An apparatus is provided for auto-locating positions of a plurality of wireless sensors on a vehicle. The apparatus comprises a receiving unit for receiving signals from the plurality of wireless sensors. The apparatus further comprises a processing unit arranged to calculate a probability value for each one of the plurality of wireless sensors based upon signals that have accumulated over a period of time to provide a table of probability values. Each probability value contained in the table during a calculation cycle of the processing unit is indicative of likelihood of one of the plurality of wireless sensors being located at a corresponding one of a plurality of positions on the vehicle. Each one of the plurality of wireless sensors is associated with the position having the highest probability value during the calculation cycle.

Method for auto-locating positions of a plurality of wireless sensors on a vehicle and an apparatus therefor

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.
