Description

MÉTODO E SISTEMA DE BLOQUEIO AUTOMOTIVO ANTIFURTO/ROUBO UNIVERSAL UNIVERSAL ANTI-THEFT/THEFT AUTOMOTIVE LOCKING SYSTEM AND METHOD
CAMPO DA INVENÇÃO FIELD OF THE INVENTION
[001] A presente invenção é aplicada no campo dos dispositivos antifurto/roubo de automóveis, mais especificamente, em bloqueadores de veículos. [001] The present invention is applied in the field of car anti-theft/theft devices, more specifically, in vehicle locks.
ANTECEDENTES DA INVENÇÃO BACKGROUND OF THE INVENTION
[002] Atualmente, com o crescimento dos crimes de roubo e furto de veículos, diversas empresas do ramo de segurança estão investindo cada vez mais em tecnologia para combater esse mal. Nesse sentido, vários sistemas para bloquear o funcionamento do veículo em caso de roubos e furtos já estão presentes no estado da técnica. [002] Currently, with the growth of crimes of theft and theft of vehicles, several companies in the security field are investing more and more in technology to combat this evil. In this sense, several systems to block the operation of the vehicle in case of robberies and thefts are already present in the state of the art.
[003] Os sistemas conhecidos de bloqueio antirroubo veicular são acionados ao ocorrer alguma violação no mecanismo rastreador presente no veículo. Porém, a comunicação entre o bloqueador e o rastreador (geralmente através de um simples fio) é facilmente desviada, burlando essa comunicação com certa tranquilidade pelos criminoso. [003] The known vehicle anti-theft locking systems are triggered when there is a violation in the tracking mechanism present in the vehicle. However, the communication between the blocker and the tracker (generally through a simple wire) is easily diverted, bypassing this communication with certain tranquility by the criminal.
[004] Um segundo problema é que os bloqueadores conhecidos têm configurações específicas para se comunicarem com cada tipo de dispositivo. Em diversos casos há a necessidade de uma nova saída de comunicação do bloqueador a cada troca de rastreador, gerando assim, um aumento de custo. [004] A second problem is that known blockers have specific settings to communicate with each type of device. In several cases, there is a need for a new blocker communication output at each tracker change, thus generating a cost increase.
[005] Por fim, ainda existe a possibilidade do furto acontecer sem que ocorra o corte da comunicação entre o bloqueador e os demais componentes do carro. Essa modalidade de furto ocorre quando o criminoso, com auxílio de equipamento específico, acessa a porta OBD II para a programação, no computador do veículo, de uma nova chave. Com essa nova chave programada, o veículo passa a identifica-la e aceita-la para dar partida no motor do veículo. [005] Finally, there is still the possibility of the theft happening without cutting off the communication between the blocker and the other components of the car. This type of theft occurs when the criminal, with the help of specific equipment, accesses the OBD II port to program a new key on the vehicle's computer. With this new programmed key, the vehicle starts to identify and accept it to start the car. vehicle engine.
[006] O documento MU 9000752-2 revela um "SISTEMA DE ALARME E BLOQUEADOR VEICULAR VIA GSM" com diversas funcionalidades como rastreamento, bloqueio e ativação de alarmes. Porém, como dito anteriormente e exemplificado por este documento, o estado da técnica não resolve o problema da comunicação entre o rastreador e o bloqueador ser facilmente desfeita pelo criminoso e nem do acesso ao computador do veículo para gerar uma nova chave de partida do motor. [006] Document MU 9000752-2 reveals an "ALARM SYSTEM AND VEHICLE BLOCKER VIA GSM" with various features such as tracking, blocking and activation of alarms. However, as previously mentioned and exemplified by this document, the state of the art does not solve the problem of communication between the tracker and the blocker being easily undone by the criminal, nor access to the vehicle's computer to generate a new engine start key.
[007] Outro exemplo do estado da técnica é o documento BR 102016020312-0, esse pedido de patente revela uma comunicação sem fio entre o rastreador e o bloqueador. Porém, apesar de trazer uma alternativa para a comunicação rastreador-bloqueador, é uma solução de alta complexidade e de custo bem elevado. Adicionalmente, não resolve o problema trabalhar com qualquer rastreador, sem a necessidade de modificar a saída de comunicação do bloqueador e muito menos o problema da troca da chave de acesso à partida do motor através da porta OBD II do veículo. [007] Another example of the state of the art is the document BR 102016020312-0, this patent application reveals a wireless communication between the tracker and the blocker. However, despite providing an alternative for tracker-blocker communication, it is a highly complex and costly solution. Additionally, it does not solve the problem of working with any tracker, without the need to modify the blocker's communication output, much less the problem of changing the access key to starting the engine through the vehicle's OBD II port.
