Abstract :

Autonomous car driving, v2v and v2x communications are the future trends in automobiles. So Radars, Lidars, Sonars, Cameras and various communication devices will drive our vehicle in nearby future. These devices will be of assistance in lane change, traffic assist, overtaking, pedestrian detection, autonomous parking, assistance to keep safe distance and adaptive cruise control. So the position of these sensors in the vehicle is very important. Software used in these sensor ECUs should take care of all the safety features. Since these physical sensors detects the targets and provide warning based on their lobe angle, the alignment of the sensors in the vehicle is very important to provide correct warning to driver. These alignments have to be verified in factory and servicing stations. The alignment algorithm used in the sensor ECUs will continuously check the alignment while running the vehicle (auto alignment checking). Alignment algorithms have to take care of some safety features which are very important for passenger safety. Even a small change in alignment angle beyond the tolerance level will give wrong information to driver. Due to the wrong alignment (or wrong alignment angle input) sensors will not be able to detect targets properly. Hence, software will not be able to provide desired results. This paper describes different safety features that need to be implemented in these sensor ECUs. It also describes different problems of the current softwares used in radar ECUs and also proposes different methods/approaches to solve these problems. The paper also proposes the concept of dual security service layer in sensor ECUs.
