Abstract
A vehicle control module includes a vehicle device and a vehicle network interface. The vehicle device is operable to perform a vehicle function. The vehicle network interface facilitates communication regarding the vehicle function between the vehicle device and a vehicle network fabric in accordance with a global vehicle network communication protocol.
Claims20
A vehicle module, comprising:
- a network port configured to support communications between a plurality of vehicle devices and a vehicular communication network in accordance with a communication protocol of the vehicular communication network, the plurality of vehicle devices comprising one or more sensors, actuators, or electronic control units (ECUs);
- a wireless unit configured to communicate wirelessly and with the plurality of vehicle devices;
- a network buffer coupled to the network port;
- and
- processing circuitry configured to cause the vehicle module to operate in a wireless mode, a wired mode and a concurrent mode, wherein in the wireless mode the network buffer and the network port are inactive and the wireless unit is active, wherein in the wired mode the wireless unit is inactive and the network buffer and the network port are active, and in the concurrent mode the wireless unit, the network buffer and the network port are active.
A vehicle module comprising:
- a plurality of vehicular network interfaces configured to support communications between a plurality of vehicle devices and a vehicular communication network;
- a network port;
- a wireless unit configured to communicate wirelessly and with the plurality of vehicle devices;
- a network buffer coupled to the network port;
- a switching circuit coupled to the network buffer and the plurality of vehicular network interfaces, the switching circuit configured to facilitate communication of packets between the plurality of vehicle devices and the vehicular communication network via the network port;
- and
- processing circuitry coupled to the switching circuit and the network buffer, the processing circuitry configured to cause the vehicle module to operate in a wireless mode, aa wired mode and a concurrent mode, wherein in the wireless mode the network buffer and the network port are inactive and the wireless unit is active, wherein in the wired mode the wireless unit is inactive and the network buffer and the network port are active, and in the concurrent mode the wireless unit, the network buffer and the network port are active.
A method of operating a network module comprising a network port configured to support communications between a plurality of vehicle devices and a vehicular communication network in accordance with a communication protocol of the vehicular communication network, the plurality of vehicle devices comprising one or more sensors, actuators, or electronic control units (ECUs), a wireless unit configured to communicate wirelessly and with the plurality of vehicle devices, a network buffer coupled to the network port, the method comprising:
