INTRODUÇÃO INTRODUCTION
[1] Refere-se o presente relatório descritivo a um pedido de patente de invenção para módulo eletrónico can para detecção de roubo ou furto com ação, local ou remota, de parada de funcionamento de veículos automotivos com injeção e/ou controle eletrónico do motor, pertencente ao campo dos equipamentos de segurança automotivos, dito módulo can desenvolvido a partir de um módulo configurado para a instalação no interior de um veículo ligado ao barramento CAN e de um módulo configurado para a instalação dentro da Unidade de Controle do Motor - UCM (ou seja, dois módulos), ambos desenvolvidos para detectar roubo ou furto do veículo e parar ou liberar o funcionamento do motor em veículos automotivos dotados de injeção eletrónica e/ou controle eletrónico do motor, no caso de veículos elétricos ou híbridos, ditos módulos desenvolvidos também para proporcionar auto monitoração do sistema e sendo que pelo menos um dos módulos é integrado com uma rede de dados de telefonia celular, satélites ou internet.

ESTADO DA TÉCNICA TECHNICAL STATUS
[2] Atualmente, os sistemas antifurto fazem uso da identificação das chaves originas do veículo, assim como da identificação do motorista autorizado a dirigir ou até mesmo do alarme automotivo contra invasão para coibir o roubo ou furto do veículo. [3] Todavia, hoje em dia os meliantes atingiram um tal nível de conhecimento dos sistemas antifurto, assim como de sistemas de rastreamento, que os permite neutraliza-los fácil e rapidamente seja pela posse das chaves originas, pela posse de códigos de identificação e/ou coação do motorista ou posse do controle remoto codificado ou até mesmo pela desativação física feita por bandidos especializados. Desta forma, uma vez paralisado um veículo para ser roubado ou furtado, o tempo para recolocá-lo em funcionamento, para retirá-lo da cena do crime, pode chegar a ordem de unidades de minutos, o que dá uma grande vantagem àqueles que perpetram o roubo. [2] Currently, antitheft systems make use of the identification of the vehicle's original keys, as well as the identification of the driver authorized to drive or even the car alarm against intrusion to prevent theft or theft of the vehicle. [3] However, nowadays miscreants have reached such a level of knowledge of anti-theft systems, as well as tracking systems, that it allows them to neutralize them easily and quickly, either by possession of the original keys, by the possession of identification codes and / or coercion by the driver or possession of the coded remote control or even by the physical deactivation made by specialized criminals. In this way, once a vehicle is paralyzed to be stolen or stolen, the time to put it back into service, to remove it from the crime scene, can reach the order of units of minutes, which gives a great advantage to those who perpetrate theft.
[4] Outro aspecto relativo aos sistemas antifurto atuais diz respeito ao fato de que eles não são capazes de detectar com eficácia as situações de roubo ou furto oriundas da ação de dispositivos bloqueadores de rádio frequência (BRF’s/Jammers) e/ou da alteração do comportamento previsto para o uso veículo. [4] Another aspect related to current antitheft systems concerns the fact that they are not capable of effectively detecting situations of theft or theft arising from the action of radio frequency blocking devices (BRF's / Jammers) and / or altering the expected behavior for vehicle use.
[5] Os sistemas antifurto atuais, portanto, não podem ser encarados como solução eficaz para evitar roubos ou recuperar veículos roubados ou furtados. [5] Current antitheft systems, therefore, cannot be seen as an effective solution to prevent theft or recover stolen or stolen vehicles.
[6] Desse modo, com a insegurança fazendo parte do nosso cotidiano mundial, fica evidente a necessidade de proporcionar às pessoas e empresas, meios eletrónicos eficientes de parada remota de seus veículos e que, ainda, aumentem em muito a possibilidade da recuperação física dos mesmos. [6] Thus, with insecurity as part of our worldwide daily life, it becomes evident the need to provide people and companies with efficient electronic means of remote stopping of their vehicles and that, still, greatly increase the possibility of physical recovery of their vehicles. themselves.
