Abstract (en)
[origin: WO9909719A1] A vehicle information system including a tag system (120B) mounted in a vehicle (100). The tag system (120B) transmits vehicle-related data acquired from the vehicle (100) to an interrogator (300B). The vehicle information system utilizes a bus (110) in the vehicle (100) with low-cost RF communications in the tag system (120B) and an interrogator (300B) to remotely access the vehicle-related data as the vehicle exits and enters a designated area. The interrogator (300B) provides the vehicle-related data acquired from the tag system (120B) to a host computer (320). The vehicle information system can use an encoding system including an encoder that Manchester encodes a data value to produce a coded data value and produces a first invalid Manchester encoded sequence as a start of frame. Also produced is a second invalid Manchester encoded sequence as an end of frame. A transmission packet is produced including the start of frame followed by the coded data value followed by the end of frame. The start of frame is a sequence of "110110" and the end of frame is a sequence of "001000".
