Method for determining lane of multi-lane road for vehicle, involves incrementing and decrementing value at driving lane change on driving lane adjacent in first and second directions

摘要

The method involves assigning a current driving lane (2.1) to a vehicle, where a value is assigned to the current driving lane. The value is incremented at the driving lane change on the driving lane adjacent in a first direction, and is decremented at the driving lane change on the driving lane adjacent in second direction. A start value is initialized in first drive on a road surface (1). The start value is reinitialized with one predetermined condition.