SUMÁRIO DA INVENÇÃO SUMMARY OF THE INVENTION
[008] A presente invenção consiste em uma alternativa versátil, de baixo custo, e maior segurança para sistemas de rastreamento e bloqueio de veículos. [008] The present invention consists of a versatile, low-cost, and more secure alternative to vehicle tracking and blocking systems.
[009] A versatilidade e o baixo custo são alcançados ao eliminar a necessidade de o bloqueador ter saídas de comunicação específicas para cada tipo de dispositivo (rastreadores, dispositivos de identificação pessoal, capas de proteção para porta OBD II, dispositivos com ID ou de proximidade), tornando a presente invenção uma alternativa universal para o bloqueio veicular. [009] Versatility and low cost are achieved by eliminating the need for the blocker to have specific communication outputs for each type of device (trackers, personal identification devices, protection covers for OBD II ports, devices with ID or proximity ), making the present invention a universal alternative for vehicle blocking.
[0010] A maior segurança se deve pelo fato da comunicação do sistema dispositivo-bloqueador não pode ser desativada externamente, já que qualquer interferência é automaticamente percebida pelo bloqueador. [0010] Greater security is due to the fact that the device-blocker system communication cannot be disabled externally, since any interference is automatically detected by the blocker.
[0011] Adicionalmente, a presente invenção permite a adição de uma capa de proteção com identificação, podendo a identificação ser um resistor, sobre a porta OBD II do veículo que impede a inserção de qualquer tipo de equipamento mesmo que de forma paralela, pois isso mudaria os parâmetros do dispositivo reconhecido pelo bloqueador e acarretaria no bloqueio do veículo. [0011] In addition, the present invention allows the addition of a protection cover with identification, the identification may be a resistor, on the OBD II port of the vehicle that prevents the insertion of any type of equipment even if in parallel, as this would change the parameters of the device recognized by the blocker and lead to the blocking of the vehicle.
[0012] O MÉTODO E SISTEMA DE BLOQUEIO AUTOMOTIVO ANTIFURTO/ROUBO UNIVERSAL foram projetados para reconhecer uma faixa predeterminada de resistência (Ohm) e/ou de corrente (Ampère) relacionada ao rastreador ou a qualquer outro dispositivo de reconhecimento de motorista ou ainda qualquer outro dispositivo que possa ser removido pelos bandidos quando uma tentativa de furto/roubo estiver em andamento. Essas faixas de resistência e corrente são programadas no momento da instalação do bloqueador e podem ser facilmente alteradas caso haja a mudança do dispositivo rastreador. [0012] THE UNIVERSAL ANTI-THEFT/THEFT AUTOMOTIVE LOCKING METHOD AND SYSTEM is designed to recognize a predetermined range of resistance (Ohm) and/or current (Ampère) related to the tracker or any other driver recognition device or any other device that can be removed by thieves when an attempted theft/robbery is in progress. These resistance and current ranges are programmed when installing the choke and can be easily changed if the tracking device changes.
[0013] A partir do momento em que ocorre qualquer interferência externa na comunicação entre o bloqueador e o dispositivo (sendo esse dispositivo um rastreador, dispositivo de identificação pessoal, capa de proteção para porta OBD II, dispositivos com ID ou de proximidade) ou mesmo uma interferência diretamente no dispositivo, o bloqueador reconhece a alteração do valor da resistência ou corrente e aciona o bloqueio do funcionamento do carro. [0013] From the moment any external interference occurs in the communication between the blocker and the device (being this device a tracker, personal identification device, protection cover for OBD II port, devices with ID or proximity) or even interference directly on the device, the blocker recognizes the change in the resistance or current value and triggers the blocking of the car's operation.
[0014] O bloqueio é feito de forma já conhecida no estado da técnica, a unidade de controle eletrônica (ECU) do veículo é conectada (através de fios) ao relé do bloqueador que por sua vez se conecta a sensores, rede CAN (Controller Area Network), motor de partida ou qualquer um dos relés ligados a pontos vitais para o funcionamento do veículo (bomba de combustível, imobilizador, bobina de ignição, etc.). No momento que é acionado, o relé do bloqueador corta a comunicação entre o ECU e um ou mais pontos supracitados, cessando o funcionamento do mesmo. [0015] Uma situação comum de bloqueio seria em casos de roubo a caminhões de carga. Assim que constatado o roubo, uma central acessa o sistema do rastreador, verificando onde está o veículo e enviando um comando para o rastreador solicitar a ativação do bloqueador, que inicia o bloqueio progressivo do caminhão. Porém, é comum ladrões especializados terem tecnologia para localizar e remover esse rastreador, burlando o bloqueio do caminhão. Caso o caminhão esteja equipado com o MÉTODO E SISTEMA DE BLOQUEIO AUTOMOTIVO ANTIFURTO/ROUBO UNIVERSAL, o veículo sera bloqueado assim que ocorrer a remoção do localizador, impedindo assim, a continuação da ação criminosa. [0014] The blocking is done in a way already known in the state of the art, the electronic control unit (ECU) of the vehicle is connected (through wires) to the blocker relay which in turn connects to sensors, CAN network (Controller Area Network), starter motor or any of the relays connected to vital points for vehicle operation (fuel pump, immobiliser, ignition coil, etc.). When activated, the blocker relay cuts off the communication between the ECU and one or more points mentioned above, ceasing its functioning. [0015] A common blocking situation would be in cases of theft of cargo trucks. As soon as the theft is confirmed, a central accesses the tracker's system, checking where the vehicle is and sending a command to the tracker to request the activation of the blocker, which initiates the progressive blocking of the truck. However, it is common for specialized thieves to have the technology to locate and remove this tracker, bypassing the truck lock. If the truck is equipped with the UNIVERSAL ANTI-THEFT/THEFT AUTOMOTIVE LOCKING SYSTEM AND METHOD, the vehicle will be blocked as soon as the locator is removed, thus preventing the continuation of the criminal action.

[0020] A presente patente propõem um MÉTODO E SISTEMA DE BLOQUEIO AUTOMOTIVO ANTIFURTO/ROUBO UNIVERSAL capaz de funcionar com qualquer dispositivo (20) como: rastreadores, dispositivos de identificação pessoal (teclados, dispositivos com ID, dispositivos de proximidade, etc.) ou até mesmo com qualquer outro dispositivo que possa ser removido pelo bandido na hora do roubo/furto (como a capa protetora da porta OBD II). [0020] This patent proposes a UNIVERSAL ANTI-THEFT/THEFT AUTOMOTIVE LOCKING SYSTEM AND METHOD capable of working with any device (20) such as: trackers, personal identification devices (keyboards, devices with ID, proximity devices, etc.) or even with any other device that can be removed by the thief at the time of robbery/theft (such as the protective cover of the OBD II port).
[0021] O MÉTODO DE BLOQUEIO AUTOMOTIVO ANTIFURTO/ROUBO UNIVERSAL compreende o bloqueador (10) que se comunica com o dispositivo (20), estando o bloqueador (10) conectado com o ECU (30) e com um ou mais pontos vitais do veículo e possui as seguintes etapas de funcionamento: [0021] THE UNIVERSAL ANTI-THEFT/THEFT AUTOMOTIVE LOCKING METHOD comprises the blocker (10) that communicates with the device (20), the blocker (10) being connected with the ECU (30) and with one or more vital points of the vehicle and has the following operating steps:
• o bloqueador (10) verifica a corrente e/ou resistência associada ao dispositivo (20), • the blocker (10) checks the current and/or resistance associated with the device (20),
• o bloqueador (10) fica em "modo espera" caso não seja verificado alteração fora da faixa estipulada para corrente e/ou resistência associada dispositivo (20), • the blocker (10) is in "standby mode" if no change is verified outside the stipulated range for current and/or resistance associated with the device (20),
• acontecendo alteração da corrente e/ou resistência fora da faixa previamente estabelecida, o bloqueador (10) é acionado e faz o corte da comunicação entre o ECU (30) e um ou mais pontos vitais para o funcionamento do veículo. • If there is a change in current and/or resistance outside the previously established range, the blocker (10) is activated and cuts off communication between the ECU (30) and one or more vital points for vehicle operation.
