[017] O SISTEMA DE ALARME SONORO E VISUAL PARA FREIO ESTACIONÁRIO PNEUMÁTICO, HIDRÁULICO E/OU ELÉTRICO DE VEÍCULOS AUTOMOTORES consiste em um sistema (1) que pode ser implementado no freio estacionário pneumático, hidráulico ou elétrico de um caminhão, ônibus, tratores, guindastes, empilhadeiras, etrc. podendo ser ainda, implementando em um freio estacionário mecânico de um veículo de médio e pequeno porte. O sistema (1), é basicamente formado por uma central eletrônica (2) munida de um sensor de pressão (4), um dispositivo sonoro (3) e um dispositivo visual (10), de modo que, a central eletrônica (2) gerencia e processa os sinais do referido sensor de pressão (4), assim como, o de um dispositivo sonoro (3) e o dispositivo visual (10), visando aumentar a segurança do veículo, lembrando o motorista de acionar o freio estacionário quando necessário. [017] THE AUDIBLE AND VISUAL ALARM SYSTEM FOR PNEUMATIC, HYDRAULIC AND/OR ELECTRIC PARKING BRAKE OF MOTOR VEHICLES consists of a system (1) that can be implemented in the pneumatic, hydraulic or electric parking brake of a truck, bus, tractor, crane, forklift, etc. and can also be implemented in a mechanical parking brake of a medium or small vehicle. The system (1) is basically formed by an electronic control unit (2) equipped with a pressure sensor (4), an audible device (3) and a visual device (10), so that the electronic control unit (2) manages and processes the signals from said pressure sensor (4), as well as from an audible device (3) and the visual device (10), aiming to increase vehicle safety, reminding the driver to activate the parking brake when necessary.

[018] Em especial, o dispositivo sonoro (3) da central eletrônica (2) pode ser uma sirene, buzina e similares, para emitir um som de alerta quando necessário. O sensor de pressão (4) da central eletrônica (2) é utilizado para monitorar a pressão do ar no sistema pneumático do freio estacionário do veículo. A central eletrônica (2) também é composta por um engate rápido (5), que permite a entrada de ar no sensor de pressão (4), cujo engate rápido (5) é conectado ao sistema pneumático do freio estacionário de um caminhão ou ônibus através de uma conexão pneumática (6A) advinda de uma mangueira de conexão em T (6). [018] In particular, the sound device (3) of the electronic control unit (2) may be a siren, horn and the like, to emit a warning sound when necessary. The pressure sensor (4) of the electronic control unit (2) is used to monitor the air pressure in the vehicle's pneumatic parking brake system. The electronic control unit (2) also consists of a quick coupling (5), which allows air to enter the pressure sensor (4), whose quick coupling (5) is connected to the pneumatic parking brake system of a truck or bus through a pneumatic connection (6A) coming from a T-connection hose (6).

[019] O sensor de pressão (4) da central eletrônica (2) é conectado na parte elétrica (7) da porta do caminhão, ônibus, etc. diretamente na corrente 12/24v sem passar pela chave de ignição, que é acionado caso haja pressão no sistema e energiza a central eletrônica (2), e que da porta do caminhão, por meio de um condutor negativo (8), ao passo que, se a válvula manetim estiver acionada, (sem pressão no sistema) isto é, (freio estacionário ativado), e a porta do caminhão fechada ou aberta, o dispositivo sonoro (3) e o dispositivo visual (10) da central eletrônica (2) não são acionados. Contudo, caso a válvula manetim não esteja acionada, isto é, (freio estacionário desativado), que (contenha pressão no sistema) e a porta do caminhão se abra, o dispositivo sonoro (3) e o dispositivo visual (10) da central eletrônica (2) serão imediatamente acionados, lembrando o motorista de acionar o freio estacionário do caminhão. [019] The pressure sensor (4) of the electronic control unit (2) is connected to the electrical part (7) of the truck, bus, etc. door directly to the 12/24v current without going through the ignition key, which is activated if there is pressure in the system and energizes the electronic control unit (2), and that of the truck door, by through a negative conductor (8), whereas, if the lever valve is activated, (no pressure in the system) that is, (parking brake activated), and the truck door is closed or open, the audible device (3) and the visual device (10) of the electronic control unit (2) are not activated. However, if the lever valve is not activated, that is, (parking brake deactivated), (there is pressure in the system) and the truck door opens, the audible device (3) and the visual device (10) of the electronic control unit (2) will be immediately activated, reminding the driver to activate the truck's parking brake.

[020] Numa segunda forma de realização, a central eletrônica (2) do sistema (1), no presente invento, possui um rele (R) para inversão de sinais, o qual recebe alimentação de um condutor positivo (7), que também alimenta a central eletrônica (2). Ainda, um ponto de acionamento e retorno (P) é conectado no rele (R) e nos sensores de ocupação (11) inseridos em uma capa de ocupação (C), a qual, por sua vez, é revestida no assento (A) de um ônibus. Desta forma, os sensores de ocupação (11) detectam a pressão exercida no assento (A), mediante a presença do condutor, de modo que, os sensores de ocupação ao identificarem pressão exercida no assento (A), mediante a presença do condutor, tanto o dispositivo sonoro (3), como o dispositivo visual (10) não são acionados. Entretanto, quando os sensores de ocupação (11) ao não detectarem uma pressão exercida no assento (A), mediante a ausência do condutor, acionar imediatamente o dispositivo sonoro (3) e o dispositivo visual (10) para lembrar o condutor de acionar o freio estacionário. [020] In a second embodiment, the electronic control unit (2) of the system (1), in the present invention, has a relay (R) for signal inversion, which receives power from a positive conductor (7), which also powers the electronic control unit (2). Furthermore, a trigger and return point (P) is connected to the relay (R) and to the occupancy sensors (11) inserted in an occupancy cover (C), which, in turn, is covered in the seat (A) of a bus. In this way, the occupancy sensors (11) detect the pressure exerted on the seat (A), in the presence of the driver, so that, when the occupancy sensors identify pressure exerted on the seat (A), in the presence of the driver, both the audible device (3) and the visual device (10) are not activated.
