Abstract
A controller forming one node of a local interconnect network in a vehicle and implementing a function associated with the vehicle is provided along with a method for communicating within the network. The controller includes a serial communication interface configured to communicate with a single wire serial communication bus through a local interconnect network transceiver. A processor coupled to the interface is configured to implement a process for transmitting data on the bus including determining whether the bus is in use by another node, generating, when the bus is not in use, a signal on the bus indicative of a forthcoming transmission, transmitting a predetermined portion of a frame of data on the bus, determining whether a data collision exists on the bus, transmitting, when a data collision does not exist, another predetermined portion of the frame, and terminating, when a data collision does exist, further transmission of the frame.
