1. 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.

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.

12. 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. - View Dependent Claims (13, 14, 15)

16. 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. - View Dependent Claims (17, 18)