OBJETIVOS DA INVENÇÃO OBJECTIVES OF THE INVENTION
[7] Assim, o objetivo da presente patente é prover um módulo (sistema) que possibilite a parada do veículo a partir de um ponto remoto ou a parada automática através de meios locais (inteligência embarcada). [7] Thus, the objective of the present patent is to provide a module (system) that makes it possible to stop the vehicle from a point remote control or automatic stop using local means (embedded intelligence).
[8] Outro objetivo é prover um sistema que monitore e informe o estado e/ou acesso à instalação do próprio sistema, auto monitoração. [8] Another objective is to provide a system that monitors and reports the status and / or access to the installation of the system itself, self-monitoring.
[9] Outro objetivo é prover um sistema que possibilite a detecção de anomalias no sistema de modo a proporcionar a detecção antecipada do roubo ou furto do veículo, para permitir pronta resposta através de agentes de segurança e aumento ainda maior das chances de recuperação do património em questão. [9] Another objective is to provide a system that makes it possible to detect anomalies in the system in order to provide early detection of theft or theft of the vehicle, to allow prompt response through security agents and an even greater increase in the chances of recovering assets in question.
[10] Outro objetivo é prover um sistema que possibilite e alto grau de recuperação de veículos roubados. [10] Another objective is to provide a system that enables and a high degree of recovery of stolen vehicles.
[11] Outro objetivo é prover um sistema que possa ser instalado no veículo ao nível de fábrica ou em veículos já existentes em uso. DESCRIÇÃO RESUMIDA DA INVENÇÃO [11] Another objective is to provide a system that can be installed on the vehicle at the factory level or on existing vehicles in use. BRIEF DESCRIPTION OF THE INVENTION
[12] Tendo em vista os problemas do estado da técnica acima aludidos e no propósito de superá-los e considerando os objetivos acima relacionados e visando atendê-los foi desenvolvido o módulo eletrónico can para detecção de roubo ou furto com ação local ou remota de parada de funcionamento de veículos automotivos com injeção e/ou controle eletrónico do motor, objeto da presente patente, o qual é compreendido, essencialmente, por dois módulos associados: um módulo interno, compreendido por um módulo interno físico MIF (Hardware) ou módulo interno lógico MIL (Firmware), instalado dentro da Unidade de Controle do Motor - UCM e outro módulo externo ME físico (Hardware) instalado junto ao barramento CAN (Controller Area NetWork) do veículo ou qualquer outro barramento padrão de dados seriais, ambos módulos desenvolvidos para detectar roubo ou furto do veículo e parar ou liberar o funcionamento do motor em veículos automotivos dotados de injeção eletrónica e/ou controle eletrónico do motor, no caso de veículos elétricos ou híbridos, bem como ditos módulos são desenvolvidos também para proporcionar a sua auto monitoração, visando detectar a desativação do mesmo e sendo que pelo menos um dos módulos é integrado com uma rede de dados de telefonia celular, satélites ou internet. [12] In view of the problems of the state of the art mentioned above and in order to overcome them and considering the objectives listed above and aiming to meet them, the electronic module can was developed to detect theft or theft with local or remote action of shutdown of automotive vehicles with injection and / or electronic engine control, object of this patent, which is essentially comprised of two associated modules: an internal module, comprised of a physical internal MIF module (Hardware) or internal module logic logic (Firmware), installed inside the Motor Control Unit - UCM and another physical ME external module (Hardware) installed next to the CAN bus (Controller Area NetWork) of the vehicle or any other standard serial data bus, both modules developed to detect theft or theft of the vehicle and to stop or release the engine operation in automotive vehicles equipped with electronic injection and / or electronic engine control, in the case of electric or hybrid vehicles, as well as as these modules are also developed to provide their self-monitoring, aiming to detect the deactivation of the same and at least one of the modules is integrated with a cellular data network, satellites or internet.
