Abstract
A control system includes a gateway controller and a remote controller. The gateway controller is configured to embed an HTTP request in a CAN bus-compatible message and transmit the CAN bus-compatible message onto a CAN bus. The remote controller is configured to receive the CAN bus-compatible message from the CAN bus, extract the HTTP request from the CAN bus-compatible message, and create an HTTP response to the HTTP request.
Claims18
A control system for a vehicle, the control system comprising:
- a vehicle gateway controller able to communicate via an Ethernet bus and being configured to embed an HTTP request in the data field of a CAN data frame, create a CAN bus-compatible message including the CAN data frame and a CAN remote frame, and transmit the CAN bus-compatible message onto a vehicle CAN bus;
- and
- a vehicle remote controller having a first web server, the remote controller being configured to receive the CAN bus-compatible message from the CAN bus, extract the HTTP request from the CAN bus-compatible message, and forward the HTTP request to the first web server for the first web server to create an HTTP response to the HTTP request.
A method for a vehicle control system having a gateway controller and a remote controller connected by a CAN bus, the gateway controller able to communicate via an Ethernet bus, the method comprising:
- receiving by the gateway controller an HTTP request by a message compatible with the Ethernet standard;
- creating by the gateway controller a CAN bus-compatible message including a CAN data frame and a CAN remote frame and embedding by the gateway controller the HTTP request in the data field of the CAN data frame;
- and
- transmitting by the gateway controller the CAN bus-compatible message through the CAN bus to the remote controller.
A method for a vehicle control system having a gateway controller and a remote controller connected by a CAN bus, the gateway controller able to communicate via an Ethernet bus, the method comprising:
- receiving by the remote controller from the CAN bus a CAN bus-compatible message including a CAN data frame and a CAN remote frame in which an HTTP request is embedded in the data field of the CAN data frame;
- extracting by the remote controller the HTTP request from the received CAN bus-compatible message;
- and
- creating by the remote controller an HTTP response to the HTTP request.
