A method establishes a vehicle area network on a vehicle having a tractor with a tractor wireless hub, the tractor connected to a first trailer having a first trailer wireless hub. The method activates a tractor hub and a first trailer wireless hub; and sharing credentials between the tractor wireless hub and the first trailer wireless hub according to an out-of-band pairing technique. Generally, a tractor wireless hub serves as an access point for a vehicle area network, but the access point may be centered by searching along a length of the vehicle to determine relative positions of the tractor wireless hub, the first trailer wireless hub, and the second trailer wireless hub; determining a centering positioning center according to the positions; and establishing the centered positioning center as the access point.
一种方法,在车辆上建立车辆区域网络,该车辆具有带有牵引机无线中枢的牵引机,所述牵引机连接到具有第一拖车无线中枢的第一拖车。该方法激活牵引机中枢和第一拖车无线中枢;以及根据带外配对技术在牵引机无线中枢和第一拖车无线中枢之间共享凭证。通常,牵引机无线中枢用作车辆区域网络的接入点,但所述接入点可以通过以下方式而被居中:沿着所述车辆的长度搜索以确定所述牵引机无线中枢、所述第一拖车无线中枢和所述第二拖车无线中枢的相对位置;根据这些位置确定居中定位中枢;并将所述居中定位中枢建立为所述接入点。