[13] Assim sendo, quando um dos módulos do sistema detecta uma anomalia que caracterize furto ou roubo ou quando recebe um comando específico da central de operação (ou do próprio proprietário) via comunicação de dados de telefonia celular ou satelital, referido sistema, constituído por aludidos dois módulos, provoca a parada do motor do veículo. Referido sistema é constituído ainda para que a liberação do funcionamento do motor só seja possível através do envio de um comando específico e remoto para tal. O presente sistema, constituído pelos módulos interno e externo, é programado também para quando há uma tentativa de remoção do módulo externo instalado junto ao barramento CAN provocar a parada do motor pela detecção de sua ausência pelo módulo interno à Unidade de Controle do Motor - UCM, tal que o motor fique impossibilitado de funcionar e, portanto, o veículo permaneça imobilizado. [13] Therefore, when one of the system's modules detects an anomaly that characterizes theft or theft, or when it receives a specific command from the operation center (or from the owner itself) via cellular or satellite data communication, said system, constituted by two modules, it causes the vehicle's engine to stop. Said system is also created so that the engine can only be released by sending a specific and remote command to do so. The present system, constituted by the internal and external modules, is also programmed for when there is an attempt to remove the external module installed next to the CAN bus, causing the motor to stop by detecting its absence by the module internal to the Motor Control Unit - UCM , such that the engine is unable to run and therefore the vehicle remains stationary.
[14] Assim, a partir da instalação e funcionamento dos módulos propostos e na hipótese de tentativa de roubo ou furto do veículo, a possibilidade de recuperação do mesmo será potencializada, na medida em que referido sistema proporciona, como recurso adicional ao veículo, uma ação remota de sua parada imediata. [14] Thus, from the installation and operation of the proposed modules and in the event of attempted theft or theft of the vehicle, the possibility of its recovery will be enhanced, in the insofar as this system provides, as an additional resource to the vehicle, a remote action of its immediate stop.
[15] Além da parada por comando remoto, o presente sistema possibilidade ainda parada automática por meios locais (inteligência embarcada) caso haja evidência física de que o veículo está sendo roubado ou furtado, como, por exemplo, através da ação de bloqueadores de rádio frequência (BRF/Jammer), alteração do comportamento previsto do veículo, violação ou mesmo retirada ou substituição do presente sistema. [15] In addition to the remote control stop, the present system also allows automatic stop by local means (embedded intelligence) if there is physical evidence that the vehicle is being stolen or stolen, such as through the action of radio blockers. frequency (BRF / Jammer), alteration of the expected behavior of the vehicle, violation or even withdrawal or replacement of this system.
[16] Desse modo, a presente solução de detecção de roubo ou furto se diferencia dos atuais e já conhecidos sistema embarcados veiculares por um motivo básico e fundamental: Os sistemas veiculares atuais não são capazes de detectar com eficácia as situações de roubo ou furto oriundas da ação de dispositivos bloqueadores de rádio frequência (BRF’s/Jammers) e/ou alteração do comportamento previsto para o uso veículo, o que é possível com o presente módulo, constituído pelos módulos interno e externo. Somado a isso, o sistema aqui proposto, é capaz de atuar junto a Unidade de Controle do Motor (UCM), via barramento CAN e/ou qualquer outro barramento padrão de comunicação serial, de forma a parar de modo seguro o funcionamento do motor, assim como liberá-lo via comando remoto. Dessa forma, nem o meliante, ou o motorista sob coação do bandido tem poder para colocar o veículo em funcionamento novamente. [16] Thus, the present theft or theft detection solution differs from the current and well-known embedded vehicle systems for a basic and fundamental reason: Current vehicle systems are not able to effectively detect theft or theft situations arising the action of radio frequency blocking devices (BRF's / Jammers) and / or altering the behavior expected for vehicle use, which is possible with this module, consisting of the internal and external modules. In addition, the system proposed here, is able to act together with the Motor Control Unit (UCM), via CAN bus and / or any other standard serial communication bus, in order to safely stop the motor operation, as well as releasing it via remote control. Thus, neither the miscreant, nor the driver under duress by the bandit has the power to get the vehicle running again.
