A system with a first computer unit and with a second computer unit, wherein the first computer unit comprises a first interface to enable connection to at least one sensor and to at least one actuator, wherein the second computer unit comprises a second interface to enable connection to at least one sensor and to at least one actuator, wherein the first and the second computer units can be connected to each other by means of a further interface, wherein the actuator comprises an interface, wherein depending on the first or on the second operating state the interface determines whether a control command for a driving function is adopted by the first or the second computer unit, so that in the first operating state only the first computer unit can activate the actuator and in a second operating state only the second computer unit can activate the actuator.

Fail-safe EE architecture for automated driving

An automotive communication method includes installing a sensor within a vehicle such that the sensor is submerged in a liquid during operation of the vehicle and/or substantially surrounded by a metallic structure during operation of the vehicle. A long wave magnetic signal is transmitted from the sensor. The signal is indicative of a condition sensed by the sensor. The signal is wirelessly received at a controller disposed within the vehicle. Receipt of the signal at the controller is responded to by adjusting a display and/or a setting within the vehicle.

Magnetic field communication arrangement and method

A gateway module for connection of at least two sub-networks is described. A first sub-network of the at least two sub-networks supports a data transmission in accordance with a first communications protocol, especially CAN, FlexRay, LIN, MOST or Ethernet, and a second sub-network of the at least two sub-networks supports a data transmission in accordance with a second communications protocol, especially CAN, FlexRay, LIN, MOST or Ethernet. The gateway module has a configurable hardware circuit which is adapted to manipulate and forward data from the first sub-network and to the second sub-network taking into consideration the first communications protocol and the second communications protocol.

Gateway module for a communications system, communications system, and method for transmitting data between users of a communications system

A method for reprogramming a node of an electronic communication system includes transmitting a signal from a first node to a second node. The signal requests that the second node be reprogrammed. The signal includes an identification of the first node. The second node is used to broadcast the identification of the first node to other nodes in the communication system. The second node is reprogrammed only if a predetermined quantity of the other nodes confirm, based on the identification, that the first node is legitimate.

Security system and method for wireless communication within a vehicle

A wireless transmission method includes providing a commanding node and a plurality of sub-networks. Each of the sub-networks includes at least one responding node. Corresponding ones of a plurality of time slots are assigned to individual ones of the sub-networks based on at least one operational characteristic of the sub-networks. The time slots are disposed within a plurality of frequency channels. Communication is conducted between the commanding node and the sub-networks within the assigned time slots of the sub-networks.

Dynamic function slot assignment in intra-vehicular wireless networks

A method for synchronizing two communication networks of an electronic data-processing system, each of the networks including one or more respective nodes, may include establishing for each of the networks a respective time schedule that establishes at least one respective time slot for a respective synchronization message. The synchronization message time slots are established to coincide. The synchronization message of the first communication network is generated by one of the nodes of the first communication network. The synchronization message of the second communication network is generated as a function of the synchronization message of the first communication network.

An automotive electrical body system includes a plurality of electrical assemblies coupled to at least one automotive body component. Each of the assemblies includes a heating element for heating the at least one component, a motor for actuating the at least one component, or a switch configured to toggle the at least one component on and off. Each of the assemblies also includes a wireless communication module for receiving wireless signals, and, in response to the wireless signals, controlling operation of the heating element or motor. An electrical conductor interconnects each of the electrical assemblies and carries electrical power to each of the electrical assemblies.

Architecture for automotive electrical body systems

A wireless transmission method includes providing a commanding node and a plurality of sub-networks. Each of the sub-networks includes at least one responding node. Time slots are assigned to the sub-networks such that time slots assigned to each sub-network are interleaved in time with time slots assigned to at least one other sub-network. Within each time slot, at least one acknowledgement packet is transmitted from the at least one responding node before a command packet is sent from the commanding node within the time slot. Each at least one acknowledgement packet indicates whether or not a most recent command packet from the commanding node was correctly received by the responding node.

Protocol for wireless networks

A method for providing wireless communications between nodes of a vehicle includes providing a plurality of frequency channels on which the nodes of a first vehicle may wirelessly communicate. Wireless communication with a second vehicle adjacent to the first vehicle includes assigning a first of the frequency channels to the first vehicle for intra-vehicle transmissions within the first vehicle, and a second of the frequency channels to the second vehicle for intra-vehicle transmissions within the second vehicle. The first vehicle is prohibited from using the second frequency channel and the second vehicle is prohibited from using the first frequency channel.

A wireless network arrangement for a vehicle includes an electronic controller disposed within the vehicle. A plurality of wireless electronic components are disposed within the vehicle and are wirelessly communicatively coupled to the electronic controller. The components are networked together wirelessly such that members of any subgroup of the components can wirelessly communicate with each other.

Method and apparatus for customizing a wireless network architecture

A method is provided for operating a field bus network system having a ring topology, which has a master unit and a plurality of slave units, which are connected by a field bus in a ring topology. The method includes transmission of a data message by the master unit to a slave unit intended for receiving the data message, which has a first counter device and a second counter device, a count of the first counter device being used to display a number of required relay steps via interposed slave units in the ring topology up to the slave unit intended for receiving the data message and a count of the second counter device being used to display a number of completed relay steps via interposed slave units in the ring topology; the slave units modifying the count of the first counter device using a first predefined algorithm upon receipt of the data message and ascertaining on the basis of the modified count of the first counter device whether it is the slave unit intended to receive the data message; and the slave units modifying the count of the second counter device using a second predefined algorithm upon receipt of the data message.
