If the system detects a vehicle approaching from either side while moving backward, it warns the driver of dangers in the following way.
Limitations of the detectability of RCTA
Since the detectability of RCTA is limited, the RCTA may not operate properly in parking areas in which the parking spaces are drawn diagonally to the driving lanes.