[17] Em face de tais funcionalidades do presente sistema, este possibilita alto grau de recuperação dos veículos roubados ou furtados. Sua forma de instalação, via barramento CAN e/ou qualquer outro barramento serial padrão do veículo, permite que o mesmo seja um acessório original de fábrica ou que possa ser instalado após a venda do veículo. [17] In view of these functionalities of the present system, it allows a high degree of recovery of stolen or stolen vehicles. Its installation method, via CAN bus and / or any other standard serial bus on the vehicle, allows it to be an original factory accessory or can be installed after the vehicle is sold.

[26] O módulo interno é composto pelo módulo interno lógico MIL 20 ou módulo interno físico MIF 30, os quais são mutuamente excludentes, ou seja, apenas um deles é implementado no interior da Unidade de Controle do Motor UCM 101. Assim, a depender das características da UCM 101 , escolher-se-á o MIL 20 ou o MIF 30 para ser instalado em seu interior. [26] The internal module consists of the internal logic module MIL 20 or the physical internal module MIF 30, which are mutually exclusive, that is, only one of them is implemented inside the Motor Control Unit UCM 101. Thus, depending characteristics of UCM 101, MIL 20 or MIF 30 will be chosen to be installed inside.
[27] O módulo interno lógico MIL 20 é um complemento do firmware já presente na UCM 101 e é composto por quatro camadas (fig. 3A): a Interface lógica CAN 21 , que se comunica diretamente com o barramento CAN 100; o driver CAN 22, que interpreta as informações que vão para o barramento CAN 100 e as que vem dele, segundo o protocolo CAN específico da UCM 101 ; a interface lógica 23, que faz o acionamento e desacionamento do motor do veículo e, por fim, a aplicação 24, que contém toda lógica de funcionamento da solução. [27] The MIL 20 internal logic module is a complement to the firmware already present in UCM 101 and consists of four layers (fig. 3A): the CAN 21 logic interface, which communicates directly with the CAN 100 bus; the CAN 22 driver, which interprets the information that goes to the CAN 100 bus and the information that comes from it, according to the specific CAN protocol of UCM 101; the logical interface 23, which activates and deactivates the vehicle's engine and, finally, application 24, which contains all the solution's operating logic.
[28] O módulo interno físico MIF 30 (fig. 3B) é um conjunto de circuitos eletrónicos específicos que são incorporados aos circuitos da própria UCM 101 e são compostos de uma fonte de alimentação ALM 31 , para converter a alimentação externa nas tensões de trabalho do módulo; uma bateria interna BAT 32, para alimentar os circuitos na ausência de alimentação externa, uma interface CAN 33, para se comunicar com o barramento CAN 100; um sensor de alimentação externa SAL 104, que monitora a alimentação externa; um sensor de violação interno VLI 34, que monitora a tentativa de abertura da UCM 101 ; um sensor de Ignição IGN 105, que monitora o estado do sinal de ignição; uma memória não volátil MEM 35, para armazenar permanentemente parâmetros de identificação, parâmetros de operação e parâmetros de situação de dito módulo MIF 30; um conjunto de chaves eletrónicas 36, que geram os sinais eletrónicos necessários ao funcionamento ou parada do motor; e uma CPU 37, que faz o processamento das informações da interface CAN 33, que faz a leitura e escrita na memória não volátil MEM 35, que faz o processamentos das informações dos sensores de alimentação externa SAL 104, violação interna VLI 34 e sensor de ignição IGN 105. Por fim, a CPU 37 faz o acionamento do conjunto de chaves eletrónicas 36 que comandam a UCM 101 para parar ou liberar o funcionamento do motor. [28] The physical internal module MIF 30 (fig. 3B) is a set of specific electronic circuits that are incorporated into the circuits UCM 101 itself and are composed of an ALM 31 power supply, to convert the external power into the module's working voltages; an internal battery BAT 32, to feed the circuits in the absence of external power, a CAN interface 33, to communicate with the CAN 100 bus; an external 104 SAL power sensor, which monitors external power; an internal VLI 34 tamper sensor, which monitors the attempt to open UCM 101; an IGN 105 Ignition sensor, which monitors the status of the ignition signal; a MEM 35 non-volatile memory, for permanently storing identification parameters, operating parameters and status parameters of said MIF module 30; a set of electronic keys 36, which generate the electronic signals necessary for the motor to start or stop; and a CPU 37, which processes the information from the CAN 33 interface, which reads and writes the MEM 35 non-volatile memory, which processes the information from the SAL 104 external power sensors, internal violation VLI 34 and ignition IGN 105. Finally, CPU 37 activates the set of electronic keys 36 that control the UCM 101 to stop or release the engine.
