- the brake-by-wire system is designed to detect an adjustment of a brake pedal device, which is used as an input device for the driver or user. In addition, it is provided to transmit at least one signal corresponding to the adjustment to an electronic computing device of the brake-by-wire system, whereby the electronic computing device can be designed as a control computer of a motor vehicle.

- the mechanical connecting element is arranged, which can be designed for a plug connection, for example.
- connection can also be made by a variety of methods, including clamping screws, solder connections or screw connections.
- the choice of method depends on a number of factors, including the type and size of the cables, the application in which they are used and the electrical requirements required, whereby according to the invention it is intended that the connection can be carried out particularly quickly, efficiently and easily by the user or driver, especially for a layperson. It is also intended that the connection is made safely and reliably using the connecting element and thus the exemplary cable connection in order to prevent electrical problems or a possible danger for the user or driver and the vehicle, which means that already known connections according to ISO standards are particularly advantageous for this. So that the vehicle knows which signal should be used for control, a separate electrical control unit (ECU) is integrated or installed in the brake pedal device, in particular in the pedal itself, for example, which prioritizes the signal from the connected control device.
- ECU electrical control unit
- a second interface and a second corresponding connecting element for the electronic coupling of the at least one control device via the second interface to the brake-by-wire system are arranged on the electronic computing device.

- the second possibility provides that the interface is no longer or not only installed in the brake pedal device, but that the control device can be connected directly to the electronic computing device or a central control unit, for example.
- the prioritization of the signals now takes place directly on the electronic computing device, with output signals from the brake pedal device and output signals from the control device being transmitted separately from one another to the electronic computing device.
- the signal is then processed by the electronic computing device, after which, for example, recuperation of an electric machine and/or direct use of the wheel brake is made to decelerate the vehicle as desired.

- the data module can also be connected to the server by establishing a network connection.
- the data module is configured to communicate with the server in compliance with security protocols. This may require configuration of network settings, including IP address, subnet mask and gateway.
- the data module connects to the server by using a wireless connection, in particular via LTE or other cellular network, to provide a connection to the Internet. This is a fast and reliable option, but is dependent on cellular network coverage. It is important to note that the exact steps to connect a data module to a server depend on the type of data module and server, as well as the protocols and network settings used.
- connection to the server enables external control of the control device, but it also enables logging of functions of the respective electronically coupled control devices, which can lead to desired monitoring and verification of the respective control devices in order to continuously improve the functionalities of the respective control devices or at least to provide assistance to a user or driver in the event of a failure.
- third parties can also be informed, in particular an emergency service, for example in the event of a failure of the control device and/or in the event of an accident, thereby increasing the safety of the driver or user.

