), activate a rear camera (5) and/or an audible alarm (6), all with the aim of alerting vehicle B of its dangerous position in relation to vehicle A, as well as being able to use data from images collected and recorded to resolve doubts that may exist in adverse situations, as well as to alert the driver of vehicle A of dangerous approaches in the controlled zone (d2) of vehicle B, by sound signal (6).

[025] More particularly, the invention deals with a system in which a vehicle A is installed sensors (1) of distance and or movement, whose distances collected by the processing module (3) are fully adjustable by the control APP (7), or automatically by a specific algorithm, in order to define the type of environment it is in, and position it in the specific controlled zone (2). The controlled zone (2) varies according to the environment in which vehicle A is located, and can be adjusted for use on highways, normal traffic, traffic jams and parked vehicle. The different environments modify the distances at which the signal lights, rear supplementary L1 (4) and rear supplementary signal light L2 (4') will be activated, due to the different speeds and braking area, depending on the distances between vehicles B and vehicle A, for each environment. The system has a default for each room in the controlled zone (2), with room adjustments being made automatically.

[026] In turn, the distance and/or movement sensors (1) may be laser, microwave or other technologies, and their function is to continuously verify the distance between vehicle B and vehicle A, providing data for the processing module (3) to make a classification decision of what kind of environment it is, depending on the speed and the distance between the vehicles, for the automatic activation of the signal light, complementary rear L1 (4) and signal light rear complementary L2 (4'). The processing module (3) comprises a microprocessed electronic circuit, with embedded technology, for collecting data from sensors (1) of distance and/or movement for decision making to turn off or on different stages of the complementary rear signaling light L1 (4) and additional L2 rear signal light (4'). The processing module (3) communicates via radio with the APP (7) of the cell phone and triggers the rear camera (5) to record events, according to predefined settings. The complementary rear signaling light L1 (4) and the complementary rear signaling light L2 (4') are located on a rear signaling panel in vehicle A, which can have its signaling characteristic modified by the APP (7), being able to show the distance between vehicles numerically or in the form of luminous stages, depending on the setting. The rear camera (5), with the function of collecting and recording images (filming and/or photographing and storing) from a stage that denotes the controlled zone (d2) of dangerous approach, the behavior of vehicle B, can be activated at any time situation in which vehicle A is found, i.e. moving, stopped or parked. The control APP (7) is software to be downloaded onto the user's cell phone, where he will be able to carry out a behavior and statistical analysis of the different vehicles B, which were inside the controlled zone (2), as well as make changes to default parameters presets, share information, among other functions.

[027] According to figure 3, the system is based on an operating logic of five data inputs A, B, C, D and E, in addition to three logic outputs activating a complementary rear signaling light L1 (4), a light supplementary rear signal light L2 (4') and a rear camera (5) together with the supplementary rear signal light L2 (4'), an audible alarm (6) and an APP (7).

[028] To verify operation, just check the truth table, which has the results as follows: J If input E is at high level (1), the system is inoperative, which is the case of vehicle A reversing. Input E is barred to all outputs of type "and" gates; J If vehicle A is on (C at level 1) and stationary (D at level 0), the rear auxiliary light L1 (4) will "always" be on; J If vehicle A is on (C at Level 1) and vehicle B enters the control zone (2) of distance d1 (A at level 1), the rear additional signal light L1 (4) will light up. If vehicle A is stationary, the additional rear signal light L1 (4) will already be on, therefore it applies to cases where vehicles A and B are moving; J If vehicle A is on (C in level 1) and vehicle B enters the control zone (2) of distance d2 (B in level 1), the audible alarm (6) will be activated in vehicle A, additional signal light rear camera L2 (4') and the rear camera (5) will start recording images; J If vehicle A is turned off (C at level 0) and vehicle B enters the distance control zone d2, the additional rear signal light L2 (4') and the additional rear camera (5) will be activated. This is the case of the parked vehicle;

[029] It should be noted that the entire adjustment and statistics system can be accessed via the APP (7) on the cell phone and/or multimedia center of vehicle A.

[030] In summary, the schematic consists of five data inputs A, B, C, D and E, which pass through four "and" type logic gates and an "or" type logic gate, and three outputs that can trigger two signaling levels, additional rear signaling light L1 (4), additional rear signaling light L2 (4'), auxiliary rear camera (5) and audible alarm (6).