[29] Assim constituído o arranjo (embarcado no veículo automotor V1 10), para o funcionamento do sistema (FIG. 4), tem-se que, em uma possibilidade, o motor do veículo V1 10 é desligado pela ação conjunta do módulo externo ME 2, modulo interno MIL20/MIF30, sensor de Ignição ING105, barramento CAN 100 e UCM 101 , sensor de violação interna VLI 34 tal que: [30] 1 ) - Quando o MIL20/MIF30 instalado junto à UCM 101 , detecta alguma anomalia através da ausência do módulo externo ME 2 no barramento CAN100 ou pela presença de um código de parada no barramento CAN100 gerado pelo módulo externo ME 2 ou por uma violação interna detectada pelo sensor de violação interno VLI 34 a UCM101 recebe uma ordem para o motor parar. [29] Thus the arrangement (embedded in the V1 10 motor vehicle) constituted, for the system to function (FIG. 4), it is necessary that, in one possibility, the motor of the V1 10 vehicle is turned off by the joint action of the external module ME 2, MIL20 / MIF30 internal module, ING105 Ignition sensor, CAN 100 and UCM 101 bus, VLI 34 internal violation sensor such that: [30] 1) - When the MIL20 / MIF30 installed next to the UCM 101, it detects any anomaly through the absence of the external module ME 2 on the CAN100 bus or by the presence of a stop code on the CAN100 bus generated by the external module ME 2 or by an internal violation detected by the internal violation sensor VLI 34 the UCM101 receives an order for the motor to stop.
[31] 2) - Se o sensor de ignição ING 105 sinalizar que o motor está em funcionamento, então o motor será parado de forma progressiva, começando com pequenas falhas até sua parada total. [31] 2) - If the ignition sensor ING 105 signals that the engine is running, then the engine will be stopped progressively, starting with minor faults until its complete stop.
[32] 3) - Mas se o sensor de ignição IGN 105 sinalizar que o motor já está parado, então o mesmo permanecerá parado indefinidamente. [32] 3) - But if the IGN 105 ignition sensor signals that the engine is already stopped, then it will remain stopped indefinitely.
[33] 4) - Uma vez parado, o motor só voltará a funcionar quando receber um comando específico de liberação enviado pelo módulo externo ME 2. [33] 4) - Once stopped, the motor will only start again when it receives a specific release command sent by the external module ME 2.
[34] 5) - Para tanto, o módulo MIL 20 ou MIF 30 também envia para o módulo externo ME 2 uma semente de ID dinâmico via barramento CAN 100, a qual será usada pelo módulo externo ME 2 para gerar um novo ID dinâmico que indicará sua presença e, portanto, normalidade no barramento CAN 100, proporcionando assim a geração de comando específico de liberação do motor enviado pelo modulo externo ME 2. [34] 5) - For this purpose, the MIL 20 or MIF 30 module also sends a dynamic ID seed via the CAN 100 bus to the external module ME 2, which will be used by the external module ME 2 to generate a new dynamic ID that it will indicate its presence and, therefore, normality on the CAN 100 bus, thus providing the generation of a specific motor release command sent by the external module ME 2.