[0022] Os pontos vitais para o funcionamento do veículo são diversos, entre eles: os relês (40) do imobilizador, bomba de combustível, bobina de ignição ou ainda os sensores do veículo, motor de partida e/ou rede CAN. [0022] There are several vital points for the operation of the vehicle, including: the immobilizer relays (40), fuel pump, ignition coil or vehicle sensors, starter motor and/or CAN network.
[0023] O bloqueador (10) funciona sempre verificando a resistência e/ou corrente do dispositivo (20) conectado a ele. Partindo desse fato, o bloqueador segue em modo de espera quando a leitura da resistência e/ou da corrente do dispositivo (20) está na mesma faixa que a estabelecida. A faixa de resistência e/ou corrente são programadas na fabricação do bloqueador (10), entretanto, podem ser reprogramadas momento de instalação do bloqueador (10) com o dispositivo (20) caso seja necessário. [0023] The blocker (10) always works checking the resistance and/or current from the device (20) connected to it. Based on this fact, the blocker remains in standby mode when the resistance and/or current reading of the device (20) is in the same range as the established one. The resistance range and/or current are programmed in the manufacture of the blocker (10), however, they can be reprogrammed at the moment of installation of the blocker (10) with the device (20) if necessary.
[0024] Caso haja alteração da leitura de qualquer um dos dois parâmetros supracitados para fora das faixas previamente programadas, o bloqueador (10) aciona o corte à algum ponto vital do veículo (mostrado na figura 1). [0024] If there is a change in the reading of any of the two aforementioned parameters outside the previously programmed ranges, the blocker (10) triggers the cut at some vital point of the vehicle (shown in figure 1).
[0025] A alteração da resistência ocorre quando o fio entre o dispositivo (5 ou 6) e o bloqueador é cortado ou a alimentação do dispositivo (20) é cortada ou o próprio dispositivo (20) é retirado ou ainda quando o dispositivo (20) envia algum sinal de bloqueio para o bloqueador (10). [0025] The resistance change occurs when the wire between the device (5 or 6) and the blocker is cut or the power supply to the device (20) is cut or the device itself (20) is removed or even when the device (20 ) sends some blocking signal to the blocker (10).
[0026] O sistema sempre compreenderá bloqueador (10), dispositivo (20), unidade de controle eletrônica (30) e um ou mais pontos vitais do veículo. Sendo que o bloqueador (10) compreende a placa de circuito (1), relê (2) e microcontrolador (11). [0026] The system will always comprise blocker (10), device (20), electronic control unit (30) and one or more vital points of the vehicle. Since the blocker (10) comprises the circuit board (1), relay (2) and microcontroller (11).
[0027] Para o caso do dispositivo (20) ser eletrônico, a medição da resistência (Ohm) é realizada pelo microcontrolador (11) com uma de suas entradas analógicas (12) ligada ao transistor (9) do circuito de saída digital do dispositivo (20). Dessa maneira, é lida a resistência desse transistor (9), dando as opções de ação para o bloqueador (10). [0027] In case the device (20) is electronic, the resistance measurement (Ohm) is performed by the microcontroller (11) with one of its analog inputs (12) connected to the transistor (9) of the digital output circuit of the device (20). In this way, the resistance of this transistor (9) is read, giving the action options for the blocker (10).
[0028] Para a medição da corrente, a fonte de tensão elétrica do carro (medida em volts) é conectada ao bloqueador (10) que envia essa tensão para a entrada de alimentação do dispositivo (20) e assim a corrente que passa no bloqueador (10) para a entrada de alimentação do dispositivo (20) é lida pelo microcontrolador (11). [0028] For current measurement, the car's electrical voltage source (measured in volts) is connected to the blocker (10) which sends this voltage to the device's power input (20) and thus the current flowing through the blocker (10) to the power input of the device (20) is read by the microcontroller (11).
[0029] Caso a leitura de resistência e/ou a corrente esteja na mesma faixa que a programada para aquele dispositivo (20), o bloqueador (10) segue em "modo de espera", ou seja, não é realizada nenhuma ação. [0029] If the resistance and/or current reading is in the same range as that programmed for that device (20), the blocker (10) continues in "standby mode", i.e. no action is taken.