- a connection is first established with, for example, the server or directly with the electronic computing device.
- the control device and the application are coupled to one another by a corresponding configuration in order to enable successful communication. This can be done by entering IP addresses, user names and passwords, in particular to recognize the user or driver and thus provide presettings, which makes setting and using the control device faster.
- the application can ultimately used to send commands to the control device and monitor its status. The control device can then react accordingly.
- the data module can be integrated in the electronic computing device, arranged as a separate module of the electronic computing device, arranged as a separate module of the control device or integrated in the control device.
- the commands and signals for controlling the control device and for the electronic coupling with the brake-by-wire system are generated, transmitted and executed accordingly. Overall, the mobile device, the application and the wireless connection make it possible to control and monitor the control device from anywhere, which not only enables fast, convenient, efficient and flexible control, but also is safe.
- a physical operating unit is arranged for switching the control device on and off.
- the operating unit is to be used as an emergency switch in order to interrupt the electronic coupling of the control device with the brake-by-wire system in an emergency situation and to enable the standard functioning of the motor vehicle, in particular essentially immediately.
- the operating unit is to be used to quickly and safely switch the break-by-wire system back to its original function if a problem occurs or there is a danger. If a problem occurs, such as a short circuit, overheating or another safety risk, the emergency switch, which is designed as a lever, button or switch, for example, can be triggered.
- a further aspect of the invention relates to a method for operating a brake-by-wire system of a motor vehicle, in which an adjustment of a brake pedal device is detected, at least one signal corresponding to the adjustment is transmitted to an electronic computing device of the brake-by-wire system and depending on the signal, a braking device of the motor vehicle coupled to the brake-by-wire system is at least partially controlled.
- the electronic computing device can be designed as a central control unit of the motor vehicle, wherein it is used to carry out calculations and to process data, in particular it is also designed to receive and transmit signals, data and information, both via cable or electronically and wirelessly via an arranged data module.
- At least one control device is electronically coupled to the brake-by-wire system via at least one interface arranged on the brake pedal device, wherein the at least one control device is connected to at least one connecting element arranged on the brake pedal device.
- the operation of the brake-by-wire system is thus carried out by various method steps, which are based on a control of electronic and mechanical components. For example, it is provided that a driver or a user presses the brake pedal of the brake pedal device, whereby an electrical signal is transmitted to the electronic computing device. This calculates the required braking force and sends electrical signals to the braking device, which actually exerts the braking force in order to at least partially brake the motor vehicle.
- a hydraulic pump and a reservoir can also be used in the brake-by-wire system to regulate the braking pressure and transmit it to the braking components.
- the signal generated by the control device is first transmitted to the electronic computing device, whereby the braking device is controlled as a function of the signals generated by the control device and transmitted to the electronic computing device.
- the at least one control device is electronically coupled to the brake-by-wire system via a second interface arranged on the electronic computing device, wherein the at least one control device is connected to a second mechanical connecting element arranged on the electronic computing device.
- a second mechanical connecting element arranged on the electronic computing device.
- the second connecting element is here For example, it can be arranged as a freely accessible plug connection on the dashboard, which is easily accessible and quickly available without the need for a tool or other device. This type of connection allows the driver or user to connect the control device easily and conveniently.
- a master-slave system is used to prioritize the at least one control device over that of the brake pedal device in the brake-by-wire system.
- the master-slave method is a technology that is used in data processing and data transmission to coordinate communication between several control devices, in this case between the brake pedal device and the connected control device.
- the electronic computing device is thus referred to as the "master” and the brake pedal device and the connected control device are referred to as the "slave”.
- the master is responsible for transmitting requests and commands to the slave devices and receiving the responses and data from these devices.
- the slave devices are responsible for receiving requests and commands from the master and responding accordingly.
- the electronic computing device is thus designed to prioritize the connected control device and use the data and information to control the brake device.
- the master-slave system is easy to implement and prevents multiple control devices from sending data at the same time, which can cause conflicts. It is also very efficient because it optimizes the use of resources by concentrating the responsibility for transmitting data on a single device. Overall, the master-slave system offers a way of simply and efficiently coordinating communication between the electronic computing device with the brake pedal device and the control device.
- the first possibility of an interface is an additional signal input in the brake pedal itself. Due to a defined interface, various devices for controlling the vehicle, namely the control device, can be connected to this input. For example, a driving school can simply connect a second set of pedals as the control device via a cable. A person with a disability, for example, has the option of using an alternative control unit for the brake, such as For example, to connect a joystick or a steering wheel rim. So that the vehicle detects which signal should be used for control, an electrical control unit (ECU) is installed in the brake pedal device, for example, which prioritizes the signal. For example, prioritization can be carried out using a master-slave process in the driving school car, with the input of the driving instructor being prioritized over that of the student driver.
- ECU electrical control unit
- the pedal is connected to the vehicle's central control unit.
- the electronic computing device designed as a central control unit is also connected to an infotainment system and a server of the manufacturer, to which a mobile device or a smartphone can in turn be connected via an application. This enables the control device or the new input device to be activated via the infotainment system or the smartphone.
- the second option for implementing the method and providing the arrangement is to not install an interface in the pedal, but to connect the control device directly to the central control unit. This saves the input on the brake pedal provided by the first connection element, but an additional input on the control unit and thus the second connection element is required.
- the prioritization of the signals now takes place in the central control unit. All other points correspond to the first option. It is therefore also possible here for the control device to be activated via the infotainment system or your own smartphone.
- the signal is then processed by the central control unit, after which, for example, the recuperation of an electric motor of an electric vehicle or a hybrid vehicle and/or a wheel brake are carried out and controlled accordingly in order to decelerate the vehicle as desired.
- a particularly advantageous feature of the invention is that the vehicle can be adapted to be accessible to disabled people, with a focus on braking, which is made significantly simpler and more cost-effective.
- complex and costly conversions such as those offered by third-party providers are avoided.
- Complex, external electronics can also be largely dispensed with, since essentially all components for prioritizing the input signals are already present in the vehicle.
- the main benefit of arranging a controller on a brake-by-wire system in this way is that the braking system can be better controlled and adapted using connected controllers.
- the system can be programmed to respond to various inputs from the controllers and also to, for example, driver behavior, road conditions and vehicle speed, thus providing a refined and tailored braking experience.
- the brake-by-wire system can be combined with the controller and with other advanced technologies such as anti-lock braking systems, traction control and stability control to provide even greater control and safety under different driving conditions.
- the invention offers more control and customization options, improved efficiency and increased safety, whereby a brake-by-wire interface is proposed for alternative operating units or for alternative control devices.