[35] Já a finalidade do módulo externo ME2 é enviar comando de parada ou de liberação do motor para o módulo MIL20 ou MIF30 via barramento CAN 100, monitorar anomalias do sistema que caracterizem roubo, furto, ou mau funcionamento do mesmo, enviar informação da situação do sistema para a central de monitoramento 201 , via modem 8 de rede de telefonia celular 202 ou satelital 203. E, também, dito módulo externo ME 2 tem função de receber comandos da referida central 201 . [35] The purpose of the external ME2 module is to send a stop or motor release command to the MIL20 or MIF30 module via CAN 100 bus, monitor system anomalies that characterize theft, theft, or malfunction, send information from the system situation for the monitoring center 201, via modem 8 of cellular network 202 or satellite 203. Also, said external module ME 2 has the function of receiving commands from said central 201.
[36] Assim, o funcionamento do módulo externo ME 2 é totalmente controlado pela sua CPU 5 que, quando alimentada pela fonte de alimentação ALM 14, faz com que: [36] Thus, the operation of the external module ME 2 is completely controlled by its CPU 5 which, when powered by the ALM 14 power supply, causes:
[37] 1 ) - Seja Enviado um comando de parada para o módulo interno MIL20/ MIF30 quando dito módulo externo ME 2 detectar alguma anomalia nos sensores 102, 103, 1 1 , 12, 6, 4 que caracterize roubo ou furto ou quando receber da central de monitoramento 201 , via rede de telefonia celular 202 ou satelital 203, um comando específico de parada do motor. [37] 1) - A stop command is sent to the internal module MIL20 / MIF30 when said external module ME 2 detects an anomaly in the sensors 102, 103, 1 1, 12, 6, 4 that characterizes theft or theft or when receiving from the monitoring center 201, via cellular network 202 or satellite 203, a specific engine stop command.
[38] 2) - Porém, a CPU 5 enviará um comando de liberação do motor ao módulo MIL20 ou MIF30 apenas quando dita CPU 5 receber um comando de liberação do motor enviado pela central de monitoramento 201 , desde que esta não detecte qualquer anomalia nos referidos sensores 102, 103, 1 1 , 12, 6, 4. Ou dita CPU 5 enviará comando de liberação para MIL 20 ou MIF 30 se receber uma contrassenha válida gerada pela central 201 , a qual será temporariamente armazenada no smartphone 300 do usuário 400 e transferida para o módulo externo ME 2 via interface bluetooth 9, quando não for possível enviar comandos diretamente da central 201 para o veículo V 1 10. [38] 2) - However, CPU 5 will send an engine release command to the MIL20 or MIF30 module only when said CPU 5 receives an engine release command sent by monitoring center 201, as long as it does not detect any anomalies in the said sensors 102, 103, 1 1, 12, 6, 4. Or said CPU 5 will send a release command to MIL 20 or MIF 30 if it receives a valid password generated by the central 201, which will be temporarily stored in the smartphone 300 of the user 400 and transferred to the external module ME 2 via bluetooth interface 9, when it is not possible to send commands directly from the control panel 201 to the vehicle V 1 10.
[39] 3) - Ao perceber alguma alteração na situação do sistema ou se receber um comando da central de monitoramento 201 solicitando a situação do sistema, a CPU 5 enviará esta informação para a central 201 via modem 8 de rede de telefonia celular 202 ou satelital 203. [39] 3) - Upon noticing any change in the system situation or receiving a command from the monitoring center 201 requesting the system situation, CPU 5 will send this information to central 201 via modem 8 of cellular network 202 or satellite 203.
