Title: METHOD FOR DETERMINING SWITCHED ROAD SIDE UNIT IN NAVIGATION SYSTEM AND RELEVANT APPARATUS
Abstract:
A method for determining a switched road side unit in a navigation system, comprising: an OBU acquiring RSU information provided by a CSU, acquiring a navigation path of a vehicle, and then, according to current position information, the navigation path of the vehicle and the RSU information, determining an ID of an RSU to which to switch. The OBU can determine an RSU switching object according to the vehicle navigation path and the RSU information, without performing determination according to the strength of a communication signal, and can also pre-determine the RSU switching object even when the vehicle moves at a high speed, thereby guaranteeing the rapid switching of an RSU and communication quality during RSU switching. In addition, communication is not required between RSUs, and a coverage region of adjacent RSUs is also not required to be known, so that while RSU switching is achieved, the complexity of an RSU can be reduced.
