Efficient Reverse Navigation Technique for Autonomous Vehicles: Leveraging Front-Side Single Lidar for Turning Maneuvers

The front-facing lidar is extensively used to navigate the vehicle forward and detect obstacles. However, when this lidar is employed for reverse navigation, the vehicle faces the challenge of having two possible directions upon turning, leading to a decreased chance of precisely tracing its original path. This study presents two methods to address this issue: (i) Initial steering rotation adjustment and (ii) One directional Steering signal method. The findings demonstrate that both approaches enhance the accuracy of the reverse movement path followed by the vehicle. So this method reduces the dependency on multiple lidar sensors; a single lidar installed on the front side of a vehicle can be used for forwarding and reverse navigation.