[0030] Sendo verificada a alteração de valor de resistência e/ou da corrente pelo microcontrolador (11), o mesmo aciona o relê do bloqueador (2) que corta a comunicação do ECU com algum ponto estratégico do carro. [0030] Once the change in resistance value and/or current is verified by the microcontroller (11), it activates the blocker relay (2) that cuts off communication between the ECU and a strategic point in the car.
[0031] O relé é uma peça já conhecida no estado da técnica e basicamente funciona abrindo e fechando circuitos quando recebem um comando vindo de um microcontrolador, por exemplo. O relé pode ser comparado a um interruptor para que pessoas menos versadas na técnica compreendam. [0031] The relay is a part already known in the state of the art and basically works by opening and closing circuits when they receive a command from a microcontroller, for example. The relay can be compared to a switch so that people less versed in the art will understand.
[0032] Para o caso específico, o relé (2) funcionará conectando o circuito ECU (30) - relé (40) e/ou ECU (30) - motor de partida e/ou ECU (30) - sensores e/ou ECU (30) - rede CAN, como se o interruptor estivesse ligado, ao receber o sinal do microcontrolador (11), o relé (2) abre o circuito, impedindo a comunicação entre o ECU (30) com um ou mais dos componentes citados. [0032] For the specific case, the relay (2) will work by connecting the circuit ECU (30) - relay (40) and/or ECU (30) - starter motor and/or ECU (30) - sensors and/or ECU (30) - CAN network, as if the switch were on, upon receiving the signal from the microcontroller (11), the relay (2) opens the circuit, preventing communication between the ECU (30) and one or more of the aforementioned components.
[0033] O bloqueio também ocorre quando se envia um comando de bloqueio (via sms, aplicativo ou central de controle) para o dispositivo (20), já que a resistência e/ou corrente lida pelo microcontrolador (11) atinge um valor diferente dos anteriores quando ocorre esse tipo de acionamento e, assim como na suposição anterior, o microcontrolador (11) envia um comando para o relé (2) cortar a comunicação entre o ECU e um dos pontos vitais do veículo. [0033] Blocking also occurs when a blocking command is sent (via sms, application or control center) to the device (20), since the resistance and/or current read by the microcontroller (11) reaches a value different from those when this type of activation occurs and, as in the previous assumption, the microcontroller (11) sends a command to the relay (2) to cut the communication between the ECU and one of the vital points of the vehicle.
[0034] Para a realização em que o dispositivo (20) se tratar da capa protetora (Figura 4) da entrada OBD II do veículo, surge a necessidade de se programar um protocolo de reconhecimento onde o responsável pela remoção da capa protetora terá um limite de tempo, apenas alguns segundos, para dar partida no motor do veículo antes que ocorra o acionamento do bloqueador (10), com isso, não tendo tempo hábil para a programação de uma nova chave para ignição do motor do veículo conforme descrito anteriormente. Caso o motor seja acionado antes do tempo estipulado, o bloqueador (10) não envia sinal de bloqueio de algum ponto vital para o funcionamento do veículo, mesmo sem a presença da capa protetora do OBD II. Esse tempo de partida é ajustável, podendo ser de 10 a 60 segundos, por exemplo. [0035] Tal necessidade aparece, pois a porta OBD II (On Board Diagnostics) é utilizada para realizar a conexão do computador do veículo com um dispositivo de leitura de diversos parâmetros de funcionamento do veículo, então caso o bloqueador (10) fosse acionado em todos os casos que a capa protetora fosse retirada, inviabilizaria o uso desses dispositivos de leitura e análise para realizar uma revisão, por exemplo. [0034] For the implementation in which the device (20) is the protective cover (Figure 4) of the vehicle's OBD II port, there is a need to program a recognition protocol where the person responsible for removing the protective cover will have a limit of time, just a few seconds, to start the vehicle's engine before the blocker (10) is activated, thus not having enough time to program a new ignition key for the vehicle's engine as described above. If the engine is started before the stipulated time, the blocker (10) does not send a signal to block a vital point for the vehicle's operation, even without the presence of the OBD II protective cover. This starting time is adjustable, and can be from 10 to 60 seconds, for example. [0035] This need arises because the OBD II (On Board Diagnostics) port is used to connect the vehicle's computer with a device for reading various operating parameters of the vehicle, so if the blocker (10) were activated in In all cases where the protective cover was removed, it would make it impossible to use these reading and analysis devices to carry out a review, for example.
