Risk estimation in non-line-of-sight scenarios

In this paper, a collision warning application is described. The collision warning application is in particular useful when the driver’s view is blocked due to a large vehicle. The risk estimation algorithm, which is originally designed and validated in scenarios with vulnerable road users, is here applied in a non-line-of-sight scenario with vehicles. In this experimental setup wireless communication is used as sensor instead to the traditional sensor systems, e.g. radar, lidar and/or vision. The applicability of the collision warning algorithm is shown in experiments with two Toyota Prius vehicles and a large truck
